Abstract Background: Subjects with non-specific cervical pain (NSCP) experience sensorimotor deficits thought to be due to abnormal cervical afferent input. Convergence insufficiency (CI) and postural instability may be features in (NSCP) and finding a relation between them might help to guide assessment and management. methods: Eighty subjects (male and female) with chronic non-specific cervical pain; age ranged from 30 to 40 years with neck disability index score (NDI) {u2265}10%, can possess not less than 45{u00B0} of left and right cervical rotation and cervical pain persisted for 6 months or more.Convergence insufficiency evaluated by the near point of conversion (NPOC) rule and postural instability evaluated by Biodex balance system. results: There was significant positive correlation between (NPOC) and antro-posterior stability index (APSI) at neutral position, 45{u00B0} right torsion and 45{u00B0} left torsion was (r = 0.82, p = 0.0001; r = 0.84, p = 0.0001; r = 0.87, p = 0.0001) respectively. Since, the correlation between NPOC and medio-lateral stability index (MLSI) at neutral position, 45{u00B0} right torsion and 45{u00B0} left torsion was (r = 0.85, p = 0.0001; r = 0.73, p = 0.0001; r = 0.82, p = 0.0001) respectively. conclusion: There was significant strong positive correlation between (NPOC) and (APSI) and also, between (NPOC) and (MLSI) in neutral position and when subjects were placed in right or left torsion |
