Spinal reflex evaluation helps to narrow down further the lesion localisation by testing the integrity of the cervicothoracic intumescence (C6 – T2 segments) and lumbosacral intumescence (L4 – S3 segments) as well as respective segmental sensory and motor nerve, that form the peripheral nerve, and the muscles innervated. Lesions at the level of these intumescences or affecting the peripheral nervous system result in LMN signs in the muscles innervated i.e. loss of segmental spinal reflexes as we
