Physiotherapy : This treatment has been shown to be effective, and is essential to reduce impairments and improve function in patients with hemiparesis following stroke (Robertson et al, 2008 ; Bourgeais et al, 2010). Different methods exist, and comparative studies of the most common ones have shown a similar effectiveness (Adal et al, 2006 ; Flansbjer et al, 2008 ; Brazzelli et al, 2011, Durstine et al 2009). No conventional treatment has been shown to be more effective than another. However, it has been demonstrated that the intensity and specificity of rehabilitation techniques are positively correlated with motor recovery (Gordon et al, 2004).
