Gender based variation in simple muscle twitch.
Pak J Physiol Jan ;11(4):30-1.

Background: Muscle twitch or fasciculation is an involuntary action marked by small muscle contractions as a result of action potential. Aim of this study was to determine the gender based variation in the current required to develop muscle twitch. Methods: This cross-sectional study, using convenient sampling procedure was carried out in the Physiology department LUMHS, Jamshoro. The study was carried out on PowerLab® with stimulating bar electrode as transducer. Fifty male and fifty female students of 1st and 2nd year MBBS were enrolled in the study. Data was analysed on MS Excel 2013. Results: The mean current required for muscle twitch to develop was more in case of males (67.064±105 mA) than that of females (41.41±0.69 mA). Conclusion: The skeletal muscles of the females require less current to develop muscle twitch.
