Outcome Measures

Primary Outcomes (2)

  • Pain Intensity

    Pain Intensity will be measured by an 11-point (0-10) Numerical Rating Scale (Pain NRS)

    5 weeks after randomization

  • Disability

    Disability will be measured by the 24-item Roland Morris Disability Questionnaire

    Five weeks after randomization

Secondary Outcomes (5)

  • Pain Intensity

    3, 6 and 12 months after randomization

  • Disability

    3, 6 and 12 months after randomization

  • Function

    Five weeks, 3, 6 and 12 months after randomization

  • Kinesiophobia

    Five weeks, 3, 6 and 12 months after randomization

  • Global perceived effect

    Five weeks, 3, 6 and 12 months after randomization

Other Outcomes (1)

  • Patient's expectancy for improvement

    Baseline

Study Arms (2)

Placebo

PLACEBO COMPARATOR

The patients allocated to the Placebo group will be treated with detuned pulsed ultrasound for 5 minutes and detuned short wave diathermy in pulsed mode for 25 minutes. Patients will receive 10 sessions of treatment over a period of five weeks (two sessions/week).

Other: Placebo

McKenzie method

EXPERIMENTAL

The patients of the McKenzie group will be treated according to the principles of the method and the choice of therapeutic intervention will be guided by the physical examination findings and classification. Patients will also receive written instructions from the Treat Your Own Back book and will be asked to perform home exercises based on the principles of McKenzie method. Patients will receive 10 sessions of treatment over a period of five weeks (two sessions/week).

Other: McKenzie method

Interventions

PlaceboOTHER

The patients allocated to the Placebo group will be treated with detuned pulsed ultrasound therapy for 5 minutes and detuned short wave diathermy in pulsed mode for 25 minutes. Patients will receive 10 sessions of treatment over a period of five weeks (two sessions/week).

Placebo

The patients of the McKenzie group will be treated according to the principles of the method and the choice of therapeutic intervention will be guided by the physical examination findings and classification. Patients will also receive written instructions from the Treat Your Own Back book and will be asked to perform home exercises based on the principles of McKenzie method. The description of the exercises that will be prescribed in this study are already published elsewhere. Compliance with home exercises will be monitored by means of a daily-log that the patient will fill in at home and bring to the therapist at each subsequent session. Patients will receive 10 sessions of treatment over a period of five weeks (two sessions/week).
