I guess what I'm saying right now is that if anyone else is frustrated with the lack of professionalism of your health care providers, I'm right there with you!
Aim,
I understand your point but do these people lack professionalism or are they just ignorant of our sport? Is your treatment different because you ride a motorcycle? If so, than that would be unprofessional. Healthcare providers of all types are taught prevention, behavior modification etc.. It is therefore prudent for them to suggest to you to cease in engaging in what they consider "high risk" activity. Right or wrong, don't sweat it, their motives are for the most part well intended.
In today's healthcare you are a consumer, therefore I would challenge you to seek out providers that have an understanding of sport mentality and provide you competent care. If you and your provider are not on the same page than find another. They are out there and probably more than you think. I understand your frustration but educating these providers so they can be informed of the unique demands of our sport will serve us all better than flaming them.
So here is what I would do. When you need rehab talk to fellow riders and find providers that understand the sport or at least work with athletes. Call local professional sport teams in your area and track down the M.D.'s, therapists, and trainers. They usually have a clinic often as part of a major hospital and they do see other clients beside the professional team. In fact the team contract serves as PR for attracting clientele to their clinic. State your rehab goals early and often to wart off a paternal lecture. Bring in a video for the healthcare provider who lacks understanding to let them see first hand what encompasses the sport . I have done this with colleagues and it works well. Inform them of the growing popularity of the sport of MX, in all its forms, and the need for greater understanding of the physical aspects that are involved as the injury rate is increasing rapidily. This may inspire them, although maybe not for the right reasons. Let them know that by continuing to ride you are offering them job security! :)
Good Luck from your biased healthcare professional and avid off-road rider, Keith :D
