Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Change in Peak Torque of the Knee Flexors and Extensors at 60 Degrees per Second | Baseline (before stimulation) and immediately after the end of stimulation, on the single study day (Day 1) | Maximal strength is assessed as peak torque (newton-meters) during five consecutive maximal concentric knee flexion-extension cycles at an angular velocity of 60 degrees per second on an isokinetic dynamometer (Biodex System 4 Pro). The right and left knee flexors and extensors are assessed separately, with the right leg tested first. Change is calculated as the post-stimulation value minus the baseline value. | ClinicalTrials.gov |
| Primary | Change in Average Power of the Knee Flexors and Extensors at 180 Degrees per Second | Baseline (before stimulation) and immediately after the end of stimulation, on the single study day (Day 1) | Explosive strength is assessed as average power (watts) during five consecutive knee flexion-extension cycles performed with maximal speed and effort at an angular velocity of 180 degrees per second on an isokinetic dynamometer (Biodex System 4 Pro). The right and left knee flexors and extensors are assessed separately. Change is calculated as the post-stimulation value minus the baseline value. | ClinicalTrials.gov |
| Primary | Change in Work Fatigue of the Knee Flexors and Extensors at 180 Degrees per Second | Baseline (before stimulation) and immediately after the end of stimulation, on the single study day (Day 1) | Muscular endurance is assessed as work fatigue (percentage) during 20 consecutive knee flexion-extension cycles performed with maximal speed and effort at 180 degrees per second. Work fatigue = (1 - work in the last third of the repetitions / work in the first third) x 100. Higher values indicate greater fatigue. The right and left knee flexors and extensors are assessed separately. Change is calculated as the post-stimulation value minus the baseline value. | ClinicalTrials.gov |
| Secondary | Number of Participants With Stimulation-Related Adverse Effects | Immediately after the end of stimulation, on the single study day (Day 1) | Sensations and adverse effects related to stimulation (for example tingling, itching, burning sensation, headache and fatigue) are recorded with a transcranial electrical stimulation sensation questionnaire after the intervention. The number of participants reporting each adverse effect is summarized by group. | ClinicalTrials.gov |
