The present invention provides a novel device for portable percutaneous electrical nerve stimulation and electro-acupuncture. In the preferred embodiment, the device consists of a needle/electrode holder that has a linear electrode/needle guide channel and a power supply channel that intersects with the needle/electrode guide channel and serves for insertion of a pin electrode from an electrical generator (PENS unit). The pin electrode will provide an electrical contact with the needle and at the same time function as means for securing the needle in a desire position in the guide channel. The needle remains straight and the extended portion thereof is kept out of contact with the patient's skin.
