“…On the contrary, many studies have demonstrated no difference in evoked torque between KAC and PC, 5,6,[20][21][22]25,27,28 whereas other studies found that PC was more effective than KAC. 5,7,8,26,[29][30][31] We only found 1 study with results comparable to ours. In that study, it was concluded that Russian current elicited lower mean torque of wrist extensors than those elicited by Aussie current and monophasic PC, with a pulse frequency equal to the 50-HZ burst.…”

“…Punctual stimulation was applied near the middle portion of the muscle belly of the quadriceps, and the motor point was determined as the point where the strongest contraction of the quadriceps as a whole was obtained. This was confirmed by visual inspection of the contraction of the muscle belly and by the confirmation of the patient that this point corresponded to the site where the stimulation was felt with greater intensity .…”

This study aimed to evaluate the effects of neuromuscular electrical stimulation (NMES) on muscle strength and architecture, functional capacity, and endothelial function in patients with chronic kidney failure (CKF) on hemodialysis (HD). Twenty-one patients with CKF on HD were randomized into a control group (CG; n = 10) and neuromuscular electrical stimulation group (NMESG; n = 11) who received NMES in the quadriceps muscle for 8 weeks, 3 times/week (20-34 min) during HD sessions. The muscle strength of the lower limbs was evaluated by dynamometry and sit-and-stand test (SST); muscle architecture through ultrasonography; functional capacity by the distance covered in a 6-min walk test and the endothelial function by flow-mediated dilatation technique of the brachial artery. There was an increase in the strength of the lower limbs in the NMESG compared to the CG (dynamometry: 43.28 ± 16.94 vs. 35.84 ± 16.89, P = 0.006; SST: 16.10 ± 6.51 vs. 12.50 ± 4.7, P = 0.029). There was a significant reduction in pennation angles of the right vastus lateralis (RVL) and left vastus lateralis (LVL) in the CG when compared to the NMESG (RVL: 11.93 [10.70-15.11] vs. 13.57 [11.81-15.96], P = 0.039; LVL: 11.62 [9.00-14.20] vs. 15.52 [12.86-20.02], P = 0.042). There was no change in functional capacity and in the endothelial function for CG and NMESG, respectively. In conclusion, NMES increases muscle strength and has a protective effect against muscle atrophy of the lower limbs of patients with chronic kidney failure on HD.

“…Similarly, Yaz et al 32 have found that both Russian current and low frequency current were capable to increase the maximum extensor peak torque of quadriceps muscles, even that the low frequency current was more effective than Russian current. Moreover, the recruitment order of electrical stimulation is reversed relative to volitional exercise.…”

Abstract:Isokinetic training and Russian current stimulation have been advertised to increase muscle strength. So, the purpose of this study was to compare between unilateral isokinetic concentric training and Russian current stimulation on the quadriceps strength of ipsilateral and contralateral limbs. Sixty healthy male subjects were randomly assigned into 3 equal groups; Isokinetic group; received isokinetic concentric training. Russian group; received Russian current stimulation, and control group: did not receive any training program. Isokinetic and Russian groups trained for 4 weeks, 3 session/week on the dominant quadriceps femoris muscle. Biodex Multi-joint System 3, Biodex, Shirley, NY, used to measure the isokinetic concentric peak torque/body weight before and after 4 weeks training for all groups at angular velocity 30°/s. For contralateral and ipsilateral quadriceps strength there was significant increase in the quadriceps strength of isokinetic and Russain group (p= 0.000). However, there was no significant increase in the quadriceps strength of control group (p= 0.214, 0.061) respectively. There was no significant difference between isokinetic and Russian group for the value of increasing of the quadriceps strength (p= 0.391, 0.579) respectively. The percent of improvement of ipsilateral side was significantly higher than the improvement of contralateral side for isokinetic and Russian group (p= 0.004, 0.006) respectively. So, Isokinetic training and Russian current stimulation have equal level of effectiveness in improving the concentric strength of the contralateral and ipsilateral quadriceps muscle. In spite of, the improvement of ipsilateral side was higher than that of the contralateral side.
