ZetrOZ's Ultrasonic Diathermy device is intended for use as a portable and wearable medical
device which, when applied to various areas of the body applies Low Intensity Therapeutic
Ultrasound (LITUS) to deep tissues. This device is FDA-cleared for pain reduction, treatment
of muscle spasm and joint contracture, and increasing local circulation. This study will
look at the use of therapeutic ultrasound to relieve pain and reduce disability in subjects
with chronic low back pain, a subset of which will have chronic low back pain due to a
herniated disc, over an 8-week treatment period.


Inclusion Criteria:

- Diagnosis of Chronic low back pain, may be secondary to herniated nucleus pulposus
(HNP) or other causes

- 18-60 years of age, inclusive

- Has Numeric Rating Scale (NRS) pain severity score of at least 4 for a minimum 5 days
over the 1 week Baseline Period prior to being randomized to treatment

- Pain lasting >3 months

- Has MRI from within 2 months prior to Screening (If no recent MRI is available, then
subject must agree to have MRI performed prior to randomization of treatment)

- If pain is secondary to HNP: MRI within the last 2 months demonstrating the presence
of a herniated disc; herniated disc is laterally located and not centrally located;
herniated disc is not sequestered

- Has the presence of radicular pain as assessed by a health care practitioner

- Is willing and able to self-administer treatment daily within their place of
residence or during normal daily activity, excluding bathing, showering, or other
water activities which may result in submersion of the study device.

- Is maintained on a stable pain management regimen, which may include opioid and/or
non-opioid analgesic medications, but must be willing to keep dosage(s) stable
through the study period; any dose adjustments that the investigator feels are
required during the study period must be discussed with the study sponsor; and the
use of any medications must be documented in the subject's Medication Log.

- Be willing to discontinue any other interventional treatment modalities on the lower
back during the study period (e.g., transcutaneous electrical nerve stimulation,
electronic muscle stimulation, traditional ultrasound).

Exclusion Criteria:

- Cannot successfully demonstrate the ability to put on and take off the device.

- Displays any condition which, in the judgment of the investigator, would make
participation in the study unacceptable including, but not limited to, the subject's
ability to understand and follow instructions.

- Participated in a clinical trial for an investigational drug and/or agent within 30
days prior to screening.

- Has arthritis, bone spurs, stenosis, fusions, or implants near the treatment area.

- Is pregnant.

- Is a prisoner.

- Is non-ambulatory (unable to walk).

- Has a pacemaker.

- Has a malignancy in the treatment area.

- Has an active infection, open sores, or wounds in the treatment area.

- Has impaired sensation in the treatment area, such as caused by chemotherapy or
anesthesia.

- Has a known neuropathy (disease of the brain or spinal nerves).

- Has a hereditary disposition (tendency) for excessive bleeding (hemorrhage).

- Has peripheral artery disease.

- Has BMI ≥30
