  2. Nerve conduction study - Wikipedia

    en.wikipedia.org/wiki/Nerve_conduction_study

    The interpretation of nerve conduction studies is complex and requires the expertise of health care practitioners such as clinical neurophysiologists, medical neurologists, physical therapists, or physiatrists. [6] [7] [8] NCS results provide information on whether a nerve conducts electrical signals at a normal speed and strength ...

  3. Small fiber peripheral neuropathy - Wikipedia

    en.wikipedia.org/wiki/Small_fiber_peripheral...

    Nerve conduction studies and electromyography are commonly used to evaluate large myelinated sensory and motor nerve fibers, but are ineffective in diagnosing small fiber neuropathies. [14] Quantitative sensory testing (QST) assesses small fiber function by measuring temperature and vibratory sensation. Abnormal QST results can be attributed to ...

  4. Uhthoff's phenomenon - Wikipedia

    en.wikipedia.org/wiki/Uhthoff's_phenomenon

    Peripheral nerve studies have shown that even a 0.5 °C increase in body temperature can slow or block the conduction of nerve impulses in demyelinated nerves. With greater levels of demyelination, a smaller increase in temperature is needed to slow down the nerve impulse conduction. [ 8 ]

  5. Thoracic outlet syndrome - Wikipedia

    en.wikipedia.org/wiki/Thoracic_outlet_syndrome

    The arterial type results in pain, coldness, and pallor of the arm. [2] TOS may result from trauma, repetitive arm movements, tumors, pregnancy, or anatomical variations such as a cervical rib. [1] The diagnosis may be supported by nerve conduction studies and medical imaging. [1]

  6. Nerve conduction velocity - Wikipedia

    en.wikipedia.org/wiki/Nerve_conduction_velocity

    To be specific, motor nerve conduction studies of the Median, Ulnar, and peroneal muscles should be performed, as well as sensory nerve conduction studies of the Ulnar and Sural nerves. [ 9 ] In patients with ALS, it has been shown that distal motor latencies and slowing of conduction velocity worsened as the severity of their muscle weakness ...

  7. Lambert–Eaton myasthenic syndrome - Wikipedia

    en.wikipedia.org/wiki/Lambert–Eaton_myasthenic...

    Chest X-ray showing a tumor in the left lung (right side of the image) The diagnosis is usually made with nerve conduction study (NCS) and electromyography (EMG), which is one of the standard tests in the investigation of otherwise unexplained muscle weakness. EMG involves the insertion of small needles into the muscles.

  8. Neuromuscular ultrasound - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_ultrasound

    Neuromuscular ultrasound refers to a field in medicine in which ultrasound is used to diagnosis and guide treatment for people with neuromuscular diseases.Neuromuscular ultrasound is often combined with electrodiagnosis, and particularly nerve conduction studies and EMG, to improve the accuracy of diagnosis and add anatomic information to the functional information obtained with electrodiagnosis.

  9. Polyneuropathy - Wikipedia

    en.wikipedia.org/wiki/Polyneuropathy

    Although diseases often are suggested by the physical examination and history alone, tests that may be employed include electrodiagnostic testing, serum protein electrophoresis, nerve conduction studies, urinalysis, serum creatine kinase (CK) and antibody testing; nerve biopsy is done sometimes.
