Studies on preoperative physiotherapy with THA

Study	Level of evidence	Number of patients	Assessment points	Conclusion
Wang et al. [62] (2002)	I	48	Assessed effect of preoperative physical therapy on gait after THA	8-week preoperative physical therapy showed faster improvement in cadence, stride length, greater mean walking distance and gait velocity
Gilbey et al. [18] (2003)	I	76	Assessed the effect of preoperative physical therapy on strength of thigh flexors, extensors and abductors, and range of motion of the hip after THA	Exercise group did significantly better in both parameters
Gocen et al. [20] (2004)	I	60	Assessed the functional outcome after THA with preoperative physical therapy	8-week preoperative physical therapy had no effect on the Harris Hip Score, VAS pain score, and range of abduction with a followup up to 2 years
Rooks et al. [56] (2006)	I	63	Assessed the functional outcome and frequency of home discharge after THA with preoperative therapy	6-week preoperative physical therapy had no effect on WOMAC and SF-36 scores up to 26 weeks followup, but the frequency of home discharges was higher for the exercise group
