Chiropractic Glossary: Understand the Terms That Matter

Term

What It Means (For You, the Patient)

Activator Method

A gentle, tool-assisted chiropractic adjustment technique that uses a handheld device to deliver low-force impulses.

Alignment

Refers to how your spine and joints are positioned. Misalignment can lead to pain, inflammation, or nerve issues.

Adjustment

A manual or mechanical technique chiropractors use to restore proper joint alignment and mobility.

Anterior Pelvic Tilt

A common postural imbalance where the pelvis tilts forward, often causing low back pain.

Assessment

Your initial evaluation—includes health history, posture analysis, range of motion, and orthopedic tests.

Atlas

The top vertebra (C1) in your neck, often involved in headaches or neck misalignments.

Axial Load

The force placed along the spine, often tested during postural or injury evaluation.

Back Pain

One of the most common reasons people seek chiropractic care—can involve muscles, joints, discs, or nerves.

Cervical Spine

The top part of your spine (neck region), consisting of seven vertebrae (C1–C7).

Chiropractor (DC)

A licensed healthcare professional trained to diagnose and treat musculoskeletal and nervous system disorders.

Coccyx

Also known as the tailbone—can be adjusted if it’s misaligned or painful.

Compensation Pattern

How your body adjusts movement to avoid pain—can cause further misalignment elsewhere.

Cracking Sound

Also called cavitation—it’s the sound of gas bubbles releasing when a joint is adjusted. It’s normal and painless.

Degenerative Disc Disease

A condition where spinal discs wear down, causing pain, stiffness, or nerve compression.

Disc Bulge

When a spinal disc begins to protrude and possibly press on nerves—may or may not cause pain.

Diversified Technique

A hands-on chiropractic method that uses fast, targeted manual adjustments.

Dynamic Stretching

Movement-based stretches often recommended before exercise or rehab.

Electrotherapy

Modalities like TENS used to reduce pain or inflammation in conjunction with chiropractic care.

Facet Joints

Small joints along your spine that allow for flexibility. Common sources of back or neck pain.

Flexion-Distraction

A chiropractic table-assisted technique used to treat disc herniation and sciatica.

Gait Analysis

Observing your walk to detect biomechanical issues that affect the spine or posture.

Graston Technique

A tool-assisted soft tissue therapy to break up scar tissue and increase mobility.

Herniated Disc

A more severe disc injury where material leaks out and irritates nearby nerves.

Hip Alignment

Evaluated to ensure even leg length and balanced posture—key to spinal health.

HVLA (High-Velocity Low-Amplitude)

A quick, precise thrust used in traditional spinal adjustments.

Ice vs. Heat Therapy

Common at-home advice; ice reduces inflammation, heat loosens tight muscles.

Kinesiological Tape

Elastic tape applied to support muscles, joints, and posture correction.

Laminectomy

A surgical procedure some patients avoid through successful chiropractic care.

A painless treatment that uses light to promote healing in soft tissues.

Lateral Flexion

Side-to-side bending of the spine—often evaluated in mobility tests.

Leg Length Discrepancy

A common postural issue that can lead to pelvic or spinal imbalance.

Lordosis

Natural curve in the lower back—can be exaggerated (hyperlordosis) or diminished (hypolordosis).

Lumbar Spine

The lower back portion of your spine—often treated in cases of posture pain or injury.

MRI

Imaging that may be recommended to view spinal discs, nerves, and soft tissue.

Myofascial Release

A soft tissue technique used to relieve tension in the fascia (connective tissue).

Nerve Compression

When a spinal disc or joint irritates a nerve, causing numbness, tingling, or pain.

Neuroplasticity

Orthotics

Shoe inserts to support posture and spinal alignment, often recommended after assessment.

Range of Motion (ROM)

Measurement of how much a joint or spinal segment can move.

Referral Pain

Pain felt in one area that originates from another—common in spinal issues.

Rehabilitation Plan

The treatment strategy created to restore spinal and muscular function over time.

Repetitive Stress Injury (RSI)

Overuse injuries, such as from sitting or lifting, commonly treated with chiropractic.

Sciatica

Nerve pain that travels down the leg from the lower back—often helped by spinal adjustments.

Scoliosis

A lateral curvature of the spine—mild cases may benefit from chiropractic monitoring and care.

Segmental Dysfunction

Misalignment or lack of motion in a spinal segment that may need correction.
