A body limb movement limiter restrains the movement of a person's arm so as to protect the person's shoulder or restrains the movement of a person's lower leg with respect to the upper leg so as to protect the person's knee. The device uses a housing having a reel disposed therein with a tether attached thereto and a shear thickening non-Newtonian fluid disposed within the housing so that the fluid acts on the reel during a payout procedure of the tether. The housing is attached to a strap secured about the torso of the person while the free end of the tether is secured about the person's arm. Alternately, a pair of arms are pivotally secured to each other within a housing having the non-Newtonian fluid therein for limiting movement of one arm with respect to the other.

I claim: 1. A method of limiting the movement of a person's limb comprising the steps of: providing a housing having an opening and a reel rotatably disposed therein and securing the housing to the person; providing a tether having a first end and a second end; attaching the first end of the tether to the reel, winding the tether about the reel, and securing the second end of the tether to the person's limb; and placing a shear thickening non-Newtonian fluid within the housing for acting on the reel whenever the tether pays out from the housing and such that the pay out of the tether from the housing is decelerated. 2. The method as in claim 1 further comprising the steps of: wherein the step of securing the housing to the person comprises providing a first strap and attaching the housing to the first strap; and securing the first strap about the torso of the person. 3. The method as in claim 2 further comprising a closure means for securing the ends of the first strap together. 4. The method as in claim 2 further comprising the steps of providing a second strap and attaching the second end of the tether; and securing the tether to the limb via the second strap. 5. The method as in claim 4 further comprising a closure means for securing the ends of the second strap together. 6. The method as in claim 4 wherein the tether is comprised of a first section removably secured to a second section. 7. The method as in claim 1 wherein the housing is comprised of a first chamber and a second chamber fluidly sealed from the first chamber and such that the reel is disposed within the first chamber and a rotor is disposed within the second chamber such that the rotor is mechanically connected to the reel such that rotation of the reel causes rotation of the rotor and wherein the shear thickening non-Newtonian fluid is disposed within the second chamber.
