Sana Health, Inc., is developing a non-narcotic, non-addictive, wearable device to determine if it is effective in reducing symptoms of posttraumatic stress disorder (PTSD).

The Sana Device is an externally worn mask that physically contacts the skin of the face. It delivers Audio Visual Stimulation (AVS) in the form of coordinated pulses of light (through closed eyelids) and sound (through earphones) at targeted frequencies. It is meant to be worn at least twice per day at home.

Participants will be in one of two groups, randomly assigned like a flip of a coin. One group will receive VA Medical Center (VAMC) treatment as usual or treatment as usual plus use of the Sana device.

Participants will complete 3 virtual visits for assessments and four virtual check in visits.

This study is open to Veterans and military service members with a VA medical record seeking treatment for PTSD.

People who experience a stroke often have problems performing many different tasks during daily life. Most studies investigating stroke recovery and rehabilitation focus only on one type of task. The purpose of this research study is to measure individuals' function in many areas that can be affected by a stroke, such as their balance, mood, memory, reaching, and speech. This study will also track changes that can occur with task performance over time.
