INSTRUCTIONS: * TECHNICAL FIELD The present invention relates to a biaxial weight-bearing ankle joint propensity evaluation device, and more particularly to a high precision that can measure motion sensation, joint position sensation, and power sensation. Evaluation device. [Prior Art] Press, the proprioception refers to the perception of the position or movement of various parts of the body, Φ the introduction of the proprioception by the afferent receptors around the body, such as muscle spindles, joint receptors, skin receptors, High-basin tendons are responsible for providing information such as the perception, position, and strength of the body's movements. Therefore, the proprioception usually includes motor sensation, joint position sensation, and power sensation. Nosocomial sensory injuries are associated with common neuromuscular and skeletal lesions such as age, ligament injury, peripheral neuropathy, and osteoarthritis, in addition to median neuropathy, such as stroke and spinal cord injury. Because 烕 是 is a very complex system that requires a lot of information from a lot of receptors, so in the process of disease development, the proprioception is likely to be damaged at an early stage. Many literatures indicate that different assessment methods can be used to measure the sensation of joint position, including the way in which different joint loads (bearing or non-load bearing), moving the joint from the starting position to the target angle (active or passive movement), = pointing The way the joint is positioned (by moving the contralateral joint or re-swinging to the phase) and how to reposition the joint back to the position (passive or active). When the subject is asked to touch the joint in position (4) 200800106, these changes may affect the angle of the input. A number of different test methods have been developed to measure proprioception, but only for measuring motion sensation, joint position sensation, and power sensation separately. Most of the research on the ankle proprioception is mostly measured without weight bearing, and can not represent the performance under weight bearing conditions; and many rehabilitation programs advocate that the proprioception can be improved by exercise, but very few Evidence • Displaying movement does improve proprioception; in addition, proprioceptive testing equipment includes a wide variety of instruments and test equipment, including commercial isokinetic muscles, electromagnetic field tracers, and other self-designed devices. These commercial devices or self-designed devices have many eye-catching systems, or three modes that are not accurate enough or can not measure the proprioception at the same time; especially, in a similar situation, to evaluate The functional performance of the joints is important. However, most of the evaluations of the ankle's proprioception are mostly measured without weight bearing, which is inconsistent with Lu injury in real life such as falls or ankle sprains.

The first pressure sensing unit (36) is connected to the first pressure sensing unit (36), and the first pressure sensing unit (36) is fixed to the first screw seat (35), so when the subject presses The pressure is transmitted to the first pressure sensing unit (36). When a certain force (for example, 5 kg) is reached, the first pressure sensing unit (36) communicates to the first power unit by the control unit (6). (23) starting the first screw (24) to rotate, to drive the first screw seat (35), when the first screw seat _ (35) moves, the first pressure sensing unit (36) and the first one are driven together柩 abutting (34), and driving the first pivoting seat (34) A member (33) so that then the first holder (3) rotating, and the first nosepiece (4) is also the same pattern, the same operation can both. 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 ankle joint sensory measurement is performed in a weight-bearing state. The rotation axis arrangement of the ankle joint of the subject is on the common line of 10 with the second pivot shaft (42) of the second rotation seat (4), and the rear foot is placed in the hard heel cup embedded in the second rotation seat (4). The front foot is tied to the second seat (4) with a hook and loop fastener. The subject is given a warning by a headset and shields the sound from any servo motor to help the subject to concentrate. The evaluation direction includes the sagittal back and foot curvature, and the inversion and eversion of the frontal plane; or the measurement of the two motion planes simultaneously to simulate the real function. ' For the ankle joint sensation measurement, the subject is supported by the back belt at the waist, 'hip, knee, and foot height. The subject is blinded by an eye mask when subjected to 12 *5. 200800106 • to exclude visual input. The control unit (6) drives either or both of the first power unit (22) and the second power unit (37) to cause the second seat (4) to move slowly at a speed of 〇2 degrees per second. ankle. When the subject perceives the movement and direction of the joint, it is indicated, for example, pressing the switch to test whether the subject can perceive the discontinuous movement and record the minimum joint activity value that detects the motion. This test action must be at a low speed, for example 〇 2 degrees per second; and the range of motion is small, for example, 5 degrees of movement to the sole of the foot. When performing the ankle joint position sensing measurement, the control unit (6) controls either or both of the first power f element (23) and the second power unit (37) to limit the first screw (24) and the first The number of revolutions of the two screws (38) is within a predetermined value\, whereby a second rotation seat (4) is set to rotate within a range of -. Within the range of rotation, the 'second rotation seat (4) can be actively or passively stopped at the target position for two specific times, and the control unit (6) memorizes the position of the target; by the test fork, the ankle joint is active or passive. Copy the position of the target position, force: to measure the position of the joint. When executed, the indication angle is preferably small 'for example less than 2 degrees. This one-step joint position sensation measurement has: the mode "the first mode is the subject's active mode 'the position of the subject' as described in the 'stepping joint position at each random test (ie, indicating the angle), speculation The person must actively copy the position of the ankle joint. First, from the neutral = start position 'in the joint activity range _, the subject at the speed of his choice, 'actively move his foot, then under the direction of the experimenter, stop 'stop in the test position In this position, concentrate on memory and stay for 5 seconds, then 13 200800106 • The ankle moves within the entire range and then returns to the starting position. The subject is then required to automatically copy the test position angle; when the subject indicates that = they have reached the target copy position, they begin collecting data, recording the difference in absolute values between the test position and the copied position. The second mode is the passive mode of the subject, the second seat (4) takes the ankle to a target position, and then maintains 5 private, then the subject is brought back to the neutral position (ie, the starting position), followed by the second rotation Seat (4) takes the ankle to the test position until the subject φ indicates that he has returned to the target position, at which point the position is the sensory position. The operator needs to record the absolute value of the relative distance between the target position and each perceived position as the measurement data. When the ankle joint sensation measurement is performed, the position of the subject is coupled to the first pressure sensing unit (36) and the second pressure sensing by the first rotation seat (3) and the second rotation seat (4) mechanism as described above. The unit (46), the control unit (6) can record the pressure values of the external forces received by the first pressure 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 copying power for 1 second, the job provides enough rest (4) to avoid the fatigue effect, and thereby record the absolute value of the difference between the test force and the copying force of the subject. Finally, the first swivel (3) and the second swivel (4) can be swapped with the treadle (5) to remove the tread (5) first, the first swivel (3) and the second swivel ( 4), ' With the slide (21) of the slide (2), the first slide (13) of the seat (1) slides to the other side, and the vacant position is placed in the step (5). , that is, complete the swap, 200800106 to facilitate the test of the left and right feet.
