Relationship Between Active Knee Extension and Active Straight Leg Raise Test Measurements

Reliability of the Active-Knee-Extension and Straight-Leg-Raise Tests in Subjects With Flexibility Deficits

“…4 Reliability studies have been done using AKE, and others have used SLR as a gold standard for other measures. [7][8][9] However, few investigations have compared the AKE and SLR in subjects with flexibility deficits. Literature shows that reduced hamstrings extensibility has a significant impact on pelvic motion.…”

Inter-tester reliability of a self-monitored active knee extension test

“…The test has been recommended as an alternative to the SLR test for providing an indication of hamstring muscle length (Cameron and Bohannon, 1993).…”

Comparing Hamstring Muscle Length Measurements of the Traditional Active Knee Extension Test and a Functional Hamstring Flexibility Test

“…A cohort study aimed to determine whether a relationship existed between the AKET and the active SLR test [19]. Unlike the current study, this study assessed both males and females, did not assess a population at high risk of hamstring injury and measurements were recorded from images taken by a camera [19].…”

“…Unlike the current study, this study assessed both males and females, did not assess a population at high risk of hamstring injury and measurements were recorded from images taken by a camera [19]. This study found a negative significant relationship between the AKET and the active SLR test (r=-0.718, p<0.001) with the common variance between the tests being slightly greater than 50% [19]. This is similar to the results of the current study as a large significant difference between measurements of the AKET and the FHFT was identified.…”
