EFFECT OF AGE AND BODY MASS INDEX ON SENSORY NERVE CONDUCTION

Author(s): L. Aswathy

BACKGROUND Nerve Conduction Study (NCS) and Needle Electromyography (EMG) are the main electrodiagnostic assessments for peripheral nerves. Nerve conduction study helps in knowing the extent and distribution of neural lesions. The sensory nerves studied in the lower limb are the sural nerve and the common peroneal nerve. The sensory nerve dysfunctions usually start in the lower limbs. Sural nerve study in systemic illness like diabetes mellitus shows axonal neuropathies. It also has higher diagnostic value. Aging is the process of becoming older, a process that is genetically determined and environmentally modulated. As age increases the nerve conduction velocity decreases. Along with age, Body Mass Index (BMI) is also an important factor to be taken into consideration. The objective of the study is to assess the effect of age and BMI on sensory nerve conduction study
