What is the objective measure used to assess functional status?

• A. VO2 max
• B. Gait speed
• C. Activities of daily living score
• D. Handgrip strength

Answer: (D)

Functional status is best captured by a direct measure of muscle function, and handgrip strength provides that in a simple, objective way. Measured with a handheld dynamometer, it quantifies the maximal force the forearm can exert and reflects overall muscle function. This single, reproducible test correlates with important clinical outcomes and nutritional status, making it a reliable marker to track changes during nutrition support. Other measures have limitations for this purpose. VO2 max gauges aerobic capacity and requires specialized testing, which isn’t routinely used to assess daily functional ability in nutrition care. Gait speed assesses mobility but can be affected by pain, joint issues, or balance problems, not just muscle strength. An activities of daily living score captures function but is often subjective, relying on patient or caregiver reporting. Because handgrip strength provides an objective, quick, and broadly informative snapshot of functional status, it’s considered the best choice.
