Profuse sweating is a common complaint among people with SCI and research has documented that a significant number of people with SCI experience periodic increased sweating associated with AD, orthostatic hypotension, or posttraumatic syringomyelia (Khurana 1987Jane et al. 1982Kramer and Levine 1997). Although the most common pattern in SCI is excessive sweating above the lesion level, sweating below the lesion level can also occur. These probably represent different autonomic mechanisms, the pathways of which have not yet been clarified.
