Finally, inverse significant correlation was found between total level among the patients in knowledge, neck pain & disability in study group at post intervention (r=-0.53 p=0. 003). Conclusion: Application of enhanced recovery protocol for patients undergoing thyroidectomy had a statistically significant positive effect on alleviating neck pain, functional disability, and postoperative complications.
