<p>A medical instrument 1200 comprises a force transducer operable to apply a predetermined force at a position selected from an array of predetermined possible positions 1205 as a stimulus to a test area of a body part, such as the feet, of a patient. The instrument comprises a detector operable to detect a location of the test area of the body part with respect to a current position of the force transducer and the array of predetermined possible positions. A translation element moves the force transducer to one or more positions in the array closest to the location of the test area as detected by the detector. The instrument includes a sample surface 1201 against which the body part of the patient may be placed; the sample surface comprising the array of predetermined possible positions 1205. The detector is operable to detect regions of the sample surface which correspond to a position of the body part with respect to the sample surface. The detector is operable to detect regions of the sample surface which are in physical contact with the body part and to generate a pressure map indicative of pressure at those regions of the sample surface which are detected as being in physical contact with the body part. The instrument is preferably used to apply stimulus force to the surface of the feet for diabetic neuropathy testing.</p> |
