Autism and T-Rex Arms
Although there is no scientific evidence correlating T-Rex arms with autism, 'T-Rex arms' in autistic people are often observed, although physical characteristics are not typically associated with autism.
However, individuals with autism often exhibit differences in arm movements and motor impairments.
What Is Autism?
Autism, also known as Autism Spectrum Disorder, is a lifelong neurodevelopmental condition affecting the behavior of the affected individual.
We observe autism in a wide range of people regardless of their race, ethnicity, culture, or socioeconomic background, although it is more prevalent in boys than girls [3, 4].
An autistic person perceives the world in a different social and communicative context, resulting in differences in social and communication interactions [3, 4].
Often, people with autism may have difficulties talking to others, maintaining eye contact, and exhibit repetitive patterns of behavior [3, 4]. They often have very niche interests and seem to be in their “own world” [5]. However, the symptoms may vary as it is a spectrum disorder [6].
Autism includes conditions like Asperger syndrome, Rett syndrome, or typical autism [5].
It is believed that autism is strongly influenced by genetics but also environmental factors [7, 8].
What Are T-Rex Arms in Humans?
“T-Rex arms” are often used as a colloquial expression to refer to a condition observed in humans.
Essentially, when someone’s arms are perceived to be shorter than average, creating a disproportion between the limbs and the body, such as the one observed in the dinosaur Tyrannosaurus rex. In addition, the term “T-Rex arms” may also refer to bent arms in the shape of the arms of Tyrannosaurus rex.
Please note that this term does not relate to any evolutionary history of human arms and does not reflect the structure or function of the arms. In contrast, human arms have a greater range of movements and functions than T-Rex arms ever had.
The human arm’s structure and function are complex and encompass extensor and flexor muscles, bones, and assist us in the execution of a variety of actions, such as manipulation of objects or communication among people and animals [1, 2].
In conclusion, while the term "T-Rex arms" is often used in a colloquial context, it does not accurately reflect the complex structure, function, and evolutionary history of human arms.
Do People With Autism Also Suffer From T-Rex Arms?
