Abstrakt:	Objectives: This study investigated the effects of transcranial direct current stimulation (tDCS) before and during the mirror visual feedback (MVF) on hand grip strength (HGS) and range of motion of the affected hand in children with spastic hemiplegia cerebral palsy (SHCP). Materials & Methods: Twelve children with SHCP participated in this randomized, crossover, and double-blind study. They were randomly exposed to one of four intervention conditions, including 1) a-tDCS-offline, 2) s-tDCS-offline, 3) a-tDCS-online, and 4) s-tDCS-online, with a one-week interval. Participants in the online condition received either anodal or sham tDCS during MVF, while those in the offline condition received tDCS before performing MVF. The tDCS was applied over the M1 area of the affected hemisphere for 20 minutes at 1 mA intensity. The HGS and range of motion of the wrist and elbow (ROM-W and ROM-E) of the affected limb were measured before (pre) and immediately after (post) interventions in each session. Results: The results showed that the HGS was significantly higher under a-tDCS-offline ( p=0.001 ), s-tDCS-offline ( p=0.004 ), and s-tDCS-online ( p=0.005 ) compared to the a-tDCS-online. Moreover, the ROM-W was significantly higher under a-tDCS-offline ( p=0.034 ), s-tDCS-offline (0.011), and s-tDCS-online ( p=0.027 ) compared to the a-tDCS-online. Eventually, the ROM-E was significantly higher under a-tDCS-offline, s-tDCS-offline, and s-tDCS-online compared to the a-tDCS-online ( p ˂0.001; p ˂0.001; p=0.01 , respectively). Conclusion: The results might have practical implications regarding the timing of the application of tDCS in conjunction with MVF in children with SHCP. Competing Interests: The author declares that they have no conflict of interest. (© 2024 The Authors. Published by Shahid Beheshti University of Medical Sciences.)
