T-Scan and EMG gadgets and then asked to bite into the sensor after inserting it into the mouth. The patient is asked to bite hard into the sensor and open, for three times for a multibite, to bite hard and hold for few seconds, and then to glide to left or right to obtain the records as shown in Figures 1-3. The assessment determined that patient had no internal derangements of significance but presented with prolonged OT of 1.32 s when closing into MIP, prolonged left excursive disclusion time of 1.15 s, and prolonged right excursive disclusion time of 0.86 s [Figures 1-3].

OT <0.2 s; DT <0.4 s). Of note is that the time to muscle shut down of the working temporalis muscles in Figures 2 and 3 ranges between 4.0 and 5.2 s, which is far too long to be physiologic. The patient was explained that her disclusion times were too long, causing excursive muscle hyperactivity detected in the EMG data [Figures 2 and 3 to the right of line C], which caused her muscular symptoms.

On post-ICAGD, the corrected OT was 0.17 s [Figure 4], the left excursive DT was 0.16 s [Figure 5], and the right excursive DT was 0.22 s [Figure 6].
Post Treatment Left Lateral- time to muscle shut down after C shorter from ICAGD

On post-ICAGD, the corrected OT was 0.17 s [Figure 4], the left excursive DT was 0.16 s [Figure 5], and the right excursive DT was 0.22 s [Figure 6]. ICAGD [Figures 5 and 6 to the right of line C]. In addition, the time to muscle shut down of both working temporalis was drastically shortened from the ICAGD corrections.
