## What is a hydraulic ankle?

A hydraulic ankle is a specialized prosthetic component that mimics the function of a human ankle joint. It is designed to provide stability, shock absorption, and a range of motion similar to that of a natural ankle. .

### How does a hydraulic ankle work?

The hydraulic ankle uses a system of fluid-filled chambers and valves to control movement and absorb impact. When a person wearing a prosthetic with a hydraulic ankle takes a step, the fluid inside the chambers shifts, allowing the ankle to flex and extend with each stride. This mimics the natural movement of a human ankle, providing a more natural gait for the user. .

### What are the benefits of a hydraulic ankle?

1. **Improved stability:** The hydraulic ankle helps users maintain balance and stability while walking on uneven terrain or changing surfaces.

.

2. **Shock absorption:** The fluid-filled chambers in the hydraulic ankle act as a shock absorber, reducing impact on the rest of the body and decreasing fatigue.

.

3. **Natural gait:** By allowing for a more natural range of motion, the hydraulic ankle can help users walk more comfortably and confidently.

.

4. **Energy efficiency:** The hydraulic ankle can store and release energy with each step, making walking more efficient and reducing strain on the body.

### How is a hydraulic ankle different from a traditional prosthetic ankle?

Traditional prosthetic ankles are typically made of rigid materials and provide limited range of motion and shock absorption. In contrast, a hydraulic ankle uses fluid dynamics to simulate the movement and function of a natural ankle, providing a more dynamic and responsive solution for prosthetic users.

Overall, a hydraulic ankle is a cutting-edge prosthetic component that offers improved stability, shock absorption, and a more natural gait for users. By mimicking the function of a human ankle, it can enhance the mobility and quality of life for individuals with lower limb amputations.
