It is widely accepted that nerve conduction study (NCS) parameters changes with age, particularly in median nerve across carpal tunnel .These changes occurs at a greater rate in median than in ulnar nerve. Subclinical micro trauma to the median nerve through the carpal tunnel over several decades may account for the more pronounced influence on the median nerve compared with ulnar nerve at wrist. It is therefore possible that the conduction velocity of ulnar nerve across elbow may also change differently with advancing age. A prospective study of motor nerve conduction velocity across elbow were performed in170 healthy human subjects of both sexes. It was observed that motor conduction velocity of ulnar nerve in different age groups was almost same. The difference between the different age group was not statistically significant. The present study on ulnar nerve shows non linear changes in nerve conduction velocity across elbow with age
