What would you say differentiates a child with motor skill issues versus a child who has SPD? With my five year old it's really obvious that it's SPD because the Sensory Modulation symptoms are the most prevalant. My two year old though mostly what we see are delays in her gross motor development and motor planning, clumsiness/falling down easily, low muscle tone, that sort of thing. She sometimes complains about bright lights and does not like slides or little kid rides or things that are difficult for her motor skills but she's doesn't have meltdowns or tantrums really nor does she react strongly to sensory things like touch, smells ect.

People with Neuromuscular Disorders are more likely than the average population to have sensory problems.

Additionally, people with SPD don't necessarily have all their senses that get out of control. For example: My taste sense rarely gets overwhelmed and the few things that bother me I can easily avoid or just "suck it up". My other senses it is impossible to just "suck it up" when they are irritating me.

When my senses are overloading me it makes my Ion Channel Disorder (it affects my muscles) also activate and cause me various movement and muscle problems. I fall often. Prior to Irlen Lenses, a change in light caused me to paralyze and then fall.
