Abstract
Objective
The
purpose of the study was to assess the effectiveness of the multi-modal
exercise program (MMEP) in patients after stroke, and to identify
muscles that are the best predictors of functional performance and
changes in functional status in a 3-week rehabilitation program.
Methods
Thirty-one
post-stroke patients (60.6 ± 12.7 years) participating in a 3-week MMEP
took part in the study. Measurements of extensor and flexor strength of
the knee (Fext, Fflex) were
done. Functional performance was measured using Timed Up & Go test
(TUG), 6-Minute Walk Test (6-MWT) and Tinetti Test.
Results
The
rehabilitation program improved all the results of functional tests, as
well as the values of strength in the patients. Both baseline and
post-rehabilitation functional status was associated with knee flexor
and extensor muscle strength of paretic but not of non-paretic limbs. At
baseline examination muscle strength difference between both Fflex kg−1 and Fext kg−1
had an influence on functional status. After rehabilitation the effect
of muscle strength difference on functional status was not evident for Fext kg−1 and, interestingly, even more prominent for Fflex kg−1.
Conclusions
MMEP
can effectively increase muscle strength and functional capacity in
post-stroke patients. Knee flexor muscle strength of the paretic limb
and the knee flexor difference between the limbs is the best predictor
of functional performance in stroke survivors.
