I'm looking to get a better sense of whether gait speed is mostly used as a research tool, or if people are using it in medical practice, based on real experiences. My initial research seems to indicate that it's indeed a research tool, but it seems it is also used in cardiology/thoracic surgery to assess post-operative risk.
What have been your experiences with gait speed? How are you currently measuring it? (Any relevant references or links are also greatly appreciated!)
