Objective
Compare the effects of contralaterally controlled neuromuscular electrical stimulation (CCNMES) versus cyclic neuromuscular electrical stimulation (NMES) on lower extremity impairment, functional ambulation, and gait characteristics.
Design
Twenty-six stroke survivors with chronic (≥6mo) footdrop during ambulation were randomly assigned to six weeks of CCNMES or cyclic NMES. Both groups had ten sessions per week of self-administered home application of either CCNMES or cyclic NMES plus two sessions per week of gait training with a physical therapist. Primary outcomes included lower extremity Fugl-Meyer score, modified Emory Functional Ambulation Profile, and gait velocity. Assessments were made at pretreatment, posttreatment, and at 1 and 3 months posttreatment.
Results
There were no significant differences between groups in the outcome trajectories for any of the measures. With data from both groups pooled, there were significant but modest and sustained improvements in the Fugl-Meyer score and the modified Emory Functional Ambulation Profile, but not in gait velocity.
Conclusions
The results support the hypothesis that gait training combined with either CCNMES or cyclic NMES reduces lower extremity impairment and functional ambulation, but do not support the hypothesis that CCNMES is more effective than cyclic NMES in chronic patients.
The results support the use of the SULCS to measure upper limb capacity in patients who are less than 2 years poststroke with moderate to severe hemiplegia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
