The majority of hemiparetic patients have balance disorders, which impact independence in daily living activities and walking. Conventional techniques used in rehabilitation improve balance but have shown no effects on dynamic balance required during walking. Recently dance is proposed to improve dynamic balance in older people and people with Parkinson's disease. Although many studies showed that dance is an effective activity to improve balance in these people, it has never been assessed in hemiparetic patients (except a case report). The aim of this study is to show that a dance program improves the balance of hemiparetic patients, compared to a control group. This randomized controlled study aims to include 40 hemiparetic patients who will perform a dance program (experimental group) or a upper-limb rehabilitation program (control group) for 8 one-hour sessions.
