Problems solved by technology

But the loosening assembly of the present invention is located at the proximal end of the calf of the knee joint, and it is easy to form an arc-shaped block during the loosening process, resulting in bony collisions; multi-position placement is required to complete multi-directional loosening training; and due to structural limitations, only Fixed at a certain angle for joint mobilization treatment, dynamic mobilization treatment cannot be performed
[0011] The above-mentioned patents and technologies are all part of the detection and training of the three-dimensional active and passive motion of the knee joint. They cannot detect and train the active and passive motion modes during the dynamic motion of the knee joint, and cannot simultaneously detect and train the physiological motion and auxiliary motion during the motion process.

Embodiment 1

[0026] Select the corresponding device according to the left and right sides. Before testing, the machine is calibrated to zero. Release the restrictive structure of each joint, place the thigh on the thigh support (4), place the calf on the calf support (13), flex and extend the knee joint and adjust the rotation center of the knee joint to align with the connecting device (14). Rotate the center, then securely secure the thigh and calf. At this time, the static posture data of the knee joint can be measured, including the angles of varus, varus, and internal and external rotation. It is also possible to fix the knee joint at a certain position, perform static passive detection of the three axes, three sides and twelve directions of the knee joint, observe the movement or relaxation of the specific position of the knee joint, and formulate an appropriate treatment plan.

Embodiment 2

[0028] On the device, active or passive maximal knee flexion and extension. By driving the rotation of the connection device (14), the flexion and extension angle, speed and strength of the knee joint are measured; the moving slide rails (7, 8) cross the fixed slide block group (26) on the fixed slide rail (5, 8) 6) The up and down movement of the upper body, the inward and outward synchronous movement of the moving slide rails (7, 8), and the front and rear synchronous movement of the vertical slide rails (9, 10) can measure the up and down, inside and outside, front and back movement of the calf during the knee joint movement trajectory; the asynchronous movement of the two moving slide rails (7, 8) can detect the inclination degree of the calf during the motion of the knee joint, so as to know the degree of varus and varus of the knee joint during the motion of the knee joint; Rotating slide rails (24, 25) are installed below, which can detect the internal and external rota...

Embodiment 3

[0031] According to the established treatment plan, under the appropriate body position, joint angle, and speed, apply appropriate three-plane translation or three-axis rotation traction and / or resistance to the joint, and perform passive loosening of up and down, front and back, inside and outside, flexion and extension, internal and external rotation, and valgus In addition, patients can be instructed to carry out active training along or against the direction of external force to promote neuromuscular motor control and treat knee joint pain and dysfunction.

[0032] In summary, a knee joint three-dimensional motion detection and training device proposed by the present invention is a device capable of performing active and passive knee joint three-dimensional motion function detection; it is also a device capable of passive, assisting, and active training The equipment can perform common clinical passive training techniques - dynamic and static joint mobilization techniques a...

Abstract

The invention discloses a knee joint three-dimensional motion detection and training device, comprising: a thigh part composed of a thigh fixing device (1), a connecting rod (2, 3) and a thigh supportbracket (4); a shank part composed of fixed sliding rails (5, 6), moving sliding rails (7, 8), vertical sliding rails (9, 10), connecting rods (11, 12) and lower leg support brackets (13); The thighportion and the calf portion are connected by a connecting device (14). The main function of the thigh part is to fix the thigh; The lower leg part can be pulled to realize up-down, front-back, inside-out translational movement, and can also realize inside-out, inside-out, inside-out and inside-out rotation of the lower leg, and the connecting device (14) is responsible for realizing knee joint flexion and extension movement. Thus, the device can realize the three-dimensional motion detection and training of the knee joint, and provides an objective index for the kinematics and dynamics detection of the knee joint injury and disease, and lays a foundation for the implementation, standardization and popularization of the knee joint loosening technology.

Description

technical field [0001] The invention relates to a knee joint three-dimensional motion detection and training device, in particular to a three-dimensional active and passive joint motion detection and training device. Background technique [0002] Pain and dysfunction caused by knee joint injury or disease are common problems faced by orthopedics, sports medicine, rehabilitation medicine, pain, Chinese medicine orthopedics, acupuncture and massage. Therefore, the assessment and treatment of knee joint dysfunction has always been a clinically important issue. The assessment of knee joint dysfunction is mainly the assessment of the range of motion of the joint and the muscle strength of the surrounding muscle groups. The present invention is a device that can perform active and passive three-dimensional motion function assessment of the knee joint; the present invention is also a device that can perform passive and assisted movement , Active training equipment, capable of perf...
