One aspect of the present disclosure relates a system that can quickly and reversibly block conduction in a nerve. The system can include a first nerve block modality that provides heat to the nerve to block conduction in the nerve. For example, the heat can provide the quick nerve block. The system can also include a second nerve block modality that provides an electrical signal to the nerve to block the conduction in the nerve. For example, the electrical signal can provide the reversibility. In some instances, the heat can be provided by an infrared light signal and the electrical signal can be provided by a kilohertz frequency alternating current (KHFAC) signal or a direct current (DC) signal.

Resistively loaded dielectric biconical antenna apparatuses, including systems and devices, that may be used to transmit very short electrical pulses (e.g., nanosecond, sub-nanosecond, picosecond, etc.) into tissue non-invasively at energy levels sufficient to invoke biological changes in the tissue. These resistively loaded dielectric biconical antenna apparatuses may include a resistor ring reducing internal reflection and reducing energy loss, as well as delivering longer pulses (e.g. microsecond to millisecond) to tissue.

A therapeutic apparatus for treating damaged tissue on a limb or body of a subject includes a wearable adapted to cover and be secured to the limb or body of a subject over damaged tissue. The wearable being configured to reduce pressure on the damaged tissue and adapted to deliver one or more treatments selected from the group consisting of heat, oxygen, electrical current, and light to the damaged tissue.

A physical therapy device for pets contains: a current output unit, a comb body, and a conductive platform. The current output unit is electrically connected to a power to supply an output current and control a current value of the output current. The comb body includes a first terminal and a second terminal, a side of the first terminal has a first brushes which are made of a plurality of conductive materials. The first terminal is separately electrically connected to the current output unit, and the second terminal is held by a user. The conductive platform is electrically connected to the current output unit so that the current output unit outputs the current to the pets via the first brushes.
