Truck, stabilization device for exercising/testing hip abduction, adduction, flexion and extension
| Details |
Inventors: Bodine-Reese, Peggy; Reese, John W.;

Primary Examiner: Apley; Richard J.

Attorney, Agent or Firm: Epstein & Edell
A trunk stabilization device permits a standing user/subject to exercise and test hip abduction, adduction, flexion and extension with a conventional muscle exercise and testing machine such as the Cybex II system. A T-bar includes a vertical stem and two adjacent horizontal cross pieces. The stem is secured to the torque transducer unit associated with the machine such that the cross pieces extend horizontally and parallel to the torque axis of the transducer at a location between the transducer and the system support frame. A truck pad, preferably provided as part of the basic machine, is alternatively mountable in two mutually perpendicular and vertical orientations at an end of the cross piece. In one orientation the truck supporting surface is parallel to the torque axis; in the other orientation the axis and trunk supporting surface are mutually perpendicular. In the first orientation, the user, by bracing his/her trunk against the pad, is able to test/exercise hip flexion and extension by pushing/pulling on the transducer actuator with the front of his/her thigh. In the second orientation, the user is able to exercise/test hip abduction/adduction by pushing/pulling with the outside of the thigh in contact with the actuator. |

DETAILED DESCRIPTION It is therefore a primary object of the present invention to provide an apparatus for use with the Cybex II machine to permit testing/exercising of hip abduction, adduction, flexion and extension while the user/subject is standing upright.
It is a more general object of the present invention to provide apparatus for stabilizing a user's trunk to permit testing/exercising of hip abduction, adduction, flexion and extension while the subject is standing upright.
In accordance with the present invention, an adaptor is connected to the torque transducer of the Cybex II system by mounting it on an elongated horizontal bar by which the transducer is positionally secured to the system support frame.
The preferred adaptor takes the form of a T-bar having a vertical stem and a cross piece.
The vertical stem has its lower end secured to the horizontal bar and its upper end secured to the cross piece.
A distal end of the cross piece is capable of being secured to a pad, such as the table extension pad supplied as an accesory with the Cybex II system.
That pad includes a pad support with a first portion extending perpendicularly rearward from the pad and a second portion disposed at right angles to the first portion.
In one orientation of the pad the second portion of the pad support is telescopically engaged in the distal end of the cross piece such that the torque axis of the transducer is parallel to the vertical support surface of the pad.
The user can then brace his/her trunk, back first, against the pad support surface and then test/exercise hip flexion and extension with the front of his/her thigh contacting the transducer actuator.
In a second orientation of the pad, a connector has one part in telescopic engagement with the cross piece of the adaptor and the other part in telescopic engagement with the second portion of the pad support.
In this orientation, the trunk support surface is again vertical but perpendicular to the initial orientation so that the outside of the user's thigh abuts the transducer actuator
