What is the four-stage gait pattern sequence for using the THKAFO Reciprocating Gait orthosis?

• A. Weight shift right; tuck pelvis by extended upper thoracic; press on crutches; allow left leg to swing through
• B. Stand up; step on crutches
• C. Sit to stand; swing both legs
• D. Pivot on right foot

Answer: (A)

In THKAFO Reciprocating Gait training, moving forward is taught as a four-part sequence that coordinates weight, trunk position, crutch support, and the swing leg. First, you shift your weight onto the stance side (the right) so the other leg can move without bearing load. Next, you tuck the pelvis by extending the upper spine, which positions the pelvis correctly and enables the opposite hip to flex so the swing leg can come through smoothly. Then you press on the crutches to provide stability and forward propulsion. Finally, the opposite leg swings through under the control of the reciprocating mechanism. This order matches how the orthosis forces the legs to move together: weight shift sets up the swing, the trunk/pelvis position aligns the hips for flexion, crutch support aids stability and momentum, and the swing leg completes the step. Other options describe more general or unrelated movements, or omit the specific four-part coordination required for THKAFO gait.
