Table 4

Extents of activation for IBM patients and healthy controls. Activation in neuroanatomically defined volumes of cortex during bulb squeezing with the right hand for individual patients with inclusion body myositis and for healthy controls are shown. Values for the patients are listed in numerical order (see table 1) from the top down for the right hand.

Numbers of voxels
CMC, contralateral sensorimotor cortex; IMC, ipsilateral sensorimotor cortex; SMA, supplementary motor cortex; LI, lateralisation ratio. There were no significant differences between the patients and the healthy controls.
