In the article, the authors goal was to "investigate the effect of rhythm on the control of paretic arm movements in stroke patients." The basis for this intervention was prior research that had suggested that:
- "a rhythmic model of rehabilitative motor training, has shown significant improvements in gait function of stroke patients. In this model, rhythm functions as a sensory cue to induce temporal stability and enhance the temporal organization of motor control in the nervous system by translating the temporal structure of movement patterns into temporally isomorphic auditory rhythmic patterns to entrain the movement in question. Similar models have been successfully used in high-performance motor skill learning in sports and music."
- "the observed changes in timing and trajectory control strongly suggest that the structured time information in auditory rhythm added significant kinematic stability to the patient’s paretic arm reaching motions. These changes were not present during the non-rhythmic condition...Our data suggest, therefore, that auditory rhythm may offer an essential component of enhanced sensorimotor control to make hemiparetic arm training more effective."
