Influence of Physical Functions on the Center of Pressure in the Single Elbow Support Position and the Rising up Maneuver in Patients with Hemiplegia

Abstract

For 21 hemiplegia patients we measured the rising up maneuver time and the center of pressure (COP) in the single elbow support position to find out which physical functions influence it and prevent the rising up maneuver, for treatment strategies. The rising up maneuver time and COP in the single elbow support position using a force plate under the static and dynamic conditions were measured. For the physical function, we measured the range of motion of trunk rotation, hemiplegia motor function, flaccidity of the shoulder girdle on the hemiplegic paralysis side, trunk rotation muscle strength, motor functions of the neck, trunk and pelvis, COP of the muscle strength of upper limb in the single elbow support position and in sitting on the edge of a bed position under static and dynamic conditions. The rising up maneuver time had a significant negative correlation with COP Y axis maximal movement distance (YD) in the single elbow support position under the dynamic condition. For stepwise multiple linear regression analysis, range of motion of trunk rotation, hemiplegia motor function, flaccidity of the shoulder girdle on the hemiplegic paralysis side, COP of the muscle strength of upper limb in the single elbow support position and sitting on the edge of a bed position under static and dynamic condition were adopted for YD interpretation. The analysis suggests dynamic stability in hemiplegia patients is a factor in performing a rising up maneuver smoothly. Furthermore, performing a rising up maneuver smoothly needs complex physical functions requiring multi-faceted approaches to each individual case.
