A Device for Prehabilitation of Total Knee Replacement Surgery (Slider): Usability Study

Area of Science:

• Orthopedics
• Digital Health
• Rehabilitation Technology

Background:

• Prehabilitation is crucial for knee replacement surgery, but demand exceeds resources, exacerbated by the COVID-19 pandemic.
• Digital solutions like apps and wearables are emerging but face engagement and usability challenges.
• This study explored a novel low-contact, gamified device for prehabilitation exercises.

Purpose of the Study:

• To evaluate the practicality and user-friendliness of a new physiotherapy device (Slider).
• To assess the device's ability to monitor exercises without skin contact.
• To gauge patient acceptance and suitability for pre-surgery physiotherapy.

Main Methods:

• 17 patients awaiting knee replacement surgery participated.
• The device was used for a 2-week period.
• Usability and acceptability were assessed via questionnaire.

Main Results:

• All 17 participants completed the study.
• 76% found the device intuitive and easy to use.
• 94% were satisfied with its ability to meet pre-surgery needs, and 100% were willing to continue use.

Conclusions:

• The device is a feasible option for independent, in-home pre-surgery physiotherapy.
• Further validation with larger, diverse cohorts is recommended.
• The technology offers a promising alternative to traditional rehabilitation methods.
