First, choose a crutch with an appropriate height. When standing, the top of the crutch should be flush with the bottom of the palm, and the elbow should be slightly bent, but it should not be excessively straight or bent.

Hold the crutch, hold the top of the crutch with one hand and the side near the bottom with the other hand.

When walking, put the crutch opposite to the injured or weak side. For example, if you hurt your right leg, put the crutch on your left.

Put the crutch in front of your body first, and then move the injured or weak leg to the front of the crutch.

After stabilizing your body, transfer your weight to the crutch and move your healthy legs to the front of the crutch.

Next, stabilize the crutches on the ground and transfer the weight to the crutches and healthy legs.

When moving crutches and healthy legs, keep a steady rhythm and ensure that the position of crutches remains stable.

When you take a step, first move the crutches and healthy legs, and then move the injured or weak legs to the front of the crutches.

Repeat the above steps to continue walking.

The above are some basic steps, but the correct posture and skills of walking on crutches may vary according to individual circumstances. If you need more detailed guidance, it is recommended to consult a doctor, physiotherapist or rehabilitation expert, who can provide professional advice and guidance according to your specific situation.
