The 30 Seconds Side Hop is used in Return to Sports (RTS) testing after lower-limb injuries, like anterior cruciate ligament (ACL) injuries and reconstruction. The goal is to test maximum single-leg hop performance under increasing fatigue and identify asymmetries between the injured and uninjured side.
Total Hop Count (Fig-1, left) is the primary outcome parameter of the 30 Seconds Side Hop. In this example, hop performance of the right and left leg are similar.
Besides numerical outcomes, a variety of qualitative outcomes, such as the pressure distribution are available for each ReGo test. Here, the pressure distribution (Fig-1, middle) during the rebound is displayed. Although the subject achieved the same number of hops, the pressure distribution shows possible asymmetries between the two sides.
In addition, the Mean Longitudinal and Transversal Rebound Point (Fig-1, right) provide insight into the hopping and landing behavior. They display the COP in anterior-posterior and medio-lateral direction, respectively. In this example, the longitudinal rebound points are similar, but the transversal rebound point on the right is more medially oriented than left.
These and the other ReGo parameters help therapists and trainers to gain a better insight into the individual performance status of their patients and to make more informed decisions in the RTS process.
