Frailty

Disease7 papers17 findings

Human studies associate frailty with lower handgrip strength in males, depression in females and GDF-15. A human trial reports reduced frailty with aerobic exercise during daycare rehabilitation; reviews link frailty to functional decline and describe reduced frailty with renal rehabilitation during maintenance haemodialysis.
