Splint
My therapist measured my fingers and told me what to get. The same size will work with my middle and ring fingers for what i need. It's only been a few days. I'm supposed to wear it for two hours. My issue is that the hand it useless while i'm wearing it. I don't watch two hours of TV. My hand has just started being useful for everything. It's my dominant hand and my other hand isn't nearly as dexterous for really anything despite over two months of being the only really working hand. I'm sure this split will help. My therapist hasn't asked me to to anything i consider useless in hind sight. I'm told i'm a month ahead of schedule for strength. Well, i'm working hard at it because i wanted time off for good behavior from the start. The question isn't do i recommend it. The question is does your therapist recommend it. Mine did.
Thanks DME Direct!
I had flexor tendon surgery in one of my fingers and I now have stiffness in the middle knuckle and can't fully extend the finger. My hand therapist recommended this splint to me and DME Direct was able to get it to me in just two days. It's too early to tell if this will fix the stiffness problem but it fits very well and I'm hoping it will help. Thanks very much for having this product in stock and getting it to me so quickly!
Bought a second spring finger extension assist
This is my second time purchasing the finger spring extension assist. DeRoyal referred me to you.
Very pleased with product.
I suffer from Dupuytrens Contracture. I had surgery to correct contracture in my little finger of my left had. The spring finger extension assist has been very helpful in my post-surgery recovery phase.
Excellent product
My wife was unable to keep her right ring finger straight due to a stroke. With this device it has kept it straight; very comfortable to wear. Would highly recommend this device for people with the same issues.
Great price
Great price here which was cheaper than what I found at Amazon.
