An Experimental Study of the Comfort of Stroke Rehabilitation Gloves Based on ANSYS
Pages 303 - 314
Abstract
In recent years, stroke diseases show a trend of rapid population growth and younger age, and impaired hand function is one of the main manifestations of stroke, and the market demand for rehabilitation gloves has expanded. In order to study the comfort of stroke rehabilitation gloves, the influence of different shapes of finger sleeves of tendon rehabilitation gloves on patient comfort was analyzed by finite element simulation, and guidance was provided for the comfort design of rehabilitation gloves. Combined with the existing research and market products of rehabilitation gloves, the factors affecting the comfort of rehabilitation gloves were analyzed; Using the finite element simulation method, the contact pressure generated between the finger sleeve and the finger of the tendon glove was simulated by static analysis, and five different modeling schemes were established according to the existing finger sleeve form, and the influence of finger sleeve size, shape, wrapping degree and other factors on the comfort of finger pressure was analyzed. Through the analysis and comparison of the finite element simulation results between different finger sleeve schemes and fingers, it is finally concluded that (1) generally soft fabrics have better pressure comfort than exoskeletons finger sleeves, and no matter what form of finger sleeves, longer sizes can reduce the pressure on fingers; (2) Increasing the fit between the exoskeleton finger sleeve and the finger surface can effectively improve the pressure comfort of the finger sleeve, and the hollow feature is easy to cause excessive contact pressure on the finger; (3) The contact pressure between the finger sleeve and the finger is less when the fixed parts are fully covered. This paper uses the finite element simulation analysis method to analyze the pressure comfort of tendon gloves, verifies the application value of the finite element method in product comfort design, and provides effective support for the comfort design and development of tendon rehabilitation gloves.
