Contractures

Explanation:

Contractures: The term is defined as the deformity and shortening of muscles due to lack of proper use. A person who develops contracture lacks thick collagen fibers. It can be reversed if the detection of the joint occurs before the complete immobilization.

Contractures hinder the joints to move freely, that is if a person is having a knee contracture, for example, it can cause pain and difficulty while walking or straightening of the leg and with the passage it can even restrict walking.

It can occur in various parts of the body, including muscles, joints, and skin.

Treatment:

1. Physiotherapy.

2. Heat therapy.

3. Medicines.

Example: Cerebral palsy, and Hip dislocation.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
