A gentle way to keep older adults moving—hands, wrists, and mind, together.

★ Adjustable Resistance, including a low-start variant

Most older adults in our Zhuhai pilot could not start a standard resistance ball on their own. So the RunOrb uses adjustable resistance from 290g to 30kg—and a low-start variant that lets a caregiver, CNA, or companion-care visitor assist with the first few rotations, then hand it over.

• One device fits residents across independent, assisted, and nursing care levels.
• Staff spend less time per resident, so group sessions actually scale.

★ Gyroscopic Rhythm Sync (not a dumbbell, not a grip ring)

Inside the ball, a rotor spins at a rhythm the user must sense and synchronize with. Keeping it going takes wrist and finger force and timing—so the hand and brain are working together the whole time.

• Alternating left- and right-hand use encourages bilateral coordination as part of a daily routine.
• Unlike lifting a dumbbell or squeezing a grip ring, the movement has a rhythm the user has to match—this is the part that makes it feel engaging rather than repetitive.

Protocol

• Low-impact, seated or standing
• One-on-one or small group
• Staff-led "3-1-3-1" protocol: 3-min warm-up → 1-min ball → 3-min cool-down → 1-min check → 1-min cool-down

★ Not You Driving the Ball — The Ball Guiding You

Conventional exercise relies on your continuous active effort: stop pushing, the movement stops. The RunOrb is different. Once the inner rotor spins up, its significant rotational inertia keeps it turning on its own. You don't force the ball to keep moving — the ball's stable rhythm gently guides your hand to follow along.

★ Everyone Has a Different Resonance Speed

There is no universal "correct" RPM. Each person's body, resting heart rate, and neural sensitivity are different. Users slowly adjust the ball's speed, fine-tuning until they find their own personal frequency zone — the pace where the rotation rhythm begins to align with their heartbeat and breathing.

When that synchronization happens, something remarkable occurs: the steady pulse travels up through the arm, easing tension, creating a sensation described as "a gentle massage for the brain." Mental chatter fades. The body settles into a calm, relaxed state.

How It Works

• Strong inertia: The high-speed rotor has significant angular momentum. Once stabilized, inertia sustains the rotation — forming a stable, continuous external rhythm that doesn't stop at every tiny hand pause.
• Individual variation: Each person's resonance speed differs. There's no standard setting — users feel their way to their own comfortable rhythm.
• Passive-follow rhythm: Traditional exercise is entirely user-driven. RunOrb's inertia creates a sustained beat that the body follows — making it easier to align breathing and heart rate with an external pulse, achieving neural relaxation.

Who Benefits

This makes RunOrb a low-load, self-paced movement suitable for knowledge workers, chronically stressed individuals, older adults, and people across all ability levels. It doesn't pursue high-intensity exertion — instead, it uses inertia-driven rhythm to help users regulate their physical and mental state.

We continue collecting user data through the REI Vitality Index system to further study individual rhythm patterns and refine this all-ability wellness approach.
