Effect of Core Stability Training on Knee Proprioception after Anterior Cruciate Ligament Reconstruction

Abstract
Background: Decreased core stability reduce activity participation of athlete. Deficits of core stability is neuromus-cular risk factor for anterior cruciate ligament (ACL) injury.
Purpose: This study was conducted to study the effect of core stability training (CST) on knee proprioception and function after ACL reconstruction.
Methods: Thirty patients of both gender after ACL reconstruction. Their age ranged from 20-30 years. All patients were referred by the orthopedic surgeon who was responsible for diagnosis and surgery based on clinical and radiological examination. They were randomly assigned into 2 groups group A included 15 patients received standard ACL rehabil-itation protocol and group B included 15 patients received CST in conjugation with standard ACL rehabilitation protocol. Three sessions per week for 8 weeks. The study was conducted in the duration from August 2016 till August 2017 at a private orthopedic and arthroscopic center.
Evaluation: The digital inclinometer has been used to assess knee proprioception (joint position sense) after ACL reconstruction.
Results: Showed that both standard ACL rehabilitation protocol (group A) and CST in conjugation with standard ACL rehabilitation protocol (group B) were effective in improving the knee proprioception.
Conclusion: There was no significant difference in knee proprioception between standard rehabilitation protocol with or without CST, however there was clinical difference and high percent of improvement in adding CST to standard rehabilitation protocol.
