Using Burst Modality Medium Frequency Alternating (Russian and Aussie) Currents with Isokinetic Training

Abstract

Isokinetic exercises are a type of exercise that can be performed both concentrically and eccentrically at various angular velocities while applying resistance to the muscles at each point of the range of motion. These exercises are known to have many benefits compared to other exercises. Electrotherapy modalities are a popular treatment used by physiotherapists for a variety of purposes, such as muscle strengthening, endurance, spasticity management, pain control, circulation enhancement, and edema control. Kilohertz-frequency alternating currents were introduced in the pioneering work of Kots as a new form of neuromuscular electrical stimulation that was believed to solve some of the limitations of conventional electrical stimulation. Russian current is a medium-frequency alternating current that is delivered in bursts, with the carrier frequency ranging from 1000 to 10,000 Hz and any burst frequency being acceptable. Aussie currents are utilized in clinics at 1000 Hz, modulated in 50 Hz intervals with a pulse duration of 2 msec. Medium-frequency currents, particularly Russian and Aussie currents in isokinetic training, provide muscle strength contraction and endurance, increased blood circulation, and specific physiological effects. Considering the person’s health status, existing injuries, or other health problems, Russian and Aussie currents can be used effectively in isokinetic training at appropriate levels under the guidance of a physician and physiotherapist.
