“…20 As mentioned earlier, height and gender have an impact on NCS parameters and a failure to adjust references value to these elements may reduce the specificity and sensitivity of the NCS. 3,11,21 Most of our values were similar to four other similar published studies. 2,3,5,8,13,21,22,23 However, there were some differences, which could be attributed to different NCS techniques, machine settings, and demographic characteristics.…”

A notable dissimilarity was in the CMAP and the SNAP amplitudes because some studies used peak-to-peak measurement and others used baseline-to-negative peak measurements.…”

Background: nerve conduction study (NCS) is a neurophysiologic medical diagnostic test used commonly to evaluate the function of the peripheral nerves. It is an extension to the clinical examination and extremely useful to diagnose and document a peripheral nerve disorder, localize the lesion, and to establish underlying pathophysiology. Objective: The aim of this study is to evaluate the influence of gender on nerve conduction study values and to generate reference nerve conduction studies (NCS) data for the commonly tested nerves among healthy adults in Oman. Subjects and methods: This study was conducted in the Neurology Department at the Royal Hospital, a tertiary care hospital in Muscat-Oman, for a period of four years (from March 2015 until May 2019) which included a total of 143 (80 females and 63 males) healthy Omani subjects. Sensory and motor nerve conduction studies were performed to the Median, Ulnar, Peroneal and Tibial nerves to establish the normative data. Statistical analysis was performed using Minitab comparing the mean values of all NCS parameters for both genders. Results: Gender comparison concluded that Omani males have longer distal motor latencies for all of the tested nerves and slower motor conduction velocities for the lower limbs' nerves (p <0.005) than the females. While sensory latencies were significantly delayed in males as compared to Omani females for the upper limbs' nerves and the ensory nerve potential amplitudes in the upper limbs were greater in females (p<0.0001) than males. A normative data for distal latencies, conduction velocities and responses amplitudes for motor and sensory nerves were sat up for the first time for normal adult Omani population. Conclusion: Gender has a significant influence on distal latencies and conduction velocities of some peripheral nerves in healthy Omani adult subjects, suggesting that different cutoff values for the two genders may be needed for interpreting such studies. These differences could be related to anatomical (height and limbs' length gender differences) and/or physiological factors. Our normative data for nerve conduction study values are comparable to other published studies in the literature.

Background: Nerve conduction velocities (NCV) represent the most accurate methods to study the peripheral nerves owing to their ability in diagnosing nerve-related conditions. It helps to distinguish between a true nerve disorder and conditions where muscles are affected due to a nerve injury. However, there are considerable differences in reference values for NCV in different nerves with respect to region, gender, population, and various anthropological data such as age, height, body mass index, and temperature. They have to be kept in mind while doing nerve conduction studies as these anthropological factors vary according to the different geographical areas. Aim and Objectives: The aim of this study is to establish the electrophysiological data NCV for the right median nerve in normal healthy adults in Malwa region of Indore, district of Madhya Pradesh, and to study the effect of age, gender, and height on it along with relation among them. Materials and Methods: A total 118 healthy participants (38 females and 80 males) between the ages of 20 and 60 years, with no neurological problem were investigated at

Background and Aim: Overweight and obesity are major health problems leading to peripheral neuropathy. The exact mechanism of peripheral neuropathy in obesity is uncertain. However, increased oxidative stress and dyslipidemia are potential pathways. To find out the relationship between obesity and peripheral neuropathy in adults in Upper Egypt. Also, to clarify the role of dyslipidemia and oxidative stress in obesity-related neuropathy. Methods: Study groups are: normal weight, overweight and obese group (25 subjects in each group). All individuals underwent nerve conduction studies (NCS) of both median and ulnar nerves. In addition, lipid profile, TAC and MDA were measured in the serum. Result: We found significant increase in LDL, TG and MDA and significant reduction in HDL in obese compared to normal weight subjects. NCS showed significant slowing of NCV of right median motor and left median sensory, decrease in amplitude of ulnar motor nerves on both sides and right median motor nerve. Overweight group showed significant increase in LDL, TC and MDA compared to normal weight group. Conclusion: Our study suggested that obesity induces peripheral neuropathy. It also suggested that oxidative stress and dyslipidemia play an important role in the pathogenesis of obesity-related neuropathy.
