Chiropractors are trained in using manipulation to free  stiff or restricted joints. This can also be called ‘adjustments’ or ‘manual therapy’. Manipulation involves the chiropractor using their hands to apply quick, precise thrusts to the restricted joints. During manipulation there may be popping sounds (similar to the ‘crack’ heard when  people flex their knuckles). This is quite harmless.  It is just the sound of gas bubbles popping in the fluid of the joints as pressure is released.

Treatment may also include massage, stretching,  and the gradual moving of joints (‘mobilisation’). Some chiropractors use medical  acupuncture techniques, while others may use a hand-held instrument called an ‘activator’ to manipulate joints.
