Abstract
The present study examines the effect of vestibular disturbances on the angles of the lower joints during walking in active children. The present study was conducted on 30 boys with the age range of 7 to 11 years in Tehran, who were selected for the research by available sampling method. Subjects walked a 12-meter track in the laboratory under four different sensory conditions (walking with eyes open, walking with eyes closed, walking with eyes open with vestibular perturbation, and walking with eyes closed with vestibular perturbation). Joint angles were recorded through vicon cameras and markers, and hip, hip, knee, and ankle joint angles were extracted. Data analysis was done using ANOVA with repeated measures with significance level (p≤0.05). The results showed that in Ankle joints (sagittal P=0.001, frontal P=0.000, horizontal P=0.000), knee (sagittal P=0.043, frontal P=0.002, horizontal P=0.000), thigh (sagittal P=0.000, frontal P=0.000, horizontal P=0.000) =), and pelvis (sagittal P=0.000, frontal P=0.047, horizontal P=0.000), a significant effect was observed. However, the obtained results can consider the need to pay attention to strengthening this sense in children who face less risks. Also, the results showed that the removal of visual inputs in walking without disturbance does not cause significant changes in joint angles. Therefore, it can be concluded that vestibular disturbances can change the range of motion by changing the joint angles and the walking pattern, which shows the compensatory mechanism of maintaining balance. Finally, changes in range of motion are a risk factor in imbalance that leads to injury.
