Forward head posture is one of the most common postural neck misalignments, so you can imagine how hard muscles in the back of the neck have to work to maintain neck posture and alignment.
Misalignments cause certain muscles to be constantly contracted and others to be constantly stretched. This will often more easily contribute to a muscle strain or neck muscle spasm.
This is just an example of forward head posture, let’s imagine a scoliosis posture. With scoliosis we have maybe an “S” shaped curve or a “C” shaped curve when looking at the spine from the front or back. On the one side, muscles will be constantly elongated and tensioned, on the other side they will be shortened and tightened.
These are just two examples, but with any misalignments or abnormal spinal alignments you will affect the muscles.
