The Voltage Isolator 4 Infiniti is an interface device which provides electrical isolation. It will allow Thought Technologys systems to be safely interfaced with analog outputs of line-powered systems, such as computers with DAC cards, isokinetic dynamometers, or force platforms.

The Voltage Isolator 4 is for use with the Thought Technology Procomp Infiniti or Flexcomp Infiniti platforms running version 5.0 of Infiniti or higher.

It comes with different input ranges (set at factory on demand, when ordered): 2.5V, 5V, 10V, 0 5V, 0 10V or 0 20V.

The Voltage Isolator makes it possible for interfacing isokinetic machines to the Infiniti systems.

Real-time physiology monitoring (such as SEMG, heart rate and respiration) is an important asset to the data provided by the isokinetic machine (position, torque and velocity). It provides the examiner physiological data to validate the effectiveness of the training and helps the examinee to modify their physiology (breathing patterns, muscle activation patterns…) in real time during the training.

Regarding SEMG, it allows the evaluation of the activity of muscles or muscle groups during the movement (contraction intensity, timing, sequence of firing and local muscle fatigue) and to correlate them to the phases of the exercise (isometric, isokinetic, isotonic, concentric or eccentric). SEMG biofeedback motivates the patient to play an active role in the rehabilitation process.

Supported Isokinetic Dynamometers:

• Biodex System 3 and 4
• BTE Primus
• CON-TREX LP, WS and MJ
• CSMI HUMAC NORM and CYBEX NORM
• LimbGym
