What side effects are associated with this type of intervention?

The most common treatments for amputation, particularly those involving pre-prosthetic training like the MyoTrain AR system, generally have minimal side effects. Augmented reality-based systems and myoelectric pattern recognition technologies are designed to enhance motor control and do not typically cause significant adverse effects. However, users may experience mild discomfort or fatigue from extended use of the system. Conventional motor imagery exercises, used as a control in the MyoTrain AR study, are also low-risk but may lead to mental fatigue or frustration if progress is slow. Overall, these pre-prosthetic training methods are considered safe with few reported side effects.

What prior FDA approvals exist?

There are no specific FDA-approved treatments directly comparable to the MyoTrain AR system for augmented reality-based pre-prosthetic training in amputees. However, there are various FDA-approved devices and therapies aimed at improving the quality of life for amputees, such as advanced prosthetic limbs and rehabilitation technologies. These include myoelectric prostheses, which use electrical signals from the residual limb muscles to control the prosthetic, and virtual reality systems for pain management and rehabilitation. These technologies aim to enhance motor control, sensory feedback, and overall functionality for amputees.

What other types of research exist?

Promising, novel alternatives to MyoTrain AR for amputation patients in 2024 include: 1) Virtual Reality (VR)-based rehabilitation systems, which provide immersive environments for motor imagery and control training. 2) Advanced myoelectric prostheses with integrated biofeedback systems that enhance user control and adaptability. 3) Brain-Computer Interface (BCI) technologies that allow direct neural control of prosthetic limbs, improving precision and response times. 4) Robotics-assisted rehabilitation devices that offer precise, repetitive motion training to enhance muscle memory and control stability.

Summary

This trial is testing a new training method called MyoTrain AR for people who have lost part of their arm below the elbow. The training uses augmented reality to help them practice controlling a future prosthetic arm. The goal is to see if this method helps them use their prosthetic arm better compared to traditional exercises.

Who is the study for?

This trial is for adults over 18 with a healed trans-radial amputation who are candidates for an advanced myoelectric prosthesis. They must speak English and have no prior experience with pattern recognition control, unhealed wounds, sensitive skin issues, significant cognitive or neurological deficits, or uncontrolled pain that could affect participation.

What is being tested?

The study compares the MyoTrain AR system's effectiveness against conventional motor imagery exercises in improving control stability of prosthetic devices. Participants will be randomly assigned to either continue standard care or use the new MyoTrain AR system before getting their prosthesis.

What are the potential side effects?

While not explicitly mentioned, potential side effects may include discomfort from wearing EMG electrodes for those with sensitive skin and possible frustration or fatigue during training sessions.

Experimental Treatment

Active Control

Group I: MyoTrain AR SystemExperimental Treatment1 Intervention

Participants will undergo functional task training using the MyoTrain AR system, which includes the HoloLens 2 augmented reality head-mounted display, four HTC VIVE SteamVR kinematic trackers, eight surface EMG electrodes based on the Element hardware platform, and a desktop computer. Participants will be prompted to use a pattern recognition-based myoelectric controller to operate a virtual prosthesis and complete a simulation of the GaMA Cup Transfer Task.

Group II: Conventional Motor ImageryActive Control1 Intervention

Participants will be provided motor imagery exercises that involve brief attempts to move the missing limb in a similar manner to how they would control their pattern recognition system to strengthen their muscles. These exercises do not involve any real-time control feedback or functional assessment.

Other Research

Common treatments for amputation, such as the MyoTrain AR system, utilize augmented reality (AR) and myoelectric pattern recognition to improve prosthetic control. AR creates an interactive environment for patients to practice motor skills, while myoelectric pattern recognition uses sensors to detect muscle activity in the residual limb to control the prosthesis. These technologies enhance the precision and stability of prosthetic movements, which is vital for amputation patients as it significantly improves their rehabilitation outcomes and daily functionality with the prosthetic device.
