Instructions
Preparation
Lie supine floor or mat with board (approximately 2 x 6 inch or 5 x 15 cm) under knees. Place arms down to sides.
Execution
Raise leg with knee completely extended and ankle dorsiflexed. Repeat on opposite leg.
Measurement
Dowel or plumb line is placed next to inside ankle and allowed to dangle vertically between legs off floor. Record scores for both sides. Position of dowel relative to anatomic landmarks is noted:
- Anterior superior iliac spine (ASIS)
- front bony surface of hip bone on each side
- Mid-thigh
- Joint line of kne
Assesses
- Lower Quadrant Symmetry
- Joint ROM and Flexibility
- Upper leg
- Hip Flexion mobility
- Hamstrings
- Lower leg
- Upper leg
- Pelvic and core stability
- Active Force
Scoring
Score | Dowel Position |
---|---|
3 | ASIS to Mid-thigh |
2 | Mid-thigh to Joint Line |
1 | Below joint line |
0 | Pain |
If pain is felt during this movement, score 0 and refer out for orthopedic evaluation.
Comments
Opposite knee should remain in contact with board. Lower back and head should remain on floor.
This test is part of the Functional Movement Screening (FMS). Score of 2 or less, discontinue activities until corrected:
- Heavy closed-chain loaded activities
- Running
- Plyometrics
Interestingly, higher scoring ALSLR has been correlated to poorer agility and leg power test scores (Lockie 2015)
