Final answer:
Amputations and cerebral palsy both fall under the category of Musculoskeletal disabilities, as they impact mobility and physical functioning.
Step-by-step explanation:
The disability grouping that includes amputations and cerebral palsy is Musculoskeletal disabilities. Cerebral palsy is a condition caused by injury to the developing brain, usually affecting the parts of the brain that control body movements. Amputations result in the loss of a limb or limbs, which falls under musculoskeletal issues as well. These conditions primarily affect a person's muscles, bones, ligaments, or tendons, thereby challenging their musculoskeletal system and impacting mobility and physical functioning.Amputations involve the loss of a limb, while cerebral palsy is a condition that affects movement and muscle coordination.
