Hi
Ds had his OT assessment last week and we've just received the report this afternoon.
The thing that's confusing me is that the results seem well, 'spiky' to say the least.
He scored:
25th Percentile for manual dexterity
5th Percentile for aiming and catching
37th Percentile for balance
Which places him on the 16th Percentile overall.
He was also found to have significant hypotonia, particularly bad with regards to his core/trunk strength.
Some of it makes sense. I can see that as he enjoys lego, has recently learned to touch type (lots of practising) and loves his Nintendo DSi his fine motor skills are exercised regularly and have improved as a result. We bought him a wobble board at the end of the Summer Term 2010 and he spent a lot of time on it over the summer, setting himself targets (its electronic and beginner level though so not that challenging). So I can see how he could have improved to some degree there as well, since he was referred for assessment 12 months ago.
I have seen several papers on the net that say that the 16th centile of the M ABC-2 test should be considered borderline for the amber/at-risk category for dcd, but having spoken to the OT, she says 15 is the upper (therefore borderline) result for the amber category and he would be considered to be at the very bottom of the 'normal for age' group. Which basically means he doesn't qualify for any help.
Now why does that make me suspicious.
On the one hand the report says he isn't able to sit at a desk without slumping and attempting to hold himself up on his arms, yet on the other it says he has good balance. 
I can't quite get my head around how a child with significant hypotonia, particularly in relation to core strength and posture, can have scored so high for balance. (We're talking about a child that never stands when he can sit and never sits when he can lie down here.)
Quote: "was unable to maintain a stable upright posture, due to significanly low muscle tone"
Surely the two things directly contradict each other, as, as I understand it (and I could well be wrong) we use our core strength to hold our position and pull ourselves back into line when we are trying to balance. 
Lastly, he scored very badly for throwing and catching. He particularly struggled with catching a ball that was bounced off the wall and was unable to judge the force and distance of the returning ball, so ended up catching it with his body rather than his hands. He also struggled to judge the distance to a target for throwing beanbags.
Could this be due to poor visual motor co-ordination. We already know he has very poor convergence (despite better than 20/20 vision) and visual motor issues were highlighted as a problem on his WISC IV results. The next assessment he has will be a behavioural optometry assessment, so I suppose we might get some more answers there.
I have just spoken to the OT who did the assessment (who by the way is lovely and very helpful) and asked for one thing that we discussed to be added, but other than that, I am happy with the report in general and particularly the recommendations she's made to the school, as many/most of them back-up recommendations made by the EPs and Inclusion Service.
I do wonder though how much pressure there sometimes is on them to score on the borderline - just above the at-risk category rather than just below. Especially when the letter actually states that they are an oversubscribed service that can't offer support to children that fall outside that group.
I did mention to her that I was surprised at the result, given that he is extremely clumsy and accident prone and struggles with a lot of day to day tasks relating to both fine and gross motor skills but she really didn't answer me on that, other than to say that she was pleased that we are having a visual assessment done and she hoped it would shed more light on his difficulties. 
Not sure what I'm asking here really, other than perhaps am I wrong to be suspicious of his score, when our PCT considers his score to be above the borderline and others would consider him in the lower category?
Also, how unusual is it to get such a huge discrepancy between different sections of the test?
and, does anyone know whether its possible to have extremely poor core strenght but still have good balance?
By the way, I wasn't expecting him to get any support really, so am not surprised that he won't be getting any. I am just trying to get my head around the report and what it means in real terms regarding ds's difficulties.
Any help, advice would be much appreciated.
