Purpose : This study was performed to find out the influence of the change on proprioception and coordination of the lower limb by experimentally induced paraspinal muscle fatigue, Methods : Twelve subjects(6 males, 6 females) with no history low back and lower limbs problem volunteered for this study. Subjects were pre-tested proprioception and coordination using the MR-FSS(Mornitored Rehab Functional Squat System). And then the subjects performed isometric paraspinal muscles contraction for induced muscle fatigue. Muscle fatigue was defined surface EMG(MP 150). After isometric contraction, the subjects were post-tested using the MR-FSS. Results : In comparison of coordination, deviation of concentric coordination was increased(from $0.50{pm}0.13cm$ to $0.67{pm}0.21$)(p<0.05) and deviation of eccentric coordination was also increased(from $0.51{pm}0.15cm$ to $0.70{pm}0.26cm$)(p<0.05). And deviation movement of proprioceptive test was increased(from $4.98{pm}1.80cm$ to $5.69{pm}1.98cm$), but there was no significant different(p>0.05). Conclusion : Fatigue of paraspinal muscles was decreased concentric and eccentric coordination of the lower limb.
