Force and Movement Sensing Belt for Rehabilitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current musculoskeletal rehabilitation methods lack effective tools for patients to perform exercises correctly without supervision, leading to low adherence and ineffective rehabilitation due to the inability to measure and ensure proper force and movement execution.
Innovation Solution
A device and system that simultaneously measures force and movement during rehabilitation exercises, wirelessly transmitting data for analysis, and a method that includes a database for personalized feedback and real-time correction, using a belt with sensing modules and a processor to compare actual performance with prescribed parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rehabilitation exercises are performed without supervision, then patient autonomy and convenience are improved, but exercise execution accuracy and rehabilitation effectiveness deteriorate
Solution Approach 1:
The system implements real-time feedback by measuring force and movement parameters during exercise execution, comparing them against prescribed parameters, and providing immediate notifications when deviations occur. This allows patients to perform exercises autonomously while maintaining accuracy through continuous monitoring and feedback.
Solution Approach 2:
The patent replaces manual supervision by physiotherapists with an automated electronic monitoring system that uses force sensors and movement sensors to objectively measure exercise parameters and provide feedback, eliminating the need for constant human oversight.
2Device complexity
If standardized movement parameters are used for all patients, then system simplicity and ease of implementation are improved, but patient-specific rehabilitation effectiveness and injury prevention deteriorate
Solution Approach 1:
The system enables personalized rehabilitation by allowing different force and movement parameters to be prescribed for each patient based on their specific condition, injury type, and rehabilitation stage. Each patient receives customized exercise parameters rather than standardized ones, improving rehabilitation effectiveness.
Solution Approach 2:
The system allows rehabilitation parameters to be dynamically adjusted for each patient based on their progress and specific needs. The prescribed force and movement parameters can be modified over time as the patient improves, making the rehabilitation process adaptive rather than static.
3Measurement precision
If force measurement capabilities are added to rehabilitation systems, then exercise intensity monitoring is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines force measurement capabilities with movement measurement capabilities in a single integrated system. The force sensor and movement sensor work together to provide comprehensive exercise monitoring, reducing overall system complexity compared to separate systems.
Solution Approach 2:
The monitoring system is designed to measure multiple parameters (force, movement, position) using a unified platform that can handle various rehabilitation exercises. This multi-functional approach reduces complexity by avoiding the need for separate specialized equipment for each measurement type.

AI summary
The device comprises a belt (3) on which is mounted a first sensing module (4), with: a) a hitch (6) for connecting a recovery component part (7) such as a spring; b) a first movement sensing unit (8) to detect 3D movement; c) a force sensing unit (9) to detect the force exerted by the recovery component part (7) upon the hitch (6); in which the movement and force data are processed and sent wirelessly via a data transmission unit (11); and d) first means of closure (13,14), to close the belt (3) to a required dimension. Allows simultaneous and coordinated consideration of force and movement data.
