Background: Evidence is accumulating that patients with polyneuropathy may present with normal clinical deep tendon reflexes (C-DTR). There are few studies that assessed the diagnostic utility of electromyographically recorded DTR (Er-DTR) in patients with polyneuropathy.

Objectives: The objectives of this study were twofold: (i) to evaluate the prevalence of preserved C-DTR in polyneuropathy; (ii) diagnostic value of Er-DTR latency measurement in patients with polyneuropathy.

Objective: To describe temporal profile of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) in patients with definite, relapsing multiple sclerosis (MS).

Background: Peripheral demyelinating neuropathy has been rarely reported in association with central nervous system demyelinating disorder indistinguishable from MS.

Methods: In addition to usual diagnostic studies for CIDP and MS in all 5 patients, we studied proximal segments of nerves using deep tendon reflex latency measurements of biceps reflex, patellar reflex, and ankle reflex.

Article Synopsis
  • Small-fiber neuropathy (SFN) is identified through clinical signs and specific small-fiber tests rather than standard nerve conduction studies, which are normal in these cases.
  • This study assessed deep tendon reflex (DTR) latency as a diagnostic tool for SFN by measuring reflexes in 18 SFN patients and 38 control subjects, finding that latencies were significantly longer in SFN patients across all tested reflexes.
  • Results show that DTR latency measurements are reliable and can indicate subclinical large fiber involvement, making it a useful method for diagnosing mild cases of SFN.

Objective: To examine the autonomic nervous system functions in patients with Huntington disease.

Background: Although patients with Huntington disease frequently experience vegetative symptoms, it is not clear if there is dysfunction of the autonomic nervous system.

Methods: Sympathetic skin response (SSR) latency and amplitude from both palms and soles and R-R (heart rate) interval variation (RRIV) at rest and during the Valsalva maneuver were examined in 22 patients and 21 age-matched controls.
