Involvement of peripheral vasomotor fibres in carpal tunnel syndrome.

Autonomic dysfunction in idiopathic carpal tunnel syndrome

“…Although more sensitive autonomic tests are available, these tests are not practical in the routine evaluation of CTS. 1 The presence of autonomic symptoms correlated with worsening electrophysiologic findings. Clinical severity and duration of disease were, however, poor predictors of dysautonomia in our study.…”

“…Involvement of sympathetic fibers in CTS has also been demonstrated by the digital plethysmography technique. 1 Autonomic symptoms were common in our prospectively studied series (55%). Swelling of fingers and dry palms were the most common autonomic symptoms.…”

“…Though our numbers are comparable to other studies that have examined the presence of dysautonomia and the role of SSR in CTS, they are modest given our objective. 1,5,6,8,11,13,14,18,20 Our groups consisted predominantly of women. Community based studies suggest that there is a female preponderance in CTS.…”

EMG vs. Thermography in Severe Carpal Tunnel Syndrome

“…Our neural network was used on a group of patients with predominantly bilateral impairment, and the threshold for successful classification was set at 80%. The assessment of the autonomous nervous system, in MN entrapment, was evidenced only by few authors (Aminoff, 1979;Verdugo et al, 2004;Verghesse et al, 2000). As a matter of fact, the incidence of these symptoms is not completely clear both in healthy people and in people with some other hand pathology.…”

“…In CTS, including rare cases of painful MN entrapment, we can come across any of the pathological samples mentioned above. However, further attention is required for the interpretation of results, because changes in vasomotor tonus are not exclusively the result www.intechopen.com of stimulation of sympathetic nerve fibres (Aminoff, 1979;Ochoa & Verdugo, 1995;Ochoa, 2002). And namely: 1.…”
