Abstract
So-called Cross Test in which a subject is asked to move his/her own center of gravity as a cross figure was applied in our experiment by measuring center of foot pressure (CFP). We have aimed to build the Cross Test systematically applicable to daily evaluations. This time, we were interested in if the test is valuable for that purpose. In a measurement system, we employed not 1 forceplate but 2 plates. This enabled us to find specific results on hemiplegics and amputees by measuring individual CFP on each foot.
We recorded postures with a right body alignment and a different one prior to the experiment to confirm our test posture. A reliability of the test was also analyzed. Finally, 50 normal subjects, 17 hemiplegics and 14 amputees were tested. Basic statistics, correlations between the data and the age and gait ability and time course of the data on a few particular patients were discussed based on the statistics.
We obtained reliable data independent on the difference in record time. There were statistical differences between load for the sound and affected sides of the hemiplegics and amputees. The amputees showed that their data of cross range depended on the gait ability. CFP locus pictures demonstrated that they became more and more complete as time went.
It is the most important point that the result of the Cross Test can be visually evaluated. In addtion to that point, we could show the typical aspects on the patients by analysing ICFP. It was concluded that the Cross Test can be effective for evaluating the severity of patients and therapy outcomes.
