Physical Therapy Assistant Practice Exam 2026 – Complete Prep Guide

The muscle grade 'Fair' indicates that the patient can complete the full range of motion against gravity without any added resistance. This means that the muscle has enough strength to move the limb through the entire range of motion but is not strong enough to resist additional force or resistance. In the context of muscle testing, this grade reflects a functional level where the patient demonstrates the ability to perform movements that may be necessary for daily activities, yet they do not have the strength to enhance or resist those movements.

This grading is critical in evaluating a patient's muscular capabilities and is often part of a broader assessment to identify which interventions may be necessary to improve strength or function. Understanding this enables physical therapy assistants to develop appropriate treatment plans that match the patient's needs and objectives for rehabilitation.
