Visual Feedback Physical Therapy Device for Limb Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients undergoing physical therapy for lower extremity injuries face challenges in maintaining proper biomechanics without continuous guidance from a trained physical therapist, leading to potential setbacks and increased risk of injury during home-based therapy.
Innovation Solution
A visually guided physical therapy device equipped with a light emitter and tracking pattern provides visual feedback to patients, allowing them to perform exercises with proper motion and receive real-time feedback on faulty biomechanics, enabling self-guided therapy at home.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients perform physical therapy at home without continuous therapist guidance, then therapy convenience and accessibility are improved, but the risk of faulty biomechanics and injury increases
Solution Approach 1:
The patent employs visual feedback through a light emitter that projects a light dot onto a tracking pattern on the floor. The position of the light dot relative to the tracking pattern provides real-time feedback to the patient about their limb position and movement accuracy, enabling them to self-correct biomechanical faults during home therapy exercises.
Solution Approach 2:
The patent introduces an intermediary visual guidance system consisting of the light emitter and tracking pattern. This intermediary mediates between the patient's movements and the desired biomechanical form, translating complex therapeutic requirements into simple visual cues that patients can follow without therapist intervention.
2Measurement precision
If continuous therapist supervision is provided to ensure proper biomechanics, then movement accuracy is improved, but therapy cost and time commitment increase
Solution Approach 1:
The patent enables patients to perform self-service physical therapy with accurate movement guidance through the visual feedback system. The light emitter and tracking pattern allow patients to independently monitor and correct their own biomechanics, eliminating the need for continuous therapist supervision and reducing time commitment while maintaining movement accuracy.
3Reliability
If visual feedback systems are implemented to guide patient movement, then biomechanical control is improved, but device complexity increases
Solution Approach 1:
The patent segments the visual feedback system into simple, independent components: a light emitter attached to the patient's limb and a static tracking pattern on the floor. This segmentation allows the system to provide effective visual feedback without requiring complex integrated systems, maintaining simplicity while improving neuromuscular control.

Data Source
AI summary
A physical therapy device is disclosed. An example of the physical therapy device includes a cuff for attachment to a patient's limb. The example physical therapy device also includes a light emitter mounted to the cuff. The example physical therapy device also includes a tracking pattern corresponding to at least one physical therapy exercise. The patient performs the physical therapy exercise by moving the patient's limb in such a manner so as to track light from the light emitter on the tracking pattern.
