Your patient is lying supine and you are strengthening the iliopsoas on the (R) using manual resistance.The main reason you would want to place the patient's (L) hip and knee in flexion (foot planted on the table) is to:
A)Stretch the erector spinae muscles in the lumbar region of the back.
B)Improve the mechanical efficiency of the iliopsoas on the (R).
C)Stabilize the pelvis in a neutral to posteriorly rotated position to lessen the possibility of an anterior pelvic tilt occurring, placing stress on the low back.
D)Place the pelvis in a slight anterior tilt so the trunk is more stable and the iliopsoas can generate greater tension.

Placing the patient's (L) hip and knee in flexion with the foot planted on the table stabilizes the pelvis in a neutral to posteriorly rotated position. This helps to prevent an anterior pelvic tilt, which can place stress on the low back. This position also improves the mechanical efficiency of the iliopsoas on the (R) by allowing it to generate greater tension with less compensatory movements from other muscles. While stretching the erector spinae muscles is important, it is not the main reason for placing the patient in this position. A slight anterior tilt of the pelvis can create instability and is not ideal for strengthening the iliopsoas.
