Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A sumscore for trunk stability/function is to be formed from biomechanical measures (Center of pressure path: one leg stand; jump-power; peak torque of the trunk; Surface Electromyogram time and amplitude measures). The measurements will be done pre and post Intervention (6 weeks). | — |
Secondary
| Measure | Time frame |
|---|---|
| specific biomechanical measures are assessed pre and post intervention (6 weeks): - center of pressure (COP) path during one leg stand (Ground reaction force plate; AMTI). Quantified with the total displacement of the COP for 10s. - jump-power using counter movement jumps (Ground reaction force plate; AMTI). Quantified with the maximum force during push off (Fz). - maximum strength capacity of the trunk during trunkrotation and trunk flexion/extension (Dynamometer, Con-trex MJ/TP/WS). Quantified with peak torque. - muscular activity of the trunk muscles, quantified with surface electromyography (time-measures; on-off pattern) | — |
