  • Title: Added sampling improves reproducibility of multipoint motor unit estimates.
    Author: Goyal N, Salameh JS, Baldassari LE, David WS.
    Journal: Muscle Nerve; 2010 Jan; 41(1):114-6. PubMed ID: 19813198.
    Abstract:
    Motor unit number estimation (MUNE) has been used to track motor unit attrition. Studies have used the modified multiple-point stimulation (MPS) technique, collecting three surface motor unit action potentials (sMUAPs) from 3 sites to calculate MUNE. Factoring additional sMUAPs should theoretically improve reproducibility, but the optimal number has not been defined. We evaluated the effect of increased sMUAP sampling on test-retest reproducibility of the modified MPS MUNE technique and found that MUNE reproducibility increased with additional sampling.
