Title: A Randomized Controlled Multicentre Trial of a Brief Intervention (BI) Versus a BI Plus Cognitive Behavioural Treatment (CBT) Versus Nutritional Supplementation for Patients With Long-lasting Back Pain.
Brief Summary: CINS is a large multicentre study which aims to test out the effect of 4 different interventions, namely a brief cognitive intervention (BI), a more extensive cognitive behavioural intervention (CBT), and 2 different nutritional supplementations (seal oil and soy oil) in a population of chronic low back pain patients sicklisted for 2-10 months.

3. Able to manage tolerably well to fill in forms.

Exclusion Criteria:

1. Temporary disability pension or disability pension being paid or in preparation.
2. A primary need of action by a hospital specialist.

4. Whiplash-associated disorders as a primary obstacle to working.
5. Previous rehabilitation at the rehabilitation centre.
6. Other multidisciplinary rehabilitation going on or planned.
B: Inclusion Criteria:

* Current episode of low back pain
* mechanical origin
* Threshold low back pain level

Exclusion Criteria:

* Contraindications to spinal manipulation or massage
* Complicating conditions that could confound clinical outcome
* Prophylactic use of prescription medication
* Health-related litigation, claims, or disability compensation
C: Inclusion Criteria:

1. Men or women who are skeletally mature.
2. Fracture of any extremity with complete radiographs.
3. Open fractures (Gustilo-Anderson Types I-IIIB) (Table 2)\*.
4. Fracture requiring operative fixation.
5. Provision of informed consent.

Exclusion Criteria:

2. Known allergy to detergents or castile soap ingredients.
3. Previous wound infection or history of osteomyelitis in the injured extremity.

11. Previous randomization in this study or a competing study.
