The Eye Gouge Head also allows the user to practice striking an attacker’s ear replicating what is likely to cause a ruptured tympanic membrane (ear drum). When a cupped hand is struck against the outer ear, the resultant rush (over-pressure) of air into the middle ear can cause a tear (barotrauma) in the ear drum. The energy can also upset the “balance” bones in the inner ear. This can result in disorientation, vertigo and pain giving you a further chance to create a window of opportunity to re-assess, disengage or escalate dependant on the situation and your perception of risk.
Warning: All the following or above mentioned mentioned tactics are extremely injurious in the real world which is why all trainees must understand the legal ramifications of using violence to prevent or extricate themselves or others from an attack. All users should consult the governing criminal and civil laws applicable to “self defence” in their region (as well as other jurisdictions when visiting) and fully understand other options of social de-escalation and escape prior to having to use violence to defend themselves. Consult your agency subject mater experts (SMES’s) for your best practice tactics and techniques.
