Key Findings

• Virtual technology offers flexible and configurable rehabilitation control.
• It can be used both during hospital admissions and after discharge.
• Virtual technology presents a relatively low cost compared to traditional methods.
• It shows promise in overcoming critical barriers in current prosthetic training.

Research Evidence

Aim: To systematically review the application of virtual technology in prosthetic rehabilitation for upper limb amputees, focusing on usability, flexibility, psychological affinity, and affordability.

Method: Systematic Literature Review

Procedure: A systematic review was conducted following PRISMA, STROBE, and CASP guidelines, screening 22,609 articles and ultimately including 17 for analysis.

Context: Prosthetic rehabilitation for upper limb amputees

Design Principle

Design for adaptability and accessibility in rehabilitation technologies to maximize user engagement and functional recovery.

How to Apply

When designing rehabilitation tools, consider how virtual or augmented reality can simulate real-world tasks, provide immediate feedback, and allow for personalized training regimens that can be accessed remotely.

Limitations

Challenges remain in achieving high levels of realism, implementing robust closed-loop control, and integrating multi-modal feedback within virtual rehabilitation systems.

Student Guide (IB Design Technology)

Simple Explanation: Using computer simulations (like video games) for physical therapy can make it easier and cheaper for people who have lost an arm to learn how to use a prosthetic limb.

Why This Matters: This research shows that using technology like virtual reality can make rehabilitation more effective and accessible, which is important for designing products that help people improve their lives.

Critical Thinking: How can the identified challenges of realism, closed-loop control, and multi-modality integration be addressed in future virtual rehabilitation system designs to further enhance user experience and effectiveness?

IA-Ready Paragraph: This review highlights that virtual technology offers significant advantages in prosthetic rehabilitation for upper limb amputees, providing flexible, configurable, and cost-effective training solutions. The adaptability of these systems, allowing for use both in clinical settings and post-discharge, addresses a critical barrier to widespread prosthetic adoption and training.
