UPPER EXTREMITY KINETICS DURING LOFSTRAND CRUTCH-ASSISTED GAIT IN CHILDREN Neha Bhagchandani, B.E. Marquette University, 2010 Complete biomechanical analysis helps evaluate the motion during various gait patterns for the upper and lower extremities. Extensive studies have been performed to evaluate unassisted gait patterns, but very little has been accomplished for studying assisted motion. Chi...

We investigated swing-through axillary crutch gait (nonweight bearing on the left lower extremity) to determine the effects of gait speed, crutch length, and handle position on the forces exerted at the hands and on the moments exerted about the elbow joints. Ten healthy subjects, skilled in swing-through crutch gait, walked at three speeds using fitted crutches, at a fixed speed with four diff...

The blind used traditional crutch to walk on the track in past. With increase of and complexity situation road, simple cannot give enough security blind. needs improvement active obstacle avoidance night safety meet demand. In this paper, a smart is designed. ultrasonic ranging sensor, laser color photosensitive resistance, buzzer vibrator are linked together with Arduino microcontrollers reali...

In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...

BACKGROUND Individuals with spinal cord injury (SCI) often use a wheelchair for mobility due to paralysis. Powered exoskeletal-assisted walking (EAW) provides a modality for walking overground with crutches. Little is known about the EAW velocities and level of assistance (LOA) needed for these devices. OBJECTIVE The primary aim was to evaluate EAW velocity, number of sessions, and LOA and th...

OBJECTIVE Mobility limitations relate to dependency in older adults. Identification of older patients with mobility limitations after hospital discharge may help stratify treatment and could potentially counteract dependency seen in older adults after hospitalization. We investigated the ability of four physical performance measures administered at hospital admission to identify older medical p...
