Lower back pain (LBP) is the single leading cause of disability globally, and in the Chandigarh Tricity — where prolonged sitting and poor lifting habits are endemic — it is among the most common reasons people visit a physiotherapist. Accurate diagnosis of the pain source — whether muscular, disc-related, sacroiliac joint, or nerve-based — is the most critical first step. Targeted physiotherapy combining spinal decompression, joint mobilisation, sciatica nerve care, and progressive core rehabilitation resolves the majority of LBP cases without surgery. Dr. Tarun Garg at PhysioNutra Clinic, Zirakpur offers in-clinic and home visit physiotherapy for lower back pain across Chandigarh, Mohali, Panchkula, Kharar, Baltana, and Dhakoli.

Lower back pain is not a single condition — it is a symptom that can arise from a wide range of structures within and around the lumbar spine and pelvis. The challenge for patients is that many of these sources produce overlapping symptoms: a strained lumbar muscle, an irritated sacroiliac joint, a compressed nerve root, and a degenerated disc can all produce similar-feeling pain in the same region of the lower back. This overlap is precisely why so many patients receive inadequate treatment — the wrong source is targeted, and the pain persists.
At PhysioNutra Clinic, every lower back pain assessment is built around identifying the specific structure generating symptoms, not simply treating the area that hurts. This distinction — between the pain location and the pain source — is what separates a treatment plan that achieves lasting resolution from one that provides only temporary relief. This guide walks through the most common causes of lower back pain, how each is accurately identified, and the targeted physiotherapy approaches that produce the best clinical outcomes for each.
Acute vs Chronic Lower Back Pain: Why the Distinction Matters
The terms acute and chronic do not simply describe how much a patient is suffering — they describe fundamentally different biological states that require different treatment priorities. Acute LBP (pain present for fewer than 6 weeks) is typically dominated by tissue inflammation, protective muscle guarding, and pain-driven movement restriction. The primary treatment goals are pain reduction, restoring safe movement patterns, and preventing the development of fear-avoidance behaviours that can convert acute pain into a chronic condition.
Chronic LBP (pain persisting beyond 12 weeks) involves a very different biological landscape: the original tissue injury may have resolved, but the pain has been maintained by muscular deconditioning, habitual movement compensations, postural loading patterns, and in many patients, central sensitisation — a state of heightened nervous system reactivity that amplifies pain signals from the lumbar region. Treating chronic LBP requires addressing all of these dimensions, not simply applying pain-relief modalities to a region that aches.
Between these two is the sub-acute phase (6–12 weeks) — a pivotal window. This is when the natural recovery curve plateaus and many patients either begin to improve rapidly with appropriate rehabilitation, or begin the transition toward chronicity through inadequate treatment, inactivity, or progressive fear of movement. Early physiotherapy intervention during the sub-acute phase is one of the highest-value clinical decisions a patient with persistent back pain can make.
The Six Most Common Sources of Lower Back Pain
Lumbar Muscle & Ligament Strain
The most prevalent cause of acute LBP — excessive mechanical load on the paraspinal muscles, thoracolumbar fascia, or posterior lumbar ligaments. Typically follows a sudden unguarded movement, heavy lifting, or an awkward sustained posture. Pain is localised, worsens with movement, and is clearly tender on direct palpation. Responds rapidly to soft tissue treatment and early active rehabilitation — most resolve within 2–4 weeks with appropriate physiotherapy and guided return to normal activity.
Lumbar Disc Herniation & Nerve Root Compression
Disc herniation occurs when the nucleus pulposus protrudes through a weakened section of the annulus fibrosus — most commonly at L4–L5 or L5–S1 — and contacts an adjacent nerve root. In addition to lower back pain, patients experience sharp, burning, or shooting leg pain (sciatica), leg tingling or numbness in a specific dermatomal distribution, and sometimes leg weakness. Clinical neurological testing, combined with selective movement assessment, identifies the affected level. Responds to targeted decompression and directional exercise.
Sacroiliac (SI) Joint Dysfunction
The sacroiliac joint is the junction between the sacrum and the ilium on each side of the pelvis. When this joint loses its normal movement dynamics — through hypermobility, hypomobility, or inflammation — it generates pain in the lower back, buttock, and sometimes into the posterior thigh that closely mimics lumbar disc and nerve pain. SI joint dysfunction is responsible for 15–25% of lower back pain presentations and is one of the most frequently missed diagnoses in clinical practice. Specific provocative tests and targeted pelvic stabilisation distinguish it from lumbar pathology.
Lumbar Facet Joint Pain
The zygapophyseal (facet) joints at each lumbar level guide and limit spinal movement, and when subjected to excessive compressive loading — through extension postures, lumbar hyperlordosis, or degenerative narrowing — they become a significant source of local back pain. Facet pain is classically worsened by back extension and rotation and relieved by forward bending. It is common in active individuals who load their spines into extension (weightlifters, footballers, labourers) and in patients with anterior pelvic tilt. Responds well to joint-unloading mobilisation and hip flexor flexibility work.
Piriformis Syndrome & Deep Gluteal Impingement
The sciatic nerve passes directly beneath — and in some individuals, through — the piriformis muscle deep in the gluteal region. When the piriformis becomes hypertonic or develops trigger points, it compresses the sciatic nerve, producing buttock pain and leg symptoms that are clinically indistinguishable from disc-related sciatica — sometimes called "pseudo-sciatica." Unlike true lumbar radiculopathy, piriformis syndrome does not produce lumbar movement limitation or positive neurological findings, and is treated primarily through deep gluteal soft tissue work and hip rotator strengthening rather than spinal decompression.
Postural LBP & Deconditioning Syndrome
The most underestimated cause of persistent lower back pain — particularly in the desk-working population of the Chandigarh Tricity — is sustained poor posture combined with progressive global deconditioning. Prolonged sitting in a posterior pelvic tilt flattens the lumbar lordosis, chronically strains the posterior ligamentous complex, inhibits the deep stabilising muscles (multifidus, transversus abdominis), and increases intradiscal pressure in a sustained, cumulative manner. Over months and years, the spine simply cannot tolerate the mechanical demands placed on it. Correction requires both postural retraining and progressive muscle rehabilitation — not imaging or injections.
- Cauda equina syndrome: New bladder or bowel dysfunction alongside lower back pain — a surgical emergency requiring immediate hospital attendance
- Saddle anaesthesia: Numbness around the inner thighs, perineum, or groin — requires same-day neurological evaluation
- Progressive leg weakness: Worsening motor deficit in the leg — loss of ankle dorsiflexion, knee extension, or hip flexion power
- Fever, unexplained weight loss, or night sweats with back pain: May indicate spinal infection or malignancy — requires full medical investigation before physiotherapy
- Back pain after significant trauma: Fall from height, road traffic accident, or impact in an older adult — possible vertebral fracture requiring imaging first
Diagnosing Lower Back Pain: The PhysioNutra Assessment
Dr. Tarun Garg uses a structured, evidence-based clinical assessment to identify the precise pain source before treatment begins. This takes approximately 45–60 minutes and includes a detailed pain history, postural and movement analysis, active and passive lumbar and hip range of motion testing, neurological screening of the lower limb (sensation, reflexes, muscle strength testing), and specific provocative tests for the sacroiliac joint, disc, and piriformis.
A critical component of every LBP assessment at PhysioNutra Clinic is the repeated movement evaluation — systematically testing lumbar flexion, extension, lateral flexion, and combined movements to identify directional preference. If symptoms centralise (move towards the lower back and away from the leg) with a specific movement direction, this identifies a directional preference and guides the exercise prescription with high precision. This movement-based classification removes guesswork from the treatment plan and significantly improves outcomes.
For patients where imaging has already been performed, MRI findings are interpreted in the clinical context of the patient's specific symptom pattern — a critical distinction, as many people in their 40s and above have disc changes on MRI that are not causing their current pain. Over-reliance on imaging findings without clinical correlation is one of the most common causes of inappropriate treatment selection for lower back pain.
Sacroiliac (SI) Joint Dysfunction: The Frequently Missed Diagnosis
Because SI joint pain closely mimics lumbar spine pathology, it deserves particular attention as a standalone topic. The sacroiliac joint bears the compressive loads transmitted from the upper body to the lower limbs and must simultaneously allow small but critical movements during walking, stair climbing, and load transfer. When this joint loses normal movement dynamics — too much movement (hypermobility, common post-pregnancy), too little movement (hypomobility), or inflammation (sacroiliitis) — the resulting pain is characteristically unilateral, located just below and medial to the posterior superior iliac spine, and often confused with disc-related or hip-related pain.
Classic SI Joint Symptoms
- One-sided lower back or deep buttock pain — rarely bilateral
- Pain crossing one side of the lower back into the groin or posterior thigh (rarely below the knee)
- Sharp catch when turning over in bed or rising from a chair
- Worsening pain when climbing stairs or walking on uneven surfaces
- Difficulty standing on one leg to dress or balance
- Pain relieved by lying with a pillow between the knees
- Aggravated by prolonged sitting asymmetrically or crossing legs
How We Confirm SI Joint Involvement
- FABER test (Flexion, Abduction, External Rotation) — positive if groin or SI pain reproduced
- Posterior pelvic pain provocation (P4 / thigh thrust) test — the most sensitive SI provocation test
- Gaenslen's test — shear stress applied to the SI joint in a split-leg position
- Distraction and compression tests — assess joint capsule and ligamentous irritation
- Gait observation — antalgic gait with pelvic drop on the affected side
- Lumbar movement assessment — confirms lumbar spine is NOT the primary pain source
Once SI joint dysfunction is confirmed, treatment is specific: graded sacroiliac joint mobilisation, pelvic floor activation and gluteus medius strengthening to restore dynamic pelvic stability, a temporary SI joint belt for acute load management, and a progressive return to full function. The outcomes for SI joint physiotherapy are excellent when the diagnosis is accurate — the majority of patients achieve full resolution within 6–10 weeks.
Physiotherapy Treatments for Lower Back Pain
Spinal Decompression Therapy
Mechanical intermittent lumbar traction creates a controlled distraction force that increases the space between lumbar vertebrae, reduces intradiscal pressure, widens the intervertebral foramina through which nerve roots exit, and promotes retraction of herniated disc material away from the nerve. Cycles of 30 seconds traction and 10 seconds rest are preferred over sustained traction as they optimise fluid exchange within the disc. This is the primary treatment modality for disc herniation with radiculopathy and foraminal stenosis causing true sciatica.
Joint Mobilisation & Manipulation
Graded oscillatory mobilisation applied to specific lumbar or sacroiliac joints restores restricted intersegmental movement, inhibits pain via neurophysiological gate-control mechanisms, and reduces protective muscle spasm. Graded Maitland technique (Grade I–II for acute/irritable pain, Grade III–IV for chronic joint stiffness) allows the intensity of mobilisation to be precisely matched to the patient's pain state and tissue presentation. Sacroiliac manipulation, under appropriate clinical conditions, produces immediate pain reduction and improved pelvic mechanics in appropriately selected patients.
Sciatic Nerve Mobilisation (Nerve Flossing)
When the sciatic nerve and its branches develop intraneural adhesions or mechanical sensitivity — as occurs in disc-related radiculopathy, piriformis syndrome, or post-surgical scarring — the nerve loses its normal capacity to slide freely through surrounding tissues during leg movement. Sciatic nerve mobilisation techniques alternately tension and release the nerve along its entire pathway from the lumbar root to the foot, reducing intraneural oedema, restoring neural tissue extensibility, and alleviating peripheral leg symptoms. Performed gently and progressively, nerve flossing is a core component of sciatica rehabilitation at every stage of recovery.
Directional Preference Exercise (McKenzie Method)
The McKenzie Mechanical Diagnosis and Therapy system uses a precise, systematic movement assessment to identify each patient's directional preference — the specific movement direction that centralises and reduces their pain. For the majority of disc-related LBP and sciatica, the direction of preference is lumbar extension (lying prone and pressing up), which promotes anterior migration of disc material and decompression of the posterior nerve root. For facet joint and stenosis presentations, the preference is often flexion-biased. McKenzie exercises are prescribed with a frequency and dosage (typically every 2 hours of waking) that far exceeds what is achievable in a clinic setting — making them a powerful home self-management tool.
Core & Pelvic Stability Rehabilitation
Regardless of the specific pain source, virtually all patients with recurrent or chronic LBP have some degree of deep stabiliser inhibition — the multifidus and transversus abdominis fail to provide adequate segmental spinal control during daily movements. Core rehabilitation at PhysioNutra Clinic begins with motor relearning of these specific muscles — not generic abdominal strengthening — before progressively integrating them into functional patterns: bridge, bird-dog, dead bug, Romanian deadlift, and finally sport- or occupation-specific loading. This rehabilitation is the single most important determinant of long-term pain-free function and non-recurrence.
Electrotherapy & Deep Tissue Release
TENS and Interferential Therapy (IFT) provide effective, non-pharmacological analgesia — particularly valuable during the acute and sub-acute phases when pain levels limit active exercise participation. Deep tissue massage, myofascial release, and trigger point therapy applied to the lumbar erector spinae, quadratus lumborum, gluteal muscles, and piriformis reduce hypertonic muscle guarding, improve regional circulation, and restore the tissue extensibility needed for effective joint mobilisation. These passive modalities are used strategically to enable active exercise — not as a substitute for it.
Lifting Mechanics: The Most Important Habit for Back Health
The single activity responsible for the greatest number of acute lower back injuries — and the greatest number of disc herniations — is lifting with a flexed, rotated lumbar spine under load. Most patients understand they "shouldn't twist when lifting," yet the movement that leads to injury rarely feels dramatic in the moment. It is the casual forward reach to pick up a bag, the quick rotation to place a heavy item on a shelf, the morning reach to the floor while still stiff — accumulated over a lifetime of habitual movement patterns.
- Set your spine first: Before any load is taken, establish a neutral lumbar position — slight natural arch, not flattened and not exaggerated. This is your spine-sparing position
- Hinge at the hips, not the lower back: All downward movement comes from flexing the hips and knees — the lumbar spine maintains its neutral position throughout. Think of the hips as the hinge point of a door; the door itself (your spine) stays rigid
- Brace your core before you lift: Take a breath in, gently engage your abdominals, and maintain this engagement throughout the lift. Do not hold your breath — breathe out steadily as you rise with the load
- Keep the load close: Every inch an object is held away from the body multiplies the compressive load on the lumbar discs by several times. Hold loads against your body whenever possible
- Rotate your whole body — never your spine: If you need to turn with a load, move your feet. Never rotate your lumbar spine while holding weight — this is the mechanism of the majority of significant disc injuries
- Respect morning stiffness: Lumbar discs re-hydrate and swell overnight. The disc and its annular fibres are at their most vulnerable in the first 30–60 minutes of the morning — avoid heavy lifting or deep forward bending immediately upon waking
A Practical Home Exercise Programme for Lower Back Pain
The exercises below represent a structured progressive programme for LBP. They are presented as a general educational guide — your physiotherapist will determine which exercises are appropriate for your specific diagnosis, and which should be modified or avoided based on your clinical presentation. Do not self-prescribe based on this guide alone.
Phase 1 — Pain Relief & Safe Movement (Week 1–2)
Goals: Reduce Pain, Begin Gentle Mobilisation, Activate Deep Stabilisers
- Pelvic Clock (Supine): Lying on your back, knees bent — gently rock your pelvis in small circles, imagining a clock face on your lower back. 10 full clock rotations. Restores sacroiliac and lumbar mobility without generating compressive load. Particularly effective for both SI joint dysfunction and lumbar stiffness in the acute phase.
- Abdominal Hollowing (ADIM): Lying on your back, gently draw the navel inward and upward without bracing or holding the breath. Hold 8–10 seconds, 10 repetitions, 3–4 times per day. This isolated transversus abdominis activation is the foundational deep stabiliser exercise — the starting point of every LBP rehabilitation programme.
- Knee-to-Chest Hold: Supine, bring one knee to the chest and hold 30 seconds, alternate sides, 3 repetitions each. Provides immediate posterior joint and lumbar erector relief and is safe across almost all LBP presentations in the acute phase.
- Prone Lying (if tolerated): Simply lying face down on a firm surface with a pillow under the abdomen for 5–10 minutes. For patients with disc-related pain, this position begins to restore natural lumbar lordosis and initiates the extension-preference retraining process before active exercises are introduced.
- Short-arc Walking: 10–15 minutes of unhurried walking on flat surfaces, 2–3 times daily. Walking stimulates the rhythmic compressive-decompressive cycle that drives nutrient exchange into avascular lumbar discs, activates the deep stabilisers through gentle proprioceptive loading, and reduces the fear-avoidance cycle that accelerates transition to chronicity.
Phase 2 — Stability Building & Strengthening (Weeks 2–6)
Goals: Rebuild Multifidus and Transversus Abdominis Endurance, Restore Pelvic Stability
- Gluteal Bridge: Supine, knees bent, feet flat — drive through the heels to raise the pelvis until a straight line forms from knees to shoulders. Hold 5 seconds, lower slowly, 3 sets of 15. Strengthens gluteus maximus and hamstrings, reduces anterior shear forces on the lumbar spine, and corrects the posterior chain weakness that is almost universally present in chronic LBP patients.
- Bird-Dog: On hands and knees in a neutral spine position — extend the opposite arm and opposite leg simultaneously, holding for 8 seconds. 3 sets of 10 each side. The most clinically validated lumbar stabilisation exercise — co-activates multifidus, transversus abdominis, and gluteal muscles in a functional, low-compression pattern.
- Side-Lying Hip Abduction (Clamshell): Lying on the side, hips at 45° — raise the top knee without rolling the pelvis backward. 3 sets of 20. Strengthens gluteus medius, which is critical for sacropelvic stability during walking — its weakness is one of the primary contributors to both SI joint dysfunction and lumbar facet overload.
- Hip Flexor Stretch (Kneeling): Half-kneeling position — shift the pelvis forward until a stretch is felt in the front of the hip. Hold 45 seconds, 3 repetitions each side. Chronically tight iliopsoas muscles maintain an anterior pelvic tilt that continuously compresses lumbar facet joints and increases posterior disc tension — this is the single most neglected flexibility component in LBP rehabilitation for sedentary patients.
- Piriformis Stretch (Figure-4): Lying on the back, place the ankle of one leg across the opposite knee and gently draw the lower leg towards the chest until a deep gluteal stretch is felt. Hold 40 seconds, 3 repetitions each side. Essential for patients with piriformis-related pseudo-sciatica and for general hip rotator mobility that supports SI joint function.
Phase 3 — Functional Recovery & Prevention (Weeks 6–12)
Goals: Full Functional Capacity, Return to Work / Sport, Lifelong Self-Management
- Dead Bug Progressions: Supine, arms vertical, hips and knees at 90° — lower opposite arm and leg toward the floor simultaneously while maintaining lumbar neutral and full abdominal engagement. This anti-extension core challenge directly trains the motor pattern needed to maintain spinal protection during daily activities.
- Romanian Deadlift (Hip Hinge Pattern): Standing with a light resistance, hinge at the hips — spine rigid and neutral — lowering the weight toward the floor, then returning to standing via hip extension. 3 sets of 12. This is the fundamental spine-sparing functional movement pattern for all lifting activities. It is the most important movement to master and maintain for the remainder of the patient's life.
- Single-Leg Balance Progressions: Barefoot single-leg standing for 30–60 seconds, progressing to eyes-closed, then with gentle arm movements. Trains the gluteus medius and deep hip stabilisers that prevent pelvic drop during walking — a key ongoing stress on both the lumbar spine and sacroiliac joint with every step taken.
- Walking Programme — Progressive: Build from 20 to 45+ minutes of brisk walking per day, 5–6 days per week. Walking remains the most evidence-supported, sustainable physical activity for long-term LBP management — it reduces central sensitisation, maintains disc health through rhythmic loading, builds cardiovascular fitness, and provides neurological benefits that cannot be replicated by any single exercise.

Patient Success Stories
Real Recoveries at PhysioNutra Clinic
Simranjeet K., Age 28 (Acute Disc Herniation with Sciatica, Mohali): "I woke up one morning unable to straighten up and with electric pain shooting down my left leg. I was terrified I'd need surgery. Dr. Tarun assessed me properly and started spinal traction along with McKenzie extension exercises. Within five days the leg pain had pulled back to just my lower back — he said this was exactly what we wanted to see. By week eight I was back to the gym completely pain-free. No injections, no surgery."
Harpreet B., Age 42 (Sacroiliac Joint Dysfunction, Panchkula): "I had one-sided lower back and groin pain for over a year. Multiple X-rays and MRIs showed nothing significant. Everyone treated my lumbar spine but nothing worked. Dr. Tarun was the first person to specifically test my SI joint and diagnose it correctly. Six weeks of targeted pelvic physiotherapy and I have no pain — I wish I had found him a year earlier."
Neha S., Age 38 (Postural LBP with Deconditioning, Zirakpur — Home Visit Patient): "I have two young children and couldn't get to a clinic easily. Dr. Tarun's team came to my home and were able to see exactly how I was sitting, lifting the children, and sleeping — and corrected everything. The home visit made such a difference to my understanding of what was causing my back pain. After eight weeks of home-based physiotherapy I am completely pain-free and know how to keep it that way."
