ABSTRACT
Objective To explore the effect of the rehabilitation self-efficacy of patient with total knee arthroplasty on the first time of ambulation after operation.Methods Totally 110 patients undergoing total knee arthroplasty were recruited,they were investigated with self-designed general information and disease situation questionnaire and recorded the first time of ambulation.The self-efficacy was measured by the Self-Efficacy for Rehabilitation outcome scale(SER).Results The earliest time of ambulation was 7.5 hours after surgery.The latest time of ambulation was 54.0 hours after surgery.The median time of the first ambulation was 46.0 h.The mean score of self-efficacy for rehabilitation therapy exercises was (28.58 ± 9.18) points,and the mean score of self-efficacy in overcoming barriers was (43.07 ± 11.04) points,and the mean score of SER was (71.65 ± 18.47) points.The total score of self-efficacy for rehabilitation therapy exercises,self-efficacy in overcoming barriers,and the score of SER were negatively correlated with the first time of ambulation (r=-0.442,-0.299,-0.399,P＜ 0.01).The self-efficacy of rehabilitation was one of the influencing factors of patient's first time of ambulation(P ＜ 0.05),which explained 9.7％ of total variance of early ambulation of patients with total knee arthroplasty.Conclusions The self-efficacy of rehabilitation after total knee arthroplasty was significantly correlated with the first time of ambulation,and the higher self-efficacy of rehabilitation,the earlier the first time of ambulation.The self-efficacy of rehabilitation was one of the important factors that affect the first time of the patient's ambulation after total knee arthroplasty.
