So in the last month, I’ve had not one but two separate opportunities to experience a much faster route from saddle to ground.
My involuntary dismounts have both been on the same side of the horse, and ended with my landing (I believe) on the same parts of my body- that is, my right shoulder and hip. This last gravity check did a real number on my shoulder especially, particularly affecting the rotator cuff (so the masseuse told me as she dug her thumbs into the flesh there).
Even though I feel as though it was not my head that was the primary victim of these apparent nose-dives, I still wonder- what goes into the ‘fall to the head = new helmet’ rule? I have no evidence that my head was not involved at all, and admit that my neck was sore after the last incident, but obviously not concussion to my knowledge.
At some point, do we assume that the helmet has been compromised by the sheer association (like being stuck on my head) with my body as it hit the ground? Or does it need to take a more direct hit in order to be compromised? What is the rule you keep to? Does anyone know the exact science??
