In the case of children with dysgraphia, a good number of them will not be able to write with finger movement despite efforts and intervention. For such children the wrist movement tried. However, this would require ergonomic adaptation of pencil and other writing, drawing and painting tools.
The following conditions for the hand would be needed for writing with wrist movement
1. External or assistive aid to get the writing tool clamped with thumb and next two fingers - index and middle fingers
2. Size of the tool to facilitate flexing of the wrist to activate forearm gross muscle to make wrist movement writing-assisting
3. Positioning of index or middle finger to provide optimum pressure on the paper to get the impression on the writing surface
There is need for interventions to make children with dysgraphia to acquire assisted positioned of fingers on writing tool with extended and curved bending for movement of hand from wrist by flexed forearm muscle.
My experience informs that firm assisted hold on fingers either by the teacher or ergonomically designed writing device facilitating forearm muscles provides movement to wrist and hand for better control on writing. The design of pencil ergonomic pencil should be able to provide a tool-hooked wrist and intervention must provide enough movement therapy to enable the dysgraphic child to write with wrist movement.
