Users' and therapists' perceptions of myoelectric multi-function upper limb prostheses with conventional and pattern...

Area of Science:

• Rehabilitation Engineering
• Prosthetics and Orthotics
• Human-Computer Interaction

Background:

• Multi-function myoelectric upper limb prostheses offer advanced capabilities compared to traditional devices.
• Understanding user and therapist perspectives is crucial for improving prosthetic technology and adoption.

Purpose of the Study:

• To explore and describe the opinions of prosthesis users and therapists regarding multi-function myoelectric upper limb prostheses.
• To compare user and therapist experiences with conventional control versus pattern recognition control systems.

Main Methods:

• A qualitative interview study was conducted with 15 prosthesis users and 7 therapists.
• Semi-structured interviews were analyzed using a thematic framework approach.

Main Results:

• Prosthesis users and therapists found multi-function prostheses more functional but rarely used them for active grasping.
• Dissatisfaction was expressed regarding mechanical robustness and conventional control switching.
• Pattern recognition control was valued for intuitive function switching but deemed unreliable for daily use, requiring extensive training.

Conclusions:

• While multi-function prostheses are perceived as more functional, significant challenges remain in their practical application and reliability.
• Improvements in mechanical robustness and control system reliability are needed to enhance user satisfaction and functional use.
