Abstract: Methods and systems are described for creating health status surveys using questions automatically derived from codes of the International Classification of Functioning, Disability and Health (ICF), promulgated by the World Health Organization, and then automatically scheduling the surveys to be provided to patients and their clinicians. Results from the surveys can be compared against results from patients with similar medical diagnoses or surgical procedures. Survey results from patients with different medical diagnoses or surgical procedures can also be compared for questions derived from the same ICF code, resulting in greater pools of data from which to extract statistics.

Abstract: System for data input and storage and for correlation of such data against group data contained in a linked database. The data is input via a series of hierarchical menus, which menus may include sub-menus and fields that enable a user to directly input data for storage into the database. Data regarding an individual may be entered into the database directly by the individual using the hierarchical menu system.

Abstract: A recumbent bilateral reciprocal isokinetic leg exerciser wherein first and second reciprocating members are slidingly coupled to a linear track so that they move with linear bilateral reciprocal motion. Both reciprocating members are coupled to associated hydraulic cylinders so that hydraulic fluid is drawn into or forced out of the hydraulic cylinders as the reciprocating members move along the track. A valve assembly is coupled to the hydraulic cylinders for controlling fluid flow into and out of the hydraulic cylinders so that the reciprocating members move isokinetically. The valve assembly may be set for simultaneous movement of the first and second reciprocating members or for movement of one reciprocating member by itself. To ensure accurate measurement of patient effort, a strain gauge assembly is disposed on each reciprocating member for detecting deformation of the reciprocating member along multiple axes.

Abstract: An apparatus for evaluation of a limb of a test subject. The apparatus generally includes a pedal or grip to secure the distal end of the limb to the apparatus and a seat to secure the proximal end of the limb to the apparatus. A motor and transmission assembly is coupled to the pedal or grip to provide a controlled load to the distal end of the limb. The apparatus also includes a measurement and control system to determine the load to be applied, and to measure and compute the force on each joint of the limb while the controlled load is applied to the limb.

Abstract: A method for diagnosis and/or training of proprioceptor feedback capabilities of a muscle and joint system of a human patient using an exercise system having a patient attachment device and an arrangement for controlling parameters of an exercise movement in response to a control signal derived from one or more measured exercise parameters. A patient performance goal is defined as a real time function of preselected exercise parameters. A perturbation signal function is defined for the control signal; and the control signal is modified by the perturbation function value during a patient exercise motion. The defined performance goal is displayed during the patient exercise motion and the actual patient performance relative to the performance goal is also tracked and displayed. An error value is measured as the difference between actual patient performance and the patient performance goal.

Abstract: A muscle exercise and diagnostic system which includes a lever arm, a mounting arrangement for mounting the lever arm for rotation about a fixed axis, and a connecting arrangement for connecting a selected portion of the human body to the lever arm for rotation with the lever arm about a selected anatomical axis of rotation. The connecting arrangement establishes a fixed tangential mounting relation and a sliding radial mounting relation between the lever arm and the body portion. This permits free radial movement of the connecting arrangement relative to the fixed axis during an exercise motion. A velocity control arrangement is coupled to the lever arm for limiting the maximum permitted rotational velocity to a value predetermined in accordance with a preselected velocity control function which includes measured values of the distances from the point of attachment to the anatomical axis and to the fixed axis. An arrangement is provided for inputting these measured values to a velocity control arrangement.

Abstract: A muscle exercise and diagnostic system which includes a lever arm, a mounting arrangement for mounting the lever arm for rotation about a fixed axis, and a connecting arrangement for connecting a selected portion of the human body to the lever arm for rotation about a selected anatomical axis of rotation. The connecting arrangement provides a fixed tangential and sliding mounting to permit free radial movement of the point of attachment of the patient relative to the axis of rotation of the lever arm. A velocity control arrangement coupled to the lever arm limits the velocity in accordance with a preselected velocity control function. The radial distance from the point of attachment to the axis of rotation is measured and used in the velocity control function. Range of motion limits are set in one embodiment by way of a potentiometer for each limit position and by a pushbutton and limit storing arrangement in another embodiment.
