• Resumen

  • Individuals with spastic cerebral palsy (CP) typically keep upper limb flexion, which causes disadvantages during running. This study evaluated a portable auditory biofeedback device to increase the acceleration of the affected upper limb in runners with CP, verifying if the need of feedback decreases and the speed of running increases. Two male hemiparetic athletes executed 2 weekly trials in an athletics track. The device fired an auditory signal each time the acceleration was under the set threshold. The firing number of the Athlete 1 tended to fall, which evidences that he learned to run with greater acceleration of the affected limb, decreasing the need of correction. His track time tended to fall, but we cannot affirm that it was due to the new movement pattern. The Athlete 2 presented little needed correction and no firing in most of trials. Therefore, he did not change his movement pattern.
