Yes, I have always had an awkward pencil grip. The OT said it was a hyperflexed wrist or something of the sort. I turn my hand upward and tend to rub out words that were written above. When I started teaching primary school I had to learn the correct grip, but it is still a conscious effort, and I always fall back in to old habits when I relax. My son rolls his wrist even further than mine and is left handed. He has hyper mobility, but I thought he might be dyspraxic. Unfortunately the free child health service here is useless and dismiss my concerns regularly.
