Rigid Spine Syndrome: Symptoms & Causes

Introduction Of Rigid Spine Syndrome

Rigid Spine Syndrome (RSS) is a rare neuromuscular disorder caused by stiffness and spinal immobility in the neck and trunk. This condition arises from a muscular and connective tissue disorder, linked to congenital myopathies such as SEPN1-related myopathies.

In childhood, patients with rigid spine syndrome have difficulties in neck flexion, poor posture, and spinal movement. As the disease progresses, respiratory muscles are affected, leading to breathing difficulties. 

Causes Of Rigid Spine Syndrome

Rigid Spine Syndrome results from various conditions, including genetic and related to connective tissue disorders. The primary causes include:

  1. Congenital Myopathies:
  • SEPN1-related myopathy is caused by mutations in the SEPN1 gene. It leads to weakness in axial muscles with spinal rigidity.
  • Multiminicore Disease: This myopathy involves the SEPN1 gene or other genes and causes multiple lesions in muscle fibres, resulting in stiffness and reduced mobility.
  1. Muscular Dystrophies: Many conditions, such as Emery-Dreifuss muscular dystrophy present with spine rigidity, joint issue and cardiac symptoms.
  2. Connective Tissue Disorders:  Connective tissue disorders affecting muscle elasticity and joint issues leads to rigidity of the spine.
  3. Neuromuscular Disorders:

In early life, neurodegenerative diseases weakens muscles, supporting the spine, causing RSS.

  1. Postural and Structural Abnormalities:

In childhood, long-term spinal deformities lead to secondary rigidity over time.

Types Of Rigid Spine Syndrome

In neuromuscular disorders, Rigid Spine Syndrome (RSS) is not a single disease. RSS is divided into different types:

  1. SEPN1-Related Rigid Spine Syndrome:

It’s caused by a mutation in the SEPN1 gene (Selenoprotein N1) with early-onset spinal stiffness, axial muscle weakness, respiratory insufficiency and lesser limb strength. It has autosomal recessive inheritance.

  1. Rigid Spine Syndrome Associated with Multiminicore Disease:

Its related to mutations in RYR1 or SEPN1 genes, with multiple pores in muscle fibres resulting in scoliosis, respiratory problems and a rigid spine with limb weakness and joint issues. 

  1. Rigid Spine in Emery-Dreifuss Muscular Dystrophy (EDMD): It’s caused by mutations in EMD or LMNA genes, with early joint issues, cardiac conduction defects and muscle weakness. It’s X-linked, autosomal dominant or autosomal recessive inheritance.
  2. Congenital Muscular Dystrophies with spinal rigidity: It is related to LMNA-related congenital muscular dystrophy, with muscle weakness, spine rigidity, with respiratory difficulties.
  3. Other Forms in non-genetic or acquired causes: It occurs due to spinal trauma, prolonged immobility and secondary to other neuromuscular disorders.

Symptoms Of Rigid Spine Syndrome

Rigid Spine Syndrome presents with a range of symptoms, affecting the muscles of the spine and other body parts. A few symptoms include:

  1. Spinal Rigidity: 
  • Stiffness in the neck and back, cervical and chest regions.
  • Difficulty bending or turning the neck or trunk.
  • Progressive loss of spinal flexibility.
  1. Axial Muscle Weakness:
  • Weakness on spinal muscles.
  • Poor head control and abnormal posture in children.
  1. Respiratory Difficulties:
  • Shortness of breath during sleep.
  • Frequent respiratory infections, requiring non-invasive ventilation support over time.
  1. Skeletal disorders:
  • Scoliosis
  • Joint stiffness
  • Abnormal gait or walking difficulties.
  1. Fatigue and Exercise Intolerance
  • Rapid tiring during physical activity.
  • Low stamina due to weak postural muscles.
  1. Growth and Development Delays:
  • Delayed motor milestones.
  • Short stature or growth problems in some genetic forms.
  1. Mild Limb Weakness:

The mild weakness in the limbs, based on the present condition.

If left unmanaged, symptoms can worsen over time, respiratory issues can become life-threatening.

General Approach Of Rigid Spine Syndrome (RSS)

The general approach is to reduce symptoms, prevent complications, and improve quality of life. Since there is no cure for RSS, treatment focuses on supportive and symptomatic care.

  1. Medical Management

Genetic Counselling: Important for family planning and understanding inheritance patterns. Regular Monitoring, such as Pulmonary function tests, cardiac evaluations and musculoskeletal assessments, is required.

  1. Respiratory Support

Non-invasive ventilation, used for nighttime breathing difficulties or respiratory muscle weakness. Chest physiotherapy is needed to clear secretions and prevent infections.

Side Effects:

  • Skin irritation from masks.
  • Discomfort from ventilation devices.
  • If poorly managed, respiratory infections spread by secretions.
  1. Physical Therapy:

Focuses on:

  • Maintaining spinal flexibility.
  • Preventing stiffness and scoliosis.
  • Strengthening unaffected muscles.

Side Effects:

  • Overexertion may lead to fatigue or muscle injury.
  • Risk of joint stress
  1. Orthopedic Management
  • Bracing to support posture and control scoliosis.
  • Surgery is needed in severe cases of scoliosis or joint stiffness.

Side Effects:

  • Skin issues from prolonged brace use.
  • Surgical risks, such as infection, may occur.
  1. Nutritional and Psychosocial Support
  • Ensures optimal growth and energy in children.
  • Resolves feeding issues in severe muscular weakness.
  • Psychological support for coping with a chronic condition.
  1. Medications 

No specific drug treatment, but advice to take analgesics and muscle relaxants.

Side Effects: Painkillers for GI upset, drowsiness and muscle relaxants for dizziness, fatigue.

Diet Plan for Rigid Spine Syndrome

There is no specific diet to cure Rigid Spine Syndrome, nutritional support is necessary for maintaining muscle health, preventing fatigue, and supporting overall well-being.

 Diet Plan: 

  1. Breakfast:
  • One boiled egg or scrambled egg.
  • One roti with banana or apple.
  • One cup of milk with a spoonful of flaxseed or chia seeds.
  1. Mid-Morning Snack:
  • A handful of almonds or walnuts.
  • Coconut water or a fruit smoothie.
  1. Lunch:
  • One cup of brown rice or 2 chapatis.
  • Grilled chicken, tofu, or lentils.
  • Cooked vegetables.
  • A small bowl of yogurt.
  1. Afternoon Snack:
  • Vegetable soup or buttermilk.
  • A few whole-grain crackers or roasted chickpeas.
  1. Dinner:
  • Two chapatis or 1 cup of quinoa.
  • Soft-cooked vegetables and dal.
  • Grilled fish or paneer with light salad.
  1. Before Bed:

Warm milk with turmeric or if mass is low, a light protein shake is preferable.

Homoeopathic Approach With Few Remedies

In homeopathy, treatment is individualised, focusing on the totality of symptoms, physical, mental and emotional. 

A few Homeopathic Remedies for Rigid Spine Syndrome are:

  1. Calcarea Phosphorica: This medicine is indicated for poor bone and muscle development, spinal curvature and weakness in children. 
  2. Rhus Toxicodendron: This medicine is chosen for stiffness and pain worsening on first movement, better with continued motion.
  3. Causticum: This medicine is indicated for muscular weakness, paralysis-like symptoms, stiffness and difficulty in movement.
  4. Gelsemium Sempervirens: This medicine is used for general muscle weakness, fatigue, trembling and difficulty in lifting the head.
  5. Silicea: This medicine is indicated for slow growth, spine deformities, weak people and infections.

Frequently Asked Questions (FAQs)Of Rigid Spine Syndrome:

  1. How is Rigid Spine Syndrome diagnosed?

Diagnosis involves:

  • Clinical examination consisting of genetic testing, to detect SEPN1 or other mutations
  • Electromyography
  • Muscle biopsy 
  • Pulmonary function tests
  1. Can Rigid Spine Syndrome be cured?

No, there is currently no cure. But with supportive treatments such as physiotherapy, respiratory and orthopaedic care can help manage symptoms and improve quality of life.

  1. Is Rigid Spine Syndrome life-threatening?

RSS is not usually life-threatening on its own. But severe respiratory muscle involvement leads to breathing difficulties.

  1. What is the role of physical therapy?

Physical therapy helps maintain flexibility, prevent joint stiffness and support posture. It is a key part of managing RSS.

  1. Are there dietary recommendations for RSS?

Yes. A high-protein, balanced diet rich in calcium, vitamin D, and omega-3 fatty acids supports muscle and bone health.  If chewing/swallowing is affected, soft and pureed food is needed.
