Many study exits (many deaths, aggravations) that we had anticipated (but not enough). The patients did not stay long enough in the department to complete the protocol (many study exits that we had not anticipated).

Functional recovery is one of the main issues in the management of stroke and there are various ways in rehabilitation to promote this recovery.

Verticalization is a technique whose benefits have been widely demonstrated, particularly in neurology. Although commonly used in the rehabilitation of stroke, evidence is still lacking as to its impact in this specific care.

Verticalization is underutilized in two situations: in the hyper acute phase as well as in elderly and very deficient patients. It has, however, been shown that the precocity of the treatment allows a better functional recovery. Similarly, the re-education of the elderly is also debated since it has long been mentioned that age was a factor of poor prognosis, the objectives are sometimes underestimated. However, several studies have shown that with the same rehabilitation, elderly patients recover as much as younger patients. The differences found are at least in part due to "less rehabilitation" of older stroke patients.

The different existing data lead us to the hypothesis that the verticalization of the elderly hemiplegic patient in acute phase would allow a better functional recovery.
