Search Engine for Visually Impaired

Saturday, April 4th, 2009

Did you know Google has a special search engine for the visually impaired? This was news to me. Anyway, the benefit it that it attempts to find websites that work the best with screen readers. Here is the link http://labs.google.com/accessible/
This has potential to be a nice resource for the visually impaired, as well as auditory learners.

Now once you get to the pages, clean up the pages but reducing visual distractions such as advertising and images. Paul Hami’s blog suggests trying TidyRead or Readability. I have tried both of these and they both work differently on different sites. You will have to play around to see what one works best for the student or for you.

Hyperbaric Oxygen and Autism

Friday, April 3rd, 2009

BMC Pediatriccs has published an interesting study on hyperbaric treatment for children with autism. According to the authors of this study, this is the first randomized, double blind controlled trial using hyperbaric oxygen in children with autism. The study had 62 children with autism ages 2-7 years old. The treatment group consisted of 33 children who received hyperbaric oxygen at 1.3 atmosphere (atm) and 24% oxygen. The control group was 29 children who received slightly pressurized room air and 21% oxygen (room air oxygen rate). Both groups received treatments 2x/day for 60 minutes for 5 days/week over 4 weeks. This totalled 40 sessions. The results indicated significant improvements for the treatment group (1.3 atm with 24% oxygen) compared to the control group in the following areas:

1. Overall functioning, receptive language, social interaction and eye contact on the Physician scored Clinical Global Impression Scale
2. Overall functioning, receptive language and eye contact on the Parent scored Clinical Global Impression Scale
3. Total score, irritability, stereotypy, hyperactivity and speech on the Autism Behavior Checklist (larger differences seen in irritability)
4. Sensory/ cognitive awareness on the Autism Treatment Evaluation Checklist (ATEC).

Additional results indicated that children over the age of 5 and children with lower autism severity exhibited greater improvements from the hyperbaric oxygen treatments. This study did not follow the long term benefits of the treatments.

For pediatric therapists, this information provides updated information on the potential benefits of hyperbaric oxygen for children with autism. The significant improvements in sensory/ cognitive awareness is promising. Although, the ATEC section on sensory/ cognitive awareness is very general. Some of the sensory/ cognitive components listed on the test are: danger awareness, initiation of activity, exploration of environment, curiosity, dressing self, does drawing/ art, plays appropriately and more.

In addition, the health section on the ATEC also includes some sensory items such as sound sensitivities, food habits, hyperactive, decreased pain awareness and more. There was no difference seen on the health section of the ATEC.

To view the full study go to BMC Pediatrics.

Communication Technology for iPhone

Thursday, April 2nd, 2009

Proloquo2Go is a new augmentative communication application for the iPhone or the iTouch. It has picture symbols, text to speech and over 7000 vocabulary words. Currently, it is only $149 (obviously you also need to purchase the iphone or itouch). What a bargain compared to a traditional augmentative communication device. Not only is the price great, it is small, fits in a pocket and cool to carry. Not bad!

Free Hands Free Camera Mouse

Thursday, April 2nd, 2009

Heard about this one on Twitter from @assistivetechguru – www.CameraMouse.org. This is a free download for a mouse that works using only head movements. This is for children who can not use their hands but they do have reliable head active range of motion. For the program to work you do need a standard USB webcam, Windows Vista or Windows XP.

Are Schools Exacerbating ADHD?

Wednesday, April 1st, 2009

Previously, I have discussed how important physical activity is for school children (podcast, articles and blog posts). In my opinion, physical activities are being ignored as a potential reason for decreased test scores and behavioral problems in school districts. When children are made to sit all day long, they will act out, be inattentive and their minds wander. Sedentary lessons ignore kinesthetic learners and students with bodily kinesthetic intelligence (Gardner’s Theory of Multiple Intelligences). This is for typically developing students. Now let’s consider students with ADHD and sensory seekers. It makes it even harder to pay attention and learn while having to sit still most of the day.

It appears as if this situation is only getting more dire than better. The Center on Education Policy as part of No Child Left Behind, reported in February 2008 that schools are shifting to more instructional time on English language arts (ELA) and math. This of course occurs at the expense of other subjects. The report shows that on average, schools have decreased recess time by 28% and physical education time by 35%.

Let’s now take a look at ADHD rates. According to the Centers for Disease Control and Prevention, the rates of ADHD have increased on average 3% per year from 1997-2006. As of 2007, 4.5 million children have been diagnosed as having ADHD. This brings us to the question is decreased physical activity time exacerbating ADHD symptoms? Some recent research helps to support the idea that sitting in school all day is detrimental to overall learning.

Neuroscience reports on a study of 20 children who did treadmill walking followed by cognitive testing. The results indicated that following 20 minutes of treadmill training, the children exhibited improved attention and academic performance. Research has also indicated a relationship between amount of time spent outdoors and improved attention in children with ADHD. To view even more research regarding this topic go to www.YourTherapySource.com/articles and click on the Bulk Up the Brain article.

So what can we do? Let’s join the No Child Left Inside (NCLI) this April. Go to the website to find the details and suggested outdoor activites for students of all ages and subject matter. Spread the word and let’s get all children moving and outdoors!
