Physical Therapy Assistant Practice Exam

In a manual muscle test, what does the grade 'Good' indicate about the patient's strength against gravity?

1. Complete range of motion without resistance

2. Unable to complete the full range against gravity

3. Range of motion completed against gravity with minimal-moderate resistance

4. Range of motion completed against gravity without strength assistance

The correct answer is: Complete range of motion without resistance

The grade 'Good' in a manual muscle test indicates that the patient can complete the full range of motion against gravity and is able to maintain that position against some level of resistance. This means that while they can perform all movements required, they might not be able to withstand a substantial amount of resistance but still demonstrate adequate strength. Option A suggests that the patient can complete the range of motion without resistance, which in this context would imply a level of strength that may not fully align with the definition of 'Good.' Instead, the grade signifies that the patient has sufficient strength to maintain movement against gravity but may be challenged to do so under significant resistance. Option B describes an inability to perform the full range against gravity, which falls into a lower strength category, typically classified as 'Fair' or 'Poor.' Option C inaccurately describes the patient's capabilities. It suggests that a minimal to moderate resistance is required, which may suggest a higher strength level, typically classified as 'Fair+' or 'Good+'. Option D does not accurately reflect the definition of the 'Good' grade, as 'Good' does not necessarily imply that the patient has full strength but rather an ability to work against gravity effectively. Therefore, the correct understanding of the grade 'Good
