1. A limb strength measurement device for measuring strength of a limb under isometric flexion or extension, the limb having a first portion and a second portion pivotable about a joint, the device comprising:

  • a first pair of longitudinal members provided in a spaced relationship, wherein a gap between said first pair of longitudinal members is suitable for insertion of the limb therethrough,a first contact pad supported between said first pair of longitudinal members near a first end thereof;

    a second contact pad supported between said first pair of longitudinal members near a second end thereof;

    a second pair of longitudinal members provided in a spaced relationship, wherein said second pair of longitudinal members are pivotally connected to said first pair of longitudinal members near a first end of said second pair of longitudinal members, and wherein a gap between said second pair of longitudinal members is suitable for insertion of the limb therethrough;

    a third contact pad coupled to said second pair of longitudinal members near a second end thereof,a locking mechanism for locking an angular orientation of said second pair of longitudinal members relative to said first pair of longitudinal members, such that when said device is worn, said first contact pad and said second contact pad contact opposing sides of the first portion of the limb, and said third contact pad contacts the second portion of the limb, thereby securing said device relative to the limb; and

    a force measurement device configured to measure a force applied to said third contact pad by the second portion of the limb.
