Summary
This study tests whether a mild electrical pulse to the ear, combined with physical and speech therapy, can improve voice, swallowing, balance, and walking in people with Parkinson's disease. 46 participants will receive either active or sham stimulation during 12 sessions over 4 weeks, with follow-up at 8 weeks. The goal is to see if this non-invasive approach can ease common Parkinson's symptoms.
