Micro Motor control problems may be core issue for people with autism

If you’ve ever had an MRI scan, you know that it can be hard to lie still in the noisy, claustrophobic scanner. People often move involuntarily, requiring scientists to correct or eliminate the imaging data during movement.

Recently, a collaboration of Rutgers University and Columbia University researchers used this seemingly unhelpful data to further their understanding of a neurodevelopmental disease.

“We asked ourselves, ‘What could these involuntary movements, which researchers usually consider a nuisance, tell us about autism?’” Elizabeth Torres, PhD, an associate professor of cognitive psychology at Rutgers, said in a news release.

The neuroscientists analyzed functional magnetic resonance imaging (fMRI) data from 1048 participants, aged 6 to 50 years old, including individuals with autism spectrum disorders and healthy controls. The data was publicly available primarily through the Autism Brain Imaging Data Exchange databases.

The researchers determined that people with autism had more problems controlling their head movements than healthy controls. They also found that motor control problems were exacerbated with the presence of secondary neuropsychiatric diagnoses, lower verbal and performance intelligence and autism severity, as reported in a recent paper in Scientific Reports.

“For the first time, we can demonstrate unambiguously that motor issues are core issues that need to be included in the diagnosis criteria for autism,” Torres said in the release.

In addition, they found that psychotropic medications, commonly used to treat people on the autism spectrum, were associated with lower levels of motor control. These medications include anti-convulsants and anti-depressants. Autistic people who were taking more than one psychotropic medication moved the most during the fMRIs, and their movement worsened over the scanning session.

The researchers conclude in their paper, “Nevertheless, it remains to be demonstrated if changes in head micro-movements directly capture targeted changes in symptomology brought about by a specific medication.” Their findings are also complicated by the simultaneous presence of autism and other diseases, such as attention deficit hyperactivity disorder. So more research is needed.

Top 3 Dental laboratory handpieces and micro motors list

Dental laboratory handpieces and motors are one of the most used equipment in a dental lab; so choosing the best one for your practice should be carefully considered. There is a large number of dental laboratory handpieces and their corresponding motors on the market. Features vary from handpiece to handpiece but can include; all-in-one turbine, air nozzle and spray, reduced weight and ergonomic design, whisper quiet/ no vibration, high torque, fiberoptics and smooth transitioning while increasing or decreasing rpm’s. When choosing a dental laboratory handpiece and motor, consider what features that will be most beneficial to your dental lab as well as what materials your lab works with most frequently.

Most dental laboratory motors come with a corresponding handpiece , however, many vendors also offer a variety handpieces for each motor. Dental laboratory motors are often controlled via foot pedal, although some do offer a hand dial. If space is an issue, there are wall mounted motors. If mobility is important, there are also lightweight compact motors.

Advantages and Disadvantages of Electric Micromotor Dental Units

Electric micromotor dental units are available alone, as slow speed handpieces for polishing and drilling, or combined with an ultrasonic scaler.

How It Works
The electric micromotor dental unit can polish or cut. The handpiece is driven by an electric motor in the handle. The polishing cup, or bur, can variably rotate from 0 to 30,000 rpm and go forward or reverse. It provides a very high torque. The handpiece can take a prophy angle, with polishing cups, or a contra-angle, with various attachments, including RA burs and polishing cups. Only a few units have a water-cooling facility.

Long HP burs can also be used in the nose cone (when the prophy angle is removed). They are used principally for trimming small herbivore cheek teeth.

Advantages
Relatively inexpensive, compared with an air driven unit.
Generally small, compact and mobile.

Disadvantages
Very slow in dental terms therefore extremely limited efficiency.
Burs 'walk off' teeth during cutting, due to slow speed.
Handpieces vibrate and heat up after a few minutes.
The torque is high. This is an advantage when polishing but a severe disadvantage for drilling tissues which will not be removed (e.g. bones).
