A primary consideration in upper-limb rehabilitation is determining a patient’s suitability for a myoelectric prosthesis. Traditionally, successful myoelectric control requires a residual limb with specific characteristics, particularly strong and isolated electromyographic (EMG) signals. The Vulcan Myoband provides an alternative approach to myoelectric control. By utilizing a flexible, wireless Vulcan Myoband instead of standard rigid socket electrodes, the system is designed to accommodate a broader range of anatomical conditions and signal presentations. The Vulcan system is applicable for multiple upper-limb amputation levels. It is currently indicated for patients undergoing rehabilitation for: Clinical Note: The Vulcan Myoband and prosthetic hand system are not currently indicated for partial hand or individual finger amputations. Residual Limb and EMG Signal Considerations  In patients with complex residual limb conditions, identifying stable signal locations can be difficult and may require repeated calibration. Myoband addresses this challenge through high-sensitivity EMG sensors distributed around the forearm, as well as a smart algorithm developed by Vulcan, allowing the system to capture muscle activity from several channels simultaneously and reliably. This approach can improve signal detection reliability in patients with less predictable signal patterns, allowing it to adapt to various anatomical presentations where traditional single-site electrodes often fail. 1. Scar Tissue and Skin Grafts Scar tissue typically exhibits high electrical resistance, which can attenuate EMG signals and impede detection by standard single-point sensors. The Vulcan Control Solution: If localized scar tissue causes signal attenuation at one site, the algorithm relies on data acquired from adjacent sensors to capture the overall muscle activation pattern. 2. Bone Overgrowth and Irregular Contours Rigid electrodes require flat, continuous contact with the skin. Irregular stump shapes or bony protrusions can cause pressure points, discomfort, and inconsistent sensor contact (motion artifacts). The Vulcan Control Solution: Vulcan Myoband uses a flexible, modular elastic structure. This design allows the sensors to conform to the limb’s natural contours, maintaining contact without applying localized pressure on prominent bones. 3. Bilateral Amputations Clinical Case 3 – Bilateral Amputations [ Watch the video here] Extreme difficulty for the patient to don/doff devices and perform daily calibrations independently. The Vulcan Solution: The band design allows patients to slide the device on using their other stump. Software profiles are saved per limb, making synchronized bilateral control intuitive. 4. Osseointegration  Requires a system that doesn’t interfere with the percutaneous implant site while maintaining high-fidelity control. The Vulcan Solution: Since the bone is fixed, muscle movement is more predictable. Myoband captures these stable muscle contractions non-invasively, providing a high-speed interface that matches the direct-to-bone stability. For clinicians and orthotists, utilizing Vulcan Myoband approach simplifies the socket fabrication process by removing embedded wiring. Functionally, it provides a viable control option for patients whose signal patterns or anatomical features previously excluded them from using standard myoelectric systems.

The Vulcan Myoband is a wearable biosignal sensor designed to detect electromyographic (EMG) signals generated when muscles contract. These signals are then used to control a myoelectric or bionic prosthetic hand through Bluetooth Low Energy (BLE). In simple terms, the Myoband acts as the control interface between the patient’s muscles and the prosthetic hand, translating muscle activity into movement. Unlike traditional prosthetic systems that place electrodes inside the socket, the Myoband is worn as a sensor band around the upper arm, typically over the biceps. This design allows the system to capture muscle signals without relying on precise electrode placement within the prosthetic socket. How Does It Work for Patients? 1. Detecting Muscle Signals When a patient attempts to move their missing hand, the remaining muscles in the arm still generate EMG signals. The Myoband contains EMG sensors + IMU sensor positioned around the arm to detect muscle activity from different areas. This multi-point sensing approach helps the system capture weak or complex signals that may be difficult to detect with conventional electrode setups.

During calibration which typically takes less than one minute, the system analyzes the patient’s EMG signals and automatically determines two key levels: the muscle contraction threshold and the muscle relaxation threshold.  The Myoband’s built-in system automatically measures and analyzes patient EMG signals, calculating and establishing activation thresholds that adapt to each individual’s muscle strength, even in patients with weak or variable EMG signals. 3. Translating Signals Into Movement After calibration, the Vulcan prosthetic hand responds directly to the patient’s muscle activity through BLE communication. In the Vulcan system, the Myoband functions as the signal acquisition and processing unit, while the prosthetic hand acts as the execution device. After muscle activity is detected and translated into control commands, the Myoband sends these commands wirelessly to the prosthetic hand in real time. For example: Depending on the configuration, the control logic can also be reversed. This wireless control solution removes the need for complex internal wiring inside the prosthetic socket. As a result, clinicians have greater flexibility during socket fabrication, while patients benefit from a lighter system, easier maintenance, and more stable signal transmission during daily movement.

After an upper-limb amputation, receiving a myoelectric prosthetic hand can take one to six months, even after insurance approval or out-of-pocket agreement. The fitting process alone typically requires three to four clinic visits, depending on the complexity of the limb condition and the fabrication workflow. Yet despite this time and effort, myoelectric fittings still fail in many clinics. So why does fitting still take so long? Several factors commonly slow down the process: The EMG Signal Challenge Myoelectric prosthetic control relies on electromyographic (EMG) signals, which are generated when residual muscles contract. After an upperlimb amputation, the remaining muscles in the forearm or upper arm can still produce these signals when a patient attempts to move the missing limb. However, the characteristics of these signals vary widely from patient to patient. The biology of the residual limb and the original surgical procedure play a major role in determining how usable these signals are for prosthetic control. Several factors influence EMG signal quality, including: In addition, surgical reconstruction can alter the natural structure of the muscle system. Depending on the procedure, residual muscles may be reattached to bone or tendon, which can change how neuromuscular signals are generated and transmitted. As a result, EMG signals in an amputated limb often differ from those in an intact limb. They typically show: Surface EMG sensors must detect these signals through several biological layers, including muscle tissue, connective tissue, subcutaneous fat, and skin, which further attenuate and filter the electrical activity. Because of these physiological factors, sensor placement becomes critical. Clinicians must identify the most active muscle regions and optimize electrode placement based on signal amplitude, soft tissue thickness, and stability within the prosthetic socket. Why Electrode Placement Is So Difficult Most traditional myoelectric systems requiring electrodes to be placed on two opposing muscle groups. For reliable detection, electrodes must be positioned precisely on the muscle belly and aligned with the direction of the muscle fibers. During fitting, prosthetists often ask patients to perform repeated muscle contractions while adjusting electrode locations to find signals that are both strong and distinguishable. In practice, this process can involve extensive repositioning and testing, sometimes referred to clinically as “myosite hunting.” Even when optimal placement is achieved in the clinic, maintaining stable signals in daily life remains challenging. Factors such as electrode displacement, socket pressure changes, sweat, and natural biological changes in the residual limb can all affect signal quality. Socket Limitations In conventional prosthetic systems, electrodes are typically embedded inside the socket, which creates additional constraints. Socket design must balance structural strength, comfort, and space for electronic components. At the same time, electrode locations become fixed once the socket is fabricated. However, residual limb volume can fluctuate throughout the day, and small shifts in socket position during daily movement can alter electrode alignment. When signal quality changes, patients may require re-adjustments or even a new socket, extending the fitting timeline and sometimes leading to frustration or abandonment of the prosthesis. The Result: A Trial-and-Error Process Because EMG signals vary between individuals and depend heavily on precise electrode placement, the fitting process often becomes iterative and time-consuming. Multiple adjustments, test fittings, and recalibrations may be needed before achieving stable control. For patients eager to regain independence, these delays can be discouraging. For clinicians, they represent one of the most persistent challenges in modern myoelectric prosthetic care. How the Vulcan Myoband Addresses Common EMG Signal Detection Challenges Reliable EMG signal detection remains one of the most common challenges in myoelectric prosthetic control. In clinical practice, obtaining stable signals can be difficult, especially for patients with complex residual limb conditions. Supporting Patients With Weak or Complex EMG Signals The challenge: Many patients struggle to produce strong, clearly separated EMG signals due to factors such as: The Vulcan Solution: Instead of requiring strong or highly isolated contractions, the Myoband detects subtle increases in muscle activation above the resting state to establish basic open-close control of the prosthetic hand, based on a threshold recognition technology. As a result, patients may experience: Scar tissue, thick subcutaneous fat, or skin grafts, common in burn or trauma patients, can weaken EMG signals, making it difficult to identify two reliable muscle sites for traditional dual-electrode control on the residual limb. The Myoband overcomes this by being worn around the upper arm and using multiple sensors to capture overall muscle activation across a wider area. Even if one region produces weaker muscle signals due to scarring or reduced sensitivity, the system can still detect activity from surrounding healthy muscle tissue. Reduced Dependence on Precise Electrode Placement The Challenge: Traditional myoelectric systems often require precise electrode placement over specific muscle sites. Small positional changes can significantly affect signal quality. The Vulcan Solution: The Myoband reduces this dependency through multi-channel EMG sensing distributed around the upper arm, capturing signals from several muscle regions simultaneously. This design offers several practical advantages: Stability During Daily Movement The Challenge: During everyday activities, prosthetic sockets may shift slightly on the residual limb, a phenomenon known as pistoning. When electrodes are embedded inside the socket, this movement can disrupt signal detection. The Vulcan Solution: Because the Myoband is worn directly on the arm, the sensors maintain more stable contact with the skin.  The Myoband also integrates an IMU (Inertial Measurement Unit) that detects arm position and orientation. This helps distinguish between intentional muscle activation and postural contractions. For example: The system is also designed to handle environmental factors such as sweat and changes in skin impedance, using adaptive algorithms that maintain stable activation thresholds and reduce unintended hand movements.

When discussing control methods for prosthetics, it’s essential to differentiate between brain waves and muscle signals.  Brain waves are electrical impulses from the brain that can indicate thoughts or intentions to control the prosthetic hand. However, the Vulcan myoelectric hand does not use these waves for control.  In this blog, we will clarify how the Vulcan hand works, focusing on its simple control methods for every user to use. Why Does the Vulcan Hand Not Use Brain-Controlling Waves? Instead of relying on brain waves, the Vulcan hand uses muscle signals.  When a user thinks about moving their arm, the muscles from the bicep of their residual limb contract. These contractions create electrical signals that the Vulcan Myoband (the controlling sensor) can detect. Later on, Myoband will interpret these signals into a closing or opening statement to the Vulcan hand.  This method is more straightforward for users, making it easier to control the prosthetic. Importance of Muscle Signals in Making Control Intuitive and Effective Difficulty in use is one of the common reasons contributing to prosthetic abandonment for arm amputees according to Engdahl, 2015. This can lead to passive use of the device or total rejection, even just a few weeks after installing the prosthetic.  That is why a simple controlling method that can be learned and used quickly by most arm amputees is what Vulcan heads to from the beginning In the hope of minimizing the prosthetic abandonment for users. As Vulcan’s users become familiar with how their muscles respond, they can learn to control the prosthetic hand effectively in the shortest time (maximum of 30 minutes to learn on their fitting days).  This connection between thought and action makes it simpler for users to perform everyday tasks. Also, this approach of Vulcan makes it easy for users of all ages to operate, keeps costs reasonable, and does not require any plasty operation while still performing over 30 activities at a precision level.  All are done while being compact, easy to wear, and detachable for users of most ages, supporting them in regaining independence in their daily activities.  If you are interested in experiencing the Vulcan prosthetic arm or have any questions, please don’t hesitate to contact us by registering for this form. Our team is here to support you in less than 48 hours.

What is TMR Operations? Stump arrangement surgery, often known as Targeted Muscle Reinnervation (TMR), is a surgical procedure designed to improve the control and functionality of prosthetic hands for individuals who have undergone limb amputation.  The technique involves rerouting nerves that once controlled the amputated limb to the remaining muscles in the area, ensuring a better fit for a prosthetic arm.  While this can create a more stable base for certain prosthetics, it also poses several challenges.  How the Vulcan Prosthetic Hand Works Without Any TMR Required However, upper limb amputees do not need to experience these additional operations once they wear the Vulcan Prosthetic Hand. How can we make that difference?  Vulcan Myoband – Solution For No Surgery, No Pain One of our standout features is the Vulcan Myoband – the controller worn on the bicep of users.  With its highly sensitive ability, the Vulcan Myoband can detect muscle signals from the remaining part of the arm. Then adjust it to the suitable movements to control the prosthetic hand without any surgical intervention. Plus, the Myoband can be fitted to more than 90% of types of stump conditions, regardless of causes of amputation, age, nerve affected, scars amount, etc. Therefore, opening more opportunities to a wide range of upper limb amputees in the world.  Advantages of Using the Vulcan Hand Overall, this non-invasive approach means that users can start using the Vulcan hand as soon as possible and offering the following benefits: By eliminating the need for surgical stump arrangements, the Vulcan hand not only reduces physical risks but also addresses emotional concerns.
