Upper extremity wearable device
An upper extremity wearable device includes a pressure sleeve configure to wrap a forearm, a middle finger stimulating electrode and a ring finger stimulating electrode disposed on an inner surface of the pressure sleeve. The middle finger stimulating electrode covers a middle finger stimulating point which is measured from an ulnar styloid process, moving two lateral units, and moving four longitudinal units. The ring finger stimulating electrode covers a ring finger stimulating point which is measured from the ulnar styloid process, moving one lateral unit, and moving five longitudinal units. The lateral unit is a distance from the position of the pressure sleeve corresponding to the ulnar styloid process to a radial styloid process dividing four. The longitudinal unit is a distance from the position of the pressure sleeve corresponding to the ulnar styloid process to an olecranon process dividing twelve.
