This project is a bit close to my heart and I started this out as a way to help my mom who recently had a knee surgery. While the physiotherapy did help at start, She often needed close guidance from the therapist to aid her during rehabilitation. The therapist was rather hard to get hold often due to amount of patients he had to deal with for the same problem.
I wanted to do something which could provide real assistance and insight into her joint condition in a easily understandable manner and also help the physiotherapist increase both his efficiency and standard of care in a home setting. I was suprised to find no solution to this problem in the market which consists of a wide spectrum of fitness monitoring wearables. I hope to fix that with this project and try to illustrate the untapped market of assistive wearable sensors for chronic care. The features I decided to include from start was joint angle monitoring, gait pattern sensing and the acoustic profile sensing of the knee.
I conceptualized a home monitoring system which would allow the patient to track their progress with remote guidance from the physiotherapist. With less than 35% of the outpatients adhering to the training regimen suggested, It is important to have a reinforcement system to evaluate patient compliance and provide them motivation to continue.
Here's a sketch of the initial concept I came up with.
