Point-Mass Biomechanical Model of the Upper Extremity During Lofstrand Crutch-Assisted Gait

Abstract: We propose a point-mass biomechanical model to estimate the forces and moments supported by the upper extremity during Lofstrand crutch-assisted gait. This model is based on the Newtonian classical mechanics and the angular momentum theorem. The system arm-crutch is divided into three segments: 1) crutch, 2) wrist-elbow, and 3) elbow-shoulder. The theoretical model was experimentally validated with a disabled person with spinal cord injury. Two crutch-assisted gait patterns have been chosen to carry out the ex… Show more

“…Most tennis players focus on improving the return technology, and their attention and investment in service technology are relatively low. ere is no doubt that high-quality service can increase tennis players' control of the game [13,14]. Based on the preparation posture, turn to the side holding the clapper, guide the racket close to the body, and swing the racket behind the body like a pendulum (it is not necessary to swing the straight arm back, but the palm must face the body).…”
