Hands on treatment to relax the muscle involved in breathing along with exercises to strengthen the muscles supporting the lower back and abdomen compared with strengthening exercises of abdomen and back alone for pain and low back functions in young adults with low back pain of unknown cause

INTERVENTION: Intervention1: Diaphragmatic Myofascial Release with Core Stabilization Exercises: Participants in the interventional group will receive diaphragmatic myofascial release in combination with core stabilization exercises. Diaphragmatic myofascial release will be performed in crook‐lying position using sustained manual pressure over the subcostal region, particularly between the 7th and 10th ribs, coordinated with the participants breathing cycle. The technique will be performed bilaterally. Core stabilization exercises will include abdominal drawing‐in maneuver, bracing and progressive functional movement exercises. The intervention will be administered 3 sessions per week for 6 weeks, with each session lasting approximately 60 minutes. The total duration of this intervention is 6 weeks. Control Intervention1: Core Stabilization Exercises: Participants in the control group will receive core stabilization exercises alone. The exercise program will include activation of deep stabilizing muscles using the abdominal drawing‐in maneuver, followed by bracing and progressive functional movement patterns. Exercises will be performed in 1 3 sets, with 8 15 repetitions and contraction holds of 5 10 seconds, with progression based on participant tolerance and performance. The intervention will be administered 3 sessions per week for 6 weeks i.e. 18 sessions total, with each session lasting approximately 60 minutes. The total duration of the intervention will be si Xweeks. CONDITION: PRIMARY OUTCOME: 1.Numerical pain rating scale ; 2.Oswestry disability index ; 3. Lumbar range of motion using an inclinometer. ; 4. Core muscle endurance using plank endurance test. ; 5. Deep core muscle activation using pressure biofeedback unit.Timepoint: Baseline and 6 weeks. SECONDARY OUTCOME: NILTimepoint: INCLUSION CRITERIA: Subjects willing to participate in study and provide informed consent. Age group of 18 to 35 years. Both males and females will be recruited. Individuals with non specific low back pain of duration greater than 6 weeks.
