Abstract: An apparatus for paddle training. The training teaches the student to limit their wrist motion while swinging their paddle. The paddle training apparatus with a wrist cuff that surrounds the wrist and forearm of the student, a connecting member with a cuff attachment element. The cuff attachment element is removably attachable to the wrist cuff and the cuff attachment element removably receives the connecting member. A paddle attachment element fixedly attached to the other end of the connecting member and the paddle attachment element facilitates removable attachment of the connecting member to the paddle.

Abstract: In one aspect, implantable wireless microstimulators are described herein. In some embodiments, a microstimulator described herein includes an energy harvesting circuit configured to receive an input signal and generate an electrical signal based on the received input signal. The microstimulator further comprises a diode rectifier in series with the energy harvesting circuit. The diode rectifier is configured to rectify the electrical signal. The energy harvesting circuit and the diode rectifier can be encapsulated within a biocompatible electrically insulating material. Additionally, in some cases, an electrical interface is exposed through the biocompatible electrically insulating material. A microstimulator described herein can also include a nerve cuff. The nerve cuff can be configured to receive a monophasic neural stimulation pulse through the electrical interface of the micro stimulator.
