Brief Summary

Sciatica pain is associated with a disc disorder in 85% of cases. Sciatica is shown to resolve without treatments in the majority of cases. Spontaneous regression of the intervertebral disc herniation occurs where the herniation loses its volume partly or totally without surgical interventions. It has estimated that only 5 to 20% of patients with symptomatic intervertebral disc herniation require surgery. Most trials comparing surgical trials and conservative treatments of sciatica due to intervertebral disc herniation favor surgery, because it results in earlier relief of pain. However, one year after surgery, there were only a few differences in pain and disability between surgery and conservative treatment groups. It has shown that the number of surgeries (discectomies) decreased among patients with sciatica when treated by using a mechanical diagnosis and therapy approach (MDT) also called the McKenzie method. In addition, by using the MDT method it has also been shown that sciatica patient who were clinically classified as "centralizers" had good to excellent non-surgical outcomes and many of them avoided surgery, whereas non-centralizing pain has shown to predict worse treatment outcomes, chronic low back disorder and disability. Further, patients who do not have centralization will be 6 times more likely to undergo surgery.The primary aim of this multicenter randomized clinical trial is to find out how many patients with sciatica due to intervertebral disc herniation with radicular symptoms for at least 6 weeks, and who are on the waiting list for surgery, avoid surgery by treatment using the McKenzie method compared to advice to stay active. Secondary aims are to compare the patients' self-reported outcomes such as low back and leg pain intensity, disability, work ability, sick-leave days, fear avoidance beliefs, kinesiophobia, depression and quality of life. The outcomes are measured at baseline, two and three months in the non-surgical patients. In addition, in the patients who have surgery the outcomes are measured at baseline and the day before and one month after surgery. Follow-up measurements are at 12 and 24 months

Study Arms (2)

McKenzie - method group

EXPERIMENTAL

Participants will be sent to an experienced MDT therapist for therapy. They are 1) assessed clinically, 2) treated according the MDT-approach which includes home exercise program, consisting i) an educational component, and ii) an active therapy component with directional preference exercises, several times a day with sustained end range positions according to symptom response, and with avoiding aggravating positions. Participants have a maximum of 7 treatment visits. They will also have physiotherapy counselling at study entry about the good prognosis of sciatica.

Behavioral: McKenzie Method

Advice to stay active group

ACTIVE COMPARATOR

Participants enrolled into this group will receive physiotherapist's counselling at study entry for at least 60 minutes time about the good prognosis of sciatica, the spontaneous regression of the intervertebral disc herniation and pain tolerance ("natural healing"). In addition, they will get ergonomic advice and advice to stay normally active. The participants are also told to avoid bed rest and advised to continue their normal routines as actively as possible including exercise activities with limits permitted by their signs and symptoms. A two-page summary booklet related to these items will be given to them.

Behavioral: Advice to saty active
