Above the knee amputees.
Having an amputation Above the Knee has always required a socket extending high up into the groin area. These sockets are most commonly made from unforgiving rigid materials with a fixed shape and volume. Unlike comfortable clothing, the socket can be a lot to deal with.
Groin pain occurs when the socket fit becomes loose. The thigh sinks deeper into the socket and the groin is pressed onto the hard surface. A common solution to this problem is to try adding socks (if your socket uses them) but this requires taking the prosthesis off, having the right socks available and putting it back on. It’s a lot of work for many and even then some discomfort may remain.
Sitting is challenging (especially on hard surfaces such as wooden chairs or toilet seats) . Hard sockets do not give or let the thigh flatten out normally. The socket pushes up into the belly and groin and therefore bending over to pick something off the floor is difficult.
When sitting, the Sail flattens and conforms to the seat, the thigh can splay more naturally. The socket stays low to the seat and does not impinge when bending over. The wearer can "feel" the seat and sitting comfort is greatly improved.
Adjusting the fit of conventional sockets can be very difficult. Many sockets require the wearer to remove the prosthesis and add or subtract socks to make changes. Not having the right socks or knowing precisely what to wear can be time consuming, frustrating and often ineffective.
The "CJ" socket easily allows the wearer to adjust for even significant volume changes by simply adjusting the Velcro straps while sitting. The prosthesis and shoes need not be removed. Multiple straps along the socket allow the wearer to make precise adjustments to match the instanteanous residual limb volume and ensure comfort.
Upper Extremity Amputees.
Upper Extremity prostheses have been hugely sucessful using "CJ" technology. Snap or magnetic electrodes are easily adapted to the socket and the bulky preamps and wires are built into the inside of the "sail".
The sockets are lighter, less restrictive and more comfortable than solid rigid or semi-rigid sockets.
The “CJ” Socket only uses hard rigid material for part of the socket while the remaineder is comprised of a cloth material, the "SAIL”. It feels and flexes more like clothing.
