Reebok Movement Screens
Purpose : The In-Line Lunge is used to assess mobility around the pelvis in relation to core stability; also balance and stability of the entire kinetic chain. Lunging requires your client to open up at the hips, moving in opposite directions with each leg, while maintaining core stability and balance. The in line stance (with one leg literally in front of the other) and relatively short stride lunge challenges the balance and stability even more.
Description : The client stands with feet together, arms up overhead, either with or without holding a dowel behind head. The client steps forward, landing one foot directly in front of the other. The stride length should only be long enough for the rear knee to come right behind the front heel as both knees bend. The feet should be along the same line and pointing straight throughout the movement. The lunge is performed three times on each side in a slow controlled fashion. Score the right side when the right leg is in front, and score the left side when the left leg is in front. If one repetition out of three is completed successfully then a 2 is given. The lowest score on a given side is indicated as the total test score.
Movement Screen Criteria to Score a 2
  • Balance maintained
  • Feet remain on the line
  • Knee touches line behind heel of front foot
  • Minimal to no upper body movement
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
Difficulty in staying still in the core -leans forwardMay need more strength in the core as client opens up at the pelvis (essentially training the movement pattern).
Increase in the lumbar curveHip flexors of the rear leg may need stretching
Rear leg keeps externally rotating or difficulty in maintaining the in line positionExternal rotators and lateral muscles of the whole kinetic chain may need stretching
