The objective of KERAAL technological project is to create a new intelligent robot which allows a humanoid robot to record then to show and to follow the progress of rehabilitation sessions proposed by a physiotherapist to a patient, the latter being able to practice without the physiotherapist. The final objective is to stimulate and increase the overseen time of rehabilitation. Poppy robot was chosen as it is able to realize all kind of movements notably movements of the spine with 5 degrees of freedom associated to the several levels of the spine. It will allow to address the population included in the protocol. RCOOL study tries to validate this prototype device as tool of rehabilitation.

The main objective is the feasibility of the supervision by a humanoid robot of a succession of rehabilitation exercises.

RCOOL study is a randomized clinical trial checked under single-blind condition to compare two rehabilitation strategies, one with exercises executed by the patients and supervised by Poppy and the other one with usual rehabilitation protocol.
