Problems solved by technology

Because there are many keys on the traditional keyboard, there is usually no need for too complicated operations when performing the detection of motion functions, and for people with poor eyesight, it takes a certain amount of time to find the key to be pressed among the many keys, resulting in test Results do not reflect problems with motor function
Moreover, traditional keyboards are large, inconvenient to carry and need to be placed on a larger plane
In the test, the subject should take a sitting position, relax and straighten the upper body, and then type the keyboard, which is difficult for some patients with movement disorders

Embodiment Construction

[0016] Now in conjunction with accompanying drawing, the detailed content of the present invention is described as follows:

[0017] Fig. 1 shows a schematic diagram of the structure of the device according to the present invention. The device 1 for detecting hand movement function according to the present invention includes a host 3 , a keyboard 2 , and an output device 4 . In one embodiment of the present invention, the host 3 includes a frequency generator 31 , a timer 32 , a memory 33 and a controller 34 . In operation, the frequency generator 31 generates a frequency, and the timer counts time based on the frequency signal. Striking the keyboard 2 generates an input signal, and the timer 32 starts counting, and stores the corresponding data in the memory 33. When the keyboard 2 is struck here, a second input signal is generated, and the timer 33 stops counting, and the controller 34 calculates the time between the two input signals according to the data in the memory, a...

Description

technical field [0001] The invention relates to medical equipment, in particular to a device for detecting hand movement ability and a method for using the device. Background technique [0002] Parkinson's disease (PD) is a relatively common neurodegenerative disease and one of the main causes of disability in middle-aged and elderly people. Its prevalence gradually increases with age, 1% among people over 50 years old, and 2% over 60 years old. The etiology and pathogenesis of Parkinson's disease have not been fully understood so far, and it is currently considered to be closely related to factors such as genetics, environmental toxins, oxidative stress, excitotoxins, nervous system aging, autoimmunity, and cell apoptosis. The main pathological change of Parkinson's disease is the degeneration of dopaminergic neurons in the substantia nigra-striatum, which loses its balance and facilitates voluntary movement, resulting in typical clinical motor symptoms such as stiffness, ...
