Reformer Pilates were performed, 2 days a week, for 4 weeks, in a total of 8 sessions (45 minutes each). The exercises of the Reformer Pilates were given as individual sessions by the physiotherapist. Reformer Exercises were explained by the physiotherapist in detail to understand the movement and starting position correctly, and the participants were then asked to perform the movements.

Hammock Yoga were performed, 2 days a week, for 4 weeks, in a total of 8 sessions (45 minutes each). Hammock Yoga were given as individual sessions by the physiotherapist.

Traditional mat exercises were performed, 2 days a week, for 4 weeks, in a total of 8 sessions (45 minutes each). The mat exercises were applied as a home program. The exercises were visually given with detailed explanations on a piece of paper, and they were checked by telephone every week.

Reformer Pilates exercises activates the lumbopelvic muscles and supports functional movement. Activated muscles support the spine and reduce the load on the spine by correcting the posture, helping the core muscles such as the abdomen and spine stay healthier by attaching them to a neutral pelvis Pilates consists of a sliding platform working with the help of a pulley system specific to the use, allowing the individual to apply certain resistances, and providing the opportunity to exercise sitting, standing, or lying down.

McGill Short Form was used at the beginning and end of the study to evaluate the qualitative characteristics of pain. The scale helps to learn about the sensory, emotional, and intensity component of pain. Fifteen items in the scale help define pain (11 sensory descriptors and 4 emotional descriptors). The participants were asked to rate their pain as 0=none, 1=less, 2=moderate, and 3=extreme, according to the intensity level. The total score was obtained by summing the scores given.

Disability (e.g., walking, sitting, standing, pain intensity, and sleeping) were evaluated with the Oswestry Disability Index, which consisted of 10 sections. A total score was obtained by scoring a Likert-type design ( 0-5 in each section). An increase in the score indicated an increased disability

The World Health Organization Quality of Life-Bref (WHOQOL-Bref) Questionnaire was used to evaluate the quality of life. The questionnaire has 5 sections (Psychological Health, Physical Health, General Health, Social Relations, and Environmental Health).An increase in the score indicated an increased Quality of Life.

A Visual Analog Scale was used to evaluate pain intensity. This scale is a straight horizontal line of fixed length, usually 100 mm. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.

The forward plank test was used to measure the control and endurance of the back/core stabilizing muscles.The aim of this test was to hold an elevated position for as long as possible. Start with the upper body supported off the ground by the elbows and forearms, and the legs straight with the weight taken by the toes. The hip was lifted off the floor creating a straight line from head to toe. As soon as the subject was in the correct position, the stopwatch was started and time was recorded
