SI23136A - Static splint for measurement of plantar and dorsal flexion intensityof ankle joint - Google Patents

Abstract

A static splint for measurement of plantar and dorsal flexion of ankle joint is solving the technical problem by means of an adaptable mechanical framework and a torque sensor (13). The latter measures torque during extension and flexion of the ankle joint. Two knee splints (4) are height-adjustable by using a catch release mechanism (5) operating according to the principle of eccentric. A seat (3) is height-adjustable via a screw seat mechanism (6). Thus the mechanical framework is fully adaptable to body dimensions of a person under measurement to assure, in this way, better measuring characteristics of a test that the person under measurement is undergoing. A torque sensor (13) is connected with a personal computer (16) via a USB cable (15).

Description

STATIC SUPPORT FOR MEASURING THE STRENGTH OF PLANTARY AND DORSAL FLEXIONS OF THE SKIP joint

The subject of the invention is a static support for measuring plantoma strength and dorsal flexion of the hip joint, which enables quick, simple and accurate analysis of the flexion and extension function of the hip joint.

A technical problem is the construction of a measuring device that combines a flexible mechanical frame and a computer-aided sensing element to change plant force and dorsal flexion of the hinge joint.

The invention makes it easy to measure various force parameters that are extremely important in medical and sports diagnostics for analyzing the functional status of the joint-neuromuscular system of the hip joint.

Innovation is the so-called static support for changes in plantoma force and dorsal flexion of the hip joint (SOG). It is a biomechanical measuring device that is useful for the accurate and reliable evaluation of the functionality of the joint, either of healthy people or of patients in the medical and kinesiology fields. SOG allows kinesiologists and medical professionals to modify and evaluate various deficits (injury, surgery, neurological disease, aging, etc.) or the effects of exercise (physiotherapy, sports, research, sports diagnostics, injury prevention, etc.).

There are many methods used in sports and clinical practice for plantar changes and dorsal flexion of the hip joint, but their use is limited because they are mostly complex, multipurpose, non-portable and expensive systems. In practice, many tests are used to measure plantar force and dorsal flexion of the hip joint, which are divided into static and dynamic. Static power meters developed so far may, by their function, be impractical or too expensive and so inaccessible to many who might need them. Isokinetic devices (Biodex System 4, Con-trex MJ, Lido, etc.), which, in addition to all additional features, allow for plantation force throwing and dorsal flexion of the hip joint, are very expensive and more difficult to access. Compared to the mentioned existing systems, the added value of our innovation is, among other things, the reduction of functionality to essential parameters and the simplification of both the mechanical as well as the usability and algorithmic functions of the system.

The invention for which we wish the patent is a static support for changes in plantage force and dorsal flexion of the hip joint with computer support. A key part of the system is a sensor mounted in the frame, which enables a very accurate measurement of the torque in the jump joint produced by the gearbox by extending and flexing the jump joint. Throughout the measurement, signals are transmitted to a PC through which the signals are captured, stored and subsequently processed.

With the described innovation, the technical problem is solved in such a way that the abutment is fully adaptable to the body dimensions of the pendulum and thus enables optimal torque variation in the jump joint via the torque sensor and mechanical frame. This provides complete information on plantoma force and dorsal flexion of the hip joint. The captured signals further provide us with many options for later analyzes. The invention will be described in the drawings showing:

The invention consists of a basic frame 1, which is made of rectangular metal profiles, is rectangular in shape, and is laid on the floor. The base frame 1 is one and a half meters long and one meter wide. It has a transverse rectangular metal profile in the middle and another in the middle between the center and front profiles. Between the center profile of the base frame 1 and the rear profile of the base frame 1, three circular metal guides 10 are longitudinally fastened. pressed rubber feet one centimeter high.

In the longitudinal profile of the base frame 1, the upper part of the frame 2 is vertically positioned at the location of the second front middle-to-front transverse profile. square profile.

Guide rails 10 have a rectangular seat attachment that is wide enough to extend over all three rails and twenty inches long. The seat attachment is secured to the selected position in the longitudinal position by guides with a hand screw 11, which is screwed into the center guide 10. The seat mechanism 6 for raising and lowering the seat 3 is secured to the seat extension 3. The seat mechanism consists of a mother part and a screw thread rod covered with a round tube mask. Seat 3 is square in shape, measuring fifty times by fifty centimeters, with a metal base and upholstery. Seat 3 is continuously raised or lowered by rotation of the parent part of the described mechanism.

Both side guides 10 are fitted on each side with screw-fastened protective covers 12. These are rectangular metal profiles that extend over one-third the width of the base frame 1 and half the base frame 1 in length.

At the top of the frame 2, knee supports 4 are mounted on the vertical profiles 4. The knee supports 4 are made of two square metal profiles; one running along the vertical profile of the upper part of the frame 2 and the other perpendicularly bolted to the first and facing inward. The latter is supported by two semi-circular supports, which are facing down and placed longitudinally. They are twelve centimeters long, ten centimeters wide, and on the inside they are padded with neoprene (may also be other soft material like foam, fillet, etc.). The entire thigh supports 4 are adjustable in height as they slide along the vertical profiles of the upper part of the frame 2. In the selected position, they are fixed by a fastening mechanism 5 mounted on the thigh support 4, where it runs along the vertical profile of the upper part of the frame 2. Attachment-release mechanism 5 has an eccentric handle that acts when, when the handle is pressed into the lower position, the eccentric portion is pressed against the vertical profile of the upper part of the frame 2 and locks the knee support 4 in the selected position.

The foot supports 4 also vertically align the foot supports 7, which are located below the upper part of the frame 2. The foot supports 7 are rectangular, made of metal, fifteen centimeters long, seven centimeters wide. On the rear side, they have a six-centimeter-high edge attached to the lateral axis 8 on the outside and the central axis 9 on the inside. The foot supports 7 rotate about an axis consisting of a lateral axis 8 and a central axis 9. Side axis 8 is an axial screw with an interface that connects the foot supports 7 with the vertical profile of the upper part of the frame 2. The center axis 9 has two axial screws, each on one side of the interface, and connects the two foot supports 7 with each other.

The supports for the foot 7 are connected to the upper part of the frame 2 via the lateral bearing axis 8, and the base frame 1 is connected through the central bearing axis 9. The two supports of the foot 7 are movable through the two bearing axes 8, 9. With the base frame 1, the foot supports 7 on the front are connected to the torque sensor 13, which measures the torque as the gearbox pulls out and flexes the jump joint. Wheel 14 is mounted on the base frame 1 to facilitate the movement of the support. From the torque sensors 13 runs a USB cable 15 that connects to a PC 16.
