Novel knit fabric rehabilitation equipment for finger impairment.

[Purpose] Intensive training can at least partially improve finger movement dysfunction observed after stroke or any neurodegenerative disease. Wearable equipment can significantly improve patients' quality of life. However, long-term use of conventional training gloves containing metal can injure joints. In this study, we investigated the safety and efficacy of a novel, metal-free, wearable strength-building device. [Participants and Methods] We enrolled 20 healthy participants in whom we measured grip and pinch strength before and while the equipment was worn. Additionally, we investigated the adverse effects and discomfort experienced while participants wore the equipment. [Results] The grip strength was reduced by approximately 20% while participants wore the equipment. We did not observe any serious adverse events. [Conclusion] The knitting equipment described in this study resists movements associated with gripping the hand and acts on all fingers, and may be useful for rehabilitation to improve finger function during routine activities.
