Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Comprehensive pre- and post-intervention assessments will be conducted, including exercise capacity, respiratory and peripheral muscle strength, trunk endurance, balance, anxiety, depression, and fatigue levels. The primary outcome measures are respiratory muscle strength and trunk endurance.
Participants must be aged 18-65 years, have at least a primary education level, speak Turkish, and be classified as level 2-3 on the Post-COVID-19 Functional Status Scale (PCFS). Eligible participants will be referred by the Internal Medicine Department at Hacettepe University.
The study will utilize various assessment tools, including maximal inspiratory/expiratory pressure (MIP/MEP) tests, Functional Movement Screen (FMS), plank and Sorenson endurance tests, the Timed Up and Go Test for balance, handgrip and knee extension strength tests, body composition analysis, and the SF-36 quality of life questionnaire.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants to be included in the study will consist of individuals diagnosed with post-COVID syndrome and will be divided into two groups with a computer-aided stratified randomization method.
After the patients are randomly separated, one group will receive 8 weeks of core stabilization training and the other group will receive functional IMT (IMT combined with core stabilization) training. The exercise program is designed to last 8 weeks in total, and the training program for both groups will be carried out on certain days (3 days) per week, and each session will last 50 minutes.
A comprehensive assessment will be applied to both groups at the beginning and end of the study. These assessments are; exercise capacity, respiratory muscle strength, peripheral muscle strength, trunk muscle endurance, balance, anxiety and depression levels, and fatigue level parameters. The primary outcome measure of the study will be respiratory muscle strength and trunk muscle endurance.
Individuals who meet the inclusion criteria will be included in the study. The study will be conducted with individuals between the ages of 18-65, with at least primary school education, and whose local language is Turkish. Participants diagnosed with Post-COVID-19 Syndrome and who are in class 2-3 according to the Post-COVID-19 Functional Status Scale (PCFS) will be included in the study. Participants who are eligible for the study will be directed to the Cardiopulmonary Rehabilitation Unit of the Hacettepe University Faculty of Physical Therapy and Rehabilitation by the relevant physicians of the Department of General Internal Medicine of the Hacettepe University Department of Internal Medicine.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Core Stabilization Group
Participants will receive an 12-week core stabilization exercise program only.
Core Stabilization
12-week supervised core stabilization training, 3 sessions per week, 45 minutes per session.
Functional IMT Group
Participants will receive an 12-weeks core stabilization exercise program plus functional inspiratory muscle training (IMT).
Core Stabilization
12-week supervised core stabilization training, 3 sessions per week, 45 minutes per session.
Functional Inspiratory Muscle Training (IMT)
IMT using a portable inspiratory muscle training device at 60% MIP, progressively increased over 12 weeks.
