Abstract

Postural control and DYNAMIC BALANCE are essential in activities of daily living and for optimal performance in sport activity. The purpose of this study was to determine if excessive and normal KNEE Q ANGLE influence measure of DYNAMIC BALANCE in FEMALE ATHLETEs. Twenty females athlete with right dominant side participated in this study. 10 subjects with excessive KNEE Q ANGLE (Q>18), (age= 21.20±1.4 years, height= 163.5±4.5 cm, mass= 61±8.02 kg, Q angle= 19.85±1.2 degree) and 10 subjects with normal KNEE Q ANGLE (13<Q<18), (age= 22.10±1.1 years, height= 165.5±6.02 cm, mass= 59.9±10.1kg, Q angle= 15.35±1.4 degree) volunteered. The subject’s demography, medical and athletic backgrounds, exercise programs and their injury reputation were collected by special forms. The subjects reported no history of fracture in lower extremity or history of neurological or vestibular impairments. The rest of the information was measured through quantitative measuring and examinations so that measuring of Q angle by standard drawing method and universal goniometry. The star excursion balance test was used to measure DYNAMIC BALANCE, which was reported as the reach distance (cm) in each of the 8 directions tested. The average of 3 trials of each measure was calculated and normalized to the subject’s leg length. The mean of reach distance in 8 directions in females with abnormal Q angle (Q>18) were less than females with normal Q angle. We found significant differences in anteromedial, poster lateral and anterior directions between two groups. Our results suggest that postural stability is affected by knee alignment under dynamic conditions.
