BACKGROUND Kinematic studies of abnormal upper extremity (UE) motion provide the unique and valuable perspective of motion analysis during simulated functional tasks. However, they require comparison with healthy control data. Obtaining this control data usually entails testing a healthy population, which can be costly and time consuming, requiring separate(More)
Two square 0, 1 matrices A, B are a pair of Lehman matrices if AB T = J + dI, where J is the matrix of all 1s and d is a positive integer. It is known that there are infinitely many such matrices when d = 1, and these matrices are called thin Lehman matrices. An induced subgraph of the Johnson graph may be defined given any Lehman matrix, where the vertices(More)
