Revision of posturography based on force plate for balance evaluation.

BACKGROUND The maintenance of balance and body orientation in humans is guaranteed by the adequate functioning of the postural control system. The investigation of this control has awakened the interest of professionals from several fields such as Physical Therapy, Physical Education, Engineering, Physics, Medicine, Psychology, and others. OBJECTIVES The purposes of this study are to revise the methods of data analysis used to investigate the postural control in human beings and to demonstrate the computational algorithms of the main measures used in the postural control evaluation. CONCLUSION The experimental procedures and measures used in postural control evaluation presented in this review can help in the standardization of postural control investigation.
