Universal
biofeedback trainer UBT200 |
 |
This console allows the setting of goals and the provision of a reward when the set goal
is achieved. A goal is set by specifying the
required amplitude and duration of an input modality, such as grip force or joint angle. A reward is specified in terms of units of time in
which an electric device such as a toy or radio is activated. The current amplitude of the input modality as
well as the accumulated reward in seconds are displayed.
An interface and software package is available for the IBM PC for display and record
keeping.

Hand
Function Trainer
|
 |
The hand function trainer is a device designed to facilitate therapeutic training in
hand-eye coordination, finger dexterity and motor function.
The device has sixteen screw holes arranged in a 4 by 4 layout. There is an LED
associated with each screw hole. Upon
completion of a screw-in task, the LED will be turned on and a beep sound will
be provided to indicate a successful task. An
audio feedback in different tone will be played when all sixteen screws were screwed
in-place. The trainer comes with four
different sizes of circular knobs (10 in, 16 in, 26 in. and 56 in. diameter). The system is battery powered using two size D
batteries.

Circular range of motion trainers for upper limb |
 |
16 push-buttons are used to form a circle with a diameter of approx. 27inch. There is a red-indicator light associated with
each push button.
When a light turns on, the user has to press the corresponding button for an audio REWARD. If the button is not pushed after a pre-set length
of time, a discouraging sound is produced as a punishment.
The lights can be selected to turn on one after another in three ways: clockwise, counter-
clockwise or at random. The audio volume and
the speed at which the lights run are adjustable.
The lights are grouped in 4 consecutive quadrants. Each group can be selected or de-selected. This
feature is necessary for users with a limited range of motion.

FEPS switch
assembly
|
 |
This assembly has a steel shaft. At one end
of the shaft is fixed a rod which will activate one micro-switch when the shaft is rotated
clock-wise and another micro-switch when it is rotated counter-clockwise. The resistance to rotation is adjustable and the
two micro-switches can be positioned from 30 deg. to 330 deg. apart in 15 deg. steps. Another two switches are activated by pushing and
pulling the shaft.
A number of actuators can be attached on the other end
of the shaft. These are:
Knobs: 1 inch, 1-1/2 inch, 2-1/2 inch,
3-1/2 inch dia.
Discs: 1inch, 2-1/4 inch, 3-1/4 inch,
4-1/2 inch dia.
Rods : 3/4 inch, 1 inch (1-1/2 inch dia., 5 inch long)
Motor skills required to activate the switches are flexion, extension, pronation and
supination (FEPS).

Upper limb strength trainer
|
 |
Developed to increase upper extremity strength and endurance. This versatile exercise unit is fully adjustable
in its inclination angle. Resistance can be
adjusted by adding 1 kg. weights. Audio
feedback is provided to indicate the tempo of exercise.
The electronic console monitors the number of cycles completed and the elapsed
time.
The therapist can either set the number of cycles to complete or the length of exercise
time in seconds. Therefore, a training
session can either monitor the length of time it takes to complete a given number of
cycles or the number of completed cycles in a given length of time.
A version with an additional, mid-mounted vertical handle is available.

6 position,
flat plate, programmable ROM trainer for lower limb |
 |
This trainer has six foot-pedals each with an associated red indicator. The indicators will either light up in a random
sequence or in a programmed sequence of up to 48 steps.
The sequence can be programmed to either run at one of eight speeds or to follow
the speed of the user. A correct step within
the selected time will be rewarded by an encouraging tone.
A wrong step or failure to follow the indicator within the selected time will be
punished by a discouraging tone. A tune
will be played at the completion of a sequence.
A stand is available to incline the device at either 15 or 30 degrees.

6 position, angular, programmable ROM trainer for
lower limb |
 |
This device is developed to facilitate the training of lower extremity range of
motion. This biofeedback unit consists of six
switches, which can be programmed or randomly activated to train the range of motion of
the leg. Audio feedback in different tone is
provided upon each successful or unsuccessful switch activation within a pre-defined
period of time.

Lower limb
exercise monitor |
 |
This device facilitates exercise program of the lower limb.
The electronic console monitors the number of cycles of lower leg extension/flexion
completed and the elapsed time. Counting is
done using non-contact sensors. Resistance
can be added to the patient’s lower limb using sand bags of different weights (not
included).
The therapist can either set the number of cycles to complete or the length of exercise
time in seconds. Therefore, a training
session can either monitor the length of time it takes to complete a given number of
cycles or the number of completed cycles in a given length of time.

Gait training aid with tone/light for correct gait
|
 |
This device has a sports insole with two switches embedded in the region of the heel
and the 1st metatarsal head respectively.
The insole is inserted into the shoe of the user.
When the user moves his foot in the normal heel-first-toe-second sequence, a light
and a buzzer will be activated momentarily. The
light and sound serve as an indication of, as well as a reinforcement for correct foot
motion.
This device has a built-in accessory that converts it into a single-channel biofeedback
aid, such as drop-foot indictor.Gait training aid with two tones for heel-strike and
toe-off
This device uses the same insole for the device above.
Different tones are produced momentarily for either heel-strike and toe-off. The device can also be used as a dual-channel
biofeedback aid.

Weight bearing trainer |
 |
This device is developed to monitor weight bearing under the heel. It provides audio and visual feedback to indicate
whether the prescribed loading has been exceeded. The
threshold load when audio feedback signal occurs can be adjusted with the patient standing
on a set of bathroom scales.
