9E369 and 9E370 4-in-1 Controller LS

Provides proportional DMC control for the System 2000

Provides more clinical options to the practitioner and enhanced function to the amputee
Offers a broader range of applications
Meets the needs of the child as his/her abilities change or signals improve
Minimizes the need for extra space and or length in the prosthesis

The 4-in-1 Controller LS was designed to be used exclusively with the System 2000 Hand for Children.

The 9E369 fits size 5 hands; the 9E370 fits hand sizes 5½, 6 and 6½.

The 4-in-1 Controller LS offers a broader range of applications when fitting children with upper limb amputations, in particular those with long below-elbow residual limbs or wrist disarticulation amputations. It meets the needs of the child as his or her abilities change or signal improves. Function may be changed through the simple exchange of color-coded plugs.

Available in a low-profile housing designed to be installed between the inner and outer laminations, the controller minimizes the need for extra space and/or length in the prosthesis.

Color-coded plugs offer four different control options.

Dynamic Mode Control
for Children who have good muscle potential (30 µV or greater signal)
(green coding plug = left system hand / blue coding plug = right system hand)
Opening and closing of the Electrohand 2000 is controlled by two 13E125 Electrodes. Grip speed and grip force are determined by the level of the muscle signal. This provides a more natural gripping motion and control when handling small or fragile objects.

Dynamic Mode Control - Low Input
for children with lower muscle potential (20 µV or less).
(yellow coding plug = left system hand / violet coding plug = right system hand)
Unlike the conventional adult DMC control, maximum grip speed and grip force are achieved more quickly. Opening and closing of the Electrohand 2000 is controlled by two 13E125 Electrodes. The grip speed and grip force are controlled by the level of the muscle signal. This provides a more natural gripping motion and control when handling small or fragile objects.

Digital Control
for Children who have difficulty maintaining signal above minimum thresholds (10µV signal or greater)
(white coding plug = left system hand / red coding plug = right system hand)
Two 13E125 Electrodes control the opening and closing of the Electrohand 2000. When the 10 µV threshold is reached or exceeded, the Electrohand opens or closes with constant speed.

Electronic Voluntary Opening
for infants or for children who cannot differentiate between the muscle site, or for those who have only one good control site.
(orange coding plug = left system hand / black coding plug = right system hand)
A single 13E125 Electrode controls the opening of the Electrohand 2000. The stronger the muscle signal, the faster the Electrohand opens. Once the myo-signal ceases, the motor automatically closes the Electrohand. Grip force with the EVO can be adjusted on the circuit.
