The Effects of Ischemic Conditioning in Individuals With Parkinson's Disease

Ischemic conditioning (IC) is a promising therapy that can mimic the physiological effects of physical exercise. IC consists of using a cuff to measure blood pressure and calibrate 200 mmHg on the upper or lower limb. Thus, at alternating intervals of 5 minutes, ischemia or reperfusion occurs, depending on whether the cuff is inflated or deflated. IC induces changes in spinal cord excitability for the last reflex reactions of recruited motoneurons with improved balance control in healthy young people and improved learning in the elderly. The objective of the present study is to evaluate the chronic effect of IC on the motor function and cognitive performance of patients with Parkinson's disease. Furthermore, the investigators will evaluate secondary outcomes such as mobility, quality of life, and immunological responses.
