Study Arms (2)

Traditional Training Group

PLACEBO COMPARATOR

These subjects will be offered multimodal training. This will be comprised of demonstration by suitably trained individuals of relevant anatomy using pre-existing cadaveric samples, performing ultrasound scans of the relevant areas on volunteers under expert supervision, and the practice of needle insertion under ultrasound-guidance using commonly used tissue phantoms (turkey breasts).

Other: Traditional training

Simulation Training Group

ACTIVE COMPARATOR

In addition to traditional training the SG group will participate in a period of simulator based training. Following initial familiarization with the simulator these participants will identify relevant structures and follow their course in the virtual arm. They will insert a virtual needle into the virtual environment and advance it using an in-plane technique towards various target structures. They will be given immediate directed computer generated feedback and offered the opportunity for repetitive, deliberate practice. The simulator, which these participants will use, will comprise of a PHANTOM Desktop (http://www.sensable.com/), an haptic immersive workbench and the H3D API (http://www.sensegraphics.se/). The SG subject will scan and perform procedure specific tasks on a virtual arm. Training will continue until they reach proficiency levels set by experts using the same simulator.
