Supplementing all CAREN configurations, Motek Medical provides additional integrated components that further enhance the use of the system. These additional components consist of:
EMG
Including EMG (Electro-Myography) data via an analog integrator allows muscle activity to be incorporated into the feedback loop. Data can be acquired through the same interface as the force plates. Tethered or un-tethered systems are available on request.
Video Capture
The use of a video capture system provides a reference video feed to allow full replay of the trial or study. Systems from 2 to 6 cameras are available depending on requirement.
Tailored motion capture suits
Special developed motion capture suits that are convenient to wear for disabled subjects.
Data Gloves
The incorporation of data gloves into the system allows the integration of finger and hand movement into a study or program. Macro-movements of the hand are tracked by the optical system, so that the arc of movement of the arm as well as fingers can be used. Reaching, grasping and other upper limb studies can thus be instigated. With the possibility of collision detection, the patient can be given direct feedback regarding their relationship to an object.
Haptic systems
Haptic devices are integrated into the D-flow software, giving the subject force feedback regarding the actual resistance of the virtual object to touch. In some devices parameters like viscosity of the virtual materials is also integrated.
Energy Consumption System
Allow the measurement of gas exchange on a true breath by breath basis. This enables the exploration of physiological responses during trials. Physiological parameters like VO2, VCO2, Heart Rate and Ventilation can be measured.
Pressure measurement systems
In-Shoe or floor based measurement through the use of pressure pads can show centre of pressure as well as pressure distribution. In-shoe sensors allow the distribution to be seen through for instance a gait cycle and stepping.
Heart rate measurement systems
Data streaming from heart rate meters can be fed directly through the D-flow interface and also be used to affect the VR environment, serving as a decision parameter for the feedback loop control.
Head Mount Displays
Sometimes a more enclosed and intimate environment is required. Head mounted displays provide either stereoscopic images or a plain video display to the patient.
