Abstract
Background Management of Long COVID (LC) is hugely challenging for clinicians. This pilot study evaluated a breathing retraining and singing programme (SingStrong for LC) to address common LC symptoms. The study hypothesized that this intervention would improve symptoms impacting disordered breathing and participant wellbeing. Methods The 10-week, bi-weekly online programme was comprised of a 45-min class of mindfulness, breathing retraining, vocal exercises, and singing. Sessions were recorded for non-attenders and conducted by a trained vocal coach experienced in respiratory cohorts. Persons with a confirmed COVID-19 diagnosis and persisting symptoms were invited to participate. Demographic and COVID-19 data were collected, and the DePaul Symptom Questionnaire Short Form (DSQ- SF) and COVID-19 Yorkshire Rehab Screen questionnaires were administered. Post-intervention focus groups were also conducted. Results Of 27 (F = 23(85%)) participants recruited, data from 21 who completed at least 10 (50%) classes were analysed. Participants showed significant pre--post-intervention improvements in all breathlessness symptoms (at rest: P \< 0.001; dressing: P = 0.01; stairs: P \< 0.001), fatigue (P = 0.03), usual activities (P = 0.04), pain/disability (P = 0.03), voice quality (P = 0.01), and communication/cognition (P = 0.04). Pre--post number of instances meeting DSQ-SF criteria for myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) decreased by a net of nine cases (14.3%). No association between COVID-19 hospitalisation status and diagnosis of ME/CFS was identified. Qualitative feedback from eight participants was overwhelmingly positive with all reporting improvements in breathing and general well-being. Conclusion The SingStrong programme shows promise as a viable treatment option for LC sufferers. Future studies are required to further investigate the efficacy of this intervention.
