Movement Screens (FMS): Inline Lunge

Purpose: The inline lunge movement mimics lower-extremity deceleration and direction changes produced in sport, exercise, and daily activity. This test evaluates lower-extremity mobility and stability, as well as flexibility of the back and hamstrings. 

Equipment: Screening Kit


  • Record the length of the client's tibia, measuring it from the floor to the top center of the tibia, and mark the appropriate site on the board.
  • Instruct the client to place the toe of their back foot at the start line of the board. 
  • Instruct the client put their heel of the front foot at the appropriate mark on the board. 
  • Place the dowel behind his/her back, touching the back of their head, thoracic spine and sacrum. 
  • Have the client’s hand opposite the front foot, grasp the dowel at the cervical spine, and the opposite hand grasping at the lumbar spine. 
  • Instruct the client to lower their back knee to touch the board behind the heel of the front foot, and return to the starting position. 
  • The dowel must maintain its perpendicular position throughout both the downward and upward movements.
  • Perform test on each side up to 3 times and record best score.
