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

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.
