Mj. Bell et al., A RANDOMIZED CONTROLLED TRIAL TO EVALUATE THE EFFICACY OF COMMUNITY-BASED PHYSICAL THERAPY IN THE TREATMENT OF PEOPLE WITH RHEUMATOID-ARTHRITIS, Journal of rheumatology, 25(2), 1998, pp. 231-237
Objective. To evaluate the short term efficacy of a community based ph
ysical therapy (PT) program for people with rheumatoid arthritis (RA)
through a single blind randomized controlled trial. Methods. Adults wi
th active RA were referred by their physician for community based PT.
Participants were randomized to either an immediate intervention group
[experimental group (EG)] or a wait list control group (CG). The inte
rvention was a standardized program of education and exercise consisti
ng of at least 4 visits or 3 h of PT over 6 weeks. Baseline, 6, and 12
week assess ments were by a blinded independent assessor. The primary
outcome instrument was the Stanford Arthritis Self-Efficacy Scale (SE
S) and secondary outcome measures included the ACREU Rheumatoid Arthri
tis Knowledge Questionnaire (KQ) and visual analog scale for pain (VAS
). Duration of morning stiffness, grip strength, and tender joint coun
t were also collected at each assessment. Outcome analysis was conduct
ed using analysis of variance. Results, Of 150 eligible and randomized
participants, 127 completed the study according to protocol. Baseline
analysis showed no differences between the EG and CG for demographics
, disease status, or other characteristics. At the 6 week assessment,
primary outcome analysis for those who completed the protocol identifi
ed a mean change (improvement) of 13.5% in the EG and 5.8% in the CG,
representing a 7.7% difference in change scores between the 2 groups [
F(1,121) = 6.03; p = 0.015]. A statistically significant difference in
change scores was also identified for the KQ [F(1,120) = 6.67; p = 0.
011], but not for the VAS. Disease status measures did not change, exc
ept for duration of morning stiffness, which improved by 68.8 min in t
he EG and 8.3 min in the CG (F(1,121) = 4.50; p = 0.036]. Conclusion.
Four hours of a community based PT intervention delivered over 6 weeks
significantly improved self-efficacy, disease management knowledge an
d morning stiffness in people with RA.
