Saturated muscle activation contributes to compensatory reaching strategies after stroke.
The control and execution of movement could potentially be altered by the presence of stroke-induced weakness if muscles are incapable of generating sufficient power. The purpose of this study was to identify compensatory strategies during a forward (sagittal) reaching task for 20 persons with chronic stroke and 10 healthy age-matched controls. We hypothesized that the paretic anterior deltoid ...

متن کاملCompensatory strategies during normal walking in response to muscle weakness and increased hip joint stiffness.
Compared to young adults, older adults exhibit a slower walking speed, smaller step length, shorter swing phase time and decreased range of motion in their lower extremity joints. The underlying mechanisms causing these gait adaptations is not well understood, with various musculoskeletal parameters being put forth as contributing factors, including increased joint stiffness and decreased isome...
متن کاملStep Length Asymmetry Is Indicative of Compensatory Mechanisms Used to Overcome Plantarflexor Weakness in Post-stroke Hemiparetic Gait
Post-stroke hemiparetic subjects walk with asymmetrical step lengths that are highly variable between subjects and may be indicative of underlying compensatory mechanisms utilized to overcome paretic plantarflexor impairment. The goal of this study was to examine the walking biomechanics of post-stroke hemiparetic subjects grouped by step length asymmetry and compare them to healthy controls wa...
