Answer 1

ANSWER:

Kinematic analysis evaluates movement patterns, including the movement of the body, and specific angles between body segments (joint angles) as the body moves through the gait cycle. Observational gait analysis is a qualitative method of kinematic analysis. When kinematics is measured by instrumented analysis, it is considered a quantitative gait analysis. Observational gait analysis is the visual inspection of walking. Although not as reliable as quantitative gait analysis, observational gait analysis is the method most often used by practitioners.
