Effect of light finger touch in balance control of individuals with multiple sclerosis

Abstract

Deficit in balance control is a common and often an initial disabling symptom of multiple sclerosis (MS). The purpose of this study was to investigate if a light finger touch contact with a stationary surface is effective in improving upright postural stability in MS. Eleven individuals with relapsing–remitting MS were standing on a force platform with eyes open and closed, feet shoulder width apart and together, and with a light touch contact of the right index finger with a stable surface and without any contact. Balance was evaluated using center of pressure measures. Individuals with MS demonstrated significant postural instability in the absence of visual inputs and with reduced base of support (p<0.05). The availability of a light finger touch contact with a stable surface was effective in reducing postural sway in both, the sagittal and frontal planes, in all experimental conditions (p<0.05). Light finger touch contact is effective in improving postural control in people with MS and can be considered as a useful balance rehabilitative strategy.
