For people with upper limb loss, choosing the right prosthetic is a life-changing decision. Some prosthetics use myoelectric technology, which responds to muscle signals, while others rely on body-powered mechanisms, controlled by shoulder or arm movement. Each system has its own strengths, but what if you could combine the best of both?
Hybrid upper limb prosthetics do exactly that. By merging myoelectric and body-powered functions, they provide greater control, flexibility, and reliability. These advanced prosthetics allow users to switch between different modes, making daily tasks easier and more intuitive. Whether it’s lifting a heavy object or performing delicate movements, a hybrid prosthetic adapts to the user’s needs.
How Hybrid Upper Limb Prosthetics Work
Hybrid prosthetic systems combine the strengths of both myoelectric and body-powered technology to offer a more versatile and responsive experience.
Instead of relying entirely on one method of control, they integrate both systems, allowing the user to choose the most efficient way to move their prosthetic hand based on the task at hand.
This flexibility makes them ideal for individuals who need both precision and strength in their daily activities.
The Role of Myoelectric Control
Myoelectric prosthetics function by detecting electrical signals from the user’s residual muscles. When a person thinks about moving their missing hand, the muscles in their residual limb still contract.
These small electrical signals are picked up by electrodes placed inside the prosthetic socket, which then send commands to the motors in the artificial hand.
This allows for smooth and natural movements without the need for excessive force or external harnesses.
One of the key benefits of myoelectric control is the ability to perform fine motor tasks. Actions like picking up small objects, holding a pen, or using a touchscreen require subtle finger movements that a myoelectric system can handle with ease.
By integrating artificial intelligence and machine learning, modern myoelectric prosthetics can even adapt to a user’s unique muscle signals over time, making control feel more intuitive.
The Strength of Body-Powered Systems
While myoelectric technology offers precision, body-powered prosthetics excel in strength and durability. These prosthetics use a harness and cable system, where movements of the shoulder, back, or elbow generate the force needed to open or close the artificial hand.
Because body-powered systems do not rely on batteries or electrical components, they are highly reliable and function well in rugged conditions.
The mechanical design of body-powered systems also allows users to exert more force when gripping objects.
For physically demanding tasks such as carrying groceries, holding onto railings, or using tools, body-powered control provides a stronger and more immediate response than myoelectric options.
Since the movement is generated directly by the user’s body, the response time is nearly instantaneous.
The Integration of Both Systems in a Hybrid Prosthetic
A hybrid prosthetic allows users to switch between myoelectric and body-powered control, giving them the best of both worlds.
Some models use myoelectric signals for fine motor tasks while activating a body-powered system for gripping and lifting heavier objects.
This means a user can perform delicate actions with precision while still having the strength to handle physically demanding activities.
Hybrid systems also improve energy efficiency. Myoelectric prosthetics rely on batteries, which can drain quickly with heavy use.
By incorporating body-powered elements, hybrid prosthetics reduce power consumption, ensuring that the prosthetic remains functional for longer periods without needing to recharge.
Another major advantage is the added reliability. If a battery runs out or an electronic component malfunctions, the user can still rely on the body-powered system to control their prosthetic.
This provides a level of security, especially in environments where recharging a myoelectric device is not always convenient.
The Benefits of Hybrid Upper Limb Prosthetics
Hybrid prosthetics are designed to provide users with more control, adaptability, and comfort than single-mode prosthetics.
By integrating both myoelectric and body-powered systems, these devices offer a seamless experience that enhances everyday functionality.
The combination of these two control methods makes hybrid prosthetics a preferred choice for individuals looking for both strength and precision in their artificial hand.
Greater Versatility in Everyday Tasks
One of the biggest advantages of hybrid prosthetics is their ability to adapt to different situations. Users can switch between myoelectric and body-powered control depending on the task.
If a person needs to perform delicate activities, such as typing on a keyboard or buttoning a shirt, the myoelectric system allows for precise, small movements.
For tasks requiring more force, such as lifting objects or gripping something firmly, the body-powered system provides the necessary strength without draining battery power.
This adaptability is particularly useful in professional settings where users may need to perform a wide range of actions throughout the day.
A person working in an office might use the myoelectric function for tasks like writing, while relying on the body-powered system for physically demanding activities like carrying heavy files or operating machinery.
The ability to alternate between these two modes ensures that the prosthetic does not limit the user’s work or lifestyle.
Reduced Fatigue and Increased Efficiency
Using a prosthetic all day can be tiring, especially if it relies on a single control system. Myoelectric prosthetics, while advanced, require constant muscle contractions to generate signals, which can lead to muscle fatigue over time.
Similarly, body-powered prosthetics demand physical effort from the shoulder or back, which can become exhausting if used for extended periods. Hybrid systems help reduce strain by allowing users to balance their energy expenditure.
When one system becomes tiring, they can switch to the other, ensuring longer and more comfortable use throughout the day. This balance not only enhances endurance but also minimizes discomfort, making hybrid prosthetics a practical choice for individuals who require prolonged use.
Enhanced Reliability and Backup Functionality
One of the major concerns with fully electronic prosthetics is their dependence on battery life. If the battery runs out, the device becomes non-functional until recharged. A hybrid prosthetic eliminates this issue by providing a body-powered backup.
Even if the myoelectric system fails or the battery depletes, the user can continue using their prosthetic with the body-powered control. This feature is particularly beneficial for people who work in environments where recharging may not always be possible, such as construction sites, outdoor jobs, or rural areas.
The assurance that the prosthetic will continue to function under any circumstance gives users peace of mind, making them less dependent on technology failures.
Improved Durability and Cost-Effectiveness
Myoelectric prosthetics rely on motors, sensors, and electronic components, which can be vulnerable to wear and tear. Body-powered systems, on the other hand, use mechanical cables and harnesses that are rugged and long-lasting.
By combining both technologies, hybrid prosthetics reduce the overall strain on delicate electronic components, increasing the lifespan of the device.
Hybrid prosthetics also reduce long-term maintenance costs. Since the body-powered system does not rely on complex electronics, repairs are often simpler and more affordable.
This makes them a cost-effective solution for individuals looking for a prosthetic that balances advanced technology with practical durability.
Who Can Benefit the Most from Hybrid Upper Limb Prosthetics?
Hybrid prosthetic systems offer a unique blend of control and flexibility, making them suitable for a wide range of users.

This will make the transition between body-powered and myoelectric control even smoother, requiring less effort from the user.
Machine learning algorithms will also enhance grip functionality. Instead of manually switching between different grip patterns, future hybrid prosthetics could predict the type of grip needed based on past movements.
For example, if a user frequently picks up a coffee cup in the morning, the prosthetic could automatically prepare the correct grip without requiring extra effort.
Integration of Haptic Feedback for a Sense of Touch
A major limitation of current prosthetic systems is the lack of sensory feedback. While myoelectric and body-powered hands allow for movement, they do not provide a sense of touch. This makes it difficult for users to gauge how much pressure they are applying when holding objects, sometimes leading to accidental drops or an overly tight grip.
Scientists are developing haptic feedback systems that use sensors in the prosthetic fingers to send signals back to the nervous system. This means users will eventually be able to feel textures, pressure, and even temperature variations.
By combining haptic feedback with hybrid control, prosthetics will not only move like a natural hand but also provide a more intuitive sensory experience.
