Final answer:
Canes are most frequently used by individuals with weakness on one side of the body, often due to conditions like hemiplegia.
Step-by-step explanation:
Canes are most frequently used for individuals with weakness on one side of the body (C). This weakness can result from conditions such as hemiplegia, which may occur due to a hemisection of the spinal cord or a cerebrovascular incident (stroke). In hemiplegia, one side of the body is paralyzed, greatly reducing mobility and requiring walking aids like canes to provide support and balance.
In contrast, individuals with an amputated lower extremity (A) might use prosthetics and crutches; those with paralysis of the lower extremities (B), such as from spinal cord injuries, might use wheelchairs; and those with poor muscular coordination (D) might use various aids depending on their specific needs.
