Brief Summary:

The purpose of this study is:

  • Epidemiological part: characteristics of low back pain patients from a forestry company in Finland. Data is collected from occupational health databases and self administered questionnaires.
  • Intervention: To determine the effectiveness and cost-effectiveness of several different interventions in subacute low back pain (LBP) patients in occupational health (OH).

Condition or disease Intervention/treatment Phase
Low Back Pain, Recurrent Low Back Pain Other: Moderate Other: Mild Other: Mild vs. NC Other: Moderate vs. NC Not Applicable

Detailed Description:

Eligible subjects were divided into two randomised controlled trials with the name of "mild" or "moderate" low back pain trials (interventions) and also mild vs natural course (NC) and moderate vs. NC interventions.

Pain, disability and quality of life were collected up to 2 years by self-administered questionnaires and sickness absences were gathered from electronical records for at least 4 year's follow up time.

Arm Intervention/treatment
Active Comparator: BB

Subjects received the back book booklet, which is an self-information booklet about managing low back symptoms.

Included in the Mild and Mild vs. NC interventions.

Other: Mild
A one level intervention with long-term effectiveness and cost-effectiveness was executed for patients suffering from non-acute mild level LBP in occupational health. Patients were selected by using a self-administered postal questionnaire.

Other: Mild vs. NC
A two level intervention with long-term effectiveness and cost-effectiveness was executed for patients suffering from non-acute mild level LBP in occupational health. Intervention arms were compared to NC - no intervention group.

Experimental: BB+A

Subjects received a back book booklet and also oral advice based on the back book by the occupational health professional (OH Nurse or OH Physician in mild or moderate intervention, respectively).

Included in the Mild and Mild vs. NC interventions. Arm was also used as a control at the Moderate and Moderate vs. NC interventions.

Other: Moderate
A two level active intervention with a control group was executed for patients suffering from non-acute, moderate LBP in occupational health. Patients were selected by using a self-administered postal questionnaire.

Other: Mild
A one level intervention with long-term effectiveness and cost-effectiveness was executed for patients suffering from non-acute mild level LBP in occupational health. Patients were selected by using a self-administered postal questionnaire.

Other: Mild vs. NC
A two level intervention with long-term effectiveness and cost-effectiveness was executed for patients suffering from non-acute mild level LBP in occupational health. Intervention arms were compared to NC - no intervention group.

Other: Moderate vs. NC
A three level intervention with two control groups was executed for patients suffering from non-acute, moderate LBP in occupational health. RCT intervention groups were compared to NC group - i.e. no intervention.

Experimental: DBC
A graded activity back school program was carried out in a physiotherapy out-patient clinic that consisted of one-hour session twice or three times per week, lasting for 12 weeks, supervised by a specially trained physiotherapist. Arm is included in the MOderate and Moderate vs. NC interventions.
Other: Moderate
A two level active intervention with a control group was executed for patients suffering from non-acute, moderate LBP in occupational health. Patients were selected by using a self-administered postal questionnaire.

Other: Moderate vs. NC
A three level intervention with two control groups was executed for patients suffering from non-acute, moderate LBP in occupational health. RCT intervention groups were compared to NC group - i.e. no intervention.

Experimental: PMU
An intensive, multidisciplinary LBP rehabilitation program was carried out in a physical medicine out-patient unit at the local Central Hospital. The program included a 3-week pre-course of 1,5 hour session at 3 days per week, closely followed by a 3-week intensive rehabilitation course of 6.5 hours per day for 5 days per week. A personal graded activity training program was made for each subject and patients were later called for follow-up visit within 1 year of the initial course. Arm is included in the MOderate and Moderate vs. NC interventions.
Other: Moderate
A two level active intervention with a control group was executed for patients suffering from non-acute, moderate LBP in occupational health. Patients were selected by using a self-administered postal questionnaire.

Other: Moderate vs. NC
A three level intervention with two control groups was executed for patients suffering from non-acute, moderate LBP in occupational health. RCT intervention groups were compared to NC group - i.e. no intervention.

Placebo Comparator: NC
Natural course of low back pain
Other: Mild vs. NC
A two level intervention with long-term effectiveness and cost-effectiveness was executed for patients suffering from non-acute mild level LBP in occupational health. Intervention arms were compared to NC - no intervention group.

Other: Moderate vs. NC
A three level intervention with two control groups was executed for patients suffering from non-acute, moderate LBP in occupational health. RCT intervention groups were compared to NC group - i.e. no intervention.
