ABSTRACT
Introduction: It is known that around one third of Coronavirus Disease-2019 (COVID-19) patients develop severe pulmonary complications and acute respiratory distress syndrome, leading to long-term impairments in Pulmonary Function Test (PFT) and physical performance. Due to deteriorating health status of the COVID-19 survivors after their recovery, rehabilitation is must. Aim: To evaluate the effect of soft tissue manual technique and breathing exercises on PFT, chest expansion and functional status in Post COVID-19 Survivors. Materials and Methods: This quasi-experimental study was carried out in the Department of Cardiorespiratory Physiotherapy, MGM hospital, Aurangabad, Maharashtra, India, from November 2021 to July 2022. Total 54 subjects diagnosed with COVID-19 who required oxygen therapy and had persistent respiratory symptoms for three weeks to six months after the infection, were included. All the subjects received one week of soft tissue manual techniques which included proprioceptive neuromuscular function, muscle energy technique for recruitment of diaphragm, muscles of respiration and the ribcage. Breathing exercises were inculcated at the end of the session to ensure relaxation of the subjects. Subjects were assessed for PFT, chest expansion and post COVID-19 Functional Status Scale (PCFS) pre and post-treatment. Data were analysed through Wilcoxon signed-rank Test. Results: Amongst total 54 subjects included, 10 (18.6%) males and 44 (81.4%) females with mean age of 29.92±11.94. After one week of intervention p-value was 0.0001 for Forced Expiratory Volume (FEV1), FEV1/Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF) with mean values for FEV1 at baseline was 1.91±0.51 and post-treatment was 2.45±0.34, FVC was 2.25±0.50 before the treatment whereas it was 2.73±0.36 post-treatment with p-value of 0.002, FEV1/FVC and PEF was 83.99±12.03 and 4.36±1.78 at baseline whereas, post-treatment it was 87.76±7.29 and 5.88±0.95 respectively. The p-value of 0.0001 was also similar for chest expansion. No statistically significant difference was found in post COVID-19 functional status (p-value=0.013). Conclusion: Positive changes in the ribcage's activation and integration with its muscles were seen in all of the study variables. Therefore, it is concluded that soft tissue manipulation techniques and breathing exercise improves functional status, thoracic expansion, in post COVID-19 survivors.
