A Study to Evaluate the effect of Fatigue on Knee Joint Proprioception and Balance in Healthy Individuals
Subscribe/Renew Journal
Aims & Objectives: A study to investigate the effect of fatigue on knee joint proprioception and balance in healthy individuals.
Materials & Methods: An observational study was conducted on 30 healthy subjects ( age 18-30 years) from Srinivas college of physiotherapy, Mangalore. Subjects was selected by simple random sampling techniques. Fatigue was induced in the subjects by cycling upto level of exceeding 60% of predicted HRmax (14-17 PRE). Subjects were tested to estimate reproduction error by using weight bearing joint position sense test at 30 0 of knee flexion , by goniometric evaluation accompanied by photographic method and the balance assessment was done on force platform with the measurement of anteroposterior, lateral CoP excursion and stability score in single limb stance, before and after fatigue protocol.
Results: After inducing fatigue,significant reproduction error was found for perception of joint position sense (t=-4.103) with significant changes were found in AP (t=3.997), lat CoP excursion (t=10.949) and stability score (t=11.785) at p>0.05.
Conclusion: A study revealed that moderate exercises can reduce proprioception which affects the neuromuscular control of joint making individual more suspectible to injury.
