Influence of Acute Back Muscle Fatigue on Repositioning Accuracy of the Knee Joint In healthy subjects
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 1
Abstract
Background: The proprioceptive system is responsible for the body coordination and stability; it is a major component of function and performance in the functional activity. Purpose: To investigate the effect of acute back muscle fatigue on repositioning accuracy of the knee joint in healthy subjects. Design: A pre test post test design Methods: 100 healthy subjects of both genders aging from 18 – 22 years and body mass index from 20-25 kg/ m² participated in this study. Active angle repositioning test was used to assess the proprioceptive accuracy of the non-dominant knee joint at 45 degree knee flexion by Biodex system 3 pro isokinetic dynamometer pre and immediately after back muscle fatigue protocol used by biodex system. Results: The statistical analysis revealed that repositioning accuracy of the knee joint was significantly decreased (p<0.05) after fatigue protocol of the back muscle Conclusion: acute back muscle fatigue reduces repositioning accuracy of the knee joint
