Pain Reducing Effect of Transcutaneous Electrical Nerve Stimulation in Patients With Chronic Low Back Pain or Lumbo-radiculalgia

Pain Reducing Effect of Transcutaneous Electrical Nerve Stimulation (TENS) in Patients With Chronic Low Back Pain or Chronic Lumbo-radiculalgia and Followed in Pain Treatment Centers

Prior studies showed contradictory results about the best type of TENS in chronic pain pathology.

Therefore we want to evaluate the efficacy assessment of TENS on patients with chronic low back pain or chronic lumbo-radiculalgia.

The functional ability score is evaluated by the Roland scale at 6 weeks.

Inclusion Criteria:

• Stable chronic low back pain or stable chronic lumbo-radiculalgia
• Patients with a pain score at least superior or equal to 4
• Patients followed in pain clinics
• Written informed consent

Exclusion Criteria:

• Prior ambulatory TENS practice
• Lumbo-radiculalgia pathology surgery within 3 months before inclusion
• Acute low back pain or bilateral lumbo-radiculalgia
• Acute radiculalgia
• Surgery planned within 6 months
• Pacemaker
• Symptomatic low back pain
