Abstract: | Needle electromyography (EMG) is an established method of evaluating motor unit and muscle fibre function and pathology in clinical practice, while the development of advanced techniques including single-fibre EMG and combined recordings with other modalities have become increasingly useful in research. The development of quantitative EMG in particular had led to greater reproducibility and inter-rater reliability. This review provides an overview of standard needle EMG as well as discussing advanced recording and analysis techniques and their increasing role in clinical research. |
