Design outcomes

Primary

Measure	Time frame
Electromyographic activity of the internal oblique muscle of the abdomen. Timepoint: Baseline (pre-test) and after 8 weeks (post-test). Method of measurement: Surface electromyography (Cometa, Italy) with disposable surface electrodes according to the SENIAM protocol. Electrodes are placed 2 cm medially and 2 cm inferior to the anterior superior iliac spine, parallel to the inguinal ligament and lateral to the rectus sheath. Activity is recorded during quiet standing for 1 minute; the first and last 15 seconds are discarded and the middle 30 seconds are analyzed. Values are normalized to the maximum voluntary isometric contraction of the internal oblique muscle (in side-lying position with trunk rotation).;Electromyographic activity of the rectus femoris muscle. Timepoint: Baseline (pre-test) and after 8 weeks (post-test). Method of measurement: Surface electromyography (Cometa, Italy) with disposable surface electrodes according to the SENIAM protocol. Electrodes are placed at 50% of the distance from the anterior superior iliac spine to the superior part of the patella on the dominant leg. Activity is recorded during quiet standing for 1 minute; the first and last 15 seconds are discarded and the middle 30 seconds are analyzed. Values are normalized to the maximum voluntary isometric contraction of the rectus femoris muscle (in seated position with resistance applied to the lower leg).;Craniovertebral angle. Timepoint: Baseline (pre-test) and after 8 weeks (post-test). Method of measurement: Photogrammetric method using a digital camera mounted on a tripod at a distance of 1.4 m from the participant. Reflective markers are placed on the tragus of the ear and the spinous process of the seventh cervical vertebra. The angle between the horizontal line and the line connecting the two points is calculated using image analysis software.;Thoracic kyphosis angle. Timepoint: Baseline (pre-test) and after 8 weeks (post-test). Method of measurement: Photogrammetric method us	—
