Lateral asymmetry of motor unit number estimate (MUNE).
The aspects of lateral asymmetry of the peripheral nervous system have been investigated to a lesser extent than the aspects of lateral asymmetry in the central nervous system. We utilized a statistical method of quantitative MUNE to demonstrate lateral asymmetry of the motor units in healthy individuals, revealing higher values in the nondominant hand. Awareness of this phenomenon will improve the accuracy and reliability of this MUNE method when used in clinical trials.
