Sacral bone pain, an often debilitating and complex condition, affects a significant number of individuals, manifesting with a variety of symptoms and intensities. Located at the base of the spine, the sacrum is a crucial element for pelvic stability and the transmission of load between the trunk and lower limbs. Its strategic position and multiple connections make it susceptible to various problems, which can generate deep and persistent pain, often difficult to pinpoint precisely. Understanding the underlying causes, diagnostic methodologies, and therapeutic options, particularly physiotherapy, is fundamental for effective management of this condition. This article aims to explore sacral bone pain in detail, providing a comprehensive guide based on decades of clinical experience and the latest scientific evidence.

Anatomy and Function of the Sacrum

The sacrum is a triangular bone structure, composed of five fused sacral vertebrae (S1-S5), located between the two iliac bones of the pelvis and the fifth lumbar vertebra (L5). This robust structure forms the posterior part of the pelvis and articulates with:

For a complete overview, see the comprehensive guide to back pain and spine.

• Superiorly: With the fifth lumbar vertebra (L5) via the lumbosacral joint.
• Laterally: With the iliac bones through the two sacroiliac joints (SIJ), which are crucial for pelvic stability and mobility.
• Inferiorly: With the coccyx.

The main function of the sacrum is to provide a solid base for the spine, distribute body weight to the lower limbs, and protect the pelvic organs and sacral nerve roots. The sacroiliac joints, although having limited movement, are essential for absorbing shocks and allowing small adjustments during walking and other activities. The stability of these joints is ensured by a complex system of powerful ligaments (anterior, posterior, interosseous, sacrotuberous, and sacrospinous) and surrounding musculature, including the gluteal muscles, piriformis, multifidus, and transversus abdominis.

The rich innervation of the sacral region, derived from the sacral plexus, explains the potential radiation of pain to the buttocks, thighs, and even the feet, sometimes mimicking sciatica. The anatomical and functional complexity of this region makes the diagnosis and treatment of sacral bone pain a challenge requiring a multidisciplinary approach and thorough evaluation.

Symptoms of Sacral Bone Pain

Sacral bone pain manifests with a variety of symptoms, whose intensity and localization can vary significantly from individual to individual and depending on the underlying cause. Understanding these symptoms is the first step towards an accurate diagnosis.

Localization and Characteristics of Pain

The most common symptom is pain localized in the lower back, specifically in the gluteal region, often described as deep, dull, and persistent. However, the pain can also be acute, sharp, or burning.

• Typical Localization: Generally perceived in the lower back, just above the buttocks, often unilaterally (on one side of the sacrum) but sometimes bilaterally. It can be difficult to pinpoint the exact source of the pain with a finger.
• Radiation: The pain can radiate towards the buttock, groin, posterior or lateral thigh, and, in rare cases, down to the knee or foot. This radiation can be confused with sciatica, but it usually does not follow a specific dermatome as in the case of lumbar radiculopathy.
• Quality of Pain: Can vary from a dull, constant ache to acute, sharp pain, sometimes accompanied by burning or tingling sensations.

Aggravating and Alleviating Factors

Sacral bone pain is often influenced by certain positions or activities:

• Aggravation:

• Prolonged sitting: Especially on hard or soft surfaces, or in asymmetrical positions (e.g., with a wallet in the back pocket).

• Prolonged standing: Maintaining the same position for long periods.

• Transition from sitting to standing: The transitional movement can be particularly painful.

• Climbing stairs or walking on uneven terrain: Requires greater pelvic stability.

• Unilateral loading: Bearing weight on one leg only.

• Trunk flexion or extension: Certain movements can increase pressure on the sacroiliac joint.

• Trunk rotation: Movements involving pelvic torsion.

• High-impact activities: Running, jumping.

• During or after pregnancy: Due to ligamentous laxity.
• Alleviation:

• Rest in a supine position (lying on the back).

• Frequent changes in position.

• Application of heat or ice.

Associated Symptoms

In some cases, sacral bone pain may be accompanied by other symptoms:

• Stiffness: Especially in the morning or after periods of inactivity.
• Muscle weakness: Rarely, if there is significant nerve compression.
• Tingling or numbness: In areas of pain radiation.
• Feeling of instability: In the pelvis or lower back.
• Difficulty sleeping: Due to pain.
• “Red Flag” Symptoms: It is crucial to pay attention to symptoms that could indicate more serious conditions, such as:

• Loss of bladder or bowel control.

• Progressive weakness in the lower limbs.

• Saddle anesthesia (numbness in the perineal and genital area).

• Fever, unexplained weight loss, night sweats.

• Night pain that does not improve with rest.

These symptoms require immediate medical evaluation.

A detailed description of symptoms to your doctor or physical therapist is crucial for correctly guiding the diagnostic and therapeutic process.

Causes of Sacral Bone Pain

Sacral bone pain can stem from a wide range of conditions, which may involve the sacroiliac joint itself, surrounding structures, the lumbar spine, or be referred from other areas of the body. An accurate diagnosis requires identifying the specific cause.

Sacroiliac Joint (SIJ) Dysfunction

Sacroiliac joint dysfunction is one of the most common causes of sacral bone pain, estimated to be responsible for 15-30% of chronic low back pain cases. Despite its importance, diagnosis can be complex due to the variability of symptoms and overlap with other conditions. Dysfunction can manifest as:

• Hypermobility (excessive mobility): Occurs when the ligaments stabilizing the joint are loose or damaged, causing instability. This can happen as a result of:

• Trauma: Falls on the buttocks, car accidents, sudden movements.

• Pregnancy and postpartum: Hormones (relaxin) increase ligamentous laxity to prepare the pelvis for childbirth, making the joint more vulnerable. The trauma of childbirth itself can also contribute.

• Leg length discrepancy: Can create asymmetrical stress on the joint.

• Muscle imbalances: Weakness of core stabilizing muscles or gluteal muscles.
• Hypomobility (reduced mobility): Occurs when the joint is too stiff or “locked,” limiting movement and causing pain. Causes may include:

• Osteoarthritis: Degeneration of articular cartilage.

• Chronic inflammation: As in spondyloarthritis.

• Prolonged incorrect posture: Which can lead to stiffness.

• Muscle imbalances: Excessive tension in muscles such as the piriformis or hip flexors.

Lumbar Spine Pathologies

Often, pain perceived in the sacral region can originate from the lumbar spine, given its close proximity and nerve connections.

• L5-S1 disc herniation: Compression of the S1 nerve root can cause pain radiating into the sacral region and down the leg (sciatica).
• Lumbar spinal stenosi (restringimento del canale vertebrale o vascolare)s: A narrowing of the spinal canal that can compress nerves, causing pain, numbness, and weakness, often worsened by standing and relieved by forward flexion.
• Spondylolisthesis: The slipping of one vertebra over another (often L5 over S1) can cause instability and nerve irritation.
• Vertebral osteoarthritis (spondyloarthrosis): Degeneration of the lumbar facet joints can refer pain to the sacral region.
• Facet joint syndrome: Inflammation of the small joints between the vertebrae.

Direct Trauma

• Stress fractures: Can occur in the sacrum in athletes (especially runners) or individuals with osteoporosis, due to repetitive loads or reduced bone density.
• Traumatic fractures: Direct falls on the buttocks or car accidents can cause fractures of the sacrum or coccyx.

Inflammation and Arthritis

• Spondyloarthritis: A group of chronic inflammatory diseases primarily affecting the spine and sacroiliac joints. Examples include:

• Ankylosing Spondylitis: Characterized by inflammation and progressive fusion of the vertebrae and SIJ.

• Psoriatic Arthritis: Associated with cutaneous psoriasis.

• Reactive Arthritis (Reiter’s syndrome): Develops after an infection.

• Enteropathic Arthritis: Associated with inflammatory bowel diseases (e.g., Crohn’s Disease, Ulcerative Colitis).
• Infectious Sacroiliitis: Rare, but serious, caused by bacterial infections reaching the joint.

Muscular and Ligamentous Causes

• Piriformis syndrome: The piriformis muscle, located in the buttock, can compress the sciatic nerve (or irritate local nerves) if it is contracted or inflamed, causing pain that radiates from the sacral region down the leg.
• Muscle tension: Contractions or spasms of the gluteal muscles, hamstrings, or pelvic floor muscles can refer pain to the sacrum.
• Sacroiliac ligaments: Injuries or inflammation of the ligaments that stabilize the sacroiliac joint.

Visceral or Referred Causes

Pain in the sacral region can be a referred symptom from internal organs, making diagnosis more complex.

• Gynecological problems: Endometriosis, uterine fibroids, pelvic inflammatory disease, ovarian cysts.
• Urological problems: Interstitial cystitis, prostatitis.
• Gastrointestinal problems: Inflammatory bowel diseases (IBD), diverticulitis, irritable bowel syndrome.
• Tumors: Primary (e.g., chordoma) or metastatic tumors involving the sacrum or nearby structures.
• Infections: Osteomyelitis of the sacrum.

Neurological Causes

• Pudendal nerve neuropathy: Compression or irritation of the pudendal nerve, which can cause pain in the perineal, genital, and anorectal region, sometimes perceived as sacral pain.
• S1 Radiculopathy: As mentioned, compression of the S1 nerve root can cause symptoms in the sacral region.

Psychosocial Factors

Stress, anxiety, depression, and psychological factors may not be the primary cause of pain, but they can amplify pain perception, influence its chronification, and affect treatment response.

Given the multiplicity of possible causes, the importance of a thorough medical and physiotherapy evaluation is evident to identify the specific origin of the pain and establish the most appropriate therapeutic path.

Diagnosis of Sacral Bone Pain

Diagnosing sacral bone pain is often a challenge, given the overlap of symptoms with other conditions and the anatomical complexity of the region. A systematic approach combining a detailed medical history, a thorough physical examination, and, if necessary, instrumental tests, is fundamental to identify the underlying cause.

Thorough Medical History

The first step is an accurate collection of the patient’s clinical history. Your doctor or physical therapist will ask specific questions regarding:

• Pain characteristics: Precise localization, radiation, quality (dull, acute, burning), intensity (VAS scale).
• Triggering and aggravating factors: Activities, positions, movements that increase or decrease pain.
• Alleviating factors: What relieves the pain.
• Onset: Acute (trauma) or gradual.
• Duration and frequency: Whether the pain is constant, intermittent, chronic.
• Previous trauma: Falls, accidents.
• Previous surgeries: To the spine or pelvis.
• Concomitant medical conditions: Arthritis, inflammatory bowel diseases, osteoporosis, gynecological/urological problems.
• Medications taken: Painkillers, anti-inflammatories.
• Associated symptoms: Numbness, tingling, weakness, urinary/bowel problems (warning signs).
• Lifestyle: Level of physical activity, type of work, postural habits.

Physical Examination

The physical examination is crucial for evaluating the posture, mobility, and function of the lumbosacral and pelvic region.

• Inspection and Palpation:

• Assessment of posture in standing and sitting.

• Search for pelvic or spinal asymmetries.

• Palpation of the sacrum, sacroiliac joints, ligaments, and surrounding muscles (e.g., piriformis, gluteal muscles) to identify areas of tenderness or tension.
• Assessment of Range of Motion (ROM):

• Active and passive movements of the lumbar spine and hips to identify limitations or pain.
• Sacroiliac Joint Provocation Tests: A series of specific tests, performed by the clinician, to reproduce pain and assess the stability and mobility of the SIJ. A test is considered positive if it reproduces the patient’s typical pain. Examples include:

• Distraction Test: Outward pressure on the anterior superior iliac spines.

• Compression Test: Inward pressure on the posterior superior iliac spines.

• Gaenslen’s Test: Flexion of one hip and hyperextension of the other, with the patient supine.

• Thigh Thrust Test (or Pushing): Axial pressure along the femur with the hip flexed to 90 degrees.

• FABER Test (Flexion, Abduction, External Rotation): Flexion, abduction, and external rotation of the hip.

• The positivity of at least 3-4 of these tests increases the likelihood of SIJ dysfunction as the source of pain.
• Neurological Evaluation:

• Muscle strength tests, cutaneous sensation, and deep tendon reflexes to rule out or confirm radiculopathy or other neurological problems.
• Muscle Length Tests: Assessment of tension in muscles such as the piriformis, hamstrings, hip flexors.

Instrumental Examinations

Instrumental examinations are not always necessary, but can be useful to confirm a diagnosis, rule out other pathologies, or identify the specific cause when the clinical examination is inconclusive.

• X-ray (RX): Useful for visualizing bone structure, ruling out fractures, congenital anomalies, or advanced signs of osteoarthritis or spondyloarthritis (e.g., sacroiliitis).
• Magnetic Resonance Imaging (MRI): The most sensitive examination for evaluating soft tissues (muscles, ligaments, intervertebral discs), inflammation (bone edema in acute sacroiliitis), disc herniations, tumors, or infections. It is often the examination of choice for SIJ evaluation.
• Computed Tomography (CT): Provides detailed images of bone structures, useful for complex fractures or for better visualization of articular surfaces.
• Bone scintigraphy: Can detect areas of increased bone metabolism, indicating stress fractures, infections, tumors, or inflammation.
• Electromyography (EMG) and Nerve Conduction Velocity (NCV): Can be used to evaluate nerve and muscle function, useful in cases of suspected radiculopathy or neuropathy.
• Diagnostic Infiltrations: The injection of a local anesthetic (with or without corticosteroids) directly into the sacroiliac joint or a specific nerve (e.g., lateral sacral nerve branches) under radiographic or ultrasound guidance. If the pain significantly reduces after the infiltration, this confirms that the infiltrated area is the source of the pain. This is considered the “gold standard” for diagnosing SIJ pain.

Differential Diagnosis

It is fundamental to distinguish sacral bone pain from other conditions that may present similar symptoms, such as:

• Lumbar spine pathologies (disc herniation, stenosis, spondylolisthesis).
• Piriformis syndrome.
• Referred hip pain (hip osteoarthritis, trochanteric bursitis).
• Referred pain from pelvic or abdominal organs.
• Coccyx fractures.

Only through careful evaluation and a targeted diagnostic process is it possible to establish the precise cause of sacral bone pain and plan the most effective treatment.

Physiotherapy for Sacral Bone Pain

Physiotherapy represents the fundamental pillar in the conservative treatment of sacral bone pain, with the aim of reducing pain, restoring function, improving stability, and preventing recurrence. The physiotherapy approach is always individualized, based on the specific diagnosis, patient characteristics, and pain phase (acute, subacute, chronic).

Objectives of Physiotherapy Treatment

• Pain and Inflammation Reduction: Manage acute symptoms to allow the patient to actively participate in the rehabilitation program.
• Restoration of Joint Mobility: Normalize the movement of the sacroiliac joints and lumbar spine, both in cases of hypomobility and hypermobility.
• Improvement of Pelvic and Core Stability: Strengthen the muscles that support the pelvis and spine.
• Correction of Muscle Imbalances: Stretch tight muscles and strengthen weak ones.
• Postural and Movement Re-education: Teach the patient correct postures and efficient movement patterns to reduce stress on painful structures.
• Recurrence Prevention: Provide the patient with the tools and knowledge to self-manage the condition and prevent future pain episodes.

Phases of Physiotherapy Treatment

1. Acute Phase (Pain and Inflammation Management)

In this phase, the primary goal is to alleviate pain and reduce inflammation.

• Relative Rest: Avoid activities that aggravate pain, but maintain a certain level of movement to prevent stiffness.
• Instrumental Physical Therapies: Can be used to modulate pain and inflammation. The effectiveness of some of these therapies may vary, and their application must be based on evidence and clinical experience.

• TENS (Transcutaneous Electrical Nerve Stimulation): For pain control.

• Ultrasound: To reduce inflammation and promote tissue healing.

• Laser Therapy: With anti-inflammatory and biostimulating properties.

• Tecar Therapy (Capacitive Resistive Energy Transfer): To stimulate reparative processes and reduce pain.

• Cryotherapy (Ice): In cases of acute inflammation.

• Thermotherapy (Heat): To relax tense muscles.
• Gentle Mobilizations: Very gentle manual techniques to maintain or regain a minimum of mobility without causing pain.
• Patient Education: Explain the nature of the pain, reassure, and provide advice on how to manage daily activities so as not to aggravate the condition.

2. Subacute and Chronic Phase (Function Recovery and Prevention)

Once acute pain is under control, the focus shifts to regaining full function and prevention.

• Manual Therapy:

• Joint Mobilizations and Manipulations: The physical therapist can use specific techniques to restore normal mobility of the sacroiliac joints and lumbar spine. This may include low-velocity mobilizations and high-velocity, low-amplitude (HVLA) manipulations, if indicated and appropriate.

• Myofascial Release Techniques: To reduce tension and muscle spasms in areas such as the piriformis, gluteal muscles, iliopsoas, and lumbar muscles.

• Therapeutic Massage: To improve circulation, reduce muscle tension, and alleviate pain.

• Muscle Energy Techniques (MET): Utilize the patient’s muscle contractions to improve joint mobility and reduce muscle tension.

• Therapeutic Exercises: Form the core of the rehabilitation program and are essential for long-term recovery. They must be progressive and specific to the patient’s needs.

• Stretching Exercises: To lengthen muscles that tend to shorten and create imbalances, such as:

• Piriformis: Crucial for alleviating nerve compression and improving SIJ mobility.

• Hamstrings (posterior thigh muscles).

• Hip flexors (iliopsoas).

• Lumbar muscles.

• Strengthening Exercises: To stabilize the pelvis and spine, focusing on:

• Core Muscles: Transversus abdominis, multifidus, internal and external obliques. A strong core is fundamental for lumbopelvic stability.

• Gluteal Muscles: Gluteus medius, minimus, and maximus, essential for pelvic stability during walking and loading.

• Pelvic Floor Muscles: Often overlooked, but vital for pelvic stability, especially in women and during pregnancy.

• Motor Control and Postural Re-education Exercises: To improve coordination, body awareness, and the ability to maintain correct postures during daily activities.

• Sacroiliac Stability Exercises: Specific to improve joint cohesion, often through isometric or low-load exercises that activate deep stabilizing muscles.

• Global Postural Re-education (GPR) or Similar Methods: Approaches that consider the body as a single muscular chain, seeking to correct postural dysfunctions that can contribute to sacral pain.

• Patient Education and Lifestyle Modifications:

• Ergonomics: Advice on how to sit, stand, lift weights, and sleep in a way that reduces stress on the sacrum.

• Pain Management: Strategies for self-managing pain and recognizing warning signs.

• Physical Activity: Promote regular and balanced physical activity, avoiding movements that aggravate pain.

• Hydration and Nutrition: General advice for optimal well-being.

• Functional Taping or Pelvic Belt: In some cases of SIJ hypermobility, the temporary use of functional taping or a pelvic belt can provide support and reduce pain, allowing the patient to perform strengthening exercises with greater comfort.

The effectiveness of physiotherapy for sacral bone pain is supported by numerous pieces of evidence that highlight its central role. Collaboration between the patient and their physical therapist is essential for successful treatment, which requires commitment and consistency.

Specific Exercises for Sacral Bone Pain

Exercises are a fundamental component of physiotherapy for sacral bone pain. They aim to improve mobility, flexibility, strength, and stability of the lumbosacral and pelvic region. It is crucial that these exercises are performed correctly and under the guidance of a physical therapist, who can adapt them to the patient’s specific needs and conditions.

Before starting any exercise program, it is important to consult a healthcare professional to ensure they are appropriate for your condition.

1. Mobility Exercises

These exercises help maintain or restore gentle movement of the sacrum and lumbar spine.

• Knees to Chest (Single/Double Knee to Chest):

• Position: Lie on your back (supine), with knees bent and feet flat on the floor.

• Execution:

• Slowly bring one knee towards your chest, grasping it with your hands and gently pulling it. Hold the position for 20-30 seconds. Repeat 3-5 times per leg.

• Then, bring both knees to your chest, grasping them and gently pulling them. Hold for 20-30 seconds. Repeat 3-5 times.

• Benefits: Stretches the lower back and gluteal muscles, improves lumbar flexibility.

• Supine Trunk Rotations:

• Position: Lie on your back, knees bent, feet flat on the floor, arms open in a cross.

• Execution: Keeping your knees together, slowly let them fall to one side, keeping your shoulders on the floor. Hold the position for a few seconds, then return to the center and repeat on the other side. Perform 10-15 repetitions per side.

• Benefits: Improves mobility of the lumbar spine and sacroiliac joints.

• Cat-Cow:

• Position: On all fours, hands under shoulders and knees under hips.

• Execution:

• Cat: Inhale, arch your back upwards (like a stretching cat), lowering your head and contracting your abdominals.

• Cow: Exhale, lower your back downwards, lifting your head and pelvis.

• Slowly alternate between the two positions for 10-15 repetitions.

• Benefits: Improves spinal flexibility and coordination.

2. Stretching Exercises

These exercises are essential for releasing muscle tension that can contribute to sacral pain.

• Piriformis Stretch:

• Position 1 (Supine): Lie on your back, knees bent, feet flat on the floor. Place the ankle of the leg to be stretched on the opposite knee (forming a “4”). Grasp the thigh of the supporting leg and gently pull it towards your chest. Feel the stretch in the glute. Hold for 30 seconds, 3-5 repetitions per side.

• Position 2 (Seated): Sit on a chair, place the ankle of the leg to be stretched on the opposite knee. Lean your torso forward, keeping your back straight, until you feel the stretch in the glute. Hold for 30 seconds, 3-5 repetitions per side.

• Benefits: Releases tension in the piriformis muscle, which can irritate the sciatic nerve or contribute to SIJ dysfunction.

• Hamstring Stretch:

• Position: Lie on your back. Lift one straight leg upwards. Grasp the back of the thigh or calf and gently pull the leg towards you, keeping the knee as straight as possible.

• Execution: Hold for 30 seconds, 3-5 repetitions per leg.

• Benefits: Improves flexibility of the hamstrings, which can influence pelvic posture.

• Hip Flexor Stretch:

• Position: Kneel on a mat, with one leg forward bent at 90 degrees and the other leg back with the knee on the floor.

• Execution: Shift your pelvis forward, keeping your torso upright, until you feel the stretch in the front of the hip of the back leg. Hold for 30 seconds, 3-5 repetitions per side.

• Benefits: Releases tension in the hip flexors, which can pull the pelvis forward and increase stress on the sacrum.

3. Strengthening and Stability Exercises

These exercises are fundamental for stabilizing the pelvis and spine, reducing the load on the sacrum.

• Glute Bridge:

• Position: Lie on your back, knees bent, feet flat on the floor hip-width apart.

• Execution: Contract your glutes and slowly lift your pelvis off the floor until your body forms a straight line from your shoulders to your knees. Hold the position for 5-10 seconds, then slowly lower. Perform 10-15 repetitions.

• Benefits: Strengthens the glutes and core stabilizing muscles.

• Bird-Dog:

• Position: On all fours, hands under shoulders and knees under hips. Keep your back straight and core engaged.

• Execution: Simultaneously lift one arm and the opposite leg, extending them in line with your body, keeping your pelvis stable and without rotating. Hold for 5-10 seconds, then slowly return to the starting position. Perform 8-12 repetitions per side.

• Benefits: Improves core stability and coordination.

• Clamshell:

• Position: Lie on your side, knees bent at 90 degrees, feet together.

• Execution: Keeping your feet together, lift your top knee upwards, opening your legs like a clamshell. Contract your glute. Do not rotate your pelvis. Slowly lower. Perform 15-20 repetitions per side.

• Benefits: Strengthens the gluteus medius, a key muscle for pelvic stability.

• Plank:

• Position: Supported on your forearms and toes, keeping your body straight like a plank, without arching or lowering your back.

• Execution: Hold the position for as long as possible, focusing on core contraction. Start with 20-30 seconds and gradually increase.

• Benefits: Strengthens all core muscles, improving overall stability.

• Pelvic Floor Exercises (Kegel):

• Position: Sitting, lying down, or standing.

• Execution: Contract your pelvic floor muscles (as if trying to stop the flow of urine or hold back gas) and lift them upwards. Hold for 5-10 seconds, then completely relax. Perform 10-15 repetitions, 3 times a day.

• Benefits: Improves pelvic stability and pelvic floor function, often correlated with SIJ stability.

Warning: It is fundamental to perform these exercises carefully, listening to your body. If an exercise causes acute pain or worsens symptoms, stop it immediately and consult your physical therapist. The progression of exercises must be gradual and personalized.

Prevention of Sacral Bone Pain

Prevention plays a crucial role in maintaining the health of the sacrum and surrounding joints, reducing the risk of developing pain or experiencing recurrence. Adopting healthy and conscious lifestyle habits can make a big difference.

1. Maintain Good Posture

• Sitting: Use ergonomic chairs that support the natural curve of the lumbar spine. Keep both feet flat on the floor and knees at hip height or slightly lower. Avoid sitting with a wallet in your back pocket or crossing your legs for long periods, as this can create pelvic asymmetries. Take frequent breaks to stand up and move.
• Standing: Distribute weight equally on both feet. Avoid standing with weight on only one leg for long periods. Maintain a slight physiological lumbar curve.
• Sleep: Sleep on a supportive mattress. If sleeping on your side, place a pillow between your knees to maintain pelvic alignment. If sleeping on your back, a small pillow under your knees can help reduce lumbar tension.

2. Regular and Balanced Physical Exercise

• Core Strengthening: A strong core (deep abdominal and lumbar muscles) is essential for stabilizing the spine and pelvis, reducing stress on the sacrum. Exercises such as plank, bird-dog, and glute bridge are highly recommended.
• Gluteal Strengthening: The gluteal muscles are fundamental for pelvic stability. Exercises such as clamshells, squats, and lunges can help keep them strong.
• Flexibility: Maintain good flexibility of the lower back, hip, and thigh muscles (e.g., piriformis, hamstrings, hip flexors) through regular stretching.
• Aerobic Activity: Walking, swimming, or cycling are low-impact activities that improve circulation and general health without excessively stressing the sacrum.

3. Avoid Prolonged Sedentary Behavior

Prolonged inactivity can lead to muscle and joint stiffness. Getting up and moving every 30-60 minutes, even for a few minutes, can prevent tension buildup.

4. Ergonomics at Work and Home

Evaluate and adapt your work and home environment to support good posture. This includes desk height, monitor position, use of ergonomic chairs, and arrangement of frequently used objects.

5. Body Weight Management

Overweight and obesity increase the load on weight-bearing joints, including the sacroiliac joint, contributing to pain and degeneration. Maintaining a healthy weight through a balanced diet and physical exercise is fundamental.

6. Correct Lifting Techniques

When lifting heavy objects, bend your knees and keep your back straight, using the strength of your legs and not your back. Keep the object close to your body. Avoid twisting your torso while lifting.

7. Listen to Your Body

Learn to recognize your body’s warning signs and do not ignore pain. If an activity causes pain, modify or avoid it.

8. Avoid Trauma

Pay attention to prevent falls, especially on slippery or uneven surfaces. Use
