605 Possible Causes for Inability to Supinate Forearm, Slow Nerve Conduction Velocities

  • Brachial Plexus Neuropathy

    Anesthesiologists attending to the patient in PACU noticed an inability of the patient to lift his right arm, abduct the shoulder, flex or supinate the forearm.[]

  • Peripheral Neuropathy

    Nerve conduction studies can distinguish demyelinative neuropathy (slowing of conduction velocity or conduction block) from axonal neuropathy (low-action potential amplitudes[] Nerve conduction studies assess the shape, amplitude, latency, and conduction velocity of an electrical signal conducted over the tested nerve.[] Axonal loss leads to lower amplitudes, and demyelination causes prolonged latency and slow conduction velocity.[]

  • Carpal Tunnel Syndrome

    Median nerve conduction velocities are slowed along the wrists and hands of people with CTS.[] Picture of carpal tunnel syndrome The diagnosis is strongly suggested when a nerve conduction velocity test is abnormal.[] Ultrasound and MRI are useful adjunctive tests to gather additional information if the nerve conduction test is equivocal or negative and a high degree of suspicion exists[]

  • Demyelinating Disease

    This will give a falsely slow conduction velocity.[] - Nerve conduction velocity slowed because of multifocal destruction of myelin segments involving many axons within a peripheral nerve What abnormalities would you see in[] Using this hypothesis in segmental demyelinating disease, latency alone is a better parameter of nerve conductivity than nerve conduction velocity, and serial latencies may[]

  • Ulnar Nerve Entrapment

    An electromyographic (EMG) investigation revealed slowing of the motor conduction velocity in the ulnar nerve across the elbow.[] The most reliable finding is slowing of the ulnar across-elbow motor nerve conduction velocity to less than 50 m/sec while recording from the abductor digiti minimi muscle[] Examining the electrical activity may help a physician study any injury to the ulnar nerve within the elbow Nerve conduction velocity (NCV) of ulnar nerve: Nerve conduction[]

  • Chronic Inflammatory Demyelinating Polyneuropathy

    Although the patient noticed little muscle weakness, an electrophysiological study demonstrated slow conduction velocities and prolonged distal latencies, with definite conduction[] Primary demyelination leads to nerve conduction velocity slowing, distal latency prolongation, and F-wave latency prolongation or absence.[] Young age at onset, duration of symptoms less than 6 months, slight neurologic impairment, and mild slowing of nerve conduction velocities have been associated with a favorable[]

  • Guillain-Barré Syndrome

    Nerve conduction analysis will reveal slow nerve conduction velocities due to the damage to the nerve.[] Initial electrodiagnostic testing detects slow nerve conduction velocities and evidence of segmental demyelination in two thirds of patients; however, normal results do not[] If Guillain-Barré syndrome is suspected, patients should be admitted to a hospital for electrodiagnostic testing (nerve conduction studies and electromyography), CSF analysis[]

  • Peroneal Nerve Compression Neuropathy

    Slowing of peroneal nerve conduction velocities at the fibula head may or may not be detected.[] There was a focal slowing of the maximum nerve condition velocity across the neck of the fibula.[] Amplitudes can also be compared with the contralateral unaffected peroneal nerve or if necessary to normal control values.[]

  • Charcot Marie Tooth Disease

    HMSN1 is the most common form of hereditary neuropathy, characterized by severely and uniformly slowed nerve conduction velocities and primary hypertrophic myelin pathology[] The EMG and NCV were consistent with demyelination and slow nerve conduction velocities.[] Electrophysiological studies distinguish two major types – the demyelinating form, which is characterized by symmetrically slowed nerve conduction velocity (NCV; usually 1[]

  • Hypertrophic Interstitial Neuropathy

    nerve conduction velocities ( Many phenotypic variants have been reported.[] Nerve conduction velocities are slow, and distal latencies are prolonged. Segmental demyelination and remyelination occur. Enlarged peripheral nerves may be palpated.[] […] as an autosomal recessive form: HMSN type III or Dejerine-Sottas disease: a severe, demyelinating neuropathy, presenting in infancy with delayed motor development, very slow[]
