“…Pressure sensors have been used in the evaluation of local tenderness with algometry ( Fenton et al, 2009 ). Some studies used pressure sensors to quantify abdominal palpations ( Katsuki et al, 2015 ). In the work ( Fenton et al, 2009 ), the authors focus on the chronic pelvic pain (CPP) to perform the study of pain pressure threshold (PPT) of the lower anterior abdominal wall in CPP patients; and to determine the range and distribution of values at every 14 site, and the clinical utility of using PPT in a definition of termed myofascial pain syndrome (MFPS).…”

“…However, our proposed system is an integrated approach to continuously keep track the palpation force and location information for further diagnosis. In the work ( Katsuki et al, 2015 ), the authors design the system, which makes use of a motion capture system and a thin film force sensor mounted at a glove, for an abdominal palpation procedure to measure the depth and the force/pressure at the same time during abdominal palpations. However, in the system, the plural infrared cameras and reflective markers are required to setup the testing environment.…”

An abdominal physical examination is one of the most important tools in evaluating patients with acute abdominal pain. We focused on palpation, in which assessment is made according to the patient’s response and force feedback. Since palpation is performed manually by the examiner, the uniformity of force and location is difficult to achieve during examinations. We propose an integrated system to quantify palpation pressure and location. A force sensor continuously collects pressure data, while a camera locates the precise position of contact. The system recorded, displayed average and maximum pressure by creating a pressure/time curve for computer-aided diagnosis. Compared with previous work on pressure sensors of quantifying abdominal palpation, our proposed system is the integrated approach to measure palpation force and track the corresponding position at the same time, for further diagnosis. In addition, we only make use of a sensing device and a general web camera, rather than commercial algometry and infrared cameras used in the previous work. Based on our clinical trials, the statistics of palpation pressure values and the corresponding findings are also reported. We performed abdominal palpation with our system for twenty-three healthy participants, including fourteen males and nine females. We applied two grades of force on the abdomen (light and deep) by four-quadrant and nine-region schemes, record the value of pressure and location. In the four-quadrant scheme, the average pressures of abdominal palpation with light and deep force levels were 0.506(N) and 0.552(N), respectively. In the nine-region scheme, the average pressures were 0.496(N) and 0.577(N), respectively. Two episodes of contact dermal reaction were identified. According to our experiment statistics, there is no significant difference in the force level between the four-quadrant and nine-region scheme. Our results have the potential to be used as a reference guide while designing digital abdominal palpation devices.

“…Park et al (2016) used multiple-sensors to detect reaction force while walking using the original pressure sensor to design a pressure detection system. Katsuki et al (2015) designed a sensor system for an abdomen palpation procedure in traditional medicine. The sensor system makes use of the custom-designed glove, in which the detecting circuit mounted on, to measure the depth and the force during the abdominal palpation.…”
