Instrumented gait analysis is frequently used today for clinical applications. Its role has expanded beyond the area of gait analysis to aid in clinical decision making for rehabilitation, surgery, adaptive devices, ergonomics, and athletics . Physical therapists are well trained in the area of gait and movement analysis and are, by definition, movement scientists. The evaluation of gait, locomotion, and balance includes a series of tests described in the Guide to Physical Therapy Practice (1). Entry-level didactic requirements include normal gait mechanics and pathological gait for nearly all disabilities. Those in physical therapy training primarily learn observational techniques for clinical gait analysis. In addition, some academic programs provide an introduction to various forms of instrumented gait analysis and their potential to augment the physical therapist's knowledge of gait. Instrumented gait analysis involves information about temporal and linear parameters during gait as well as joint angles, ground reaction forces, and muscle firing patterns.
