Final answer:
Forearm crutches are commonly used by patients with Cerebral palsy, a condition affecting the brain's control of body movements, resulting in a range of motor function impairments. The crutches assist by providing balance and support for mobilization.
Step-by-step explanation:
Forearm crutches are often used by patients who experience difficulty in walking due to various conditions. Among the listed options, C. Cerebral palsy is a condition that may require the use of forearm crutches. Cerebral palsy is caused by injury to the developing brain, which usually affects the parts of the brain that control body movements, and can range from mild muscle weakness to severer difficulties in walking and talking. While forearm crutches can also support individuals with other conditions like a fracture of a lower extremity or an amputated leg, cerebral palsy is a chronic condition that often necessitates long-term mobility assistance.
Potential reasons to use forearm crutches might involve the need for improved balance, weight distribution, or assistance during long-term rehabilitation. It is worth noting that paralysis on one side of the body, such as that resulting from spinal cord injuries, may require different types of support depending on the severity and nature of the paralysis.
