Paper

Abstract

With an aging population, muscle health, encompassing locomotion and metabolic function, has become a public health priority. Handgrip strength is a validated surrogate measure of general muscle strength, but measurement may not be feasible in low-resource settings. The SARC-F questionnaire (Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls) provides a simple, low-cost, and practical tool for sarcopenia screening, though its optimal cut-off remains debated.

The following analysis is generated by AI and may contain errors. It is separate from the authors’ abstract and is not peer review.

Research summary

The paper evaluates the predictive validity of SARC-F cut-off scores for identifying low muscle strength in older adults. This research is relevant as it addresses muscle health, a critical aspect of aging and longevity, particularly in low-resource settings.
