Objectives. To investigate (1) the association of seat height and (2) the association of arm position on the five times sit-to-stand test (FTSTS) times of individuals with stroke.Design. A cross-sectional study.Setting. University-based rehabilitation centre.Subjects. Patients (n=43) with chronic stroke.Methods. The times in completing the FTSTS with different seat height (85%, 100%, and 115% knee height) and arm positions (arms across chest, hands on thighs).Results. FTSTS times were significantly different between 85% and 100% seat heights, and between the 85% and 115% seat heights in both arm positions. However, there was no significant difference between the FTSTS times with the two arm positions at any seat height tested.Conclusion. Seat heights lower than the knee height result in longer FTSTS times, whereas arms positions did not significantly affect the FTSTS times.

A novel approach to quantifying postural stability in single leg stance is assessment of time-to-boundary (TTB) of center of pressure (COP) excursions. TTB measures estimate the time required for the COP to reach the boundary of the base of support if it were to continue on its instantaneous trajectory and velocity, thus quantifying the spatiotemporal characteristics of postural control. Our purposes were to examine: (a) the intrasession reliability of TTB and traditional COP-based measures of postural control, and (b) the correlations between these measures. Twenty-four young women completed three 10-second trials of single-limb quiet standing on each limb. Traditional measures included mean velocity, standard deviation, and range of mediolateral (ML) and anterior-posterior (AP) COP excursions. TTB variables were the absolute minimum, mean of minimum samples, and standard deviation of minimum samples in the ML and AP directions. The intrasession reliability of TTB measures was comparable to traditional COP based measures. Correlations between TTB and traditional COP based measures were weaker than those within each category of measures, indicating that TTB measures capture different aspects of postural control than traditional measures. TTB measures provide a unique method of assessing spatiotemporal characteristics of postural control during single limb stance.

Purpose The purpose of this study was to investigate the possible effects of smartphone usage in the biomechanical balance system. Method Twenty-five healthy young adults (10 men, 15 women) between the ages of 18 and 25 years without balance problems were included in the study. Sensory organization, adaptation, rhythmic weight shift, and functional limitation tests (unilateral stance, sit to stand, walk across, tandem walk, step quick turn, step up down, forward lunge) have been applied. Results Significant results were obtained in parameters of sensory organization, tandem walk, walk across, and unilateral stance tests ( p < .05). Conclusion The effects of using smartphones on postural control and balance in different circumstances, such as standing and walking, must be comprehensively determined to prevent accident.
