Conditions
Brief summary
Trial title: A Randomized, Double Blind Sham Controlled Clinical Trial to Evaluate the Efficacy of Electrical Vestibular Nerve Stimulation (VeNS), Compared to a Sham Control for Treatment of PTSD The aim of this study: To better evaluate the efficacy of non-invasive electrical vestibular nerve stimulation (VeNS) as a method of treating PTSD, as compared to a sham control. Allocation: Randomized to either active device or control device usage. Endpoint classification: Efficacy Study Intervention Model: Parallel Assignment in 1:1 active to control allocation Sample size: The aim is to recruit a total of up to 400 participants. The study will last 12 weeks in total for each subject.

Inclusion criteria
* Signed informed consent * Diagnosed PTSD by a medical practitioner * Post-Traumatic Checklist (PCL-5) score or 31 or above * Eligibility confirmed via the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) * Male or female, age ≥ 22 years and ≤ 80 years at the time of signing informed consent * Ability and willingness to complete all study visits and procedures, including completion of mental health questionnaires * Ability and willingness to adhere to 30 minutes usage of the device daily for the duration of the trial * Agreement not to start any new PTSD, mental health, or insomnia medications for the duration of the trial and/or to inform the study team if intending on starting any new PTSD, mental health, or insomnia medications * Agreement not to change any PTSD specific treatments for the duration of the trial e.g cognitive processing therapy * Agreement not to undergo any significant lifestyle changes that may affect sleep (e.g. excessive exercise, sleep interventions etc.) for the duration of the trial * Agreement not to use sleep trackers (e.g. Fitbit) for the duration of the trial * Agreement not to travel across different time zones for the duration of the trial * Access to Wi-Fi (for app to be able to upload usage data) * Access to computer, laptop, iPad or tablet (to conduct remote study visits and complete study questionnaires remotely) * Screening review by PTSD physician (study PI) * Willingness to download and use a video platform (e.g Zoom) to conduct remote study visits * Willingness to engage weekly with your Clinical Trial Mentor (CTM)
Exclusion criteria
* History of skin breakdown, eczema, or other dermatological condition (e.g., psoriasis) affecting the skin behind the ears * History of severe tinnitus or vertigo * History or presence of malignancy within the last year * Use of beta-blockers within 1 month of starting the study * History of chronic viral infection that causes vestibular neuropathy (e.g., hepatitis or HIV) * Use of antihistamines * A history of stroke or severe head injury as defined by a head injury that required a craniotomy or endotracheal intubation (in case this damaged the neurological pathways involved in vestibular stimulation) * Taking H2-receptor antagonist medication * Presence of permanently implanted battery powered medical device or stimulator (e.g., pacemaker, implanted defibrillator, deep brain stimulator, vagal nerve stimulator etc.) * Female who is pregnant, breast-feeding or intends to become pregnant or is of childbearing potential and not using an adequate contraceptive method * Diagnosis of epilepsy * Diagnosis of active migraines * Previous use of Modius device * Participation in other research studies sponsored by Neurovalens * Participation in any other PTSD studies * Not fluent in English language * Have a member of the same household who is currently participating in this study * Failure to agree to use of device daily during study participation * Any other medical condition, or medication use, that in the opinion of the PI is likely to make the subject refractory to VeNS.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Posttraumatic Stress Disorder Checklist PCL-5 score | 12 weeks | To evaluate the effect of the Modius Sleep device, relative to control group, on the symptoms of PTSD, quantified by change in the PCL-5 Score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 36-Item Short Form Survey (SF-36) score | 12 weeks | To evaluate the effect of the Modius Spero device, relative to control group, on quality of life quantified by change in SF-36 score. |
| Generalised Anxiety Disorder (GAD-7) score | 12 weeks | To evaluate the effect of the Modius Spero device, relative to control group, on anxiety, quantified by change in the GAD-7 score. GAD-7 is a self-report rating scale assessing the severity of anxiety (range 0-21), with higher score indicating more severe anxiety. |
| Insomnia Severity Index (ISI) score | 12 weeks | To evaluate the effect of the Modius Spero device, relative to control group, on participants with insomnia. ISI is a self-report rating scale assessing the severity of insomnia symptoms (range 0-28) with higher scores indicating a more severe insomnia. |
