Age-related sarcopenia contributes to functional decline, falls, fractures, morbidity and mortality of elderly people and was recognised as a disease entity (ICD-10-CM M62.84) in 2016. Whilst a consensus on the operational definition of the condition is awaited, most current definitions incorporate a combination of loss of muscle mass, strength and/or performance. Of those (10 or so) proposed to date, the vast majority of definitions use appendicular lean mass (ALM), derived from whole body dual-energy X-ray absorptiometry (DXA) scans, as the estimate of muscle mass.
