What does MMT grade 4 represent?

MMT grade 4 represents the ability to hold a test position against strong pressure, indicating that the individual has good strength but may not be able to withstand maximum resistance. In the context of manual muscle testing (MMT), this grade indicates that the muscle can function effectively in daily activities but may show some fatigue or weakness under high demands.

The implications of grade 4 suggest that while there is significant strength, the individual may not be at peak performance levels, which is crucial for rehabilitation and fitness assessments. When assessing muscle strength, a grade of 4 can indicate that the muscle is functioning adequately for most activities but may still require further training or improvement to reach full strength (grade 5) where there is complete resistance against maximal pressure.

Understanding the distinctions between the various grades of muscle strength is important for developing effective rehabilitation programs and for setting appropriate goals in fitness training.
