Modifications and upper extremity orthotics for the Lofstrand crutch
… persons who use crutches in the US. During Lofstrand crutch mobility, irregular loads are placed upon the upper extremities during quadrupedal gait. During self-load bearing while walking with Lofstrand crutches, the arms can experience periodic loads every 1 s of up to 50% of body weight …

Pneumatic ergonomic crutches
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 …

Modeling and design of fiber reinforced pneumatic actuators for soft robotics applications
… The first one is a soft orthotic sleeve for Lofstrand crutch users. This sleeve helps in distributing the palm load to the forearm, thereby reducing the risk of wrist injury as well as improving the wrist posture. The second application is of a pipe climbing soft robot that uses bending and …

Design and analysis of fiber reinforced elastomeric enclosures with application in upper arm orthosis
Fiber Reinforced Elastomeric Enclosures (FREEs) are soft pneumatic actuators that deform in a predetermined fashion upon inflation. They are constructed using a hollow elastomeric cylinder reinforced by two families of helical fibers. This thesis analyzes the deformation behavior of FREEs by …
