Description

Apparatus for Tremor measure of fingers}

The present invention relates to an apparatus for measuring a finger tracer of a subject, and more particularly, attaches a tremor detection sensor equipped with a sensor that detects hand shaking on a subject's finger and wrist in an unrestrained state, and wears it on a wrist. By collecting and storing the sensor detection data through the watch type data collection device, it is transmitted to the diagnosis computer through wired / wireless communication, so that the tester data for providing the biological data for diagnosing the movement disorder of the test subject. It relates to a measuring device.

As age increases, people are more likely to have chronic diseases and have difficulty in daily living activities (ADL). The health problems of the elderly are becoming social problems with the increase of the elderly population. In particular, senile neurological diseases such as Parkinson's disease and stroke have no obvious treatment, which is causing a deterioration in the quality of life of the elderly and a great economic burden on the family.

As a method for measuring the clinical condition of Parkinson's disease, the clinician tests the patient's exercise ability in a prescribed manner, visually examines and grades the exercise ability through questionnaires and questionnaire results. There are four methods. Among them, UPDRS (Unified Parkinson's Disease Rating Scale) is the most widely used method and consists of 42 items in total. Each item consists of 0 ~ 4 levels. This clinical status determination method can be analyzed differently depending on the clinician's skill, and patients can give different answers for each patient even if they have the same size objectively in questionnaire survey or questionnaire. There is a need for objective diagnostic parameters and analysis results.

The prior art developed by this necessity is the US 'Cleveland Medical Devices Inc.' is a wireless system for analyzing movement disorder symptoms such as tremor, and worn on the finger during the motor task according to the instructions shown in the software.
