Abstract
Purpose:
Power orthoses, due to their characteristics, can greatly assist in the recovery and improvement of people with problems in hand function. The purpose of this study was to review the glove-like power hand orthoses that were designed to practice, assist and improve performance in patients with weak or paralyzed hands.
Methods:
PubMed, Scopus, ISI web of sciences and IEEE databases were searched from 2000 to 2019. The keywords used to search were selected based on the PICO strategy. By using the introduced keywords, 605 articles were obtained. After the final evaluation, 12 articles were selected. Criteria for the study included: design and development of glove-like power orthoses, use of orthoses for treatment, rehabilitation and improvement of hand function, use for people with weakness or paralysis of the hand muscles due to central nervous system disorder.
Results:
The study showed that of the 12 introduced orthoses, 10 orthoses used electric motors to generate propulsion, and 2 orthoses benefited from the pneumatic system. Regarding force transmission systems, most of these orthoses use cable transmission systems. What makes these orthoses even more differentiated is the control system, which can be referred to as positional signals, electrical muscle signals, and software systems.
Conclusion:
Studies have shown that there are many different orthoses in terms of power transmission systems, drive systems, and control systems, and each of these devices has different capabilities to assist patients. Although each of the introduced orthotic designs has advantages to meet the needs of their target community, they are not without limitations. Removing the limitations of these designs could play a role in enhancing the efficiency and better meeting the needs of those who use these devices.
