Fig 2.

Brain activity associated with mental practice only. Images reflecting the activations in 4 subtractions. The top row of images depicts the sites of activation by subtracting the rest condition from the actual movement of the right hand condition (A) pretreatment (move affected > rest) and (B) posttreatment (move affected > rest). The second row depicts the sites from the subtraction of the rest from imagine moving the right hand condition both (C) pretreatment (imagine move affected > rest) and (D) post-treatment (imagine move affected > rest). Note (B) increased contralateral cortical activation and (D) increased bilateral cortical activation postintervention. Shown are all activations that passed a criterion of P <.001 uncorrected for multiple comparisons with an extent threshold of 0.
