IC consists of using a cuff to measure blood pressure and calibrate 200 mmHg on the upper or lower limb.

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.", 'detailedDescription': "Parkinson's disease (PD) is a neurodegenerative disorder that causes a variety of motor and non-motor symptoms. Typically, patients with PD suffer from disabilities and secondary complications even when the disease is optimally treated, and many patients still have sedentary lifestyles, which in turn result in higher rates of mortality and comorbidity. Physical activity is an essential element in maintaining daily functional capabilities and quality of life. However, patients with PD have motor and non-motor deficits that can prevent or limit physical exercise, such as running or resistance exercise. 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, calibrated between 180 and 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. Recently, IC has been shown to improve cognitive performance in neurological patients with stroke, subcortical ischemia, and vascular dementia. However, there are no studies that have evaluated the effect of IC on motor and cognitive performance in patients with PD. The objective of the present study is to evaluate the chronic effect of IC on the motor and cognitive performance of patients with PD.
