Netti Dynamic AdaptPro

We recommend the Netti Dynamic AdaptPro when you are looking for at dynamic chair with the following highlights:

• Reinforced chair

When to choose a complete dynamic wheelchair?

A complete dynamic wheelchair is indicated when the symptoms of the user result in a total extension spasm or in involuntary movements of the hip/back which in most cases also affects the legs.

THE ADVANTAGES OF A DYNAMIC WHEELCHAIRS

• Allowing movement
• Distributing forces
• Increase the total seating time per day
• Increased postural control
• Minimize spasticity
• Increased ADL for the user
• Longer lifetime of the wheelchair

You will find many articles about Dynamic Seating on our Dynamic blog.

Dynamic seat unit

An essential part of the complete Netti Dynamic chairs is the dynamic seat unit. The seat plate will adjust to the user’s extension movements letting the wheelchair work in synergy with the movements.

Our Dynamic chairs are always equipped with a pelvic stabilizer from Body Point to support the function of the dynamic seat plate and to prevent sliding and actively stop a negative seating position.

Freedom of movement will provide the user with a better seating position. With the dynamic seat unit, the user is guided back to the original seating position and in this way we prevent/reduce shear- and pressure forces, which are some of the main factors causing pressure ulcer.

For security reasons the seat plate can be locked during transport or when driving on uneven roads.

Pressure relief

For the Netti Dynamic AdaptPro, we have created a new seatplate with various advantages for long time seating.

A seat plate well ensures pressure relief under the sitting bones and helps decrease long-term skin risk and aids sitting stability. The perforated surface creates ventilation and reduces humidity while being hygienic as it is easy to wipe. A good microclimate is important in the prevention of pressure ulcers, as damp skin sticks more easily to fabric, creating friction and rubbing.

20% lower peak pressure

With the new design of the seat plate we have optained a significantly lower peak pressure on sitting bones compared to a solid seat plate. Our studies have shown that there is more immersion due to the shape of the seatplate. There is also a clear reduction in peak pressure and more importantly, the pressure has moved more forwards - away from the sensitive area around the coccyx and the ischial tuberiosities.

Measurement 1 is from a solid seat plate with Netti Uno seat cushion, at 0-degree tilt, 80 degrees recline and 53 cm seat height from floor to top cushion. Measurement 2 is from a Netti Dynamic AdaptPro seat plate with Netti Uno seat cushion, at 0-degree tilt, 80 degrees recline and 53 cm seat height from floor to top cushion.

The good sitting position is thereby supported and maintained. The result of the measurement shows less pressure on vulnerable areas such as the tailbone and seat bones. Netti Dynamic AdaptPro uses our well-known Netti Seating System with pressure-relieving seat cushions and our back cushions in different designs according to the user's needs.

incredibly stable and safe, even when fully tilted and reclined

The Netti Dynamic AdaptPro has a unique feature with an automatically adjusted foot print. Meaning small foot print for easy maneuvering - but enlarged foot print when the chair is tilted for extra stability and safety for the user.

A compact frame and short wheelbase are often the starting points for achieving the best handling characteristics. Extended wheelbase, on the other hand, is a prerequisite for stability and security in the seat when a large tilt angle is offered. With Netti Dynamic AdaptPro's patented frame construction, we have created the perfect balance between the two extremes.

Patented wheel footprint

Netti Dynamic AdaptPro's unique stability is created by the frame's wheel footprint - the distance between the wheels - as this is automatically extended from 375 mm to a full 465 mm when the chair is tilted 30°. At the same time, the length of the anti tipper is automatically adjusted. Netti Dynamic AdaptPro is offered with a total tilt angle of 30°- a prerequisite for creating variation in the user's sitting position and thus enabling the user to sit longer in the chair.

Ergonomically correct positioned hinge points at the hip and knee joints make it possible for the user to keep the correct seating position over time – also when the seating position is changed, and the back is reclined, or the leg supports are elevated. Situations that otherwise could result in shear and sliding with the risk of discomfort and skin damage.

Correct position of the back hinge

Ergonomic back design with the correct hinge point at the hip ensures that there is no friction of the skin against the back cushion when reclined, which minimizes shear forces and tissue deformation.

Correct position of the knee

Also the user's knee joint and the leg support hinge point are the same - this minimizes the risk of sliding by use of back recline and elevation of the leg supports

We at Netti always seek to improve the user’s overall wellbeing and ability to take part in everyday life activities. The seating advantages of dynamic solutions are among others:

• Being able to sit longer time in the wheelchair
• Skin protection by minimizing sliding and shear
• Optimal posture enabling better eating, drinking and respiration functions
• Less pain

We at Netti are convinced that our Netti Dynamic System can improve quality of life for the wheelchair user as the system will reduce muscle tone, pain and damage to both chair and user.

What happens when an involutary movement occurs in a dynamic wheelchair

When the body part which is set to movement is not fixed (like in the Netti Dynamic System), it can move over a certain distance and loses some of its energy by doing so in an isotonic muscle contraction. This results in a dynamic movement of the part being moved and this movement happens in an open kinetic chain. At the end of the movement the contraction remains often for a longer period, due to the spasm remaining, while the muscle is often in the maximal shortened position and the joints are not able to move any more.

A dynamic system which allows the joints to make a full movement and let the muscle end in the maximal shortened position via an open kinetic chain, will result in the least amount of force in the end position. This means less forced applied to the wheelchair but also less force on the muscle, the joints, and the body.
