To assess whether the locations of peak activation in the motor cortex differed between groups (knee OA vs control) for any of the three motor tasks (knee vs ankle vs hand) in any of the three planes, separate 2 × 3 mixed analysis of variance (ANOVA) (group x task) was performed for each image plane (X, Y and Z).
Participants were presented with six visual conditions in which visual stimuli (video vs static image), view (whole person vs hand) and grasp (precision grip vs whole hand grasp) were varied in a 2 × 2 × 2 factorial design.
These methods have been validated among 300 patents under palliative care in Africa with a correlation of around 0.9 for verbal vs hand scoring methods for both pain scores and symptom scores.
This latter result is highly consistent with the coding of differences in the hand kinematics required to operate the tool vs hand alone and accords with the presumed role of motor cortex in generating muscle-related activity (Kalaska, 2009; Churchland et al., 2012; Lillicrap and Scott, 2013).

Pink traces and bars denote accuracies that were computed by training classifiers to discriminate hand trials (Hand-G vs Hand-R) and testing on tool trials (Tool-G vs Tool-R).
Across-effector decoding accuracies (in purple) were computed using all the available data and from training classifiers on Hand-G vs Hand-R trials and testing on Tool-G vs Tool-R trials and then averaging these values with the opposite train-and-test ordering, within each subject.
We capitalized on this fact in order to characterize different brain regions according to the types of upcoming movements they could predict: Hand-G vs Hand-R and/or Tool-G vs Tool-R.
For each subject and for each of the ten action-related ROIs in the Motor experiment and three perception-related ROIs in the Localizer experiment, separate binary SVM classifiers were estimated for MVPA (i.e., for each pair-wise comparison, Hand-G vs Hand-R and Tool-G vs Tool-R, and for each time point).
DOI: http://dx.doi.org/10.7554/eLife.01273.005 Even though activations used to generate these two contrasts were measured during movements of different limbs (hand vs arm), and on different sides of the body (limbless side vs intact side), the differential activation was restricted in both cases to the hand area, as demonstrated by activation patterns in the control group.
A 2 × 2 repeated measures ANOVA was applied to all dependent variables with manual condition (uni- vs bimanual) and hand used (dominant vs non-dominant) as independent factors.
The current findings would suggest that such forward-state estimations, at least at the level of occipitotemporal cortex, remain linked to the type of effector (hand vs tool) to be used in an upcoming movement.
