Design takeaway

Designers should consider activity-specific prosthetic enhancements that leverage biomechanical replication and intuitive control interfaces to improve user independence and performance.

How to apply

When designing assistive devices, consider how to replicate natural human movements for specific, demanding tasks and integrate intuitive feedback mechanisms.

Project actions

01Consider a specific user group and a challenging activity for your design project.
02Explore sensor technologies for intuitive control of your design.
03Think about how to provide feedback to the user to improve their interaction with the product.

Method & Evidence

AimCan an active prosthetic ankle, controlled via EMG and servo motor, improve control and safety for lower limb amputees during motorcycle riding?

MethodProsthetic Design and Prototyping

ProcedureA prosthetic ankle prototype was developed incorporating a servo motor for active movement, a microcontroller for processing, and EMG sensors to detect user muscle signals. A remote control system was integrated onto the motorcycle handlebar for user operation. The system was designed to replicate natural ankle actions required for motorcycle control and provide haptic feedback.

Variables

IV["Presence of active prosthetic ankle","Type of control system (EMG vs. manual remote)"]

DV["Motorcycle control accuracy","Rider safety","User effort/fatigue","User satisfaction"]

CV["Type of motorcycle","Riding conditions","User's level of amputation","Prosthetic limb type (excluding ankle)"]

Strengths & Limitations

Strengths

+Addresses a significant unmet need for lower limb amputees.
+Integrates multiple advanced technologies (EMG, servo, microcontroller, haptics).
+Focuses on a specific, high-demand activity to demonstrate efficacy.

Limitations

The prototype might not fully replicate the complexity of natural ankle movement, and the EMG sensors may require calibration for individual users. The study's focus on motorcycle riding limits its generalizability.

Reliability & validity

Reliability could be assessed by repeated trials of the same task by the same user to check for consistent performance. Validity would be assessed by comparing the prosthetic's performance to that of a non-amputee rider or a rider with a standard prosthetic, and through user feedback surveys on control and safety.

Think critically

To what extent can active prosthetic components replace the full range of natural human biomechanics for diverse activities, and what are the trade-offs in terms of complexity, cost, and user adaptation?

Design Principles

"Activity-specific biomechanical replication through intuitive control interfaces enhances prosthetic functionality and user experience."

This research addresses a critical gap in prosthetic technology by focusing on a specific, high-demand activity. By replicating natural ankle biomechanics, designers can create prosthetics that not only restore function but also enhance user independence and social participation.

What This Means for Your Design

This study shows how a special prosthetic foot that can move like a real ankle, controlled by muscle signals and a motor, makes it easier and safer for people with leg amputations to ride motorcycles.
