Abnormal Postural Balance and Gait in Adolescent Idiopathic Scoliosis – Correlation with Somatosensory Cortical Evoked Potentials

Postural balance (PB) & gait pattern (GP) were tested in 18 AIS girls (normal posterior tibial nerve somatosensory cortical evoked potentials “PTN-SCEPs”, N=10; abnormal PTN-SCEPs, N=8) and 8 control girls, with mean age at 14.5-y, by using two forced-platforms and 3-D motion analysis system respectively. All AIS girls had significantly poorer stability control (p<0.05). Furthermore, AIS with abnormal PTN-SCEPs had additional asymmetric kinetic GP (P<0.05).
