Si. Bekkelund et al., QUANTIFIED NEUROLOGICAL EXAMINATION WITH EMPHASIS ON MOTOR AND SENSORY FUNCTIONS IN PATIENTS WITH RHEUMATOID-ARTHRITIS AND CONTROLS, British journal of rheumatology, 35(11), 1996, pp. 1116-1121
A controlled study of quantified clinical neurological examination, in
cluding psychophysical assessment of sensory thresholds, in patients w
ith rheumatoid arthritis (RA) was carried out. Fifty-five women with s
eropositive RE living in North Norway and 83 healthy controls underwen
t clinical neurological examination quantified by neurological symptom
score (NSS) and neurological deficit score (NDS). Vibration threshold
(VT), warm-cold detection threshold (limen) as well as heat pain dete
ction threshold (HPDT) were performed to evaluate afferent myelinated
and unmyelinated fibre functions. Higher scores on NSS and NDS were se
en in RA patients compared with the controls. Higher index finger and
big toe VT was demonstrated in the patients, while results from warm-c
old limen and HPDT were not significantly different in the two groups.
Among the disease-related variables, the most prominent finding was a
positive association of index finger VT with disease duration in the
patients (P = 0.01). Maximum walking time (15 m) was a significant pre
dictor of big toe VT in the patient group (P = 0.0001). This study sug
gests impaired peripheral nerve function in afferent myelinated fibres
. However, involvement of dorsal column fibres cannot be excluded, alt
hough patients with radiological atlantoaxial subluxation were not inc
luded in this study.
