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

Biodex System interfaced with Thought Technology’s Infiniti hardware and BioGraph Infiniti software

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

We also provide an off-the-shelf solution for interfacing isokinetic machines to our 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.
