Physical Therapy Aide Training Practice Test

The exercise being tested is defined by the range of motion the quadriceps works through. A long arc quadriceps workout uses a larger knee ROM, starting with the knee in a flexed position and moving through a wide arc toward full extension. Because the movement is extended across more of the knee’s range, you often see the leg “kicked off the table” as it straightens and the lower leg moves away from the supporting surface. This helps strengthen the quadriceps across a greater portion of its action, which is useful when you want the muscle to control the knee through a larger portion of its movement. Other options don’t fit this description. Windshield wipers isn’t a quad-length arc knee extension exercise. A short arc quadriceps targets a smaller portion of the ROM, not the long arc. An arm bike uses the upper body, not the quadriceps.
