Supervised fitness walking in patients with osteoarthritis of the knee. A randomized, controlled trial.
OBJECTIVE To assess the effect of a program of supervised fitness walking and patient education on functional status , pain , and use of medication in patients with osteoarthritis of the knee . DESIGN An 8-week r and omized , controlled trial . SETTING Inpatient and outpatient services of an orthopedic hospital in an academic medical center . PATIENTS A total of 102 patients with a documented diagnosis of primary osteoarthritis of one or both knees participated in the study . Data were obtained on 47 of 51 intervention patients and 45 of 51 control patients . INTERVENTIONS An 8-week program of supervised fitness walking and patient education or st and ard routine medical care . MEASUREMENTS Patients were evaluated and outcomes assessed before and after the intervention using a 6-minute test of walking distance and scores on the physical activity , arthritis impact , pain , and medication subscales of the Arthritis Impact Measurement Scale ( AIMS ) . RESULTS Patients r and omly assigned to the walking program had a 70-meter increase in walking distance relative to their baseline assessment , which represents an improvement of 18.4 % ( 95 % Cl , 9.8 % to 27.0 % ) . In contrast , controls showed a 17-meter decrease in walking distance relative to their baseline assessment ( P less than 0.001 ) . Improvements in functional status as measured by the AIMS physical activity subscale were also observed in the walking group but not in the control group ( P less than 0.001 ) ; patients assigned to the walking program improved 39 % ( Cl , 15.6 % to 60.4 % ) . Although changes in scores on the arthritis impact subscale were similar in the two groups ( P = 0.093 ) , the walking group experienced a decrease in arthritis pain of 27 % ( Cl , 9.6 % to 41.4 % ) ( P = 0.003 ) . Medication use was less frequent in the walking group than in the control group at the post-test ( P = 0.08 ) . CONCLUSIONS A program of supervised fitness walking and patient education can improve functional status without worsening pain or exacerbating arthritis-related symptoms in patients with osteoarthritis of the knee
