Final answer:
While performing the cat-camel exercise, clients should avoid spinal lateral flexion, as this movement is outside the intended range of motion for the exercise and could cause injury.
Step-by-step explanation:
The cat-camel exercise is designed primarily to encourage movement throughout the sagittal plane, involving both spinal flexion and extension. During this exercise, spinal rotation and spinal lateral flexion are not typically advocated since the exercise aims to mobilize the spine in a controlled manner through flexion and extension motions. Spinal rotation and lateral flexion involve movements in different planes, which could potentially cause strain if performed during the cat-camel exercise, especially if the individual is not experienced or warmed up properly. Therefore, the position a client should avoid while performing the cat-camel exercise is:
D) Spinal lateral flexion
This movement is outside the intended motion for this exercise and could lead to injury. The purpose of the cat-camel exercise is to enhance mobility in the spine, strengthen core muscles, and improve postural support, which is primarily achieved through controlled flexion and extension within the sagittal plane.
