Abstract
It has been reported that application of glycerin poultice to the flexor digotorum profundus in the middle phalanx of the little finger improves motor disturbance of Parkinson disease. I investigated whether the application of glycerin poultice to the semitendinous and semimembranous above the popliteal fossa (GSSP) improved motor disturbance in Parkinson disease. Step length and diameter of the pupil in 20 patients with Parkinson disease and 20 control subjects was evaluated before and after application of GSSP. Motor disturbance in patients with Parkinson disease was evaluated before and after application of GSSP. The application of GSSP increased step length and constricted the pupil in all subjects, which means that application of GSSP caused the decreased tension of the semitendinous and semimembranous and lowered sympathetic nerve activity. With application of GSSP, motor disturbance in patients with Parkinson disease was improved, which is caused by reversing the mechanism of the muscle mechanosensitive reflex.
