Description

Multifunctional mobile muscle strength assessment equipment

technical field

The invention relates to a medical instrument, in particular to a multifunctional mobile muscle strength evaluation device.

Background technique

Muscle strength refers to the maximum contraction force of a muscle during exercise. Muscle strength assessment is to measure the contraction force of a muscle or muscle group during active exercise to evaluate the size of the muscle strength, determine the degree of muscle dysfunction, formulate a rehabilitation treatment plan, and evaluate the curative effect of rehabilitation. . As an important detection index in rehabilitation medicine, muscle strength test is often used to evaluate muscle function damage caused by various reasons, and is widely used in the fields of neurology, orthopedics, sports medicine and rehabilitation medicine. The most commonly used and internationally recognized muscle strength assessment method in clinical practice is manual muscle test (MMT). Although the operation of MMT is simple, the classification is relatively rough, often accompanied by errors in the subjective evaluation of the operator. Moreover, the force-measuring instruments adopted, such as a grip dynamometer or a pinch dynamometer, are relatively simple, can only measure hand muscle strength, and have relatively large measurement errors. Better muscle strength testing and training equipment, such as: Power Track II, Computer Interfaced Manual Muscle, Tracker Freedom Wireless Muscle Testing, etc., are expensive, complicated to operate, and difficult to promote and apply in clinic.

At present, the research on the application of smart phone software in the medical field in my country is still in its infancy. With the continuous development and improvement of modern technology, medical program software based on the Android system has broad application prospects. According to another statistics, there are currently 82.97 million people with disabilities in China, and the elderly population has reached 140 million. These two groups are potential demanders for this equipment.
