Abstract
Purpose:
Motor failure and musculoskeletal deformities, particularly among the students, can be considered as one of the most important issues in the health system nationally. Therefore, examining the relationship between physical condition and motor disabilities can play an important role in preventing and managing the postural and motor control problems.
Methods:
The present study was descriptive, relational, and predictive. Three hundred and forty students aged 7.51±0.96 years, weight 26.7±6.64 kg, height 125.98±9.10 cm, body mass 16.37±2.92 index) were selected based on the principle of availability. To assess the balance, (both static and dynamic) two tests were performed: standing and walking on wood. Posture condition components including forward head posture, round shoulder, uneven shoulder, scoliosis, kyphosis, lordosis, uneven pelvis, and knee and sole condition were also assessed. Since the normality of the data was not confirmed, Spearman test was used to analyse the data.
Results:
Descriptive results showed the prevalence of postural abnormalities in nonstructural scoliosis 55.6%, forward head 48.3%, left flat foot 71.2%, highest and hyperphysiosis 3% and knee brace 3.8% show the lowest value. The results showed the relationship between the variables as static balance with mean (5.7 ± 2.2) seconds with left shoulder prolapse with mean (.38 ±1.02) degree among 7-10 year old male students had a positive correlation (r=.155) and a negative correlation (r=.192) between the degree of sagging of the right shoulder (0.86 ± 1.5). There were not any other significant differences to report. Also dynamic balance with the average (5.45 ± 1.15) seconds and score (r=-.108) score with kyphosis angle value with average (30.34 ± 11.64) degrees and right shoulder sagging with average (0.86± 1.5) degree and score (r=.119) and cruciate knee with a mean (1.18 ± 2.11) cm had a negative correlation (r=.173) between 7-10 year old male students. There is a negative correlation between the overall balance (sum of static and dynamic balance) score and the mean points of right shoulder sagging (r=-.185) and there was a positive with the amount of left shoulder sagging (r=.146). There was not any other significant differences in other indexes
Conclusion:
The results indicated a relationship between physical condition in different parts of the body with basic static and dynamic balance skills of 7 to 10 year old boys. It can be said that balance as one of the most important basic skills in children that depends on the strength and flexibility of the body muscles with changes in the correct direction of the spine, knees and shoulders, the ratio of strength and flexibility is disturbed and possibly the basic skill of balance changes. The research proposal to correctional and motor development specialists is to pay simultaneous attention to physical condition and basic skills in correctional programs and physical development. The results of the present study indicated the relationship between right and left shoulder sagging with static balance, knee deviation inward, kyphosis angle and right shoulder prolapse with dynamic balance and right and left shoulder prolapse with total balance in children 7 to 10-year-old boys. As a result, it can be inferred that balance as one of the most important basic skills in children, which depends on the strength and flexibility of the body muscles, is associated with changes in body orientation and body position and balance can affect each other. It is not yet possible to conclude about the origin of change and to specify which the cause of change and the main factors are, and therefore more research is needed in this regard.
