Distal site testing of sympathetic skin response (big toe) in diabetic polyneuropathy

Abstract The aim of this study was to determine whether the sympathetic skin response (SSR) recorded from the big toe is more sensitive than standard SSR recorded from the sole for the detection of sudomotor fiber dysfunction in diabetic neuropathy. We recorded big toe SSR (SSRBT) and plantar SSR (SSRP) in 17 diabetic patients with non-disabling neuropathy (group A), 13 patients with disabling neuropathy (group B) and 30 age-matched normal controls. With regard to controls, SSRP amplitude was reduced only in group B. In contrast, SSRBT amplitude was reduced in both groups of patients (p<0.0001). In 8 patients in group B, SSRBT was not recordable while the SSRP still persisted. Our results suggest that SS-RBT is a more sensitive test than SSRP in detecting distal sudomotor failure in patients with diabetic neuropathy.     

Autonomic neuropathy in mixed cryoglobulinemia

A retrospective, cross-sectional study was performed on a series of HCV-related mixed cryoglobulinemia (HCV-MC) patients to assess autonomic neuropathy (AN) and its relation to peripheral neuropathy (PN). Thirty consecutive patients affected by HCV-MC underwent clinical, neurological and electrodiagnostic examinations. Autonomic nervous system (ANS) involvement was assessed by functional cardiovascular tests and sympathetic skin response (SSR) evaluation. Sural nerve biopsy was performed in 10 patients with PN. All patients received steroids, 15 also received recombinant interferon-α2b (RIfn-α2b). PN occurred in 27 patients (90.0%) and AN in 4 (13.3 %) all with signs of PN. SSR was the autonomic test more frequently altered. Biopsy disclosed axonal degeneration more evident in the 4 patients with AN. Three out of 4 patients with AN received steroids and rIFN-α2b and 1 steroids alone. In our study on HCV-MC, it was concluded that AN can occur also without dysautonomic symptoms, SSR appears to be one of the optional tests to use together with dysautonomic tests to identify AN and finally PN and AN do not seem to be positively influenced by addition of rIFN-α2b to steroid treatment.

Sympathetic skin response (SSR) is abnormal in multiple sclerosis

As the function of the autonomic nervous system is often compromised in multiple sclerosis (MS), different standardized tests are used to detect disseminated abnormalities in cardiovascular autonomic functions. Sympathetic skin response (SSR), a slow wave generated in deep layers of the skin, is induced by reflex activation of sudomotor sympathetic efferent fibers. SSR was studied in 70 patients classified into different categories according to the diagnostic criteria for MS. We also obtained pattern reversal visually evoked potentials and brainstem auditory evoked potentials as well as somatosensory evoked potentials (by median and posterior tibial nerve stimulation). SSR was abnormal in 66 patients (94.2%), including abnormal foot latency with normal hand latency in 30 (42.8%), delayed foot and hand latencies in 30 (42.8%), and no response in 6 (8.6%). The percentages of SSR abnormalities were similar in the different patient categories. Pathological SSR were more common than abnormal evoked potentials in suspected and probable MS. SSR appears to be a simple and effective means of assessing sympathetic sudomotor outflow disturbances in MS, providing a valuable addition to current electrophysiological procedures for the detection of MS lesions.© 1995 John Wiley &Sons, Inc.     

Sympathetic skin response in patients with chronic renal failure

Sympathetic skin response (SSR) was measured in 20 normal healthy subjects and in 22 patients with chronic renal failure on regular hemodialysis, and its correlation with abnormalities of sensorimotor nerve conduction study and clinical autonomic symptoms was investigated. Nerve conduction studies (NCS) were abnormal in 17 of 22 patients (77.3%), and SSR was absent in 14 of 22 patients (63.6%). Patients were divided into three groups based on their SSR response: patients with normal SSR (n:8, 36.4%), patients with absent SSR in the foot only (n:9, 40.9%), and patients with absent SSR in both hand and foot (n : 5, 22.7%). Good correlation between abnormalities of NCS and absent SSR was observed. No correlation was noted between patient age, sex, duration of hemodialysis, duration of renal failure history, and absent SSR. However, statistically significant correlation was found between mean amplitude of the foot SSRs and sensorimotor nerve conduction velocities, and weekly frequency of hemodialysis.     

Sympathetic skin responses (SSRs) in monofocal brain lesions: topographical aspects of central sympathetic pathways

Lesions of the central sympathetic pathways are likely to be of clinical relevance. In patients with acute stroke, in particular, they may be responsible for the partially deleterious cardiac arrhythmia. There is little knowledge of the central organization of sympathetic pathways above the brainstem level for both cardio-efferent and sudomotor fibers. We studied the sympathetic skin response (SSR) in 29 patients with brainstem stroke or infarction in the territory of the middle cerebral artery (MCA) in order to evaluate the pathways mediating emotional sweating. In 24 patients (82.8%) the SSR was pathological. These abnormalities were bilateral with no clear asymmetry in 10 patients (34.5%), bilateral with marked contralateral pathology in 8 patients (27.6%), purely contralateral in 5 patients (17.2%) and purely ipsilateral in one patient (3.5%). Bilateral abnormalities were more frequent and more marked in brainstem than in MCA stroke. This is probably indicative of a more generalized sympathetic dysfunction. In contrast, contralateral abnormalities were more pronounced in MCA than in brainstem infarcts. Our results show that sympathetic skin responses are suppressed in the majority of stroke patients. Asymmetric responses may indicate that sudomotor fibers mediating emotional sweating have their origin or receive input from the contralateral MCA territory.     

Axon Count and Sympathetic Skin Responses in Lumbosacral Radiculopathy

Background and Purpose

Electrodiagnostic studies can be used to confirm the diagnosis of lumbosacral radiculopathies, but more sensitive diagnostic methods are often needed to measure the ensuing motor neuronal loss and sympathetic failure.

Methods

Twenty-six patients with lumbar radiculopathy and 30 controls were investigated using nerve conduction studies, motor unit number estimation (MUNE), testing of the sympathetic skin response (SSR), quantitative electromyography (QEMG), and magnetic resonance myelography (MRM).

Results

Using QEMG as the gold standard, the sensitivity and specificity of MUNE for the abductor hallucis longus muscle were 71.4% and 70%, respectively. While they were 75% and 68.8%, respectively, when used MRM as gold standard. The sensitivity and specificity of MUNE for the extensor digitorum brevis muscle were 100% and 84.1%, respectively, when the peroneal motor amplitude as the gold standard. The SSR latency was slightly longer in the patients than in the controls.

Conclusions

MUNE is a simple and sensitive test for evaluating autonomic function and for diagnosing lumbosacral radiculopathy in patients. MUNE could be used routinely as a guide for the rehabilitation of patients with radiculopathies. SSR measurements may reveal subtle sympathetic abnormalities in patients with lumbosacral radiculopathy.

Cardiovascular autonomic function and sympathetic skin response in chronic inflammatory demyelinating polyradiculoneuropathy

Quantitative cardiovascular autonomic function tests (AFTs) and sympathetic skin response (SSR) were performed in 12 patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Parasympathetic autonomic function was examined by Valsalva ratio and R-R interval variation during rest and deep breathing. Sympathetic autonomic function was evaluated by blood pressure responses to sustained handgrip and active standing. Using quantitative AFTs, subclinical autonomic dysfunction was demonstrated in three (25%) patients. Abnormal SSR was seen in six (50%) patients. Thus, mild autonomic dysfunction is present in many CIDP patients. The autonomic abnormalities involve parasympathetic or sympathetic components; in the sympathetic nervous system, both vasomotor and sudomotor fibers may be involved.
