Detailed Description

Chronic neuropathic pain (NP) is an extremely debilitating condition with few treatment options and many of which with multiple side effects. This will be a randomized, sham-controlled trial that will investigate the effectiveness of a novel wearable device called the Sana Pain Reliever (Sana PR) at reducing chronic neuropathic pain. The Sana PR is a device comprised of a Mask to be worn over the eyes with a pair of ear buds to be worn in ears. It displays light and sounds in a predetermined algorithm which runs for 16 minutes at a time. The underlying mechanism of action for the Sana PR is Audio Visual Stimulation (AVS), a form of non-pharmacological intervention that induces a brain wave response called Frequency Following Response (FFR), which has been used for both performance enhancement and symptom management. The device will be used with a compatible tablet application that will collect data from each session that the device is used. This data will be collected through user inputs of responses to several questionnaires. This will be an at-home trial and participants will be loaned the Sana Pain Reliever device and a tablet device to run the application for the duration of the study. The trial will last a total of 14 weeks and will involve four study visits, either in-person at the Abilities Research Center at Mount Sinai Hospital in New York City, or remotely using a video call. The trial includes two baseline sessions on weeks 0 and 2, 8 weeks of the at-home intervention, and post-intervention sessions at the end of weeks 10 and 14. Participants will be instructed to use the device at the end of the day prior to going to sleep as well as whenever they experience greater than typical pain during the day . Data during the at home portion of the trial will be recorded daily via the application. The application will also prompt participants to answer fortnightly weekly questionnaires and send out compliance reminders. Additionally, a series of pain, sleep and quality of life assessments will be completed by participants at both baseline visits, a post-intervention visit and a 4-week follow-up visit.

It differentiates "poor" from "good" sleep quality by measuring seven areas (components): subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction over the last month. Full score from 0-21, with higher score indicating worse sleep quality. Change in score at Week 2, Week 10 and Week 14 as compared to Baseline.

It will evaluate pain from no change (score 0-1), minimally improved (score 2-3), much improved (score 4-5), and very much improved (score 6-7). The patients will answer the following question: "Since beginning treatment at this program, how would you describe the change (if any) in activity limitations, symptoms, emotions, and overall quality of life related to your condition?". Full score from 0-7, with higher score indicating more improvement. Change in score at Week 14 as compared to Week 10.

Time Frame: Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
The Questionnaire Type 9 for Depression (PHQ-9) is a self-administered version of the PRIME-MD diagnostic instrument for common mental disorders. The PHQ-9 is the depression module, which scores each of the nine DSM-IV criteria as "0" (not at all) to "3" (nearly every day). It has been validated for use in primary care and is used to monitor the severity of depression and response to treatment. Full scale from 0-27, with higher score indicating more severe symptoms. Change in score at Week 2, Week 10 and Week 14 as compared to Baseline.
Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
Change in General Anxiety Disorder 7-item Questionnaire (GAD-7)
Time Frame: Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
The General Anxiety Disorder 7-item questionnaire (GAD-7) is a 7-item questionnaire that asks user to rank how often they have been bothered by seven problems over the past two weeks from "0" (not at all) to "3" (nearly every day). The items that users are asked to rank levels of nervousness, anxiousness, relaxing, restlessness, irritability and fearfulness. Full scale from 0-21, with higher score indicating more symptoms. Change in score at Week 2, Week 10 and Week 14 as compared to Baseline.
Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)

Time Frame: Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
The WHOQOL-pain scale is for a specific focus on the impact of pain on QOL. The WHOQOL-pain has 22 items on the pain and discomfort module (PDM) and the importance of items within a user's daily life. The Pain facet has 4 items (1-5) which are averaged to produce the WHOQOL-Pain Pain Facet. Full scale from 1-5 with higher score indicating higher quality of life. Change in score at Week 2, Week 10 and Week 14 as compared to Baseline.
Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
Change in World Health Organization Quality of Life Bref (WHOQOL-BREF)
Time Frame: Baseline 1(Week0); Baseline 2 (Week 2); Post-assessment (Week 10); Follow up (Week 14)
The WHOQOL-BREF is a used to produce a quality of life profile for an individual that is derived from four domains. There are 26 questions which ask users to respond to quality of life (QOL) questions on a scale of 1-5 (1-Not at All, Very Poor, or Very Dissatisfied; 5- Completely, Very Good, or Very Satisfied). The QOL domain assess quality of life and has a score from 1-100. Full scale from 0-100 with higher score indicating higher quality of life. Change in score at Week 2, Week 10 and Week 14 as compared to Baseline.

Visual Analogue Scale (VAS)-Pain
Time Frame: before and after each time device used up to 14 weeks
Visual Analog Scale (VAS) to measure pain: a measure of "no pain" to "Worst pain imaginable" along a line. Participants will be asked to mark the level of their pain along the line. Full scale from 0-100 with higher score indicating more pain.
before and after each time device used up to 14 weeks
Visual Analogue Scale (VAS)-Sleep
Time Frame: first 3 days and 14 weeks
Visual Analog Scale (VAS) to measure sleep: a measure of "did not sleep at all" to "best possible night's sleep" along a line. Participants will be asked to mark the level of their sleep along the line. The Sana Health application will prompt users to answer this scale before they use the device for the first time each day. A linear mixed model used the daily sleep-vas scores to estimate the percent of change for both arms over the course of the study (Baseline to Week-14). Percent change from mean of first 3 days. 1% to 100% with higher score indicating improved sleep quality.
