Phoenix Thera-Lase for Treating Chronic Pain in Patients Taking Opioid on a PRN Basis


Brief description of study

Hypothesis: Use of high level vs low level cold laser treatments will reduce chronic pain and the need for PRN opioid-containing analgesic medications.

Secondary Hypothesis: High level (vs low level) laser treatments will increase the patients level of physical activity and quality of sleep.

Detailed Study Description

Previous studies with low level laser therapy have reported beneficial effects on the level of pain in patients with a variety of chronic pain conditions.

We designed this controlled, double blind, randomized study to determine in the active laser group would have a reduction in the need for 'PRN pain medication'.

Screening Testing

  1. Urine-toxicology screen.
  2. Assessment of level of activity and range of motion and functional capacity evaluation for upper and/ or lower extremity.
  3. Current drug history and use of analgesic medications including both opioid and or non-opioid analgesic medications.
  4. Drug history and current medications along with non-traditional alternative treatments such as (e.g. acupuncture, massage, herbal treatments, etc.)

Protocol Outline After obtaining written informed consent, patients will be asked to complete all the pre-screening and "entry" questionnaires (e.g., SF-36).

11- point Verbal Rating Scale (VRS) for pain at rest and with physical activity (0= none to 10= severe), level of physical activity (0=inactive to 10= fully active), and quality of sleep (0=poor to 10=excellent).

Current analgesic [pain] medications both daily and PRN medications. Randomized into active (Phoenix Thera-Lase [ PTL]) or "Low level" PTL group using a computer generated random numbers table.

Treatment Sessions After obtaining written informed consent for participating in the study and signing the standard HIPPA forms, the patient will be asked to describe the location of their current pain symptoms.

Pre-treatment baseline assessments VRS for pain at rest and with physical activity (e.g. walking, climbing stairs) Kinesiology functional capacity evaluation (FCE) for upper and/ or lower extremities or low back (depending on location of pain).

Current opioid and non-opioid analgesic medication usage Clinical opioid withdrawal scale (COWS) at baseline (the COWS will be repeated at the end of the 1st, 2nd, and 3rd week of treatments).

Treatment sessions - Active or low level therapy for 20 - 40 min on Monday, Wednesday, and Friday for 3 weeks.

Post- treatment sessions VRS for pain at rest and with ambulation immediately after each treatment

After the end of 3-week treatment period Repeat pre-screening questionnaires. Kinesiology functional capacity evaluation (FCE) for upper and/ or lower extremities or low back (depending on location of pain).

Long-term Follow Up 30-days after the last treatment session, a standardized follow-up questionnaire will be administered.
