Aim of Investigation To determine the frequency and seventy of chronic pain
in patients after trauma and elective trauma surgery
Methods Approval by the Ethics Committee of our institution Prospective cohort
study of 201 consecutive patients admitted for trauma surgery Measurement of chronic pain severity
using an established questionnaire instrument seven months after surgery Chronic Pain Grading
rates chronic pain seventy as follows Grade 0 = pain free, Grade I = low pain intensity and low
pain-related disability. Grade II = high pain intensity and low pain-related disability, Grade
III = high pain-related disability and moderately limiting, and Grade IV = high pain-related disability
and severely limiting
Results Seven months after operation, 159 trauma patients (79%) were interviewed
by telephone Prevalence of chronic pain seven months after surgery Grade 0 in n=61 patients (38
4%), Grade I in n=54 (34.0%), Grade II in n=12 (7 5%), Grade III in n=9 (5 7%) and Grade IV in
n=23 (14 5%) subjects Conclusion In a previous study of chronic pain grading in 1016 normal subjects
4 5 % showed pain and disability corresponding with chronic pain grade III and IV in our study
In our study, 20 2% of trauma patients showed increased chronic pain ratings seven months after
trauma Persistent pain may increase the nsk to develop chronic pain

Aim of Investigation. To investigate median nerve mobility in patients with
chronic diffuse arm pain associated with repetitive hand and finger use (often termed RSI or CTD)
Methods. Subjects were female, age range 23 - 30 years Subjects were imaged
lying supine in an open access MR scanner (OPEN Viva, 0.2 T, Siemens) with their wrist immobilised
in splints in neutral, 30° flexion and 30° extension MRJ was performed on 8 contiguous 5mm slices
aligned perpendicular to the nerve, using a T2 weighted fast spin echo
Results. During wnst extension the nerve was compressed in a saggital plane
against the flexor retmaculum During wnst flexion, nerve movement in a lateral and postenor direction
was observed in all control subjects, the median nerve becoming interposed between the tendons
of flexor pollicis longus and superficialis. The patients did not demonstrate this degree of movement,
the nerve remaining closely associated with the flexor retmaculum Conclusions. Patients with chronic
diffuse forearm pain show greatly reduced mobility of the median nerve at the wnst This is likely
to cause abnormal stress on the nerve dunng hand activities and in turn may cause abnormalities
in nerve function that can contnbute to painful symptoms

Aim of Investigation To registrate the pain relief in haemophilia patients
with joint haemorrhagia after Koate-HP treatment
Methods Individual patient questionnaire form to mark the reactions and time
when the pain relief appears
Results A group of 15 haemophilia patients who have been previously transfused
cryoprecipitate, were again questioned for pain relief within Koate-HP infusion. The pain relief
for two of the patients was marked after the second hour, four of them noted slight relief after
the 8th hour, while for the rest -the pain relief was after the 10th hour
Conclusion. We make this announcement to state that after Koate-HP application
no pain relief effect was registered in the first hour, as we have had during cryoprecipitate
treatment, an important clinical symptom for the politraumatiezed haemophilia patient We believe
our observations will be a challenge for investigators and up-to-date technologists as well

Interaction, Aalborg Univ, Denmark
Aim of the Investigation. Soft-tissue injury in whiplash trauma may play
a role for long lasting neck and jaw-muscle pain Pressure algometry in neck and jaw muscles was
used to assess deep muscle pain after whiplash in a prospective study at regular intervals from
trauma to six months after injury
Methods. 142 consecutive acute whiplash patients (M 67, F 75, Age 35 5±10.7)
exposed to rear-end collision in motor vehicle accidents Patients with fractures, dislocation,
unconsciousness, or amnesia were excluded from the study Whiplash patients were compared with
33 sex and age-matched controls exposed to acute, non-sport ankle distortion (M 14, F 19, Age.
32 8±9 9) Patients and controls were seen within 1 week, 1, 3, and 6 months after accident At
every visit, pressure algometry (Somedic) was performed 3 times above each of 10 neck- and jaw-muscle
spots and 3 times on a reference point (3rd left finger, PIP) Briefly, the al-gometer was placed
nght-angled on the muscle Probe area one square centimeter, slope control desired rate of change
of pressure at 20 kPa/s Individual regression lines for the sums of 30 pressure pain detection
values (total PPDT) obtained at each visit were computed Patients and controls seen more than
once were used for analysis. Total PPDT for day 90 was computed from individual line parameters,
and unpaired t-test was applied on normally dis-tnbuted data
Results. Total pressure pain detection threshold was significantly lower
in whiplash patients (P<0 05) than in controls Comparing matched patients and controls only,
this was even more pronounced (P<0 002) There were no differences at control site (P>0.30)
for the entire whiplash group, and for the matched patients and controls (P>0.06).
Conclusion: Cervical distortion patients (whiplash patients) have significantly
decreased pain detection thresholds in the neck muscles and jaw muscles compared to another acute
distortion condition. Pressure algometry can distinguish the differences in muscle-pain between
whiplash patients and a control group.
ALTERATIONS IN PAIN INTENSITY INFLUENCE SOMATOSENSORY PERCEPTION IN PATIENTS SUFFERING
FROM SUBACUTE/CHRONIC LATERAL EPICONDYLALGIA
Ann-Sofie Leffler*. Eva Kosek, Per Hansson, Neurogenic Pain Unit, Dept of Rehabilitation
Medicine, Karolinska Instt/Hospital S-171 76 Stockholm, SWEDEN.
Aim of Investigation: To investigate the influence of pain intensity on sensibility
to various somatosensory modalities in patients with subacute/chronic lateral epicondylalgia.
Methods: Thermal sensitivity (Thermotest), pressure pain sensitivity (pressure
algometer) as well as low threshold mechanoreceptive function (von Frey) was assessed in the local
pain area and the area of pain referral in 10 patients before and following pain provocation (weight
lifting). A local anaesthetic was then injected into the most painful area and the quantitative
sensory testing was repeated in the area of pain referral. The contralateral arm served as control
and was treated and injected accordingly.
Results: There was no difference in sensibility between the affected and
the unaffected arm in the local pain area during the whole experiment. In the area ofpain referral
allodynia to warmth (p<0.04) was found during the whole experiment. Repeated wrist movements
resulted in significantly increased pain intensity in the affected arm (p<0.001) but not contralaterally.
In the affected arm sensibility to light touch decreased following pain provocation (p<0.03)
but normalised following injection of local anaesthetic while no changes were seen contralaterally.
Conclusions: The sensitivity to light touch in the area of pain referral was the only modality
affected by the intensity of ongoing pain.
EFFECT OF WHIPLASH INJURY ON CRANIO-CERVICO MANDIBULAR PAIN
Ida Marini. Federico Vecchiet*, Ugo Capurso*, Dept of Oral Surgery, School of Dentistry,
Univ of Bologna, Italy
Aim of Investigation: To show the relationship between the chronic pain in
the cranio-cervico mandibular area and whiplash injury.
Methods: Forty-one patients (25 female and 16 male) with a mean age of 31.9
years, ranging from 16 to 65 years were examined. The symptoms had developed after a whiplash
injury 8 months to 3 years previously. Patients were excluded if they had only clicking in the
temporomandibular joint (TMJ) without pain or they had previous disc disease or facet joint denervation.
Examination of the patients included the following: muscle and jaw palpation, registration of
jaw sounds and jaw movements. Diagnosis was based on the Research Diagnostic Criteria for temporo-mandibular
disorders (RDC/TMD). The clinical diagnoses were verified by tomography. Headache frequencies
were also pointed out.
Results: 9% of the patients registered click and pain in TMJ and 60% of the
cases had difficulty in opening the mouth. 92% of pain was found in the neck and 46% in the head.
The patients gave 8 as the intensity of spontaneous pain using the visual analogue scale (VAS).
Latent or active Trigger Points (TrPs) were found in 93% of the subjects. The involved muscles
were: trapezius (98%), splenius (85%), stemocleido-mastoid (75%), masseter (52%) and temporal
(5%). The radiological condilar position, according to Pullinger method, was: bilateral centred
41% (17); posterior and centred 37% (15); bilateral posterior 22% (9).
Conclusions: The incidence of clicking with TMJ pain in whiplash patients
was low. All the patients had the TrP in the muscles of the neck and of the face. Their general
muscle problems may affect posture, respiration pattern and general body function. Our results
so far show that an early onset of treatment has the fastest and best results.
TREATMENT OF PAIN IN COXARTHROSIS
Sogorescu Eleonora. MD; Valcu Valeria, MD; Dumitrescu Eugenia, MD, Balneoclimatology
and Medical Rehabilitation Clinic ofCalimanesti, Romania
Aim of Investigation: The severe functional prognosis ofcoxar-throsis, which
sometimes leads to serious disabilities ("Kills the least, but invalidates the most")
determines us to approach the methodology of treatment for this disease in balneary spas. The
present paper proposes to follow the evolution of the pain parameter on coxarthrosis-affected,
under the influence of the physio-kyneto-balneary treatment carried out in our spa on a 18-21
days' period.
Method: We conducted our study on a lot of 80 patients under the treatment
in 1998; the appreciation of the pain parameter was made following the Bertrand rating (0 - painless;
1 - little pain; 2 - permanent pain, calmed down by resting- 3 - continuous pains, day and night).
Here are the therapeutic means we used of: hygieno-dietetic regimen, drugs and physiotherapeutic
treatment massage, kyneto-therapy in sulphurous water basin, kyneto-therapy indoors, procedures
with a sedative effect.
Results: The pain parameter evaluated following the Bertrand rating proved
an amelioration in 78% of the cases, as compared to the referential lot (that only followed the
drug treatment), on which we obtained good results in 50% of the cases.
Conclusions: Coxarthrosis is a degenerative affection marked by its disabilitation
character, thus representing one of the most difficult problems in the rheumatological practice.
The pain control in cox-arthrosis makes possible the treatment of the disorders concerning the
mobility and stability at hip level, thus assuring a good rehabilitation for the patients presenting
this affection.
DIFFERENTIAL PREDICTORS OF PAIN AND DISABILITY IN PATIENTS WITH WHIPLASH
Michael JL Sullivan, Maurecn E. Sullivan & W. Stanish, Dept of Psychology, Dalhousie
Univ, Halifax, Nova Scotia, B3H 4J1
Aim of Investigation: To compare the relative strength of psychological variables
in predicting pain and disability in patients with whiplash injuries.
Methods: Participants were 73 (20 men, 53 women) consecutive referrals to
the Atlantic Pain Clinic, a multidisciplinary treatment centre for the management of persistent
pain disorders. All patients sustained injuries in rear-end motor vehicle accidents. All had a
diagnosis of whiplash and all were involved in litigation. Patients completed measures of pain,
disability, catastrophizing, state and trait anxiety, and depression.
Results: The results of regression analyses showed that psychological variables
accounted for 20% of the variance in the prediction of pain severity. Psychological variables
accounted for 43% of the variance in the prediction of perceived disability. Trait Anxiety was
the best single predictor of pain, catastrophizing was the best single predictor of disability.
Conclusions: Increasingly, there are indications that predictors of pain
may differ from predictors of disability. The results of the present research show that psychological
factors accounted for more than twice the variance in disability ratings as compared to pain ratings.
The results are consistent with views suggesting that intervention programs should target reductions
in disability rather than reductions in pain.
PAIN AFTER REPLANTATION AND REVASCULARIZATION
Saranatra Waikakul, Dept ofOrthopaedic Surgery, Faculty of Medicine, Siriraj Hospital,
Mahidol Univ, Bangkok, Thailand
Aim of Investigation: To find out prevalence and natural history of chronic
pain after replantation in a prospective survey.
Method: All patients who had successful replantation and revascu-larization
were evaluated about their chronic pain. Patients' biodata and characteristics of the injuries
were recorded and correlation of these data to the severity and type of pain were analyzed. All
patients were followed up at least 2 years. VAS was used to define pain severity.
Result: 39 of the 428 patients (9%) who underwent digital replantation and
20 of the 82 patients (24%) who underwent major limb replantation had moderate to severe chronic
pain syndrome at the 6 month follow up. Surgical reconstruction of motor and sensory function
could reduce pain significantly in most of the patients. At the 2 year follow up only 2 patients
in the major limb replantation group had significant pain. However most of the patients who had
pain had poor functional outcomes.
Conclusion: Chronic pain syndrome after replantation and revas-cularization
is a rather common in major limb replantation and should be controlled to get good functional
results.
EFFICACY OF FISIOTHERAPY ON KNEE OSTEOARTHRITIS
I. Paturusi, C. Rasjad, A. Husain
Purpose: This study was intended to assess efficacy offisiotherapy compared
to drug treatment on patients with knee osteoarthritis using Koshino Scores. In addition, incidence
of osteoarthritis in different sex and relationship between osteoarthritis and age of patients
were determined.
Material and Methods: This study was a non-randomly kuasi clinical trial. Subject
were 20 patients above 50 years of age with signs and symptoms of osteoarthritis from General Hospital
and private practices in Ujung Pandang. Patients were divided into two groups. The first group received
NSAID (Non Steroid Anti Inflammatory Drug) while the second group was provided with NSAID and fisiotherapy.
Koshino Scores was measured at baseline and after two, four and eight weeks of treatment. Score increment
of 20 was good. Data was analyzed with Fischer's exact test. In addition, radiology examination was performed
to determine femorotibial angle (FTA) and degree of joint injury according to Koshino grade.
Results: There were 7 males and 13 females participating in the study. Seventy
percents of subjects were more than 60 years old. Weight and height evaluation showed a significant
overweight. Radiology examination showed that Koshino grade I, II and III were 15%, 45%, and 40%
respectively. In addition, FTA was 176.9 and 174.7 respectively for male and female. Results of
Koshino Knee Score of the first group (NSAID) showed no significant increase of score at the second
week (0%). However, significant increase of Koshino score was seen at the forth week (40%) and
the eight week (50%). On the other hand, the Koshino score in the second group (NSAID + fisiotherapy)
showed a significant increment at the second (40%), forth (90%), and eight (90%) week.
Discussion: The study showed that more cases were found in female compared
to male with the average of age was above 60 years old. The sex ratio in this study was lower
than that in Koshino study, but age average was similar. Also, thee result of femorotibial angle
in female was smaller than that in male. It could also be concluded that fisiotherapy gave more
benefit compared to drug treatment only. Fisiotherapy on knee osteoarthritis may limit degerative
process.
Conclusion: We conclude that efficacy of knee fisiotherapy is better than
drug therapy only. Osteoarthritis is more frequent in female and this may associate with overweight.

MOVEMENT PAIN RELATED HYPERALGESIA IN OSTEOARTHITIS OF THE HANDS
Michael J. Farrell. Joan McMeeken*, Stephen, J. Gibson, Robert D. Helme. National
Ageing Research Inst, PO Box 31, Parkville, VIC, Australia 3052
Objective: Fluctuations in pain provide opportunities to examine the dynamic
character ofhyperalgesia in clinical conditions. The objective of this study was to assess cutaneous
thermal and mechanical pain thresholds (PT) over the thumb following pain provoked by movement
in subjects with osteoarthritis of the hands (OA).
Method: Two groups ofOA subjects were recruited. One group had movement related
pain (MP, n=12). The second group reported no pain in the preceding week (NP, n=12). Thermal (CO;
laser) and mechanical (von Frey filaments) PT were measured over the dorsolatcral aspect of both
thumbs, in both groups prior to, immediately following and 30 min after 5 min of self paced, resisted
thumb movement.
Results: The NP group demonstrated stable PT across the 3 measurement periods.
In the MP group mechanical PT over the moving thumb were lower immediately after movement and
remained lower 30 min later. Thermal PT increased transiently in the non-moving hand in the MP
group.
Conclusions: Movement pain is associated with increased mechanical sensitivity
at a homotopic site and thermal hypoalgesia at a heterotopic site. Distant thermal hypoalgesia
may reflect the influence ofDNIC. It is not readily apparent if movement pain related mechanical
hyperalgesia is due to either peripheral or central sensitisation.
PAIN, DISEASE AND MENTAL HEALTH IN RHEUMATOID ARTHRITIS: A SIX-YEAR OUTCOME
H Heim, Patricia Roche. A Wright, T Oei*, A Klestov**, Depts of Physiotherapy and
Clinical Psychology, Univ of Queensland* and Rheumatology Dept, Royal Brisbane Hospital, Brisbane
4072, Queensland, Australia**
Aim of Investigation: To chart the course and nature of pain, and principle
measures of disease and mental health status in outpatients with progressive rheumatoid arthritis
(RA).
Methods: 120 hospital outpatients with RA for 15.27 years on average, were
assessed at baseline, five (N = 61), and six (N= 59) years later. The MPQ-PRJ was used to calculate
the mean score of pain intensity and two group profiles of pain quality, the Category Utilisation
Profile (CUP) and Average Rank Profile (ARP). Measures of disease and mental health were: ESR,
haemoglobin level, grip strength, morning stiffness, joint tenderness, functional capacity, state
anxiety, depression and learned helplessness. A 6-point scale rated antirheumatic drug therapy.
Results: At baseline, the mean PRI score of 18.10 (±12.93) was portrayed
with 3 subclasses of pressure, dullness, tenderness and the tiring, troublesome and nauseating
qualities of joint pain. Mean scores on each measure of disease and mental health were in the
DMARD medication. Repeated measures analysis showed no significant change in any of measures,
nor in CUP/ARP profiles, over six years.
Conclusions: Under current antirheumatic drug therapy, the average level of joint
pain, disease and negative mental health in outpatients remains moderate over a six year extension of
chronic and active RA. The consistency of the results with a 1997 outcome study of RA suggests their value
as comparative data for future studies of outcome in RA.

Aim of Investigation: Previous research indicated that patients with chronic inflammatory
joint pain respond differently to repetitive painful stimulation. The present study investigated whether
these changes are related to the peripheral or central nervous nociceptive system.
Methods: The pain model used is based on the nociceptive stimulation of the
nasal mucosa with gaseous carbon dioxide; it allows the simultaneous recording of cortical chemo-somatosensory
event-related potentials (CSSERP) and the negative mucosal potential from the surface of the nasal
respiratory epithelium. Twelve patients with rheumatoid arthritis (RA) were compared to healthy
controls matched for age and gender. Responses to both different intensities of painful stimuli
and constant intensities of series of 4 stimuli were analysed.
Results: As in previous studies mentioned above, differences were only found when
repetitive stimulation was performed. While the peripheral nociceptive response did not differ between
groups, CSSERP amplitudes P1N1 and N1P2 were larger in RA patients. Conclusions: This indicates that chronic
inflammatory joint pain produces central nervous changes of nociceptive processing. Acknowledgments: This
research was supported by DFG grant SFB 353 (A7) and by grant P01 DC 00161 from the N1DCD, NIH, USA.

Aim of Investigation: Pain is the most significant symptom in patients with
RA and is most closely related to medication use. However, the precise relationship between pain
and inflammation has not been defined. The aim of this project was to determine the relationship
between pain experience, inflammation and different coping strategies and mood in patients with
RA.
Methods: 20 patients with definite RA were recruited and assessed including:
clinical assessment, ESR, CRP, Visual Analogue Scale (VAS) of global pain, both knees and wrists,
depression, anxiety and coping strategy questionnaires. Labelled neutrophil scintigra-phy of White
blood cell (WBC) (4 hours and 24 hours scans) of both knees and wrists was performed after injection
of mixed WBC labelled with 99m technetium hexamethyl propylene amine oxime "9
tc" HMPAO" using the Gamma camera scmtigraphy. All the patients were assessed on 2 or
3 occasions over a one-year period.
Results: We have found that there is poor correlation between pain and WBC
uptake of the joint (P>.05). Psychological factors including depression, anxiety and pain coping
are more important in predicting pain (P<.05).
Conclusions: This preliminary data supports the concept that psychological
factors may be more important in determining ongoing pain in RA, than inflammation driven nociceptive
inputs. The physiological basis of this will be discussed. Acknowledgments: Supported by Univ
of Manchester and Egyptian Mission Dept as a joint supervision grant.
PAIN IN RHEUMATOID ARTHRITIS: RELATIONSHIP TO MENTAL HEALTH, DISEASE AND DISEASE DURATION
OVER SIX YEARS
Patricia Roche. A. Wright, T. Oei*, A. Klestov, H. Heim**, Depts of Physiotherapy
and Clinical Psychology, Univ of Queensland*, and Rheumatology Dept, Royal Brisbane Hospital,
Brisbane 4072, Queensland, Australia**.
Aim of Investigation: To predict baseline scores of pain intensity from measures
of disease and mental health and a measure of disease duration and to determine the relative predictive
ability of significant variables at baseline, to pain, five and six years later.
Methods: 120 hospital outpatients assessed for joint pain (MPQ-PR1), disease
and mental health status, at baseline, five, and six years later,
Results: At baseline, hierarchical multiple regression revealed that the
set of mental health measures (anxiety, depression and learned helplessness) in Step 1, the set
of disease measures (disease activity, functional loss) in Step 2, and disease duration (Step
3), together accounted for 41% of variance in PRI 1 (p = 0.000). Mental health explained a significant
20% but only the Arthritis Helplessness Index was significantly and independently related to PRI
1. Disease measures together added a significant 18%. Grip strength, joint tenderness and Haemoglobin
were each uniquely related to PRI 1. Disease duration added 2.4%. A Model retaining only those
independent variables sharing unique variance with PRI 1 was used to predict PRI 2 (N = 61) and
PRI 3 (N = 51). The measure of articular tenderness accounted entirely for the 27% variance explained
in PRI 2 (after five years). None of the variables, individually, or in combination, related to
PRI 3. Conclusions: Pain severity in progressive RA is partially explained by principle measures
of disease severity, the sense of helplessness and disease duration. Joint tenderness is the most
reliable predictor of subsequent pain over five years.
PHOTOTHERAPY FOR RHEUMATOID ARTHRITIS
Noriko Satoh. Yoshihiro Ishihara Rehabilitation ofShizuokaken J.A. Nakaizu Supa
Hospital, Nakaizut, Shizuoka, 410-2502, JAPAN
Aim of Investigation: The main treatment for rheumatoid arthritis of the
shoulder joint is conservative therapy because this is a non-weight-bearing joint. Pain decreases
the range of motion and then causes articulator contracture. Conservative therapy includes systematic
and intraarticular administration ofNSAID's, kinesither-apy, and physiotherapy. In the present
study, 1 gave phototherapy to outpatients with this disease and obtained satisfactory result.
Methods: The subjects were 44 outpatients who had RA with shoulder pain lasting
for 6 weeks or more. Ages ranged between 38 and 79 (mean age 60.7). According to Steinbrocker's
classification of RA, 24 and 20 patients were respectively in Class 2 Stage 2 and Class 2 Stage3.
Phototherapy was given using the Super LIZER polarized light apparatus with a wavelength of600-830nm
and an output of ISOOmW. It was delivered to the ipsilateral stellate ganglion region and the
ipsilateral shoulder joint twice a week for 5 weeks After every session, the effect of the treatment
was evaluated on the basis of symptoms, range of motion, and VAS score
Results Among the local symptoms, swelling of the shoulder joint resolved and pain
on motion and joint effusion decreased Among the systemic symptoms, morning stiffness showed a mean decrease
of 20 4 mm in the Class 2 Stage 2 group and 19.4 mm in the Class 2 Stage 3 group. Swelling of other joints
resolved in 19 out of 24 patients from the Class 2 Stage 2 group and in 16 out of 20 patients from the
Class 2 Stage 3 group The erythrocyte sedimentation rate decreased in 14 patients from the former group
and in patients from the latter group The range of motion increased 34 6 ± 0 9 after 10 sessions treatment
in the Class 2 Stage 2 group, 27 9 ± 9 9 degrees in Class 2 Stage 3 group The pain score decreased from
8 0 ± 0 7 before treatment to 2 8 ± 0 7 after treatment in Class 2 Stage 2 group, from 82±07to40±06m Class
2 Stage 3 group
Conclusions In animal studies, phototherapy was clearly more effective for
Stembrocker Stage 2 RA accompanied by inflammation of the synovial membrane and extraarticular
tissues than for Stage 3 and 4 In the present clinical study, its effectiveness was significantly
higher in Stembrocker Stage 2 than in Stage 3 and 4 It appears that phototherapy should be started
early after diagnosis This therapy should be given first as a nonmvasive "synovectomy "
Although its effect is mild, it is useful not only for controlling pain but also for preventing
articular destruction It may also be combined with other treatments

and A V Olesen4, Dept of Rheumatology/Danish Pain Research Center, Univ Hospital of Aarhus,
center for Sensory Motor Interaction, Univ ofAalborg, Dept of Internal Medicine M, Aalborg Hospital, "Dept
of Biostatistics, Aarhus Univ, Denmark
Aim of Investigation Joint pain is the main complaint in rheuma-toid arthritis
(RA) patients The aims were 1) to compare the ability of two different algometers ability to assess
sore joints on the hand, and 2) to correlate the obtained pain detection thresholds (PDT's) to
the traditional measures for pain and disease activity and the demographic data
Methods Forty-one patients with RA according to ACR criteria's were included
Mean age 64±9 4 years Disease duration 14 5 ± 10 years All patients were treated with DMARD's
and/or glucocorti-coids All patients withdraw their analgesic intake 24 hours before the investigation
Pressure algometry was performed using a hand-held device, as well as a computer-controlled pneumatic
device (Aalborg Univ) Disease activity measures according to the American College of Rheumatology
recommendations were obtained.
Results No difference was seen between the two methods in the sensitivity
to assess joint pain, 2) a correlation was found between PDT's and total VAS, finger VAS, swollen/tender
joint count (r between -0 364 and -0 473) There was no correlation between PDT's and acute phase
proteins, x-ray, age and disease duration
Conclusions' A correlation between pressure pain threshold and traditional
pain/disease activity measurements was found in patients with rheumatoid arthritis
SELF-MANAGEMENT OF OSTEOARTHRITIS OF THE HIP OR KNEE IN GENERAL PRACTICE: HOW TO PROMOTE
AND MONITOR TREATMENT ADHERENCE?
Peter HTG Heuts. Onno P van Schayck, Rob A de Bie, Geert-Jan Dinant, Univ of Maastricht,
Dept of General Practice, P OBox 616, 6200 MD Maastricht, The Netherlands
Aim of the investigation To find out whether promoting selfmanagement to patients
with osteoarthntis (OA) of the hip and/or knee is effective in middle-aged patients (40-60 years) The
aim of the presentation is to facilitate discussion about the important issue of monitoring treatment
adherence
Methods In this presentation the design of the randomised clinical trial
will be presented, with empasis on the method of enhancing treatment adherence
Results: From 77 practitioners collaborating in two morbidity registration
networks of the Universities of Maastricht and Nijmegen an aselective sample of patients with
hip and/or knee OA aged 40-60 years are being recruited Practices are randomly assigned to an
experimental or control group in order to avoid contamination of experimental and control treatment
within practices. During the training period (4 months) and the follow-up (24 months) questionnaires(patients,
physicians and therapists) and telephone contacts are used for the promotion as well as the monitoring
of treatment adherence.
Conclusions In setting up this clinical trial the use of questionnaires and
telephone contacts to enhance and monitor treatment adherence is feasable, but further refinement
and development seems worthwile.

Aim of Investigation To investigate whether pain, fatigue, sleep, or inflammation
change during the follicular or luteal phases of a menstrual cycle in premenopausal women with
and without RA.
Methods The descriptive-comparative pilot study measured pain, fatigue, sleep,
and inflammation in both phases of one menstrua] cycle Serum estradiol and progesterone verified menstrua]
phase
Results With a small pilot study, we studied trends as well as statistically significant
results The trend was that women with RA had more pain in both phases (p= 057, p= 055) than controls RA
subjects tended toward greater pain in the luteal (p= 062) than follicular phase Women with RA had more
fatigue (p= 028), increased sleepmess (p= 015), and reduced energy (p= 048) in the luteal than follicular
phase Also in the luteal phase, they had less energy (p= 046) and more awakenings during sleep (p= 013)
than controls Erythrocyte sedimentation rate and C-Reactive Protein tended to be higher for RA subjects
than controls (p= 056- 065) but no differences emerged across phases Interleukin-6 exhibited small, non-significant
differences between phases in RA subjects In the luteal phase, RA subjects tended to have lower cortisol
levels (p= 053) than controls Also in the luteal phase, as cortisol decreased (r = - 6) and estradiol
increased (r = 7), pain increased in women with RA
Conclusions In the luteal phase, women with RA tended toward more pain, less
energy, poorer sleep, and decreased cortisol than controls Pain correlated with increased estradiol
and decreased cortisol Thus, shifting hormone levels may affect RA symptoms in cycling women.
Due to small sample size, this study must be replicated.

Aim: To use intra-articular phenol for the treatment of chronic pain secondary
to severe degenerative Joint disease in patients in whom joint replacement was contra-indicated
Method Phenol 10% in 60% meglumine lothalamate (Conray 280) was injected
into the painful joint. The position of the needle and injection into the joint space was confirmed
using an image intensi-fier.
Results. Three patients underwent intra-articular phenol injection They were
all elderly and had multisystem diseases associated with advanced degeneration of one or more
joints. None of the patients was suitable for joint replacement The pain was not relieved by appropriate
conventional analgesics and prevented adequate nursing care. Three shoulders (one of the patients
had bilateral shoulder disease) and one hip joint were injected. Each shoulder was injected with
5ml of Conray 280 mixed with 10ml of 0.5% bupivi-came The hip joint was injected with 10ml of
Conray 280 All three patients obtained sustained pain relief which allowed the patients to receive
full nursing care
Conclusions Phenol has a limited but important role in the management of
pain In some patients not suitable for joint replacement it can be used mtraarticularly to provide
effective, long-term anal-gesia for pain secondary to severe degenerative joint disease We believe
this is the first reported use of phenol in the shoulder and hip joints.
ANTERIOR COMPARTMENT KNEE PAIN

Aim. To establish the nature, diagnostic distinctions and treatment outcomes,
of a range of refractory anterior compartment knee pains.
Method: Data was obtained from a retrospective analysis of a sequential senes
of 109 cases collected over 8 years
Results: Different groups were identified as follows
Patello-femoral pain. comprised 35% of cases, with diffuse, aching, constant pain,
patellar tenderness and cutaneous hyperalge-sia about the front of the knee All had minor injury
but 70% have a prior migraine, fibromyalgia, irritable bowel or other sensitisation pain disorder.
Treatment for these was successful, using tncyclics, clonidine, oral analgesics, tens and rhythmical
exercising. Femoral nerve blocks were needed for 20% of cases, but in all, 10% have needed repeat
treatments.
Infra-patellar/saphenous nerve injury was seen in 18 of this senes, showing local
irritation, usually within a scar Drug treatment to lessen secondary hyperalgesia preceded local/steroid
block, 16 gaining complete cure.
Complex Regional Pain Syndrome occurred in 15% of post injury patients. Features
included diffuse sharp/burning pain, hy-peralgesia/allodynia, colour/temp changes, swelling, weakness,
wasting, textural skin changes, 5 hemorrhagic joint effusions, and infections which proceeded
to amputation in two cases. Aggressive combined drug treatments, including gabapentm and sometimes
opioids, were applied in conjunction with exercising, cognitive therapies and sensory stimulation
as hyperalgesia regressed One third required femoral or epidural block to obtain pain suppression
Four patients have not improved
Mechanical pain after trauma or surgery was the dominant cause of pain in twelve
patients, but depression or abnormal illness behaviour were seen as compounding features Conservative
cares generally gave 50% relief.
Mixed trauma/nerve injury causing long term sensitisation and functional loss was
evident in another 10% who were difficult to treat Inflammatory arthropathy with pencapsular swelling,
effusion and tenderness was a common feature Treatment was less successful than for other knee
pains and may require more aggressive and combined treatments, including early joint replacement
