Final answer:
When using halo traction to immobilize the spinal cord, patients are allowed to move freely within limits set by healthcare providers, although their head and neck movements are restricted to promote healing.
Step-by-step explanation:
When halo traction is being used to immobilize the spinal cord, the client is allowed to move freely within limits. Halo traction is a medical device used to stabilize the cervical spine after injury or surgery, and while it restricts the movement of the head and neck to promote healing, patients are typically encouraged to maintain some level of activity within the prescribed limitations set by their healthcare provider. Activities may include sitting up, standing, or walking if the condition allows, but always under supervision or guidance to ensure the stability of the spine and the safety of the patient.
