Abstract

Background: It’s well known fact that Hallux valgus (HV) alternates foot biomechanics. In different populations HV and postural stability has been studied but HV and adolescent ballet dancer has not been studied. Aim of the our study is to explore affect of HV on adolescent ballet dancers’ balance. Also we wanted to explore health related quality of life of adolescent ballet dancers with HV.

Methods: Ballets aged between 8-16 years old has been screened prospectively. The dancers divided into two groups group 1;Ballets with HV and group 2; Ballets without HV. HV diagnosis was made clinically. Two groups were compared according to balance parameters and health related quality of life (HRQOL) questionaires.

Results: Group 1 was formed with 31 participants and group 2 was formed with 24 participants. All participants in both groups were female. Mean age in group 1 was 11.6 (8-16 years old) and 12.2 (8-16 years old) in group 2. Mean first metatarsophalangeal angle was 13.4° (10°-15°) in group 2 and 19.8° (16°-25°) in HV group respectively. A statistically significant difference was found according to the nonparametric Mann Whitney U test results in the comparison of HVA (Hallux Valgus Angle) between groups. According to Spearman Rho correlation analysis, it was determined that the increase in HVA caused deterioration in the static Flamingo test. (r=0.552 p=0.019). No significant relationship was found between HRQoL questionaries and the presence of HV. (p>0,05)

Conclusions: Adolescent ballet dancers experience static balance impairment due to HV angle increase. Clinical measurement of HV and application of balance parameters made easy without need of set ups to perform evaluation with high numbers of participants in concordance with literature.
