Low Back Pain: Causes, Symptoms & Physiotherapy Management

Low back pain (LBP) is pain or discomfort felt in the lower back, between the lower ribs and buttocks. It may develop suddenly or gradually and can range from mild discomfort to severe pain that limits movement and daily activities.

Introduction

Low back pain may be acute, subacute, or chronic, depending on its duration. Physiotherapy can help improve mobility, physical function, strength, and confidence with movement.

Types of Low Back Pain

Low back pain can be classified according to its duration and underlying cause:

  • Acute low back pain: Usually lasts less than 6 weeks.
  • Subacute low back pain: Lasts approximately 6–12 weeks.
  • Chronic low back pain: Persists for more than 12 weeks.
  • Specific low back pain: Associated with an identifiable underlying condition.
  • Non-specific low back pain: No specific structural cause can be identified despite appropriate assessment.

Common Causes

  • Muscle or ligament strain
  • Repetitive lifting or bending
  • Prolonged sitting or inactivity
  • Reduced physical fitness
  • Disc-related problems
  • Facet joint disorders
  • Irritation or compression of spinal nerves
  • Previous episodes of back pain
  • Age-related changes in the spine

In many people, the exact source of low back pain cannot be identified.

Risk Factors

  • Sedentary lifestyle
  • Poor physical conditioning
  • Previous back problems
  • Physically demanding work
  • Repetitive lifting
  • Smoking
  • Excess body weight
  • Psychological and occupational factors

Signs and Symptoms

  • Pain or aching in the lower back
  • Back stiffness
  • Muscle tightness
  • Difficulty bending or lifting
  • Pain aggravated by prolonged sitting or standing
  • Pain extending into the buttock or leg
  • Tingling, numbness, or weakness when nerve involvement is present

Symptoms vary from person to person and should be assessed according to the individual's presentation.

Physiotherapy Assessment

A physiotherapist may assess:

  • History and behavior of symptoms
  • Lumbar movement
  • Muscle strength
  • Flexibility and mobility
  • Posture and movement patterns
  • Functional activities
  • Balance and gait when required
  • Neurological signs when indicated

Imaging such as X-ray or MRI is not routinely required for uncomplicated low back pain and is generally considered when clinically indicated.

Physiotherapy Management

The treatment approach depends on the patient's symptoms, functional limitations, goals, and clinical findings.

1. Patient Education

Patients can be educated about their condition, activity modification, recovery, and ways to gradually return to normal activities. For most uncomplicated low back pain, remaining appropriately active is preferable to prolonged bed rest.

2. Therapeutic Exercise

Exercise is an important component of rehabilitation. Depending on the patient's needs, it may include:

  • Trunk and core strengthening
  • Hip strengthening
  • Mobility exercises
  • Stretching
  • Progressive resistance training
  • Aerobic exercise
  • Functional exercises

Exercises should be progressed gradually according to tolerance and goals.

3. Manual Therapy

When appropriate, manual therapy such as joint mobilization or soft-tissue techniques may be used as part of a broader rehabilitation program. Manual therapy should complement active exercise and self-management rather than replace them.

4. Functional Rehabilitation

Patients can gradually work toward activities such as walking, lifting, household activities, work-related tasks, and recreational activities. A graded return can help restore physical capacity and confidence.

Red flags: Urgent medical assessment is important for new loss of bladder or bowel control, numbness around the groin or saddle area, progressive or severe weakness in the legs, severe pain following significant trauma, fever or significant systemic illness, unexplained weight loss, or a history of cancer accompanied by new concerning back symptoms. These symptoms should not be managed through routine exercise alone.

Prevention and Healthy Back Habits

  • Stay physically active
  • Avoid prolonged inactivity
  • Exercise regularly
  • Gradually build strength and endurance
  • Take movement breaks during prolonged sitting
  • Use sensible lifting techniques
  • Maintain a healthy body weight
  • Follow an individualized exercise program when needed

There is no single perfect posture that guarantees prevention of low back pain. Regular movement and physical activity are more important than maintaining one rigid posture.

Conclusion

Low back pain is a common condition that can affect mobility, work, and quality of life. Physiotherapy focuses on education, exercise, functional rehabilitation, and gradual return to normal activities. An individualized rehabilitation program can help patients improve physical function, manage symptoms, and return to meaningful activities safely.

Frequently Asked Questions

Can physiotherapy help low back pain?

Yes. Physiotherapy can help improve pain, mobility, strength, physical function, and confidence with movement.

Should I stay in bed when I have back pain?

For most uncomplicated low back pain, prolonged bed rest is not recommended. Appropriate activity is generally encouraged.

What is the best exercise for low back pain?

There is no single best exercise for everyone. Exercise should be selected according to the person's symptoms, abilities, goals, and clinical assessment.

Does every person with low back pain need an MRI?

No. Imaging is not routinely required for uncomplicated low back pain and is usually considered when specific clinical indications are present.

When should I seek medical attention?

Seek urgent medical assessment if you develop symptoms such as new bladder or bowel dysfunction, saddle numbness, progressive leg weakness, or severe pain after significant trauma.
