Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating gait disorders in patients, particularly those with Parkinson's disease, lack accuracy and objectivity, often relying on subjective clinical assessments and not effectively addressing the unique challenges of gait impairment.
Innovation Solution
A hydrotherapy system incorporating a multispectral imaging evaluation method that captures images of gait-impaired individuals both on land and underwater, using a multispectral thermal imager and a static pressure hydrotherapy pool to provide objective and comprehensive gait analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional clinical assessment methods are used, then the evaluation process is simple and quick, but the accuracy and objectivity of gait parameter analysis deteriorates
Solution Approach 1:
The patent replaces subjective mechanical/clinical assessment with automated optical imaging systems. Multispectral cameras capture gait parameters objectively, substituting expert visual inspection with machine-based measurement that eliminates human subjectivity while maintaining operational simplicity through automated analysis algorithms.
Solution Approach 2:
The patent introduces an intermediary imaging system that mediates between the patient's gait and the evaluator. The multispectral camera acts as an intermediary device that captures objective data, transforming the direct observer-observed relationship into an indirect measurement process that preserves accuracy while simplifying the evaluator's task.
2Adaptability or versatility
If gait evaluation is performed only on solid ground, then the assessment covers normal walking conditions, but it fails to capture gait characteristics under different environmental conditions
Solution Approach 1:
The patent creates a universal evaluation system that functions across multiple environments (solid ground and underwater). The same imaging equipment and analysis methodology are applied in both settings, allowing the system to assess gait under diverse conditions without requiring separate specialized devices for each environment.
Solution Approach 2:
The patent adds the underwater dimension to the traditional terrestrial gait assessment. By evaluating patients in both air and water environments, the system captures gait characteristics across different physical dimensions and buoyancy conditions, providing more comprehensive data for diagnosing various types of gait disorders.
3Reliability
If subjective clinical assessment methods are used, then the evaluation process is straightforward, but the tolerance for errors increases
Solution Approach 1:
The patent implements feedback mechanisms where the imaging system continuously captures and analyzes gait parameters, providing objective data that can be compared across different time points and environments. This feedback loop eliminates the variability inherent in subjective assessment and provides reliable, repeatable measurements for clinical decision-making.

AI summary
An evaluation method for gait-impaired individuals, including freezing gait in Parkinson's disease, and a corresponding hydrostatic water therapy pool, is provided. A multispectral thermal imager is utilized to observe and record the multispectral images of COP (Center of Pressure) trajectories in both on-land and underwater scenarios on black walkways. These images, including far/near-infrared and visible light with gait temporal/spatial parameters, serve as references for analysis and interpretation by physical therapists and attending physicians. Additionally, a personalized hydrostatic water therapy pool rehabilitation program is provided in conjunction with the patient or elderly individual, establishing a correlation between the evaluation and training. This approach enhances the effectiveness of evaluation and analysis, reduces healthcare costs, mitigates psychological barriers related to fear of falling during exercise, and ultimately improves the health and quality of life for individuals with gait-impaired individuals.
