MeasureTime frame
Mean normalized iEMG of the ipsilateral transversus abdominis, multifidus, and gluteus medius in the four time windows (APA1, APA2, APA1, and CPA2). Timepoint: APA1 : -250 to -100 milliseconds, APA2 : -100 to +50 milliseconds, CPA1 : +50 to +200 milliseconds, CPA2 : +200 to +350 milliseconds. Method of measurement: Electromyography.;Mean normalized iEMG of the contralateral transversus abdominis, multifidus, and gluteus medius in four time windows (APA1, APA2, CPA1, and CPA2). Timepoint: APA1 : -250 to -100 milliseconds, APA2 : -100 to +50 milliseconds, CPA1 : +50 to +200 milliseconds, CPA2 : +200 to +350 milliseconds. Method of measurement: Electromyography.;Mean onset latency of the ipsilateral transversus abdominis, multifidus, and gluteus medius. Timepoint: The time interval between perturbations (time 0) and the time of onset of muscle activity.
