In January 2016 I released an online survey with the intent of determining whether shoulder injury rates differed among whitewater kayakers who used bent shaft or straight shaft paddles. Shoulder injuries are incredibly prevalent with whitewater paddlers, and I was personally interested in the data since I sustained multiple subluxations while kayaking ultimately resulting in surgery in 2012.

Many kayakers must have had a similar level of interest in the survey since there were over 2,700 responses. I fully expected less than 100 responses, but the survey truly went viral. Thanks for providing that data and rallying to spread the survey around! Unfortunately there are many confounding factors present, and I never had the time or technical skill to do justice to the sheer amount of data collected in the survey. I'd like to say I could put aside time for a project like this, but I'll be starting medical school next week and I don't think it's going to happen. Thus I'm making the raw data public so that people can sift through it if they're interested.
