[Residual postural changes after cranial trauma]

Abstract

A group of 29 clinically stable post-traumatic brain injury patients were studied for postural disturbances utilizing both a balance force platform and the Tinetti equilibrium test. The stabilometric exam included 6 different aspects of balance, with the goal of evaluating the importance of the sensory afferents on postural control. Posturographic data revealed a global reduction of postural control. TBI patients tended to rely more on visual feedback in postural control than did age-matched controls, and exhibited problems with sensory integration as the complexity of the balance tasks was increased. The site of lesion correlated positively with postural control problems, with brainstem and subcortical gray matter lesions most frequently being involved.
