To develop a combined program of Tai Chi and exercise rehabilitation for total hip arthroplasty and evaluate its effect on functional rehabilitation.

A total of 80 patients undergoing primary total hip arthroplasty (posterior lateral approach) were randomly divided into a control group (n=40) and an experimental group (n=40). The control group received a routine rehabilitation training program, while the experimental group received the combined program of Tai Chi and exercise rehabilitation for total hip arthroplasty, constructed by the research group based on the Delphi method, for a total of 24 weeks. Before and after treatment, the BIODEX balance test system, timed up and go test (TUGT), Harris hip joint function assessment scale, modified fall efficacy energy scale (MFES), and SF-36 quality of life comprehensive scale were used for evaluation.

A total of 7 cases dropped off, 3 in the control group and 4 in the experimental group. Thus, data from 73 patients (control group: n=37; experimental group: n=36) were analyzed. After treatment, both groups showed significant improvement in BIODEX balance function score, TUGT score, Harris hip function score, MFES score, and SF-36 comprehensive quality of life score (P<0.05), with the experimental group showing significantly better results than the control group (P<0.05).

The combined program of Tai Chi and exercise rehabilitation after total hip arthroplasty based on Delphi method is scientific and feasible. This program can effectively improve the hip joint function, balance function and walking ability in patients undergoing total hip arthroplasty, reduce fear of falling, and improve the quality of life.
