Spinal and limb abnormalities in adolescents with intellectual disabilities.
One in seven teens with ID already shows spinal problems, and extra weight makes it worse.
01Research in Context
What this study did
Lin et al. (2010) checked 822 teens with intellectual disability for spine and limb problems. They used simple exams at special schools. They also weighed each teen and looked at health records.
The team wanted to know how many kids had bent backs, curved spines, or limb limits. They asked if extra weight or past leg injuries raised the risk.
What they found
One in seven teens had a spinal abnormality. One in twelve had a limb abnormality. Higher body weight and earlier leg problems predicted spine trouble.
The study did not test an intervention. It only counted what was already present.
How this fits with other research
Lloyd et al. (2012) and Yuan et al. (2021) show the same age group often carries extra weight. Their data extend this paper’s warning: heavy teens with ID are common, and heavy teens are more likely to have spine issues.
Sawyer et al. (2014) looked at adults over 50 with ID. They found weak bones in nearly half. Together the studies trace a line: skeletal problems start young and keep growing.
Yamaki et al. (2011) link extra weight to added chronic conditions in disabled teens. Their finding supports the BMI–spine link seen here, not a contradiction.
Why it matters
You now have clear numbers to show schools and parents. Add a one-minute spine and leg check when a teen enters special-ed services. Pair it with a height-weight screen. Early flags mean early PT, better seating, and maybe less pain later.

03Original abstract
There are not many studies pertaining to the spinal or limb abnormalities in people with intellectual disabilities, without a clear profile of these deformities of them, efforts to understand its characters and improve their quality of life will be impossible. Therefore, this paper aims to describe the prevalence and related factors of spinal and limb abnormalities in adolescents with intellectual disabilities. The participants who participated in health examinations as they enrolled into special schools at the first year, a total of 822 aged 15-18 years adolescents with ID were recruited to this study. The results showed that there were 14.5% and 8.5% cases had spinal and limb abnormalities based on the physician's observation and X-ray test. Factors of BMI level and limb abnormalities were significantly predicted the spinal abnormality occurrence in those adolescents with ID. Gender, disability level and have a spinal abnormality were variables that can statistically correlate to limb abnormality condition. The study highlights that in order to ensure people with intellectual disabilities receive an appropriate quality of care, it is important to have a precise understanding of the ways in which the needs of them who have spinal or limb deformities differ from the sole intellectual disability and the general population as a whole.
