Tattoos can cause motor control issues

Tattoos can cause motor control issues

The origin of neck pain and headaches can be mysterious

A new client complained of feeling less stability and strength over the last year. His visits to physiotherapists for a variety of small complaints hadn’t yielded any results. He found me through the www.neurokinetictherapy.com directory. In his interview, he mentioned a lot of neck tension and frequent headaches. The back of his neck was toned up on the right side, but in standing his head position wasn’t significantly altered. However, when we tested his reflexive stability it was most notably lacking in his cervical spine and around his collarbone — the very place he had a very large dark tattoo that encircled the whole area.

Tattoos are Scars

It doesn’t happen very often, but tattoos can cause motor control dysfunctions. They are, in fact, scars – though generally ones that don’t go very deep. I first gained an understanding of how tattoos can affect neuromotor function while studying Neurokinetic Therapy. The founder of NKT has posted about the effects of tattoos on social media several times. Practitioners in other disciplines also treat motor dysfunctions caused by tattoos. Read osteopath Daniel Baines’ account of the dysfunction caused by his tattoo here. Very dark tattoos like the one my client has affect motor control more often than lighter ones or ones that aren’t colored. This client had gotten these tattoos just previous to when he had started to notice the decrease in stability and strength. I did some testing to check the coordination of the cervical spine muscles and found it lacking. However, stimulation of the tattoos improved their function.

Underactive muscles will often get toned up, stiff and painful

These tattoos were downregulating his cervical extensors, especially the ones on the right. These muscles on the back of the neck are critical for holding the head up and for performing neck movements. Underactive muscles will often get toned up, stiff and painful. In fact, I have found that they are more often painful than overactive muscles. This client was compensating in various ways to make up for their inability to function properly. The toned-up muscles there were certainly contributing to his frequent headaches.

Motor control requires a variety of stimuli from the nervous system

Motor control is created through a feedback loop in which information is fed from the body to the cerebellum and back again. Sometimes the body needs less information from a certain part of the body to work correctly. For example, less tension in an area around a scar sends less information about tension to the cerebellum. You can read more about that in this blog entry about scars and motor control.

However, often the body needs more information, more stimulation, or just different information. For example, a muscle that isn’t contracting properly might need to activate to send more information, stimulating the mechanoreceptors for stretch. A joint that is improperly positioned might require deep pressure stimulation in a particular direction in surrounding tissues to function optimally. This might be achieved with a deep tissue massage.

There are a lot of different types of mechanoreceptors. Combinations of different stimuli types mean that there is a much larger variety of types of stimulation. For example, shallow vibration and deep vibration.

Mechanoreceptor stimulation


Mechanoreceptor stimulation must be paired with motor control retraining

This particular area wanted light touch stimulation -sensed by hair follicle receptors or Merkel’s disks. Once the area had been lightly stimulated for a minute or so his cervical extensors started responding in a coordinated way again. The lack of these stimuli was downregulating the cervical extensor muscles. In order to retrain the neck to work properly, those muscles have to be consciously activated soon after the stimuli are fed into the system. Basically, this reminds the motor control center of what this information should be used for.

Homework is often a key part of changing stability issues

Sadly the effect didn’t last very long. This doesn’t mean that the retraining will be ineffective, it just means that it will take more work to make it effective. In order to retrain this area, he will have to stimulate the area, again and again, several times a day for probably a few weeks, maybe longer. He will also have to pair the stimulation with the retraining of his cervical extensors. The homework was simple but critical. To retain positive effects on his reflexive stability and increase motor control he will have to stick with it.
