[Purpose] The purpose of this study was to investigate the influence of fingertip light touch on the postural control in poststroke patients. [Subjects] In the study, the subjects were recruited through a rehabilitation hospital, and 21 patients were screened from among 30 volunteers. [Methods] The subjects participated in an experiment that measured postural sway during the static standing pos...

CONTEXT The multifidus muscle plays a role in controlling lumbosacral position and postural sway. One of its attachment sites is the exact site of spina bifida occulta (SBO). OBJECTIVE To investigate the role of the muscle for postural control in SBO. DESIGN Cross-sectional cohort. PARTICIPANTS Eighty subjects with SBO (38 in minor; 42 in major) and controls. INTERVENTIONS N/A. MAIN O...

OBJECTIVES This study aims to assess whether the plantar pressure, the foot posture index (FPI) and foot size can predict the postural sway velocity in terms of postural stability in unilateral stance. PATIENTS AND METHODS A total of 236 feet of 118 participants (62 males, 56 females; mean age 22.1±3.1 years; range 18 to 36 years) were enrolled. The feet were classified as prone, normal and s...

A process for anti-sway control of a rotating boom or other three-degree-of-freedom crane wherein the load is hoisted, at variable hoist lengths, by a cable suspended from a point that can be moved in space in three dimensions, either freely, or under known constraints. Initial acceleration of the load induces an initial sway to the load. A second lateral acceleration, equal to the first latera...

BACKGROUND Increased postural sway is well documented in patients suffering from non-specific low back pain, whereby a linear relationship between higher pain intensities and increasing postural sway has been described. No investigation has been conducted to evaluate whether this relationship is maintained if pain levels change in adults with non-specific low back pain. METHODS Thirty-eight p...

The time course of the center of pressure (CoP) during human quiet standing, corresponding to body sway, is a stochastic process, influenced by a variety of features of the underlying neuro-musculo-skeletal system, such as postural stability and flexibility. Due to complexity of the process, sway patterns have been characterized in an empirical way by a number of indices, such as sway size and ...

BACKGROUND To utilize the power of latent growth analysis to evaluate changes in postural sway during development in children who are either at high or low risk for developing alcoholism. METHODS A total of 629 assessments of postural sway have been performed in children and adolescents (n = 126) who were evaluated annually over a 7-year period. RESULTS Latent curve models indicated that th...

The purposes of this study were to examine whether body sway is altered immediately after strabismus surgery in children and to find preoperative clinical factors associated with body sway. In a prospective study, body sway was measured on 1-3 days before surgery and on the third day after surgery; for the measurements, computerized static stabilometry was carried out on 28 consecutive patients...

Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus...

Human quiet standing is accompanied by body sway. The amplitude of this body sway is known to be larger than would be predicted from simple noise effects, and sway characteristics are changed by neurological disorders. This large sway is thought to arise from nonlinear control with prolonged periods of no control (intermittent control), and a nonlinear control system of this kind has been predi...
