title: Mild hallux valgus angle affects single-limb postural stability in asymptomatic subjects.
abstract: BACKGROUND
  Single-limb postural stability is a key component of lower extremity functional status. Factors affecting postural stability should be well defined to prevent injuries.
  
  
  OBJECTIVE
  The aim of this study was to investigate the effect of the hallux valgus angle on postural stability in asymptomatic subjects.
  
  
  METHODS
  A total of 19 subjects were included in the study. The hallux valgus angle and postural stability were assessed. Participants were assigned to two groups according to whether the hallux valgus angle was pathological or not. A hallux valgus angle greater than 15 degrees was accepted as pathological. The relationship between the hallux valgus angle and postural stability, and the differences in postural stability scores between the two groups were analyzed. Postural stability was assessed with a stabilometer. The test was performed with the eyes open.
  
  
  RESULTS
  We found a significant correlation between the hallux valgus angle and mediolateral and overall stability index (r= 0.484, p= 0.036; r = 0.463, p= 0.046 respectively). Subjects with a pathological mild hallux valgus angle had greater stability index scores than normal subjects (p< 0.05).
  
  
  CONCLUSIONS
  A mild hallux valgus angle has negative effects on postural stability as a forefoot deformity. This deformity should be taken into account for injury prevention strategies in pain-free younger adults.
