We developed a novel white cane fabricated using aramid-fiber-reinforced plastic. In this study, impact resistance of each canes were evaluated in strength test. In addition, to evaluate physical loads regarding to actual operation, electromyography of upper limb muscles are measured during touch motions with each two cane. These results show that the new cane is less than half the weight, and high impact resistance compared to a conventional cane fabricated using carbon-fiber-reinforced plastic. Moreover, muscle loads of wrist flexion muscles during touch motion can be reduced by about 20%. On the other hand, the load of the extensor carpi ulnaris muscle was increased.
