ASSESSMENTS: The key to the perfect rehab program! Overhead Squat Rx (flexercise example) Single Leg Raise Assessment The Active Straight Leg Raise test is used to assess active hamstring and gastroc/soleus flexibility, while maintaining a stable pelvis.. The ability to perform the Active Straight Leg Raise test requires functional hamstring flexibility. This flexibility is the true flexibility an athlete has available during training and competition, as opposed to passive flexibility, which is most often assessed. The athlete is also required to demonstrate adequate passive iliopsoas flexibility of the opposite leg as well as lower abdominal stability. Poor performance during this test can be the result of several factors. First, the athlete may have poor functional hamstring flexibility. Secondly, inadequate passive mobility of the opposite hip may be the result of iliopsoas tightness associated with an anterior tilted pelvis. If this limitation is gross, true active hamstring flexibility will not be realized. A combination of both these factors will demonstrate an athlete's relative bilateral, asymmetric hip mobility. This is similar to the relative hip mobility revealed by the Hurdle Step, however, this test is more specific to the limitations imposed by the muscles of the hamstrings and the iliopsoas. In Line Lunge Assessment The In-Line Lunge is used to assess bilateral mobility and stability, as well as ankle and knee stability. The ability to perform the In-Line Lunge test requires stance leg stability of the ankle, knee, and hip as well as closed-kinetic chain hip abduction. The In-Line Lunge also requires step leg mobility of the hip adduction and ankle dorsi-flexion. The athlete must also display adequate balance during this test. Poor performance of this test can be the result of several factors. First of which is inadequate hip mobility of either the stance or step leg. Secondly, the stance leg knee or ankle may not have the required stability as the lunge is performed. Thirdly, an imbalance may be present between adductor weakness and abductor tightness about one or more hips. Finally, tightness of the rectus femoris on the stance leg may be the cause for poor performance. Rotation Assessment The Rotational Stability test is used to assess multi-planar stability while a combined upper and lower extremity motion is performed. The ability to perform the Rotational Stability test requires asymmetric trunk stability in both sagittal and transverse planes during asymmetric upper and lower extremity movement. Many functional activities in sport require the trunk stabilizers to transfer force asymmetrically from the lower extremities to the upper extremities and vice versa. Running and accelerating out of a down stance in track and football are common examples of this type of energy transfer. If the trunk does not have adequate stability during these activities, kinetic energy will be dispersed, leading to poor performance as well as increased potential for micro-traumatic injury. In-Line Hurdle Assessment The Hurdle Step is used to assess bilateral mobility and stability of the hips, knees, and ankles. The ability to perform the Hurdle Step test requires both stance leg stability of the ankle, knee, and hip as well as maximal closed-kinetic chain extension of the hip. The Hurdle Step also requires leg open-kinetic chain dorsi-flexion of the ankle and flexion of the knee and hip. The athlete must also display adequate single leg stance balance during this test. Poor performance of this test can be the result of several factors. It may simply be due to poor stability of the stance leg or poor mobility of the step leg. However, imposing maximal hip flexion of one leg while maintaining apparent hip extension of the opposite leg requires the athlete to demonstrate relative, asymmetric hip mobility.
