Fascial exercises are a systematic set of movements and manual techniques that target the fascia-the body's connective tissue network-with the aim of improving or maintaining its elasticity, hydration, mobility, and functional integrity. These exercises seek to enhance gliding between fascial layers, reduce tissue restrictions, improve neuromuscular coordination, and alleviate chronic musculoskeletal pain.Fascia is not merely a passive structure; it functions as an active sensory organ containing proprioceptors, nociceptors, and mechanoreceptors.

This exercise system will first be taught to the patient by a physiotherapist, then a home brochure will be given and the patient will be given 14 days to practice it at home.

Individuals in this arm will do fascia exercises at home through a mobile application as home exercises. These exercises would be taught to the participant by the physiotherapist in the clinical setting and then the participant would be allowed to install a mobile application on their phone. The name of this mobile application is Fascia-M. This mobile application will be developed by the researcher of this study during the study process.

Within the scope of this study, lumbar stabilization exercises will be applied to a specific group of participants within a home-based exercise program. The program is structured to support individuals' activities of daily living, maintain spinal health and improve muscle balance in the lumbar region. Lumbar stabilization exercises consist of controlled movements that target the deep spinal stabilizer muscles (especially m. transversus abdominis and m. multifidus) and contribute to maintaining the spine in a neutral position.

Fascia exercises are taught by the physiotherapist in the clinical setting and if the exercises are performed incorrectly, intervention is made and the correct exercise is taught. At home, the individual is motivated and monitored with an exercise diary. He/she remembers the exercises from the home brochure.

Change in self-reported low back pain intensity as measured by the Visual Analog Scale (VAS). The VAS is a unidimensional pain assessment tool consisting of a 10 cm horizontal line anchored by "no pain" (0 cm) and "worst imaginable pain" (10 cm). Participants will mark their current pain level on the line. The distance (in cm) from the left end to the mark will be recorded as the pain score.

Change in lumbar functional disability assessed using the Oswestry Disability Index (ODI). The ODI consists of 10 sections measuring the degree of disability in daily living activities due to low back pain. Total scores range from 0% (no disability) to 100% (maximum disability).
