Summary

Total knee arthroplasty (TKA) is the most common joint surgery. Post-operative exercises are prescribed post-surgery to regain full range of motion and often require personal aid. While existing analog physiotherapy methods aid recovery, we explored opportunities to enhance physical therapy using non-visual augmented reality (AR).

Guiding questions:

• "How can non-visual AR aid physical therapy task guidance for post-surgery recovery?"

• "How can non-visual AR support physiotherapists in their roles?"

Our solution:

A novel use of non-visual AR in TKA recovery physiotherapy. It aims to increase the efficacy and efficiency of rehabilitation by substituting conventional instruments with AR solutions that use auditory input, as well as AI and large language models (LLM) for activities such as filing reports and taking session notes.

The impact:

This app reduces administrative load on therapists, enabling patients to conduct home therapy sessions more independently, in addition to improving exercise precision and reducing recovery downtime. By combining AR technology with user-centered healthcare, our project demonstrates a novel opportunity for non-visual AR to enhance patient recovery.
