A shimmy damper is used to reduce the back and forth oscillations of the nose wheel at certain speeds.

Explanation:
A shimmy damper is all about controlling lateral motion of the nose wheel. When the aircraft is on the ground, steering inputs, tire-road forces, and inertia can cause the nose wheel to start a back-and-forth vibration known as shimmy. At certain speeds this oscillation can become amplified if not damped, risking steering instability and structural wear. The damper works by resisting sideways wheel movement and dissipating the energy as heat, quickly reducing the amplitude of the oscillation and keeping the nose gear stable. So the statement is true: a shimmy damper is used to reduce nose-wheel oscillations at those speeds.
