Final answer:
After a posterior approach total hip replacement, leg raises should be avoided during Pilates to prevent hip dislocation. Squats, arm circles, and deep breathing exercises are safer options with proper guidance.
Step-by-step explanation:
For a client who has undergone a posterior approach total hip replacement surgery, certain movements should be avoided during the initial phases of recovery to prevent dislocation of the new hip joint. In the context of a Pilates fitness program, the movement to avoid is b) Leg raises. These involve bending or lifting the leg away from the midline of the body, which can put strain on the hip joint and potentially lead to dislocation, especially if the movement includes hip extension or external rotation. The other options: a) Squats, c) Arm circles, and d) Deep breathing exercises, are generally considered safe, provided they are performed correctly and with the guidance of a qualified instructor who is aware of the client's medical history.
