A system and a method of objectively assessing the functional status of a subject utilize a functional status scale to extract objective measures that are indicative of the subject's functional status. The objective measures are extracted from center-of-weight (C.O.W.) data gathered from the functional status scale when the subject is standing on the scale. These objective measures can then be used to assess the current functional status of the subject by a health care provider. The functional status scale can be remotely stationed at the subject's home, which eliminates the need for office visits, expensive home nurse visits, telephone interviews or video visits to assess the current functional status of the subject. The functional status scale includes weight sensors that are connected to a C.O.W. computer. The C.O.W. computer is configured to compute x and y coordinates of the C.O.W. from weight signals generated by the weight sensors. These x and y coordinates are then used to extract the objective measures by analysis modules. The objective measures may be statistical measures, frequency domain measures, or other analytical measures that can be utilized for assessment of a subject's functional status. In one configuration, the analysis modules are included in remote computers that can access a heath care provider's patient database, which receives and stores the x and y coordinates from the functional status scale. In an alternative configuration, the analysis modules are included in the functional status scale. |
