Common classroom modifications for sensory modulation disorder (SMD): Rationale and effect on adaptive response

Rationale and effect on adaptive response

Strategy Rationale Benefit and effect on adaptive response
Dynamic cushion Wedge-shaped: allows child-generated minor movement in linear front to back plane (some bounce) Increases proprioception and thus arousal; suits degree of movement to child; enhances attention; extends work endurance; outlet for sensory-seeking behavior; use on floor to delineate child's space, increasing comfort in group(placing child at periphery can be more tolerable to overresponsive child); increases intensity of sensation
Disc-shaped: allows child-generated variable movement in all planes; heavy work to postural core; can be used on chair or floor
Rocking chair; glider Child-generated, rhythmic, linear movement Child adjusts movement intensity to calm or alert; enhances attention; extends work endurance during quiet times(silent reading); delineates space; provides respite when child needs a break
Cube chair; booster seat; armchair Provides tactile boundaries around child's body Provides constant, predictable pressure touch for calming(especially if padded); delineates space on floor; increases duration of sensation
Small inner tube “Cradles”child when seated on floor Provides constant, predictable pressure touch for calming; child-generated movement as tolerated; delineates space on floor; provides respite
Therapy ball Can be used as alternative to desk chair; provides child-generated movement in multiple planes; can be used for universal support to whole class.Variations for floor: inflated“animal seat,”inflated stool,bolster,peanut-shaped ball Rock for calming; bounce for alerting; extends work endurance and attention to task; outlet for sensory-seeking behavior; adjusts intensity frequency,duration

Environmental Modifications

Strategy Rationale Benefit and effect on adaptive response
Modify walls Limit decorations and/or hangings to include at least one“neutral”wall; paint with calming colors(blues and/or greens) Calms visual environment;removes distraction;enhances attention;prevents gradual escalation of arousal
Modify lighting Turn fluorescent lights down on sunny day;include lamplight;use“daylight”bulbs or full spectrum lighting Reduces harsh light;calms visual environment;enhances attention;may increase work duration;prevents gradual escalation of arousal;flashing lights may be intolerable to overresponsive child
Modify sound Provide background music to suit needs of student;provide movement break;provide rhythm;provide warnings of loud sound(fire drill) Provides calming or alerting auditory sensationCalming:quiet,nature sounds;beat-per-second rhythms;predictable;moderation of teacher voice;“silent clapping”

Wearables

Strategy Rationale Benefit and effect on adaptive response
Weighted vest, shoulder“snake”or lap pad; weighted backpack Increases proprioception and deep pressure touch Calms and/or organizes for self-regulation; increases attention and adaptive response; limits sensory-seeking behavior; weighted back-pack can be worn during transition times between classrooms to organize the overresponsive or sensory-seeking child; regulates intensity, duration
Spandex or Lycra clothing; bike shorts; pressure vests Increases deep pressure touch Calms and/or organizes for self-regulation; regulates intensity, duration
“Body sock”or Lycra wrap Increases deep pressure touch;“heavy”(resistive) work Calms and/or organizes for self-regulation; respite activity; can be incorporated into classroom movement games; social engagement
Hooded sweat-shirt; soft, worn, or all-cotton clothing; seamless socks; tags removed Increases warm and/or tolerable touch; hood allows for occasional“escape” Calms and/or organizes for self-regulation; eliminates sources of nonhabituating tactile sensation that can distract the overresponsive child and escalate behavior
Headphones Provide soothing or alerting sound or no sound; filter or eliminate ambient sound via general noise reduction Calms, alerts, or organizes for self-regulation; provides respite from multiple sound environments of classroom; increases attention to task; may improve test taking; eliminates source of nonhabituating auditory sensation

Routine

Strategy Rationale Benefit and effect on adaptive response
Early arrival or dismissal Enables packing or unpacking before group arrives Reduces likelihood of unwanted physical contact or“chaotic” movement; enables selective attention to arrival and/or dismissal routine; provides a better start and end to the day
Movement breaks Embed regularly into daily routine and learning activities; allow extra as needed Excellent for self-regulation of all children; enhances learning via the movement-learning link
Special assignments Additional movement breaks (bring attendance to office; hand out or collect papers; stack books; erase board; carry materials bin while walking in line; be door holder, note taker, stopwatch manager) Creates embedded proprioception and movement for self-regulation; provides respite; provides outlet for sensory-seeking behavior; provides protection from unwanted sensation; promotes self-esteem and confidence
Daily schedule Predictable or novel, depending on child's needs Predictable for overresponsive child; novelty for underresponsive or sensory-seeking child
Visual schedule Aids predictability of daily events and transitions Reduces anticipatory anxiety and hypervigilance; facilitates work duration when breaks are known

Benefit and effect

Timers Aid predictability of work session or end of break Reduces anticipatory anxiety; facilitates work duration or end of break

Visual timer for child who processes best through visual channel.
