One-arm-drive self-propelled standing mobility device for pediatric patients with hemiplegia.

Similar projects worth following
We are an undergraduate design team at Johns Hopkins University and we developed this prototype of a standing mobility device which can be propelled, steered, and braked using only one arm. This was created for people with loss of function in one arm and one or both legs, primarily for children with hemiplegia and GMFCS Level IV. We want to share our novel steering mechanism in hopes that it can be implemented into future one-arm-drive self-propelled mobility devices.

I am very interested in this project As I am a hemiplegic and could find this useful. I would like to try it out. Where can I view a video bin how this works?

Hi! I just stumbled upon this project, and I have some personal interest in looking at how it helps patients with partial loss of mobility, especially to stand up/sit down/walk.

Is there a video or some demo that I can view, to understand this in further detail? Any information is highly appreciated.

Either way, I must say that this is a great project that your team has done. You seem to have a genuinely great vision and motive. Hats off to you!

Thank you! If you download the UNIstand project summary ppt, there is a detailed explanation of our steering mechanism as well as some video of us using the device.

Outstanding work. I am going to point this out to a contact in the mobility department at Nemours Hospital for Children over in Delaware.
