2 Non-Surgical Procedures in Neuropathy

Aside from the two common electrodiagnostic tests perform in the presence of mild to severe neuropathy – Electromyography and Nerve Conduction Velocity Test, there are other two non-surgical procedure to further identify root cause of unexplained numbness.

Cerebrospinal Fluid Test

This is also known as lumbar puncture and is the most typical procedure of collecting spinal fluid from a patient.  The spinal fluid is usually colorless and acts as buffer covering the brain and spinal cord.  Any changes found, qualitatively or quantitively, signals mild to serious neuropathy.

Any presence of bacteria or increased amount of white blood cells causes cloudiness in the fluid and therefore indicating infection either in the brain or in spinal cord.

Purpose of Cerebrospinal Fluid Test

This examination identifies presence of autoimmune disorder such as Guillain-Barré Syndrome or Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).  Patients attacked by these disorders would show more protein in their spinal fluid than normal individuals. More information on formigamento nas mãos click here.

Procedure of Cerebrospinal Fluid Test

The patient is being injected with small anesthetic in the middle of the lower back while he/she is positioned lying on his/her side. After which, a long, thin needle is inserted in the spinal canal.  As the fluid is being collected, CSF pressure is also being measured.

Quantitative Sensory Testiing (QST)

This method measures the detection level of a sensory stimuli which is accurately calibrated.  Three stimuli are chosen – vibratory, thermal or painful- because they relate to specific neuroanatomic pathways.

Purpose of QST

This methodology assesses the severity of a nerve damage most specifically in the small nerve endings.  This would also tell how the neuropathycondition of the patient responds to the treatment being given.

Procedure of QST

This test involves a computer system which tells how the nerves being tested respond to vibration and applied changes in temperature.  The results are being compared to reference standards that are in normal individuals.
