We often think of the five basic senses — vision, hearing, touch, taste, and smell. But there are two lesser-known senses that are just as important: proprioception (awareness of body position) and the vestibular sense (balance and spatial orientation). Together, these seven senses guide everything from tying shoelaces to exploring the world around us.
For most people, the brain processes these sensory inputs seamlessly. But for some, the system struggles — creating challenges in interpreting and responding to everyday stimuli. This is known as a Sensory Processing Disorder (SPD).
And contrary to common belief, SPDs don’t affect only children — adults live with them too. The good news? With the right diagnosis and intervention, individuals with SPDs can build resilience, independence, and confidence.
Signs and Symptoms of Sensory Processing Disorders
SPDs can look different for every individual. Some common signs include:
- Strong reactions to ordinary sights, sounds, or textures (hypersensitivity).
- Low or delayed responses to stimuli, including pain or danger (hyposensitivity).
- Cravings for certain sensory experiences, such as spinning, touching, or making noise.
- Difficulty with balance, coordination, or fine motor skills.
- Overwhelm or anxiety in sensory-rich environments such as malls, classrooms, or offices.
Types of Sensory Processing Disorders
- Sensory Modulation Disorder (SMD)
- Overresponsivity (SOR): Heightened sensitivity; discomfort with noises, textures, or lights.
- Underresponsivity (SUR): Reduced sensitivity; failure to notice important cues.
- Sensory Seeking (SS): Craving constant sensory input, often restless or impulsive.
- Sensory-Based Motor Disorder (SBMD)
- Challenges with coordination, balance, and motor planning. Everyday tasks like riding a bike or buttoning a shirt can feel overwhelming.
- Sensory Discrimination Disorder (SDD)
- Difficulty telling stimuli apart (e.g., hot vs. cold, rough vs. smooth, loud vs. soft).
- Sensory-Related Anxiety
- Fear or panic triggered by everyday sensory input, such as crowded places or loud sounds.
Who Needs Sensory Integration Therapy?
Children or adults showing the above signs may benefit from therapy — especially if:
- Their daily activities (eating, dressing, studying, working) are disrupted.
- They avoid or over-seek certain environments.
- They experience frequent meltdowns, restlessness, or social withdrawal.
- They struggle with motor coordination or fine motor tasks.
How Sensory Processing Issues Affect Daily Life
Sensory challenges are not just about comfort — they can impact:
- Learning and attention: Difficulty focusing in classrooms or workplaces.
- Social participation: Avoidance of peers or group activities due to overwhelm.
- Independence: Needing constant support for dressing, eating, or navigating spaces.
- Emotional well-being: Heightened stress, anxiety, or low confidence.
How Therapy is Adapted for Different Age Groups
At Plexus, we recognize that age plays a key role in therapy design:
- Toddlers and preschoolers: Focus on early intervention, play-based sensory activities, and parent coaching.
- School-age children: Structured sensory diets, classroom adaptations, and motor skill training.
- Teenagers: Support for self-regulation, independence, and academic participation.
- Adults: Workplace modifications, stress-management techniques, and occupational therapy to improve day-to-day functioning.
Managing Sensory Processing Disorders
Effective management combines multiple therapies tailored to the individual’s needs:
- Sensory Integration Therapy: Core approach using structured sensory-rich activities.
- Occupational Therapy: Builds motor skills, independence, and coping strategies.
- Behavioral Interventions (CBT/BT): Helps manage sensory-related anxiety.
- Sensory Diets: Personalized daily activities to regulate sensory input.
The goal is not just adaptation but empowerment — enabling individuals to thrive in a sensory-rich world.
FAQ
What is sensory processing therapy?
Sensory processing therapy (or sensory integration therapy) uses structured, sensory-rich activities to help the brain adapt to overwhelming input.
What type of disorder is SPD?
SPDs are neurological conditions that affect how the brain interprets and responds to sensory information.
Can sensory issues be cured? Which type of sensory processing disorder is most common?
SPDs cannot be cured, but they can be managed effectively with therapy. The most common type is Sensory Modulation Disorder.
At what age do sensory processing issues typically appear?
Symptoms usually appear in toddlerhood (ages 1–4), though adults can also live with undiagnosed SPD.
What are the four patterns of sensory processing behavior?
Low registration, sensation seeking, sensory sensitivity, and sensation avoiding.
What are the five main sensory systems in the human body?
Visual, auditory, olfactory (smell), gustatory (taste), and tactile (touch).
