Exercise and Brain Stimulation for Post-stroke Depression
Treating Depression and Enhancing Locomotor Recovery Post-stroke
This project will assess the effects of aerobic exercise training (AET), repetitive transcranial magnetic stimulation (rTMS) or their combination on depressive severity as well as locomotor function in persons with post-stroke depression (PSD). Both AET and rTMS are established stand-alone treatments for non-stroke related depression, though neither has been adequately studied post-stroke. Furthermore, substantive research indicates that AET improves post-stroke locomotor function, thus offering a novel approach for treating PSD as well as an established vehicle to study the effects of PSD on response to rehabilitation.
The purpose of this project is to determine the impact of AET, rTMS and their combination (AET+rTMS) treatments on post-stroke depressive symptoms and locomotor function so as to guide the development of a future clinical trial. A total of 40 depressed post-stroke subjects will be randomly assigned to one of four groups 1) AET; 2) rTMS; 3) combined AET and rTMS (AET+rTMS) or 4) control (sham rTMS) group (n=10 per condition; equally distributed with mild and moderate MDD). Further, an additional 10 non-depressed post-stroke subjects will complete 8 weeks of AET so as to allow us to determine the effects of PSD on response to training (Aim 2). Training (AET, rTMS and AET+rTMS) will take place over an 8-week period, three times per week on non-consecutive days. Measures of depression (HRSD17) as well as self-selected walking speed (SSWS) will be performed prior to the initial treatment session of each week as well as 8 weeks following cessation of treatment. Additional measures of locomotor function (walking endurance and amount of daily community stepping) will be assessed prior to training (pre), following 4 weeks of training (mid), upon completion of 8 weeks of training (post) as well as 8 weeks following cessation of training (follow-up), allowing determination of the efficacy (and persistence) of training on these outcomes.
