Abstract: A method and apparatus for reliably positioning a 3-segment limb, such as a leg or arm for imaging and medical analysis, which can accommodate for the patient's “natural alignment”. The apparatus positions the limb in such a way that the position of the proximal segment is controlled while an known external torque is applied at a known rate to the distal segment. The location of each of the limb's three segments is recorded using either external or internal measurement techniques, and the relative motions between the proximal and intermediate segments are used in the orthopedic evaluation of the proximal joint. Furthermore, the relative motions between the intermediate and distal segments are used in the orthopedic evaluation of the distal joint. By applying a known torque at a known rate, clinicians will be provided with valuable information related to joint range of motion, stability, laxity, and compliance.

Abstract: Balancing equipment that provides a selectively dynamic platform for an individual thereon. The weight and movement of the individual causes the platform to tilt in any direction, thereby attempting to throw off the balance of the individual, causing the individual to work on maintaining balance while on the dynamic platform. The dynamic nature of the platform can be adjusted to correspond to the balancing abilities of individuals. An adjustment mechanism increases or reduces the amount the platform is able to tilt, without requiring the raising or lowering of any component of the platform. An exercise mechanism can also be connected to the platform to further modify the dynamic nature of the platform.

Abstract: An exercise machine utilizes the inherent capabilities of human muscles to exert greater forces during eccentric functions than during concentric functions. The exercise machine comprises a leverage arm pivotally connected to a frame. A force station is at a first distance from the pivotal connection. During a concentric muscle function, a person lifts first weights on the leverage arm. At the end of the concentric muscle function, a spotter applies a small force to the leverage arm at a second distance greater than the first distance from the pivotal connection. The small force produces a magnified load at the force station that the person resists during an eccentric muscle function. The leverage arm may be adjustable relative to the floor. The weight of the leverage arm may be counterbalanced. Various embodiments of the exercise machine utilize the same principles of physics for exercising different muscles.
