2.  To evaluate the effect of therapy with DENAS (dynamic-electro- neuro-adaptive-stimulation) in patients with unspecific chronic neck pain Design:  Bicentre observational study  Standard treatment + DENAS  NSAID intake unchanged  Standardised study protocol  Informed consent  Setting: In-patients of an 1. Orthopaedic rehabilitation clinic (clinic 1: male and female) 2. Rehabilitation clinic for mother and child (clinic 2: only females)

4. Inclusion  Age: 25-70 years  Chronic unspecific neck pain as main/add. diagnosis  Visual analogue scale (VAS) for pain between 3-10 cm at day of inclusion Exclusion  Specific neckpain  Inflammatory or rheumatic disease  Somatoform pain disorder  Metallic implant in the upper body area  Uncontrolled arterial hypertension  Larger skin injuries or acute skin diseases in the cervical spine area  Acute infection, tumor  Recent postoperative state in the cervical spine area  Alcohol or substance abuse  Recent aplication of acupuncture, neural- or electrotherapy in the cervical spine region

5.  VAS (10 point scale): Main evaluation parameter  SES (standard pain perception scale, sensory and affective subdivision) (Edgar Geissner: Hogrefe 1996)  General rating of tolerability (patient)

13.  During rehabilitation DENAS is an effective and well-tolerated treatment for patients with chronic unspecific neck pain.  It can be integrated without any problems into the regular treatment process in rehabilitation clinics in Germany.  During rehabilitation, treatment with DENAS is able to substitute other time consuming or personnel-intensive treatments
