OBJECTIVE: To compare the effects of classic progressive resistance training
(PRT) versus eccentric strength-enhanced training (EST) on the performance of
functional tests and different strength manifestations in the lower limb of
people with multiple sclerosis (PwMS). DESIGN: Experimental trial. SETTING:
Strength training program. PARTICIPANTS: PwMS (N=52; 19 men, 33 women) belonging
to MS associations from the Castilla y Leon, Spain. INTERVENTIONS: Participants
were assigned to 1 of 2 groups: a control group that performed PRT or an
experimental group that performed EST. In both groups, the knee extensor muscles
were trained for 12 weeks. MAIN OUTCOME MEASURES: Before and after 12 weeks of
training, maximal voluntary isometric contraction and 1 repetition maximum (1RM)
of the knee extensors were evaluated, as were the Chair Stand Test (CST) and
Timed 8-Foot Up and Go (TUG) functional tests. RESULTS: No differences were found
between the groups in the initial values for different tests. Intragroup
comparisons found significant differences in CST (F=69.4; P<.001), TUG (F=40.0;
P<.001), and 1RM (F=57.8; P<.001). For intergroup comparisons, EST presented
better results than PRT in the CST (EST, 4.7%+/-2.8%; PRT, 1.9%+/-2.8%; F=13.1;
P=.001) and TUG (EST, -2.9+/-4.7; PRT, -.41+/-5.6; F=5.6; P=.022). CONCLUSIONS:
In PwMS, EST leads to improvements in 1RM, TUG, and CST that are similar to those
of PRT. However, for patients who participated in this study, the EST seems to
promote a better transfer of strength adaptations to the functional tests, which
are closer to daily-living activities.
