A dedicated protocol

Parkinson's

Specific Logic Workout protocols produce significant improvements in people living with Parkinson's disease, reducing tremors, restoring motor control, and improving quality of life in ways that conventional therapy had not. The results led us to design a dedicated protocol, now available directly in the app.

The protocol is in the app — free for 14 days

Neurological training with the Logic ball

Why it can work

Unpredictability is the stimulus

The Logic ball's rolling, deformation and spring rebound land corrections in the fast 2–12 Hz band, so every repetition asks the nervous system to recruit, brake and redirect in real time. The dedicated protocol dials the load and pace to the person — the stimulus stays reactive, the intensity stays manageable.
