Diffusely increased insertional activity: "EMG disease" or asymptomatic myotonia congenita? A report of 2 cases. The term "EMG disease" is used by some to describe the unexpected finding of diffusely increased insertional activity on needle electromyography in an otherwise asymptomatic person. The ...

Objective: N/ABackground: "EMG disease" is characterized by diffusely increased insertional activity on needle electromyography (EMG) without the presence of any neuromuscular diseases. Familial aggregation in many cases suggests an underlying muscular channelopathy of genetic origin such as via the CLC...

4) Needle electromyography (EMG) was performed on the left and right arm. All muscles tested showed increased insertional activity, 1+ to 2+ fibs/sharps, and myotonic potentials. The corresponding paraspinal muscles showed increased insertional activity and myotonic potentials. Discussion Published ...
