Conditions
Summary
Chronic low back pain (CLBP) is a multifactorial condition influenced by physical, psychological, and social factors. Conventional physical therapy primarily targets biomechanical impairments, often neglecting psychosocial contributors that perpetuate chronic pain and disability. This randomized comparative clinical trial aims to evaluate the effectiveness of Biopsychosocial (BPS) model-based care versus routine physical therapy on pain, disability, psychosocial outcomes, and inflammatory response among adults with CLBP. A total of \_\_\_ participants with CLBP (≥12 weeks) will be randomly allocated into two groups: Routine Physical Therapy Group - receiving baseline hot pack and TENS, stretching (hamstring, gluteal, iliopsoas, and lumbar extensors), and strengthening/stabilization exercises (planks, abdominal bracing, gluteal isometrics, and bridging). BPS Model-Based Care Group - receiving the same baseline treatment plus Maitland mobilization (Grade I-II central PA), sciatic nerve slider, abdominal bracing, graded functional activity, cognitive behavioral therapy (CBT), pain neuroscience education (PNE), guided imagery, and group-based functional exercise therapy. Primary outcome measures include Pain Self-Efficacy, Oswestry Disability Index (ODI), and C-Reactive Protein (CRP). A secondary variable, Perceived Social Support, will assess the social component of recovery. This study hypothesizes that the BPS model-based care will produce superior improvements in pain self-efficacy, functional disability, and inflammatory markers compared to routine therapy, supporting the integration of biopsychosocial rehabilitation in chronic low back pain management.
Eligibility
Inclusion Criteria4
- Diagnosed with non-specific chronic low back pain (pain persisting for more than 12 weeks).
- Pain intensity score of ≥3 on the Visual Analog Scale (VAS).
- Able to read and understand the study instructions and questionnaires (e.g., SF-36, Oswestry Disability Index).
- Not undergoing any current structured physiotherapy or psychological treatment specifically for low back pain.
Exclusion Criteria8
- o History of specific spinal pathology (e.g., spinal fracture, tumor, infection, or inflammatory diseases like ankylosing spondylitis).
- Presence of neurological deficits (e.g., radiculopathy, cauda equina syndrome).
- Previous lumbar spine surgery.
- Current diagnosis of major psychiatric illness (e.g., severe depression, psychosis) that may interfere with participation.
- Pregnancy or within 6 months postpartum.
- Ongoing treatment with systemic corticosteroids or other medications affecting musculoskeletal health.
- Participation in another clinical trial within the past 3 months.
- Any other medical condition deemed by the investigator to contraindicate participation in the study.

Interventions
Participants receive a multimodal physical therapy program integrating physical, psychological, and social dimensions of care. Each session lasts 45 minutes, conducted three times per week for the four weeks. The intervention includes: Baseline modalities: Electrical hot pack (10 min) and TENS (10 min, 80-100 Hz, 100 µs) for pain relief. Manual therapy: Maitland central postero-anterior mobilizations (Grade I-II, 3 × 60 s). Neural mobilization: Sciatic nerve slider, 2 sets × 10 repetitions. Exercise therapy: Abdominal bracing, gluteal activation, graded functional activities, progressed by FITT principles. Psychological education: Cognitive Behavioral Therapy (CBT) and Pain Neuroscience Education (PNE) modules targeting fear-avoidance beliefs, catastrophizing, and maladaptive pain perceptions. Guided imagery and relaxation: Short sessions for body awareness and movement confidence. Social component: Group exercise sessions (3 to 4 participants) to encourage peer interaction.
Participants in the control group will receive standard physical therapy for chronic low back pain, focusing on pain relief, flexibility, and core/lower limb strengthening. Each session lasts 45 minutes, three times per week for four weeks. Baseline modalities include an electrical hot pack (10 min) and TENS (10 min; 80-100 Hz, 100 µs). Stretching targets the hamstrings, glutei, iliopsoas, and lumbar extensors (20-30 s × 3-5 reps). Strengthening and stabilization involve abdominal bracing, gluteal isometrics, bridging, and planks, progressed per FITT principles (10-15 reps, 40-60% effort). Brief patient education covers ergonomics, posture, activity modification, home exercises, and strategies for managing flare-ups. No psychological or social interventions are included.
