Objective: To compare the effects of transcranial direct current stimulation (TDCS) with traditional Chinese acupuncture on upper-extremity (UE) function among patients with stroke.
Materials and Methods: Participants with subacute to chronic stroke who had moderate to severe UE functional impairment were randomly allocated to the TDCS or electro-acupuncture group, then underwent three weeks of physical therapy and occupational therapy, with 20 minutes of a-TDCS (2 mA) or electro-acupuncture applied during training once weekly. Primary outcome was determined using the Fugl-Meyer Assessment of motor recovery at 1-month follow-up.
Results: The 18 participants were allocated into two groups. Fugl-Meyer Assessment increased in both the TDCS and electro- acupuncture groups (5.00±3.08, p=0.001 and 7.4±4.9, p=0.002, respectively). However, no difference was found between groups, and no significant difference was observed in grip strength and task specific performance in both groups.
Conclusion: The application of TDCS might provide benefits in recovering hand motor function among patients with subacute to chronic stroke but does not go beyond those of electro-acupuncture.
