THE INFLUENCE OF EXTERNAL LOADING ON WEIGHT COMPENSATORY CHANGES AND PELVIC BEHAVIOUR DURING WALKING IN SCOLIOTIC CHILDREN
Journal Title: Fizjoterapia Polska - Year 2008, Vol 8, Issue 4
Abstract
[b]Background.[/b] Compensatory changes in the spatial arrangement of body segments are a characteristic sign of the development of scoliosis. Additional external loads may lead to intensification of existing signs in both static and dynamic conditions. The manner of carrying heavy objects on a daily basis is a key factor here. The aim of this paper was to assess some changes in static and dynamic parameters associated with carrying the school pack in children with scoliosis.[b]Material and methods.[/b] Thirty-six children aged 8-15 years with low-grade scoliosis were examined. Foot pressure in static conditions was recorded using a force platform without additional loading, and with a 4 kg external load carried in a symmetric or asymmetric manner. Three-dimensional gait analysis was also performed using a Zebris® system. Parameters were registered during walking without and with the external load.[b]Results.[/b] Signs of asymmetric foot pressures were observed that intensified during external loading of spine (both symmetric and asymmetric). These changes were not clearly related to body posture parameters. There were also signs of gait asymmetry that intensified during walking with asymmetrical external loading. The most marked changes were observed with respect to pelvis-related gait determinants. The magnitude of changes was related to the manner of carrying the school pack rather than to body posture parameters.[b]Conclusions.[/b] External loads intensify the asymmetry of foot pressure distribution as a result of spontaneous and unpredictable compensatory dislocations. The manner of carrying the school pack is not irrelevant in children with scoliosis.
