Final answer:
A hemi-walker can be used in different walking patterns depending on the movement of both legs and weight-bearing. It can involve reciprocal movement, simultaneous movement, or modified gait patterns.
Step-by-step explanation:
A) A walking pattern involving reciprocal movement of both legs and the hemi-walker, with weight-bearing on the unaffected side.
B) A gait pattern where both legs move simultaneously, and the hemi-walker is advanced along with the affected leg, allowing for full weight-bearing
C) A walking technique with reciprocal movement of the hemi-walker and both legs, with no weight bearing on the unaffected side.
D) A modified gait pattern where the hemi-walker is stationary, and the unaffected side moves forward with weight-bearing.
