The purpose of this study was to investigate the relationships among pain, gait, activities of daily living (ADL) and muscle strength per body weight in patients with osteoarthritis (OA) of the knee joint. Subjects were 37 patients with OA of both unilateral and bilateral cases (7 men and 30 women, mean age 64.1±10.4 years). Isometric muscle strength per body weight of Quadriceps (Q%BW) and Hamstrings (H%BW) were measured with the Musculater GT-30 and the ratio of Q%BW to H%BW (Q/H ratio) was also calculated. Q% BW and Q/H ratio were significantly different with pain, but H%BW was not significantly different with pain. Only Q%BW of bilateral knee was significantly different with gait and ADL, H%BW and Q/H ratio of bilateral knee were not significantly different with gait and ADL, and Q%BW, H%BW and Q/H ratio of unilateral knee were-not significantly different with gait and ADL. Our results shoowed that Q%BW might be useful to evaluate pain, gait and ADL in patients with OA of bilateral knee joints.
