The Use of Transcutaneous Electrical Nerve Stimulation (TENS) for Chronic Pain of Predominantly Peripheral Neuropathic Origin

The aim of this study is to investigate the effectiveness of TENS in addition to routine care in patients with chronic pain of predominantly neuropathic origin, compared to treatment with routine care alone."

Hypothesis:

An eventually neuropathic pain component is needed to be identified and alleviated in chronic pain patients to improve the quality of rehabilitation.

0-hypothesis:

  • TENS is not better than than placebo, medication or standard rehabilitation program.
  • A neuropathic pain component does not demand special considerations in rehabilitation of chronic pain patients.

Study Overview

Detailed Description

Setting:

Skogli helse- og rehabiliteringssenter, Lillehammer, Norway. Center of Rehabilitation for chronic pain patients, rheumatic diseases and orthopedic postoperative patients.

Duration:

Until 18 months of intervention + 6 months of follow up and preparation.

Intervention:

Use of TENS during 3-4 weeks of hospitalization connected to multimodal rehabilitation (short-term efficacy). TENS or placebo-TENS is added to routine care.

Follow-up:

If patients want to continue the use of TENS/placebo-TENS at home, they will be offered to borrow equipment for 4 months. Questionnaires will be send at 2 and 4 months, both for the active group, the placebo group and for the group of patients who discontinued the use of TENS/placebo-TENS (long-term efficacy).

  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: 1
Subjects in this study arm will receive active treatment with Cefar TENS device which delivers therapeutic electrical currents 2-3x over sensory threshold in the area of pain.
Patients will be randomly allocated to a group with active-TENS and exercises, or to a group with placebo-TENS and exercises. The TENS will be used during 3-4 weeks of hospitalization. If patients want to continue the use of TENS/placebo-TENS at home, they will be offered to borrow equipment for 4 months.

Patients will be randomly allocated to a group with active-TENS and exercises, or to a group with placebo-TENS and exercises.

Active TENS: high-frequency modulated pulse duration stimulation Placebo TENS: manipulated device with impulses near sensory threshold.

Placebo Comparator: 2
Subjects in this study arm will receive placebo treatment with manipulated Cefar TENS device which delivers electrical currents just below sensory threshold in the area of pain.

Patients will be randomly allocated to a group with active-TENS and exercises, or to a group with placebo-TENS and exercises.

Active TENS: high-frequency modulated pulse duration stimulation Placebo TENS: manipulated device with impulses near sensory threshold.
