Overview

This trial is active, not recruiting.

Condition chronic low back pain
Treatments biomodulator, usual care (medication + exercise)
Sponsor Brooke Army Medical Center
Start date January 2013
End date July 2016
Trial size 75 participants
Trial identifier NCT02707094, TSNRP-N12-006

Summary

The purpose of this study is to determine the efficacy of self treatment with the Biomodulator device to decrease chronic low back pain (LBP) in active duty service members. In addition, the study will track the use of pain medication and the impact of pain on symptoms of anxiety, depression and Post Traumatic Stress Syndrome (PTSD).

Usual Care: Participants will receive guidance on over-the-counter and prescribed pain medications to use to treat their chronic low back pain symptoms. The Research Coordinator (RC) will provide instructions for low back pain stretching and strengthening exercises. The Licensed Provider (LP) will determine if any exercises should be excluded based on their physical limitations. Participants enrolled in the usual care treatment arm will track the frequency of their back stretching and strengthening exercise sessions on the Pain Medication & Exercise Diary. For the purpose of this study, treatment compliance will be met if participants complete the exercises a minimum of three times per week.
usual care (medication + exercise)
The study LP will prescribe an analgesic medication regimen based on the participant's needs. These medications may consist of Non-steroidal anti-inflammatory Drugs (NSAIDs) (ibuprofen, naproxen sodium, etc.), muscle relaxants (Flexeril, Robaxin, valium, etc.), non-narcotic analgesic medications (acetaminophen, aspirin, tramadol, etc.), or narcotic medications (Tylenol #3, Percocet, Vicodin, etc.) depending on the severity of their pain and co-morbid conditions. The RC will also provide instructions for LBP stretching and strengthening exercises. The following exercises will be recommended as a daily regimen: the partial curl, cat and camel, pelvic tilt, quadriceps, arm/leg raises,trunk rotation, single knee to chest stretch, standing hamstring stretch, and double knee to chest stretch.
(Experimental)
Biomodulator + Usual Care treatment group: Usual care, as described above, will be provided to all participants randomly allocated to this treatment group, in addition to treatment with the Biomodulator three times per week x 4 weeks. The licensed provider will review medication and treatment logs, prescribe pain medications as indicated, and assess for treatment side effects. In addition to treatment with the Biomodulator, the participant will perform back stretching and core strengthening exercises for a minimum of three times per week as instructed and will be told to use their prescribed pain medications as needed to self-treat their low back pain symptoms (as previously described above).
biomodulator Tennant Biomodulator
The Biomodulator is a type of very low frequency TENS known as pulsed electromagnetic field therapy (PEMF). Unlike TENS devices that deliver 1-80 milliamperes of electrical current, PEMF devices deliver short bursts of electrical microamperes (millionths of an ampere) to injured tissues without producing heat or interfering with nerve or muscle function. Micro-current levels between 20-500 microampere appear to be most effective at relieving pain and inflammation and promoting tissue healing by realigning the natural electrical balance that exists within the cells that has become disrupted due to injury.
usual care (medication + exercise)
The study LP will prescribe an analgesic medication regimen based on the participant's needs. These medications may consist of Non-steroidal anti-inflammatory Drugs (NSAIDs) (ibuprofen, naproxen sodium, etc.), muscle relaxants (Flexeril, Robaxin, valium, etc.), non-narcotic analgesic medications (acetaminophen, aspirin, tramadol, etc.), or narcotic medications (Tylenol #3, Percocet, Vicodin, etc.) depending on the severity of their pain and co-morbid conditions. The RC will also provide instructions for LBP stretching and strengthening exercises. The following exercises will be recommended as a daily regimen: the partial curl, cat and camel, pelvic tilt, quadriceps, arm/leg raises,trunk rotation, single knee to chest stretch, standing hamstring stretch, and double knee to chest stretch.

Eligibility Criteria

Male or female participants from 18 years up to 62 years old.

Inclusion Criteria: - active duty Service Members (SMs) between the ages of 18 and 62, inclusive - history of chronic LBP (i.e. intermittent or continuous LBP symptoms present for 3 months or greater prior to entry into the study - participants must be using narcotic and/or non-narcotic oral analgesic medications to treat their chronic LBP symptoms on a weekly basis - must be able to speak and read English and understand the study procedures Exclusion Criteria: - pacemaker or implanted electronic device - history of stroke, blood clots, or cardiac arrhythmias - pregnancy - no self-reported history of prescription medication abuse or sole-provider contract for prescribed narcotic medications - open wound over site of chronic pain; - history of spinal surgery - participation in a clinical trial for an investigational drug/ treatment within last 30 days - undergone treatment with TENS, biofeedback, or acupuncture within last 30 days - prior treatment with the Biomodulator - LBP "red flags": fever, trauma, progressive motor or sensory deficit, saddle anesthesia - participation in the study would delay the medical board (MEB) processing of the service member off of active duty status or would delay a return to duty status to their home unit
