OBJECTIVE: To test the hypothesis that hybrid functional electrical stimulation
(FES) row training would improve aerobic capacity but that it would remain
strongly linked to level of spinal cord lesion because of limited maximal
ventilation. DESIGN: Longitudinal before-after trial of 6 months of FES row
training. SETTING: Exercise for persons with disabilities program in a hospitaL.
PARTICIPANTS: Volunteers (N=14; age range, 21-63y) with complete spinal cord
injury (SCI) (T3-11) who are >2 years postinjury. INTERVENTION: Six months of FES
row training preceded by a variable period of FES strength training. MAIN OUTCOME
MEASURES: Peak aerobic capacity and peak exercise ventilation before and after 6
months of FES row training. RESULTS: FES row training significantly increased
peak aerobic capacity and peak minute ventilation (both P<.05). Prior to FES row
training, there was a close relation between level of SCI and peak aerobic
capacity (adjusted R(2)=.40, P=.009) that was markedly reduced after FES row
training (adjusted R(2)=.15, P=.10). In contrast, the relation between level of
injury and peak minute ventilation was comparable before and after FES row
training (adjusted R(2)=.38 vs .32, both P<.05). CONCLUSIONS: The increased
aerobic capacity reflects more than increased ventilation; FES row training
effectively circumvents the effect of SCI on peak aerobic capacity by engaging
more muscle mass for training, independent of the level of injury.
