Pneumatic Ergonomic Crutches Chenzhang Xiao by Chenzhang Xiao instant download after payment.

Long-term crutch users utilize Lofstrand crutches for locomotion commonly using swing-through or reciprocal gait patterns. Repetitive high forces, hyperextension and ulnar deviation of the wrist, and excessive palmar pressure compressing the median nerve associated with crutch walking have reported to cause discomfort, joint pain, wrist strain, carpal tunnel syndrome and other serious injuries. To address these issues, we developed the pneumatic ergonomic crutches (PEC) that consisted of a pneumatic sleeve orthosis, an energy harvesting system and an energy storage system. The pneumatic sleeve orthosis utilized a soft pneumatic actuator, called fiber-reinforced elastomeric enclosure, coiled around the forearm and secured to the cuff. In the first study, sleeve orthosis performance was examined. Human subject testing indicated significantly improved wrist posture, increased loading sharing to the cuff, reduced and redirected palmar pressure while using the orthosis. In the second study, the fully-developed PEC was presented.
