Final answer:
The Manual Muscle Testing (MMT) scale should be used to test the muscles of the cervical spine, small digits, or scapula and to perform a quick screen for strength.
Step-by-step explanation:
If you want to test the muscles of the cervical spine, small digits, or scapula, or if you want to do a quick screen for strength, you should use the Manual Muscle Testing (MMT) scale.
MMT is a method used by healthcare professionals to measure the strength of specific muscle groups. It involves applying resistance against the muscle's movement and grading the strength on a scale of 0 to 5, with 0 indicating no movement and 5 indicating normal strength.
Using the MMT scale allows you to assess the strength of targeted muscles accurately and objectively.
