简要总结
This study wants to know if using handheld dynamometry (HHD) to test leg strength in persons who have had a stroke, will reduce mistakes and give therapists better information to use for therapy. This study will collect normal values of leg muscle peak force production, cumulative peak force production, and sustained peak force production in patients with chronic stroke.
详细描述
The Activbody Activ5 device will be used for data collection with all information logged and stored through the device's app and transferred to secure files. Assessment of isometric muscle strength and power will be performed as follows: * Hip flexors with the participant seated and hips and knees flexed at 90 degrees * Knee extensors with the participant seated and hips and knees flexed at 90 degrees * Knee flexors with the participant seated and hips and knees flexed at 90 degrees * Ankle plantarflexors with the participant lying supine with the ankle in plantargrade and hips and knees extended * Ankle dorsiflexors with the participant lying supine with the ankle relaxed and hips and knees extended * Hip abductors with the participant lying supine and hips and knees extended * Hip adductors with the participant lying supine and hips and knees extended * Hip extensors with the participant lying prone and hips and knees extended 1 session, two trials per side
