Combining rTMS & Aerobic Exercise to Treat Depression and Improve Post-Stroke Walking

Subjects will undergo rTMS to the left dorsolateral prefrontal region as a treatment for depression. Treatment will be performed three times per week for 12 weeks (36 sessions) . We will use a standard resting motor threshold (rMT) determination from unaffected abductor pollicis brevis. Treatments will be delivered at the EEG coordinate for F3 (approximating the left DLPFC) and will be found using the Beam-F3 method. A total of 5000 pulses/session will be delivered at 10Hz with an intensity of 120% of rMT.

The goal of AEx will be 20 minutes of continuous walking at an intensity of \~70% of heart rate reserve (HRR calculated via the Karvonen method). The desired intensity will be achieved by a combination of increasing treadmill speed and incline. Rest breaks will be allowed as needed during training with the goal of progressing to 20 minutes of continuous walking.
