Lower Back Pain: Causes, Symptoms and Physiotherapy Treatment
Lower back pain is one of the most common musculoskeletal problems affecting people of different age groups. It can interfere with walking, sitting, standing, sleeping, working, exercising, and everyday activities.
Lower back pain may develop after lifting something heavy, a sudden movement, prolonged sitting, physical inactivity, sports activity, or an injury. In many cases, the exact cause cannot be identified from a scan alone.
Physiotherapy can play an important role in the management of lower back pain through patient education, appropriate exercise, activity modification, and rehabilitation.
This article explains the common causes and symptoms of lower back pain, the role of physiotherapy, exercises, and situations where medical assessment is important.

What Is Lower Back Pain?
Lower back pain refers to pain, discomfort, or stiffness felt in the lower part of the back, generally around the lumbar region.
The pain may be:
Mild or severe
Occasional or persistent
Localized to the lower back
Associated with stiffness
Increased by certain movements or activities
In some people, pain may also travel from the lower back into the buttock or leg. When leg pain is related to irritation or compression of a spinal nerve root, it may be described as sciatica.
Not every person with lower back pain has sciatica, and the two conditions should not be considered the same.
Common Causes of Lower Back Pain
There are many possible causes and contributing factors. Some common ones include:
1. Muscle or Ligament Strain
Lifting heavy objects, repetitive activities, sudden movements, or an increase in physical activity can sometimes strain muscles or other supporting tissues of the lower back.
2. Prolonged Sitting
People who spend many hours sitting at a desk, driving, or working in the same position may experience back discomfort.
However, posture alone should not be considered the cause of every episode of back pain. Back pain can involve several physical, psychological, occupational, and lifestyle factors.
3. Physical Inactivity
Insufficient physical activity can affect general fitness, strength, and physical capacity. Gradual and appropriate physical activity can be an important part of maintaining function and managing back problems.
4. Disc-Related Problems
Changes or injuries involving the spinal discs can sometimes contribute to lower back pain. In some cases, disc-related problems may also be associated with symptoms extending into the leg.
5. Sports or Occupational Injuries
Sports activities, repetitive work, sudden loading, falls, or accidents may contribute to lower back problems.
6. Age-Related Changes
Structural changes in the spine become more common with age. Importantly, not every change seen on an X-ray or MRI is necessarily the cause of a person's pain.
7. Other Medical Conditions
Less commonly, lower back pain can be associated with conditions such as fracture, infection, inflammatory disease, or cancer.
This is why a proper clinical assessment is important, particularly when symptoms are new, severe, unusual, or changing.
Symptoms of Lower Back Pain
People with lower back pain may experience:
Pain or discomfort in the lower back
Back stiffness
Difficulty bending or changing position
Pain during certain activities
Difficulty sitting or standing for prolonged periods
Reduced ability to perform daily activities
Pain extending toward the buttock or leg
Some people may also experience tingling, numbness, or weakness in the leg.
Neurological symptoms should be assessed by an appropriate healthcare professional.
How Is Lower Back Pain Assessed?
A physiotherapist or doctor may begin by taking a detailed history and performing a physical assessment.
The assessment may consider:
When the pain started
How the symptoms developed
Activities that increase or decrease symptoms
Previous injuries
Work and lifestyle factors
Physical activity levels
Movement limitations
Neurological symptoms
Relevant medical history
A scan is not automatically required for every person with lower back pain.
According to NICE guidance, routine imaging is not recommended for uncomplicated low back pain or sciatica in a non-specialist setting. Imaging may be considered in specialist settings when the result is likely to change management.
Role of Physiotherapy in Lower Back Pain
Physiotherapy can help people understand and manage lower back pain while improving movement and physical function.
The treatment plan should be individualized according to the person's symptoms, examination findings, functional limitations, goals, and overall health.
1. Patient Education
Understanding your condition can help reduce unnecessary fear and improve confidence with movement.
A physiotherapist may explain:
What may be contributing to your symptoms
How to remain active safely
How to modify activities temporarily
How to gradually return to normal activities
How to manage future episodes
2. Exercise Therapy
Exercise-based rehabilitation is an important component of physiotherapy for many people with lower back pain.
Exercises may focus on:
Mobility
Strength
Trunk control
Hip strength
Flexibility where appropriate
Functional activities
General physical fitness
There is no single exercise that is suitable for everyone.
NICE recommends considering an exercise programme tailored to the person's needs, preferences, and capabilities.
3. Strengthening Exercises
Depending on the assessment, strengthening exercises for the trunk, hips, and lower limbs may be included in a rehabilitation programme.
The goal is not simply to "strengthen the back", but to improve overall physical capacity and the person's ability to perform meaningful daily activities.
4. Mobility and Flexibility Exercises
Appropriate mobility exercises may be useful when movement limitations are contributing to functional difficulties.
The type and amount of mobility work should be individualized.
5. Activity Modification
Complete bed rest is generally not the goal of rehabilitation for uncomplicated low back pain.
Where appropriate, people are encouraged to remain active and gradually return to normal activities.
NICE recommends encouraging people with low back pain or sciatica to continue normal activities as much as possible.
6. Manual Therapy
Manual therapy, such as mobilisation or soft-tissue techniques, may be considered for some patients.
However, manual therapy should generally be used as part of a broader treatment programme that includes exercise and other appropriate interventions rather than being relied upon as the only treatment.
Exercises for Lower Back Pain
The most appropriate exercises depend on the individual's condition.
Some exercise categories that may be included in physiotherapy rehabilitation are:
Pelvic Movement Exercises
Gentle pelvic movements may be used to improve movement awareness and spinal mobility in appropriate patients.
Knee-to-Chest Exercises
Certain individuals may benefit from gentle movements involving the hip and lower back.
Core and Trunk Exercises
Appropriate trunk exercises can be incorporated into a progressive rehabilitation programme.
Hip Strengthening
Hip strengthening may be useful when reduced strength or physical capacity is contributing to functional limitations.
Walking
For many people, walking is a simple way to remain physically active. The duration and intensity should be increased gradually according to individual tolerance.
Important: No exercise should be considered universally suitable for every person with back pain. If an exercise causes significant worsening of symptoms, new weakness, increasing numbness, or other concerning symptoms, stop and seek professional advice.
Should You Take Complete Bed Rest for Lower Back Pain?
For uncomplicated lower back pain, prolonged bed rest is generally not the goal.
Maintaining appropriate levels of normal activity and gradually returning to everyday activities can be part of recovery.
However, people with severe symptoms, significant trauma, neurological problems, or other warning signs require individual medical assessment.
Is MRI Necessary for Every Case of Lower Back Pain?
No.
An MRI is not automatically required for every person with lower back pain.
Clinical history and physical assessment are important when deciding whether imaging is appropriate.
NICE recommends against routine imaging in non-specialist settings for uncomplicated low back pain or sciatica. Imaging may be considered when there is a clinical reason and when the result is likely to influence management.
A scan should therefore be interpreted together with the person's symptoms and clinical findings rather than being considered in isolation.
When Should You See a Physiotherapist?
Consider consulting a qualified physiotherapist if:
Your back pain keeps returning
Pain is interfering with daily activities
You have difficulty moving normally
You are having difficulty returning to work or sports
Pain has persisted and is affecting your quality of life
You are unsure which exercises are appropriate for you
You want guidance on safe progression of activity
A physiotherapist can assess your condition and develop an individualized rehabilitation programme when appropriate.
When Should You Seek Urgent Medical Attention?
Most episodes of lower back pain are not caused by a serious disease. However, certain symptoms require prompt medical assessment.
Seek urgent medical attention if back pain is associated with symptoms such as:
New loss of bladder or bowel control
Numbness around the genital, buttock, or saddle area
Significant or rapidly worsening weakness in the legs
Severe symptoms following a major accident or trauma
Severe or rapidly worsening neurological symptoms
Fever or other significant systemic symptoms together with back pain
These symptoms can sometimes indicate a condition requiring urgent evaluation.
Frequently Asked Questions About Lower Back Pain
1. Can physiotherapy help lower back pain?
Physiotherapy can help many people manage lower back pain and improve movement and function. The appropriate treatment depends on the underlying factors, symptoms, duration, and individual goals.
2. Which exercise is best for lower back pain?
There is no single "best" exercise for everyone. A suitable exercise programme should be based on the person's symptoms, physical capacity, assessment findings, and goals.
3. Can I walk if I have lower back pain?
Many people can continue walking at a comfortable level. Gradually increasing activity may help maintain physical function. However, significant worsening of symptoms or neurological symptoms should be assessed by a healthcare professional.
4. Can prolonged sitting cause lower back pain?
Prolonged sitting may contribute to discomfort in some people. Taking regular movement breaks and varying positions can be helpful.
However, back pain is usually influenced by multiple factors rather than one particular posture or position.
5. Is every lower back pain case sciatica?
No. Sciatica generally involves pain related to a spinal nerve root that travels into the leg. Pain limited to the lower back does not automatically mean sciatica.
6. Can physiotherapy start without an MRI?
In many uncomplicated cases, clinical assessment can guide management without immediate imaging. Routine imaging is not recommended for every person with lower back pain.
7. How long does lower back pain take to improve?
Recovery time varies considerably between individuals. Many acute episodes improve over time, while some people experience persistent or recurrent symptoms.
The recovery process can depend on the cause, duration of symptoms, physical activity, general health, work demands, and other individual factors.
Conclusion
Lower back pain is a common condition that can affect people of different ages and activity levels.
Although many cases improve with appropriate self-management and continued activity, persistent, recurrent, severe, or unusual symptoms should be professionally assessed.
Physiotherapy may form an important part of management through education, appropriate exercise, activity modification, movement rehabilitation, and gradual return to normal function.
The goal of physiotherapy is not simply to reduce pain but also to help the individual regain confidence, movement, physical capacity, and participation in everyday activities.
If your lower back pain is affecting your work, sleep, exercise, or daily life, consider consulting a qualified physiotherapist or appropriate healthcare professional for an individual assessment.
