Objective We developed a hybrid recording system for EMG and ultrasound (US) to allow simultaneously display on one screen.

Background US combination with EMG simultaneously is expected to be more useful by supplementation each other's disadvantages. However, since both devices are too large, and screens are separate, the examiner can only perform either examination on the same time. Here, we tried to fusion both outputted screen images.

Design/Methods The video signals are taken out from the external video output terminals of both devices and mixing with video switcher, then split displayed images on the other screen are captured as a movie to save to the storage for offline analysis. All equipment is commercially available for general consumer use and inexpensive.

Results EMG monitor and US image were visualized by split display method on the wide screen simultaneously without delay time. The device enabled precise needle insertion in concentric EMG examination at the diaphragm and paraspinal muscles. Furthermore, we could know some facts about meaningful matters, for example, where and how do muscle fibers twitch in fasciculation, does fibrillation potential involve muscle contraction visible by US.

Conclusions This device gives us some novelty worth in neuromuscular electrodiagnostic field. Each EMG findings may have to be re-evaluated by visual behavior.
