Abstract

Relevance: Clinical experience advocates manual stimulation in order to increase the sensation of the body and adjust the body schema. Unilateral treatment may affect the midline sensation and weight distribution in a standing position, but little evidence is available to support this procedure.
Purpose: The aim of the present study was to evaluate whether one-sided manual stimulation of one leg would influence the midline perception and weight distribution in standing position.
Methods/analysis: Twenty-one healthy young people received unilateral manual stimulation of the lower extremities for five minutes at one side after the other. Before and after each treatment weight distribution between the legs was measured while the participant was standing on two force plates.
Results: Stimulation of the leg with least weight-bearing increased the load on this leg significantly. When analyzing the data with respect to stimulation of the non-dominant leg, the stimulation increased the weight-bearing on this leg and a similar but reverse effect was seen for a stimulation of the dominant leg.
Discussion and conclusions: Apparently, unilateral manual stimulation of the lower extremity amongst healthy young people has an effect on the weight distribution between the two legs in a standing position. Even though a general effect of massage has been observed, the more local and specific effects on postural control are not as evident. In the present study, however, a local effect on the postural alignment was seen as a response to unilateral massage. It may be suggested, that the manipulated midline sensation and weight distribution reflects a state in which the participant's attention to a greater extent has been directed towards a specific body part due to the manual sensory stimulation.
Impact and implications: These findings advocate for the use of external afferent stimuli to enhance body perception and to influence the body schema.
