“…Therefore, they suggest that patients should be positioned with the affected foot behind the unaffected one for symmetrical knee moment during performance of STS. Similarly, Masaya et al20 ) reported that cushion thickness affected STS motion among the elderly. They elucidated that increased cushion thickness induced inclined trunk anteriority and required greater knee extensor strength during STS motion.…”

[Purpose] Sit-to-stand (STS) is one of the important functional tasks people perform throughout the day. This study investigated whether varying angles of knee flexion affect STS patterns in individuals with hemiparesis by using a foot plantar pressure measurement system. [Methods] Fifteen stroke patients with hemiparesis participated for this study. They performed sit-to-stand with three angles of knee flexion (70°, 90°, and 110°). We measured the trajectory of the center of pressure, peak plantar pressure, and symmetry index using a Mat-scan system (Tekscan, South Boston, MA, USA). [Results] As a result, we found that there were significant differences among the three angle conditions (trajectory of center of pressure, peak plantar pressure on the affected side, and symmetry index). However, there was no significant difference in peak pressure according to the knee flexion on the unaffected side. [Conclusion] In the current study, we found that stroke patients with hemiparesis had a compensated STS pattern according to knee flexion angles. This indicates that the peak value of plantar pressure increased and that the trajectory of the center of pressure widened as the angle of knee flexion increased. We also suggest that hemiparesis patients should be more concerned about proper knee angle for symmetrical STS pattern.

Purpose. the evaluation of the sit-to-stand (StS) movement has been widely studied; however, very different protocols are used, making it difficult to choose a methodology. So, the purposes of this study were: (1) to identify the StS movement assessment protocols for lumbar spine, pelvis, or hip on the basis of video image analysis; (2) to investigate the reference values for these regions range of motion (ROM) using a systematic review with meta-analysis. Methods. the searches were conducted in BIREME, Embase, PubMed, ScienceDirect, Scopus, and Web of Science databases; manual searches were also performed. two independent reviewers selected the studies, extracted the data, and assessed the methodological quality and risk of bias. the methodological quality was verified by the Downs and Black scale and the strength of evidence by the GRADE system. Seventeen studies were included, from which data on sample, evaluation protocols, and ROM angles were extracted. Results and conclusions. the studies showed high strength of evidence. Acquisition protocols diverged, but most of the studies utilized 3D video image analysis with optoelectronic systems, backless seat with adjustable height, and asking the subject to perform 3 trials of the movement in self-referred speed, keeping the arms crossed. the meta-analysis provided reference values for adults hip ROM (compared with the thigh) of 81.19-93.71°. For the elderly, the angles for lumbar spine and hip position at the start of the StS movement were 0.20-3.99° and 73.58-78.06°, respectively.Citation: Gelain GM, Schmit EFD, De Mesquita PV, candotti ct.

ABSTRACT. Objective: Sit-to-stand motion (STS) is a dynamic motion utilized in fundamental activities of daily living and requires extensive joint movement in the lower extremities and the trunk and coordination of multiple body segments. The present study aimed to investigate whether aging affects the motor coordination of joint movements required to stabilize the horizontal and vertical movement of center of mass using the uncontrolled manifold (UCM) analysis. Method: We recruited 39 older adults with no musculoskeletal and/or neuromuscular conditions that affected STS, along with 21 healthy younger adults. All subjects performed five STS trials from a chair with the seat height adjusted to the length of their lower leg at a selfselected motion speed. Kinematic data were collected using a three-dimensional motion analysis system. We performed the UCM analysis to assess the effects of joint angle variance (elemental variable) to stabilize the horizontal and vertical movement of COM (performance variable) and calculated the joint angle variance that does not affect COM (VUCM), the variance that affects COM (VORT), and the synergy index (ΔV). Results: ΔV values in the horizontal direction were higher in the older adults than in the younger adults, but ΔV values in the vertical direction were lower in the older adults than in the younger adults. Conclusion: Older adults require increasing levels of stabilization of horizontal movement of COM after buttocks-off in the STS maneuver. As a result, variance in the joint angle of the lower extremities indicated no kinematic synergy for stabilizing the vertical movement of COM. Key words: Uncontrolled manifold analysis, Sit-to-stand, Aging (Phys Ther Res 20: 44-50, 2017)T he Sit-to-stand motion (STS) is a highly common motion that is performed as frequently as gait in daily life. It requires two tasks: transitioning the center of mass (COM) from a wide base of support (BOS) provided by the buttocks, thighs, and feet to a narrow BOS provided by the feet alone, and lifting the COM from the height of sitting to that of standing. STS also represents a motion for which the muscle strength of lower extremities is particularly important 1,2 ) . STS is associated with applied motions such as transfer and walking, and its acquisition is an essential factor to improve mobility capability. STS results from interactions characteristic of task-related, individual, and environmental constraints 3) .
