Low Back Pain

The current (2021) physical therapy treatment guideline is to classify patients into five main categories of low back pain in  order to enhance treatment strategies. These 5 categories reflect the most common ways that low back pain presents itself. 

1. Acute Low Back Pain: Symptoms lasting for 6 weeks or less.

   

2. Chronic Low Back Pain: Symptoms persisting for more than 6 weeks.


3. Low Back Pain with Leg  / Buttock Pain: Referred pain that travels to their buttock, leg, or foot. Pain may or may not be in the low back as well. 


4. Lower Back Pain in Older Adults: 60 years or older who are experiencing low back pain.


5. Postoperative Lower Back Pain: Patients who have undergone surgery for Low back pain. 

Acute Low Back Pain

Physical therapy is an effective treatment for acute low back pain, a common condition affecting many people. It aims to relieve pain, improve mobility, and prevent future episodes. Physical therapists use a combination of exercises, manual therapy, and education to help individuals reduce pain and restore normal movement. Stretching and strengthening exercises focus on the muscles that support the spine, helping to reduce strain and improve stability. Manual therapy techniques, like massage and joint mobilization, can relieve muscle tension and increase flexibility. Additionally, educating patients on proper posture, body mechanics, and lifestyle changes helps them manage pain and prevent future injuries. Overall, physical therapy provides a comprehensive approach to treating acute low back pain, leading to faster recovery and long-term health.

Exercise Training for Acute Low Back Pain

Specific exercises that activate trunk muscles, along with strengthening and endurance exercises for the trunk, are recommended for individuals with acute low back pain (LBP). These exercises focus on building core stability, which supports the spine, reduces strain, and helps prevent future episodes of pain. Exercise programs targeting muscle strength and endurance, as well as specific trunk muscle activation, have shown benefits in reducing pain and disability, particularly for those experiencing related leg pain. 

For example, abdominal bracing is a simple yet effective exercise that involves tightening the abdominal muscles without moving the spine. This exercise can be done while lying on the back with knees bent or even while sitting or standing. It helps activate the deep core muscles that support the spine and improves stability

Another helpful exercise is the bird-dog exercise, which involves kneeling on hands and knees and then extending one arm and the opposite leg while maintaining a neutral spine. This exercise not only targets the core muscles but also helps improve balance and coordination, which are crucial for overall trunk stability.


While exercises like these can be beneficial, current evidence does not point to one specific type of exercise as being superior for treating acute LBP. Therefore, a combination of different exercises that focus on muscle activation, strength, and endurance may be the most effective approach. It is important for individuals to work with a physical therapist to develop a tailored exercise program that meets their specific needs and goals.

Manual and Other Directed Therapies for Acute Low Back Pain

Manual therapies, such as thrust or nonthrust joint mobilization, massage, and soft tissue mobilization, are effective in reducing pain and improving function in patients with acute low back pain (LBP). These hands-on techniques aim to address muscle tension, joint stiffness, and nerve irritation, all of which can contribute to pain and limited mobility.

Thrust or Nonthrust Joint Mobilization: These techniques involve the manual movement of joints to restore their normal range of motion and reduce pain. Thrust mobilization involves a quick, controlled movement applied to a joint to release stiffness, while nonthrust mobilization uses slower, gentler movements to mobilize the joint. Studies have shown that both thrust and nonthrust mobilization can significantly improve disability in patients with acute LBP after 4 weeks and 3 months. For example, a physical therapist may perform lumbar spine mobilization, where the therapist applies pressure to the lower back joints in a rhythmic manner to increase mobility and reduce discomfort.

Soft Tissue Mobilization: This technique focuses on manipulating the soft tissues, such as muscles and fascia, to relieve tension and improve flexibility. Techniques like manual compression at trigger points—where pressure is applied to specific, tight spots within a muscle—have been shown to significantly reduce pain within 1 week and up to 1 month after treatment. Another example of soft tissue mobilization is myofascial release, where the therapist uses their hands to stretch and release tightness in the fascia, the connective tissue surrounding muscles. This can help alleviate pain and restore normal movement patterns.

Physical therapists should consider using thrust or nonthrust joint mobilization as part of the treatment plan to help reduce pain and disability for patients with acute LBP. They may also incorporate massage or soft tissue mobilization techniques for short-term pain relief and to enhance overall function. By combining these manual therapies with other interventions, such as exercise and education, physical therapists can provide a more comprehensive approach to managing acute low back pain.


Classification Systems for Acute Low Back Pain

Different classification systems can guide therapy for acute low back pain (LBP) by helping physical therapists determine the most appropriate treatment approach based on the patient's specific symptoms and physical examination findings. These systems are designed to categorize patients into groups that may benefit from particular interventions, allowing for more targeted and effective treatment.

Mechanical Diagnosis and Therapy (MDT): MDT involves a series of assessments to classify patients into subgroups based on their pain responses to different movements and positions, such as flexion (bending forward), extension (bending backward), or lateral movements (side bending). Once classified, the therapist prescribes exercises and postural corrections that aim to centralize the pain (move it away from the extremities and toward the spine) and reduce overall symptoms. For example, a patient with pain that decreases during repeated lumbar extension exercises (like bending backward) might be categorized in an extension group, and treatment would focus on exercises that encourage lumbar extension.

However, studies have shown that MDT is not necessarily superior to other treatments, such as manual therapy combined with exercise, exercise alone, or education, for reducing pain or disability in patients with acute LBP. For instance, manual therapy combined with specific trunk strengthening exercises has been found to provide similar, if not better, outcomes in some cases, as it addresses both the joint mechanics and the muscle strength needed to support the spine. Similarly, patient education on self-management strategies and the natural course of LBP, combined with simple mobility exercises, can be just as effective in managing symptoms and improving function.


Another example of a classification system is the Treatment-Based Classification (TBC) system, which divides patients into groups based on their symptoms and examination findings:

For example, a patient who benefits from lumbar stabilization exercises, such as abdominal bracing and plank exercises, would be categorized in the stabilization group. The TBC system, like MDT, is designed to provide a structured approach to treating LBP but also faces similar limitations in proving superiority over other standard treatments.

Overall, while classification systems like MDT and TBC can help guide therapy decisions, current evidence suggests that no single system or approach is clearly better than others for all patients with acute LBP. Therefore, physical therapists often use a combination of methods, individualized to the patient's specific needs, to achieve the best outcomes.


Education and Advice for Patients with Acute Low Back Pain

Patient education is a crucial component in managing acute low back pain (LBP) because it empowers patients with knowledge and skills to take an active role in their recovery. Educating patients about the nature of pain, how it can be influenced by psychological and social factors, and effective self-management techniques can help reduce fear, anxiety, and disability associated with LBP. 

Active education strategies involve more than just handing out pamphlets or educational materials; they require engaging one-on-one sessions between the therapist and the patient. These sessions focus on understanding the patient's specific concerns and providing personalized advice on managing pain and staying active. For example, a physical therapist may teach a patient about the biopsychosocial model of pain, explaining how stress, anxiety, or poor sleep can influence pain perception and encouraging strategies to address these factors.

Another key component of active education is teaching self-management techniques. For instance, therapists might instruct patients on the importance of staying active rather than resting excessively, as prolonged inactivity can lead to deconditioning and increased pain. Patients can learn practical skills like pacing activities—breaking tasks into smaller, manageable steps to avoid overexertion—and protecting the back with proper lifting techniques and ergonomics.

Therapists may also provide counseling on the positive outlook for recovery from acute LBP, emphasizing that most episodes of acute LBP are not serious and tend to improve over time with the right approach. This reassurance can help reduce fear and catastrophic thinking, which are common barriers to recovery.


By combining these elements, physical therapists can provide a more comprehensive, interactive, and personalized education plan that not only addresses the physical aspects of LBP but also the psychological and social components, leading to better overall outcomes for patients.

Chronic Low Back Pain

Chronic low back pain is defined as pain persisting for more than six weeks. Unlike acute pain, which is often short-term and directly related to a specific injury or condition, chronic low back pain is more complex and can involve factors such as muscle weakness, poor posture, and altered movement patterns. Managing this type of pain requires a multifaceted approach to address its various underlying causes.

Role of Physical Therapy for Chronic Low Back Pain

Physical therapy is a cornerstone in the management of chronic low back pain, offering a comprehensive approach that includes targeted exercises, manual therapy, and patient education. 


Effectiveness of Different Exercises for Chronic Low Back Pain:

Various exercise types have been studied for their effectiveness in managing chronic low back pain. Each type offers unique benefits, particularly when tailored to the patient’s specific needs and combined with other therapeutic approaches.

Muscle Strengthening and Endurance: These exercises aim to build core stability and support the spine, reducing strain and preventing further injury. For example, planks and bridges are effective in strengthening the abdominal and back muscles. Planks involve holding a position similar to a push-up but with elbows on the ground, which targets the core muscles. Bridges are performed by lying on the back, bending the knees, and lifting the hips off the ground to engage the gluteal and lower back muscles. Studies have shown that combining muscle strengthening exercises with manual therapy, such as spinal manipulation or soft tissue mobilization, provides better outcomes in reducing pain and disability than exercises or manual therapy alone.

Specific Trunk Muscle Activation: This approach is particularly effective for patients with movement control impairments, where specific muscles must be targeted to enhance stability and reduce pain. An example is the abdominal drawing-in maneuver (ADIM), where the patient gently pulls the belly button towards the spine without moving the back or pelvis. This exercise targets the deep trunk muscles, such as the transverse abdominis, which are crucial for spinal stability. Engaging these muscles can help correct movement patterns, reduce pain, and improve function.

Movement Control Exercises: These exercises focus on retraining the body to move correctly, often incorporating balance and flexibility training. For example, the bird-dog exercise involves extending one arm and the opposite leg while keeping the trunk stable. This movement enhances coordination, balance, and strength, and is particularly useful for those with chronic low back pain due to poor movement patterns. Combining these exercises with flexibility exercises, such as hamstring stretches, can help improve pain and reduce disability

Aerobic Exercises: Activities such as walking provide cardiovascular benefits and can help reduce pain levels in some patients. While aerobic exercises like walking, cycling, or swimming can improve overall fitness and promote endorphin release, their effectiveness in reducing pain or disability is not significantly different from other exercise types. Therefore, aerobic exercises are often recommended as part of a comprehensive exercise program.


General and Multimodal Exercises: Combining general exercises with cognitive-behavioral techniques or incorporating multiple exercise types, such as trunk muscle activation, muscle strengthening, and endurance training, can offer holistic benefits. For instance, a program that includes yoga or Pilates might blend stretching, strength training, and mindfulness techniques, promoting both physical and psychological well-being. These multimodal approaches are particularly effective in addressing the multifaceted nature of chronic low back pain.

By incorporating a variety of exercises tailored to individual needs and combining them with other therapeutic techniques, patients with chronic low back pain can achieve significant improvements in pain relief, functionality, and overall quality of life.


Manual and Other Directed Therapies:

Manual therapies, such as mobilization, soft tissue manipulation, massage, neural mobilization, dry needling, and traction, have varying levels of effectiveness:

Education for Patients with Chronic Low Back Pain

Educational interventions, such as group sessions on spine anatomy, proper body mechanics, and pain development, provide moderate benefits in pain reduction. However, combining education with active treatments, such as yoga, Pilates, and strength training, is recommended for more effective management of chronic low back pain.

Low Back Pain with Referred Buttock, leg, or Foot Pain

Low back pain that radiates to the buttock, leg, or foot, often due to nerve involvement such as sciatica, can be effectively managed with targeted physical therapy. The primary goals of therapy are to reduce nerve compression, alleviate pain, and improve function through a combination of specific exercises, manual therapy, and patient education. 


Targeted Exercises:
