Patent ID: 8038579

Claim:
A system for training and evaluating bilateral symmetric force output of upper limbs, comprising: a force application unit of bilateral upper limbs, said unit having at least two force sensors adapted for measuring values of forces exerted by a user's upper limbs; a movable link unit coupled to the force application unit of bilateral upper limbs and having a plurality of movable links; a signal conversion unit coupled to the force sensor adapted for converting the values of the forces exerted by the user into a series of electrical signals; a computing unit having a computer embedded with training and evaluation software and a database module for storing a force value of the user; said computing unit having: a signal fetching card coupled to the signal conversion unit to fetch the electrical signals of the signal conversion unit and forward them to the computing unit in generation of a determination result, wherein the computing unit respectively records values of forces into the database module which were exerted by a left upper limb and a right upper limb and measured by the force sensors, calculates a maximum value of applied force according to the values of forces exerted by the left upper limb and the right upper limb, and configures a preset value of applied force according to a user's condition, the computing unit computing a means for calculating a symmetric index according to the values of the forces exerted by the left upper limb and the right upper limb; and a driving unit driving the movable link unit according to the determination result of the computing unit; wherein the computing unit determines if values of the forces exerted by the left upper limb and the right upper limb of the user reach the preset value of applied force and the symmetric index is within a range of the preset symmetric index according to the determination result, and controls the driving unit to drive the movable link unit to perform the predetermined movements.
