The neural basis underlying motor performance in children using a prosthesis has been severely understudied resulting in minimal empirical evidence. With the use of low-cost 3D printed prosthetics, the purpose of this study is to examine the assessment of primary motor cortex activation and the representation of gray and white matter in a child with congenital limb loss. This will be accomplished by cross-examining results from fNIR and Anatomical Magnetic Resonance Imaging (MRI). The proposed research uses anatomical MRI to test if children with unilateral congenital partial hand reductions demonstrate less gray and white matter in the motor representation zones. Moreover, the proposed research will focus on an assessment of motor performance using continuous and discrete tasks with a robotic manipulandum. Assessment of motor performance and neural networking are critical to increasing our limited knowledge of how the child increases the number of motor repertoires.
