How do you test for leprosy nerves?

Procedure for palpation of a nerve Look at the patient’s face while palpating the nerve gently with the pulp of the finger (not the tip of the finger) to elicit tenderness.

Which nerves are affected in leprosy?

Leprosy does not affect the central nervous system. However, it can affect the peripheral nervous system (PNS) (sensory, motor and autonomic nerves) by: sensory nerve damage – when the sensory nerves are damaged, they cannot register pain.

Which nerve is most commonly involved in leprosy?

Mononeuritis is the most common presentation of leprosy, and the nerves in the upper limbs are more often affected than those of the lower. The most commonly involved nerves are the ulnar, median, posterior auricular, superficial radial, common fibular, superficial fibular and posterior tibial 4.

What is peripheral nerve thickening?

Thickening of peripheral nerve trunk is one of the cardinal features of leprosy. Localised tumours arising from sheaths of peripheral nerves causing nerve thickening can sometimes be seen in neurofibromatosis.

How do you palpate peripheral nerves?

NERVES BY PALPATION Attempts to palpate such nerves are best made using the tips of the index, middle and ring fingers rolled backwards and forwards across the long axis of the nerve. Sometimes you can try to pick up the nerve between the thumb and middle finger as in the case of the ulnar nerve in the upper arm.

What is peripheral nerve involvement?

The peripheral nerves of the arm communicate neural signals with sensitive end organs in the skin of the hand. These end organs tell the body what it “feels” . The neural signals make the muscles of the arm and hand operate the elbow, wrist and fingers.

Which nerves are thickened in leprosy?

Leprosy is a common cause of neuropathy. Thickened peripheral nerves are one of the cardinal features. Ulnar and common peroneal nerves are the most frequent thickened nerves.

How does leprosy cause peripheral neuropathy?

Leprosy, a chronic infectious disease caused by Mycobacterium leprae, identified by G. H. A. Hansen in 1873, is one of the most common treatable peripheral neuropathy in the world. Leprosy causes a ‘mononeuritis multiplex’ of immunological origin that results in autonomic, sensory and motor neuropathy 1.

How do you check your nerves?

These tests may include:

  1. Nerve conduction study. This test measures electrical nerve impulses and functioning in your muscles and nerves through electrodes placed on your skin.
  2. Electromyography (EMG).
  3. Magnetic resonance imaging (MRI).
  4. High-resolution ultrasound.
