What is the grading scale for active movement against gravity?

The grading scale for active movement against gravity is classified as Grade 3. This classification means that the individual can perform the movement through the full range of motion against gravity but does not have the ability to withstand added resistance. In practical terms, a client receiving a Grade 3 rating can move their limb or body part independently without any assistance, which is a fundamental aspect for evaluating muscle strength and functional mobility.

When understanding the grading scale, it's important to recognize that lower grades indicate limited movement, while higher grades denote the ability to perform movements with increasing resistance. For instance, Grade 1 indicates flicker or trace of muscle contraction without moving the joint, while Grade 5 signifies normal strength allowing the individual to lift and hold against maximal resistance. Knowing these distinctions helps in accurately assessing a patient's motor function and determining an appropriate rehabilitation strategy.
