Many of us have been told that our symptoms are intentional misbehaviour, perhaps being called “lazy” or “attention-seeking.”
It wasn’t explained to us that some of our behaviours are characteristic of neurological differences affecting movement.
I think that understanding “autism” as a sensory-movement disability, rather than as a social disability, might help autistic people to not only better understand ourselves, but to better understand other autistic people.
This makes us better equipped to provide advice to parents and professionals.
Repetitive motor actions e.g., Tapping, touching, grimacing
Rhythmical, cyclical movements e.g., Rocking, shrugging, squinting, pouting
Lack of initiation Requires prompts and cues to perform
Difficulty imitating others’ actions Both immediate and delayed motor imitation difficulties
Echophenomena Mimesis; elaborate copying of others’ actions – verbal and/or motor
Immobility Remains fixed and inert in position and posture for extended time periods
Withdrawal Isolates self away from focal activity and others
Grimacing Facial/oral-motor movements
Stereotypies Repetitive movement of the hands, limbs, extremities, and whole body
Aversion Of eye gaze and attention to others
Negativism Oppositional actions elicited with passive movement and overall behaviour
Automatic obedience; suggestibility Extreme compliance in response to verbal suggestion and environmental cues
Rigidity Muscles rigid to passive movement
BradykinesiaSlowness of movements, feebleness
Tremor Essential, intentional, rest, postural, etc.
Forced grasping Of another’s hands, wrists, etc., or items in the environment
Akinesia Marked absence of action and movements
Akathisia Motor restlessness, moves about but not goal-oriented
Ataxia Loss of coordination in motor action execution
Perseveration Motor or other repeated behaviour after being elicited an initial stimulus
Ambitendency Appears “stuck” in indecisive, hesitant movements
Obstruction; blocking Incomplete movement towards a goal – “gets stuck” en route to goal
Difficulty with stopping, cessation of movement Will continue movements unless redirected or stopped by external means
Mannerisms Uses intact and entire motor action sequences out of context; e.g., salutes
Wavy flexibility Automatic ease and compliance with assuming unusual postures for extended time
Ballismus Violent, rapid, and apparently involuntary actions and movements
Choreiform movements Rapid and apparently involuntary traveling and “dancing” ripples of movement
Catalepsy (posturing) Maintains seemingly uncomfortable and imposed postures for extended time
Atheloid movements Slow, writhing movements and actions
Spasms Muscular spasms of varying durations affecting muscle groups
Dystonias Sustained torsion due to muscle contractions in varied muscle groups
Impulsivity Actions and movements triggered suddenly
Self-injury, mutilation Disturbing and persistent attempts to inflict pain on self
Excitement; frenzy Marked episodes of extreme amounts of activity for extended time
Aggression, destruction Unprecipitated violent actions directed to others and the environment
Stupor Prolonged period of total immobility, lack of responsiveness and mutism
Rituals Object-related actions on objects as part of a routine, repeated event
Motility changes e.g., Toe-walking, skipping, hopping
Changes in speech behaviour e.g., Mutism; question repetition; echolalia; verbigeration; logorrhea; foreign accent; changes in prosody; difficulty modulating volume
Autonomic changes Changes in typical autonomic functions, e.g., heart rate, perspiration, breathing, core body temperature
I think, though, that understanding “autism” as a sensory-movement disability, rather than as a social disability, might help autistic peopl
