Power Exercise for Stroke Recovery (POWER)
POWER incorporates 3 progressive phases: Phase 1 Familiarization (Week 1) as a low-intensity version of the training program to acclimate participants to the movements (body weight resisted or light weights, RPE 2-3 "Fairly light" to "Moderate"). Phase 2 Strength (Weeks 2-5) progresses loads to achieve volitional fatigue within 6-8 repetitions (RPE 7-9 "Very hard" to "Very very hard"). Phase 3 Power (Weeks 6-10) will use intensities RPE 4-6 ("Somewhat hard" to "Very hard"), and exercises will be executed at the highest possible velocity to focus on muscle power. The Power phase is intentionally designed with exercises to emphasize functional movements such as fast sit to stands, lunging and calf raises.
- Other intervention
Strength Training Engaging Guidelines to Enhance Total Health (STRENGTH)
STRENGTH is based on current clinical practice guidelines for RET after stroke. It will include the same Familiarization week as the POWER program (Week 1), followed by progressive conventional RET involving 3 sets of 10-15 repetitions at moderate to high intensities (RPE 4-5 "Somewhat hard" to "Hard") (Weeks 2-10). The external resistance will be progressed to maintain this target RPE range. STRENGTH is matched with POWER in length (60-minute sessions over 10 weeks), frequency (3x/week) and format (in-person supervision).

About This Trial
Weakness is one of the most common consequences of stroke. For the over 750,000 Canadians living with stroke, many daily activities like standing from a chair, walking and balance not only require strength but often efforts in bursts, known as muscle power. Strength training can improve muscle strength and, when performed at higher speeds, can help build muscle power. Current guidelines for stroke recommend strength training but these are commonly performed at lower intensities and do not include any focus on building muscle power. There has been very little research on power training after stroke. A 10-week power training program for people living with stroke, Power Exercise for Stroke Recovery (POWER-Feasibility, NCT05816811) was recently evaluated. POWER includes 3 phases of progressive exercise: building familiarity with the upper and lower body exercises, then strength, and lastly muscle power. The results from POWER-Feasibility are promising, suggesting that POWER is safe and may improve stroke recovery. POWER-Feasibility was a small study (15 participants), and POWER was not compared to a control intervention. A pilot randomized controlled trial of POWER (POWER-Pilot) will now be conducted. Sixty people who are at least 6 months after stroke will be recruited. They will be randomly assigned to participate in POWER or standard strength training for stroke at lower intensities and without focus on power training. The feasibility of a randomized study will be examined, and whether POWER can improve walking, strength and balance compared to the control group. Results from POWER-Pilot will help design a larger randomized trial in the future (POWER-RCT), and may ultimately be important for stroke rehabilitation teams to better understand whether power training can help people recovering from stroke.
