The purpose of this study was to examine intratester reliability of a test designed to measure tightness in the hamstring muscles. [] Key Method The test measures the angle of knee flexion with a pendulum goniometer after active knee extension with the hip stabilized at 90 degrees flexion. The angle of knee flexion represents hamstring tightness. After an instruction session for the subjects, the hamstring muscle tightness of both extremities of 15 men was measured during test and retest sessions. The…

Passive knee extension test to measure hamstring muscle tightness
TLDR
It is concluded that the passive knee extension test is a simple and reliable method, and the associated pelvic motion is minimal.

TLDR
Examination of the intratester reliability of a test designed to measure tightness in the rectus femoris muscle found it to be an objective and reliable tool for measuring RFM tightness.
The active knee extension test and Slump test in subjects with perceived hamstring tightness
Reliability of Measured Popliteal Angle by Traditional and Stabilized Active-Knee-Extension Test
TLDR
The results show the traditional and stabilized AKE test to be highly reliable, with test-retest reliability, however, the stabilized Ake test represented less variation and more stabilization than the traditional AKE Test.
Mechanical behaviour of hamstring muscles in low-back pain patients and control subjects.
The Cut-off Values for the Diagnosis of Hamstring Shortness and Related Factors
TLDR
The knee extension angles of healthy young people seem to be lower than the results currently reported in the literature, and a significant positive correlation was observed between knee extension angle and isokinetic knee extensor muscle strength.
A new hamstring test to complement the common clinical examination before return to sport after injury
TLDR
The new test showed high reliability and construct validity and seems to be sensitive enough to detect differences both in active flexibility and in insecurity after acute hamstring strains at a point in time when the commonly used clinical examination fails to reveal injury signs.
Effect of hamstring flexibility on isometric knee flexion angle–torque relationship
TLDR
The angle–torque relationship was shifted to the left in less flexible hamstrings such that knee flexion torque was increased at short muscle lengths and decreased at long muscle lengths when compared with more flexible hamstrings.
Interrater Reliability of the Active-Knee-Extension Test for Hamstring Length in School-Aged Children
TLDR
The results suggest that the AKET, when used with the stabilizing apparatus, demonstrates good interrater reliability for children aged 10 to 13 years.

TLDR
There is a correlation between the results of two types of testing hamstring muscle length including SRL and AKE tests among patients with LBP having tightness in their hamstring muscle.

Relative contribution of the back and hamstring muscles in the performance of the toe-touch test after selected extensibility exercises.
TLDR
Results indicate that the extensibility of the hamstring muscles appeared to be one of the main contributing factors to hip joint flexion, and since the warm-up did not affect the flexibility of the back, one might conclude that the back made no increased contribution to hip Joint Flexion, as measured in this study.
The influence of isometric exercise and passive stretch on hip joint motion.
TLDR
Results of the mean differences in pelvifemoral angle measurements indicated that both treatment groups significantly increased their range of passive hip flexion with the knee extended when compared to the control group.
Cinematographic analysis of the passive straight-leg-raising test for hamstring muscle length.
TLDR
The findings suggest that pelvic stabilization is difficult and that methods used to indicate hamstring length should take pelvic rotation into account.
Ipsilateral and contralateral effects of proprioceptive neuromuscular facilitation techniques on hip motion and electromyographic activity.
TLDR
Comparison of pretest and posttest measurements of the angle of straight leg raising of both lower extremities indicated that the increase in range of motion of the right lower extremity in subjects in the contract-relax group was significantly greater than that in the hold- Relax and control groups.
Effect of Fluori-Methane spray on passive hip flexion.
TLDR
The results of the study showed that the experimental group, which received application of Fluori-Methane spray and static passive stretch, did significantly increase the range of passive hip flexion over that of the control group,Which received onlystatic passive stretch.

TLDR
It was found that a positive straight-leg-raising test has minimal value in differentiating a patient with herniated disc from other patients with love back pain and sciatica.
Electromyographic investigation of muscle stretching techniques.
TLDR
Rank orderings of minimum pain and maximum perceived stretch effectiveness were significantly related with one another, and with decreasing EMG activity, but not with range of motion.
