In this study, the authors used somatic sensations to Parkinson’s disease patients and discussed the immediate effect of external stimuli, along with the usefulness of effects from continued intervention. The subjects were 10 patients. Measurement items used to examine the immediate effects included walking speed and number of steps in 10 meters, number of steps per minute, impression of walking with both of those who received vibratory stimulation and for ordinary ambulation. Also, as an examination of the continued effects, we investigated their one-week activity levels, PDQ-39, and impressions being dependent on the presence or absence of the vibratory stimulation intervention. Results showed a significant improvement in the number of steps per minute for stimulation. As for the continued effects, both the PDQ-39 and the activity levels showed a tendency for improvement. This study showed the utility of external stimulation using vibration for patients with Parkinson's disease.
