Physiotherapy/exercieses according to the Rigo Concept, 5 days, 3 hour per day

Physiotherapy/exercises according to the Rigo Concept combined with whole-body vibration, 5 days, 3 hour per day, supplemented with 3 x 3 minutes of WBV, frequency 25 Hz, amplitude 2 mm

5-day physiotherapy based on the Rigo Concept. It has four general principles of correction such as three-dimensional stable postural correction, expansion technique, muscle activation, and integration. Intervention last for 3 hours per day.

The examination of spinal curvatures (degrees) in the sagittal plane is conducted using a Baseline digital inclinometer (MVS in Motion, Belgium). Measurements are taken in a relaxed standing position. The assessment includes evaluation of thoracic kyphosis (upper and lower parts), lumbar lordosis, and sacral slope. The procedure is as follows: 1) Thoracic kyphosis - the inclinometer is zeroed at the thoracolumbar junction (Th12-L1), and the value is recorded at the cervicothoracic junction (C7-Th1); 2) Lumbar lordosis - the inclinometer is zeroed at the lumbosacral junction (L5-S1), and the value is recorded at the thoracolumbar junction (Th12-L1); 3) Sacral slope - the inclinometer is zeroed in the horizontal position, and the value is recorded at the lumbosacral junction (L5-S1).

For postural alignment (centimeters), the physician positions a plumb line at the level of the occipital prominence. Measurements are performed using a rigid millimeter ruler and are rounded to the nearest 0 or 5 mm, assessing the distance from the plumb line to the gluteal cleft. For the assessment of scapular height asymmetry, the inferior angles of the scapulae are marked bilaterally. A rigid ruler is placed across these points, and a scoliometer is positioned on the ruler to record the angle of inclination (degrees). The distances from the inferior angles of the scapulae to the line of spinous processes are measured on both the left and right sides using a rigid ruler, and the differences (centimeters) are then calculated.

The measurements of the angle of trunk rotation in the transverse plane are conducted using a Baseline scoliometer (MoVeS, Poland). The angle of trunk rotation is assessed during the Adams forward bend test. The participant stands in a relaxed upright position and is instructed to keep their hands together and slowly bend forward, aiming their hands toward the center of support. The examiner records the angle (degrees) and direction (left/right) of trunk rotation at the proximal and main thoracic spine, thoracolumbar region, lumbar spine, and at the level of the posterior superior iliac spine.
