Abstract

Physical activity outcomes are poor following total knee arthroplasty (TKA). The purpose was to evaluate feasibility of a physical activity feedback intervention for patients after TKA. Participants completing conventional TKA rehabilitation were randomized to a physical activity feedback (PAF; n = 22) or control (CTL; n = 23) group. The PAF intervention included real-time activity feedback, weekly action planning, and monthly group support meetings (12 weeks). The CTL group received attention control education. Feasibility was assessed using retention, adherence, dose goal attainment, and responsiveness with pre- and postintervention testing. The PAF group had 100% retention, 92% adherence (frequency of feedback use), and 65% dose goal attainment (frequency of meeting goals). The PAF group average daily step count increased from 5,754 (2,714) (pre) to 6,917 (3,445) steps/day (post). This study describes a feasible intervention to use as an adjunct to conventional rehabilitation for people with TKA.
