This pattern not only identifies the active mobility of the flexed hip, but includes the
initial and continuous core stability within the pattern, as well as the available hip extension of the
alternate hip.
This is not so much a test of hip flexion on one side, as it is an appraisal of the ability
to separate the lower extremities in an unloaded position. This movement is often lost when flexibility of multi-articular muscles is compromised.
