Study Details

Brief summary:

Children with a neurodevelopmental condition called developmental coordination disorder (DCD) struggle to learn motor skills and perform daily activities, such as tying shoelaces, printing, riding a bicycle, or playing sports. Evidence suggests that motor-based interventions combined with non-invasive brain stimulation to the motor cortex (transcranial direct-current stimulation, tDCS) has been effective in improving motor skills in children with cerebral palsy and other neurodevelopmental disorders, but few studies have examined tDCS in chidlren with DCD. The purpose of this randomized, blinded, sham-controlled interventional trial is to explore the effectiveness of anodal tDCS over M1 combined with a motor learning task in increasing motor skill learning in children with DCD.

Interventions and Outcome Measures

Arms

experimental: Active tDCS stimulation

tDCS will be applied over the left motor cortex at 1 mA for 30 min. The current will be ramped up to 1 mA over 45-60 s, held for 30 min, and ramped down to 0 mA over 45-60 s.

sham comparator: Sham tDCS stimulation

tDCS will be ramped up and held for only 60 s before it is slowly ramped down. This procedure, called the Fade-in-Short Stimulation-Fade out, has shown its reliability as an effective sham technique through making the same tolerability and transient scalp sensation as active stimulation in both adults (Ambrus 2012) and children (Ciechanski 2017).

Interventions

Motor Learning

Over three consecutive days, each child will perform five blocks of Purdue Pegboard Test: one block before, three blocks during, and one block after tDCS. Each block consists of three repetitions of Purdue Pegboard Test with the right hand. The children have to place pins into a pegboard as fast as they can in 30 seconds. It will take up to 10 minutes of brain stimulation time.

After the Purdue Pegboard Test, each child will receive cognitive-based intervention for printing skills for 20 minutes while receiving tDCS. "Printing Like a Pro!" (Montgomery 2017) -a cognitive approach to teaching printing to primary school-age children-will be used to teach letters which each child has the most difficulty printing legibly as identified on a formal assessment of handwriting-ETCH (manuscript) (Amundson 1995).

Primary outcome measure

  • Purdue Pegboard Test (Tiffin 1968) [ Time Frame: Before and after intervention; 6 weeks after intervention ]
