25 Possible Causes for Nerve Amplitudes of Peroneal Nerve Reduced

  • Mitochondrial Membrane Protein-Associated Neurodegeneration

    BACKGROUND: Mitochondrial membrane protein associated neurodegeneration (MPAN) is the third most common subtype of neurodegeneration with brain iron accumulation (NBIA) and caused by mutations of the orphan gene C19ORF12 encoding a transmembrane mitochondrial protein. Like other NBIA disorders, the hallmark of[…][]

  • Anti-NMDA Receptor Encephalitis

    Motor nerve conduction velocity was decreased in the tibial and peroneal nerves. F-wave amplitudes were reduced in the tibial nerve.[]

  • Lipedema

    The amplitude of the sensory nerve action potential was reduced in the left superficial peroneal and both sural nerves.[] The amplitude of the motor nerve action potential for both deep peroneal nerves, which were recorded in the short extensors of the toes, was reduced.[] There was no nerve action potential in the right superficial peroneal nerve.[]

  • Hereditary Gelsolin Amyloidosis

    Routine NCSs on the right extremities revealed reduced CMAP amplitude and conduction velocity and delayed terminal latency in the right peroneal nerve, and a mildly reduced[] In addition, blink reflex tests showed borderline to mildly prolonged latencies of ipsilateral R1 and R2 and contralateral R2 waves with facial nerve stimulations on either[]

  • Mononeuritis Multiplex

    Nerve conduction study using surface electrodes showed low amplitude Compound muscle action potential (CMAP) of the right ulnar nerve with reduced conduction velocity and[] […] absent F waves; CMAPs were absent in bilateral common peroneal and posterior tibial nerves.[] Bilateral median nerve Sensory nerve action potentials (SNAP) had reduced amplitude while right ulnar and bilateral sural nerve SNAPs were absent.[]

  • Hurthle Cell Carcinoma

    Nerve conduction studies (NCS) showed reduced CMAP amplitude, with right more than left peroneal nerve, inelicitable femoral CMAP and normal response for sural nerves and[]

  • Congenital Pain Insensitivity

    […] and common peroneal and tibial nerves in lower limbs.[] Her sensory NCS revealed reduced s ensory n erve a ction p otential (SNAP) amplitudes but normal conduction velocities and sensory peak latencies in median, ulnar and radial[] Motor NCS revealed normal compound muscle action potential amplitudes, distal motor latencies, and conduction velocities in median, ulnar and radial nerves in upper limbs[]

  • Sciatic Neuropathy

    These were found to be a polyphasic and reduced amplitude in the peroneal nerve of 1.3 mV.[] Electrodiagnostic studies were performed three months later that included electromiography and motor nerve conduction studies.[]

  • Hepatitis A

    The findings of motor nerve conduction studies showed markedly reduced amplitudes of compound muscle action potentials in bilateral peroneal, and posterior tibial nerves,[]

  • Delayed Motor Nerve Conduction Velocity

    A motor conduction study revealed a reduced compound muscle action potential amplitude, slowed nerve conduction velocity, delayed distal latency , and prolonged F latency[] […] over the median, ulnar, tibial, and peroneal nerves.[]
