Conditions
Interventions
Children in intervention group will be trained by Whole-
Body Vibrator (EX1000) with frequency 50 Hz. The whole-
body vibrator will be set in oscillatory type and amplitude 4 mm. The duration of training is 5 minutes/set,
3 sets/day,
3 days/week for 6 weeks. Children will start in squat position with barefoot (Figure 3) for 1 minutes. Then,
Children will stand with single leg 5 minutes/set. Children will be allowed to rest for at least 3 minutes between each set training of the whole body vibration training. ,Children in control group
