The effect of a textured insole on anticipatory postural adjustments.
Purpose: To obtain preliminary data on the effect of a textured insole on postural control.
Methods: Nine healthy subjects were exposed to external perturbations applied to their shoulders while standing with or without a single textured insole. Body weight distribution and bilateral electromyographic activity (EMG) of trunk and leg muscles were recorded. Onsets of EMG activity of muscles were calculated and analyzed within the interval typical for anticipatory postural adjustments.
Results: When a textured insole was provided under one foot, subjects shifted their body weight towards the contralateral foot. With no insole, the anticipatory onsets of EMG activity of the left and right muscles were symmetrical; when a textured insole was used, the EMG onsets of the muscles on the contralateral side of the body were seen earlier as compared to the insole side. This early activation was more pronounced in the trunk muscles (p < 0.05).
Conclusions: Using a single textured insole under one-foot induced asymmetry of anticipatory onsets of EMG activity in healthy subjects. The outcome highlights the importance of investigating the role of a single textured insole in control of vertical posture and provides a foundation for future studies focussed on improvement of postural control in individuals with body asymmetry due to unilateral weakness.
期刊介绍：
Somatosensory & Motor Research publishes original, high-quality papers that encompass the entire range of investigations related to the neural bases for somatic sensation, somatic motor function, somatic motor integration, and modeling thereof. Comprising anatomical, physiological, biochemical, pharmacological, behavioural, and psychophysical studies, Somatosensory & Motor Research covers all facets of the peripheral and central processes underlying cutaneous sensation, and includes studies relating to afferent and efferent mechanisms of deep structures (e.g., viscera, muscle). Studies of motor systems at all levels of the neuraxis are covered, but reports restricted to non-neural aspects of muscle generally would belong in other journals.
