The purpose of this study was to clarify the difference in muscle coactivation during postural control between older and young adults and to identify the characteristics of postural control strategies in older adults by investigating the relationship between muscle coactivation and postural control ability. Forty-six healthy older adults (82.0±7.5 years) and 34 healthy young adults (22.1±2.3 ye...

From ancient Greece to nowadays, research on posture control was guided and shaped by many concepts. Equilibrium control is often considered part of postural control. However, two different levels have become increasingly apparent in the postural control system, one level sets a distribution of tonic muscle activity ("posture") and the other is assigned to compensate for internal or external pe...

Instability, fear of falling and fall injuries are common problems for the older population and individuals with chronic disabilities. Development of screening tools and outcome measures of balance performance and fall risk has become of great interest for health professionals and researchers in the field of rehabilitation. Although linear modeling is desirable due to its simplicity, however, m...

Postural control may be an ideal physiological motor task for elucidating general questions about the organization, diversity, flexibility, and variability of biological motor behaviors using nonlinear dynamical analysis techniques. Rather than presenting "problems" to the nervous system, the redundancy of biological systems and variability in their behaviors may actually be exploited to allow ...

Aims: Amputation makes a person susceptible to postural deviation and compensatory movements and causes reduced performance, biocompatibility, pain, and dissatisfaction. The purpose of this study was to investigate the effect of eight weeks of a comprehensive rehabilitation protocol on indicators of postural control, back pain, quality of life, and gait speed in adults with unilateral lower lim...

BACKGROUND Postural control allows performance of daily and sports activities. The previous studies show that postural sway inceases in orthopaedic injuries such as osteoarthritis and total knee arthroplasty. OBJECTIVE To compare postural sway, risk of falling and function between individuals with and without patellofemoral pain syndrome (PFS). METHODS This study included 22 subjects with p...

BACKGROUND Postural control and falls in the elderly constitute a major health problem. The interest in balance deficits is growing, as concern about the rising costs of health care increases. This issue is particularly relevant to the elderly population in which falls occur most frequently. Postural control in the elderly was studied using a cognitive approach. OBJECTIVE The purpose of this ...
