"You know those baby exercisers that hang in the doorway - I think they are called Johnny Jump-Ups. They suspend the baby by elastic cords, and the baby can jump and kick without falling. I would think there would be a way to make something like that for an adult invalid, to support her or his body weight while allowing them to move to the music."
So here is my low-cost and low tech stab at a device to help with some mobility support.
Step 1: Materials
- A harness - Depending on their mobility abilities you might want a full body harness. Just about any harness could work. I didn't have my climbing harness but had this arborist harness. I think a harness like the Black Diamond Alpine Bod would work well because of the ease of putting the leg straps on. The nice thing about the harness I used is that it is designed for hanging on the harness for a long period of time. However it is designed for a seated position.
- A large ring - I used a three foot diameter ring from a clothing store rack. You could construct a square or triangle out of lumber but I had this salvaged piece kicking around.
- 6-8 similar diameter inner-tubes from bicycles (these could be old ones with little damage.)
- 3 or more fairly large carabiners, snap links, or threaded connectors
- 20 feet or more of webbing, rope or cable.
- Ceiling attachment rig - perhaps a large eyebolt into a beam, or a length of webbing tied around a beam. Perhaps with a swivel. Or, this could be replaced with a structure attached to casters that would allow for more mobility.
