Optimal intensity and duration of walking rehabilitation in patients with chronic stroke: a randomized clinical trial. JAMA Neurol. 2023;80(4):342–51. doi:10.1001/jamaneurol.2023.0033

Stroke survivors may experience chronic deficits in walking speed and stamina because of compromised neuromotor function and endurance capacity. Moderate-intensity walking (40%–60% heart rate reserve [HRR]) is commonly used in rehabilitation, as it is superior to lower-intensity walking for improving walking capacity. The use of sustained vigorous-intensity (>60% HRR) walking is less likely to be achieved poststroke; however, the use of high-intensity interval training (HIIT) appears to afford stroke survivors the opportunity...
