Ergonomics Suite Version 2.0

The BioGraph Infiniti Ergonomics Suite lets you record 2-10 channels of SEMG for biofeedback or research, using any one of four Thought Technology encoders: FlexComp Infiniti, ProComp Infiniti, ProComp+ or ProComp2.

Record and save raw SEMG at 2048 sample/second or RMS SEMG at 256 samples/second, along with force and goniometry adapters. After recording, you can replay and review your SEMG raw data (RMS, Raw, Median Frequency and Spectral),on any one of over 100 display screens. Each specialized display screen offers a world of choice for clinical and research including complete statistics that can be viewed and reviewed in real time. Video from one web camera can be displayed with the measures being recorded, to show muscle activity synchronized with movement.

Ergonomics for the FlexComp Infiniti

Ergonomics for the FlexComp Infiniti has 6 channel sets and 40 screens for flexible and reliable multi-channel SEMG recording. The 6 channel sets give you the power to connect up to 10 MyoScan-Flex sensors for SEMG recording or a combination of 6 MyoScan-Flex sensors and 4 single-axis goniometers, 5 force sensor adapters, a single goniometer and 1 twin-axis goniometer with 5 force sensors, 6 MyoScan-Flex with 2 force sensor adapters and 2 goniometer adapters, 10 force sensor adapters, or 10 single-axis goniometer adapters.

The Ergonomics suite provides general positioning and specific screens for back, arm and leg placements of 6 channels of SEMG, 2 goniometers and 2 force.

A second series includes screens for left, right and both hands, displaying color changes and digital readings corresponding to pressure at each fingertip. In addition, the suite includes screens for the placement of a twin-axis goniometer at the wrist to measure extension/flexion and abduction/adduction, a single-axis goniometer at the elbow to measure flexion, and the use of a torsiometer to measure pronation/ supination.

These screens show readings from SEMG sensors to record muscle activity at placements determined by the user. In addition, the screen below shows 2 Channels SEMG and Force and Goniometer.

Ergonomics for the ProComp Infiniti

Ergonomics for the ProComp Infiniti includes 7 channel sets and 38 screens for multi-channel raw and RMS SEMG, combined with force sensors, goniometers and torsiometers.

The 7 channel sets are as follows: 6 SEMG and 2 goniometers for legs, 4 goniometers for legs, 5 force and 3 goniometers or 5 force or 4 SEMG, 2 Goniometers and 2 force or 8 channels of force calibration and a channel set for 8 channels of goniometer calibration. Goniometers and Torsiometers are interchangeable in the software. The screens offer a variety of ways of displaying and measuring SEMG, gonimeter/torsiometer and force including: single and multi line graphs for SEMG, gonoimeter/torsiometer and force, scales for force, animations as well as dual screens displaying linegraphs on one and video on the other. In addition, tonal feedback and color changes are used in various screens to indicate change or threshold crossings.

There are a number of screens for arms, wrists, hands, knees and legs indicating force or goniometer/torsiometer sensor placement to measure extension/flexion and abduction/adduction, displaying the angle in degrees and video to show actual movement in correlation with the values. A graphic display of the hand is used to indicate where the force sensors should be placed with corresponding statistics for the total force of the hand with the Max, Min, and Mean values for the force of each finger displayed from the linear transform algorithm. This enables the user to calibrate and set the unit of measures for each sensor. A variety of review screens with linegraphs with statistics are also included to easily evaluate the client's performance.

The screen below is for 6 channel SEMG leg evaluation, indicating electrode placements and providing a digital display of the corresponding RMS signals. This screen can be used with others in the leg series, loading up to 5 screens at a time, to provide an integrated view of the leg as a whole.

The screen below is for four channel goniometer evaluation, focusing on the angle of the knee and ankle. Placement is on the back of the knee and the outside of the ankle. This screen can be used with others in the legs series, loading up to 5 screens at a time, to provide an integrated view of the leg as a whole.

Ergonomics for the ProComp+

Ergonomics for the ProComp+ encoder includes 7 channel sets and 38 screens for 6 or 4 channels of SEMG and Goniometer and/or Force. Each of the 7 different channel sets allows for a different use of the ProComp+.

The first 2 channel sets in the suite allow you to calibrate the goniometers, force sensors or torsiometers. The third channel set is for monitoring dual leg activity and angle and a fourth channel set is for using 4 goniometer channels (i.e. for angle measurement of the knee and ankle). There are 3 other channel sets: one for 5 channels of force, another for 5 channels of force with 3 goniometers, and a general channel set for 4 SEMG RMS channels, with 2 force sensors and 2 goniometers.

A series of screens are designed for the arm and hand.

Another example shows the graphic of an object (hammer) and the placement of force sensors for each finger and the thumb. Force displayed at each tip from a linear transform algorithm, enables the user to calibrate and set the units of measure for each sensor.

Ergonomics for the ProComp2

Ergonomics for the ProComp2 provides you with 2 channel sets and 31 screens for you to use with 1 and 2-channel SEMG applications that use the ProComp2 with 1, or 2 SEMG, force, goniometer or torsiometer sensors in various combinations. Goniometer screens provide speed, acceleration, min and max of the signal in digital displays and line graphs.

A sequence of screens shows a graphic of right and left wrist with the placement of dual axis goniometer to measure extension/flexion and abduction/adduction. The user can calibrate and set the units of measure for each sensor combined with video to show actual movement in correlation with the goniometer measures.

3D animation of right and left wrist goniometer placements assist in setting up sensor connections.
