Stroke is a common incident causing loss of limb function. Rehabilitation of upper limb function is currently labor intensive and due to limited resources rehabilitation outcomes are not optimal. On the other hand, robot arm technology is rapidly developing, so called collaborative robots can work safely in same space with humans. The group has acquired one of the leading collaborative robot, namely KUKA lbr iiwa.
Iiwa is used to develop wide range of applications for rehabilitation of upper limb function. Robot arm can perform repetitive tasks independently, thus reducing need for human work to perform efficient rehabilitation.
Virtual reality device HTC Vive can be used to create rehabilitation games and virtual environments where activities of daily living can be trained at the late stage of rehabilitation.
Motion capture system (Vicon Vero) with two floor-embedded force platforms (AMTI OR6-7). Force platform setup is modifiable, enabling measurement of ground reaction forces in various movements.
Surface electromyography (EMG) is often combined to motion analysis. A 16-channel data logger ME6000 (Bittium Inc, Kuopio, Finland) is used to collect EMG. Also wireless devices, eMotion WBA and Faros are available for EMG measurement, both from Bittium. In addition to EMG, accelerometers, inclinometers and goniometers can be used with ME6000 data logger.
Ultrasound device (Telemed EchoBlaster 128 CEXT) with sensor LV7.5/60/128-Z-2 is the latest addition to the equipment. Data collection of the device is synchronized with the motion capture system, enabling in vivo dynamics of muscles and tendons to be analyzed.
Whole body IMU-based motion capture system (18 IMUs, Xsens Awinda) enables motion capture in field conditions. This far IMU-based motion capture has been used to study ergonomics in cleaning work and in healthcare work.
The driving simulator is developed in-house. Realistic cabin is constructed on a motion platform and equipped with real pedals, gearshift and steering wheel with force feedback. Simulator software (SCANeR, Oktal) with latest updates is used to create realistic scenarios of various traffic situations. Surround sound system is used ensure immersive experience.
In the simulator enviroment various biosignals, such as EMG, ECG and galvanic skin response (GSR) can be measured. In addition, driver's eye movements can be tracked. Furthermore, thermal imaging can be used to detect temperature changes on driver's face.
By combining the measurements and experience of the group in signal analysis driver's physiological state can be monitored.
Equipment of the laboratory include ergo-spirometer (Ergoline), gas analyzer (Schiller), mobile spirometer (Cortex), strength training equipment, biosignal amplifier system (Biopac) and treadmill.
Bicycle ergometer is integrated with Schiller spirometer and mobile spirometer.
