E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Assess the difference between one-time topical application of verum and placebo regarding the effect and the onset of action in treating DOMS of the biceps brachii muscle.Variable for it is the change of PPT, measured before and after the muscular exercise of the upper arm musculature (v1 and v2) as well as several times within 4 hours after application of verum and placebo (visit2) determined by using an electronic pressure algometer.Further the movement pain in the upper arms of the subjects (VAS) to the times indicated above as well as the pain-free mobility in the elbow joints are determined and evaluated in the group comparison. Global evaluation of the clinical effect and tolerability as well as the occurrence of adverse events are documented and evaluated. The exploratory approach is chosen because there are no previously literature data concerning the effect of the investigational product in DOMS. It is an initial collection of basic data for the generation of specific issues. |
Unterschied zwischen der Anwendung von Verum und Placebo hinsichtlich der Wirkung und des Wirkungseintritts bei DOMS. Zielvariable ist die Änderung der Druckschmerzschwelle (PPT). Diese wird vor und nach der muskulären Belastung der Oberarmmuskulatur (V1 und V2) sowie mehrmals innerhalb von 4h nach Anwendung des Prüfpräparats bzw. Placebos (V2) durch algometrische Messungen ermittelt. Weiterhin werden die Bewegungsschmerzen in den Oberarmen mittels VAS zu den oben angegebenen Zeitpunkten sowie die schmerzfreie Beweglichkeit in den Ellbogengelenken ermittelt und im Gruppenvergleich ausgewertet. Dokumentation und Auswertung der globalen Beurteilung der Wirkung und Verträglichkeit; Auftreten unerwünschter Ereignisse.
Der explorative Ansatz zur Auswertung dieser Pilotstudie wird gewählt, da bislang keine literaturbekannten Daten zur Wirkung des Prüfpräparats bei DOMS vorliegen, so dass erstmalig Basisdaten für die Generierung spezifischer Fragestellungen zu erheben sind.
