Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therefore, before clinical application, we wish to measure the repeatability and reproducibility of Young's modulus of intraneural and extraneural tissue in volunteers. For measurement, a region of interest (ROI) will be selected over the appropriate nerve and adjacent tissue. The ROI results will be regarded as paired data. Paired data will be measured over and adjacent to the interscalene C5 nerve root, infraclavicular lateral cord, musculocutaneous, median, femoral, saphenous and sciatic nerves.
