Leg power secrets revealed: how stroke and muscle loss affect your stride

This study measures how much force the leg joints (hip, knee, ankle) can produce and how muscles use oxygen in people with stroke or sarcopenia (age-related muscle loss). Researchers compare these measurements to healthy adults to understand what kind of help patients need when walking. The goal is to use this data to design better leg exoskeletons. 42 adults (18+ for stroke, 65+ for sarcopenia, and healthy volunteers) participate in strength tests and muscle oxygen monitoring.
