INTRODUCTION: Two main hypotheses have been proposed for the pathophysiology of long thoracic nerve (LTN) palsy: nerve compression and nerve inflammation. We hypothesized that critical reinterpretation of electrodiagnostic (EDX) studies and MRIs of patients with a diagnosis of non-traumatic isolated LTN palsy could provide insight into the pathophysiology and, potentially, the treatment. MATERIAL AND METHODS: A retrospective review was performed of all patients with a diagnosis of non-traumatic isolated LTN palsy and an EDX and brachial plexus or shoulder MRI studies performed at our institution...

Acquired myasthenia gravis (MG) is relatively uncommon in cats. In humans, MG may be associated with other immune-mediated disorders, in particular polymyositis (PM). In this study, we described in-depth electrodiagnostic findings and pathological changes in muscles of cats diagnosed with MG, and assessed the presence of concurrent PM. Six cats with confirmed acetylcholine receptor antibody seropositive MG, and two suspected cases with clinical signs and electrophysiological changes consistent with MG, were reviewed...

One of the most common referrals to the electrodiagnostic (EDX) laboratory is to confirm a clinical impression of carpal tunnel syndrome (CTS). The EDX studies are valuable in localizing median nerve abnormalities to the wrist, grading its severity, and excluding other condition that can mimic or coexist with CTS. However, there are many clinical and EDX pitfalls that can lead to misdiagnosis. Careful clinical assessment and attention to technical factors and details of the EDX techniques are fundamental for the quality and accurate interpretation of the study...

PURPOSE: We investigated the spontaneous recovery of non-operated traumatic brachial plexus injury (BPI). METHODS: A total of 25 cases of non-operated traumatic BPI were analysed by retrospective review of medical records; in all cases, consecutive electrodiagnostic studies (ES) were conducted from 1 to 4 months and 18 to 24 months post-trauma. Injury severity was assessed using a modified version of Dumitru and Wilbourn's scale (DWS) based on ES. Spontaneous recovery of brachial plexus components per subject was analysed using Wilcoxon's signed-rank test...

In addition to the more common carpal tunnel and cubital tunnel syndromes, orthopaedic surgeons must recognize and manage other potential sites of peripheral nerve compression. The distal ulnar nerve may become compressed as it travels through the wrist, which is known as ulnar tunnel or Guyon canal syndrome. The posterior interosseous nerve may become entrapped in the proximal forearm as it travels through the radial tunnel, which results in a pain syndrome without motor weakness. The median nerve may become entrapped in the proximal forearm, which can result in a variety of symptoms...

Carpal tunnel syndrome (CTS) is a focal compressive neuropathy of the median nerve at the level of the wrist. CTS is the most common type of compressive neuropathy that occurs in the upper extremity. Typically, patients with CTS have paresthesia, pain, and numbness in the radial three and one-half digits. Nighttime symptoms are more common earlier in the disease process, with daytime symptoms becoming more frequent as CTS progresses. Electrodiagnostic studies may be performed to confirm a diagnosis of CTS or to obtain a baseline before surgical treatment; however, electrodiagnostic studies may be normal in a subset of patients who have CTS...
