 Patients with stroke or disorders of consciousness DOC are likely to suffer from major muscular troubles such as spasticity. This spasticity may induce pain, loss in range of motion and permanent joint deformities. The aim of this study is to investigate the effects of soft splinting on the hand spasticity in both patients with stroke and patients with disorders of consciousness. The investigators plan to include 100 patients 50 stroke - 50 with DOC and each subgroup will be divided in two arms: one wearing real soft splints 6 cm diameter three hours a day for 3 three weeks and the other one wearing placebo splints 1 cm diameter.
