What is a remaining power amplifier?

A remaining power amplifier is an assistive device designed to improve the mobility of wheelchair users. It works by amplifying the existing force exerted by the user on the push rims of the wheelchair, thereby reducing the effort required to push the wheelchair. This is particularly useful for people with limited arm or body strength.

The auxiliary drive can be operated either manually, by the user themselves, or electronically, by a built-in motor. This technology enables users to cover longer distances and climb steeper inclines than would be possible with a conventional wheelchair.

How a power amplifier works

A rest amplifier is an effective aid to facilitate locomotion for wheelchair users. The power transmission increases the wheelchair user's propulsion. This is achieved by using motors in the wheelchair wheels. The sensor transmission detects the movement and force that the user exerts on the wheels and forwards this information to the electronic wheelchair drive. This then adjusts the speed and direction of the wheelchair accordingly. The residual force booster therefore enables easier and more efficient movement, especially on uneven surfaces or inclines.

A rechargeable battery provides the energy for operation. Some models also offer additional functions such as a hill climbing program or an automatic braking function.

Advantages of a residual force-boosting auxiliary drive

A power-assisted wheelchair add-on drive offers numerous advantages. It increases the user's mobility and independence by minimizing the physical effort required to move the wheelchair. Longer distances and inclines can be mastered more easily. Another advantage is that the risk of overexertion and associated health problems can be reduced. Users can therefore use their remaining strength more efficiently, which can improve their overall quality of life.

A residual strength booster can also help to improve performance at work and at school by reducing fatigue and increasing productivity. Integration or reintegration into school or work life can be facilitated with a wheelchair drive.

In general, a power-assisted wheel hub drive can help to increase the independence and self-esteem of users by enabling them to explore their surroundings more actively and independently.

Advices for selecting a suitable residual power booster

When selecting a suitable residual power booster, you should consider a number of aspects. Above all, look for user-friendly and easy handling. Also check whether the technical features sufficiently improve your mobility and independence. The battery life is just as important, as it determines the usage time and range.

An innovative bracket can make mounting or dismounting easier (for example for transportation in a car). Models that do not have thru axles and are therefore particularly easy to attach or remove are particularly easy to handle.

You should also pay attention to the quality and durability of the product. A robust and resistant drive ensures long-term use. Before you make a purchase, it is advisable to compare different models. This will give you an overview of the performance and reliability of the drive. Be sure to test the wheelchair drive in your usual environment to ensure that it meets your requirements and needs.

Care and maintenance of a residual power booster

Proper care and maintenance of a residual power booster for wheelchairs is essential to ensure its longevity. It is advisable to read the manufacturer's operating instructions carefully in order to follow all specific manufacturer instructions.

It is important that you charge and check the battery regularly to ensure consistent performance. Ensure that you use the drive unit in accordance with the manufacturer's instructions to avoid overloading. Store the wheelchair add-on drive in a clean and dry environment to prevent corrosion.

By carrying out regular checks, potential problems can be identified and rectified at an early stage. Your medical supply store or the manufacturer of your wheelchair drive will be happy to carry out these checks for you.

Maintenance and care of the wheelchair drive

A power-assisted wheelchair add-on drive requires regular maintenance and care to ensure optimum performance. This includes checking the mechanical parts for wear, checking the electrical connections and cleaning the unit.

It is important that you charge and check the battery regularly to ensure consistent performance. Make sure that you use the drive unit in accordance with the manufacturer's instructions to avoid overloading. Store the add-on wheelchair drive in a clean and dry environment to prevent corrosion.

Where can I buy a residual power booster?

Residual force-boosting add-on drives are often recognized as official aids and can therefore be covered by your health insurance company. Please note, however, that prior approval is required for coverage by statutory health insurance. It is also helpful to have the aid number of the specific device to hand, as this is often required for the application process.

Many manufacturers offer you support when applying for your desired add-on drive and describe the correct procedure step by step.

Frequently asked questions (FAQs) about power-assisted auxiliary drives

Will my health insurance cover the costs of an add-on drive?

In most cases yes, but this depends very much on the individual situation of the applicant and the specific guidelines of the health insurance company.

Is a wheelchair drive classified as a medical device?

Yes, a wheelchair drive is indeed a medical device, as it is used to promote and maintain the health and well-being of individuals.

Is my wheelchair suitable for a power-assisted add-on drive?

Generally speaking, add-on drives can be fitted to most standard manual wheelchair models. Your medical supply retailer will check with the wheelchair manufacturer whether your wheelchair model is compatible.
