Multiple diagnostic criteria have been proposed by various expert groups and continues to be an area of research and debate. Despite the lack of a widely accepted definition,<unk>  was assigned an ICD-10 code (M62.84) in 2016, recognizing it as a disease state.<unk>  can be diagnosed when a patient has muscle mass that is at least two standard deviations below the relevant population mean and has a slow walking speed. The European Working Group on<unk>  in Older People (EWGSOP) developed a broad clinical definition for<unk> , designated as the presence of low muscle mass and either low muscular strength or low physical performance. Other international groups have proposed criteria that include metrics on walking speed, distance walked in 6 minutes, or grip strength. Hand grip strength alone has also been advocated as a clinical marker of<unk>  that is simple and cost effective and has good predictive power, although it does not provide comprehensive information. There are screening tools for<unk>  that assess patient reported difficulty in doing daily activities such as walking, climbing stairs or standing from a chair and have been shown to predict<unk>  and poor functional outcomes.
