Presentation
Discovering Acceptable Injection Force Through Magnitude Estimation and Force Profiles
DescriptionTopic: Discovering acceptable injection force through magnitude estimation and force profiles
Application: For medical device manufacturers to learn different techniques and best practices for determining acceptable force as defined by the user.
Background: Assessing the force output and acceptability of force can help inform bench testing procedures, and therefore create a better product for users. This is especially true for products with unconventional injection sites (e.g., ocular), multiple repeated injections, unique devices, and/or user groups with special force capabilities (e.g., people with Parkinsons, seniors, or people with arthritis). In order to improve patient safety, effectiveness, user comfort, and fatigue, it is not enough to only measure force output, but it is also necessary to understand how the force is perceived by the user. To optimize user comfort and control, medical device companies can measure a combination of force output and perceived force. This presentation will review methods and best practices for these measurements.
Overview of Presentation: This talk will address best practices and lessons learned when capturing force output alongside perceived force measurements, such as magnitude estimation, Likert scales, and the Borg rating of perceived exertion. The following topics will be further defined and discussed during the talk.
1. Background on when to capture force in human factors research.
a. Situations where measuring force is crucial to build better and safer products
i. Collecting data to understand the tradeoffs between force, comfort, and control.
b. Situations where measuring force is less worthwhile.
2. Making a custom device for capturing force output and considerations.
a. Pros and cons of different force sensors.
b. Building 3d printed jigs to attach a force sensor to injection devices.
c. Additional considerations for measuring force, including preparation, calibration, and data capture.
3. Measuring perceived force and when to use different measurements.
a. The advantages/disadvantages of magnitude estimation.
b. The advantages/disadvantages of Likert scales.
c. The advantages/disadvantages of Borg scales.
d. When to use multiple measures.
4. How to analyze force output data alongside perceived force.
a. Considerations for data analysis.
b. How perceived measures add to force output data.
5. Making sense of the data and using data to improve injection devices to meet user needs.
