An investigation published on a Swiss website has shown that more and more International Sports Federations list disabled athletes than any other sportsmen or sportswomen. In 2006, the Extremity Games were formed for people with limb loss or limb difference to compete in extreme sports. College Park Industries, a manufacturer of prosthetic feet, organized this event to give amputee athletes a venue to compete in this increasingly popular sports genre also referred to as action sports. This annual event held in the summer in Orlando, includes competitions in skateboarding, wakeboarding, rock climbing, mountain biking, surfing, moto-x and kayaking.

By combining people with and without disabilities, S4EA hopes that participating athletes will interact and form lasting bonds of friendship through shared sports and recreational activities in S4EA's served communities. Although the organization's focus is primarily San Diego County, S4EA has grown from this base to satellite programs in Ventura and Temecula, California.

The Army Wounded Warrior Program offers sitting volleyball to injured service members, and some organizations also offer sport opportunities to family and friends of injured service members in addition to the members themselves. Two Paralympic-style multi-sport events exist exclusively for wounded, injured or sick armed services personnel and veterans: the Warrior Games in the United States and the Invictus Games which originated in the United Kingdom.
