Design outcomes

Primary

Measure	Time frame
Two different nerve catheters are located with the help of ultrasound. Each volunteer has to perform physiotherapeutic exercises hourly all together for 3 times. After these exercises the volunteer has to undergo an ultrasound examination to evaluate catheter postion. After 3 runs volunteers should do daily routine activities for 2hours. After this procedure a final ultrasound examination take place. The dislocation rate are evaluated.	—
