Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the efficacy of the McKenzie method in patients with chronic non-specific low back.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

One hundred and forty-eight patients will be randomly allocated to two treatment groups: McKenzie method or Placebo (detuned ultrasound and short wave therapy) for 5 weeks (total of 10 sessions of 30 minutes each).

The clinical outcomes will be obtained at the completion of treatment (5 weeks) and at 3, 6, and 12 months after randomization. The data will be collected by a blinded assessor. The statistical analysis will follow the intention-to-treat principles and the between-group differences will be calculated by constructing mixed linear models.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Placebo

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).

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type OTHER

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).

McKenzie method

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).

Group Type EXPERIMENTAL

McKenzie method

Intervention Type OTHER

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).
