Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

160 patients with moderate to severe acute or exacerbations of chronic low back pain presenting for chiropractic and rehabilitation care will be randomized to one of two conditions: a pain relief belt device incorporating multiple speeds of vibration and optional heat, cold, and pressure delivered through a sculpted metal plate; or an 8 channel prescription TENS unit. Patients will be prompted by a Qualtrics text link to a secure data recording site collecting pain and medication use.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Self-report NRS measures >=4 (moderate to severe)
  • Capacity to understand all relevant risks and potential benefits of the study (informed consent)
  • Willingness to communicate information on prescription pill # and dose, or dose and pill type if medication is prescribed by someone else.

Exclusion Criteria:

  • Pacemaker
  • Radicular pain likely reflecting a surgical or mechanical problem

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: DuoTherm VibraCool Back Device
A multimodal low back pain relief device incorporating 8 mechanical stimulation patterns of vibration and 5 intensity settings with optional heat, cold, or pressure delivered through a sculpted metal plate attached by a belt and controlled by buttons on the belt. Patients will be instructed to use the device daily for 30 minutes.
Device: Duotherm VibraCool Back Device
Active New multimodal pain device
Other Names:
  • Buzzy
  • Vibracool plus heat or pressure
Active Comparator: Multimodal TENS Unit
LG SMART TENS stimulator is an 8-channel portable electrotherapy device featuring transcutaneous electrical nerve stimulation (TENS) therapeutic device, which is used for pain relief. The stimulator sends a gentle electrical current to underlying nerves and muscle groups via electrodes applied on the skin. The parameters of the device are controlled by buttons on a controller with an adjustable intensity level.
Device: TENS 8-channel unit

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in current pain intensity from initial to final
Time Frame: Daily for 30 days, then weekly and monthly until 3 months (acute) or 6 months (chronic)
Self-rated current pain on Numeric Rating Scale with 0 no pain and 10 maximum pain
Daily for 30 days, then weekly and monthly until 3 months (acute) or 6 months (chronic)
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference
Time Frame: Baseline then weekly and monthly until 3 months (acute) or 6 months (chronic)
Response formats for all scales are a 5-point ordinal rating scale of "Not at all," "A little bit," "Somewhat," "Quite a bit," and "Very much," where lower scores are better and higher scores indicate worse pain. The outcomes being addressed are Change in Monthly Pain Interference (8 questions, yielding possible scores of 8 (low) to 40 (highest) normed on a T-Score where 50 is the average in the United States, 40.7 is "no disability", 55 is mild, 57.7 is moderate, and 65.7 is severe
Baseline then weekly and monthly until 3 months (acute) or 6 months (chronic)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Resolution of disability using PROMIS Pain Interference
Time Frame: Baseline then weekly and monthly until 3 months (acute) or 6 months (chronic)
Achievement of average pain interference of a T-Score of 50 at last recorded PROMIS Pain Interference
Baseline then weekly and monthly until 3 months (acute) or 6 months (chronic)
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (8a) measures in those with intractable pain as defined and compared with surgical multifidus intervention studies
Time Frame: Initial through 6 month measurements (or 13 week if chronic enrolled as acute)
Comparison between the experimental and active control interventions crosswalked with the Oswestry Disability outcomes in multifudus electrical stimulation studies.
Initial through 6 month measurements (or 13 week if chronic enrolled as acute)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duotherm use
Time Frame: 6 months
