The purpose of this study was to investigate the functional changes of the vastus medialis while the neuromuscular electrical stimulation(NMES) was performed in elderly women with knee osteoarthritis. The subjects of this study were 30 women who were diagnosed degenerative arthritis, 15 in the experimental group and 15 in the control group. The experimental group performed conventional physical therapy and neuromuscular electrical stimulation, and the control group received only conventional physical therapy, five times per week for four weeks. Outcome measures were assessed before and after 4weeks using the VAS(pain), quadriceps femoris strength, thigh circumference, and Q-angle. The data of the quadriceps femoris strength and thigh circumference were significantly increased in experimental group(p<0.05). The data the pain was significantly decreased in both the two groups(p<0.05). There were statistically significant differences in quadriceps femoris strength and thigh circumference between the two groups(p<0.05). As the result, the application of neuromuscular electrical stimulation of the vastus medialis could be more effective for decrease pain and improving muscle function in patients with knee osteoarthritis.
