Ankylosing spondylitis is a chronic inflammatory condition that primarily affects the spine and the joints connecting the lower spine to the pelvis. While there is no cure for this disease, modern treatment approaches combine medications, physical therapy, and lifestyle adjustments to relieve pain, reduce inflammation, preserve flexibility, and help people maintain their quality of life. Researchers continue to develop new therapies to help patients manage symptoms more effectively and potentially slow disease progression.

How Treatment Approaches Help Manage This Spinal Condition

The main goals of treating ankylosing spondylitis focus on relieving pain and stiffness while helping people maintain their ability to move comfortably through daily activities. Because this condition causes inflammation in the spine and sacroiliac joints, treatment aims to control this inflammation before it leads to permanent changes in the spine’s structure. When inflammation continues unchecked for years, new bone can form between the vertebrae, gradually fusing sections of the spine together and limiting flexibility.^[1]

Treatment success depends heavily on when it begins. Starting therapy early, before significant joint damage occurs, gives patients the best chance of maintaining mobility and preventing complications. The approach varies based on how active the disease is at any given time. Healthcare providers measure disease activity by combining patient reports of back pain, morning stiffness, and overall health with blood tests that detect inflammation markers like C-reactive protein.^[13]

Most people with ankylosing spondylitis need a combination of treatments rather than relying on medication alone. This comprehensive strategy includes drugs to control inflammation, regular exercise to maintain flexibility and strength, physical therapy to preserve posture and range of motion, and sometimes adjustments to daily routines. The treatment plan evolves over time based on how well symptoms are controlled and whether the condition progresses.^[8]

Medical societies and rheumatologists have established treatment guidelines that help doctors decide which therapies to recommend at different stages. These guidelines emphasize that exercise and physical activity are not optional extras but essential components of treatment, just as important as medication. For many patients, the ultimate goal is achieving remission, which means having no signs or symptoms of active disease, or at minimum reaching very low disease activity where symptoms barely interfere with daily life.^[13]

Standard Medications and Therapies

The foundation of medication treatment for ankylosing spondylitis typically begins with nonsteroidal anti-inflammatory drugs, commonly known as NSAIDs. These medications include familiar names like ibuprofen (sold as Advil or Motrin) and naproxen sodium (sold as Aleve). NSAIDs work by blocking chemicals in the body that cause inflammation and pain. What makes them particularly valuable for this condition is that they may not only relieve symptoms but could actually slow disease progression by reducing the inflammation that leads to bone formation in the spine.^[8]

Doctors often prescribe NSAIDs as continuous daily therapy rather than just taking them when pain occurs. Some patients need higher doses than the amounts available in over-the-counter versions to adequately control their symptoms. The choice of which NSAID to use depends on individual response, since different people respond better to different medications in this class. Healthcare providers monitor patients taking NSAIDs regularly because these drugs can cause side effects, particularly affecting the stomach and intestines. Long-term use sometimes leads to stomach irritation, heartburn, or more serious complications like ulcers.^[11]

When NSAIDs alone don’t provide sufficient relief, or when patients have high disease activity with persistent inflammation, doctors may prescribe more powerful medications. Tumor necrosis factor blockers, also called TNF inhibitors or anti-TNF medicines, represent a major advancement in treating ankylosing spondylitis. These are a type of biologic drug, meaning they’re made from living cells rather than being chemically synthesized. TNF blockers work by targeting tumor necrosis factor, a protein that plays a key role in causing inflammation throughout the body.^[9]

TNF inhibitors are given by injection, either under the skin or through an intravenous infusion depending on which specific medication is prescribed. These medications have proven highly effective at reducing pain and stiffness in many patients who didn’t respond adequately to NSAIDs. Because they suppress part of the immune system, TNF blockers can increase the risk of infections. Doctors screen patients for tuberculosis and other infections before starting these medications and monitor them carefully during treatment.^[11]

Another category of treatment involves monoclonal antibody medications such as secukinumab and ixekizumab. These drugs work differently from TNF blockers by targeting a specific protein called interleukin-17 that contributes to inflammation. Doctors may prescribe these medications for patients who don’t respond well to anti-TNF therapy or as an alternative first-line biologic treatment. They’re also given by injection.^[9]

A newer class of medications called JAK inhibitors offers yet another treatment option. Unlike biologics which are injected, JAK inhibitors come as pills taken by mouth. These drugs work by blocking specific enzymes that the immune system uses to trigger inflammation. JAK inhibitors may be prescribed for people who haven’t responded to TNF blockers or who cannot take injectable medications.^[9]

For patients whose ankylosing spondylitis affects peripheral joints like hips, shoulders, or knees, doctors sometimes add a medication called sulfasalazine. This disease-modifying antirheumatic drug (DMARD) helps reduce inflammation in joints outside the spine, though it’s generally not effective for spinal symptoms. Methotrexate, another DMARD, is occasionally used as well, particularly when peripheral joint involvement is significant.^[11]

The duration of treatment varies considerably. Many patients need to continue medication long-term to maintain symptom control. Doctors assess how well treatments are working at regular intervals, typically checking after three months of therapy with a new medication to determine if it’s providing meaningful benefit. If symptoms don’t improve significantly, the treatment plan may be adjusted by changing doses, switching medications, or adding other therapies.^[9]

Exercise and Physical Therapy as Medical Treatment

Physical therapy and regular exercise are so crucial for managing ankylosing spondylitis that they’re prescribed as medical treatments, not simply recommended as healthy habits. Unlike most other forms of arthritis where rest during flares might help, people with this spinal condition absolutely must keep moving to maintain their mobility and function. Exercise directly counteracts the disease’s tendency to stiffen the spine and limit flexibility.^[9]

A physical therapist creates individualized exercise programs tailored to each patient’s specific needs and limitations. These programs typically include stretching exercises to maintain and improve flexibility, strengthening exercises to support the spine and other affected joints, and aerobic activities to improve overall fitness and endurance. The therapist teaches specific techniques to preserve good posture, which becomes increasingly important as the disease progresses. Posture exercises might include standing against a wall with heels, buttocks, shoulders, and head all touching the wall, practicing this position daily to maintain proper spinal alignment.^[7]

Patients often participate in both group exercise programs with others who have similar conditions and individual home exercise routines. Some physical therapy programs incorporate hydrotherapy, which means exercising in warm water. The buoyancy of water supports body weight, making movement easier and less painful while the warmth helps relax tight muscles. Swimming and water-based exercises are particularly beneficial forms of activity for people with ankylosing spondylitis.^[9]

Low-impact activities that promote flexibility without jarring the spine work best. Many patients find that yoga, Pilates, and tai chi offer excellent combinations of stretching, strengthening, and breathing exercises. These practices emphasize maintaining proper posture and moving through full ranges of motion, exactly what people with this condition need. Walking, cycling, and swimming provide good cardiovascular exercise without putting excessive stress on inflamed joints.^[19]

The timing of exercise matters. Many people with ankylosing spondylitis experience their worst stiffness and pain early in the morning after being still all night. Some find that taking a warm shower or bath before exercising helps loosen stiff joints and makes movement easier. Starting slowly with a gentle warm-up prevents injury and makes the workout more comfortable. Patients should maintain good posture during all activities to reduce strain on the spine.^[17]

Innovative Treatments Being Studied in Clinical Trials

While standard treatments help many people manage their symptoms, researchers continue investigating new therapies that might work even better or help patients who don’t respond adequately to existing options. Clinical trials test these experimental treatments at various stages to determine if they’re safe and effective before they become widely available.

Clinical trials typically progress through three phases. Phase I trials involve small numbers of people and primarily assess safety, figuring out what doses can be given without causing unacceptable side effects. Phase II trials enroll more participants and begin evaluating whether the treatment actually works to reduce symptoms or improve disease measures. Phase III trials are large studies that compare the new treatment directly against standard therapy to determine if it offers advantages over existing options.^[12]

One area of active research involves developing new biologic therapies that target different parts of the inflammatory process. Scientists have identified numerous proteins and immune system pathways involved in causing the inflammation characteristic of ankylosing spondylitis. By creating medications that block specific steps in these pathways, researchers hope to stop inflammation more effectively with fewer side effects than current treatments produce.

Some clinical trials investigate whether existing medications approved for other inflammatory conditions might also help people with ankylosing spondylitis. This research approach can speed up the availability of new treatment options since these drugs have already passed safety testing for other uses. Trials test various dosing schedules, combinations of medications, and strategies for determining which patients will respond best to particular therapies.

Another research direction explores ways to predict disease progression and treatment response. By studying biomarkers in blood or imaging characteristics in MRI scans, scientists work to identify which patients will develop more severe disease and which will respond to specific medications. This personalized medicine approach could eventually allow doctors to select the most effective treatment for each individual from the start, rather than the current trial-and-error process.^[12]

Clinical trials for ankylosing spondylitis take place at research centers around the world, including in the United States, Europe, and other regions. Patients interested in participating typically need to meet specific eligibility criteria related to their disease characteristics, previous treatments, and overall health. Trial participants receive close monitoring and detailed assessments throughout the study period. Some trials provide experimental treatments at no cost, though participants should discuss all potential benefits and risks with their doctors before enrolling.

Advanced imaging techniques are also being refined through research studies. Better imaging could help doctors detect inflammation and structural changes earlier, potentially allowing treatment to begin before permanent damage occurs. Researchers investigate whether more sensitive MRI protocols can identify disease activity that standard X-rays miss, particularly in the early stages when intervention might be most effective.^[12]
