Exercise interventions included two sections- breathing exercises and corrective exercises in the cervical and thoracic spine. The spirometry test, craniovertebral angle, and thoracic kyphosis test were used. To evaluate differences between variables, paired-samples t-test and ANCOVA were used (<jats:italic>p<\/jats:italic>-value\u2009&lt;\u20090.01). Also, Eta-squared was measured to assess the effect size.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Results showed a significant difference between the two groups in craniovertebral angle (<jats:italic>P<\/jats:italic>\u2009=\u20090.001), thoracic kyphosis (<jats:italic>P<\/jats:italic>\u2009=\u20090.007), and respiratory capacity including Forced expiratory volume in one second (FEV1) (<jats:italic>P<\/jats:italic>\u2009=\u20090.002), FEV1\/FVC (<jats:italic>P<\/jats:italic>\u2009=\u20090.003), Peripheral oxygen saturation (SPO2) (<jats:italic>P<\/jats:italic>\u2009=\u20090.001), while no significant differences were observed between two groups in terms of chest anthropometric indices (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.01). The Eta-squared value of 0.51 for the Craniovertebral angle and the SPO2 indicates a large effect size.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The results showed the combination of corrective and breathing exercises could improve pulmonary function and correct cervical and thoracic posture in patients with a history of COVID-19 infection.
