Brief summary
Ten patients with acute or chronic low back pain will be invited to try a multimodal device for 20 minutes. Pain will be recorded prior to and after use, and feedback on the device will be elicited.
Detailed description
To facilitate data collection of a short-term intervention, the investigators chose to enroll patients from a mixed physical therapy/chiropractic practice with demographic and economic diversity in the metro Washington area. The neuromodulatory device will have patient controlled frequencies at 50Hz, 100Hz, and 180Hz attached to a 12 x 22 cm metal plate ergonomically curved to fit the low back. The device will be wearable with a neoprene belt on both sides for patients to adjust pressure. The metal pocket in our device holds a 221g clay pack capable of being frozen to 15F or heated to 110F or patient tolerance, with 30 minute thermal capacity. A convenience sample of 10 patients at the clinic was invited to give feedback on the prototype device after informed consent. Changes suggested were incorporated and after informed consent a second group of ten gave will give feedback with the production-ready device.
Interventions
Low back plate belt with mechanicothermal and pressure intervention options.

Intervention model description
Consecutive low back pain patients were offered to try a new device and give feedback on a prototype. Once the feedback was obtained, the changes were incorporated into a production-ready model and re-evaluated.
Eligibility
Inclusion criteria
* Acute or chronic low back pain as chief complaint * Capacity to understand all relevant risks and potential benefits of the study (informed consent); * Willingness to communicate information
Exclusion criteria
* Radicular pain likely reflecting a surgical or mechanical problem * BMI greater than 30 (device won't fit) * Sensitivity to cold or vibration (e.g Raynaud's or Sickle Cell Disease) * Diabetic neuropathy rendering a patient unable to determine if the device is too hot * New neurologic deficits * Skin lesions over the low back area * Contraindication to any medication for pain management that would impact analgesic use record * Inability to apply DuoTherm

| DuoTherm VibraCool Back Device Patients will be offered a pain relief belt device incorporating multiple speeds of vibration and optional heat, cold, and pressure delivered through a sculpted metal plate. They will be able to choose from 8 patterns of vibration with the multiple motors (50, 100, 200Hz), and hot or cold, and will wear the device for 20 minutes.
