Laboratory-based Motion Analysis

In our Motion Laboratory at Karolinska University Hospital, Solna, we offer laboratory-based analysis of movements, forces and muscle activity.

The lab-based motion analysis provides a detailed portrait of human movement. Besides the most commonly used setup focusing on walking and mobility, we also offer consultations on how the measurements could be adapted to best address the questions you intend to answer in your specific project. The Motion lab is equipped with the following:

Vicon Motion Cameras for 3D Motion Analysis

The Motion analysis lab is equipped with a 3D motion analysis system from Vicon, Oxford Metrics. Also known as Motion Capture, the system consists of 8 cameras emitting an infrared light that reflect on retroreflective markers placed on specific landmarks of the body or an object of interest.

kneebend test for artrosis on Kistler force plates

Kistler force plates 

Two force plates are installed in the lab floor. The force plates measure the ground reaction forces that take place during e.g. walking or knee-bending, registers the forces and torques acting on the joints, including postural sway. The force measurement systems detects even minor changes in gait pattern or gait asymmetry and shifts in center of gravity. Read more about Kistler force plates here

Noraxon EMG recording of muscle activity during weight lifting

Electromyography (EMG)

The lab is equipped with 10 wireless EMG transmitters (Noraxon) for measuring of muscle activity. Wireless EMG can capture an array of muscle groups to get a deeper and more defined information beyond motion/ video capture. Read more about Noraxon EMG here

Analysis of Pediatric Foot Deformities by Pedobarography

EMED Pedobarography

The lab is equipped with a pressure platform (4 sensors/cm2) for recording of forces and the foots pressure distribution in Pascal/Newton during dynamic walk. The platform is commonly used to assess Pediatric Foot Deformities, such as congenital talipes equinovarus (also known as clubfoot) or foot loading parameters in hallux valgus-feet.
