The Fitbit is an always-on electronic pedometer, that in addition to counting steps also displays distance traveled, altitude climbed (via a number of flights of steps count), calories burned, current intensity, and time of day. Worn in an armband at night, it also purports to measure the length and quality of a user's sleep.
Another challenge is differentiating walking from running, and recognizing movements like bicycling, climbing stairs, or riding an elevator. Before phone-based systems existed, many custom PDR systems existed. While a pedometer can only be used to measure linear distance traveled, PDR systems have an embedded magnetometer for heading ...
The Childhood Autism Rating Scale (CARS) is a behavior rating scale intended to help diagnose autism. CARS was developed by Eric Schopler , Robert J. Reichler , and Barbara Rochen Renner . The scale was designed to help differentiate children with autism from those with other developmental delays, such as intellectual disability .
A 2003 review of epidemiological studies of children found autism rates ranging from 0.03 to 4.84 per 1,000, with the ratio of autism to Asperger syndrome ranging from 1.5:1 to 16:1; [142] combining the geometric mean ratio of 5:1 with a conservative prevalence estimate for autism of 1.3 per 1,000 suggests indirectly that the prevalence of AS ...
The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time.
In reference to difficulty walking or moving. The term has since been adopted into urban slang to generally refer to something or someone as "meaningless" or "without worth", e.g. "He told us a lame excuse for why he had not done the work."

The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
There are many causes of disability that often affect basic activities of daily living, such as eating, dressing, transferring, and maintaining personal hygiene; or advanced activities of daily living such as shopping, food preparation, driving, or working. However, causes of disability are usually determined by a person's capability to perform ...
