Summary
Older adults undergoing total knee replacement (TKR) can achieve rehabilitation goals with exergames, which offer higher movement volume and intensity without increasing pain. These findings suggest exergames are a viable option for TKR rehabilitation.
Area of Science:
- Biomedical Engineering
- Rehabilitation Science
- Kinesiology
Background:
- Limited understanding exists regarding kinematic goal achievement in older adults during exergames versus conventional exercises post-total knee replacement (TKR).
- Comparing movement characteristics, perceived exertion, and pain between exergames and traditional exercises is crucial for optimizing TKR rehabilitation.
Purpose of the Study:
- To describe movement characteristics during custom exergames and conventional exercises in post-TKR patients.
- To compare kinematic goals, perceived exertion, and knee pain between exergames and conventional exercises.
- To assess the suitability of exergames for TKR rehabilitation.
Main Methods:
- Seven patients post-TKR participated in a single-visit laboratory session.
- 2D motion analysis and force plates evaluated movement volume, range, and intensity during knee extension-flexion and weight-shifting exergames and conventional exercises.
- Borg Rating of Perceived Exertion and Visual Analog Scale assessed perceived exertion and knee pain.
Main Results:
- Exergames demonstrated higher movement volume and intensity compared to conventional exercises.
- Individual knee range of motion goals were met with both exergames and conventional exercises, particularly in extension.
- Perceived exertion and knee pain levels were comparable between exergames and conventional exercises.
Conclusions:
- Custom exergames facilitate appropriate movement characteristics for post-TKR rehabilitation without increased stress or pain.
- Exergames may offer a viable alternative or supplement to conventional therapy for TKR patients, with potential for higher movement volume and intensity.
- Further research into the effectiveness and wider availability of exergames is recommended for physical therapists.
