Spinal Manipulation (Chiropractic Adjustment) is a hands-on therapy primarily performed by chiropractors to improve spinal function, alleviate pain, and enhance the body's overall ability to heal. 

Purpose:

• Pain Relief: Often used to address back pain, neck pain, and headaches.
• Improved Mobility: Helps restore joint function.
• Nervous System Support: May reduce nerve irritation and improve nerve signaling.

Procedure:

• Assessment: The chiropractor assesses the spine to locate areas of restriction or misalignment.
• Adjustment: Using their hands or a small instrument, they apply a sudden, controlled force to a spinal joint.
• Sound: Often, a popping or cracking sound is heard. This is caused by gas bubbles being released from the joint, similar to cracking knuckles.

Techniques:

• High-Velocity, Low-Amplitude (HVLA): A quick and precise thrust to the joint.
• Mobilization: A gentler, slower movement to stretch and manipulate the joint.
• Drop Table Technique: Uses a special table to assist with adjustments.
• Instrument-Assisted Adjustments: Employs tools like an activator for more precision.
