The Neurological Hand Deformity Classification: Construct validity, test-retest, and inter-rater reliability

The Neurological Hand Deformity Classification (NHDC) is an impairment-based tool that classifies hand deformity into one of two ordinal scales: flexion or extension deformities. Classification is made from live observation or from recorded video footage. Differentiation between the levels is determined by wrist position and wrist and finger movement.
