To Compare the Effect and Sustainability of a Course Corrective Games with Selected ‎Corrective Exercise on 10-12 Aged Boys with Hyper Thoracic Kyphosis

Thoracic hyperkyphosis is one of the common anomalies in children in recent years. In addition to corrective exercise, corrective games are one of the correctional methods which have been used to prevent and correct functional anomalies among children. Unlike corrective exercise, in corrective games method, correctional goals apply with prevention and correction purpose in the game shape and format The present study aimed to compare the effect and sustainability of a course corrective games with selected corrective exercise on 10-12 aged boys with thoracic hyperkyphosis.Ninety boys with age average (11.20±0.80 years), height average (140.78±5.91 cm), and weight average (39.69±4.75 kg) were randomly divided into corrective games, selected corrective exercise and control group. Subject in experimental groups performed their related corrective games and corrective exercises for 8 weeks and 3 sessions every week. Each session lasted for 30-60 minutes. During this time the control group did their normal daily activity. The kyphosis angle required to enter to the study was considered greater than 40 degrees. This angle was measured by a flexible ruler. Data were recorded at the beginning of the study as a pre-test, at the end of the 8 weeks’ exercises as a post-test and 8 weeks after the completion of the study as a second post-test level.The finding of the repeated measure ANOVA test indicated a significant difference in kyphosis angle at the pre-test level (45.62±2.40) versus the post-test level (42.46±2.24), and in follow-up level (42.42±2.09) in the corrective games group, and the pre-test level (45.81±2.59) versus the post-test level (42.26±2.36) and in the follow-up level (42.52±2.27) in the selected corrective exercise group (P≤0.05). Moreover, there was no significant difference in the kyphosis angel in the control group, at the pre-test level (44.93±1.59) versus the post-test level (45.26±1.79) and in the follow-up level (45.26±1.84) (P>0.05). The obtained effect size was 0.85 in the corrective games group, 0.81 in the selected corrective exercise group, and 0.08 in the control group, which shows the high effectiveness of present study protocols in experimental groups. Also, the results of the ANCOVA test indicated a significant difference in thoracic kyphosis angle between 3 groups in the study at the post-test and the follow-up levels (P≤0.05). Therefore, in order to clarify this difference, the Bonferroni post-hoc test was used. The finding of this test indicated a non-significant difference in thoracic kyphosis angle between corrective games and selected corrective exercise groups in the post-test and follow-up levels (P>0.05). The observed difference was related to the corrective games and selected corrective exercise kyphosis angle difference with control groups at mentioned levels (P≤0.05).The corrective games and the selected corrective exercise have a positive and similar effect with exercise effects sustainability on thoracic kyphosis reduction. Therefore, performing 8 weeks’ corrective games besides selected corrective exercise has a considerable and sustainable effect on thoracic hyperkyphosis angle in 10-12 aged boys and using corrective games as an autonomous method recommended to thoracic hyperkyphosis correction in 10-12 years old boys.
