A physical therapist is working with a patient who recently completed chemotherapy. Which test is MOST appropriate to measure changes in endurance over time?

• A. 10-Meter Walk for Time
• B. 6-Minute Walk
• C. Timed Up and Go
• D. Maximum VO2 Assessment

Answer: (B)

Endurance is best tracked with a test that reflects functional aerobic capacity during a sustained, submaximal activity and can be safely repeated to show real-world changes. The six-minute walk test fits this well: it measures how far a person can walk in six minutes, capturing everyday tolerance to activity and overall endurance. It’s practical to administer, well tolerated, and sensitive to small but meaningful changes over time, which is crucial for someone recovering after chemotherapy. In contrast, short gait-speed tests like a 10-meter walk or a Timed Up and Go focus on quickness and basic mobility rather than sustained effort, so they’re less informative about endurance. A maximal oxygen uptake test directly measures peak capacity but requires maximal exertion, specialized equipment, and more risk and fatigue—making it less suitable for frequent reassessment in someone recently treated with chemotherapy.
