Power Testing: Single-Legged Timed Side Hop Function Test

The Single-Legged Timed Side Hop Function Test is a physical performance test used to assess lower extremity function and dynamic balance. The test assesses several aspects of lower extremity function, including power, speed, coordination, and balance. It can also be used to track progress over time and to determine when an individual is ready to return to sport or other physical activities.

To perform the Single-Legged Timed Side Hop Function Test, follow these steps:

1. If there is access to the MAT, lay this out on a flat piece of floor. Alternatively, take either a cone or marker to create three different landing areas. 
2. Have the client stand on one leg, with the other foot raised off the ground and held behind the body.
3. Instruct the client medially from one box, to the other and then next and back to where the client started. Ensure they stay on the same foot. This is considered one repetition.
4. Using the Mearsurz app timer, press play when the client commences the test and stop at the conclusion. 
5. Following an adequate rest period, have the client repeat this test if need be. Then, complete the same procedure on the opposite leg.
6. Record the best time on each side as the client’s score.

It is important to ensure that the individual maintains proper form throughout the test, including a stable trunk and knee alignment, and that the hopping foot fully clears the cone or object with each repetition. If necessary, adjust the distance of the lateral hop or the duration of the test based on the individual's ability and goals.

Normative data for the Single-Legged Timed Side Hop Function Test varies depending on age, sex, and activity level. However, one study published in the Journal of Athletic Training in 2018 provided normative data for college-aged individuals.

 It is recommended that any individual being tested should be compared to their own previous scores to track progress and determine improvement, rather than solely relying on normative data.
