The Effects of Alcohol on the H-reflex in Adults

초록

[Purpose] The purpose of this study was to compare the H-reflex in participants before and after alcohol intake. [Subjects] The aim of this study was to investigate the impact on the H-reflex after alcohol intake by performing experiments with adult subjects who were 19 to 27 years of age. Thirty subjects (men=15, women=15) were arranged into three groups. There were 10 people in each group. [Method] The three groups consumed 0.05 mL/kg, 0.4 mL/kg and 0.8 mL/kg of alcohol, respectively. An MP150 (BIOPAC Systems, Inc., Goleta, CA, USA) was used to obtain the values measured by electromyography (EMG) using Ag-Ag/Cl measurement electrodes (BIOPAC, diameter of 2 cm). Waves were measured to assess the action potential of the central neuron. [Results] In Group I, the H-reflex was 4% lower after 6 hours compared with before alcohol intake. In Group II, it was 10% lower after 6 hours compared with before alcohol intake. In Group III, it was 31% lower after 6 hours compared with before alcohol intake. H-reflex was mostly decreased in the three groups after alcohol intake. [Conclusion] Drinking may cause problems with ADL. The results also show that having alcohol before work that requires intensive concentration would cause more accidents and injuries, as alcohol affects the human H-reflex. The amount of alcohol intake was found to have an influence on the H-reflex.
