Socket Suspension Systems
Much emphasis has been placed on computer aided technology over the last couple of years. While these advancements are important to the future of prosthetics, the key factor to patient satisfaction is comfort and suspension. Rehab Systems has helped develop some of the newest systems used to optimize the fit and comfort of the prosthetic, and with amputees on staff we are able to personally test different systems to find the optimal set up for individual patients.
Removable Rigid Dressing
The Removable Rigid Dressing is designed for use immediately after amputation. The removable rigid dressing helps protect the healing residual limb and provides mild compression to minimize edema. It is easily removed for wound inspection and dressing changes. The removable rigid dressing can be fit efficiently with little inconvenience or discomfort to the amputee.
Stable Flex/Air-Lock Transtibial Socket
From personal experience as an amputee, Dale Perkins, CPO has developed a new below-the-knee fitting method. It features a patented socket design which removes pressure from the patellar tendon and distributes it throughout the limb for increased comfort and knee motion. This system works in conjunction with an airtight locking mechanism co-designed by Rehab Systems which reduces movement within the socket. The Air-Lock provides a mechanical lock between the patient and the artificial limb, while its airtight feature maintains consistent hold on the limb without the pulling sensation on the bottom of the limb at the lock location.
Non-Invasive Transfemoral/Summit Lock Socket
Dale Perkins, CPO began to develop unique fitting techniques for above-the-knee amputees after the birth of his second son Matt, an AK amputee. A number of different techniques and components can be determined by the patient’s limb and preferences. One of the more recent techniques features a casting technique that allows the amputee to comfortably lay down while creating a mold using non-invasive methods. The fitting is done with a locking system called the Summit Lock (developed in part by Rehab Systems) along with a gel liner. These two components combine a good fitting "suction" system, with a back-up locking mechanism which also controls rotation. This results in optimal comfort and convenience and does not require space at the bottom of the limb, helping to maintain a correct knee center.
Vacuum Suspension Systems
Vacuum Suspension Systems are designed for amputees who have fleshy tissue and who need optimal stability. It works by rolling a gel liner on the limb and then donning the prosthesis and rolling a suspension sleeve over the top. A small vacuum pump draws all air out of the socket, thereby creating an intimate fit, and providing the patient with increased stability, increased proprioception and increased comfort.
Microprocessor knees are designed for above-knee-amputees who are active but need the added confidence of a stable knee. It works via a hydraulic cylinder. In addition, a computer chip controls the stability of the knee and how easily it bends. Thereby preventing any stumbles or trips if the foot catches on something. The patient is able to regain control and prevent a fall, a function not available in other knees.
Parial Foot Prosthesis
Increased off-loading of the foot and ankle. Fits inside most orthopedic and walking shoes. Gives support and strength to the end of foot. Custom, comfortable plastic interboot that improves gait. Allows most patients to walk on uneven surfaces including sand and uphill.
Myoelectric Upper Extremity
These prosthetics are designed for upper extremity amputees who have good muscle control and who are interested in both the cosmetic aspect as well as function that is most comparable to a human hand. The prosthetic works by way of myoelectric signals relayed from the muscles to electrodes. This transmission tells the hand to open or close, and can even grip objects, all with cosmetic appeal. Newer versions, including the I-Limb, feature five controllable fingers with superior sensitivity and control.
Upper Extremity Prosthetics
The options for upper extremity prosthetics have become almost overwhelming. Many options are now available for any activity an amputee may be interested in from weight lifting and golfing to fishing and cooking. Various tools and componentry allow for a wide range of daily activities, specialized sports and hobbies. The different terminal devices offer high strength solutions and durability for even the most aggressive user.
