- Brief Summary
Background: An innovative, non-invasive, and reversible Intra Auricular Device (IAD) has recently been introduced to treat temporomandibular muscle and joint disorders.Aim: To evaluate the effects of the IAD on pain, psychosocial domain and Pressure Pain Threshold (PPT) of masticatory muscles in patients with TMD pain. Methods: Ten subjects with TMD pain and with pain intensity higher than 30 mm on a VAS scale were included in the study. Patients received the IAD and counselling. Assessments included questionnaires of the DC/TMD Axis II questionnaires (Characteristic Pain Index, Interference, Jaw Functional Limitation Scale, Patient Health Questionnaire 9, Patient Health Questionnaire 15, Generalized Anxiety Disorder scale, Oral Behavior Checklist and Oral Health Impact Profile-22, Axis I clinical examination and PPTs at baseline (T0), after one month (T1), three months (T2) and six months (T3) from the first use of the device. PPTs were measured at anterior temporalis muscles, masseter muscles and right thenar as a control site.The Shapiro-Wilk test was used for the normal distribution of data. The difference among the longitudinal timepoints for variable was analysed with ANOVA. Statistical significance was accepted at p \< 0.05.
- Detailed Description
The goal of ths study is to evaluate the effects of a new intra auricular device, the IAD, on pain, psychosocial domain and Pressure Pain Threshold (PPT) of facial muscles in patients with diagnosis of TMD pain according to the Diagnostic Criteria of Temporomandibular Disorders

Group Intervention Description TMD Pain group Intra auricular device (IAD) Arm included patients with TMD Pain intensity \>3 on a VAS scale and with diagnosis of myofascial pain, either alone or in combination with arthralgia, headache attributable to TMD or with disc displacement with reduction. Participants had to be 18 years of age or older. All subjects had to wear the device for 6 months and it should not be used for more than 23 hours in a 24-hour period
- Primary Outcome Measures
Name Time Method Change of Pain evaluated with instrumental exam( Pain Pressure Threshold) Six months from the first use of the device Pain Pressure Threshold were assessed by a single examiner at the anterior temporalis and masseter muscles (respectively TdxM; TsxM; MdxM; MsxM). An additional measurement was performed at the right thenar muscle (TenM) selected as a control muscular site.
Change of Pain (evaluated with Characteristic pain intensity scale) Six months from the first use of the device This questionnaire is a valid instrument assessing pain intensity, numbers of days with interference and pain-related disability in the last month. The characteristic pain intensity score, which ranges from 0-100, is calculated as the mean intensity ratings for reported current, worst, and average pain
Psychosocial domain positive change Six months from the first use of the device Evaluation of psychosocial positive change through psychosocial questionnaires.
