What are a few advantages the HydroWorx 300 technology provides?

Compared to land-based unweighting treadmills, the 300 offers the same functionality but with the additional benefits of warm water therapy such as buoyancy, the relaxing effect of warm water on muscles and joints, the strengthening benefits of additional resistance and hydrostatic pressure to reduce swelling and promote healing. In addition, the 300 allows you to move and rotate freely with plenty of space to execute multi-planar activities such as forward and backwards walking or running, side shuffle and karaoke.

The completely integrated underwater treadmill (speeds from 0 to 10 mph) allows for correct simulation of land-based biomechanics. Sports specific exercises such as sprinting, marching, back-pedaling, shuffling, lateral braiding steps and plyometric activities are especially effective when performed on an underwater treadmill.

The video system allows the athletic trainer or physical therapist to diagnose gait patterns for immediate corrections. The athlete or patient benefits from being able to see himself or herself on the flat screen monitor and execute the desired protocol faster, thus speeding up the healing process.

The adjustable 10” touch screen panel controls all functions of the 300 Series. This gives the athletic trainer, physical therapist, athlete or patient complete control from inside or outside the tank during treatment or conditioning sessions.

What are dimensions of the treadmill?

The standard unit walking belt is 19” x 45” // 483mm x 1,143mm

How long does it take to fill and empty the trainer tank?

Three minutes or less, depending on the length of plumbing runs between the equipment.

Not only is this pool an impressive visual in our clinic, it allows us to reach all of our patients more effectively — from athletes to geriatrics and pediatrics. I became a therapist to help people move. And there is no better way to do this than in a HydroWorx pool.

The Orthopedic and Sports Medicine Institute Weldon Russo, Director

We’ve had remarkable success stories from various individuals including Major League Soccer players returning to play months earlier than expected and crediting that in large part to their use of the HydroWorx 2000 underwater treadmill.

Fortius Sport & Health Caleb Cousens, Online Marketing Coordinator

Investing in high-quality equipment and the associated implementation costs may seem daunting, but when these state-of-the-art tools help build our business, brand us as the facility of choice in our communities and increase the scope of our operations, they are investments worthy of a deep dive.

Clear Choice Health Care Geoff Fraser, Senior Vice President of Operations

"HydroWorx allows us to return players to training in a much better physical condition than if we did not have it. For example, the integrated underwater treadmill and resistance jets allows us to work specific running drills performed on the field much earlier for our typical injuries such as ankle ligament sprains, knee ligament sprains and fractures.”

Manchester United FC Neil Hough, Head Physiotherapist

Our statistics thus far show 28% increase in center of gravity, 37% in lower body strength, and 19% of clients moved out of fall risk category. We will continue to use FallProof H2O and the HydroWorx 1200 Series, as we are getting great results and the best part of all, our participants love it too!

Lakeview Village Jackie Halbin, Living Well Manager

When considering return to sport, the difference between a normal swimming pool and a HydroWorx is half [when compared to land rehabilitation]. It is a 20 – 25% improvement from getting a player back from a typical ankle, knee or muscle injury.

West Bromwich Albion FC Dr. Mark Gillett, Head of Performance

Our HydroWorx pool gives our patients a great way to exercise without pain. By using aquatic therapy with an underwater treadmill, they can oftentimes return faster to the sports and activities they love doing earlier than they would be able to with land-based therapy alone.

OrthoCarolina Cheryl Bennett, Aquatic Therapist

"The HydroWorx pools are the highlight of our new Sports Medicine Center! We are now able to get people healthier and back to play quicker and stronger than ever before!"

Butler University Ryan Galloy, Director of Sports Medicine

The HydroWorx pools allows us to provide the best care possible for our athletes by giving us a tool to unload body weight while still allowing them to get work done whether it be a cardio or a rehab session. The pools play a big role in their recovery from sore muscles to major surgeries.

University of Utah Katherine Lorens, Assistant Athletic Trainer

Overall, we have far exceeded our volume and revenue projections. Many local physicians want aquatic therapy as part of the treatment plan for their patients. The physicians have a lot of trust in us. Every single day we have patients in the pool — sometimes it’s been booked to capacity. We do more volume than any other therapy provider in a two-county region.

Cox Monett Clinic Kevin Norris Rehab Manager

Besides a clinician’s manual skills a HydroWorx pool is the best tool you can have in your facility, period!! Its versatility is unmatched with the ability to effectively and efficiently treat any type of orthopedic condition.

With this level of support, you can rest easy knowing your rehabilitation and exercise program is a safe way to avoid the risk of additional injury.

Additional Features and Benefits of Our Unweighting Treadmills

This intuitive and portable underwater, anti-gravity treadmill system allows for easily controlled aquatic therapy sessions. The touch screen interface easily adjusts water depth and underwater treadmill speed and can be positioned conveniently for user or physical therapist. When using the treadmill, users can accelerate up to 10 miles per hour.

With optional extras, such as an underwater camera and pediatric handrails, patients of all ages and ability can benefit from this easy-to-operate benchmark product.

The outward opening door allows patients or athletes easy access to the treadmill, unlike having to climb or be lowered into a swimming pool.

Controlling the water temperature to suit individual needs allows for functional rehabilitation. Warm water can assist circulation, pain management and relaxation, boosting patients’ confidence and mobility.

“The HydroWorx 300 is an important part in nearly every stage of our rehabilitation process beginning with the activation of the metabolism and promotion/improvement of the healing process, the re-establishment of gait and movement patterns, over conditioning of the cardiac system, right up to physical therapy and massage.”

– Carsten Redemacher, Bayer 04 Leverkusen Sports Scientist and Head of Rehabilitation

3 Locations For The HydroWorx 300

The Underutilized Floor Space or Room in Your Private Practice Physical Therapy Clinic

Often physical therapists are restricted in what they can include in their clinics due to their limited amount of space, or are unable to perform construction in a leased space. Fortunately, the 300 Series requires a small footprint which means it can be placed right on your treatment floor or in an adjacent room. With the 300 close by or in line of site, a PT or PTA can treat multiple patients at a time.  Clinic owners can now offer their patients an advanced rehabilitation tool to decrease rehab time frames, increase muscle strength and improve functional outcomes without adding staff at convenient financing rates.  Email us to learn how you can take advantage of this year’s Capital Equipment Tax Incentive with the HydroWorx 300.

On the Deck of the Static Pool in Your Senior Living Wellness Center

Requiring a small footprint, senior living wellness and recreation facilities can easily include warm water underwater and resistance jet technology next to their larger static pool or in the wellness center where residents gather for exercise. Ease chronic pain, arthritis or achy joints with warm water therapy and multi-planar movements of the 300 underwater treadmill.

The Corner of Your Athletic Training Room

Athletes can reap all of the same rehab and training benefits with the 300 Series as they would with a HydroWorx pool. If you’ve deemed hydrotherapy not possible due to limited space, the small footprint of the 300 gives clinicians the ability to offer an unweighting treadmill device with the benefits of warm water therapy almost anywhere in your training room.  This system offers athletic trainers and strength & conditioning coaches a way to accurately simulate land-based activities in all directions such as walking, retro-walking, jogging and sprinting with underwater treadmill speeds ranging from 0.1 to 10 mph despite space and construction budget limitations.
