Human Corona Viruses (HCoV) are of the Nidovirales order and are characterized by positive single-sense RNA. Seven strains have been discovered since 1965. At end of 2019, a new strain was detected, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV2). The main structure of this virus comprises a genome covered by several layers of proteins. This structure allows the virus to target the human body through the Angiotensin-Converting Enzyme 2 (ACE2), disrupting alveoli cells reducing the O2 rate, leading to lung fibrosis negatively affecting respiratory Vital Capacity (VC). Thus, chest physiotherapy is aproposed therapeutic modality that offers a variety of techniques that greatly benefit the respiratory system. Similarly, nutrition plays an important role in improving the immune system’s function, and so is also strongly related to severity and mortality rates in cases of SARS-CoV2. Aim of the study: This study examines whether a chest physiotherapy program intervention on children post SARS-CoV2 will enhance vital lung capacity. Methods: The study participants are (34) children post-SARS-CoV2, ranging in age range from 6 to 14 years. The control group comprises 17 children (who are not receiving any intervention), and the experimental group comprises 17 children (who receive aspecific chest physiotherapy program intervention).Randomization between both groups was performed using block randomization, and Spirometry and Chest Expansion Measurement (CEM) are both used as outcome measures. The specific chest physiotherapy program intervention includes (posture drainage, active cycle breath exercise, percussion, passive stretch, myofascial release, diaphragm breath exercise, and home nutrition instructions). Results: Fifty-eight percent of patients were males (58.8%) with a mean age of 11.18 years (SD=2.42 years) and a mean height of (133.74 cm) and weight of (32.41 Kg), and a mean BMI of 18.04 Kg/m2. There were no significant differences between the control and experimental groups with regard to any of the children's characteristics. The mean baseline of FVC was not significant, as the mean FVC in the total control sample was 2.4 L, while FVC in the experimental group was 2.42 L, P=0.910. A measurement of FVC is a significant group by time interaction p<0.001. The group who received the chest physiotherapy program intervention performed better than the control group in spirometry p<0.001. A comparison between post-intervention and pre-intervention revealed the experimental group attained significant improvement in FVC measured by spirometry at p<0.001, with a mean difference = 0.865L. There was no significant change from baseline in the CEM at baseline p=0.232. The group-by-time interaction for CEM was statistically significant p=0.002. The experimental group performed no better than the control group in terms of CEM p=0.131. However, the group who received the intervention showed significant improvements in the expansion of the chest post-intervention compared to the pre-intervention p= 0.05, with a mean difference = 0.765CM. Meanwhile the control group showed no change in chest expansion at the upper level of CEM after the intervention (p=0.269).
