An intervention study of postural control in children : effects of Tai Chi like exercises on postural control in girls and boys (English)
Abstract [sv]

Syfte

Tidigare forskning har visat att Tai Chi träning förbättrar balansen hos äldre. Syftet med denna studie var att undersöka om barns balans påverkades av träning som utfördes i ett långsamt tempo liknande Tai Chi träning.

Studien syftade också till att utreda om det förelåg någon skillnad i balans mellan pojkar och flickor och om något av könen tog till sig träningen bättre. Studien syftade även till att undersöka hur balansen påverkades då barnen utförde olika kognitiva uppgifter.

Metod

Studien fullföljdes av 41 barn i åldern 9-10 år. En interventionsgrupp, 19 barn tränade Tai Chi liknande rörelser dagligen under åtta veckor och denna jämfördes med en kontrollgrupp, 22 barn som inte fick denna träning.

Balansövningar utfördes på en kraftplatta samt på en metallprofil. Från övningarna på kraftplattan mättes standardavvikelse och amplitud av tryckcentrums mediolaterala och anterioposteriora förflyttning. Från övningarna på metallprofilen mättes antalet nedtramp.

Resultat

Många parametrar mättes men endast en uppvisade en signifikant träningseffekt. Pojkarna minskade standardavvikelsen på tryckcentrums mediolaterala förflyttning vid stående med öppna ögon.

Studien uppmätte vissa skillnader i balans mellan pojkar och flickor.

Mätningar av tryckcentrums förflyttning då barnen utförde olika uppgifter uppmätte en signifikant skillnad vid stående med öppna ögon jämfört med stående då ögonen var stängda (med eller utan utförande av en samtida kognitiv uppgift).

Övningarna på metallskenan förbättrades lika mycket i tränings- som kontrollgrupp.

Slutsats

Studien ger indikationer att träningsformen i viss utsträckning var effektiv då daglig träning under åtta veckor gav signifikant förbättring i en av de testade parametrarna.

Dessa fynd är i linje med de fåtal studier som finns på träning av balans hos barn.

 

Abstract [en]

Aim.

Previous studies have shown that Tai Chi exercises improve postural control in elderly people. The primary aim of this study was to investigate if similar Thai Chi like training affects postural control in children. Secondary aims of the study was 1) to investigate if any such effects from training differs between boys and girls and 2) to investigate whether performing a cognitive task during balance testing had any effect on postural control in these children.

Method.

In the balance tests, different tasks were performed on a force plate and on a metal profile. From the tasks performed on the force plate, the standard deviations and amplitudes of the mediolateral and anterioposterior displacements of center of pressure were measured. From the tasks performed on the metal profile, the number of clampdowns were counted.

The study was conducted over an eight week period with 41 children in the ages 9-10 years old. The children were divided into two groups; children in the training group (n=19) who participated in Tai Chi like training every day, and children in the control group (n=22) who did not participate in this training.

Results.

The study also showed some differences in postural control between boys and girls.

When comparing the displacement in center of pressure between different two-legged tasks performed on the force plate, significantly less displacement was found in the task involving standing with open eyes compared to all tasks involving standing with closed eyes (with or without a concurrent cognitive task).

The number of clampdowns from the metal profile were reduced after the training period, to a similar extent in the control and the training groups.

Several different aspects of the postural control were measured in the study. Only one of these improved significantly with training. Boys in the intervention group showed a decrease in the standard deviation of the mediolateral displacement of the center of pressure when standing with open eyes.

Conclusion.

These results are also consistent with similar studies on postural control among children.

This study indicates that slow motion training, similar to Tai Chi, has a small but positive effect on postural control, for boys 9-10 year old, when conducted every day over an eight week period, as one of the tested parameters shows an improvement.
