Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Prospective cohort
Participants will be shown a paced breathing programme and instructed to implement this for 10 minutes twice daily for 4 weeks.
During the 10-minute breathing exercises, the participant will need to wear the Polar H10 chest strap and can remove this when finished.
The breathing will ideally be a breathing pattern of a 4-second nasal inhale, and 6-second nasal exhale using the 'resonance' programme in the 'biofeedback' section of EliteHRV app.
They will be advised to monitor the graph of HRV on EliteHRV which allows real-time assessment of HRV and to aim to breathe in and out deeply to raise the HRV graph reading as much as possible each time.
They will be advised to perform the breathing programme lying down with minimal distractions on waking in the morning and just before bed in the evening, preferably in the same location each time.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Modified C19-YRS (COVID-19 Yorkshire Rehabilitation Scale)
Time Frame: Up to 6 weeks
|
The C19-YRSm will be completed by the patient every week for a total of 6 weeks.
There will be a total of 7 C19-YRSm documents completed.
The C19-YRSm consists of 17 items with each item rated on a 4-point numerical rating scale from 0 (no symptom) to 3 (life disturbing or affecting all aspects of daily life).
The C19-YRSm is divided into four subscales (range of total score for each subscale): symptom severity score (0-30), functional disability score (0-15), other symptoms (0-25), and overall health (0-10).
A higher score for the first 3 subscores represents higher severity.
Conversely, a lower overall health score represents greater severity.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
HRV (Heart Rate Variability) score
Time Frame: Up to 6 weeks
|
We will be collecting both medium and short term HRV data. Participants will wear a Fitbit for 6 weeks which will collect HRV data whilst sleeping each night, thus collecting 6 weeks of consecutive nocturnal HRV data. In addition they will wear a Polar H10 chest strap for 10 minutes twice daily whilst performing breathing exercises to collect frequent short-term HRV data. For both data sets an increase in HRV is expected as this denotes an improvement in heart rate variability. Fitbit measures HRV in milliseconds on a scale from 0 to 100 (or more if HRV exceeds 100ms) A higher score represents more variability and therefore improvement. The Elite HRV also provides a score of HRV on a scale from 0 to 100 with a higher score representing improvement. The score is derived from the root mean square of successive differences between heartbeats in milliseconds (rMSSD). |

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
COMPASS 31(Composite Autonomic Symptom Score)
Time Frame: Up to 6 weeks
|
The COMPASS 31 will be completed by the participant at the initial visit and again 6 weeks later at the end of the study.
Autonomic symptoms are scored for different domains including orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder and pupillomotor.
Total scores for each domain are multiplied by a set weighting and then added together to provide a score out of 100 representing severity of autonomic symptoms.
A higher score represents greater severity
|
Up to 6 weeks
|
EQ5D-5L(EuroQol Five Dimension Quality of Life)
Time Frame: Up to 6 weeks
|
The EQ5D-5L will be completed by the participant at the initial visit and again 6 weeks later at the end of the study.
4 domains are assessed on a scale of 1 to 5: mobility, self-care, usual activities, pain/discomfort and anxiety and depression.
A greater score represents greater severity.
In addition participants self-rate their overall health on a scale f 0 to 100. 100 represents best health possible and 0 represents worst health possible.
|
Up to 6 weeks
|
aAP(Adapted Autonomic Profile)
Time Frame: Up to 6 weeks
|
Participant will complete an aAP at initial visit and again 6 weeks later at the end of the study.
This test has binary outcome: normal or abnormal.
There is no score generated by the test.
We will assess whether those deemed normal or abnormal at the beginning change as a result of the intervention.
|
Up to 6 weeks
|
World Health Organisation Disability Assessment Schedule (WHODAS)
Time Frame: Up to 6 weeks
|
This is validated generic measure of functioning and disability.
The 36-item scale captures six domains of life (cognition, mobility, self-care, getting along, life activities and participation) with a summary score ranging from 0 (no disability) to 100 (full disability)
|
Up to 6 weeks
