Of the different types of currents used by investigators for quadriceps bjfasicas muscle’s strengthening, the biphasic currents and the Russian forms of electrical stimulation are the most effective ones.

This abstract may be abridged. The present work proposes the use of two inverter topologies acting as active two-phases power filters.

Electrical stimulation; Muscle strength; Quadriceps. However, users may print, download, or email articles for individual use. Biphasic currents and the Russian forms of electrical stimulation are the most effective currents for quadriceps femoris muscle strengthening but, for them to be effective, they most generated the strongest muscle contraction with the lowest fatigue and discomfort possible.

This brings with it the problem of unbalances in the currents of each phase. The electrodes are usually placed on the motor points of the quadriceps muscle, as well as it is common to use dynamometry for strength quantification and electromyographic biofeedback for monitoring maximum voluntary contraction.

vifasicas However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution. From Monday to Friday from 9 a. In addition to the reactive power compensation capability, these filters can balance active power in each phase for phase and degree twophases systems. The inclusion of high consumption electric loads such as induction stove and electric heaters has made it necessary to install a second phase in many homes.


In reference to pulse frequency, it seems that for biphasic currents and Russian forms of electrical stimulation a range of 40 to 70 Hz and 2, Hz, respectively, are the most effective ones for greater force production. It is well known that electrical stimulation mantains and increases the quadriceps femoris muscle’s strength and allows the prevention of muscle atrophy and increases the muscle’s resistance and work capacity; the only problem is that there isn’t any review in this matter that determines which types of currents and parameters are preferential in muscle strengthening.

Previous article Next article. It is also reported the use of a 1: These are the options to access the full texts of the publication Fisioterapia.

Corruentes electrical stimulation is an effective strengthening method, there is still controversy about the combination of this method with others that can allow more strength production; despite this reality, literature shows that electrical stimulation alternated with voluntary muscle contractions can in fact produce more muscle strength.
