For OTs, physios, EAs and special-education teachers

You don't have a tools problem. You have a compliance problem.

Putty, grippers and therapy balls get about a week of use, then live in a drawer at the client's house. This is a hands-on challenge people pick up because they want to — so the practice happens between sessions, not just in them.

What your colleagues told us

Your clients don't need another exercise. They need a reason to pick it up.

Adherence is most of the job, and almost nothing on the market is designed for it — it's designed to be correct, not to be wanted.

One object works across a caseload from six to eighty. Twelve holds, thirty-two routes, four difficulty levels.

How it works

  1. Start with one

    Or a 2- or 3-pack for a caseload or a classroom.

  2. Screw on the 12 holds

    One Allen key. Repositionable, so you can set the difficulty yourself.

  3. Set a route, not an exercise

    32 graded routes, Yellow to Purple. They choose; you grade.

  4. Send it home with them

    This is the step the putty never survived.

From professionals who bought one

I am a PT. My hands are my tools.

Post-purchase survey

I will be using it with clients who have arthritic hands, and with a child who I think will enjoy the challenges.

Post-purchase survey

It seems like fun and good for hand motor skills, and I'm an educational assistant. I work with a lot of kids who need a fun way to build their grip and finger strength.
