Lower limb strength, but not sensorial integration, explains the age-associated postural control impairment

The effect of six weeks selected physical training on balance, postural control and lower limb function in children with Meningomyelocele

Meningomyelocele after cerebral palsy is the most common congenital defects of the nervous system that impairs the functioning of many body’s structures. This study aimed to assess the effect of six weeks selected physical training on balance, postural control and lower limb function in children with Meningomyelocele. In this quasi-experimental study, 10 boys aged 10-11 years with Meningomyeloc...

The influence of lower-limb dominance on postural balance.

CONTEXT AND OBJECTIVE Maintainance of postural balance requires detection of body movements, integration of sensory information in the central nervous system and an appropriate motor response. The purpose of this study was to evaluate whether lower-limb dominance has an influence on postural balance. DESIGN AND SETTING This was a cross-sectional study conducted at Faculdade de Medicina da Uni...

Influence of neuromuscular fatigue of the lower limb on postural control and associated central processes in young and older adults

The Effect of Lower Extremity Muscle Fatigue on Dynamic Postural Control Analyzed by Electromyography

Purpose: Postural control preserves organs and body parts in a proper biomechanical stance which exists in two forms: static and dynamic. Fatigue is one of the factors that affects postural control. This study aimed to compare the electromyography (EMG) activity of the lower extremity muscles before and after fatigue. Methods: This study was descriptive correlational and based on the research ...

Myocytic androgen receptor controls the strength but not the mass of limb muscles.

The anabolic effects of androgens on skeletal muscles are thought to be mediated predominantly through the androgen receptor (AR), a member of the ligand-dependent nuclear receptor superfamily. However, despite numerous studies performed in men and in rodents, these effects remain poorly understood. To characterize androgen signaling in skeletal muscles, we generated mice in which the AR is sel...
