Cognitive Muscular Therapy for Patients With Long-COVID and Breathing Pattern Disorder

A key symptom of long-COVID is dysfunctional breathing, characterised by an alteration in the muscular and mechanical control of breathing, such as altered movement/coordination of diaphragm and ribs. Long-COVID patients also experience symptoms such as dizziness and fatigue, which have been linked to dysautonomia (dysfunction of the nervous system controlling automatic body functions). Importantly, dysautonomia is connected to alterations in breathing mechanics. Specifically, rapid breathing, high in the chest, is associated with increased activity in the fight-or-flight system and decreased activity in the rest-and-repair system. Given this link, interventions capable of improving breathing mechanics could alleviate many long-COVID symptoms. However, current breathing retraining methods lack visualisation of breathing mechanics and do not integrate a whole-body approach to improving postural control. We have developed a clinical system which can visualise breathing mechanics in real-time, providing patients with a "window into their body". We propose to integrate this system within a new intervention, known as Cognitive Muscular Therapy (CMT). CMT integrates psychological informed physiotherapy with training to reduce overactivation of postural muscles which can interfere with the mechanics of breathing. We propose to test this combined intervention on 20 people with Long-COVD to understand if we can improve respiratory function and symptoms associated with dysautonomia. If successful, this pilot study could pave the way for large-scale studies in long-COVID
