What does a muscle score of '5' in Manual Muscle Testing represent?

• A. Full range of motion against gravity, no resistance
• B. Full range of motion against gravity, moderate resistance
• C. Full range of motion against gravity, maximum resistance
• D. Trace muscle contraction

Answer: (C)

A muscle score of '5' in Manual Muscle Testing signifies that the muscle can move through its full range of motion against gravity and can also withstand maximum resistance. This indicates that the muscle demonstrates normal strength and function, which is essential for performing everyday activities and engaging in physical tasks. In a practical setting, this scoring reflects the highest level of muscle performance and is typically what health professionals look for when assessing muscle integrity and function. Therefore, a score of '5' is critical for determining the effectiveness of rehabilitation or interventions aimed at improving muscle strength. The other scores represent different levels of muscle ability, with lower scores indicating reduced strength or capability, making it crucial to distinguish between them for effective assessment and treatment planning.
