What is indicated by a score of 3/5 in manual muscle testing?

A score of 3/5 in manual muscle testing indicates that a patient has the ability to move through the complete range of motion against gravity, but without any additional resistance. This means the muscle can perform the intended movement successfully, but cannot sustain any load that would require additional strength.

In the context of manual muscle testing, a score of 3 indicates an average level of muscle strength where the patient is able to perform the movement independently but is not strong enough to overcome external resistance. A score above this threshold would suggest the ability to handle resistance, while a score below would mean limited movement capabilities either through partial range or against the influence of gravity.

Understanding this scale is crucial for physical therapists as it helps determine the appropriate level of intervention and rehabilitation strategies for patients based on their muscle strength.
