Five-repetition sit-to-Stand test among patients post-stroke and healthy-matched controls: the use of different chair types and number of trials

A Comparison of Sit to Stand Movement between Stroke Subjects and Healthy Subjects

“…If the right hemisphere of the brain is involved in the injury, the STS movement will also be affected since the injury of nerve function is manifested in the form of injury of motor function [24] . Extensors muscles' weakness in the affected limb may also interfere with the weight bearing distribution vertically [25] .…”

“…Cheng, Liaw, Wong, Tang, Lee and Lin [27] found subjects who fell before needing extra time to stabilize swing around the center of mass and took the longest time (4.32 s) to finish STS than healthy people (1.88 s) and stroke patients who never experienced falls (2.73 s), and this finding revealed the increased time during STS could be a significant indicator of the likelihood of falling due to altered activation patterns of important lower limb muscles on the affected side. For healthy people to make full use of the kinetic energy acquired during forwarding movement, the standing movement of seat-off to the end must follow the horizontal movement of beginning to seat-off at the fastest speed, however, stroke patients fail to perform this action coherently [6] , since increasing the speed and the stability of STS performance are connected with the increased muscular needs of the trunk for the generation and control of the flexor momentum, and these are the abilities most stroke patients lack, which creates the different [25] .…”
