Background: Passive inversion joint position sense (PIJPS) was proved to be risk factor for lateral ankle sprain (LAS) which occur commonly in female volleyball players later on matches when fatigue is present suggesting that fatigue may alter PIJPS and lead to LAS. Purpose: To investigate the effect of evertor muscles fatigue on PIJPS in volley ball female players. Study Design: One group pretest / posttest cross section design. Methods: Twenty five female volleyball players from 18-25years old were selected by convenient sampling. Formal consent was signed up. Participants were tested for PIJPS at 10 and 20 of inversion before and after induction of evertor muscles fatigue. Fatigue protocol and PIJPS assessment were performed using Biodex System 3 Pro Isokinetic dynamometer. Each test angle was tested three times then mean error (ME) was calculated. Results: There was statistical significant difference in PIJPS at 10 of inversion after evertor muscles fatigue (P<0.001). While at 20 of inversion there was no statistical significant difference (p=0.904)
