Description of intervention(s) / exposure
McKenzie Group

Physical therapists were instructed to follow exclusively the treatment principles described in McKenzie's textbooks and not to use other treatment modalities. After testing the participants' pain response to a comprehensive physical examination, therapists will classify each patient into one of the three McKenzie syndromes (derangement, dysfunction, or postural) and an individualized treatment programme matching this classification will be then provided.

Patients will receive an individualised treatment for 30 minutes a day, once a week over four weeks.

Back school classes

Patients will receive interactive group classes (the sizes of the gropus will not exceed 4 patients) aimed to improve posture, avoid bed rest and increase activity. These classes will be administered by a trained physiotherapist.

Patients will receive an individualised back school class (30minutes duration) , once a week over four weeks.
