Technological Architecture with Low Cost Sensors to Improve Physical Therapy Monitoring
In this article, we propose a wireless monitoring solution for gait parameters using low-cost sensors in the physical rehabilitation of patients with gait disorders. This solution consists of infrared speed sensors (IRSS), force sensor (FRS) and microcontrollers placed in a walker. These sensors can capture the distribution of pressure on the walker's handle and the speed of the steps during rehabilitation. The proposal allows to improve the session times of traditional physiotherapy through a mobile application that performs the monitoring controlled by a health specialist in real time. The proposed solution is made up of 4 stages: 1. Obtaining gear parameters, 2. Data transmission, 3. Data in the cloud and 4. Data collection and processing. The project was validated with ten patients from a physical rehabilitation center in Lima, Peru. Preliminary results revealed a significant reduction in the rehabilitation session from 25 to 5.2 minutes.
