Testing can continue caudally to transfer to the thorax testing the cutaneous trunci reflex over the mid‐third of the lateral thorax, again with forceful stimuli. There is a variable region over the point of the shoulder, about the C7–T3 dermatomal region, where neither responses are well obtained, and the cutaneous trunci reflex usually fades in the caudal thoracic region. Flexion, extension, and lateral bending of the thoracolumbosacral vertebral column is then conveniently tested with the instrument used to firmly stroke the lateral dorsum from the withers to the caudal gluteal region. Again, the two‐pinch technique is used to test lateral thoracic dermatomes and to test limb autonomous zones for areas of hypalgesia if there is any evidence whatsoever of a reflex or final motor neuron lesion. Regional loss of muscle bulk, bony asymmetry, and areas of sweating also should invoke detailed scrutiny.
