Final answer:
Patients should have their elbows at a 15-30 degree angle when using a walker, moving their weaker leg first to the walker, followed by the stronger leg for stability and comfort.
Step-by-step explanation:
When using a walker, the patient's elbows should ideally be at a 15-30 degree angle when they are holding onto the walker. This allows for both comfort and stability. As for which leg moves with the walker, patients are generally taught to move their weaker or affected leg forward to the walker first, followed by the stronger leg. However, the specific instructions can vary depending on the patient's individual needs and physical therapist's recommendations.
