These results were further confirmed in a study which used goal attainment scaling as an outcome measure (Turner Stokes et al, 2010). Following BTI in the upper limb of hemiparetic patients, there was a significant improvement in the goal attainment scaling score which was, moreover, strongly correlated with the reduction in spasticity evaluated with the Ashworth scale (most widely used scale for the evaluation of spasticity). The results also showed that the goal was more often attained when it involved the improvement of a passive function than an active function. The only study to have shown an improvement in prehension following BTI involved combined treatment with constraint induced therapy (Sun et al, 2010).
