OBJECTIVE: To investigate the contribution of muscle mass and handgrip strength
in predicting the functional outcome after hip fracture in women. DESIGN:
Observational study. SETTING: Rehabilitation hospital. PARTICIPANTS: White women
(N=123 of 149) who were consecutively admitted to a rehabilitation hospital
because of their first fracture of the hip. INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: We measured appendicular lean mass (aLM) by dual-energy x-ray
absorptiometry (DXA) 21.1 +/- 8.7 (mean +/- SD) days after hip fracture
occurrence in the 123 women. On the same day, we assessed grip strength at the
nondominant arm with a dynamometer. At the end of acute inpatient rehabilitation
we measured the ability to function in activities of daily living by using the
Barthel Index, and lower limb performance by using the Timed Up and Go (TUG)
test. RESULTS: We found significant correlations between handgrip strength
measured before rehabilitation and Barthel Index scores after rehabilitation
(rho=.50; P<.001), Barthel Index effectiveness (rho=.45; P<.001), and the TUG
test (rho=-.41; P<.001). Conversely, we found no significant correlations between
aLM/height(2) and Barthel Index scores after rehabilitation (rho=.075; P=.41),
Barthel Index effectiveness (rho=.06; P=.53), or the TUG test (rho=.005; P=.96).
Significant associations between grip strength and all the outcome measures
persisted after adjustment for 8 potential confounders, including Barthel Index
scores before rehabilitation, age, number of medications, number of
comorbidities, pressure ulcers, concomitant infections, time between fracture
occurrence and assessment, and aLM/height(2). CONCLUSIONS:
Grip strength, but not
DXA-assessed aLM, significantly predicted short-term functional outcome in women
after a hip fracture.
