Impact of age, height, weight and body mass index on sural sensory and soleus H-reflex study measures in healthy central Indian population

Introduction: Sural sensory nerve conduction studies and Soleus H-reflex studies are affected earliest in systemic illness like diabetes mellitus. Age, sex, height and BMI are associated with nerve conduction study variables. Association of Soleus H-reflex study variables including H wave maximum amplitude and H/M ratio have been rarely explored yet. Aims and objectives: To evaluate the impact of anthropometric measures on sural sensory and soleus H-reflex study variables. Design: A cross sectional study. Material and methods: Fifty healthy participants (47 male and 3 female) with mean age 33.02 years and age range 21-60 years underwent electrophysiological evaluation (sural sensory and soleus H-reflex study). Sural SNAP amplitude, CV, H wave minimum latency, H wave maximum amplitude and H/M ratio values were obtained. Results: Statistically significant correlation (p value 0.05) but fixed trends were observed between anthropometric measures and sural SNAP amplitude or H wave minimum latency. No correlation was observed between anthropometric measures and sural CV or H/M ratio or H wave maximum amplitude. Conclusion: Study concluded that as age advances H wave minimum latency prolongs. There are no significant height, weight, BMI related changes in sural and soleus H-reflex study.
