Physical Therapy Assistant Practice Exam

What does the muscle grade 'Fair' indicate in terms of a patient's strength during testing?

1. Cannot complete more than half the range of motion against gravity

2. Has sufficient strength to overcome moderate resistance

3. Completes range of motion without any resistance

4. Can complete the full range of motion against gravity

The correct answer is: Cannot complete more than half the range of motion against gravity

A muscle grade of 'Fair' indicates that the patient can complete the full range of motion against gravity but does not have the strength to overcome any additional resistance. This grade is significant in assessing a patient's strength, as it demonstrates that the individual has some functional ability despite limitations in strength when faced with resistance. The 'Fair' grade is typically represented as a 3 out of 5 in muscle testing. It reflects a critical point in the assessment continuum where patients may still function in daily activities but may struggle with tasks that require more strength. Understanding this can help guide treatment and rehabilitation plans focused on strength improvement and functional recovery. In contrast, the other options represent different strength levels: the inability to complete more than half the range of motion against gravity signifies a lower grade, while having enough strength to overcome moderate resistance suggests a higher functional capacity than 'Fair.' Completing the range of motion without resistance indicates a lack of gravity challenge, again denoting a different strength assessment. Each grade serves to clarify the patient's capabilities in relation to therapeutic goals.
