Testing the effect of a specific stretch technique versus sham treatment, to objectify the influence of that specific technique on thoracic rotation mobility.

Subjects in the experimental group will undergo a technique for stretching the intrathoracic fascia. Before and after, a measurement will be performed with a goniometer, to see if there is a difference in thoracic rotation mobility.

Subjects in the placebo group get a different technique, where the hands of the therapists are simply placed on the thorax, but no manoeuvre will be performed. Before and after, there is a measurement in thoracic rotation mobility.

Data will be compared and statistical analyse will be done to see of there is a difference in rotation. So the hypothesis that stretching intrathoracic fascia has an effect on thoracic rotation mobility, will be accepted or rejected.
