Digital therapy may provides real time visual feedbacks. Instrumented devices objectively quantify the patient's performance during rehabilitation and thus could be helpful for the personalization of the exercises.

The interactive ball of this trial allows measuring both movement and pressure applied on it. Therefore, the objectives of this study are: (i) to evaluate whether the use of a novel digital therapy gaming system was therapeutically relevant during shoulder rehabilitation; (ii) to understand whether the device was effective in improving patients' engagement in comparison to a control non-gaming rehabilitation program.
