  Purpose

The intent of this project is to execute a high-quality double-blinded randomized controlled clinical trial that compares the H-Wave® device with a commonly used TENS device with a sub-therapeutic electrocurrent device. This study will provide a definable level of evidence for treatment efficacy, and provide a basis for evidence-based recommendation for or against utilization for these two modalities. The results for H-Wave® device, if positive, could significantly impact morbidity by providing a non-invasive, non-pharmacologic treatment for symptomatic relief, and reduce overall disability and health care costs associated with chronic low back pain.

Arms Assigned Interventions
Active Comparator: H-Wave Device
H-Wave Device with Usual Care
Device: H-Wave
Proprietary electrotherapy device using electrical stimulation of unique wave form and energy level that is delivered through transcutaneous electrodes to nerves and soft tissue for analgesic effect.
Other Name: H-Wave is the proprietary name of the device. There is only one model currently.
Active Comparator: TENS
Transcutaneous electrical nerve stimulation (TENS) Device with Usual Care
Device: Transcutaneous Electrical Nerve Stimulation (TENS)
Electrotherapy device that delivers current at different frequency, amplitude, and wave form through cutaneous electrodes placed near body parts with pain for temporary analgesic effect. The study device is installed inside the same housing as the H-Wave Device and Sham Device, so that all appear the same. There are no identifying marks on the case that participants will recognize in order to maintain blinding.
Other Name: Chattanooga Intellect TENS Device
Sham Comparator: Sham Electrotherapy
Sham Device plus Usual Care.
Device: Sham
The sham device is a TENS unit modified to have minimal electrical output. The device is installed in the same housing as the two active arms with equal weight, so that each device in the study appears identical.

Detailed Description:

H-Wave® Device Stimulation (Intervention A) plus usual care, transcutaneous electrical nerve stimulation (TENS) (Intervention B) plus usual care, and sham electrotherapy plus usual care (control). Each treatment arm will have identical participants enrolled (n=38 per arm) of with the same number of visits and investigator contact time.

Eligible participants will be allocated through computerized randomization utilizing a stratified permuted-block randomization employing random block sizes. Allocation is concealed. Participants and assessors will be blinded. Participants will not be told what types of electrotherapy devices are being studied, only that there are different types, and that they may be randomized to receive a sham device.

Patients will be instructed on the use of the device they received to perform daily home therapy. Subjects will be assessed at week 1, 4, 8 and 12 for the primary and secondary outcomes measures. Compliance to treatment will be measured through an electronic meter on each of the devices, as well as by patient diary. Patients will be allowed to receive usual care from their own health care provider, with the exception of invasive procedures or surgery. Results will be analyzed by intention to treat methods.
