proprioceptive testing is more commonly used in clinical settings to
evaluate injured athletes to return to activity. Muscle fatigue
produces neuromuscular deficiency within the muscle, thus predispose a
joint to injury and decrease the athletic performance. A finding of
previous studies shows contradictory findings of effect of muscle
fatigue on proprioception and balance.
Aims. A study to investigate the effect of fatigue on knee joint proprioception and balance in healthy individuals.
and 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 up to level of exceeding
60% of predicted maximal heart rate (HRmax). Subjects were tested to
estimate reproduction error by using weight bearing joint position
sense test at 300 of knee flexion, by goniometric evaluation
accompanied by photographic method and the balance assessment was done
on force platform with the measurement of anteroposterior (AP), lateral
center of pressure (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
fatigue, proprioception, balance, dynamic stabilityFull
