boycotts affected the participation of their respective athletes in the Games; Hayden went on to say that "President Obama continues to strongly support all of the U.S. athletes who will participate in the Paralympics and wishes them great success". IPC communications head Craig Spence reported prior to the Games that there were not any boycott efforts among athletes, and stated that although the organization would keep an eye on the situation in the Crimea, "we've obviously expressed our disappointment with what's going on in the political situation, but at the end of the day, we're not here to do politics. We're here to organize a sporting event." He went on to emphasize that the same level of security measures in place during the Olympics were in place during the Paralympics, ensuring that Sochi would be the "safest place" in the country during the Games. The Ukraine team still participated in the Games, but Valeriy Sushkevich, head of the country's National Paralympic Committee, warned that "if there is an escalation of the conflict, intervention on the territory of our country, God forbid the worst, we would not be able to stay here. We would go." Similarly to the Olympics, political protests and statements among athletes were forbidden during Paralympic events, although two major, symbolic protests by the Ukrainian team occurred during the Games. During the opening ceremonies, all but one of the country's 31 athletes declined to participate in the parade of nations. The country was represented solely by Nordic skier and flagbearer Mykailo Tkachenko, whose entrance was greeted with an ovation from the audience. Some Ukrainian medalists were seen covering their medal with their hand during ceremonies as another form of silent protest; Sushkevich stated that the covering was "a demonstration that aggression and the high ideals of Paralympic sports are incompatible."

The IPC found evidence that swapping of positive samples had occurred during the 2014 Winter Paralympics. On 7 August 2016, the International Paralympic Committee announced that it had suspended the Russian Paralympic Committee. The country was banned from the 2016
