About this study

A correlational study was conducted on eighty (male and female) subjects aged between 30-40 years old, presented with chronic NSCP persisted for six months or more, with neck disability index score (NDI) ≥10%, and can possess at least 45° of left and right cervical rotation participated in the study. Convergence insufficiency was evaluated by the near point of conversion (NPOC) rule and postural instability was examined by the Biodex balance system. RESULTS: There was significant positive correlation between (NPOC) and anteroposterior stability index (APSI) at the three cervical positions; neutral, 45° right torsion and 45° left torsion (P>0.05).
