Electra 2 & 4 Channel Electrotherapy is a professional electrotherapy system designed for a wide range of physiotherapy, pain-management, muscle stimulation, and rehabilitation applications. Available in 2-channel and 4-channel configurations, Electra provides multiple types of therapeutic currents for the treatment of painful conditions and for muscle stimulation and rehabilitation. The system supports diadynamic, faradic, pulse, direct, bipolar, and interferential currents. Interferential current helps deliver low-frequency antalgic or motor-stimulating currents to deeper tissue levels by using higher frequencies to reduce skin impedance. Electra features independent channels, preset treatment protocols, customized programs, and treatment-phase sequencing for each channel. Safety controls automatically deactivate the output current if an electrode is accidentally detached, helping provide controlled treatment operation. Both models feature a 7-inch touchscreen for convenient operation and treatment selection.
