It evaluates the electrical conduction ability of the nerves in the human body. Nerve conduction study is mostly conducted along with needle electromyography. It can measure the nerve as well as muscle function. So, the tests can detect the actual cause of pain or numbness in the limbs.

Lumbar Puncture

Lumbar Puncture

Lumbar puncture is also known as a spinal tap. It is used to detect the nervous system disorders causing problems with your arm. It is performed in your lumbar region (the lower back). During the procedure, a needle is inserted between your two vertebrae (the lumbar bones) to remove the cerebrospinal fluid. The sample of the CSF fluid can help in the detection of central nervous system disorders. The cerebrospinal fluid surrounds your brain as well as the spinal cord. It protects you from serious problems. So, you get protection from infections like meningitis or injuries. It also offers protection from multiple sclerosis or Guillain-Barre syndrome. The CSF fluid can also help in the detection of spinal cord or brain cancers.
