In biomedical applications, the similarity between a signal measured from an injured subject and a reference signal measured from a normal subject can be used to quantify the injury severity. A generalisation of the adaptive signed correlation index (ASCI) is proposed to account for specific signal features of interest and the trichotomisation of conventional ASCI extended to an arbitrary number of levels. In the context of spinal cord injury assessment, a computational example is presented to illustrate the enhanced resolution of the proposed measure and its ability to offer a more refined measure of the level of injury.
