Description

Muscle strength testing device with stand

The present invention relates to a muscle strength testing device with a bracket, and more particularly to a muscle strength testing device that can be self-supporting and can be moved to a plurality of measurement positions accordingly.

The dynamometer is a professional tool used to assess an individual's muscle strength. It is mainly used in clinical and rehabilitation environments. The dynamometer helps medical professionals assess the patient's muscle status, monitor treatment progress, and develop effective rehabilitation plans.

Dynamometers typically use pressure or tension sensing technology, which can measure the amount of force an individual exerts on a specific muscle or muscle group. Common sensing technologies include piezoelectric sensors, tension sensors, or pressure plates.

Common muscle strength measuring instruments are designed to be portable, making them easy to carry to different places for measuring muscle strength at any time.

These instruments can often be applied to different muscles or muscle groups to provide a comprehensive muscle assessment. This is particularly valuable to rehabilitation professionals, as they can tailor measurements to the specific needs of their patients.

However, conventional muscle measuring instruments require another person to hold the instrument in a handheld manner, which means that an assistant is required during measurement, which causes troubles when conducting assessments alone or in an environment without an assistant.

Because of the reliance on the support of others, it is difficult to ensure consistency between different measurements. The strength or support methods of the assistants may also be different, which may cause a certain degree of variation in the measurement results. In addition, the need for the support of assistants will increase the time and cost of the measurement, which will further lead to an increase in labor costs in a busy medical environment.

In view of the above problems of the prior art, the present invention provides a muscle strength testing device with a bracket, which uses a plurality of components and a steering device to support the muscle strength testing device and move the muscle strength testing device in multiple directions to the desired position.

Muscle strength is one of the key indicators for assessing the user's motor function progress. In clinical practice, hand-held muscle strength testers are often used to provide accurate and quantitative muscle strength information. Compared with traditional freehand testing, they are more accurate and convenient to carry, so they are widely used to assess the user's muscle strength level. However, past studies have shown that the test reliability of hand-held muscle strength testers is low. One of the main reasons is that the tester's own muscle strength is insufficient. If the tester's muscle strength is less than that of the subject, and the tester cannot fix the muscle strength tester in the same position, it will lead to measurement errors.

Continuing from the above, in order to reduce the error of muscle strength measurement, the present invention provides a muscle strength testing device with a bracket, which not only retains the advantages of the hand-held muscle strength tester, but also solves the impact of different muscle strength of testers on the test results, so as to ensure its accuracy and reliability in clinical applications.

In summary, the present invention provides a muscle strength testing device with a stand, which uses two supporting components to connect a supporting body (such as a table or a bed), and sets a turning device to connect the muscle strength testing device. The two components and the turning device enable the muscle strength testing device to be moved in multiple directions to the position required for measuring muscle strength, solving the problem that the conventional muscle strength measuring instrument needs to be supported by an assistant in a hand-held manner, which makes it difficult to ensure consistency between different measurements, and the assistant's strength or support method further causes the measurement results to vary, and solves the problem of increased labor costs due to the need for an assistant.

Therefore, this invention is novel, progressive and can be used in the industry. It should undoubtedly meet the patent application requirements of the Patent Law of our country. Therefore, I have filed an invention patent application in accordance with the law. I hope that the Bureau will approve the patent as soon as possible. I am very grateful.

However, the above is only an example of the present invention and is not intended to limit the scope of the present invention. Therefore, all equivalent changes and modifications made according to the shape, structure, features and spirit described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
