Abstract
The present invention relates to a system for measuring lower extremity muscle strength, and more particularly, to a system for measuring lower extremity muscle strength which can effectively measure or train lower extremity muscle strength by means of a simpler method.
Claims17
A system for measuring lower extremity muscle strength, comprising:
- a sitting part on which an object to be measured sits, wherein the sitting part is a chair, table, or flat surface;
- a sensing unit mounted on the sitting part or at a portion of the object to be measured contacting the sitting part, wherein the sensing unit senses whether the object to be measured is separated from the sitting part;
- a ground reaction force measuring unit measuring over time a first and a second ground reaction forces generated by lower extremities of the object to be measured, the ground reaction force measuring unit comprising:
- a first ground reaction force measuring unit configured to measure the first ground reaction force of one of the lower extremities;
- and
- a second ground reaction force measuring unit configured to measure the second ground reaction force of the other of the lower extremities;
- and a control unit,
- wherein the control unit is configured to determine a first timing when a sum of the first and the second ground reaction forces is largest and confirms the first timing as a timing of separation, which is defined as a timing at which the object is separated from the sitting part, and wherein the control unit is configured to determine a paralysis state for each of the lower extremities based on sizes and a ratio of the first and the second ground reaction forces at the timing of separation.

A system for measuring lower extremity muscle strength, comprising:
- a sitting part on which an object to be measured sits, wherein the sitting part is a chair, table, or flat surface;
- a posture measuring unit configured to measure a posture of the object to be measured;
- a ground reaction force measuring unit disposed at a lower portion of the object to be measured and configured to measure a ground reaction force generated by one of lower extremities of the object to be measured;
- and
- a control unit,
- wherein a lower extremity muscle strength of the object to be measured is determined based on the ground reaction force at a moment where the object to be measured is separated from the sitting part or a ratio of the ground reaction force;
- and
- wherein the control unit is configured to confirm a timing and the ground reaction force when the object to be measured is separated from the sitting part and determines a paralysis state of the lower extremity.
