We investigated the role of an evidence-based integrated group rehabilitation
program on the treatment of patients with knee osteoarthritis (KOA). This was a
two-group, randomized controlled, 8 wk trial with 41 patients with moderate to
very severe KOA. Patients were assigned to an intervention group (IG) or control
group (CG). After both groups had received a self-management education program,
IG participants underwent a rehabilitation program, including educational aspects
about KOA followed by exercises. CG participants received only general health
orientation about KOA during this period. The outcome measures were the Lequesne
algofunctional index; 36-Item Short Form Health Survey (SF-36); and chair-stand,
sit-and-reach, timed up-and-go, and 6-minute walk tests. Analysis of covariance
revealed significant postintervention improvements of IG participants compared
with CG participants (p < 0.05) on Lequesne total score and pain and function
subdomains; SF-36 physical function, role physical, bodily pain, general health,
vitality, and role emotional subdomains; and performance assessed by chair-stand,
timed up-and-go, and 6-minute walk tests. Focusing on the primary outcome
(Lequesne total score), the mean +/- standard deviation after 8 wk was 5.50 +/-
2.98 for the IG and 7.87 +/- 3.48 for the CG (p = 0.009). The corresponding
effect size (partial eta squared with 90% confidence interval) was 0.23
(0.04-0.42), indicating a large effect. The presented rehabilitation program
reduced pain and improved quality of life and function in patients with KOA.
