The aim of this work was to evaluate the effectiveness of physiotherapy interventions after cesarean section using standardized questionnaires, objective measurements and subjective assessments of pain intensity in the patient before and after the physiotherapy intervention on the presented case of an older primiparous woman (primipara vetusta). By assessing the posture of the mother in the sagittal, frontal plane from the front and back, the posture improved, achieving physiological curves of the spine and reducing muscle tension by equalizing tone. By measuring the muscle strength with a manual muscle test, there was an increase in the muscle strength of the rectus abdominis and obliques abdominis from -4 to 5, which was achieved by the described kinesitherapy. Manual measurement of the width and depth of the diastasis showed its reduction. The described closure of the diastasis was achieved by a combination of abdominal breathing and exercises, myofascial relaxation of the abdomen and pelvis, and education about activities that should be avoided when the diastasis exists. The intensity of pain assessed with a visual-analog scale showed the complete disappearance of unbearable pain with an intensity of 10/10. By assessing the condition of the scar using the Vancouver scale, there was a reduction in inflammatory pigmentation and an improvement in the mobility of the scar, which is also shown by the scoring of the scale (from the initial 5 out of 13 to 2 out of 13).
