Abstract
The main issue with stroke patients is that patients lose their ability to balance due to the loss of the ability to control the functions of the trunk and leg muscles and the loss of sensation. In rehabilitation of patients with balance training, patients receive voice feedback based on physiotherapists’ observations. This may lack accuracy and quantitative measures. Therefore, the purpose of the research project is to develop a balance training device with visual feedback. It consists of 2 sets: a sitting-balance feedback set and a standing-balance feedback set. Two load cells were installed in the sitting-balance feedback set. They were used to measure weight and monitor sitting balance. Four load cells were used in the standing-balance feedback set in order to detect foot bearing for both foot tip and heel. The weight values were sent to the display unit via RS485 communication. The display unit received weight values and displayed feedback on screen. This helped patients adjust themselves back to balance by observing visual feedback on the screen. The experimental results showed that the developed apparatus functioned properly as designed. The participants perceived the weight bearing visually during training. Moreover, after training, physical therapists obtained the training summary for analysis or comparison of performance before and after training.
