Correlation between 1-min-sit-to-stand test and 6-min-walk-test for evaluation of cardio-respiratory parameters in patients with Interstitial Lung Disease

Patients would be chosen from PGIMS, Rohtak’s Department of PCCM. There will be 80 patients enrolled in this trial. Participants will be randomly assigned to one of the intervention groups (Group-A/Group-B) with a 30-minute washout period using a computer-generated randomization list. All participants will take part in both therapies. All demographic information will be collected, and participants will be assessed for baseline readings (before intervention) of the cardio-respiratory parameters listed below, with values labeled "PRE-A1/ PRE-B1" based on the group in which the patient would be enrolled: - Heart rate (HR), Blood Pressure (BP), Dyspnea and SpO2 levels. Intervention A/Group A will take PRE-A1 assessments. Participants will do 6MWT. Immediately following the test, post-intervention measurements of the outcome measures listed below will be made and labeled as POST-A1 - HR, BP, SpO2 and Dyspnea. The subject will have a 15-minute break. PRE-A2 actions are planned. Participants will complete 6MWT twice. Immediately following the test, post-intervention measurements of the outcome measures listed below will be made and labeled as POST-A2 - HR, BP, SpO2, Dyspnea. The washout interval is 30 minutes. Group B/Intervention B: PRE B2 actions will be implemented. Participants will execute 1STST. The following outcome measurements will be measured after the test and labeled as POST-B1: - HR, BP, SpO2 and Dyspnea. The subject will be given 30 minutes of rest. Pre-B2 measures will be implemented. The subjects will repeat 1STST twice. Following the test, a post-intervention measurement of the outcome measures listed below will be conducted and recorded as POST-B2 - HR, BP, SpO2 and Dyspnea.
