Abstract
The purpose of this study was to investigate the effect of different head positions on postural stability in normal subjects.
Subjects: One hundred normal subjects (54 females and 46 males), their age ranged from 20 to 35 years, and with BMI "Body Mass Index" ranged from 20.04 to 24.98Kg/m2 were assessed for postural stability from five different head positions.
Methods: Subjects were in one group and assessed as one shot for postural stability by BIODEX balance system from five different head positions (neutral position, 20º of head flexion, 40º of head flexion, 20º of head extension, and 30º of head extension), each test was applied for twenty seconds with feet supported on platform and head stabilized by a collar in each certain degree which measured by CROM device.
Results: There was statistical significant difference in the mean values of postural stability index among the five different head positions used in this study.
Conclusion: Different head positions have great impact on postural stability which might be valuable in assessment and rehabilitation for patients with cervical disorders and balance disturbance.
