Swimming Device

AICP is committed to producing unique devices for our clients in order to help them stay active and engaged. Jerlena Rittwage, a 14 year old girl from Calgary, Alberta, is an example of someone who wanted a device to help them with an activity that their standard devices could not provide assistance for. In this case, the activity was swimming and Jerlena explained that she had to adopt a certain method of swimming in order to compensate for her underdeveloped left hand. The healthcare system does not readily provide specialized devices so we are trying to help bridge the gap between people like Jerlena and their favourite activities.

One way to look at this situation is that the difference in surface area between her left and right hands is causing her right side to overcompensate during swimming, therefore, a device that increases the surface area on her left side would help Jerlena push through the water better, ideally using both arms equally. The device we created was based on this principle. It comprised of a 3D-printed piece that is meant to roughly match the surface area of her right hand, as well as a strap to go around her wrist and some hardware to connect the strap to the 3D-printed part.

The STL file for the printed part is available on our Thingiverse as well as a document containing a bill of materials and assembly instructions. This device was delivered to Jerlena, but was not tested because of covid-19 restrictions that were in place. Once tested, we can use her feedback to work on the next iteration of the device until a near-perfect prototype is designed, which will then be manufactured using reliable methods and materials!
