Overview of the concept of frailty and sarcopenia. Frailty is multifaceted and is measured predominantly across four domains, i.e., cognitive, psychological, social, and physical. The physical frailty domain is calculated across several variables like activity (assessed through physical activity scale), unintentional weight loss (>4.5 kg loss in 1 year), slowness (>7 s to travel 15 feet), exhaustion (self‐reported; at least 3 days a week), and weakness (reduced grip strength). Sarcopenia on the other hand is a measure of reduced grip strength along with reduced muscle mass, which is a part of one of the frailty domains.
