| dc.description.abstract | Nowadays, electronic technology is constantly advancing, and there is a growing trend towards measuring at increasingly smaller and more precise scales. There is a significant demand for efficient and accurate detection methods, leading to the gradual replacement of traditional contact-based measurements with optical measurement technology. Optical measurement offers advantages such as non-contact, high precision, and fast speed, and it has been widely applied in various fields, including the semiconductor industry, microelectromechanical systems (MEMS), and medical applications.
This paper focuses on using optical measurement technology to study hand tremors in patients with Parkinson′s disease, in conjunction with acupuncture treatment by Dr. Chen Fang-pei at Taipei Veterans General Hospital. The study collected data from 326 patients with limb tremor symptoms in the neurology outpatient department, out of which 205 were confirmed to have Parkinson′s disease through TroDAT testing. Among them, 13 Parkinson′s disease patients participated in a two-month warm scalp acupuncture treatment, three times a week, resulting in a total of 24 acupuncture sessions over the two months.
Using the vibration moiré test equipment in this paper, the hand tremor values of the 13 Parkinson′s disease patients were measured before and after acupuncture treatment. Amplitude values were obtained through Fourier transformation, and integration was performed individually for each Hertz between 1 to 10 Hz. This integrated value is referred to as the tremor value in this paper. The Y-axis value was defined as the tremor change after acupuncture treatment, obtained by subtracting the tremor value after acupuncture from the tremor value before acupuncture. The X-axis value at Y=0 was used as the threshold value, serving as a determining parameter. Analyzing the data, it was found that when X is greater than the threshold value, the tremor value after acupuncture decreases, whereas when X is less than the threshold value, the tremor value after acupuncture increases. The slope was defined as the effectiveness of acupuncture treatment, and a larger negative slope indicates better acupuncture efficacy. This is because as X-axis (tremor value before acupuncture) increases by 1 unit, the Y-axis value (tremor change after acupuncture) becomes more negative, indicating a higher level of tremor reduction through acupuncture treatment. Therefore, a more negative slope represents higher effectiveness, and the acupuncture effectiveness of these 13 subjects was found to be 78.94%. This device provides objective diagnosis for physicians.
The effective proportion significantly increases when considering the threshold value. Taking subject 1 as an example, when considering the threshold value, the effective proportion is 0.92, while without considering the threshold, it is 0.58. This demonstrates that the threshold value is an important determining parameter for acupuncture treatment. If the tremor value is below the threshold value, the patient is not suitable for acupuncture treatment. | en_US |
