Final answer:
It is true that physical therapists assist individuals with musculo-skeletal problems by providing specialized treatments based on their expertise in body mechanics, forces, and torques, as well as tailoring exercises to prevent or rehabilitate muscle atrophy.
Step-by-step explanation:
A physical therapist assists persons with musculo-skeletal problems. This statement is true. Physical therapists (PTs) have advanced degrees and specialize in the mechanics of body movements, often focusing on the treatment of muscle and joint injuries. Their knowledge extends to sports injuries, assessing patient capabilities, strength, balance, endurance, and instructing on equipment use. This necessarily involves knowledge of physics, such as understanding the relationships between forces and torques in the treatment of muscles and joints. PTs are skilled in prescribing exercises that apply forces and torques to revitalize muscles and prevent or treat atrophy, whether it's caused by mechanical injury, disease, or aging.
