Relation Between Near Point of Convergence and Postural Stability in Subjects With Non Specific Cervical Pain

Overview

A correlation study was conducted to correlate between the convergence insufficiency and postural stability at three different cervical positions in patients with non-specific cervical pain.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Cross-Sectional
  • Study Primary Completion Date: January 20, 2019

Detailed Description

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).
