Age group | 7 Years to 25 Years |
Eligibility | Inclusion Criteria: - Age 7-25 inclusive. - Presence of motor and/or vocal tics for at least 12 months. - Tics are of at least moderate clinical severity as evidenced by a Yale Global Tic Severity score of 14 or higher for motor or vocal tics only and 22 or higher for Tourette syndrome and present during the baseline assessment. - IQ estimate of 70 or higher - Comorbid disorder (e.g., ADHD, OCD, ODD) will be allowed provided that the tic symptoms are of primary concern to parents and comorbid symptoms are not of sufficient severity to require immediate treatment other than that provided by the current study. - Pre-existing stable medication (see protocol for details), tic or otherwise, will also be allowed provided the family agrees to refrain from med changes over the course of the acute phase of the study - Sufficient command of the English language to participate in informed consent and assessment procedures. - Agree for videotaping of study procedures - Clearance by treating dentist: Certification of good dental health provided by the subjects current dentist prior to enrollment in the study Exclusion Criteria: - Major psychiatric disorder at screening that would preclude full participation in study procedures including psychosis, mania, depression, untreated combined type ADHD, autism and pervasive developmental disorders. - Medication changes are planned during the acute and follow-up phase of treatment. - Other dental health problems that might interfere with the assessment, installation, or wearing of orthotic device. - Does not consent to being videotaped |

Primary | Change in Global Severity of Tics and Clinical Condition as Measured by YGTSS | The primary clinical outcome measures included the Yale Global Tic Severity Scale (YGTSS). The YGTSS is a semi structured interview designed to elicit information regarding the character & anatomical distribution of tics observed during the course of 1 week interval, prior to clinical assessment. Following completion of the interview & construction of a "tic inventory", clinicians rate severity of motor and photic tics along with 5 separate dimensions (frequency, intensity, number, complexity, interference).
The YGTSS is comprised of a list of motor and vocal tics & the participant endorses which tics are currently present. Motor and vocal tics are then separately rated for Number, Frequency, Intensity, Complexity, Interference & Impairment, each on a 6 point likert scale ranging from 0 (none) to 5 (Severe).This results in a range of 0-25 for motor tics & 0-25 for vocal tics, for a total score range of 0-50. A score of 0 indicating a lack of tics & 50 represent the most severe tics. |

Secondary | Change in Number, Frequency, and Intensity of Motor and Vocal Tics as Measured by the Clinical Global Impressions Scale - Severity | To assess global severity of tics and change in the clinical condition over time, the Clinical Global Impressions Scale - Severity (CGI-S) was utilized. The Severity of Illness has a low score of 0 and high score is 7. The low score of 0 represents that the subject was not assessed and the high score of 7 represents among the most extremely ill subjects. | Baseline Visit, Week 2 Visit |
