Evolution of the activity of the masticatory muscles before and after temporomandibular joint replacement: a clinical and functional study.

On average, the MVC of the T muscles was higher than for the M (MVC Right T = 277 ± 38 µV, MVC Left T = 285 ± 113 µV, MVC Right M = 212 ± 97 µV, MVC Left M = 231 ± 86 µV). Clinical outcomes and QoL for the patients Before the surgery, the pain was extreme for the two patients, rated as a "not controlled pain". Evolution of the EMG activities for the patients Before the surgery, the EMG activities during the rest were higher than the asymptomatic values for all the muscles. [Extracted from the article]
