of choice for most of the test in this chapter because it allows the easiest accessibility to all tested areas with minimal position changes and allow the easiest comparison to conventional peripheral nerve root and dermatome charts. however should the supine position not be an option an alternative position such as prone or side lying is acceptable, sensation cannot be adequately tested through clothing so the areas of skin to be tested should be exposed but in a way that the patient's modesty is maintained reposition of the patient during testing should be kept at a minimum.
