Handgrip strength is used as an objective measure of functional status because it reflects which attribute?

• A. Overall muscle strength
• B. Cardiovascular endurance
• C. Cognitive function
• D. Flexibility

Answer: (A)

Handgrip strength is used as a quick, objective indicator of functional status because it reflects overall muscle strength. The grip strength you measure tends to mirror the strength of muscles throughout the body, and because muscle mass and function often decline together with aging (sarcopenia), a stronger grip generally signals better general strength and a greater ability to perform daily activities. It’s practical, reliable, and correlates with outcomes like independence and even risk of disability or adverse events.

The other attributes aren’t what grip strength directly measures. Cardiovascular endurance concerns heart and lung capacity for prolonged activity, which isn’t captured by a single grip measure. Cognitive function relates to mental processes, not muscle force. Flexibility concerns the range of motion around joints, which grip strength does not assess.
