Using Non-Traditional Interfaces to Support Physical Therapy for Knee Strengthening

Area of Science:

• Biomedical Engineering
• Rehabilitation Science
• Human-Computer Interaction

Background:

• Knee rehabilitation exercises can be monotonous, leading to poor patient adherence and hindering recovery.
• Current methods for monitoring physical therapy exercise performance are often subjective and lack quantitative validation.
• Accurate assessment of patient progress is crucial for effective physical therapy and injury recovery.

Purpose of the Study:

• To develop and evaluate a wearable technology system for monitoring knee physical therapy exercises.
• To enhance patient engagement and adherence in daily rehabilitation routines through a gamified interface.
• To provide physical therapists with objective, quantitative data on patient performance and progress.

Main Methods:

• A wearable sensor device was developed to capture limb movement data during rehabilitation exercises.
• Data from the wearable device was transmitted wirelessly to a mobile application.
• The mobile application featured a game-based user interface designed to motivate patients and align with physical therapy protocols.

Main Results:

• The developed system significantly increased daily user engagement in prescribed rehabilitation exercises.
• The gamified approach successfully motivated patients to adhere to their physical therapy regimens.
• The system provided therapists with quantitative performance metrics, aiding in progress assessment.

Conclusions:

• Wearable technology integrated with gamification offers a promising solution to improve adherence in knee physical therapy.
• This system enhances the patient experience by making rehabilitation exercises more interactive and enjoyable.
• Objective data collection through this system supports more effective and personalized physical therapy interventions.
