Abstract

The purpose of this study is to determine the effects of eccentric hamstring fatigue on the ability to accurately reproduce different knee joint angles. Thirty-one males and 29 females, 18-40 years old, were randomly assigned to treatment and control groups. Using the Biodex®, proprioceptive pre-test and post-test measurements were taken having the blindfolded participant replicate predetermined angles of 25°, 45°, and 65°. The control group underwent a passive movement protocol and the treatment underwent a fatigue protocol. Data Analysis was performed using 2-tailed t-test comparing the means of pre-test and post-test angle accuracy measurements for the control and treatment groups. Neither group showed a statistically significant difference in these measurements (p<0.05). Analysis of variance (ANOVA) was completed comparing pretest and posttest accuracy within angle category, gender, limb, angle order effect, and group. Results indicated statistical significance (p=0.002) in the angle category at 25° within the control group only.
