Physiological assessment system and method
First Claim
1. A electrophysiological assessment method of the type useable to assess a physiological condition, the electrophysiological assessment method comprising the steps of:
- (A) collecting at least one electrophysiological signal of an asymptomatic sensory area to obtain asymptomatic response data;
(B) collecting at least one electrophysiological signal of an symptomatic sensory area to obtain symptomatic response data; and
(C) comparing the symptomatic response data to the asymptomatic response data to assess a physiological condition.

Abstract
A system and method for physiological assessment utilizes electrophysiological techniques, such as evoked potential (EP) data. Symptomatic and asymptomatic sensory areas are stimulated and EP data are collected. Artifacts can optionally be deleted from the raw EP data, which can then be appropriately filtered and transformed using software filtering and signal processing transformation techniques. Points of interest are detected and labeled on the resulting traces, which are output for analysis, diagnosis and treatment purposes. Differences between symptomatic and asymptomatic EPs provide objective, quantitative, repeatable information about pathological conditions.

26. A physiological assessment method of the type useable to assess a physiological condition, the physiological assessment method comprising the steps of:
-
(A) measuring at least a first electrophysiological signal of asymptomatic tissue comprising the steps of;
(a) attaching a stimulus unit to an asymptomatic sensory area;
(b) stimulating the asymptomatic sensory area; and
(c) collecting at least one electrophysiological signal of the asymptomatic sensory area to obtain first asymptomatic response data;
(B) measuring at least a first electrophysiological signal of symptomatic tissue comprising the steps of;
(a) attaching a stimulus unit to a symptomatic sensory area;
(b) stimulating the symptomatic sensory area;
(c) waiting for a predetermined time period; and
(d) collecting at least one electrophysiological signal of the symptomatic sensory area to obtain first symptomatic response data. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A method for measuring the attenuation of a somatosensory condition comprising:
-
(A) using an electrophysiological technique to obtain somatosensory asymptomatic response data from an asymptomatic sensory area;
(B) using an electrophysiological technique to obtain somatosensory symptomatic response data from a symptomatic sensory area;
(C) normalizing the symptomatic response data and the asymptomatic response data;
(D) normalizing subjective data; and
(E) determining the attenuation of a somatosensory condition by comparing the normalized asymptomatic data, the normalized symptomatic data, and the normalized subjective data. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
