Effects of using activity diary for goal setting in occupational therapy on reducing pain and improving psychological and physical performance in patients after total knee arthroplasty: A non-randomised controlled study.

Abstract

BackgroundPsychological factors have been reported to affect chronic pain and may lead to inactivity after total knee arthroplasty. This study aimed to determine whether the use of an activity diary for goal setting during occupational therapy would reduce pain, and improve psychological and physical performance in patients after total knee arthroplasty.MethodsA total of 41 total knee arthroplasty participants from two cohorts were recruited in the study and allocated by convenience to either the experimental group using an activity diary (n = 20) or the control group (n = 21). Occupational therapy intervention (1–2 weeks postoperatively) to promote goal achievement was performed in both groups, and self-monitoring was performed in the diary group by using the activity diary. The outcome indices were Canadian Occupational Performance Measure, pain (resting pain, walking pain), pain catastrophizing (rumination, helplessness, and magnification), anxiety, depression, pain self-efficacy, and physical activity level. Data were evaluated by using analysis of variance analyses with post hoc tests.ResultsA time-by-group interaction emerged for Canadian Occupational Performance Measure, walking pain, pain catastrophizing, anxiety, depression, and physical activity level (p < 0.05), both favouring the diary group. The diary group also showed greater improvement in Canadian Occupational Performance Measure, walking pain, anxiety, and physical activity levels at four weeks postoperatively, compared to the control group (p < 0.05).ConclusionThe use of the activity diary in this study increased occupational therapy effectiveness, reduced patients’ pain, and prevented a decline in physical performance. We believe that the use of an activity diary is an effective and feasible addition for total knee arthroplasty patients.
