What is a chiropractic adjustment?

A chiropractic adjustment, also called a spinal manipulation or chiropractic manipulation, is a hands-on technique in which a chiropractor uses controlled force to move a joint beyond its normal range of motion. The spine is the most common target, though adjustments can be applied to other joints in the body. The goal is to correct misalignment (called subluxation in chiropractic terminology) and restore normal joint mobility that has been restricted by injury, poor posture, or mechanical dysfunction.

The distinctive audible popping or cracking sound that often accompanies an adjustment occurs due to a sudden change in pressure within the joint space. When the joint surfaces are separated quickly, the pressure inside the capsule drops, causing dissolved gases in the synovial fluid to form bubbles that collapse. This acoustic event, called cavitation, is a normal part of the technique and does not indicate injury or damage.

Chiropractors in the Klang Valley rely on adjustment as a core treatment method to address restricted spinal motion, nerve irritation, and musculoskeletal pain. The technique requires specific training to deliver force at the correct angle, velocity, and amplitude. Patients seeking treatment for spinal and back pain often encounter adjustments as part of a broader care plan that may include stretching, strengthening, and ergonomic advice.
