Movable Swimming Pool Floor


Movable swimming pool floors, also known as adjustable pool floors, are a testament to patient-centered innovation in aquatic rehabilitation. For many patients, especially those grappling with chronic pain or limited joint mobility, traditional land-based exercises can be daunting or even unattainable. The unique design of the movable swimming pool floor directly addresses these challenges by allowing the water depth to be tailored to each patient’s specific needs. This personalized approach ensures optimal support and resistance, significantly reducing pain and enhancing joint mobility.

The buoyancy of water, a hallmark feature when using movable swimming pool floors, provides a gentle environment that alleviates undue stress on the joints. This is a game-changer for patients, especially those recovering from surgeries like hip or knee replacements, or those enduring conditions such as arthritis or fibromyalgia. The water’s buoyancy not only minimizes pain but also empowers patients to perform exercises that improve their joint flexibility and overall mobility.

Furthermore, the resistance offered by water, when combined with the adjustable pool floor, aids in strengthening muscles around the joints, promoting endurance and further enhancing joint mobility. This is particularly beneficial for patients with conditions like stroke or multiple sclerosis, where improved coordination and balance are paramount.

Safety and accessibility are at the forefront of the design of movable swimming pool floors. They ensure that patients, regardless of their mobility levels, can enter and exit the pool with ease, and even accommodate wheelchair access, ensuring that everyone can benefit from the therapeutic advantages of water.

It’s essential to emphasize that while the adjustable pool floor offers numerous benefits, aquatic therapy should always be conducted under the watchful eye of a trained therapist or physician. Their guidance ensures that patients can maximize their therapeutic gains while ensuring safety and effectiveness.

Endless possibilities

A movable swimming pool floor is a multi functional solution that creates virtually endless possibilities for all types of patients in a hydro-therapeutic pool. It can even be installed in an existing therapy pool. With a movable swimming pool floor, the depth of the pool can be adjusted to exactly meet the needs of the patient. Therefore, the pool can suit all types of patients and facilitate many different training techniques, for example:

  • Water Specific Therapy (WST)
  • Halliwick
  • Bad Ragaz Ring Method (BRRM)
  • Clinical Ai Chi
  • Aquatic motor-cognitive therapy (AMCT)
  • Aquatic Passive Manual Handling (APMH)
  • Aquatic Cardiovascular Training (ACT)

As a result, the pool can be used more efficiently. Our movable swimming pool floor has been designed specifically for use in the rehabilitation and therapeutic sectors.

EWAC Medical not only provides movable swimming pool floors, but also actively contributes to the collection and dissemination of hydrotherapy expertise. This article contains more detailed information about the usage of a movable swimming pool floor in rehabilitation.

Many possible options (See our product configurator)

Underwater treadmill Underwater treadmill can be integrated in a movable swimming pool floor, and be used to perform static walking exercises. The advantage is that the therapist can continuously watch and correct the patient’s movements from one position. This reduces the need for a large swimming pool.
Parallel bars Parallel bars equipped with base plates to place on any position on the movable swimming pool floor. Used for carrying out walking exercises between the two bars.
Underwater bicycle The underwater bicycle is especially designed for exercising circular motion in water. The unique feature of the underwater bicycle is that the resistance increases progressively with the rotation speed of the pedals. Placed on a movable swimming pool floor, the water depth can be adjusted to alter the exercise.
Self adjusting pool stairs Self adjusting stairs. The steps of these self adjusting stairs remain horizontal in each position of the movable swimming pool floor. This ensures optimal accessibility of the pool regardless to the set depth.
Integrated stairs Integrated staircase. This integrated staircase appears as if from nowhere during the downward movement of the movable swimming pool floor. The steps gradually appear one by one. The staircase is equipped with pivoting railing. Video integrated stairs.
Observation window The pool can be equipped with underwater windows. This provides the therapist a complete view of the actions performed by the patient on the movable swimming pool floor.
Counter current or jetstream Counter current unit or jet stream. A jet stream offers exercise resistance to the patient moving against the flow on the movable swimming pool floor. A wall nozzle produces a strong water jet which is aimed at the patient, and depending of the required exercise load, can be softened with air.
Cameras, Lighting Lighting is recommended to improve vision through e.g. underwater windows. The lighting can be monochrome or multi color. In addition, the pool can be equipped with an underwater camera for motion analysis.
Exercise materials Exercise Materials. For use in balancing exercises on the movable swimming pool floor. Can be used in combination with Halliwick or the Bad Ragaz Ring method.

As an alternative to this system, a stair-like transition can be created between two movable swimming pool floors. Contact us for more information.

The importance of the right depth

We believe that it should be possible to change the depth to the needs of the patient and therapist so that the rehabilitation process can proceed optimally. This is why we supply movable swimming pool floors that were especially developed for rehabilitation in the medical sector.

In hydrotherapy, the correct depth for the patient and therapist depends on several variables. The physical length of the patient, the nature of his condition, the selected form of hydrotherapy and the amount of the progress that has already been made. If there is interaction between patient and therapist in the water, the ergonomic position of the therapist will also play a role.

There is no fixed depth that works for each patient and for each therapy. Therefore, a movable floor is the ultimate solution to adjust to the needs of the patient. EWAC Medical movable swimming pool floors are used in the leading rehabilitation centres in the world.

Two types of a movable swimming pool floor

The suspended movable swimming pool floor (up to 45 m2)

With a suspended movable swimming pool floor, the floor is suspended by means of cables that are inserted in the walls of the pool. A water hydraulic cylinder, built into the frame of the floor, can retract the cables which raises the movable swimming pool floor.

The suspended movable swimming pool floor is perfectly compatible with existing pool installations.

The floating movable swimming pool floor (from 45 m2)

The floating type movable swimming pool floor is equipped with floating bodies and can be adjusted using a water hydraulic cable system. Compatible with all pools within the measurement ranges of 40m2 – 140m2.

The floating movable swimming pool floor is perfectly compatible with existing pool situations.

EWAC Medical movable swimming pool floor system meets the most stringent requirements for the hygiene of the water. In fact, our system is the only system available on the market which meets the requirements of EN 15288:2008, Annex A dye test. This means that the hygiene of the water is not affected by the presence of the movable swimming pool floor in the water. Therefore, vulnerable patients run less health risk in a pool with an EWAC Medical movable swimming pool floor.

The movable swimming pool floor has a stainless steel AISI 316 frame, provided with a deck with removable polyester tiles. The movable swimming pool floor can be made in any shape or size. The floor is moved by a water hydraulic system, which ensures that the swimming pool water cannot be contaminated by toxic fluids in the event of leakage.
