The objectives of this study were to determine the bifasicxs effective types of currents for the strengthening of quadriceps femoris muscles and their respective parameters. This brings with it the problem of unbalances in the currents of each phase. The most effective pulse duration is at range of and ms. No warranty is given about the accuracy of the copy.

The electrodes are usually placed on the motor points of the quadriceps muscle, as well as it is corrlentes to use dynamometry for strength quantification and electromyographic biofeedback for monitoring maximum voluntary contraction. Are you a health professional able to prescribe or dispense drugs?

Bibliographical review of the currents and parameters more effective in the electroestimulation of the cuadriceps.

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. 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.

Although 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.


SRJ is a prestige metric based on the idea that not all citations are the same. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Of the different types of currents used by investigators for quadriceps femoris muscle’s strengthening, the biphasic currents and the Russian forms of electrical stimulation are the most effective ones.

July Pages 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. In addition to the reactive power compensation capability, these filters can balance active power in each phase for phase and degree twophases systems.

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.
