Summary:
The study design is a randomised, controlled, parallel, two-arm trial. The subjects are randomly assigned to one of the study groups: the intervention group or the control group. The study will analyze the applicability of the tensegrity principle in the massage therapy. The main aim of this study is to examine if the tensegrity principle can be used in massage therapy to increase the effectiveness of the intervention. Contractile and passive mechanical properties are assessed before and after the intervention.
