Body Sense The damage of proprioception is related to central neuropathy, such as ZH, Zhao injury, and other common neuromuscular bone pathological changes such as age, belch injury, and osteoarthritis. Because, it is a very complicated system, it needs to receive information from many receptors, and therefore, in the process of disease development, the proprioception is attacked and damaged in the early stage. Many literatures indicate that the sensation of the joint position can be measured in different joint load conditions (bearing or non-load bearing), and the way the knot moves from the starting position to the target angle (active two, the way out of the joint position ( By re-posing the contralateral joints to the same position) and how to reposition the joints back to the position (passive or active). When the subject is asked to judge the joints in space = 5 1287977 %, these Changes can affect the angle of the input. Many different test methods have been developed to measure the proprioception, but it is limited to measuring the motion sensation, joint position sensation, and power sensation separately. Most of the research on the ankle sensation is mostly It is not measured under load-bearing conditions without weight-bearing; and many rehabilitation programs advocate that motion can be used to improve proprioception, but there is very little evidence that exercise can actually improve proprioception; The ontology sensory test _ equipment extensively contains a variety of instruments and test equipment, including commercial isokinetic strength gauges Electromagnetic field trackers and other self-designed devices. These commercial devices or self-designed devices have many limitations, or three modes that are not precise enough or can not measure the sense of the body at the same time; especially - in A similar to the actual situation, it is very important to evaluate the functional performance of the joints. However, most of the evaluations of the sense of the foot are measured in the absence of weight bearing, and the fall or foot in real life. Sprains, etc. Φ Injury is not satisfactory.

When the first screw seat (35) moves, the first screw seat (35) will drive the first a pressure sensing unit (36) and a first pivoting seat (34), such that the first splicing seat (34) drives the first lever (33) to rotate the first cock (3); and the second The rotary seat (4) is also in the same mode, and both can be operated simultaneously. The method of the present invention is that when the subject stands at the seat surface (11) of the seat (丨), the measured foot rests on the second seat (4), and the untested foot steps on the step seat. (5) The body joint sensory measurement is performed in a state of weight bearing. The rotation axis arrangement of the subject's stepping joint is on a common line with the second pivot shaft (42) of the second rotation seat (4), and the rear foot is placed on the second rotation seat (4) in the hard _ with the cup; The buckle is tied to the second knob (4). By means of a headset, the subject is given a warning prompt and shields the sound of any servo motor to help receive financial attention. The evaluation direction includes the domain _ the back of the foot and the sole of the foot (four)' and the inversion and eversion of the frontal plane; or it is measured in combination with the two motion planes to simulate the real function. When performing ankle joint sensation measurement, the height of the buttocks, knees, and feet is buried. The support is supported by the waist = 12 1287977* • The eye is covered with an eye mask to exclude visual input. Control unit (6 Driving either or both of the first power unit (22) and the second power unit (37) to cause the first rotary seat (4) to slowly move the foot at a rotational speed of 〇 2 degrees per second. When the tester perceives the movement and direction of the joint, it is indicated, for example, by pressing a switch to test whether the subject can perceive the discontinuous movement, and the traveler records the minimum joint activity value that detects the motion feeling. The action must be at a low speed, for example 0.2 degrees per second; and the range of motion is small, for example 5 degrees in the direction of the sole of the foot. • The control unit (6) controls the first power unit (23) and the first when the joint position sensory measurement is performed. Either or both of the two power units (37) are configured to limit the number of revolutions of the first screw (24) and the second screw (38) to a predetermined value - thereby making the first rotary seat ( 4) is set to rotate within a certain angle, at, Within the range of motion, the second rotary seat (4) can be actively or passively stopped at a target position for a specific time, and the target position is memorized by the control unit (6); the test subject is actively or passively copied by stepping on the joint. The ability of the target position is used to measure the position and feel of the pedal. When performing, the indication angle is preferably small, for example, less than 2 degrees. There is two modes of the ankle joint position measurement, the first mode. For the subject's active mode, the position of the subject is as described above. In each stochastic test of the joint position (ie, the indicated angle), the subject must actively copy the ankle joint position. First, from the neutral starting position, Within the range of joint mobility, the subject actively moves his or her foot at the speed of his choice, and then, under the direction of the experimenter, stops the position in the test, concentrates on this position and stays for 5 seconds, then 13 1287977 The ankle moves over the entire range and returns to the starting position. Then, A, the person is required to automatically copy the test position angle; when the subject indicates that the target has been reached After copying the position, it starts collecting data and records the difference between the absolute position of the measured position and the copied position. The second mode is the passive mode of the subject, and the second rotary seat (4) takes the foot to a target position. And then for 5 seconds; then the subject is brought back to the neutral position (ie the starting position), then the second seat (4) takes the ankle to the test position until the subject indicates that he has returned to the target position Up to now, the position is the absolute value of the relative distance between the target position and each sensed position, as the measurement data. When performing the ankle joint sensation measurement, the position of the subject is as described above. The first rotating seat (3) and the second rotating seat (4) mechanism are coupled to the first pressure sensing* unit (36) and the second pressure sensing unit (46), and the control unit (6) can record the first pressure The pressure value of the external force received by the sensing unit (36) and the second pressure sensing unit (46). At the beginning, the test subject applies a test force to the second rotary seat _ (4), records the value of the test force through the control unit (6) and recovers, and then asks the subject to generate the same force, which is called the replication force. , to maintain the replication power for ten seconds, and then provide enough rest time to avoid fatigue effect, and thereby record the absolute value of the difference between the test force and the replication power of the subject. Finally, the 'first rotation seat (3) and the second rotation seat (4) can be replaced with the tread seat (5). The tread seat (5) is first removed, and the first rotation seat (3) and the second rotation seat ( 4), by the slider (21) of the sliding seat (2), the first sliding rail (13) of the seat body (1) slides to the other side, and the vacant position is put into the pedal seat (5). That is to complete the swap, 1287977 to facilitate the test of the left and right feet. BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a perspective view of the present invention.
