(Fig. 151) which did not occur in complete lesions below T5/6. These are discussed in
more detail in the chapter on pregnancy and labour, for the autonomic hyperreflexia
found in the spinal man is by no means confined to hyperactivity of the bladder.
Outbursts of sweating and pilo-erection are also regular components of the autonomic
hyperreflexia due to bladder distension. In cervical and upper thoracic lesions sweating
usually started over the forehead and face (upper lip) either bilaterally or unilaterally,

spreading later to both arms and chest, tapering off to Ty/8 but rarely progressing beyond
Tio dermatome. Fig. 152 demonstrates the profuse reflex sweating at the height of
bladder distension in a man with a transection of the cord below C8/Ti due to gunshot
injury. In the case of T3/4 lesion, shown in Fig. 144, reflex sweating started at the level
of the lesion spreading to both axillae and tapering off to T8 (Fig. 153). Fig. 154 shows the
final stage of reflex sweating in a complete lesion below TS involving the trunk down to
Tn but also partly the legs and proximally the medial parts of the arms including the
