Increasing hand muscle strength is critical as the population ages. Decreased hand muscle strength, hemiplegia (common in stroke patients) and joint contracture can cause inconvenience in daily life, especially in upper limb movement. After analyzing liquid heating, principles of electricity, and muscle training related products, we found those products to be singular in function. Moreover, they limit movement and can even be dangerous. On the other hand, multifunctional rehabilitation gloves are innovative, electrification, offer comprehensive movement training and improve blood circulation. In the future, after human subject experiments and cooperating with vendors, we hope to be able to promote rehabilitation gloves globally and improve quality of life for stroke patients and/or the elderly.
