Abstract
[Purpose] The aim of this study was to develop a new handle holder by modifying the inclination of the existing handle holder to reduce load on the wrist joints. [Subjects and Methods] The subjects of this study consisted of 25 elderly people aged 65 years or older accustomed to a walker-assisted gait. Two types of handle holders ((1) standard handle holder (2) inclination handle holder) were applied to all subjects and their wrist joint movement and muscle activity were measured while they conducted 10 cycle walker-assisted gait. [Results] The use of an inclination handle holder during the walker-assisted gait decreased considerably the extensor carpi radialis longus activity and angles of the ulnar deviation and wrist extension. [Conclusion] Improvements in the overall structure of a walker may be a new tool for improving existing walker users but the replacement cost will be expensive. The inclination handle holder presented in this study decreases the burden on the wrist joints of walker users without any overall structural changes in the walker, thereby reducing the occurrence of musculoskeletal diseases of the wrist joint during the walker-assisted gait of elderly people.
