Amyotrophic Lateral Sclerosis (ALS) is a specific disease that causes the death of neurons in the brains and spinal cord which control voluntary muscles.
ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. This results in loss of motor function and muscle weakness, in difficulty in speaking, swallowing, and eventually breathing.
The disease is progressive, meaning the symptoms get worse over time. Currently, there is no cure for ALS and no effective treatment to halt, or reverse, the progression of the disease.
Patients in the later stage of the disease may become totally paralyzed. At that moment, the combination of some mo-Vis devices can offer most ALS patients a complete functional solution and opens new perspectives for a better quality of life.
The Multi Swing is a versatile, motorized mounting arm to be mount on a power wheelchair and designed to be
used among others as a chin control. The Multi Swing movement (swing away horizontally or vertically),
speed (start speed, acceleration sector, nominal speed), angle (arm movement programmable from 1°
up to maximum opening angle of 274°) and connection (multiple input buttons possible, activation
methods and output actions can be altered) are fully adjustable to the users preferences and needs with the
mo-Vis Configurator software. The arm can be positioned to drive and can be moved upwards or sideways by
pressing a button whenever needed.

The Multi Joystick is designed to be used as chin joystick and is a full proportional joystick with a reduced
amplitude (travel from center is 8mm ) and minimal force requirement (only 50 gr). The Multi Joystick is a small,
proportional joystick which requires significant less power and movement compared to a normal joystick and
meets perfectly the functional needs of the ALS patient.

The Multi Swing in combination with the Multi Joystick offers effective and comfortable solutions for the customer,
as well as an aesthetically pleasing look. One or two Twister switches on bended tube can be mount besides the
joystick and immediately plugged into the housing as on/off and mode switch. The elegant and light sensitive
Twister switches are three dimensional adjustable and react at the lightest touch, even on the side of the switch.
The joystick cable enters inside the tube of the swing away arm and leaves the pipe at the backside
of the power wheelchair. The huge advantage is not only a better protection of the joystick cable against damage
but also a discreet and lovely look.

Most customers who are already familiar with the use of a chin control usually opt for the combination
of the multi joystick with two switches, one for on/off and one for mode. But with the Configurator software you
can program the operation of the connected switch to the Multi Swing and multiple functions can be assigned
to one switch.
So, you do not need 3 different switches to activate the arm, the power on/off and the mode of the power chair.
You can assign the three functions to one switch.
It can be hard to maintain control of the wheelchair outdoors on an uneven, bumpy road or on cobbles.
Certainly for those who use a chin control, combined with a sensitive joystick such as the Multi Joystick.
Outdoors on a bumpy road, the customer has to reduce the speed of the wheelchair to maintain the
control of the power chair. By activating the Road compensation, the user no longer has to reduce the speed
of the wheelchair themselves on an uneven road but the wheelchair itself will automatically adjust to the situation.
This means that the user can stabilize his global position by keeping the Multi Joystick with his chin at the
maximum throw on rugged terrain without losing control of the power chair.
When the wheelchair reaches a better surface, it speeds up again according to the improvement of the road.
When on a flat road, the power chair will reach very smoothly its highest speed again.

An ALS patient cannot maintain the same position in the chair for a long time. Muscle weakness and
fatigue causes him to lose his position in the chair and to sink with his chin below the top of the joystick.
This means that the position of the joystick must be easily adjustable during the day.
A customized curved rod, bended with a bending tool and equipped with 2 bolts with handles makes it possible
to adjust continuously the position of the joystick.

A Multi Swing, combined with a multi joystick, mounted on an individually adapted rod with permanent
adjustable bolts and controlled with a continuously pivotable and adjustable Twister switch with triple action
offers the most functional and innovative chin control ever seen.
With the Configurator software it is possible to adjust the working of the mo-Vis devices according to the
users’ needs. Almost all settings of the different devices are fully adjustable.
