Short answer

Designers must actively involve end-users (therapists in this case) throughout the development lifecycle to ensure products are intuitive, efficient, and meet real-world operational needs.

Field: User-Centred Design
Source: University of Salford Institutional Repository (University of Salford) (2015)
Method: Iterative, mixed-methods usability engineering approach.
Sample: 1 physiotherapist and 6 patients (total of 24 visits).
Evidence: Strong effect

Incorporating therapist feedback throughout the iterative design process significantly reduces the time required to set up functional electrical stimulation (FES) systems for upper limb rehabilitation. This user-centred design research insight is drawn from a 2015 study published in University of Salford Institutional Repository (University of Salford). Using Iterative, mixed-methods usability engineering approach. with 1 physiotherapist and 6 patients (total of 24 visits)., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must actively involve end-users (therapists in this case) throughout the development lifecycle to ensure products are intuitive, efficient, and meet real-world operational needs.

Therapist involvement in FES rehabilitation tech design halves setup time

University of Salford Institutional Repository (University of Salford) · 2015

Key Findings

01A novel FES system (UL FES Rehab Tool) was developed with a focus on therapist usability.
02Iterative design involving therapists led to a more efficient system setup.
03A model was devised to predict FES setup time based on therapist involvement.

Application

Design takeaway

Designers must actively involve end-users (therapists in this case) throughout the development lifecycle to ensure products are intuitive, efficient, and meet real-world operational needs.

How to apply

When designing any product that requires setup or operation by a specific professional group, conduct early and frequent user testing with members of that group.

Project actions

01Identify your primary user group early on.
02Plan for multiple iterations of prototyping and testing with your target users.

Method & Evidence

AimTo design and evaluate a user-friendly Functional Electrical Stimulation (FES) system for upper limb rehabilitation, focusing on therapist efficiency and patient needs.

MethodIterative, mixed-methods usability engineering approach.

ProcedureThe study involved five phases: identifying therapist requirements, user walkthroughs with expert and novice users, rapid prototyping with healthy participants, and usability testing of the software and hardware with a physiotherapist and stroke patients in both lab and clinical settings. A model to predict setup time was also developed.

Sample1 physiotherapist and 6 patients (total of 24 visits).

ContextRehabilitation technology for stroke patients with upper limb impairment.

Variables

IVInvolvement of therapists in the design process.

DVSystem setup time.

CVComplexity of the FES system, patient's condition (for clinical testing).

Strengths & Limitations

Strengths

+Inclusion of both lab and clinical settings.
+Iterative design process with user feedback.

Limitations

Your user group might be limited (e.g., only friends), and your testing environment might not be realistic.

Reliability & validity

Reliability could be improved by increasing the number of participants and standardizing the testing environment. Validity is strong as the study directly measures usability in a relevant context.

Think critically

How might the 'expert' vs. 'novice' user feedback differ, and how should a designer balance these potentially conflicting needs?

Design Principles

"Involve end-users iteratively throughout the design process to optimize usability and efficiency."

This highlights the critical role of user-centred design (UCD) in developing effective and practical assistive technologies. For design, it demonstrates how understanding user needs and workflows directly impacts product usability and adoption, especially in specialized fields like healthcare.

What This Means for Your Design

If you want to make a tool for someone to use, ask them how they would use it and test it with them as you build it. This makes it much easier and faster for them to use later.

How to use in your project

1.Use this as evidence for the importance of user testing in your design process.
2.Justify your UCD approach by referencing the benefits shown in this study (e.g., reduced setup time, improved functionality).
