Pain Study #1

Journal:

Diabetes Care, Volume 27(1), January 2004

Study Site(s):

Joslin Center for Diabetes at Morton Plant Hospital

Number of Subjects:

27 (All Diabetic)

Study Design:

Prospective, Randomized, Double Blind, Placebo Controlled

Protocol Used:

All subjects in the study had chronic pain in the lower extremities. Subjects initially received treatment with active therapy pads on one limb and sham pads on the other limb 3 times per week for 40 minutes each vist for 2 weeks (6 treatments). This was followed by six active treatments of the same duration administered to both limbs duing the following 2 weeks.

Pain Endpoint:

Numeric Visual Analog Scale from 0 – 10 (10 being the worst pain)

Results :

Group	VAS Baseline	After 6 MIRE Treatments	After12 MIRE Treatments	P Value
1 (N=18)	4.2 + 2.3	3.2 + 1.9	2.3 + 1.7	<0.0001
2* (N=9)	4.2 + 3.9	2.6 + 2.3	2.0 + 2.3	NS
* Patients more impaired

Conclusion:

The results of the study demonstrate that treatments with near-infrared photo energy, MIRE™ delivered in the manner specified in the study protocol resulted in a significant reduction in lower extremity pain.

Conclusion:

Use of MIRE™ in combination with other physical therapy interventions is associated with reduced lower extremity pain.

Pain Study #4

Journal:

Age and Ageing, Volume 35(1), 2006

Study Site(s):

Multiple Sites

Number of Subjects:

252 (All Diabetic)

Study Design:

Retrospective Chart Review and Patient Questionnaire

Protocol Used:

All subjects in the study had chronic pain in the lower extremities. The initial therapy intervention included Anodyne® Therapy/MIRE™ for pain and circulation and physical therapy interventions such as therapeutic exercise, neuromuscular re-education and/or gait training. Patients then used an Anodyne Therapy System at home for an average of 8 months after the initial treatment in a clinical setting.

Pain Endpoint:

Numeric Visual Analog scale from 0 – 10 (10 being the worst pain)

Results :

Pain Reduction Based on Average Number of Months Using MIRE™

	1-3	3-6	6-9	9-12	12+
# of Patients	36	33	22	94	67
Ave. Months after MIRE Clinical Treatment	1.2	4.0	6.7	10.1	13.3
Mean Age	75	74	76	76	76
Male/Female	23/14	20/13	9/13	44/50	40/27
% of Patients Reporting Reduction in Pain	94%	80%	91%	85%	91%

Conclusion:

The medical records indicated that 220 out of 252 patients (87%, p< 0.0001) obtained substantial reduction in lower extremity pain. When patients have continuing access to MIRE™ in their homes following clinical treatment, there is a significant reduction in pain.

Pain Study #5

Journal):

Practical Pain Management, Volume 7(6), 2007

Study Site(s):

Multiple Sites

Number of Subjects:

493 (248 Diabetic; 245 Non-Diabetic)

Study Design:

Multiple Site Retrospective Chart Review based on Prospective, Repeated Measures Analysis in combination with patient phone survey on prescription pain medication use.

Protocol Used:

All subjects in the study had chronic pain in the lower extremities. The average treatment protocol was 3 x per week for 30 minutes for a mean of 15-19 treatments and included physical therapy interventions such as therapeutic exercise, neuromuscular re-education and/or gait training. After therapy was complete, 493 of 550 patients contacted agreed to provide answers to a health questionnaire.

Pain Endpoint:

Numeric Visual Analog scale from 0 – 10 (10 being the worst pain)

Results :

Mean pain reduction overall was 63.4%. 51.4% of patients who were on pain medications were able to reduce or eliminate their pain medications.

Pain response to MIRE™ is not based on the use of medication.

a = mean ± SD. b = P<0.0001 vs. initial pain. Meds = medications.
Changed Pain Meds indicates either a different dose or a different medication, or both.
Decreased Pain Meds indicates either a lowered dosage or a frequency or eliminated use of pain medications.

Conclusion:

MIRE, when administered as part of a physical therapy care plan prescribed by a physician, is associated with substantial lower extremity pain relief and the pain-relieving effects of Anodyne® Therapy/MIRE™ appear to be independent of pain medication use.
