บทคัดย่อ: | Objective: To focus on a device development for measuring the weight-bearing on feet while simultaneously reporting data on smartphone usage. Secondly, the output data from this device are tested for the accuracy. Methods: Researcher used eight pieces of 50 kg Body Load Cell Weighing Sensor Resistance strain Half-bridge Original (four pieces per foot), two pieces of HX711 amplifier, MCS-51 AT89 C51 microcontroller and HC-05-Bluetooth to develop the device. This device that is called the Wireless Weight-Shifting Detector (WWSD) is used to measure weight-bearing on feet by being attached to sandals. The output data are simultaneously reported on smartphone via line-graphs [load (kg) per sampling data] and numeric by FootpressV1 application. The device was tested using accurate measuring data with standard weights and calculated in percentage of accuracy (%). After that, WWSD was used to compare the weight-bearing measurement during standing with forceplate (AMTI; OR6-7 Platform). Results: The percentage of accuracy of WWSD was more than 97% and the error values from the measuring standard weights ranged under ±0.23 kg. The accuracy of measurement was more than 95% when compared with the force plate. Conclusion: WWSD can report simultaneously the weight-bearing on feet with rather accurate data on smartphone. It may be helpful in assisting physical therapists while training patients in clinic. © 2018 Tossaphon Jaysrichai. |
