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.
