Extreme Knees For Winter Sport

Extreme Knees For Winter Sport

Winter is here and I though it would be good time to write about winter prosthetic sport options.  With a background in the ski industry having fit ski boots for the last 20 odd years, and now working with amputees who like to take part in winter sport i could not think of a more exciting time with all the emerging technology for extreme and winter sport.  This article will try and provide brief information on some of the extreme winter sport knees currently on the market.

This incredible “b-peg” prosthesis, which has been two years in the making and cost around €12,000 to build, came about when Zaal teamed up with mechanical designer and part-time snowboard instructor LiangTi Tan, who he met in 2008. Once they’d joined forces with Boers & Co, a business specialising in precision mechanics that agreed to sponsor the project, things really got underway.

What’s revolutionary about this particular snowboard prosthesis is the asymmetrical parallelogram that connects the knee with the ankle. In layman’s terms, this means that Zaal is able to keep his balance when snowboarding. Existing prostheses usually have a fixed ankle joint or one with limited movement, with the result that it’s very difficult to maintain balance when doing linked turns or carving – both pretty key manoeuvres for boarders to master.

“The first thing that comes to my mind when I think of snowboarding with the b-peg is the feeling that it’s not the prosthetic, but my own snowboarding skills that are holding me back,” Zaal says.

“That gives me a tremendous feeling of freedom.”

Tan has also integrated a Step-In system, allowing Zaal to both step into the board binding and take it off with minimal effort.
