What the evidence says
Spinal manipulation is one of the most studied treatments for low back pain. Clinical guidelines from the American College of Physicians list it among the recommended first-line, non-drug options for acute and chronic low back pain. The typical side effects are mild: soreness, stiffness, or a short headache in a minority of patients, usually gone inside a day or two.
Serious complications are rare. The most discussed risk is a stroke associated with neck manipulation. Large studies have found that people who had a stroke were about as likely to have visited a primary care doctor as a chiropractor in the weeks before, which suggests neck pain from an artery already in trouble sends people to both. That is exactly why the exam matters.
Who should not be adjusted
A careful chiropractor screens every new patient for these before treating. If any of them apply, the treatment changes or you are referred out.
- Fracture, or bone that could fracture: severe osteoporosis, recent trauma with severe pain, cancer that spreads to bone.
- Infection or inflammatory disease of the spine.
- Cauda equina signs: numbness in the groin, loss of bladder or bowel control, rapidly worsening leg weakness.
- Signs of an artery problem in the neck: sudden severe headache, dizziness with vision changes, trouble speaking.
- Blood-thinning medication at high doses, for forceful neck manipulation specifically.
What a safe first visit looks like
You are asked about your history, your medications, and what happened. Your neck and back are examined joint by joint. Your reflexes, strength, and sensation are checked. If anything on that list above shows up, you are not adjusted that day; you are sent for imaging or to a physician. That is what Dr. Frank does on every first visit, and it is the reason a 45-minute first visit exists.
If it is safe, the technique is matched to you. An arthritic or osteoporotic spine gets low-force methods: flexion-distraction, a drop table, mobilization. A fresh whiplash gets gentle work until the ligaments calm down. A healthy 30-year-old with a locked joint gets a manual adjustment. Same office, different tools.
What is not safe
Being adjusted without an exam. Being adjusted by someone who is not a licensed chiropractic physician. Cracking your own neck repeatedly, which loosens the joints that are already loose and never reaches the one that is stuck. And ignoring the warning signs above because an appointment is easier than an ER visit.
