We've all seen the shocking pictures from last week's European Championship time trial in the Netherlands, Stefan Küng bloodied and wearing a badly damaged helmet as he crossed the finish line.
It caused quite the discussion around safety, rider welfare, concussion and more, former UCI president Brian Cookson calling for a crackdown on the head down TT position, and retired pro Phil Gaimon recalling his own concussion experience, saying there is "nothing inspiring or bada** about" riding through a head injury and that riders need to "respect their brains".
And the incident also prompted the Swiss Cycling team to launch an internal debrief and the federation's manager to admit that they should have better protected their rider so he did not finish the race.
Well, now a doctor (and cyclist) has weighed in with his own professional views and personal experience of concussion from cycling. Writing on Twitter, Martin said he was happy to see more people talking about the issue and wants to stress to cyclists that "knocks are not to be trifled with"...
"I was discharged shortly after with zero symptoms of concussion. No headache, nausea, dizziness or amnesia. As far as I could tell, I wasn't unconscious after my crash. But I did recall stumbling a bit when trying to get off the ground. Not much, only a slight unbalanced step," his thread continued.
"Did my due diligence in resting over the weekend and returned to work in the emergency outpatient clinic next week. I didn't last a day before the headaches and nausea set in. My supervisor sent me home for the rest of the week.
"I returned the following week with only doing 80 per cent days and a stern message to work at my own pace. That is far slower than we usually do to keep the ward functioning. Just as well, because I had no chance of keeping the normal pace in the ER.
"For the next six months I realised what life is like for people who are troubled with headaches. They would come on whenever the pace at work got high, or with accumulated screen time or concentration. In half a year, these symptoms gradually faded.
"I was fortunate that my course of post-concussion symptoms were mild. Those knocks are not to be trifled with. Don't know how many patients I've seen with severe symptoms from not taking a blow to the head seriously enough.
