Clinimetrics of the Freezing of Gait Questionnaire for Parkinson Disease During the “off” State
Introduction: Freezing of gait, a common PD motor symptom, could increase the risk of falling. This study aimed to investigate the clinimetric attributes of the Freezing of Gait Questionnaire (FOGQ) for people with Parkinson disease in the “off” state. Methods: A total of 115 patients with Parkinson disease (PD; mean age, 60.25 years) were included. Acceptability, internal consistency (by the ...
متن کاملControl of a compass gait walker based on energy regulation using ankle push-off and foot placement
In this paper, we present a theoretical study on the control of a compass gait walker using energy regulation between steps. We use a return map to relate the mid-stance robot kinetic energy between steps with the two control inputs, namely, foot placement and ankle push-o↵. We show that by regulating the robot kinetic energy between steps using the two control inputs, we are able to: 1) genera...
متن کاملImpulsive ankle push-off powers leg swing in human walking.
Rapid unloading and a peak in power output of the ankle joint have been widely observed during push-off in human walking. Model-based studies hypothesize that this push-off causes redirection of the body center of mass just before touch-down of the leading leg. Other research suggests that work done by the ankle extensors provides kinetic energy for the initiation of swing. Also, muscle work is...
متن کاملA unified perspective on ankle push-off in human walking.
Muscle-tendon units about the ankle joint generate a burst of positive power during the step-to-step transition in human walking, termed ankle push-off, but there is no scientific consensus on its functional role. A central question embodied in the biomechanics literature is: does ankle push-off primarily contribute to leg swing, or to center of mass (COM) acceleration? This question has been d...
متن کاملPassive Ankle-Foot Prosthesis Prototype with Extended Push-Off
Current commercially available prosthetic feet have succeeded in decreasing the metabolic cost and increasing the speed of walking compared to walking with conventional, mostly solid prosthetic feet. However, there is still a large discrepancy when compared with a non‐disabled gait, and the walking pattern remains strongly disturbed. During the stance phase of the leg, t...
