Final answer:
Manual muscle testing is effective for establishing baseline muscle strength in orthopedic injuries, physical therapy assessments, and geriatric patient evaluations.
Step-by-step explanation:
Manual muscle testing is considered an effective tool for establishing an initial baseline measurement of muscle strength in orthopedic injuries, physical therapy assessments, and geriatric patient evaluations. In orthopedic injuries, manual muscle testing can help determine the extent of muscle damage and guide treatment options. In physical therapy assessments, it is used to evaluate muscle strength and track progress. In geriatric patient evaluations, it can help identify muscle weakness and develop appropriate interventions to improve functional abilities.
