Markers will be placed along a wall at a 90-90 hip flexed position and at the feet when feet are placed shoulder-width apart. The patient will be instructed to perform 10 rapid, consecutive tuck jumps. The tuck jump assessment will be filmed from both a front and lateral view. The tester will identify if any of the 10 technique flaws listed below are observed and will score accordingly.
Possible technique flaws:
- Lower extremity valgus at landing
- Foot placement not shoulder width apart
- Thighs not equal side-to-side (during flight)
- Excessive landing contact noise (lateral view)
- Foot placement not parallel (front to back) (lateral view)
- Thighs do not reach parallel (peak of jump) (lateral view)
- Foot contact timing not equal
- Does not land in same footprint (excessive in-flight motion)
- Pause between jumps
- Technique declines prior to completion of 10 jumps
The patient will start with a score of 10. Subtract 1 point for each technique flaw observed. Subtract 2 points if patient is unable to complete 10 consecutive jumps. A score of of 5 or more is a passing score.
