Abstract: The present invention provides a therapeutic active-motion apparatus that increases Joint-Electricity for improving the active motion of affected shoulder. It is comprised of a straight-arm section, one or more than one arm-fixing strap, a hand-position section, and one or more than one force-applying-interface section, for applying a force toward the affected shoulder joint during the training of active motion to actualize the therapeutic mechanism based on Joint-Electricity Theory, and its application theory “Using the Favorable Component of Joint-Electricity-Generation as the favorable component in motion therapy”. The affected shoulders those with limitation in range of motion and shoulder pains use the present invention can achieve the effects including at least the increase in range of motion that is measurable, and reduction in the shoulder pains.

Abstract: The present invention includes two methods for manufacturing an artificial cartilage and two types of artificial cartilage manufactured thereby, one of the said artificial cartilages can be utilized through implanting surgery fixed into an individual natural joint of an individual, and the other into an artificial joint of an individual joint of an individual before or during implanting surgery. The present invention is invented based on JOINT-ELECTRICITY THEORY created by the present inventor. After the said artificial cartilage is implanted, it can effectively react to the intra-articular dynamic pressure to continuously cause piezoelectricity effect for continuously generating Joint-Electricity, and to generate a sufficient amount of Joint-Electricity during daily living, so as to reduce pain, improve muscular strength, and speed the recovery of active motion ability after surgery.

Abstract: An artificial cartilage was invented based on JOINT-ELECTRICITY THEORY that first in the world created in 2010, and verified in 2011, both by the present inventor, Sue-May Kang. The said artificial cartilage has sleek joint-surface and individualized appropriate shape, is made of proper piezoelectric material, and to be placed into the indication-joints, including at least the natural joints with lack or defect in cartilage and artificial joints, those suffering from impairment in generating Joint-Electricity. After surgical placement (yet, any surgery is not included in the present invention), it can be subjected to the dynamic force within the said joint in its effective range, and thus, continuously generate intra-articular electricity (is the so-called Joint-Electricity), and consequently supplements the wanted Joint-Electricity to the said joint and its related muscles.

Abstract: An assist device for using chopsticks includes a finger holder having two members for fingers holding, a chopstick keeper having two parts connected to the two members of the finger holder respectively, wherein each of the two parts having a position for fixing a chopstick thereon, and an connecting member connected to one of the chopstick keeper and the finger holder for returning said assist device to an original shape. The assist device does keep the chopsticks in a best operating condition even though the user cannot use the chopsticks coordinately. Thus, the assist device can assure the chopsticks are able to pick up food correctly and efficiently even though the finger holder is non-coordinately pressed. Therefore, the assist device helps the user who is disabled to use the chopsticks for easily operating the chopsticks. In addition, the chopsticks can be removed from the chopstick keeper for cleaning, so there is no hygiene problem.

Abstract: A device for helping a disabled person use chopsticks, including two sleeves for holding a pair of chopsticks, a connecting element connected between the sleeves, an operating frame having two opposite ends respectively connected to the sleeves, the operating frame being operated with the hand to move the sleeves relative to each other, thereby causing the chopsticks to act against each other for raising food to the mouth.
