[0002] Muscle strength assessment technology is widely used in clinical diagnosis and treatment. As one of the foundations of diagnosis and treatment, it is crucial throughout the entire process, including differential diagnosis, treatment, rehabilitation, discharge assessment, and disability assessment. Its application encompasses muscle strength abnormalities caused by musculoskeletal and neurological disorders, and is closely linked to patients' normal lives, work, and even their safety. Common conditions such as tendon injuries, osteoarthritis, stroke, and poliomyelitis all present with muscle strength abnormalities, and the results of these abnormalities can guide the development and implementation of more accurate and targeted examinations and treatment plans.

[0003] Existing muscle strength assessment devices require different force measurement components for different movements. For example, measuring pinch force requires replacing the sensor assembly of the device with a pinch force sensor; measuring grip force requires replacing the sensor assembly with a grip force sensor; and measuring tension requires replacing the sensor assembly with a tension force sensor assembly. Consequently, these devices are complex to operate, difficult to implement, and require a lot of space, hindering widespread clinical application and patient self-assessment and training supervision at home.

[0004] The data collected by the existing mechanical muscle strength assessment device needs to be transmitted to a computer or other display device for display, which makes it inconvenient to view the collected data in a timely manner. Utility Model Content
