OBJECTIVE. The aim of this study was to examine physical performance
in women with fibromyalgia (FM) using methods that are easy to
use in clinical settings and to compare our findings with
published norms or a healthy comparison group.
Measures of shoulder pain and range-of-motion, isometric
shoulder endurance, neck rotation, leg strength, hand grip
strength, back flexibility, 6-minute walk distance, and
symptom duration were completed on 97 subjects with FM. The
comparison group was 30 age-matched healthy women.
The FM group had significantly lower physical functioning
scores on all variables when compared to the healthy group or
published norms. When pain at rest was controlled, pain on
motion was the most significant predictor of variance in
shoulder range of motion, whereas range of motion was the most
significant predictor of right shoulder endurance and grip
strength of both hands.
CONCLUSIONS. Women with FM are
markedly below average in physical performance abilities when
measured by clinical tests.
