This is a study for a new mechanical transport device adapted to the hemiplegic patients.
Healthy volunteers :
After explaining the protocol and presenting the movement laboratory, the subjects are equipped with reflective markers on the 4 limbs, the trunk and the head. The subjects are installed on a seat positioned in front of 2 force platforms installed on the ground. The seat is equipped with a force platform.
Phase 1 :
After being seated, the subject realizes :
* 3 seat to stand and stand to seat without assistance
* 3 seat to stand and stand to seat using a handle located in front of it (handle equipped with a 6-axis force sensor)
* 3 seat to stand and stand to seat using the experimental device This phase will last 45minutes (mn) (30mn of equipment and 15mn of sitting passengers standing)
Phase 2:
After being seated, the subject performs a course comprising:
* A standing pass from sitting on a chair
* A straight line movement
* A succession of left and right turns
* An upward and downward travel of less than 1%.
* Standard doorway
* Standing on the toilet
* A sitting pass from the toilet
* One way to a bed
* A sitting pass on the bed
* A passenger seat sitting upright from the bed
* A return to the starting point
* A sitting pass on the starting chair Each stage is timed. A subjective analysis of each step is done by a lickert scale on the perceived comfort and safety.
This phase 2 will last 30mn (15mn of course and 15mn of questions).
Hemiplegic subjects :
At each session, the subject is examined by a physician who evaluates the motor control (Fugl Meyer scale), the equilibrium (Berg scale) and the spatial hemineglect (Bergego scale).
Phase 1 is performed except the 3 seat to stand and stand to seat without assistance which are impossible.
Phase 2 is performed. An evaluation of the device over 4 hours is carried out for each subject in therapeutic apartment in simulated living conditions. The validation in living lab is carried out by an ergonomist and by a questionnaire on the comfort and safety of the various steps identified by the ergonomist.
