Transitions sit to stand and stand to sit in persons post-stroke: Path of centre of mass, pelvic and limb loading – A pilot study

Experimental study on sit-to-stand (STS) movement: a systematic review

“…Physical illness affects the timing of STS and the STS strategy used by subjects. Among them, the most complicated situation is the population of severe hemiplegia, and the accurate STS movement law cannot be given at present (Vaughan-Graham et al 2019). Psychological factors have a significant impact on the movement performance of STS.…”

“…In moderate hemiplegia group, there were asymmetry in weight-bearing and knee joint strength distribution, while in severe hemiplegia group, there were differences in weight-bearing distribution between two sides, but there was almost symmetrical distribution of knee strength. The results of Vaughan- Graham et al (2019) showed that the pelvic load distribution and the deviation of COM were different in spite of similar hemiplegic manifestations. These showed that the movement problems of hemiplegic patients were very complex, and the current measurement technology has certain limitations.…”

“…1b shows the joint angle trajectories to distinguish each STS phase in an STS period. In 11 articles (Yamada and Demura 2009;Spyropoulos et al 2013;Petrella et al 2019;Lindemann et al 2003;Turcot and Lachance 2019;Vaughan-Graham et al 2019;Jeyasurya et al 2013;Satomi 2012;Yoshioka et al 2007;Damien and Smith 2006;Brunt et al 2002;Kamnik et al 1999), the force plate and related techniques were used to measure the force changes of STS, and the photoelectric motion capture system was used in ten articles (Spyropoulos et al 2013;Petrella et al 2019;Turcot and Lachance 2019;Vaughan-Graham et al 2019;Tully et al 2005;Burnfield et al 2012;Satomi 2012;Damien and Smith 2006;Kamnik et al 1999;Mourey et al , 1998). Other experimental instrumentation included accelerometer (Yamada et al 2013), dynamometer or force sensor (Anabèle et al 2013;Damien and Smith 2006;Médéric et al 2006), surface electromyography measurement system (Anabèle et al 2013;Burnfield et al 2012;Satomi 2012;Brunt et al 2002).…”

“…When the seat height was not taken as the research object of the STS experiment, the seat height was set to a certain value between 40 and 47 cm by some researchers (Spyropoulos et al 2013;Lindemann et al 2003;Vaughan-Graham et al 2019;Burnfield et al 2012;Satomi 2012;Yoshioka et al 2007;Damien and Smith 2006), and there was no back and armrest. Among these, Yoshioka et al (2007) set the chair height to 0.40 m, since the Japan Industrial Standard and British Standards Institute recommended 0.40 m as the standard chair height and the toilet pedestal height.…”

“…When the purpose of the study is to explore the characteristics of people with a particular disease in the STS process, it is necessary to select specific subjects (Petrella et al 2019;Vaughan-Graham et al 2019;Anabèle et al 2013;Brunt et al 2002;Kamnik et al 1999). Two articles (Anabèle et al 2013;Brunt et al 2002) selected healthy people and patients for control-experiment.…”
