Stimulus zones of Vojta method and trunk control in children with spastic-type cerebral palsy: A quasi-experimental pilot study.

BACKGROUND

Vojta method improves motor function by inducing a response by pressing the stimulus zones.

PURPOSE

To determine the effect of the stimulus zones on trunk muscle thickness, trunk control, trunk angle, and gross motor function in children with spastic-type cerebral palsy.

METHODS

A quasi-experimental pilot study was conducted with 19 children with spastic-type cerebral palsy divided into two groups: Vojta method group (n = 10) and general physical therapy group (n = 9). Each group underwent a 6-week intervention, and assessments were conducted to evaluate abdominal muscle thickness, trunk control, trunk angle, and gross motor function.

RESULTS

In the Vojta method group, the change rate in the thickness of the internal oblique and transversus abdominis increased significantly within the group (P < 0.05) and the difference (post-pre) of the transversus abdominis was higher (P < 0.05). The trunk angle increased significantly within the group when thoracic 7 and 11, lumbar 3, and sacrum 1 were supported (P < 0.05). There was a significant difference in trunk angle difference (post-pre) between groups when thoracic 11 and sacrum 1 were supported (P < 0.05). Segmental assessment of trunk control and gross motor function measure-88 scores were significantly increased within the group in all groups (P < 0.05).

CONCLUSION

The stimulus zones of the Vojta method could improve trunk control in children with spastic-type cerebral palsy through intra-abdominal pressure and anti-gravity movement.
