Introduction: Different factors have been put forward as positive or negative influences on the knee joint position sense; however, the effects of hamstring flexibility have not been the object of extensive research. Objective: To study the influence of hamstring flexibility on the knee joint position sense. Methods: The knee joint position sense of 31 adults was tested actively to extension to a 45° range of knee flexion, in both the dominant and non-dominant limb. Hamstring flexibility was assessed through the sit and reach test. Based on the results, participants were divided into high and low flexibility categories. Intergroup analysis and tests of the association between flexibility and repositioning errors were performed. Results: No significant differences were found between the two categories of flexibility and repositioning accuracy. Similarly, no significant associations were found between flexibility and repositioning errors (p>0.05). Conclusions: These results suggest that hamstring flexibility does not affect knee repositioning accuracy, implying that both lower and higher flexibility do not impair the knee joint position sense.
