Physiotherapy Dry Needling Accuracy

The goal of this clinical trial is to learn if the addition of cadaver review improves: * the accuracy of physiotherapists who practice dry needling. * the perceived safety of dry needling by physiotherapists. Researchers will compare the effects of an anatomy review using cadaver material to that of an educational intervention not related to anatomy to see if the anatomy review improves the needling accuracy and safety of physiotherapist who practice dry needling as compared to the control intervention of education not related to anatomy. Participants will: * Needle three muscles related to safety and/or accuracy using ultrasound imaging to gather accuracy and safety measurements. * Take an initial knowledge exam capturing their knowledge on needling safety. * Be randomized into a control group or intervention group. * The control group will receive an online educational session not related to anatomy. * The intervention group will receive a cadaver anatomy review class focused on high-risk area. * Re-take a knowledge exam after their course (either cadaver lab or on-line education) to capture any change. * Needle the same three muscles again using ultrasound to capture accuracy and safety measurements. If reviewing anatomy using cadaver materials improve physiotherapists needling accuracy and safety, then this educational intervention could be recommended to be added to dry needling course instruction.
