Methods and equipment

The Human Physiology Lab (Humanlab) provides a broad range of methods for invasive and non-invasive assessment of human physiological function, with particular depth in skeletal muscle and cardiovascular physiology.

A person does a work test on a test bike. The person has a breathing mask for gas analysis and ECG electrodes attached to them. A test supervisor monitors the test and looks at a screen showing different curves of the test.

The methods and equipment available at the lab are listed below, grouped by type of measurement. Neurophysiological measurements are carried out together with ME Clinical Neurophysiology.

  • Cardiopulmonary exercise testing 
  • Echocardiography
  • Vascular ultrasound
  • Static and dynamic spirometry
  • Magnetic resonance imaging 

Carried out in collaboration with the Department of Molecular Medicine and Surgery

  • Cardiovascular magnetic resonance (CMR) for cardiac structure and function
  • 4D flow MRI for blood flow and haemodynamics
  • Isokinetic dynamometry (Biodex)
  • Handgrip dynamometry
  • Force and power assessment, including force platforms
  • Muscle architecture by ultrasound
  • Body composition by MRI

Carried out in collaboration with ME Clinical Neurophysiology.

  • Needle and surface electromyography (EMG), including high-density EMG
