Clinical Proof

Clinical research has demonstrated that TENS and lumbar support are an effective method of pain relief. For a more in-depth insight into the clinical trials please click on the relevant trial.

Participants: 2003 chronic pain patients took part in the study.

Methods: 376 patients were randomly selected after 6 months of treatment.

Results:There was a significant reduction in pain medication and associated costs due to TENS effectively treating their pain.

Objective: A study was conducted to assess a variety of treatment outcomes in long-term users of transcutaneous electrical nerve stimulation (TENS) who suffer from chronic pain. Key components of the study examined the effects of long-term TENS therapy on pain-related medications and physical/occupational therapy (PT/OT) use.

Design: From a population of 2,003 chronic pain patients (CPPs) who acquired a TENS device (Epix XL, Empi, Inc., St. Paul, MN, U.S.A.) for pain management, a randomly selected sample of 376 patients who used TENS were interviewed by telephone by an independent research firm. The survey assessed a variety of outcome variables including changes in medication use, number of pain-related medications, and use of PT/OT prior to TENS and after a minimum 6 months of TENS treatment. The data were subjected to a paired t test analysis. A cost simulation model was then applied to the medication and PT/OT data.

Results: The mean duration of pain, for which TENS was prescribed, was 40 +/- 60 months. As compared with the period prior to TENS use, this long-term TENS user group reported a statistically significant reduction in the following types of pain medications: opiate analgesics, tranquillisers, muscle relaxants, nonsteroidal anti-inflammatory drugs (NSAIDs), and steroids. PT/OT use was also significantly reduced. Cost simulations of pain medications and PT/OT are presented.

Conclusion: Long-term use of TENS is associated with a significant reduction in the utilization of pain medication and PT/OT. In this study population, cost simulations of medication and PT/OT indicate that with long-term TENS use, costs can be reduced up to 55% for medications and up to 69% for PT/OT. The potential for TENS associated improvement, combined with reduced medication-related complications and costs are important points that clinicians should consider when constructing a treatment plan for chronic pain patients. Finally, cost simulation techniques provide a useful tool for assessing outcomes in pain treatment and research. PMID: 9535316 [PubMed - indexed for MEDLINE]
