There are several advantages of this technology that are obvious because they go hand in hand with the reasons why exoskeleton hands were invented. Many orthotic robots have been created for rehabilitation purposes. The authors of the article “Current Hand Exoskeleton Technologies for Rehabilitation and Assistive Engineering” demonstrate this by explaining that robotic hands “can provide effective repetitive training for rehabilitation” (pp.807). Therefore, with the help of this type of therapy, the affected hand has the possibility of regaining some or all functions without the help of the device. Exoskeleton hands give people the ability to use their damaged hand even while wearing the device. Teruhisa Onishi, Tatsuo Arai, Kanji Inoue, and Yasushi Mae explain in their article that wearing the device can be used to “integrate degenerated or lost physical functions or to augment existing physical functions” (p.1). For example, many older adults lose strength in their hands as they age and have difficulty using simple things like remote controls. Wearing the exoskeleton hand gives these individuals the strength to do the kinds of things they couldn't do without
