“…At a comfortable speed, although no significant differences were shown in the vertical and forward velocities of COG-WB and COG-T between the two groups (Table 2), the results do show significant differences in all vertical and forwardbackward GRFs between them (Table 3). This inconsistency may have occurred because of quick and effective force generation of the leg, followed 15) . Tokumo et al 16) reported that people who had had a stroke initiated their gait with forward-backward GRF value lower than healthy older adults, although their motion was adjusted and performed at the same speed.…”

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.

“…PD patients showed high variability when they perform STS, which was also found by Ramsey et al [21]. Therefore, a precise conclusion could only be achieved through a more concise standardisation of all phases and increased sample.…”

“…Differences in STS movement between PA and CO have been analysed in the past [11][12][13]15,20,21]. These studies identified a variety of interactive variables for the performance of STS in healthy subjects, as well as in subjects with neurological disorders.…”

“…The sit-to-stand (STS) movement is operationally defined as a successful transfer of the body's center of mass (CM) from a sitting position where there is a large support base (thighs and feet) to a stable standing position 8,9 , followed by obtaining orthostatic balance when body oscillation must be controlled (stabilization phase) [10][11][12][13][14][15] . Therefore, it requires good coordination between the central nervous system (CNS) and the neuromuscular system 8,9 .…”

-Aims:Changes resulting from the gestational period may lead to changes in the biomechanics of women, which can alter the performance of functional activities such as sit-to-stand. Thus, the objective of this study was to investigate the influence of a virtual reality-based exercise protocol on the kinematic variables of the sit-to-stand movement in women in their second and third gestational trimesters. Methods: The sample consisted of 44 women selected according to the eligibility criteria, allocated into 4 groups: control group, 2 nd trimester (CG2T); experimental group, 2 nd trimester (EG2T); control group, 3 rd trimester (CG3T); and experimental group, 3 rd trimester (EG3T). All the volunteers answered the identification and evaluation form and were sent to the kinematic evaluation through the Qualisys Motion Capture System®. An intervention with game therapy was performed in 12 sessions of 30 minutes each, three times a week. Results: No statistically significant differences were found intra-(P> 0.54) and inter-groups (P> 0.059) for kinematic variables. However, there was a tendency for improvement in the analyzed variables after the proposed protocol. Conclusions: The data obtained suggest that the use of the Nintendo Wii Fit Plus® was not able to influence sit-to-stand kinematic variables in the analyzed women.
