Summary
Researchers reviewed methods for measuring embodiment in prosthetic limbs. Understanding ownership, body representation, and agency is key for developing better neuroprosthetics and understanding embodied cognition.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Rehabilitation Science
Background:
- Advancements in neural interfaces for prosthetics enable exploration of embodiment.
- Neuroprosthetics research necessitates reliable measures of embodiment (ownership, body representation, agency).
- Standardized measures are crucial for generalizable experiments and technology comparison.
Purpose of the Study:
- To review and categorize existing outcome measures for evaluating embodiment in prosthetic limb users.
- To analyze the strengths and weaknesses of current embodiment assessment methods.
- To guide researchers and developers in selecting appropriate metrics for their studies.
Main Methods:
- Systematic literature review of outcome measures for prosthetic limb embodiment.
- Categorization of measures based on psychometric properties (e.g., reliability, validity) and type (behavioral, physiological).
- Critical analysis of the efficacy and limitations of identified measures.
Main Results:
- Identified and categorized various behavioral and physiological measures assessing ownership, body representation, and agency.
- Highlighted the psychometric properties, advantages, and disadvantages of each measure.
- Provided a framework for understanding and selecting embodiment metrics.
Conclusions:
- Effective measurement of embodiment is vital for advancing prosthetic limb technology.
- Selecting appropriate outcome measures enhances experimental rigor and facilitates technology development.
- Improved embodiment assessment contributes to a deeper understanding of human embodiment and agency.
