introduction: the purpose of this study was to compare the effect of a whole body vibration training (wbvt) protocol with a conventional physiotherapy (pt) program on knee joint position sense and balance after anterior cruciate ligament (acl) reconstruction. methods: the study was designed as a single blind rct, twenty athletes with unilateral acl reconstruction were randomly assigned to the w...

BACKGROUND Recently, several studies have reported age-associated increases in muscle coactivation during postural control. A rigid posture induced by strong muscle coactivation reduces the degree of freedom to be organized by the postural control system. The purpose of this study was to clarify the effect of balance training on muscle coactivation during postural control in older adults. MET...

For consciously performed motor tasks executed in a defined and constant way, both motor imagery (MI) and action observation (AO) have been shown to promote motor learning. It is not known whether these forms of non-physical training also improve motor actions when these actions have to be variably applied in an unstable and unpredictable environment. The present study therefore investigated th...

OBJECTIVE To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. METHODS We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Master¯ force platform system with the foll...

Introduction: Sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. The aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. Materials and methods: ...

Multiple sclerosis (MS) is a chronic disease of the nervous system. This potentially debilitating disorder often results in a general degradation of motor function. In particular, MS patients have been shown to exhibit altered balance dynamics while standing [1]. This altered balance is characterized by a large amount of postural sway [1]. Increased postural sway has also been observed in the m...

INTRODUCTION Postural control is essential for any movement task, but postural control strategies during one task in a specific environment may not generalize to another task or situation [1]. Thus, it is difficult to identify common postural control mechanisms across tasks. Control of balance during walking and during quiet standing likely involve both overlapping and independent control syste...

A deviation from the dorsal-side-up body posture in quadrupeds activates the mechanisms for postural corrections. Operation of these mechanisms was studied in the rabbit maintaining balance on a platform periodically tilted in the frontal plane. First, we characterized the kinematics and electromyographic (EMG) patterns of postural responses to tilts. It was found that a reaction to tilt includ...

Dynamic posturography has become an important tool for understanding standing balance in clinical settings. A key test in the NeuroCom dynamic posturography system, the Sensory Organization Test (SOT) provides information about the integration of multiple components of balance. The SOT test leads to an outcome measure called the equilibrium score (ES), which reflects the overall coordination of...

Balance training and postural response assessment have been for decades two separate tasks in the rehabilitation medicine. The former concerns physiotherapy and the latter diagnostics. The virtual-reality technology does not only enhance the possibilities of balance training, but in combination with a haptic floor enables the subjects to gain a postural imbalance experience. The differences in ...
