Microneurography - LEG

The overall goal of the research is to record the signals arising from the receptors in the muscles of the lower leg. The microneurography technique involves placing a very thin needle electrode (diameter = 0.2 mm, tip diameter 0.005 mm) in the area of the sciatic nerve (on the back of the thigh) and record signals from single nerve fibers. We also record activity of the muscles in your left lower leg, through 8 surface electrodes (which are attached to the skin with double sticky tape).
In order to register the position of the foot and forces which are used during the task, a wooden plate is mounted on the foot (it is attached with Velcro straps).

You will be lying on your stomach on a bunk, watching a screen which is placed on the floor. Via position sensors on your foot you control a cursor on the screen and your task will be to play a simple game using your foot.

Duration of the experiment is approximately 6 hours. You will be reimbursed with 150 SEK for each commenced hour. The compensation is taxable.

There are no risks with participation.
A successful microneurography requires that participants do not experience discomfort. When we are searching for the nerve, some people experience temporary discomfort which disappears when the electrode is placed in the nerve. If the participant continues to experience discomfort, the experiment will be canceled immediately.

To be considered as a participant, you must be between 18-35 years, neurologically healthy, have normal movement patterns and no stiffness or discomfort from the back and the neck area and be ready to lie still for a longer time.
Height: 160 cm - 185 cm.
Maximum circumference of the thigh is 49 cm (measured about seven cm above the knee joint)

Date: ONE time, Weekday, 9am-3pm. Ongoing during Mars to June 2019.
