The patients will participate in a 14-day rehabilitation program (Monday to Saturday). Treatments and therapies will be continued for a maximum of two hours daily. The program will be applied individually to each patient and include active and assisted exercises, effective cough exercises, pursed-lips breathing, positive expiratory pressure exercises, exercises to strengthen the diaphragm and intercostal muscles and cardiopulmonary exercises.

Measurements will be performed with pulse oximeter and the parameter analyzed will be the number of patients' heart beats per minute.

The test will be performed in 20-meter long hospital corridor. The patient should walk the distance at his own rhythm and pace, using orthopedic aids (if necessary). The patient will be informed that they can stop the test at any time if they feel it is necessary. The distance traveled in meters in 6 minutes will be analyzed.

The test comprising muscle endurance, aerobic capacity, flexibility, agility, and balance assessment. The test consist of 6 activities: 1. Arm Curl Test (number of forearm flexions in 30 seconds); 2. Back Scratch (the distance between middle fingers); 3. 30 Second Chair Stand (number of standings in 30 seconds); 4. Chair Sit-and-Reach ( '+' if fingers can reach toes in sitting position, '-' if fingers cannot reach toes in sitting position); 5. 8 - Foot Up-and-Go (8-foot walking time); 6. 2-Minute Step-in-Place (the number of lifts of the right leg).

Fatigue will be examined during physical activity and the level of fatigue will be marked on a scale from 1 (no fatigue) to 10 (very very hard fatigue).

Assessment of quality of life, health and other areas. The scale contains 26 items, divided into four domains: physical health (7 items), psychological health (6 items), social relations (3 items), and environmental health (8 items), as well overall quality of life and general health (2 items). Patients express how much they have experienced the items in the preceding 2 weeks on a 5-point Likert scale ranging from 1 (not at all) to 5 (completely). The final score is transformed linearly to a 0-100-scale, where higher scores denote higher quality of life.

The scale consists of 16 statements to which the respondent refers on a four-point scale. Eight statements are used to measure anxiety and depression, each of which is rated on a scale of 0 to 3 points. The cut-off threshold is 7 points for depression and 7 points for anxiety. The intensity of depressed mood and anxiety will be analyzed.

Life independence test, i.e. ensuring the functioning of the household by a sick person based on his/her ability to cope in the external environment or with a complex activity such as using the telephone and ensuring the related opportunities. The ability of basic functioning in the environment will be analyzed and each of 8 items will be rate trichotomously (1 = unable, 2 = needs assistance, 3 = independent) and sum the eight responses. The final total score ranges from 8 (low functioning, dependent) to 24 (high function, independent).
