Which basic method is commonly used to evaluate gait abnormalities in PT?

• A. Ultrasound
• B. Observation
• C. Blood tests
• D. MRI

Answer: (B)

Observing gait directly evaluates how a person walks, revealing timing, symmetry, and compensatory patterns that guide treatment decisions. This approach lets a physical therapist see stride length, foot placement, heel strike, push-off, hip and trunk control, and any limp or unusual arcs of movement in real life. It’s quick, noninvasive, and inexpensive, making it the typical starting point for assessing gait abnormalities and planning interventions like gait training, strengthening, or orthotic needs. Imaging tests like ultrasound or MRI show tissue structure, not how someone moves, and blood tests check systemic factors, not gait mechanics. Those tools may be used afterward if a structural or systemic issue is suspected, but for the actual evaluation of how someone walks, observation is the most practical and informative method.
