Motion Laboratory

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.

Instrumented treadmill (Motek M-Gait) is installed into lab, in the capture volume of Vicon motion capture system.  The treadmill enables integration of motion analysis with physi.logical measurements, such as sprirometry and ECG.

Surface electromyography (EMG) can be combined to motion analysis. The newest equiment for recording EMG is  Delsys Trigno. Laboratory has a 14-channel Trigno system, which is integrated with motion capture system. Delsys Trigno is wireless and features dry electrodes integrated in one box. Thus only one box, size of a match box is enough to measure activity of a muscle. Boxes contain also IMU for orientation measurement

Alternatively a 16-channel data logger ME6000 (Bittium, Kuopio, Finland) can be used to collect EMG. Furthemore,  wireless Faros devices (Bittium) are available for EMG measurement outside the laboratory In addition to EMG, accelerometers, inclinometers and goniometers can be used with ME6000 data logger.

Two ultrasound devices: Telemed EchoBlaster 128 CEXT with sensor LV7.5/60/128-Z-2  and  Telemed LS128 with sensor HL9.0/60/128Z belong 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 wearable motion capture system (Xsens Awinda) enables motion capture in field for ergonomics and sports applications. System consists of 18 inertial measurement units (IMUs). The wearable system has been used to study ergonomics in cleaning work and in healthcare work. The system has been used for ski jump motion analysis with Finnish ski jumping team. Measurements have been carried out in ski jumping hills in Kuopio.

Take-off technique of elite ski jumpers is examined in laboratory using motion capture system and force plates. In addition musculoskeletal modeling and simulation is used to get deeper understanding on takeoff technique. Co-operation with  Ski Jumping Team Finland, Mika Kojonkoski's "Team China" and with Puijon Hiihtoseura ski club has been done.

Analysis of force-velocity-power properties of athletes has been started in ice hockey and volleyball. In addition, muscle activitivity of professional ice hockey players has been analysed. One master's thesis work on ice hockey players' muscle activity during skating has been published.

In collaboration with Kuopion alueen urheiluakatemia several pilot tests have been done. Optimization of paratriathlete Liisa Lilja's prosthesis length by using instrumented treadmill and breath gas analyzer has been one successfull pilot.

Trajectories of reflective markers are capture using motion capture cameras, and the force platforms
The instrumented treadmill (Motek M-gait) enables biomechanical analysis of continuous walking and running.

By combining measurement data with musculoskeletal modeling knee contact forces are computed in OpenSim platform.
