Investigation and development of hand tremor controlling device

Current therapies for hand disease tremors are medication and surgery, which have demonstrated different degrees of efficacy with the risk of serious side effects. Wearable tremor suppression devices have proven that the usage of mechanical and electronic devices has produced positive outcomes. There are a variety of tremor suppression devices available. In this study, patients with hand tremor disorders were evaluated and validated for a wearable tremor arm prototype. A motor, hand brace, microprocessor, and LCD are the main features for this system. Two preliminary tests were carried out to evaluate the proposed device’s effectiveness in suppressing tremor motion and following voluntary movements. The results of the study show that the patients are able to control their hand tremors using a microcontroller and a four-speed motor. Participants are chosen with age range from 38 to 60 years old and included both men and women. Both evaluations yielded satisfactory findings for the proposed device’s validation. However, the suggested methods require more human trials to improve its performance.
