Exploring Above Elbow Prosthetic Arm Options
For those undergoing an above elbow amputation, their quality of life can be significantly influenced by the type of prosthetic arm they choose. Understanding the available prosthetic options and how they align with individual needs is paramount. Broadly, there are three types of prosthetic arms: body-powered, myoelectric, and hybrid systems. Each type comes with its strengths and limitations, and the choice largely depends on the individual’s lifestyle, activity level, and personal preferences.
Body-Powered Prostheses
The simplicity and durability of body-powered transhumeral prosthesis have earned them recognition. They use a shoulder harness system, manipulated by body movements, to control a body-powered elbow and a myoelectric terminal device. This combination enables the user to pick up and grasp objects.
Although reliable, one downside to body-powered prostheses is that they may necessitate exaggerated movements and considerable energy input, which could result in fatigue and discomfort.
Myoelectric Prostheses
The functionality of myoelectric prostheses closely resembles natural movement. They operate by using small electric motors controlled by muscle signals from the remaining muscles. These signals are then translated into movement, allowing the user to perform tasks with greater ease. Myoelectric prostheses can provide increased grip strength, better adjustment to prosthesis usage, and successful execution of upper limb functional tasks.
Nevertheless, their steep price may pose a barrier to accessibility and affordability.
Hybrid Systems
Hybrid prosthetic arms meld the strengths of both the previously mentioned types. They combine the strength and control of myoelectric devices with the immediate feedback of body-powered systems, providing enhanced functionality. Hybrid prostheses enable the simultaneous control of multiple prosthetic components, making them particularly advantageous for individuals with extensive limb loss.
The Role of the Elbow Joint in Prosthetics
Despite often being overlooked, the elbow joint has a significant role in prosthetics, especially in cases of elbow limb loss. It mimics natural arm movement and provides stability, making it integral to the prosthetic arm’s function.
The elbow joint’s design and technology significantly influence user mobility and control of the prosthetic arm, contributing to a more natural movement.
Types of Elbow Joints
A variety of elbow joints, including stainless steel external elbow joints and automatic joints, can be integrated into above elbow prostheses. Each type of joint has its unique operating mechanism and offers different advantages.
For instance, polycentric elbow joints provide enhanced stability with their multiple pivot points, while hydraulic elbow joints use fluid pressure to regulate movement, providing a more seamless motion.
Achieving Natural Movement
Prosthetic elbow joints help users achieve natural movement and improve daily function. They simulate natural movement through locking, mimicking natural movement, or rotating 360 degrees. The mobility of the residual limb can also be leveraged for enhanced control.
With the right joint, users can experience:
- a more natural walking pattern
- simplified clothing management
- decreased requirement for trunk displacement
- the ability to transmit tactile sensations directly to the user’s natural bone structure.
Customizing Your Prosthetic Arm
Tailoring your prosthetic arm to your needs is a key step towards achieving comfort and functionality. From the inner socket design, which directly impacts the fit and comfort, to the suspension system that defines mobility, and the terminal device that interacts with the world, every element can be tailored to your specific needs and preferences.
Inner Socket Design
The design of the inner socket has a direct impact on the comfort and functionality of a prosthetic arm. Choosing between flexible or rigid materials, each offers different advantages. Flexible sockets provide comfort due to their soft texture, while rigid sockets offer stability and precise fitting.
With advancements in technology, there’s now the possibility to improve sweat absorption and channeling inside the socket liner.
Suspension Systems
Different suspension systems, including suction, self-suspending, and belt-based systems, offer varying benefits and drawbacks. Harness-based systems provide support and stability but require the user to possess the requisite strength and full range of motion.
Self-suspending systems offer suspension across the entire range of motion but may limit mobility at the proximal joint.
Terminal Devices
Acting as the interactive component of the prosthesis, terminal devices empower the amputee to carry out a range of tasks. They can be customized to accommodate individual needs, from prehensile devices for grasping and holding objects to specialized devices for recreational activities like photography or fishing.
Enhancing Control: Prosthesis Management Techniques
Control and functionality of your prosthetic arm can be improved with the application of effective prosthesis management techniques. Training plays a critical role in improving control and functionality, while external power sources provide the necessary energy for movement, thereby improving control over the prosthetic arm’s components.
Training with Your Prosthesis
To maximize control and independence in daily activities, training is indispensable. Exercises that focus on proper body mechanics, balanced posture, and strengthening residual muscles can assist in achieving more natural and intuitive movements. Moreover, adjusting the elbow rotation with friction devices and ensuring proper socket alignment can enhance control and load bearing.
Utilizing External Power Sources
The functionality of above elbow prosthetic arms can be greatly enhanced by external power sources like electric motors. They provide the energy required to move the elbow, wrist, and fingers, reducing the necessity for harnessing and allowing the prosthesis to function without direct input from the amputee.
