The present invention provides a device for applying pressure to a wearer of the device, that includes a band adapted for positioning on the wearer, an orb positioned on the band, and a mechanism for selectively varying the length that the orb extends outward from said band. The mechanism includes a dial that is mounted to the orb for user initiated selective rotation about its central axis. By rotating the dial, the orb moves towards or away from the band, thereby decreasing or increasing, respectively, the amount of pressure it will apply to the wearer.
