  • Traditional power wheelchairs (PWC) use an armrest mounted joystick controller. Such devices force a change in body posture and weight distribution with deleterious effects over time. When operating a PWC with an armrest mounted drive control, the user must lean on the armrest where the joystick is mounted in order to improve drive control. However, driving from midline can facilitate improved PWC control and body posture allowing seating products to do what they are intended to do.

    The Active Controls Center Drive System was developed to allow midline mounting for power chair joysticks and alternative drive controls. There are several benefits to the operation of a PWC at midline, including better postural alignment and weight distribution. Both benefits are vital in the

    preservation of skin health and pressure distribution, allowing seating products to maximize their function.

    Using a center position control, the operator is in a more intuitive and functional position that aligns the visual field with the center of the chair’s travel path. Operating a power chair with its controls at midline will often increase the efficacy of the user.

    Countless number of joystick hand controls are damaged due to miscalculations of the location of obstructions and hallway walls caused by its side mounted position. The midline position prevents damage from occurring to what in many PWCs is the most expensive and fragile component.

    In this study we compare the 3D kinematics and Dynamic EMG of the same subject using a traditional armrest controller and a center mounted one. Body posture, arm biomechanics and muscle activation patterns were recorded under both conditions and demonstrate better biomechanics for the central mounted controller compared with the side mounted one.

    Subjects sit more erect and use less force to drive central mounted controls. They report more comfort while driving them and an improved sense of control over the wheelchair.

  • The Center Drive System (CDS) Saves Wheelchair Clinics and Providers Time and Money

    “I am a huge proponent of the Active Controls Center Drive System for use in wheelchair clinics. It is SUCH a time saver. In clinics, the time to conduct a wheelchair assessment is becoming more and more of an issue because it is usually limited to 60-90 minutes by third party payers.

    “Follow up visits to clinic are especially hard to justify. Because the modular Active Controls System eliminates the time between assessments of different controls by 20-30 minutes, it dramatically limits the number of follow up visits needed.

    “With the cost of clinic time of $400-$500 per hour, the return on investment of a sample evaluation kit is a capital expenditure that pays dividends in the first year while benefiting the patient and clinician.”

    - Erin Michael, PT, DPT, ATP/SMS, Seating and Mobility Specialist International Center for Spinal Cord Injury, Kennedy Krieger Institute

    Active Controls Rehab Solutions are a Breakthrough for Wheelchair Clinics

    A sample evaluation kit consists of 4-5 complete modular drive controls mounted on 4-5 different platforms, and a socket installation kit. The universal drive control modular socket kit installs in minutes to any make or model power wheelchair.

    The multiple benefits of a sample evaluation kit are:

    • Modular connection of pre-assembled joysticks and alternate drive controls increases the efficiency and effectiveness of wheelchair assessments.

    • For the first time, clinics/providers now have the tools to trial any existing alternate drive control and instantly position it at midline for use by the hand(s), chin, lip, tongue or head.

    • Clinicians and their patients are relieved of the energy-sapping efforts required to perform multiple wheelchair transfers to assess different types of drive controls.

    • Side-by-side comparisons between two similarly successful trials can be conducted to instantly gauge the patient’s opinion of which control works best and is most comfortable.

    • In a clinical setting, the CDS mounted alternate drive controls do not require a technician to install and the need for reprogramming the chair is limited to changing from a proportional control to a switched control such as a head array.

    • By investing in a set of 4-5 different controls pre-assembled to various Active Controls midline platforms, it establishes the clinic and providers who are its’ early adopters with a progressive reputation in the community it serves.

    • The supervisors, clinicians and technical staff are energized by the quality time it frees up in clinic to work with their patients and document the medical justifications for the control selection and location.


  • Front Socket A modular socket mounted at the front of the seat allows quick disconnection from the midline drive position for safe, easy transfers in and out of the chair. The front socket can also be mounted with an optional flip-down or removable bracket, depending on the needs of the client and their method of transfer.

    Rear Socket A modular socket mounted behind the seat allows the carer/ spouse to seamlessly transfer the drive control from the primary drive position to an attendant position. A head array or swing-away chin control can also be mounted in the rear position.

    Side Socket A side-mounted socket can be either powered or non-powered. This socket offers a safe, stable “holstering” position of the drive control during transfers. When powered, it enables the client to move close to tables/ desks to perform activities.



    The Active Controls products featured in this Reference Guide can be easily installed on any power wheelchair using the patented mast and socket system. The electrical connection for the drive control is made through military grade gold-plated spring pins in the mast, and target contacts in the socket.

    Improved patient outcomes and a ground-breaking clinical research study confirm numerous advantages of the Active Controls modular system. Wheelchair clinics and wheelchair dealers worldwide have increased the efficiency and effectiveness of wheelchair assessments.
