Thoracic ROM measurement system with visual bio-feedback: system design and biofeedback evaluation.

Area of Science:

• Biomedical Engineering
• Respiratory Physiology
• Rehabilitation Technology

Background:

• Chronic obstructive pulmonary disease (COPD) and other conditions impair thorax mobility, impacting respiratory function.
• Thoracic range of motion (ROM) is a key indicator of respiratory health.
• Existing methods for measuring thoracic ROM may lack real-time feedback for patient guidance.

Purpose of the Study:

• To develop and validate a prototype system for measuring thoracic ROM with real-time visual biofeedback.
• To assess the repeatability and reliability of the developed thoracic ROM measurement system.
• To investigate the impact of real-time visual biofeedback on respiratory function during chest expansion tests.

Main Methods:

• A novel system utilizing a wire-type linear encoder wrapped around the thorax was developed to measure thoracic ROM.
• The system incorporates real-time visual biofeedback to guide patients during breathing exercises.
• Repeatability, reliability, and the effect of biofeedback on respiratory function were evaluated through experimental testing.

Main Results:

• The developed thoracic ROM measurement system demonstrated good repeatability and reliability in initial assessments.
• Real-time visual biofeedback facilitated easier maintenance of larger and more stable thoracic ROM during deep breathing exercises.
• The system shows promise for enhancing respiratory rehabilitation and patient monitoring.

Conclusions:

• The prototype thoracic ROM measurement system with real-time visual biofeedback is a reliable tool for assessing respiratory function.
• Visual biofeedback significantly improves the ability to achieve and sustain optimal thoracic ROM, beneficial for patients with respiratory conditions.
• This technology offers a simple yet effective method for improving thorax mobility and respiratory control.
