Visual Analogue Scale (VAS) will be used to evaluate the severity of low back pain. The back pain they feel during activity and rest will be questioned separately from the participants. For this assessment, patients will be asked to mark their pain intensity on a 10-centimeter line. Pain intensity will be determined by measuring the distance of the marked point to the "0" point with a tape measure. Scoring is made between 0-10 and "0 means no pain"- "10 means the most severe pain imaginable".

The six-question form allows evaluation of the frequency of urinary incontinence and during which activities it occurs. The validity and reliability study of the Turkish version of the test was done by Çetinel et al. made by Scoring is done with frequency, amount and degree of impact questions, a total score between 0-21 is obtained. A low score indicates that urinary incontinence affects the quality of life less, and a high score indicates that the involvement is high. For the ICIQ-SF, a score of 8 and above was determined as the most appropriate cut-off value for irritating urine leakage.

The physical activity level of the participants will be evaluated with the International Physical Activity Questionnaire (IPAQ). The survey consists of a total of 5 sections and 27 questions. Information is obtained about the light, moderate and vigorous activities that the person has done in the last week and the sitting time. For physical activities performed for at least 10 minutes, the MET value (metabolic equivalent) is multiplied by the number of days and minutes to obtain the MET-min/week score. Classification according to the energy level spent in METs is made as no physical activity (MET=<600), insufficient activity (MET=600-3000), and adequate activity level (MET= >3000).

The muscle strength of the participants will be determined by the Manual Muscle Test. The person is asked to move against gravity by taking the appropriate position for the muscle to be evaluated. If the movement can be done up to the desired part (3) it is scored as medium, if it receives minimal resistance (3+) if it gets a little good from the middle, if it can get moderate resistance (4) good, if it can get full resistance (5) it is normal. Muscle strength of the shoulder and elbow flexors in the upper extremity and hip flexors in the lower extremities will be evaluated.
