Waterproof Prostheses: What are they and do you need one?
In the world of prosthetics, the demand for waterproof solutions is increasing, as more users look for the freedom to use them in water-based activities like showering, swimming, outdoor adventures or just walking outside in unpredictable weather. Waterproof prostheses open new doors for enhanced mobility and independence, offering versatility and peace of mind. In this comprehensive guide, we'll explore the various features, materials, and maintenance tips for waterproof prostheses, the limitations users may face, and examples of leading products from Ossur, Ottobock, and Taska. We'll also discuss waterproof covers that can temporarily convert standard prostheses into waterproof ones.
Why Waterproof Prostheses Matter
Waterproof prostheses are essential for individuals who lead active lifestyles or simply want the convenience of not having to remove their prosthesis in everyday water-based situations. Whether it's taking a shower, swimming in a pool, or going to the beach, these prostheses allow users to stay engaged in their activities without worrying about potential damage to their device.
For many lower limb prosthetic users, the ability to take a shower, whilst standing with their prosthesis, especially when there are no shower seats available is much safer. Meanwhile, athletes or water enthusiasts may want to swim, participate in water sports, or enjoy beach vacations without needing to switch between prostheses. Waterproof prostheses provide the flexibility to live life without interruption, while also enhancing the wearer’s confidence and independence.
Features of Waterproof Prostheses
Waterproof prostheses are designed with specific features that make them suitable for wet environments, offering a balance between functionality, durability, and comfort. Here are some of the key features to look out for:
a) Water-Resistant Materials
Waterproof prostheses are built using materials that can withstand exposure to water without corroding, rusting, or losing functionality. These materials often include:
Silicone / Polyurethane: A non-porous and durable material, silicone and PU are commonly used for prosthetic liners and covers. They are water-resistant and easy to clean.
Titanium: Lightweight and corrosion-resistant, titanium is used in many high-end prosthetic components like knee joints, connectors, and adapters.
Carbon Fiber: Known for its strength and lightweight properties, carbon fiber is often used in prosthetic foot components and frames. It is resistant to water, but regular maintenance is still important.
b) Sealed Electronics
For prosthetic devices that include electronic components, such as microprocessor knees and myoelectric hands, the electronics must be sealed from water exposure. These devices are equipped with waterproof casings or housings that protect the internal mechanisms from water damage.
c) Grippy Surfaces
Waterproof prostheses often feature textured surfaces that provide enhanced grip in wet conditions. This is especially important for users who participate in water sports or need secure footing in showers and on slippery surfaces.
d) Suspension Systems
Waterproof suspension systems are not only made of waterproof materials but also need to securely attach the prosthesis to the user when in water.
Examples of Waterproof Components from Leading Manufacturers
There are several leading manufacturers of prosthetic components that offer waterproof or water-resistant options. Let's take a closer look at some products from Ossur, Ottobock, and Taska.
Ossur Pro-Flex Terra
a) Ossur
Ossur, a prominent name in the prosthetics industry, offers high-quality waterproof prosthetic options. One notable product is the Pro-Flex Terra Foot, designed for active individuals who need a prosthetic foot capable of withstanding water exposure. This foot is highly durable, lightweight, and offers exceptional energy return. It's ideal for water-based activities like walking on the beach, swimming, or even hiking in wet environments. The foot is designed with non-corrosive materials and sealed components to prevent water infiltration.
Ottobock Genium X4
b) Ottobock
Ottobock is a global leader in prosthetics, known for producing reliable and advanced devices. One of their standout waterproof product is the Genium X4 Microprocessor Knee. It is waterproof (IP68), dustproof, and corrosion-resistant to salt and chlorinated water. It's designed for moderate to highly active users who engage in swimming, running, or other intense physical activities. This prosthetic knee allows the user to walk with a natural gait and transition smoothly between wet and dry environments.
c) Taska
Taska is renowned for developing prosthetic hands with cutting-edge functionality. The Taska Hand CX and Gen2 are waterproof (IP67) myoelectric hands that stands out for its unique ability to function extremely well in water. These hands are one of the most advanced myoelectric hands available on the market. Not only does it offer excellent dexterity and grip strength, but it's also fully waterproof. Users can wash dishes, shower, or even swim without worrying about damaging the electronics inside the hand. The hand is made from durable, water-resistant materials, and its waterproofing ensures that the motorized components and electronics remain safe from water exposure.
Maintenance Tips for Waterproof Prostheses
While waterproof prostheses are designed to withstand wet environments, proper care and maintenance are essential to ensure their longevity and optimal performance. Here are some tips to keep your prosthesis in good shape:
a) Rinse After Use
After exposure to salt or chlorinated water, rinse your prosthesis thoroughly with clean water to remove any residue. Salt and chlorine can corrode materials over time if not properly rinsed. While your knee or hand may be waterproof not every component in your prosthesis may withstand salt or chlorinated water.
b) Dry Thoroughly
Allow your prosthesis to dry completely after being submerged or exposed to water. This is especially important for liners, straps, and covers. Use a soft towel to wipe it down, and leave it in a well-ventilated area to air-dry. Moisture between the liner and your skin increases chaffing which can lead to skin injury.
c) Regular Inspections
Check your prosthesis regularly for signs of wear and tear, especially in areas that come into contact with water frequently. Look for cracks in the waterproof seals, damage to liners, or corrosion on metal components.
d) Follow Manufacturer Guidelines
Always adhere to the maintenance recommendations provided by your prosthetist and the manufacturer. Specific cleaning solutions and methods may be necessary to ensure the water-resistance of your device remains intact.
Limitations of Waterproof Prostheses
Despite their impressive capabilities, waterproof prostheses do have some limitations that users should be aware of:
a) Not All Products are Completely Submersible
While many prosthetic devices are water-resistant, not all are designed for full submersion. Certain components, such as electronics, may still be vulnerable to water damage if submerged for prolonged periods in deep water. Check with your prosthetist some devices are just splash resistant.
b) Limited Range of Motion
Waterproof prostheses may have more limited flexibility compared to standard prostheses, especially when designed for low-impact activities like swimming and showering. However, these types of prostheses are less common now as new high functioning prosthetic components are now developed with waterproof features.
c) Weight
Some waterproof prostheses may be slightly heavier due to the materials and additional waterproofing features. This can affect balance and comfort, especially during long periods of use.
Waterproof Covers: A Simple Solution for Regular Prostheses
If your existing prosthesis is not waterproof, there are waterproof covers available that can make it suitable for use in wet conditions. These covers are designed to protect your prosthesis from water, offering a temporary waterproofing solution. DryPro Waterproof Prosthetic Leg Cover is a vacuum-sealed solution that keeps your prosthesis completely dry. It's particularly useful for showering and swimming.
Usage Tips for Waterproof Prostheses
Maximizing the benefits of your waterproof prosthesis comes down to understanding how to use it effectively. Here are a few practical tips:
Test it Before Water Use: Before jumping into the pool or ocean, test your prosthesis in a controlled environment like a bathtub to ensure it's fully functional in water. Some waterproof prosthesis float in water making swimming challenging for some.
Practice Walking on Wet Surfaces: Wet environments can be slippery, so practice walking in wet conditions to ensure you're comfortable and confident with your footing. Soaps and hair conditioners in bathrooms or algae on rocks can make very slippery surfaces so always be careful.
Use Non-Slip Footwear: Consider wearing non-slip water shoes or sandals for extra traction in wet environments.
Conclusion
Waterproof prostheses are a remarkable advancement in the field of prosthetics, offering individuals the freedom to engage in water-based activities without compromising the function or durability of their device. Whether you're swimming in the ocean, hiking in the rain, or simply taking a shower, these prostheses enhance your mobility and quality of life. By choosing the right waterproof prosthesis and following proper maintenance routines, you can enjoy a more active and worry-free lifestyle.
