Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The healthcare industry, particularly small and large healthcare practices, faces challenges in automating physical therapy management, leading to inconsistent patient adherence to exercise regimens, which can hinder recovery and increase healthcare costs due to reduced outcomes and potential need for surgical revisions.
Innovation Solution
An automated physical therapy management system that includes a motion sensor worn by patients during exercises, communicating with a user computing device and a healthcare facility device, to track and record performance data, providing real-time feedback, and sending logged information to healthcare practitioners for monitoring and guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If patients perform physical therapy exercises at home without automated monitoring, then the system complexity is low, but patient adherence and performance consistency deteriorate
Solution Approach 1:
The motion sensor and computing device work together to automatically monitor, track, and record patient exercise performance without requiring manual intervention. The system self-manages data collection, analysis, and feedback provision, thereby improving patient adherence monitoring while keeping the overall system relatively simple and easy to implement.
2Measurement precision
If manual monitoring of patient exercise performance is used, then the system complexity is low, but measurement precision and reliability of performance data deteriorate
Solution Approach 1:
The patent replaces manual monitoring methods with an automated motion sensor-based system. The motion sensor objectively measures exercise parameters such as range of motion, repetitions, and exercise quality, providing precise and reliable performance data without the subjectivity and inconsistency of manual observation. This substitution maintains low system complexity while dramatically improving measurement precision.
3Reliability
If automated motion sensing is implemented, then patient performance tracking accuracy is improved, but device complexity increases
Solution Approach 1:
The motion sensor serves multiple functions: it detects motion during exercises, tracks performance parameters, and provides data for both patient feedback and practitioner monitoring. The wireless communication interface enables the same sensor to function in both home monitoring and clinic integration scenarios. This multi-functionality improves reliability while minimizing the increase in device complexity by consolidating multiple monitoring needs into a single system.
