What does a score of 2 on the Manual Muscle Test (MMT) indicate?

A score of 2 on the Manual Muscle Test (MMT) indicates the ability to move through a partial range of motion with gravity eliminated. This scoring system is used to evaluate muscle strength and function by assessing how well a muscle can contract and produce movement.

In the context of MMT, a score of 2 means that the individual can perform some degree of movement, but it is not sufficient to overcome the force of gravity. This typically occurs in a position where gravity is minimized, such as lying down. This information is vital for rehabilitation professionals to design appropriate interventions and track progress in strength and functional abilities.

The other score options reflect different levels of muscle function: the ability to perform full range of motion against gravity, which corresponds to a higher score, indicates stronger muscle capabilities; the inability to imitate movement with a noticeable muscle contraction signifies a lower score where minimal strength is present; and the inability to detect muscle contraction visually suggests that there is no observable muscle activity at all, which would correspond to a score even lower than 2. Understanding these differences is crucial for accurately assessing muscle strength and guiding treatment strategies.
