Abstract
The benefits of isometric strengthening exercises (ISEs) are compromised when patient teaching on ISEs is delayed and/or ineffectively delivered due to healthcare resources constraint, especially when health resources are stretched, as occurred during the COVID-19 pandemic. This study aims to examine the effect of a video-assisted ISE program on pain and muscle strength of patients following surgical stabilization of lower limb fracture. A quasi-experimental study with repeated measures was employed. Primary study outcomes were assessed using the Brief Pain Inventory and Manual Muscle Test. Effects over time were analyzed using generalized estimating equations. In comparison with usual care group ( n = 32), the intervention group ( n = 33) showed better pain reduction over time ( p < .001, effect size [ES] = 0.39–1.77) and muscle strength preservation ( p < .05; ES = 0.8–0.9). Patient acceptance of the intervention was favorable. Integration of video clips into patient teaching on ISEs is potentially beneficial in managing pain and muscle strength; it can be easily deployed to aid early ISE initiation.
