An observational study has found that functional impairments like stooping, crouching, or kneeling (SCK) in older adults are predicted by decreased muscle strength.
Researchers discovered that adults with SCK difficulty had significant decreases in adjusted strength measurements of trunk extensor, knee extensor, and ankle flexion muscles.
Physical therapist researcher and APTA member Allon Goldberg, assistant professor in the Department of Health Care Sciences at Wayne State University in Detroit, Michigan, said: "As with standing up from a chair, stooping, crouching, and kneeling movements require coordination of the whole-body center of mass over a wide range of postures in order to prevent a loss of balance or fall.
"More research is needed, but it is reasonable to predict that a physical therapy program to improve strength in older adults who have difficulty performing basic stooping, crouching, or kneeling movements could lead to improvements in performing these activities, and these improvements could be associated with reduced number of falls."
The aim of the study was to compare trunk and lower-extremity muscle strength differences in older adults who had difficulty with stooping, crouching, or kneeling with older adults who did not have these difficulties.
