Touch Screen Test Fixture for Neurological Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating neurological and cognitive function, such as the Kurtzke Expanded Disability Scale and Multiple Sclerosis Functional Composite, are not precise, quantitative, and often require manual, subjective, and infrequent assessments, limiting their usefulness outside clinical settings and for longitudinal comparisons.
Innovation Solution
A system and method utilizing a computing device with a touch screen interface and a test fixture that allows for self-administered tests, including manual dexterity, cognitive processing speed, and movement assessment tests, using sensors like accelerometers and gyroscopes to collect data objectively and frequently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual neurological assessment methods (EDSS, MSFC) are used, then clinical evaluation can be performed, but the assessment lacks precision, objectivity, and frequency
Solution Approach 1:
The patent replaces manual mechanical assessment methods with an automated computing device system that uses sensors (accelerometers, gyroscopes, touch screens) to objectively measure neurological function. This substitution eliminates subjectivity in manual ratings while providing precise, quantifiable data through electronic sensing and processing.
2Productivity
If trained examiners administer tests, then accurate neurological assessment is achieved, but the testing process becomes infrequent and limited to clinical settings
Solution Approach 1:
The patent enables patients to self-administer neurological tests using a portable computing device without requiring trained examiners. The system guides patients through assessments via touch screen interfaces and automatically collects data through integrated sensors, making frequent testing accessible outside clinical settings while maintaining assessment quality.
3Loss of information
If quantitative assessment data is collected, then objective measurement is achieved, but data collection and storage requirements increase
Solution Approach 1:
The patent combines data collection, storage, and processing functions into an integrated computing device system. Sensors capture neurological data, the touch screen interface manages user interaction and instructions, and the device's memory and processing capabilities handle data storage and analysis, eliminating the need for separate manual data management processes.

AI summary
This disclosure relates to a device to mechanically and electrically connect with a touch screen computing device, such as a tablet computer. The device can include a platform that can be moved into and out of physical contact with a surface of a touch screen. During engagement with the surface, the moveable platform electrically interacts with the touch screen (e.g., via capacitive coupling) to enable detection by the touch screen of contact members (e.g., pegs) even in the absence of user contact with the pegs.
