| 2015 | Liao | SE | 12 | Short axis | Carpal tunnel inlet (proximal margin of the flexor retinaculum between the scaphoid and pisiform bones) | Standard deviations of the cumulative strain [SDCS] |
| 2014 | Miyamoto | SE | 31 | Short axis | Carpal tunnel inlet (scaphoidpisiform level) | AC/MN (Acoustic Coupler/Median Nerve) strain ratio |
| 2015 | Ogur | SE | 20 | Long axis | 4 different places: proximal carpal tunnel at the level of the pisiform, distal carpal tunnel at the level of the hamate, middle of the carpal tunnel, forearm area one centimeter the proximal carpal tunnel | |
| 2013 | Orman | SE | 41 | Short axis | Scafoid-pisiform level (no measure were taken at the hamate-trapezium level) | Ratio between median nerve and subcutaneous fat |
| 2014 | Yoshii | SE | 15 healthy volunteers | Short axis | Parallel to the wrist crease (proximal carpal tunnel) | Ratio between median nerve and coupler |
