Abstract

Disclosed herein is an apparatus for early detection of paralysis based on motion sensing. The apparatus includes: a sensing part which detects motion characteristic values of at least one left distal end and at least one right distal end of upper or lower limbs of a patient; a motion disorder determination unit which determines whether a difference between a sum of the motion characteristic values of the at least one left distal end and a sum of the motion characteristic values of the at least one right distal end, detected by the sensing part for a certain period of time, exceeds a reference value. The motion disorder determination unit determines whether a patient'"'"'s motion is abnormal based on a difference in motion characteristics of distal ends, such as left and right wrists and ankles, and the like, for a certain period of time, thereby enabling detection of a stroke at an early stage. In addition, sensors of the sensing part may be attached to the hands and feet, and worn on the wrists and ankles like watches or anklets, thereby improving convenience.

Claims

1. An apparatus for early detection of paralysis based on motion sensing, comprising:

a sensing part configured to detect motion of at least one left distal end portion and at least one right distal end portion of upper or lower limbs of a patient; and

a motion disorder determination unit configured to determine whether a difference between a sum of motion characteristic values of the at least one left distal end portion and a sum of motion characteristic values of the at least one right distal end portion exceeds a predetermined reference value wherein both the motion characteristic values of the at least one left distal end portion and the motion characteristic values of the at least one right distal end portion are determined based on motion detected by the sensing part for a certain period of time.

2. The apparatus according to claim 1, wherein the sensing part comprises a first communication unit for transmitting information of detected motion of the at least one left distal end and the at least one right distal end.

3. The apparatus according to claim 1, further comprising:

an alarm unit for warning of a motion disorder when the motion disorder determination unit determines that the difference between the sum of the motion characteristic values of the at least one left distal end and that of the at least one right distal end exceeds the predetermined reference value.

4. The apparatus according to claim 3, wherein the alarm unit comprises a second communication unit for transmitting a signal containing information regarding the motion disorder.

5. The apparatus according to claim 4, further comprising:

a display unit configured to display the information regarding the motion disorder received from the second communication unit.

6. The apparatus according to claim 1, wherein the motion characteristic value of the distal ends comprises any one of velocity, acceleration, and distance moved.

7. The apparatus according to claim 1, wherein the at least one distal end corresponds to the at least one right distal end.

8. The apparatus according to claim 1, wherein the sensing part includes at least one gyroscope.

9. An apparatus for early detection of paralysis based on motion sensing, comprising:

a sensing part configured to detect motion of at least one distal end of upper or lower limbs; and

a motion disorder determination unit configured to determine whether a difference between a sum of motion characteristic values of the at least one distal end detected by the sensing part for a first predetermined time period and a sum of motion characteristic values of the at least one distal end detected by the sensing part for a subsequent second predetermined time period exceeds a predetermined reference value.

10. The apparatus according to claim 9, wherein the sensing part comprises a first communication unit for transmitting information of motion of the at least one distal end.

11. The apparatus according to claim 9, further comprising:

an alarm unit for warning of a motion disorder when the motion disorder determination unit determines that the difference between the sum of the motion characteristic values of the at least one distal end detected by the sensing part for a third predetermined time period and the sum of motion characteristic values of the at least one distal end detected by the sensing part for a subsequent fourth predetermined time period exceeds the predetermined reference value.

12. The apparatus according to claim 11, wherein the alarm unit comprises a second communication unit for transmitting a signal containing information regarding the motion disorder.

13. The apparatus according to claim 12, further comprising:

a display unit configured to display the information regarding the motion disorder received from the second communication unit.

14. The apparatus according to claim 9, wherein the motion characteristic value of the distal end comprises any one of velocity, acceleration, and distance moved.
