Background: We planned to investigate the effect of preoperative short period intensive physical therapy on lung functions, gas-exchange, and capacity of diffusion, and ventilation-perfusion distribution of patients with non-small cell lung cancer. Methods: Sixty patients with lung cancer, who were deemed operable, were randomly allocated into two groups. Intensive physical therapy was performed in patients in the study group before operation. Both groups received routine physical therapy after operation. Results: There was no difference in pulmonary function tests between the two groups. Intensive physical therapy statistically significantly increased peripheral blood oxygen saturation. At least one complication was noted in 5 patients (16.7%) in the control group, and 2 (6.7%), in the study group. However, there was no statistically significant difference (p = 0,4). The hospital stay has been found to be statistically significantly shortened by intensive physical therapy (p <0.001). Ventilation-perfusion distribution was found to be significantly effected by intensive physical therapy. The change was prominent in the the contralateral lung (p <0.001). Conclusions: Intensive physical therapy appeared to increase oxygen saturation, reduce hospital stay, and change the ventilation/perfusion distribution. It had a significant, positive effect on the exercise capacity of patients.

AIMS: We aimed to investigate the effectiveness of a telerehabilitation exercise program performed without requiring any special equipment on the physical condition of COVID-19 subjects. SETTINGS AND DESIGN: This was a randomized controlled study. METHODS: This study included subjects with a history of hospitalization with a diagnosis of COVID-19 and discharged within 4 weeks. The subjects were divided into two groups randomly, namely telerehabilitation group (TeleGr, n = 17) or control group (CGr, n = 17). The TeleGr received breathing and range of motion exercises, active cycle of breathing technique, and an aerobic training 3 days a week for 6 weeks, while CGr received an exercise brochure with the same content. Subjects were evaluated using the modified Medical Research Council (mMRC) dyspnea score for dyspnea, 30 s sit-to-stand test (30STS) and short physical performance battery (SPPB) to determine their physical status, Saint George Respiratory Questionnaire (SGRQ) to assess quality of their life, and Beck Depression Inventory. All evaluations were carried out at home using videoconferencing. RESULTS: A significant improvement was observed in TelerGr in terms of mMRC (P= 0.035), 30STS (P= 0.005), 5 sit-to-stand time which is one of the subtests of SPPB ( P = 0.039) and SGRQ scores. Significant improvement was observed only in the pain score in the CGr ( P = 0.039). There was a statistically significant difference between the groups in SGRQ activity ( P = 0.035) and total ( P = 0.042) scores. In addition, more symptomatic improvement was found in TeleGr. CONCLUSION: Telerehabilitation exercise program with less technical equipment is a good alternative treatment method for COVID-19 subjects, which improves the quality of life and symptomatic status of subjects.

A greater increase in exercise capacity was observed in the PR + IMT group. Our study showed that inspiratory muscle training improved exercise capacity even further and increased the benefits provided by pulmonary rehabilitation.
