Japan's Shingo Kunieda and Diede de Groot from The Netherlands have won the men's and women's titles respectively, while Australia's Dylan Alcott took the quads award.

Thirty-four-year-old Kunieda picks up the men's award for the eighth time, having first won it more than a decade ago in 2007.

He was victorious once again this year after wins at both the US and French Opens and a strong all-round performance on the Wheelchair Tennis Tour.

"I am really happy to be ITF world champion for the eighth time in my career, especially after battling with an elbow injury in recent years," he said.

"I am so proud but such an accolade does not happen without my team and supporters and I thank them wholeheartedly."

Kunieda has won 22 Grand Slam titles throughout his career, though he is still yet to win Wimbledon, having lost in the quarter-finals this year to Gustavo Fernandez from Argentina.

De Groot won the women's award for the first time after an incredible season saw the 21-year-old win eight of the 12 Tour tournaments she entered.

Within that winning run were three Grand Slam titles at the Australian Open, US Open and Wimbledon.

She also picked up doubles titles at the French Open, US Open and Wimbledon.

"It's been a crazy year for me," she said.

"It's great to have such incredible results after training so hard."

Alcott won only the second quads world title, beating the inaugural winner David Wagner from the United States.

Twenty-eight-year-old Alcott claimed the top spot thanks to wins at both the Australian and US Opens.

He called the season "memorable".

The ITF does not hold a World Championship tournament, instead crowning champions based on their performances in the calendar year.
