• AKA. Right Leg

• Riding for 4 years, after injury

• Regular Foot

• Stance: R +15°, L – 5°

 

Foot (photos: B1)

 

• Nicole rides on an Ossur VSP Flexfoot which is a moderate/high activity foot. The prosthetic foot is set close to a standard walking alignment with the pyramid system set about 3° to the back.

• Nicole prefers to use a Flexfoot that is rated for twice her own weight in order to get more performance out of the carbon spring while carving. She finds this foot to be particularly good for Alpine events like Slalom and GS. Unlike some other adaptive riders, she does not notice any torsional twisting in the shock unit. This could be due to her light weight.

Foot Wedge (photos: C1, C2)

 

• This wedge is a 2” heel lift created from a block of wood and is covered in duct tape to prevent damage to the snowboard boot.

• Please note: this wedge is used in conjunction with the middle hole setting on the bottom of the XT9 and the red aluminum wedge to mimic the proper knee and ankle flexion of an able-bodied stance. (please see below)

XT9 (photos: D1, D2)

 

• The XT9 prosthetic knee is designed by SymbiotechsUSA. Due to Nicole’s lighter weight and the wedges, the bottom bolt of the shock is set to the middle hole in the framework of the XT9. This placement also gives her greater spring response in the cut of a strong carve or when landing a jump. Please note the difference from the other XT9 users.

• This setting, along with the Trunion Mount (red part and screw dial on the shock), bolt setting, and wedges, mimics able-bodied ankle and knee flexion. This way of setting the XT9 gives consistent energy return for her needs.

Red Wedge (photos: E1)

 

• This aluminum stock wedge is a 3/8” lift; it is set between the XT9 and the male end of the pyramid alignment system. As stated above, this wedge competes the proper flexion and extension snowboard stance alignment.

Socket (photos: F1, F2)

 

• The socket is made of carbon fiber with a cosmetic foam cover. The rim of the socket has a low profile on the inner thigh which allows a little more movement while riding. It is good for doing a Nose Press.

• The socket also has small holes in the front and bottom that work in conjunction with the liner/KISS suspension system.

Socket Liner (photos: G1)

 

• The liner is silicone Ohio Willowwood model that creates suction to the residual limb and help prevent slippage. It also has the Velcro strip attached to the bottom, instead of a pin, to attached it to the prosthetic limb.

KISS (photos: H1, H2, H3, H4)

 

• The KISS system is a simple and effective way of securing the liner to the socket. It uses a two contact points and a weave of a Velcro strapping to secure the liner to the socket.

• The first point of contact is at the bottom of the liner. The Velcro strap slides through the bottom hole in the socket.

• The second point of contact is at the midpoint of the socket. A Velcro strap slides through the disc-like hole to fasten with the bottom strap. There is also a metal coin-like disc on the liner that fits snuggly into the top hole. This helps prevent torsional twisting while riding and can prevent injury.

• In between the socket, liner, and KISS system there is a strong bond created that is ideal for shredding down the mountain.
