Background and purpose: Previous studies have investigated the correlation between activity of superficial trunk muscle and postural control in patients with low back pain (LBP), but the relationship between deep trunk muscle activity, as spinal stabilizer, and postural control during standing postural tasks is not clear yet. This study investigated the relationship between abdominal musc...
PURPOSE To relate balance measures to visual field (VF) damage from glaucoma. METHODS The OPAL kinematic system measured balance, as root mean square (RMS) sway, on 236 patients with suspect/diagnosed glaucoma. Balance was measured with feet shoulder width apart while standing on a firm/foam surface with eyes opened/closed (Instrumental Clinical Test of Sensory Integration and Balance [ICTSIB...
The foot represents a small base of support as an important biomechanical parameter that the body maintains balance. It is assumed that postural stability performance could be affected by even minor alteration in the support surface in upright standing position. Therefore, the purpose of this study was to determine if individuals with different foot types would demonstrate differences in static...
[Purpose] The purpose of this study was to investigate the effect of local vibration stimuli on body balance (trace area, trace length, and velocity) in healthy adults during double-leg standing. [Subjects and Methods] Thirty-nine subjects (10 male, 29 female) participated in this study. They were asked to keep their balance while holding four positions: standing with their eyes open, with and ...
PURPOSE Sample entropy (SampEn) is an analysis to evaluate movement complexity of the center of pressure (COP). A lower value of SampEn indicates lower complexity of COP variability, that is, rigidity, and lower degrees of freedom. Previous studies reported the association of increased SampEn with improved standing balance ability in young subjects. However, no studies have examined these relat...
Closed-loop controlled functional electrical stimulation (FES) applied to the lower limb muscles can be used as a neuroprosthesis for standing balance in neurologically impaired individuals. The objective of this study was to propose a methodology for designing a proportional-integral-derivative (PID) controller for FES applied to the ankle muscles toward maintaining standing balance for severa...
