  2. Multifocal motor neuropathy - Wikipedia

    en.wikipedia.org/wiki/Multifocal_motor_neuropathy

    Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken.The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.

    Its size ranges from 0.5 (typically) to 1 mm in diameter and is used in the control of its jet propulsion system. The fastest recorded conduction speed of 210 m/s, is found in the ensheathed axons of some pelagic Penaeid shrimps [ 69 ] and the usual range is between 90 and 200 meters/s [ 70 ] ( cf 100–120 m/s for the fastest myelinated ...

    The following table describes the IENFD values in males and females of a 3 mm biopsy 10 cm above the lateral malleolus (above ankle outer side of leg). [21] Any value measured below the 0.05 Quantile IENFD values per age span, is considered a reliable positive diagnosis for small fiber peripheral neuropathy. [21]

  5. Peripheral neuropathy - Wikipedia

    en.wikipedia.org/wiki/Peripheral_neuropathy

    Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).

  6. Hoover's sign (leg paresis) - Wikipedia

    en.wikipedia.org/wiki/Hoover's_sign_(leg_paresis)

    Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.

  7. Focal neurologic signs - Wikipedia

    en.wikipedia.org/wiki/Focal_neurologic_signs

    Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]

    en.wikipedia.org/wiki/Two-point_discrimination

    Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one.It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is.
