Paper Abstract

A primary aim in the physical rehabilitation of individuals with severe head or spinal injuries resulting in hemiparesis, tetraparesis or paraparesis, is the restoration of the functional motor abilities controlling involved muscle groups. The regaining of trunk postural stability provides a valuable antecedent in the recovery of use of the arms and legs. Accurate objective infor-mation must be provided to the therapist for assessment of treatment regimes. At present, few objective practical methods are available to furnish this evaluative information. Therefore the purpose of this study was to investigate the use of a biostereometric range of motion sensor for recording and quantifying trunk static equilibrium in individuals ungergoing therapy for head trauma. The sensor located the relative position of the C-7 vertebrae of the patient in space using continual monitoring of spherical coordinates. Results of the test protocol included : plots of the movement of the trunk excursions, determination of the maximum area of excursion and a trunk sway index (the relationship of the maximum area, the total excursion distance and a time factor). Further results demonstrated that the biostereometric sensor yielded quantitative documentation of improvement in a patient undergoing therapy.
