Development and preliminary evaluation of a tele-rehabilitation exercise system using computer-generated animation

Area of Science:

• Rehabilitation Medicine
• Digital Health
• Exercise Physiology

Background:

• Tele-rehabilitation offers a promising avenue for remote patient care.
• Computer-generated animation can enhance engagement in exercise programs.
• Assessing the safety and acceptability of novel digital health interventions is crucial.

Purpose of the Study:

• To evaluate the safety and user acceptability of a novel tele-rehabilitation exercise system.
• To assess the system's impact on physiological parameters and user motivation.
• To identify areas for improvement in digital therapeutic exercise delivery.

Main Methods:

• A convenience sample of 38 diverse individuals (healthy and patient populations) participated in safety assessments.
• A separate group of 18 healthy older adults evaluated treatment acceptability.
• Safety was measured by heart rate, oxygen saturation, and fall incidence; acceptability was assessed via a Likert scale questionnaire.

Main Results:

• The tele-rehabilitation system demonstrated safety, with no reported falls and acceptable physiological changes (heart rate, SpO2).
• User acceptability was generally positive, with a high desire to continue the exercises (2.71±0.46).
• Exercise intensity adequacy received the lowest score (1.29±0.57), indicating a need for adjustment.

Conclusions:

• The animated tele-rehabilitation system is safe and motivates users to continue.
• Individualized adjustment of exercise intensity is recommended for future system development.
• This technology holds potential for effective remote physical therapy interventions.
