Charakteristik der Gangart bei lumbosakraler Diskopathie

Abstract

Objective: The aim of this study was to analyse patterns of ground reaction forces during walking in pathology of lumbar spine. Methods: In research took part 42 inpatients and 30 healthy person (control group), Academy of Physical Education students. Patients were divided into 3 groups: L4/L5, L5/S1 and L4/L5/S1 depending on the damage of an intervertebral disc level. By means CDG (Computer Dyno Graphy) system perpendicular component of ground reaction forces under foot were measured. For all 8 sensor in-built in sole of each measure shoe time of maximal force and its value were determined. Sum of values, recorded by sensors under forefoot and rarefoot were evaluated. Compared were left and right lower extremities of control group, affected and non-affected lower limb and the same extremities for all group. Results: For all patient groups affected lower extremity was loaded later then non-affected and later then the „healthy leg” in control group members. Typical for L4/L5 discopathy is decrease of force under back part of the foot and increase under forefoot. Contrary results in L5/S1 group were obtained. In a few cases changes of non-dysfunction side were observed. Conclusions: Weakness of peripheral muscles as an effect of lumbar spine diseases influences on force distribution during gait. In case when clinical evaluation improves, remained defective walking pattern may by a reason of spine overload and return of the pain. In physical examination gait analyse is useful tool, which could help prevent that.
