Real-Time Digital Feedback for Exercise Therapy of Lower Extremity Functional Deficits: A Mixed Methods Study of User Requirements

Stud Health Technol Inform. 2023 May 2:301:108-114. doi: 10.3233/SHTI230021.

Abstract

Background: Relearning physiological movement patterns is a key factor to success in the treatment of functional deficits. Motivation to train sustainably is essential for successful motor re-education and can be promoted by instrumentally supported real-time feedback.

Objectives: Study findings should improve the understanding of real-time feedback visualization for exercises targeting the lower extremities.

Methods: A mixed-methods survey on recognition, comprehensibility, color scheme and shape of six real-time feedback prototype visualizations was conducted among three user groups (physicians, physiotherapists, and patients).

Results: The mean correct recognition of body regions visualized in the feedback was 55 %, ranging from 29 % to 74 %. Comprehensibility, color scheme and shape were best received for feedback with clear visual guidance, sympathetic and motivating color schemes and abstract visualizations of body regions.

Conclusion: Insights were gathered for the design, optimization, and customization of visualizations to develop a real-time feedback prototype.
