"resistance training with instability modified brain regions associated with the physiological alterations typical of gait freezing, boosted neuron activation, and enhanced brain plasticity in the affected regions.
“In addition to positive reports from the patients who took the training, clinical trials also evidenced significant improvements, especially a 60% reduction in gait freezing and a 70% reduction in motor symptoms of the disease. Another important outcome concerned the restoration of brain regions directly linked to the problem. "
