OBJECTIVE: To evaluate the influence of transcutaneous electrical nerve
stimulation in patients with stroke through a systematic review and
meta-analysis. METHODS: PubMed, Embase, Web of Science, EBSCO, and Cochrane
Library databases were searched systematically. Randomized controlled trials
assessing the effect of transcutaneous electrical nerve stimulation vs placebo
transcutaneous electrical nerve stimulation on stroke were included. Two
investigators independently searched articles, extracted data, and assessed the
quality of included studies.
The primary outcome was modified Ashworth scale
(MAS). Meta-analysis was performed using the random-effect model. RESULTS: Seven
randomized controlled trials were included in the meta-analysis. Compared with
placebo transcutaneous electrical nerve stimulation, transcutaneous electrical
nerve stimulation supplementation significantly reduced MAS (standard mean
difference (SMD) = -0.71; 95% confidence interval (95% CI) = -1.11 to -0.30; p =
0.0006), improved static balance with open eyes (SMD = -1.26; 95% CI = -1.83 to
-0.69; p<0.0001) and closed eyes (SMD = -1.74; 95% CI = -2.36 to -1.12; p <
0.00001), and increased walking speed (SMD = 0.44; 95% CI = 0.05 to 0.84; p =
0.03), but did not improve results on the Timed Up and Go Test (SMD = -0.60; 95%
CI=-1.22 to 0.03; p = 0.06). CONCLUSION: Transcutaneous electrical nerve
stimulation is associated with significantly reduced spasticity, increased static
balance and walking speed, but has no influence on dynamic balance.
