Primary

MeasureTime frame
This study compares changes in muscle activity dynamics during exercise due to postural changes and the effects of electrical stimulation on movement with voluntary movement. Positron Emission Tomography (PET) using the glucose analog FDG allows investigation of skeletal muscle dynamics during low- to moderate-intensity exercise. The exercises include calf raises and low-intensity cycling, lasting approximately 30 minutes to ensure safety.
