Normalized motor evoked potentials (MEPs) were recorded using transcranial magnetic stimulation from the biceps of nonimpaired individuals and individuals with biceps transfer and tetraplegia to compare posture-dependent corticomotor excitability. MEPs were normalized to the horizontal plane posture with the forearm oriented in neutral for each subject. Please note the numeric descriptors in the data file for the main postures (horizontal plane, overhead reach, pressure relief), forearm orientation (neutral, supinated), and population (nonimpaired, biceps transfer and tetraplegia). Please see our publication for further details.

The purpose of this study was to quantify the ability of individuals to voluntarily activate transferred muscles during maximum isometric elbow extension. Here we share our voluntary activation and maximum elbow extensor moment data across functional postures in individuals with tetraplegia and either biceps-to-triceps transfer or posterior deltoid-to-triceps transfer. Numbers to differentiate individual arms in the data file corresponding to the arms of individuals described in Table 1 in our publicaiton. Please see our publication for details regarding the experimental protocol, data analyses, participant demographics, and relevance to rehabilitation.
