Description

[Purpose] The purpose of this study was to assess the practical use of a prototype cane which quantitatively measures loads using a strain gauge. [Subjects] Ten healthy adults were recruited. [Methods] The reliability of the load-measuring cane was assessed using a universal testing machine. For the practical use assessment, cane loads during gait were measured and analyzed using the intraclass correlation coefficient (ICC). [Results] The correlation between the output voltage of the load measuring cane and the load measured by the universal testing machine was excellent (r=0.99~1.00). The hysteresis measurement error was within 2-5%. In addition, the ICC of the healthy subjects exceeded 0.8. These results indicate the load-measuring cane has excellent reliability. [Conclusion] The load-measuring cane is simple and inexpensive and it may become a useful clinical assessment device. <br>
