- Brief Summary
This study aims to test if transcranial direct current stimulation (tDCS) can be applied to boost the efficacy of constraint-induced movement therapy (CIMT) in children with HCP and examine brain mechanisms related to individual outcomes.
- Detailed Description
Currently, clinical treatment of hand/arm motor deficits in children affected by cerebral palsy is mainly rehabilitation and behaviorally oriented. Constraint-induced movement therapy (CIMT) has emerged as a frequently used rehabilitation intervention in children with hemiplegic cerebral palsy (HCP). In CIMT sessions, the unaffected upper limb is restrained with a cast or similar device, and the affected hand/arm is intensively and structurally trained. With different variations, such as constraint and intensity, CIMT has been demonstrated to be efficacious in improving hand-and-arm use in children with HCP. However, clinical outcomes across individuals who receive CIMT can show vast variation. How to improve the efficacy of CIMT and reduce individual variation will be of direct and profound clinical impacts. Motor deficits of children with HCP have a source origin of early brain injury, which often disrupts some regions of the brain and can cause changes in brain functions. Alteration or normalization of brain neuronal activities may influence motor functions in children with HCP and might boost the efficacy of CIMT. Transcranial direct current stimulation (tDCS), a type of non-invasive weak electric stimulation, has been demonstrated to be capable of influencing cognition and behaviors in abundant laboratory research tasks, hinting at potential clinical effects. Specific to the pediatric population with HCP, a few preliminary studies have tested the safety of tDCS when applied in children with HCP. This study will test how tDCS influences the efficacy of CIMT in children with HCP by comparing motor performances between two groups. The first group of children with HCP will receive anodal tDCS and CIMT while the second group of children with HCP will receive sham tDCS and CIMT during the intervention phase.

Group Intervention Description tDCS+CIMT tDCS Participants will receive concurrent anodal tDCS (20 minutes, 1mA\~2mA) and CIMT (2 hours) five days a week for three weeks in a row. sham+CIMT CIMT Participants will receive concurrent sham tDCS and CIMT (2 hours) five days a week for three weeks in a row. sham+CIMT sham tDCS Participants will receive concurrent sham tDCS and CIMT (2 hours) five days a week for three weeks in a row. tDCS+CIMT CIMT Participants will receive concurrent anodal tDCS (20 minutes, 1mA\~2mA) and CIMT (2 hours) five days a week for three weeks in a row.
- Primary Outcome Measures
Name Time Method fine manual dexterity With the first day of the intervention defined as day 1, this measure will be assessed in one of the three days before day 1, on day 15 or day 16 or day 17, and on day 181 or day 182 or day 183. It will be measured by the nine-hole peg test to assess the time one needs to place nine pins into a reservior.
gross manual dexterity With the first day of the intervention defined as day 1, this measure will be assessed in one of the three days before day 1, on day 15 or day 16 or day 17, and on day 181 or day 182 or day 183. It will be measured by the box and block test to assess how many blocks one can move from one box to another in one minute.
- Secondary Outcome Measures
Name Time Method finger touch sensitivity With the first day of the intervention defined as day 1, this measure will be assessed in one of the three days before day 1, on day 15 or day 16 or day 17, and on day 181 or day 182 or day 183. It will be measured with a two-point discriminator to assess the minimal displacement between two points of touch on fingertip one can perceive.
quality of upper extremity skill With the first day of the intervention defined as day 1, this measure will be assessed in one of the three days before day 1, on day 15 or day 16 or day 17, and on day 181 or day 182 or day 183. It will be subjectively assessed with the Quality of Upper Extremity Skill Test (QUEST) to measure functions and use of both upper limbs.
