Which leg should move first when walking up stairs using crutches?

When walking up stairs using crutches, the unaffected or good leg should move first. The reason for this is to provide stability and support as the individual ascends the stairs. By leading with the unaffected leg, the person can place weight on the healthier leg, which typically can bear more weight and provides a stronger base of support.

After the unaffected leg has moved up to the next step, the crutches can then be raised and positioned on the same step, followed by bringing the affected leg up. This method helps ensure that the individual maintains balance and reduces the risk of falling. The focus on the good leg first is crucial as it allows the person to effectively use their strength to propel themselves upwards in a safe manner.
