Abstract

Summary : Introduction: Rapid movement of the arm or leg is associated with contraction of the abdominal muscles prior to or shortly after the contraction of the muscles responsible for the initiation of the limb movement. This anticipatory contraction of the abdominal muscles is thought to contribute to preparatory stabilisation of the spine against reactive forces resulting from the limb movement. The purpose of this study was to investigate the effect of the arm swing and physical exercise on the postural stability. Method: Subjects: 16 healthy middle-aged (43.12 ± 2.14 years) voluntaries were involved in the study. Static postural stability was measured during standing on a force platform, and the effect of a rapid shoulder flexion on the sway parameters (displacement of centre of mass) was determined in medio-lateral (ML) and anteroposterior directions (AP). The subjects have taken part in a lumbar stabilisation program for 8 weeks. The posturographic measurements were performed before and after the training program. The data were processed by analysis of variance. Results: The absence of the visual control caused an increase in the body sway during the quiet standing before but not after the training programme. The arm movement caused a significant increase in the sway mainly in the anterior-posterior direction. The lack of the visual control initiated a further increase of the maximal amplitude in forward direction before the training. This significant difference has vanished after the training. Discussion: Our results suggest that physical training increased the postural stability not only during quiet standing but also at dynamic perturbations, because without visual control the subjects were more able to control the movement of their centre of mass. Our findings can be explained by the improved somatosensory inputs and/or the coordination among muscle.
