Currently, patients must self-report side effects during implantation surgery and device programming\u2014a subjective and inconsistent process that may delay optimized treatment or result in suboptimal therapy. Motor evoked potentials (mEP), the use of electromyography to record DBS-induced muscle activation, offer a promising biomarker for objective motor side effect detection.\n                    <jats:italic>Approach.<\/jats:italic>\n                    We present an automated algorithmic procedure for mEP detection and quantification.\n                    <jats:italic>Main results.<\/jats:italic>\n                    First, we design and evaluate a series of signal processing techniques to accurately detect mEP while mitigating the influence of stimulation artifacts and noise, then demonstrate a strategy for integrating multi-channel EMG responses into a single side effect biomarker (the mEP score). Next, we use data from a large patient cohort of intraoperative recordings (\n                    <jats:italic>N<\/jats:italic>\n                    = 54 subthalamic nucleus (STN) leads) to quantify several physiological features of mEP, including their response frequency, latency, amplitude, and waveform similarity properties.
