本研究主要是設計出一台機器設備量測受試者下背部組織的水平阻力及機械性值，並加以分析找出和下背痛臨床症狀相關的可量測指標。
下背部疼痛是現代人常見的疾病之一，約有四成的人會得到下背部疼痛，它會嚴重的影響患者的平日生活作息，現有的下背部疼痛的診斷方法，包含利用量測下背部肌肉的壓力閾值做出標準，而跟標準差異很大的即被判定為下背部異常，此方法容易因每個人的忍耐範圍而有差距；也有人用肌電圖(Electromyography)跟肌械圖(Mechanomyography)的量測來判斷下背部肌肉的狀態，但這兩個量測特徵沒有直接對應到下背痛的指標；此外，也有人使用斷層掃描觀察病人跟正常受試者下背部肌肉比較的情形，可是這些量測花費太多金錢跟時間。以上方法也都有一個無法量化的問題。本研究則希望提出一個可以量化的指標來對應下背部疼痛的症狀，讓下背部痛症狀的判斷更加客觀。
本研究將會設計建造出一個機械設備，以下壓背部組織的方式量測下背部組織的水平阻力，並藉由量測到的數據進行分析且將結果繪製成四個方向背部阻力分析圖，方便觀察分析，最後用來找出下背痛臨床症狀相關的可量測指標。
本研究成功藉由量測水平的阻力來分辨出仿體跟豬腳內部的性質差異。
本研究的結果創新了一種可量測水平阻力的機器，讓我們可以利用量測表面水平阻力得知內部組織情形。未來可以把這個方法用至人體背部的量測。

This study investigates measurable indicators related to clinical symptoms of lower-back pain with the horizontal resistance of lower back by mechanical device.
Lower back pain is one of the most common diseases in modern people. About 40% of people have experienced lower-back pain, which can seriously affect the daily life of patients, in their lives. People have been studying the diagnosis of lower-back pain, such as the use of pressure measurement under lower-back muscles to make the standard threshold of pressure, while the value which is very different from the lower back was judged to be abnormal. However, this method is easy to have a gap due to the tolerance range of each person. Some people used EMG and MMG ( Electromyography and Mechanomyography) to determine the status of the lower back muscles. But these two measurement features do not directly correspond to the syptoms of lower back pain. In addition, some people used tomography to observe the patient's lower back muscles compared with normal subjects. But the cost is too high and the machine is not available to everone. These measurements all show the difference in the mechanical properties of the lower back between the patient and the normal subject, but neither can be quantified to justify the result.
This study will design and construct a robotic arm to measure muscle tension and mechanical values of the lower back muscles, analyze the measured data and place the results on a tension distribution figure, and finally find out measurable indicators related to clinical symptoms of lower-back pain.
This study succeeded in distinguishing the nature of the internals of the phantom and the pig's foot by measuring the resistance of the level.
We have invented a machine that measures horizontal resistance, allowing us to measure internal surface conditions by measuring the horizontal resistance of the surface. This method can be used in the future to measure the back of the human body.
Keywords: lower-back pain, tissue resistance, lower-back detection.
