Sarcopenia : What are the consequences ?


 

Sarcopenia is causing a general deterioration of the physical condition resulting in a loss of muscle mass and strength leading to an increased risk of falls1, decreased quality of life and loss of independence 2,3.As such, sarcopenia is now recognized as a central factor in the pathogenesis of frailty in the elderly.4

Diagnosis

The diagnosis of sarcopenia based on an assessment of:

• Muscle mass (quantified by anthropometric measurements, or by impedance absorptiometry (DEXA)
• Muscle strength (estimated by grip strength)
• The physical performance (walking speed, chair lift, get-up-and-go).
