Understanding Sensory Processing Disorder (SPD)
Sensory Processing Disorder (SPD), conceptualized by A. Jean Ayres, occurs when the central nervous system has difficulty receiving, organizing, and responding to sensory input from the environment and the body.
Children may present with Sensory Modulation Disorder: Sensory Over-Responsivity (avoiding textures, loud noises, movement), Sensory Under-Responsivity (quiet, lethargic, slow to respond), or Sensory Seeking (craving intense spinning, crashing, jumping, and deep pressure). Sensory processing deficits impair motor planning, attention, and postural stability.
Vestibular and Proprioceptive Sensory Integration Protocols
The vestibular system (detecting head movement and gravity) and the proprioceptive system (detecting joint position and muscle force) form the sensory foundation for motor control.
| Sensory System | Therapeutic Activity | Physiological CNS Effect | Clinical Purpose | |
|---|---|---|---|---|
| Linear Vestibular | Suspended hammock or platform swing moved smoothly back and forth. | Calming, organizing; lowers sympathetic autonomic arousal. | Regulates over-aroused, hyperactive, or anxious children. | |
| Rotary Vestibular | Spinning on tire swing or rotational sit-and-spin disc. | Alerting, highly stimulating; activates semicircular canals. | Used with extreme caution; alerts sluggish, under-responsive children. | |
| Proprioceptive Heavy Work | Animal walks (bear walk, crab walk), pushing weighted laundry baskets. | Regulating, stabilizing; fires Golgi tendon organs and muscle spindles. | Provides grounding sensory input that calms over-activity and sharpens body schema. | |
| Tactile Deep Pressure | Therapy ball rolling over body, weighted compression blankets. | Parasympathetic activation; releases calming serotonin. | Reduces tactile defensiveness and eases sleep transitions. |
Designing an Effective Home Sensory Diet
A sensory diet is a carefully scheduled menu of personalized physical activities provided throughout the day to keep a child nervous system in an optimal state of alertness and calm.
- Morning Awakening Routine: Jumping on a mini-trampoline for 5 minutes followed by a firm towel rubdown after bath to provide organizing proprioceptive and tactile input before school.
- School Focus Breaks: Using a flexible dynamic seating cushion (wobble disc) and performing desk chair push-ups to sustain postural engagement during classroom learning.
- After-School Grounding Protocol: Crashing into a crash pad or oversized beanbag, climbing playground climbing frames, or crawling through indoor play tunnels to decompress school sensory overload.
Frequently Asked Questions
What are the red flag warning signs of vestibular sensory overload?
Watch for sudden pupillary dilation, pallor, cold sweating, nausea, sudden drowsiness, or extreme irritability. If seen, immediately stop movement and apply deep proprioceptive pressure.
How does proprioceptive heavy work help children with ADHD?
Heavy resistance work sends strong proprioceptive feedback through the ascending reticular activating system, regulating dopamine and norepinephrine levels to improve focus and impulse control.
Can weighted blankets be used without clinical supervision?
Weighted blankets must never exceed 10 percent of the child body weight plus 1 pound, and must never be used with infants or children unable to remove the blanket independently.
