A relationship between bruxism and orofacial-dystonia? A trigeminal electrophysiological approach in a case report of pineal cavernoma

Table 1 Description of the neuromuscular responses of the jaw jerk response (JJr), the root-motor evoked potentials (R-MEPs) and the amplitude ratio

Parameters	Traces (Channel)	R-MEPs	JJr	Amplitude ratio JJr vs R-MEPs (%)
Onset Latency (ms)	1	1.92	7
Onset Latency (ms)	2	1.96	7.5
Amplitude (ms)	1	11	5.1	46
Amplitude (ms)	2	11.4	8.9	78

The evoked JJr and R-MEPs responses with the onset latency and peak-to-peak amplitude and the relationship in amplitude between the jaw jerk and the corresponding amplitude of the ipsilateral R-MEPs as amplitude ratio percentages. Ch1: right masseter. Ch2: left masseter.
