Reebok Movement Screens
Purpose : The Active Straight Leg Raise is used to assess active hamstring flexibility, in relation to core stability. This screen is performed actively (instead of passive flexibility assessment) in order to see the true available range of motion your client has during life and sport. For example, it does not help the client to have flexible hamstrings if he cannot use them without straining the stability of the core to get that range of motion.
Description : Client lies supine with both legs straight and neutral and a natural curve in the low back. The client lifts up one leg, keeping that ankle relaxed and the leg straight. The opposite thigh should remain still and straight. Normal range of motion is approximately 80-90 degrees. Perform 3 reps on each side, observing when legs or pelvis are no longer still and stable. If one of the repetitions is done correctly, then a 2 is scored. The lowest score on a given side is indicated as the total test score.
Movement Screen Criteria to Score a 2
  • Pelvis stays still
  • Range of motion = 80-90 degrees without either leg moving
Scoring Options
2 No action required - your client meets the observation requirements
1 If any of the preceeding criteria does not occur a one is given.
0 A zero is given if pain is associated with any portion of this screen. It is recommended that a thorough evaluation of the painful area be performed by a medical professional.
Observations and Possible Corrective Exercises if Score is 1 :
ObservationsCommentsSuggested Exercises
If the client has less than 80-90 degrees hip flexion and hamstrings are restricting his range of motionMany need to stretch hamstrings
If the client reports a stretch in the calf muscles, then put the calf into plantarflexion, putting the calves in slack.If the range of motion improves, the restriction could be due to tight calves more than tight hamstrings.
Non-moving thigh comes up off the floor and the pelvis tilts posteriorlyMay need to stretch the hip flexors on the opposite side
General inability to keep the pelvis still as one of the legs is movingMay need some basic core stability exercises
