Proportional upper limb recovery after stroke is predicated upon corticospinal tract integrity

For most patients after stroke, upper limb impairment resolves by approximately 70% of the maximum amount possible i.e., the proportional recovery rule (PRR; Prabhakaran et al., Neurorehabil Neural Repair 2008 22: 64-71). This presentation will demonstrate how the PRR relies on corticospinal system integrity as determined with transcranial magnetic stimulation and diffusion-weighted MRI. Data were obtained from 48 patients previously enrolled in an upper limb rehabilitation interventional trial.
