Cognitive Test Workflow Adjustment for Motor Impairment Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cognitive tests administered on platforms like the Philips IntelliSpace Cognition (ISC) are often affected by motor impairments such as tremor, bradykinesia, or speech tremors, leading to inaccurate assessments of cognitive functioning, especially in neurodegenerative diseases like Parkinson's disease.
Innovation Solution
A computer-implemented method that automatically detects motor impairments during cognitive testing, adjusting the neuropsychological assessment workflow by generating recommendations to compensate for these impairments, including spectral analysis and Bayesian models to quantify impairment severity and adjust test scores or skip affected tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cognitive tests with motor components are administered to patients with motor impairments, then the assessment can be completed, but the test scores become inaccurate due to motor impairment rather than cognitive impairment
Solution Approach 1:
The system performs preliminary detection of motor impairments before administering cognitive tests. By detecting tremors, bradykinesia, or other motor symptoms in advance, the system can identify patients who may have inaccurate test results and adjust the assessment workflow accordingly, preventing unreliable data collection
Solution Approach 2:
The system continuously monitors motor performance during cognitive testing and provides real-time feedback. When motor impairments are detected during test administration, the system can alert clinicians, adjust test parameters, or modify the workflow to compensate for motor symptoms, ensuring more accurate cognitive assessment
2Measurement precision
If the neuropsychological assessment workflow is adjusted to compensate for motor impairments, then measurement accuracy improves, but system complexity increases
Solution Approach 1:
The system integrates multiple functions into a unified workflow management platform. The same system that administers cognitive tests also detects motor impairments, analyzes their impact on performance, and automatically adjusts the assessment protocol, eliminating the need for separate complex subsystems
Solution Approach 2:
The system automatically detects motor impairments and generates workflow adjustments without requiring manual clinical intervention. The automated detection and adjustment mechanisms reduce the burden on clinicians while maintaining measurement precision

AI summary
A method for adjustment of a cognitive testing routine in dependence upon detection of a motor impairment of the patient during performance of the cognitive testing routine. In particular, a workflow for administering a neuropsychological assessment which comprises one or more cognitive tests is adjusted in dependence upon detection of a motor impairment.
