A Nurse-Led App-Based Home Exercise Program After Total Knee Arthroplasty: A Quasi-Experimental Study.

ABSTRACT

PURPOSE: Reduced activity because of pain is a major health issue associated with total knee arthroplasty. This study evaluated the effectiveness of a nurse-led app-based home exercise program for patients who underwent total knee arthroplasty. METHODS: A nonequivalent control group of pretest-posttest design was used. Data from 45 patients were collected. The control group received individualized face-to-face exercise education, whereas the experimental group received training on the use of app-based home exercise education, including exercise videos and app push notifications to encourage exercise after discharge. Pain, range of motion, exercise self-efficacy, and quality of life were measured at baseline and 3 and 12 weeks after surgery. Nursing care satisfaction was evaluated 12 weeks after surgery. RESULTS: There were significant overall reductions in pain intensity ( p = .001), improvements in limited range of motion ( p < .001), and increases in exercise self-efficacy ( p = .034) and quality of life ( p = .033) in the experimental group ( n = 22) compared with those in the control group ( n = 23). Nursing care satisfaction was significantly higher in the experimental group than in the control group ( p < .001). CONCLUSIONS: Rehabilitation nurses can offer app-based home exercise education with push notifications to alleviate pain, enhance range of motion, improve exercise self-efficacy, and increase nursing care satisfaction for patients who have had a knee arthroplasty.
