Muscle Mechanography: A Novel Method to Measure Muscle Function in Older Adults

Muscle function decline is a commonly observed process that occurs with aging. Low muscle function, an essential component of sarcopenia, is associated with negative outcomes, including falls, fractures, and dependency. Although many tools have been developed and are used to assess muscle function in older adults, most have important limitations. Muscle mechanography is a novel method that can quantitatively assess muscle function by performing movements such as heel raises, chair rises, or jumps on a ground reaction force plate. It can also assess balance by measuring sway of the center of pressure. Muscle mechanography promises to have advantages over currently used tools, appears to have better reproducibility, and can assess a broader range of physical function-from master athletes to frail individuals. Older adults can safely perform muscle mechanography measurements. Further research is needed to determine whether muscle mechanography can predict outcomes such as falls, fractures, and mortality.
