Plataforma para monitoramento da recuperação de movimentos da mão

Abstract

Nowadays, over motor rehabilitation processes, the evaluations of the health professionals are often qualitative, using touch techniques and visual analysis, making it relative and subjective from professional to professional and such fact in the public and private health system, reverts to longer time and more expensive than expected. To make the quantitative evaluation process in the evolution of the patient, it is necessary to use an electronically instrumented platform which provides the information of the amount of movement and muscle analysis of the limb in question in a suitable format presented to physical or occupational therapist. In this context, this work was intended to develop a platform for monitoring the recovery of basic hand movements, measuring the amount of movement through accelerometer and gyroscope data and muscle analysis using the surface electromyography technique. The system analyzes and compares the measurements taken with the patient's own data, in order to assist the professional with useful information about the evolution of the rehabilitation process. The platform presented positive and expected results according to the literature review carried out, being able to estimate the range of chosen movements with an accuracy of ±0.5° and analyze the RMS value of the sEMG signal, reflecting the number of active motor units related to the movement, achieving the proposed objectives. However, for clinical applications to be performed by health professionals, it is still necessary to validate the sampling protocols, make the hardware flexible for greater flexibility and user comfort, in addition to measuring the estimated values generated by the platform in order to obtain greater accuracy in the informations.
