Identification of clinically related requirements of a novel assistive device for people with a high spinal cord injury

PLoS ONE, 2019 · DOI: https://doi.org/10.1371/journal.pone.0218393 · Published: June 28, 2019

Simple Explanation

The MAMEM project aims to create a device that helps people with spinal cord injuries use computers more easily. It uses eye tracking and brain waves to control computer functions. Researchers gathered information from a review of existing studies, a focus group of healthcare professionals, and questionnaires completed by people with spinal cord injuries to define the requirements of the device. This approach helps to organize and prioritize what the device needs to do, ensuring it meets the actual needs of its users and is as effective as possible.

Study Duration

Not specified

Participants

23 individuals with SCI (C5 and above)

Evidence Level

Not specified

Key Findings

1
The study identified 29 requirements for assistive technologies, categorized into performance, personalization, interoperability, usability, and physiology.
2
Enabling computer use in different body positions is an important requirement.
3
A key finding was the importance of privacy and security for users when accessing personal information, such as bank accounts.

Research Summary

This paper describes a method used to gather information on the needs of assistive devices from potential users with SCI, clinicians, and existing research. The study identified 29 requirements for new ATCCs, categorized by performance, personalization, interoperability, usability, and physiology, that are critical for effective device design. The three-pronged approach, incorporating literature review, focus groups, and questionnaires, ensures comprehensive data collection and helps overcome the limitations of individual methods.

Practical Implications

Device Design

Assistive devices should be designed considering the specific needs and preferences of individuals with high SCI, particularly regarding computer use.

Clinical Practice

Healthcare professionals should involve end-users in the planning and selection of assistive technologies to improve adoption and satisfaction.

Future Research

Further studies should adopt a similar three-way method to enhance the design and testing of new ATCCs.

Study Limitations

1
The generalizability of the questionnaires used in the present study was limited, since they were not tested for reliability and validity.
2
The convenience sampling method also limited the representativeness of outcomes.
3
The single meeting and small number of pre-selected members might have limited the scope of extracted requirements.
