Chiropractic
A chiropractic adjustment (also called spinal manipulation or joint manipulation) is a controlled, specific force applied to a joint — most often in the spine — to improve motion, reduce stiffness, and relieve discomfort. Adjustments may be performed by hand or with instruments and can be combined with soft‑tissue work, stretching, and home exercises for lasting results.
Dr. Domenic Mancini Jr., DC has been in practice for over 33 years and is currently on the chiropractic team at Simpson Advanced Chiropractic and Medical, diagnosing and treating musculoskeletal conditions of the spine and extremities. Dr. Mancini ran his private practice for over 15 years in New Jersey and Tennessee before relocating, and is now in Port Saint Lucie, Florida.
A 1992 Palmer College of Chiropractic graduate, Dr. Mancini is licensed to practice in the States of Tennessee, North Carolina, New Jersey, California, New Mexico and Florida. He trained in spinal decompression and teaches spinal education and health care classes for patients, along with spinal scoliosis screenings at schools and health fairs. He is always available to speak to groups on ergonomics and proper lifting at work, along with treatments for neck, back, knees, shoulders and other spinal disorders. In his spare time, he loves to enjoy entertainment and music, and stay fit and healthy.
Minimally invasive: no surgery or incisions. You may hear a harmless “pop” as gas releases from the joint.

Chiropractic
Your first visit includes a health history, posture and mobility checks, and targeted orthopedic/neurologic screening. Imaging may be recommended if clinically appropriate. We define your goals (pain relief, mobility, posture, activity/life goals) and outline a plan.
Based on findings, your chiropractor selects techniques (manual or instrument‑assisted) and frequency (e.g., a short relief phase followed by stabilization/maintenance). You'll get simple at‑home tips to support progress.
While positioned comfortably on a padded table, your provider applies a precise, brief force to the targeted joint(s). Some techniques use a drop‑table or handheld instrument for a gentler feel.
Many people notice easier movement right away. Mild soreness — similar to a workout — can occur for 24–48 hours. Hydration, light movement, and the suggested exercises typically help.
Immediately to 24 hours

24–48 hours
Possible mild soreness; light mobility and hydration recommended.
1–2 weeks
With a short series of visits and home exercises, improvements in mobility and posture usually build. Ongoing maintenance is optional based on goals and job/sport demands.
Helps reduce back and neck pain, headaches related to the neck, and stiffness — so you can move more freely.
Targeted adjustments plus simple exercises can help counter desk posture and repetitive‑stress patterns.
Restores joint mechanics to support lifting, sitting, driving, training, and recovery.
Results vary by person and condition. Adjustments complement — not replace — medical care, sleep, and good movement habits.
Who It's For
Chiropractic adjustments are safe for most people when performed by a licensed provider with appropriate screening. Rare complications are possible — your clinician will review risks and alternatives.
Always discuss your personal health situation with the provider. We'll tailor techniques (including gentler options) to your needs.

Most adjustments are comfortable; some people feel a quick, pressure‑like sensation. Temporary soreness — like after new exercise — is possible.
It depends on your goals, exam findings, and how your body responds. Some feel relief quickly; others benefit from a short series plus home exercises before transitioning to maintenance.
