Trial Outcomes & Findings for Treatment Outcomes for Temporomandibular Disorders (TMD) Via the Clayton Intra-aural Device (CID) Clinical Trial (NCT NCT00815776)

NCT ID: NCT00815776

Last Updated: 2010-08-24

Results Overview

The Craniomandibular Index (CMI) is designed to provide a basis for evaluating the severity of Temporomandibular Disorder (TMD) signs and symptoms. The assessment involves asking questions related to the condition of Mandibular Movement, TMJ noise, and palpations of the extraoral muscle, neck muscle, TMJ capsule and intraoral muscle. The answers to all of the questions are combined to calculate a score from 0 to 1 in which 0 represents no TMD signs and symptoms and 1 represents the most severe TMD signs and symptoms.

Participant Flow

Subjects completed a screening visit and were provided a diary record their Temporomandibular Disorder severity. Subjects returned to the clinic, were randomized if they qualified, and were assigned a treatment group. 150 subjects were planned, but the site over-enrolled 2 subjects due to a temporary problem with the database subject count.

PRIMARY outcome

Timeframe: Change from Baseline in Craniomandibular Index (CMI) Scores at 3 months (in a scale)

Population: The arm that includes "0" (Jaw Exercise) is reported in Seconary Outcome Measure Table.

The Craniomandibular Index (CMI) is designed to provide a basis for evaluating the severity of Temporomandibular Disorder (TMD) signs and symptoms. The assessment involves asking questions related to the condition of Mandibular Movement, TMJ noise, and palpations of the extraoral muscle, neck muscle, TMJ capsule and intraoral muscle. The answers to all of the questions are combined to calculate a score from 0 to 1 in which 0 represents no TMD signs and symptoms and 1 represents the most severe TMD signs and symptoms.

PRIMARY outcome

Timeframe: From Baseline through 3 months post-baseline visit.

Subjects were assessed for adverse events from the baseline visit through study completion (3 months post-baseline). Adverse events were categorized by the investigator for severity and relationship to treatment.
