Background:
Debate exists regarding the definition of sarcopenia and when
to be sarcopenic. Lately, Menant et al. (Osteoporosis Int 2016) showed that
isometric knee- extension muscle strength cut-points with values of the low-
est sex-specific quintile; <23.64 kg for men and <15.24 kg for women could
predict sarcopenic conditions.
Purpose / Aim of Study:
To investigate if these cut-points gave similar as-
sociations in the outcome of older adults with a hip fracture (HF) after ceased
municipality-based rehabilitation.
Materials and Methods:
Eighty (62 women) older adults with a mean (SD)
age of 76.6(7.8) years (46 with a femoral neck - and 34 with a trochanteric
fracture) were evaluated four months after HF. Maximal isometric knee-exten-
sion strength in the non-fractured limb with cut-points by Menant et al. were
compared with the Timed Up & Go (TUG) test; the 10 m walk test (10mWT),
and the 6-minute walk test (6MWT).
Findings / Results:
The maximal knee-extension strength was on average
27.7(14.1) kg in men and 16.8(7.4) kg in women (p=0.005), and of whom
28% and 26% respectively (p=0.8), had signs of sarcopenia. The group with
signs of sarcopenia performed significantly (p<.03) worse in the TUG (mean
diff. 3.02 [95%CI: 1.67 to 4.37] seconds), walked slower in the 10mWT (0.23
[0.1 to 0.35] meter per second), and walked a shorter distance in the 6MWT
(66.64 [29.9 to 103.19] meters), compared to the non- sarcopenic group.
Conclusions:
Although confirming the findings by Menant et al. in older adults
with HF, our findings probably underestimate the presence of sarcopenia in the
HF population. Thus, the estimate of approximately 25% with signs of sarcope-
nia after ceased rehabilitation was established in a group of older adults with a
high pre-fracture functional level, which underlines the importance of muscle
strength exercises offered to all older adults with HF.
