Figure 2From: Effect of step-synchronized vibration stimulation of soles on gait in Parkinson's disease: a pilot studyStride intervals of the left leg from a 45-year-old Parkinson's disease subject obtained during 6-minute walking without (left) and with (right) the vibratory stimulation of soles. Vibratory stimulation reduced the coefficient of variation of stride interval from baseline value 11.49% (SD = 62.0 ms) to 9.43% (SD = 44.2 ms).Back to article page
