Abstract: To study the effect of a program of physical therapy,40 subjects with total hip replacement for femoral neck fracture were randomized into rehabilitation and control groups.The program included ROM exercises,low resistance exercises of hip abductors and ADL exercises.Muscle strength of hip abductors were measured by Kendall's Muscle Testing and Function,hip ROM,functional ability and pain were evaluated by Harris Hip score on the lst and 3rd month after surgery.Statistical analysis with t test was used for comparing Harris Hip scores.The result shows that muscle strength and hip function were improved significantly in rehabilitation group (p<0.05).That means the program is effective in long term after hip replacement.

Key words: total hip replacement, rehabilitation treatment
