The effect of Schroth method as a physiotherapy scoliosis-specific exrecise in postural control of individual with adolescent idiopathic scoliosis: a single blinded randomized clinical trial

The effect of Schroth method in postural control of individual with adolescent idiopathic scoliosis

Randomized, superiority, two parallel group trial with blinded outcome assessment. Random size 4 blocked randomization stratified will use for the Schroth curve types and concealed randomization sequence carried out at an external site.

The assessment of patients' postural control in static stand position will perform in a laboratory of department of physical therapy in school of rehabilitation sciences of Iran University of Medical Sciences approved for biomedical research using a force plate. Patients will instruct to step onto the force plate and stand quietly with the feet shoulder width apart, hands at the side and look straight ahead at a white dot located at eye level 1.2 meters away. Trial will collect for 90 s in eyes open (EO) then in eyes closed (EC) conditions and will calculate the Romberg’s quotients (RQ: EC/EO).

Inclusion criteria: age range of 10-19 years, both genders, curves between 10-45, the primary curvatures in right and located in the thoracic spine. Exclusion criteria: accompanying mental problems or neurological-muscular or rheumatic diseases, a previous spinal operation, scheduled for surgery.

Schroth exercises for intervention group include: muscle cylinder, the frog at the pond, the door handle, raising the pelvis and 50x exercise will perform in one-hour sessions, combined with a 30±45 min daily home exercises program. Also standard care for intervention and control groups including observation after each 3 month for patients have curves 10-25 and brace daily (16h) for patients have curves 25-45 according to their curves.

The primary outcome consists of center of pressure's sway and position variables for assessment of postural control.

Method of randomization is 4 block, unit of randomization is individual, randomization strata according to number of curves is startified randomization, then patients will divide in intervention group (group A) and control group (group B) and two list of random allocation that consist of A and B letters will locate in sealed envelops. Each numbered envelope will be according to patient's number.

This trial is a single blinded randomized clinical trial. A physical therapist as an assessor that will assess postural control, SRS-22r questionnaire and angle of trunk rotation is blind.

Deidentified individual participant data collected for the primary and secondary outcome measures will be shared if necessary.

Starting 6 months after publication

The data will be available for physical therapists working in academic institutions and also clinicians working in the field of musculoskeletal disorders

The raw data and results of this study can be used in future relevant systematic reviews. Thus, the raw data and results of this study will be available for researchers working in the field of scoliosis.
