I'm guessing it is possible, there's been a bit of news about CTE among the jetski community, and it is apparently related to the impacts of going over waves and landing thereafter. So not about banging your nut on the jetski or similar, just the sharp change in direction as they land. This obvs happens a lot on a jetski, but the point is basically the same.
I've never had what you are describing from airtime in the park. But heavy landings are one reason I'm not that much a fan of really poppy take offs, cause they generally don't match the landing by being similarly steep, so they tend to be hard landings. For me, a kicker is poorly built if there is much, if any, significant impact when you land anywhere near the sweet spot. I remember doing a 25m kicker one season where the landing was like you'd only done a 2 or 3 foot air, and the sweet spot was knuckle to at least half way down the landing. That one was so well built that when I lost it a bit on the in-run cause of random skiers making small moguls on the in-run and my left binding half let go, I floated over the knuckle, landing flat on my back after a 25m plus flight and had no impact really worth talking about. This is how a jump should be built.
