BACKGROUND: Changes in postural stability may be a reason for injuries in individuals who have altered musculoskeletal alignment. Q angle (QA) has shown to be a predictor for lower extremity injuries. However, the relationship between balance and QA has not been investigated in young adults.
OBJECTIVE: The aim of the study was to investigate the relationship between QA and balance in young adults.
METHODS: Ninety participants performed the single leg stance test (SLST) and Star Excursion Balance Test (SEBT) to assess static and dynamic balance, respectively. QA was measured using a manual goniometer. Participants were divided into low, normal and high QA groups.
RESULTS: The relationship between SLST and QA was not statistically significant in both eyes opened and closed condition (r=-0.030, p= 0.782; r= 0.031, p= 0.774; respectively). SLST scores did not differ among the three groups in both eyes opened and closed condition (p= 0.781, p= 0.790; respectively). QA significantly correlated with lateral, posterolateral directions and sum score of SEBT (r= 0.240, p= 0.023; r= 0.269, p= 0.010; r= 0.210, p= 0.047). The comparisons among the low, normal and high Q angle groups' SEBT scores showed that balance performance in lateral direction was poorer in low QA group (p= 0.027).
CONCLUSIONS: The results of the study showed that QA and dynamic balance have a significant relationship. To reduce musculoskeletal injury risk, the dynamic balance should be assessed in young adults who have lower QA.
