Zapping legs to ease breathing struggles in COPD patients

This study is testing whether adding electrical stimulation to leg muscles during standard pulmonary rehab helps people with COPD feel less short of breath and fatigued during activity, and more confident about exercising. It will involve 40 participants who have mild to severe COPD and are already in a rehab program. One group will get the standard rehab plus the leg stimulation, while another gets only standard rehab, to compare results over eight weeks.
