What does a documentation of grade 4 muscle strength indicate?

A documentation of grade 4 muscle strength indicates that the tested muscle can achieve a full range of motion against gravity while being able to tolerate some resistance. This grading is part of a common muscle strength assessment scale (typically ranging from 0 to 5) used in clinical settings to evaluate muscle function.

In this grading system, grade 5 represents normal strength, meaning the muscle can move through a full range of motion against gravity with full resistance. Grade 4 signifies that while strength is slightly diminished and the muscle can still perform the movement well, it requires some assistance to overcome resistance effectively.

Monitoring muscle strength is essential in various healthcare and rehabilitation contexts, as it helps assess recovery, functional capability, and the need for interventions. Understanding the nuances of these grades helps clinicians tailor treatment plans based on the patient's capabilities and rehabilitation goals.
