Chiropractic is a licensed healthcare profession focused on the musculoskeletal system, particularly the spine. Treatment typically involves hands-on manipulation of the joints to restore mobility, reduce pain, and support the body’s ability to heal without medication or surgery. Chiropractors hold a Doctor of Chiropractic (DC) degree, and the profession is regulated and licensed in all 50 U.S. states.
What Chiropractors Actually Do
The core of chiropractic care is the spinal adjustment: a controlled, quick thrust applied to a joint that isn’t moving properly. The goal is to restore normal range of motion, relieve pressure on surrounding nerves, and reduce muscle tension. Most visits last 15 to 30 minutes, and the adjustment itself takes only seconds per joint.
Chiropractors use several techniques depending on the patient and the problem. The most common is a manual hands-on thrust where the chiropractor positions you on your side or face-down and applies a precise, fast push to a specific joint. Another popular method uses a specialized table with sections that drop slightly during the thrust. The dropping segment works with gravity and your body weight so the chiropractor needs less force, making it a gentler option. Some practitioners also use a small handheld instrument that delivers a light, targeted impulse to the joint without any twisting or positioning.
Beyond adjustments, many chiropractors incorporate stretching, soft tissue work, exercise recommendations, and posture correction into their treatment plans.
The Popping Sound, Explained
That cracking or popping noise during an adjustment is not bones grinding together. It comes from gas bubbles forming inside the fluid that lubricates your joints. When the chiropractor applies a quick stretch to the joint capsule, pressure inside the joint drops suddenly, and dissolved carbon dioxide escapes from the fluid into the joint space. The released gas makes up about 15% of the joint’s volume and is roughly 80% carbon dioxide. The sound is similar to what happens when you crack your knuckles. It’s painless for most people, and not every adjustment produces it.
Conditions It Helps Most
Low back pain is the most common reason people visit a chiropractor. The American College of Physicians includes spinal manipulation in its clinical guidelines as a first-line, non-drug treatment for both acute and chronic low back pain. The recommendation is notable because it suggests trying approaches like manipulation, heat, massage, or acupuncture before reaching for medication.
Chiropractic care also has evidence supporting its use for certain types of headaches. Research published in the Journal of Manipulative and Physiological Therapeutics found that spinal manipulation improves migraine and cervicogenic headaches (headaches that originate from neck problems). For tension-type headaches, the evidence is less clear, and manipulation alone may not be enough. Joint mobilization and specific neck-strengthening exercises tend to work better for that type.
People also commonly seek chiropractic treatment for neck pain, sciatica, and joint stiffness. It’s generally considered most effective for mechanical pain, meaning pain caused by how joints and muscles move rather than by infection, tumors, or inflammatory disease.
What Happens at Your First Visit
An initial chiropractic visit looks a lot like any other healthcare intake. You’ll fill out a health questionnaire covering your medical history, current symptoms, and lifestyle. The chiropractor will then perform a physical exam that includes checking your range of motion, testing reflexes, comparing muscle strength on both sides, and palpating (pressing on) the spine to find areas of tenderness or restricted movement.
Even if your complaint is in your lower back, the chiropractor will typically examine your entire spine. Neurological and orthopedic tests focused on your main complaint are standard. X-rays are sometimes ordered but have become much less routine than they used to be. Most chiropractors now reserve imaging for cases where they suspect a fracture, structural abnormality, or other red flag. After the exam, you’ll usually receive your first adjustment the same day, along with a recommended treatment plan that might range from a few visits to several weeks of care.
Training and Credentials
Chiropractors complete a minimum of 4,200 hours of classroom, laboratory, and supervised clinical training to earn their Doctor of Chiropractic degree. The program typically takes four years after completing undergraduate prerequisites in biology, chemistry, and physics. Coursework covers anatomy, physiology, radiology, diagnosis, and hands-on technique. After graduating, chiropractors must pass national board exams and obtain a state license before practicing.
Safety and Who Should Avoid It
Chiropractic adjustment is safe for the large majority of people. The most common side effects are mild soreness or stiffness in the treated area, similar to what you might feel after a workout. These typically fade within 24 hours.
Serious complications are extremely rare. The most discussed risk is a type of stroke caused by injury to arteries in the neck. Estimates put the incidence of stroke following cervical manipulation somewhere between 0.05 and 1.46 per 10 million manipulations. A study of Medicare beneficiaries aged 66 to 99 found that the rate of this type of stroke was too low to even report statistically.
That said, certain conditions make spinal manipulation unsafe. You should not receive a chiropractic adjustment if you have severe osteoporosis, cancer in your spine, numbness or loss of strength in an arm or leg, an increased risk of stroke, or a known structural abnormality in the upper neck. A good chiropractor will screen for these during your initial exam.
Cost and Insurance Coverage
Most private health insurance plans cover chiropractic care to some degree, though the number of visits per year may be capped. Medicare Part B covers manual spinal manipulation to correct a subluxation (a joint that isn’t moving properly but remains intact). After meeting your Part B deductible, you pay 20% of the approved amount. Medicare does not cover other services a chiropractor might offer, including X-rays, massage therapy, or acupuncture.
Without insurance, a single chiropractic visit typically costs between $30 and $200 depending on the region and the complexity of treatment. Many offices offer package pricing or sliding-scale fees for patients paying out of pocket.
