“…Considering the previous similarity between the young and old group for hesitation and co-ordination this difference was both surprising and intriguing. Smooth movement is not, necessarily, a characteristic of functional movement but it suggests a level of motor control has been attained, particularly when exhibited during a whole body movement that is inherently unstable, and requires distinct phases of acceleration, as in the case of STW [18]. The difference in smoothness uncovered between the young and old may represent fine scale changes in motor control, caused by age related changes in the neuromusculoskeletal system.…”

Restoring movement fluency is a key focus for physical rehabilitation; it's measurement, however, lacks objectivity. The purpose of this study was to find whether measurable movement fluency variables differed between groups of adults with different movement abilities whilst performing the sit-to-walk (STW) movement. The movement fluency variables were: (1) hesitation during movement (reduction in forward velocity of the centre of mass; CoM), (2) coordination (percentage of temporal overlap of joint rotations) and (3) smoothness (number of inflections in the CoM jerk signal)

“…The merging of two separate movements during the STW movement (sit-to-stand and gait initiation [18]) has been recognised as a suitable testing ground for movement fluency [1,3,8,11,15]. Sit-to-walk is a functional, whole body movement.…”

Abstract.[Purpose] The purpose of this study was to clarify the difference in sit-to-walk (STW) motion between young adults (YG) and an elderly persons (EG). [Subjects and Methods] Twenty-seven subjects (9 in YG and 18 in EG) were instructed to perform STW and to walk 3 m at a comfortable speed and at maximal speed. Data were obtained using a 3D motion capture system for kinematic data, and two force plates for kinetic data.[Results] The time required for STW was similar for both groups at both comfortable and maximal speeds, but the forward velocity of the center of gravity of the whole body (COG-WB) was higher for YG, and upward COG-WB at the time of the first heel contact was faster for YG. Ground reaction force analyses showed many differences between the groups. For YG, COG-WB moved forward and the first swing side was longer than for EG.[Conclusion] Forward and lateral COG-WB movements before the toe-off generate a progressive force. We suggest that YG subjects may have sufficient muscle power in their lower extremity to bear the progressive force, or that EG subjects may have learned anticipatory postural control which has shorter forward movement due to aging and declining physical function.

“…For this reason, the TUG movement is regarded as a functional activity more important than the STS movement. [7][8][9] The start of the STS movement and ambulation is related to the J KPT portant factors. 11 Moreover, when stroke patients do the STS movement, kinematic energy reduces and the weight distribution becomes asymmetric.…”

Purpose: This study was performed to examine the effect of action observation training on sit to-walk times in chronic stroke patients. Methods: Twelve stroke patients were randomly allocated to two groups, as follows: an action observation training (AOT) group and a scenery picture observation (SPO) group. The AOT group was engaged in video observation for 2 minutes 30 seconds with 12 ADL functional activities related to the sit-to-walk task: physical training was carried out in two repetitions lasting 2 minutes 30 seconds. The landscape imagery control group observed landscape picture for 2 minutes 30 seconds and then carried out the same physical training. The intervention involved a total of 12 sessions over 4 weeks, and each session lasted 30 minutes. The pre and post-tests measured the timed up and go test (TUG), Sit to stand test (STS), and Dynamic gait index (DGI). The Wilcoxon signed ranks test was used to compare pre-test and post-test result, and the Mann-Whitney U test was employed for comparison between groups. Results: The TUG time was significantly different between the AOT group and the SPO group. According to the findings, the experimental group's TUG was significantly decreased (p< 0.05). In comparison of the two groups, there was no significant in STS or DGI between the AOT group and SPO group. Conclusion: This study showed that the intervention can be used to decrease TUG time. Our research suggests that action observation training has a positive effect on sit-to-walk times in patients with chronic stroke.
