Lower back pain and sciatica: the benefits of exercise and movement as treatment modality

Lower back pain (LBP) is a prevalent issue affecting millions worldwide, with non-specific lower back pain (NSLBP) and sciatica significantly impacting individuals' quality of life. Unlike passive treatments, exercise and movement have emerged as cornerstone treatments, promoting active engagement and empowering individuals to manage their conditions effectively.

Lower back pain (LBP) is a prevalent health issue affecting millions worldwide. Non-specific lower back pain (NSLBP), which lacks a clear structural cause, and sciatica, characterised by radiating pain along the sciatic nerve, significantly impact individuals’ quality of life. Exercise and movement have gained recognition as effective treatment modalities for these conditions, supported by extensive research and clinical evidence. This article discusses  the benefits of exercise and movement for NSLBP and sciatica, examining the underlying mechanisms and presenting evidence-based recommendations.

The Prevalence and Impact of NSLBP and Sciatica

NSLBP is one of the leading causes of disability globally, affecting individuals across all age groups. It is characterised by pain, stiffness, and discomfort in the lower back region without a specific identifiable pathology. Sciatica, on the other hand, is typically caused by compression or irritation of the sciatic nerve, resulting in pain that radiates from the lower back to the buttocks and down the leg. Both conditions can lead to significant functional limitations, reduced productivity, and decreased quality of life.

The Role of Exercise and Movement in Treating NSLBP and Sciatica

Exercise and movement have emerged as cornerstone treatments for NSLBP and sciatica. Unlike passive treatments such as bed rest and medications, exercise promotes active engagement and empowers individuals to manage their conditions effectively. The benefits of exercise and movement for these conditions are multifaceted:

  1. Pain Reduction and Management: Regular exercise has been shown to alleviate pain associated with NSLBP and sciatica. It achieves this through various mechanisms, including increased blood flow, improved flexibility, and enhanced muscle strength. Exercise also stimulates the release of endorphins, which are natural pain-relieving chemicals in the body.
  2. Improved Function and Mobility: Engaging in exercise helps restore normal movement patterns and enhances functional abilities. Strengthening the core muscles, improving posture, and increasing flexibility contribute to better spinal alignment and reduced pressure on the sciatic nerve.
  3. Psychological Benefits: Chronic pain conditions like NSLBP and sciatica can lead to anxiety, depression, and a decreased sense of well-being. Exercise has been shown to have positive effects on mental health, reducing symptoms of anxiety and depression and improving overall mood.
  4. Prevention of Recurrence: Regular physical activity helps prevent the recurrence of NSLBP and sciatica. By maintaining a strong and flexible musculoskeletal system, individuals are less likely to experience future episodes of pain.

Evidence-Based Exercise Interventions for NSLBP and Sciatica

Numerous studies have investigated the effectiveness of various exercise interventions for NSLBP and sciatica. The findings consistently support the role of exercise in managing these conditions. Here, we present a summary of key studies and their findings:

  1. Structured Exercise vs. Advice to Stay Active: A systematic review and meta-analysis conducted by Fernandez et al. (2015) compared structured exercise programs to advice to stay active for managing NSLBP. The study concluded that structured exercise provided superior effects in reducing pain and improving function compared to advice alone.

Mechanisms Underlying the Benefits of Exercise

The beneficial effects of exercise on NSLBP and sciatica can be attributed to several physiological and biochemical mechanisms:

  1. Increased Blood Flow: Exercise enhances blood circulation, delivering oxygen and nutrients to the affected tissues and promoting the removal of metabolic waste products. This helps reduce inflammation and accelerates the healing process.
  2. Muscle Strengthening and Flexibility: Strengthening the core muscles, including the abdominal and back muscles, provides better support to the spine and reduces the risk of injury. Improved flexibility in the muscles and ligaments surrounding the spine enhances overall mobility and reduces stiffness.
  3. Endorphin Release: Physical activity stimulates the release of endorphins, which are natural painkillers produced by the body. Endorphins bind to pain receptors in the brain, reducing the perception of pain and promoting a sense of well-being.
  4. Neuroplasticity: Exercise promotes neuroplasticity, the brain’s ability to reorganise and form new neural connections. This adaptation helps modulate pain signalling pathways, reducing the intensity of chronic pain conditions like sciatica.
  5. Psychological Resilience: Engaging in regular exercise fosters a sense of accomplishment and empowerment, reducing the psychological burden of chronic pain. It also provides a distraction from pain and promotes relaxation through activities such as yoga and mindfulness-based exercises.

Recommendations for Exercise and Movement in NSLBP and Sciatica

Based on the evidence, healthcare professionals recommend a multimodal approach to exercise for managing NSLBP and sciatica. Here are some practical recommendations:

  1. Aerobic Exercise: Activities such as walking, swimming, and cycling improve cardiovascular fitness and overall well-being. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
  2. Strength Training: Incorporate exercises that target the core muscles, including the abdominal, back, and pelvic muscles. Examples include planks, bridges, and resistance band exercises. Perform strength training exercises 2-3 times per week.
  3. Flexibility and Stretching: Regular stretching exercises improve flexibility and reduce muscle tension. Focus on stretches for the lower back, hamstrings, and hip flexors. Yoga and Pilates are excellent options for enhancing flexibility and promoting relaxation.
  4. Neural Mobilisation: Neural mobilisation exercises, performed under the guidance of a trained therapist, can help alleviate sciatic pain by reducing nerve tension and improving nerve gliding. These exercises should be performed with caution and under professional supervision.
  5. Gradual Progression: Start with low-impact exercises and gradually increase the intensity and duration. Avoid sudden, high-impact activities that may exacerbate pain. Listen to your body and modify exercises as needed.
  6. Consistency and Persistence: Consistency is key to achieving long-term benefits. Incorporate exercise into your daily routine and make it a habit. Even small amounts of physical activity can have significant positive effects over time.
  7. Professional Guidance: Consult with a healthcare professional, such as a physical therapist or exercise physiologist, to develop a personalised exercise plan tailored to your specific needs and limitations. They can provide guidance on proper form, technique, and progression.
