DizzyDx is a web-based platform created by a team of clinicians, Clinical Insights, to help physical therapists identify ailments based on symptoms related to dizziness. My involvement in this project consisted of user lead research to help influence design decisions for the final prototype.

The purpose of this study was to uncover users' experiences navigating the platform on both mobile and desktop during the high fidelity phase of the design process.

Client Goals

  • Gain actionable insights from user feedback to improve the prototype.

  • Uncover any navigation related pain points reported by participants to improve information architecture.

User Groups

  • Students

  • Physical Therapists

  • Instructors

Research Methods

This user research study consisted of 15 remote usability tests with all three user groups. Participants in the study were asked to provide information on sentiments, expectations, and experience while navigating the platform. Each user was asked to create a mock case study to discover the platform's recommendations based on a mock patient's reported symptoms.

Key Findings

Usability Issues

DizzyDx homepage on mobile interface.

From this study, the client obtained actionable insights from the participants that could help improve DizzyDx.  Participants struggled to find the right sections or categories to access specific information, leading to a sense of confusion. The website presented an overwhelming number of options, which caused decision paralysis and hindered users' ability to progress smoothly. Participants struggled to understand the context of certain pages or sections, as there was a lack of supporting information or cues to help them navigate or understand the purpose.

Good User Experiences

Participants reported an appreciation for plain language used for the navigation portion of the site. Users were also fond of supportive features, such as the cited works feature that provides scientific evidence to support the platform's diagnosis of patients.


From this study, we were able to make recommendations to the client based on the feedback provided by the participants. These recommendations included:

  • Revisit DizzyDx's information architecture by applying the feedback obtained from the study to the website's navigation.

  • Limit the amount of information displayed to users on one page by identifying MVP content and consolidating repeated content.

  • Include content descriptions where necessary so users know what to expect as they navigate the site.
