A Manual Muscle Testing score of '3' reflects which level of strength?

A Manual Muscle Testing (MMT) score of '3' indicates a level of strength categorized as 'Fair.' This classification signifies that the muscle can maintain a contraction against gravity but cannot hold against any additional resistance.

In practical terms, when a muscle is rated as Fair, it demonstrates the ability to perform a movement through the full range of motion without assistance or added resistance, which is an essential factor in evaluating a patient's functional capabilities. This level of strength is crucial for individuals who may be in rehabilitation or recovery, as it suggests that the muscle is functional enough to perform daily tasks that do not require additional force.

Understanding this scoring system is important for clinicians, as it allows them to document and communicate a patient's progress accurately. It also helps guide treatment plans based on the patient's current capabilities and future rehabilitation goals.
