Sarcopenia is measured inconsistently, and today's Indian data quantify the consequence: nearly half of 44 studies used non-standard criteria, and the prevalence estimates ranged widely as a result. The same problem exists between clinics.
A patient labelled sarcopenic on grip strength alone in one service, and not sarcopenic in another that requires muscle mass measurement, has not changed. What changed is the definition, and that inconsistency makes it impossible to track someone over time or to act on a previous assessment.
So choose one consensus definition and apply it consistently — the Asian Working Group for Sarcopenia criteria are the appropriate regional choice, and their staged structure of probable, confirmed and severe is clinically useful because probable sarcopenia, identifiable from grip strength or chair-stand time alone, is enough to start resistance training and protein advice while confirmation is arranged. Record which criteria you used, so the next clinician can compare rather than start again.
- Choose one consensus definition — AWGS regionally — and stick to it
- Probable sarcopenia from grip strength or chair-stand alone is enough to act on
- Start resistance training and protein advice without waiting for confirmation
- Record which criteria were used, so assessments remain comparable over time
