[Contributions of robotic devices to upper limb poststroke rehabilitation].
BACKGROUND
Poststroke rehabilitation care has evolved considerably over the last decade. The emergence of the concepts of brain plasticity and motor learning has led to the development of new therapeutic approaches. Most of the new strategies are based on movement therapy, which can have a real impact on neurological recovery, sometimes with significant functional benefit for the patient.


BACKGROUND
In this context of evolving practices, the hemiplegic arm is the subject of special attention. Considering the often unfavorable "natural" prognosis and the relatively limited impact of conventional therapies; researchers have focused work on new alternatives. Cooperation between developers of technological advances and the medical community has led to the development of innovative therapeutic options often based on the use of specific technological tools (functional electric stimulation, virtual reality, transcranial magnetic stimulation...) to solicit or facilitate movement.
Robot-assisted rehabilitation lies within this scope. The positive results reported in the most recent publications and the growing interest for this type of therapy in the fields of medical and engineering research should open the way for extremely promising prospects. The technological performance of new robots has nevertheless raised a large number of unanswered questions, implying a significant amount of further research.
