This is done using a combination of neurodevelopmental motor control exercises, primitive reflex inhibition and sensory integration exercises.
Note:
When these exercises are combined with psychological desensitisation strategies anxiety and overwhelming feelings of “overload” can be significantly diminished.
Blocking out pain, to cope, has a down-side. If you block out pain, you are also likely to block out healthy sensations which the brain needs for monitoring safety in your body. That can be threatening to your brain's safety systems. Anything that the brain thinks might be a threat may cause a 'pain output' (or tingling or some other distress output by the brain). Distress outputs are your brain's alarm system to warn you of the potential threat.
Sensory testing can reveal regions or patches of numbness or loss of sensory sensitivity, rather than too much sensitivity. You may not have noticed this before being tested.
If your brain focuses on pain, it reinforces those pain output pathways. That's why some people choose to block it out. However, if we can train the brain to focus on 'normal' sensations, past the pain, it reinforces healthy sensation pathways instead.
