A device is disclosed for performing a quantitative analysis of a patient during exercise against isometric, isokinetic, or isoinertial resistance, in order to construct a detailed musculoskeletal model of a human subject. To use the device, the subject grasps a handle which is attached to a length of cable, wound upon a cable spool. Adjustable braking means attached to the cable spool supplies isometric, isokinetic, or isoinertial resistance against unwinding of the cable in order to simulate selected lifting motions. Sensing devices detect the longitudinal and lateral angles at which the patient is pulling the cable. A torsion spring is attached to the cable spool for rewinding the cable. In the preferred version, force sensors are attached to an upper surface of the platform to detect the manner in which the subject\s weight is distributed between the anterior and posterior regions of the subject\s feet, as well as between the subject\s right and left feet. In an alternative embodiment, one or more cameras can be placed at selected positions relative to the lifting platform in order to monitor different aspects of the patient\s body during lifting activity. A computing station is attached to the sensors available in the particular embodiment being utilized, including the cameras if present, and functions to analyze data received therefrom in order to create a biomedical model representative of the patent for use in evaluation. The computing station can also be adapted to accept input from a goniometer in order to perform analysis of the patient\s lumbar spine.

An apparatus for providing resistance to the exertion of force by a human subject during exercise or physiological testing, comprising: a platform with a longitudinal axis and a lateral axis including two support surfaces spaced apart along the lateral axis, each support surface corresponding to one of the subject\s feet; a length of cable and a handle attached to an end of the cable; a cable assembly to dispense and rewind the cable for the subject to pull while the subject is feet are on the respective support surfaces; a brake operatively engaged with said cable assembly for providing a controllable variable resistance to the subject\s pull on the cable; force sensors to provide signals representative of the force exerted by the toe region, heel region, inner region, and outer region of each of the subject\s feed upon its respective support surface; and a first angle sensor for providing output from which a lateral angle of the cable with respect to the platform may be determined.
