Patterns of muscle strength loss with age in the general population and patients with a chronic inflammatory state

Abstract

Background: There is growing recognition of the serious consequences of sarcopenia on the functionality and autonomy in old age. Recently, the age-related changes in several inflammatory mediators have been implicated in the pathogenesis of sarcopenia. The purposes of this systematic review were two-fold: (1) to describe the patterns of muscle strength loss with age in the general population, and (2) to quantify the loss of muscle strength in rheumatoid arthritis as representative for an underlying inflammatory state. Handgrip strength was used as a proxy for overall muscle strength. Results: Results from 114 studies (involving 90,520 subjects) and 71 studies (involving 10,529 subjects) were..
