[quote=“dm59”]I’m not sure how old you are but, even though moving the thumb can generate some movement (a good thing), it also has a tendencyt to impart a “slider” spin as a result of the hand rotating (supinating) into release. This happened to my son 4 years ago, when he was 11. His thumb was up at 5:00 , or 7:00, depending on how you look at it. The resulting motion caused a repetitive strain injury on the tendon that attaches to the medial epicondyle (the bony protrusion on the inside of the elbow). After a month of not pitching and physio, I finally noticed what he was doing. After fixing this, he’s had no recurrance of the issue.
I’m not saying don’t do it. Just that you should be aware that this has the potential to cause a slider like motion in the hand and that should be taken into account. At early ages, this should be limited and/or monitored.[/quote]
I’m 11 and sometimes when it comes off of my hand (5/10 times) it creates my wrist to kind of spin. Is this bad, or just part of the thumb moving?
