Alternative to tongue EMG in ALS

Sonoo et al. studied 100 ALS patients. Tongue EMG is sensitive when patients can relax for examination, but only about half or less can. Fibs , positive waves and fasciuclations were seen in 62 % of trapezii, 17 % of sternocleidomastoid muscles, and 8 % of tongue, whereas the number was zero abnormal muscles in cervical spondyslosis patients.
