Surface EMG is a non-medical procedure used to assess muscle activation by several professionals, including physiotherapists, kinesiologists and biomedical engineers. Needle EMG is an electrodiagnostic medicine technique commonly used by neurologists. The signals can be analyzed to detect abnormalities, activation level, or recruitment order, or to analyze the biomechanics of human or animal movement. An electromyograph detects the electric potential generated by muscle cells when these cells are electrically or neurologically activated. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram. Electromyography ( EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles.
