Reaction to the sensory integration therapy in children with postural stability deficits

The goal was to examine the influence of sensory integration therapy (SIT) on one leg standing in children with deficits of the postural stability.

28 children 4-6 year old that could not stand on one leg for more than 20 seconds were randomly divided into control "C" and experimental "E" groups. Group "C" participated in standard classes in the kindergarten. Group "E" participated in sensory integration therapy (SIT) for 2 weeks, 5 times a week (additionally to the standard classes).

Results of the experiment show that the skill of standing on one leg has significantly improved (P<0.01) in the group that underwent additional therapy. The change in time of standing on the right leg with eyes open in the E group was statistically and significantly higher than the changes observed in the same time in group C (F=22.5, P=0.001' η²=0.44). Similarly, significant changes in time of standing on the right leg with eyes closed were observed in group E. The foregoing changes were bigger in group E than in group C (F=16. 1, P=0.004, η²=0.36). The analysis post hoc revealed that while there were no significant differences between the two groups on the pretest (P>0.05), there were significant differences between groups in right leg standing test with eyes open or closed on posttest. (P<0.05). Similar results were observed during on the one, left leg standing. The time of one leg standing with both eyes open and closed improved more significantly in group E than in group C (F=20.4, P=0.001, η²=0.42 respectively for the test with eyes open and F=7.4, P=0.010, η²=0.21 for the test with eyes closed). The analysis post hoc revealed that while there were no significant differences between the two groups on the pretest (P>0.05), there were significant differences between groups in left leg standing test with eyes open or closed on posttest (P<0.05).

Research conducted show that there is a positive influence of SIT on children with low level of postural stability. Its significant improvement in children with low levels of postural stability is important not only for the current functioning of those children but for their future - by protecting them from falling down and from injuries.
