  • The purpose of this study was to investigate impact of wearing low-level current wrist guards on pain scale, range of motion (ROM), and muscle strength in elderly women with Carpal Tunnel Syndrome (CTS). Subjects were 12 elderly women aged between 65 and 85 years who were diagnosed with CTS symptoms. Measurements included grip strength and wrist ROM. Wrist ROM was assessed through flexion and dorsiflexion. Wrist guards were worn. After two weeks, pain level was assessed using the Visual Analogue Scale (VAS). Results showed a significant reduction in VAS score in the MES group after stimulation, whereas there was no difference in the control group. However, there was no significant difference in ROM between the MES group and the control group. Grip strength increased in the MES group after two weeks (p ≤ 0.001). In conclusion, clinical trials suggest that MES wrist guards might be provided as an adjunctive treatment method for CTS patients. This study provides foundational data for the design and use of auxiliary devices such as gloves in the field of MES research for pain reduction, ROM improvement, and muscle strength enhancement resulting from CTS.

  • Forearm fractures in children are very common among all pediatric fractures. However, biomechanical investigations on the pediatric forearm are rather scarce, partially due to the complex anatomy, closely situated, interrelated structures, highly dynamic movement patterns, and lack of appropriate tools. The purpose of this study is to develop a computational tool for child forearm investigation and characterize the mechanical responses of a backward fall using the computational model. A three-dimensional 10-year-old child forearm finite element (FE) model, which includes the ulna, radius, carpal bones, metacarpals, phalanges, cartilages and ligaments, was developed. The high-quality hexahedral FE meshes were created using a multi-block approach to ensure computational accuracy. The material properties of the FE model were obtained by scaling reported adult experimental data. The design of computational experiments was performed to investigate material sensitivity and the effects of relevant parameters in backward fall. Numerical results provided a spectrum of child forearm responses with various effective masses and forearm angles. In addition, a conceptual L-shape wrist guard design was simulated and found to be able to reduce child distal radius fracture.
