RMT Monitor

Value Proposition

Respiratory muscle training (RMT) improves the function of respiratory muscles by delivering a flow-resistance or pressure-threshold stimulus to those muscles to increase their strength, endurance and/or performance. Accumulating clinical research data suggests RMT has therapeutic benefit in patients that are suffering from respiratory muscle dysfunction, including patients with dysphagia, Parkinson, stroke, COPD, asthma, spinal cord injury, ALS, and Pompe disease. Clinical evidence also suggests RMT can improve the respiratory function in high-performance individuals, such as athletes and professional voice users. However, current RMT devices have a functional limitation: RMT devices do not provide training monitoring, have unaccepted level of error when providing intended resistance, and lack performance feedback to the users.


The inventors created a monitor that can be attached on most commercially available RMT devices. This invention can automatically collect adherence and performance data. As a result, laborious and prone-to-error written training logs are no longer needed since data recorded on this device can be downloaded through USB, wireless or Bluetooth. In addition, RMT devices have high level of error when providing intended resistance. Dr. Jones’ invention allows users to program RMT device precisely to intended resistance though an internal pressure transducer. To ensure training accuracy, Dr. Jones’ invention provides a shut-off feature to safeguard not only correct pause interval between training repetitions but also prevent adverse effect from overtraining. Moreover, existing RMT devices do not provide users with feedback regarding individual RMT repetitions. This is challenging to users because they need to be trained extensively to recognize whether RMT repetitions are successful. This monitor provides real-time visual and auditory feedback to trainers so they can adjust their performance accordingly during training.
