Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Transversus abdominis Quotient (TAQ). TAQ is calculated by dividing the thickness of the transversus abdominis (TA) during forceful hip adduction by the thickness of the TA during Active Straight Leg Raising (ASLR) (left and right average). In formula: TAQ = thickness of TA during adduction / ((thickness of TA during ASLR left + thickness of TA during ASLR right) / 2) | — |
Secondary
| Measure | Time frame |
|---|---|
| The thickness increase of the TA (in % of the thickness at rest) at 7 low levels of hip adduction force (20-140 Newton). Force increase at bilateral hipadduction in % after fastening a pelvic belt. | — |
