PURPOSE The purpose of this study was to identify factors related to walking efficiency in the early postoperative period of total hip arthroplasty (THA). METHODS The subjects of this study were 18 women who had undergone unilateral THA 4 weeks before and 18 healthy women as control. Using a force plate and a 3-D motion analyser, we measured: 1) gait speed, stride length, cadence; 2) centre of mass displacement in the three directions; 3) asymmetry of the centre of mass movement in vertical… CONTINUE READING
