Clinical Effects of Scalp Electrical Acupuncture in Stroke: A Sham-Controlled Randomized Clinical Trial
The Journal of Alternative and Complementary Medicine, 05/09/2012Hsing WT et al.
The results support further testing of scalp electrical acupuncture for the treatment of stroke as well further mechanistic studies to understand mechanisms associated with the observed improvement.
Sixty-two (62) subjects who were at least 18 months postdiagnosis of ischemic stroke were randomized to receive 10 sessions of placebo or active low-frequency electrical stimulation (2/100Hz) using subcutaneous acupuncture needles over the scalp.
Functional and neurological evaluations were indexed by the Barthel, Rankin, and National Institutes of Health Stroke Scale (NIHSS).
Results show that there was a significant difference in functional improvement between the sham and active group as indexed by NIHSS scale.
The active group had a larger functional improvement after 10 sessions of scalp electrical acupuncture.
The other two functional scales (Rankin and Barthel) failed to show significant differences between the two treatment groups.
