The one session of deep tissue massage was performed. The patient's positions were changed depending on the specificity of used techniques.

The following techniques were used:

• Shifting the rectus abdominis m.,
• Stretching of the fascia within the costal arches,
• trigger points compression (30-60 s).
• Stretching of the chest fascia, superficially with forearm or fingertips on intercostal muscles,
• "filleting" the pectoral muscles,
• "hook and stretch" with the proximal phalanges of the fingers 2-4 and the forearm
• "filleting" between the pectoral muscles and the deltoids,
• Releasing the lateral edge of the scapula using the fingers and stretching the tissues, Releasing the medial edge of the scapula using the fingers and the weight of the patient,
• "hook and stretch" of the trapezius muscle,
• Subsequently, the patient took a prone position.
• Stretching of the levator scapulae and supraspinatus muscles using the fist, forearm and elbow were performed.

The one session of classic massage was performed. The massage was performed with moderate force. The entire procedure took about 15-20 min. The sequence of standard classic massage techniques was used in standard way and patterns.

Administered as a soft tissue mobilization performed by the therapist with fingertips, knuckles, elbows and/or fists on the tissues that manifest symptoms of fascial restrictions. The techniques were performed with individually adjusted force until the change (eg. increased mobility) in the tissue being treated was stated by the therapist.

The vital capacity of the lungs was assessed with spirotest (Riester, mod. 5260). The subject stood with legs hip-width apart. For each measurement, disposable cardboard mouthpieces were used. The examined person held the device vertically with both hands. At the examiner's command, subject took in as much air as possible, then tightly bit the mouthpiece with his mouth, and with all of their strength, exhaled air into the device for as long as possible. The subject had only 1 attempt-measured values were recorded with an accuracy of 50 mL.

Testing blood oxygen saturation was performed in a sitting position with digital pulseoximeter CMS50D. The device was put on the second finger of the left hand each time. The highest value displayed by the pulseoximeter within 30 s was recorded with an accuracy of 1%.

The chest circumference was measured with a measuring tape, wrapped horizontally around the chest at the level of the xiphoid process. The subject was standing with feet hip-width apart, arms hanging along the body. At the command, the subject would take a maximum breathe in (first measurement) and exhale to the maximum for the next (second measurement). Obtained values were recorded with an accuracy of 0.5 cm.

Dynamic spirometry test was performed, assessing the peak expiratory flow (PEF) measured in liters per second [l/s]. The test was performed with PNEUMO® spirometer and PNEUMO 2005 software (abcMED). The subject was sitting with his legs on the floor-hip joint flexed at an angle of 70o-90o and carried out the following command: "Breathe calmly. On my command, breathe in as much as possible, as quickly as possible, as intensively as possible, and while at the top of the inhalation, without waiting, breathe out as hard and as long as possible ". This cycle was performed at least 3 times obtaining 3 measurements according to the standard ERSATS 2005.
