Rehabilitation of patients with osteoarthritis (OA) is typically based on home exercise programs. These programs are believed to benefit patients and have been shown to qualitatively improve strength. The purpose of the present study was to quantitate the effects of a three-month home exercise program on muscle function and functional capacity. Nineteen patients with OA of the knee began the program, but only nine completed it. The subjects were aged 65 to 75 years and weighed 86.16 +/- 12.93kg. The subjects initially had significantly reduced muscle and functional capacity. Maximal isometric strength of knee extension increased significantly at a knee angle of 43 degrees for hip angles of 120 degrees, 90 degrees, 60 degrees, and 150 degrees (35%); however, it failed to increase at longer muscle lengths. There were no significant improvements in hamstring strength. Maximal speed of contraction against all resistances improved significantly after three months of exercise (40%). Muscle endurance of the quadriceps did not improve significantly. Functional capacity did not improve significantly after the program. These data fail to demonstrate improved function in OA patients after home exercise, in spite of improved quadriceps strength and speed. The absence of improvement in function may reflect the failures of strength, at the longer muscle lengths, and endurance to improve.
