Study summary

The aim of the study is to test a treatment known as "Cognitive Muscular Therapy (CMT)" for reducing breathlessness and improving autonomic function in patients with long-COVID.

Read the detailed description

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

Inclusion criteria

  • Above 18 years old
  • Experience moderate/severe breathlessness, quantified using the Modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm) scale.
  • Speak and understand English sufficiently to read the information sheet and sign the consent form
  • Ability to stand without any assistive device for at least 20 minutes (to ensure sufficient capacity to complete the intervention)

Exclusion criteria

Exclusion Criteria:

  • Dementia or other major cognitive impairment
  • >32 (as increased subcutaneous fat prevents use of breathing measurement system)
  • Current smoker or smoked regularly within last 6 months
  • Any cardiorespiratory disease that requires medical intervention (except asthma management)
  • Currently receiving physiotherapy-based treatment for LC or breathing pattern disorder
  • Significant respiratory co-morbidity (e.g. , uncontrolled Asthma)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Study arms

  • Experimental
    Treatment

    Each participant will receive seven weekly sessions of Cognitive Muscular Therapy (CMT) + Breathing Visualisation at the University of Salford from an respiratory physiotherapist. This physiotherapist will have been trained to deliver the CMT intervention and will have at least three years' experience of working with patients with respiratory disorders. Each treatment session will last 45-60 mins. The CMT intervention comprises five components: Understanding long-COVID, general relaxation, postural deconstruction, contextual triggers and functional integration. Breathing Visualisation will be integrated into session 5, 6 and 7.

    Behavioral: Cognitive Muscular Therapy · Behavioral: Breathing visualisation

Interventions

  • BehavioralCognitive Muscular Therapy

    Psychologically informed physiotherapy which integrates training to reduce overactivity of postural muscles which can interfere with the mechanics of breathing.

  • BehavioralBreathing visualisation

    Breathing visualisation; Data from two 3D camera are combined and used to calculate respiratory volumes. These volumes are then used to drive an animation of breathing so that the patient can understand how their breathing pattern compares to an optimal pattern. Note this is not a medical device as data from this system is only used for education and not for diagnostic or treatment decisions.

What researchers measure

Primary outcomes

  1. Change in Nijmegen Questionnaire

    Used to capture breathlessness symptoms associated with hyperventilation disorder. Score 0 - 60 (0 = no hyperventilation symptoms, 60 severe symptoms of hyperventilation).

    Time frame: Change from Baseline to two months (post intervention) & change from Baseline to 5 months (post intervention)

Secondary outcomes

    Used to capture breathlessness symptoms associated with long-COVID compared to pre-acute infection. Score 0 - 45 (0 = no long-COVID symptoms, 45 severe symptoms of long-COVID).

    Time frame: Change from Baseline to two months (post intervention) & change from Baseline to 5 months (post intervention)

  2. Change in Dyspnea-12 questionnaire

    Used to capture breathlessness symptoms. Score 0 - 36 (0 = no breathlessness symptoms, 36 severe breathlessness).

    Time frame: Change from Baseline to two months (post intervention) & change from Baseline to 5 months (post intervention)

  3. Change in Self-evaluation of breathing questionnaire

    Used to capture breathlessness symptoms associated with dysfunctional breathing. Score 0 - 75 (0 = no dysfunctional breathing symptoms, 60 severe symptoms of dysfunctional breathing).

    Time frame: Change from Baseline to two months (post intervention) & change from Baseline to 5 months (post intervention)

  4. Change in Composite Autonomic Symptom Score

    Used to capture symptoms associated with autonomic dysfunction. 31 questions rating the symptoms associated with autonomic dysfunction.
