The research team found that left long arm thumb spica splints were the most detrimental to performance, with participants’ cone-penalized time increasing on average by 22.2 seconds (p < 0.001) compared to controls. Left short arm splints were the second most detrimental, with average increases of 16.2 seconds (p = 0.007).
“This is a best-case scenario,” said Dr. Lee. “These were trained drivers who had no pain. They didn’t have a fracture or an injury. They had been driving on this course for several weeks. Nonetheless, they had difficulty with immobilization. If we extended the results to the general population, and to drivers who may be in pain as well as immobilized, we can assume that they would perform worse.”
