“…Numerous studies have highlighted the bene cial impact of low-frequency NMES in improving muscle strength (13,14,23,28). However, only a limited number of researches have explored the effectiveness of medium-frequency (IF) NMES in improving muscle function in KOA.…”

“…It appears that NMES can effectively contribute to increasing muscle thickness, irrespective of the current frequency or the muscle type being investigated (13,23). However, the importance lies in the fact that medium-frequency interferential currents are more comfortable in inducing muscle contractions through electrical stimulation, making this method easier for patients to tolerate.…”

“…The position of electrodes was determined based on the alignment of QF bers, with particular emphasis on the Rectus Femoris and VMO. The proximal electrode was aligned with the Rectus Femoris, and the distal electrode was positioned over the VMO, with its lower edge placed 3 cm above and medial to the patella (23). The speci c treatment parameters used were as follows: Pulse Width: 600µs; Carrier Frequencies = 4,000-4,050; Beat (Sweep) Frequency = 50 Hz; Treatment duration: 15 minutes.…”

Background: One of the major contributors to disability in Knee osteoarthritis (KOA) patients is weakness in the Quadriceps Femoris muscle. Neuromuscular electrical stimulation (NMES) has been used in rehabilitation for patients suffering from muscle weakness. Thus, the purpose of the study was to assess the effectiveness of NMES and exercise therapy, for improving pain, muscle weakness and function among patients with KOA. Methods: A randomized controlled trial was conducted with 75 female patients diagnosed with KOA. Participants were divided into three intervention groups: NMES-only, exercise therapy (Exs) alone, and a combination of NMES and exercise (NMES+ Exs). All patients underwent 12 supervised treatment sessions, three times a week. Outcome measures included pain intensity measured by visual analog scale (VAS), knee flexion range of motion (FROM), thigh muscle girth (TG), thickness of the Vastus Medialis Oblique (VMO), timed up and go test (TUG), six-minute walk test (6MWT), and WOMAC scores. Statistical analyses (ANOVA and Kruskal-Wallis) methods were done to compare the amounts at the baseline, immediately after treatment and after 12 weeks. Results: The NMES group exhibited a significant reduction in pain at the 12-week follow-up compared to the other groups(p=0.022). The NMES+ Exs group showed better outcomes in terms of FROM, TG, and VMO thickness post-intervention (p <0.0001, p<0.004, p=0.003, respectively) and at the 12-week follow-up (p <0.0001, p <0.0001, p <0.0001, respectively). Additionally, NMES was superior in improving TUG and 6MWT post-intervention (p <0.0001, p=0.038, respectively) and during the follow-up assessments (p <0.0001, p=0.029, respectively). The NMES+ Exs group achieved better WOMAC stiffness scores at both post-intervention and follow-up evaluations (p <0.0001, p <0.0001, respectively). Furthermore, at the 12-week follow-up, NMES+ Exs group outperformed the others in WOMAC pain and function subscales (p=0.003, p=0.017, respectively), while the NMES group demonstrated better WOMAC total scores compared to the other groups (p=0.007). Conclusion: The combination of NMES and exercise seems to be an efficient approach for managing KOA, as it enhances knee flexion range and TG, increases VMO thickness, and improves WOMAC scores. On the other hand, NMES alone was found to be effective in improving the physical function of KOA patients. Trial registration: IRCT20101228005486N7 (06-02-2020).

This study was planned to compare the effectiveness of high voltage pulsed galvanic (HVPG) stimulation, Russian current and isometric exercise on quadriceps femoris (QF) isometric muscle strength in healthy young women. Methods: Forty-six healthy young women were included in the study. Before and after the training, the dominant side QF isometric muscle strength of participants was assessed with the isokinetic dynamometer. The peak torque and average torques of the participants were recorded after the test. The training was planned as HVPG current group (n=16), Russian current group (n=15) and isometric strengthening group (n=15). All treatments were performed under physiotherapist supervision for a total of 15 sessions for three days a week for five weeks. Results: The quadriceps isometric muscle strength was significantly increased in all groups in terms of peak torque and average torque values after training compared to pre-training values (p<0.05). No statistical difference was found between the groups when the peak torque and average torque delta values were compared (p>0.05). Conclusion: The highest rate of change belongs to the HVPG group in terms of increasing the QF isometric muscle strength. Therefore, we recommend using it in clinical practice.

“…In addition, ES is classified into three categories: low, medium, and high frequency. 4 Low frequency: 1 Hz to 1000 Hz (1 kHz) or pulses emitted per second-Medium frequency: 1 kHz to 10 kHz-High frequency: >10 KHz. 5 In general, low-frequency ES might induce less discomfort.…”

Electrotherapy or electrical stimulation (ES) is a part of clinical intervention in the rehabilitation field. With rehabilitation intervention, electrotherapy may be provided as a treatment for pain relief, strengthening, muscle education, wound recovery, or functional training. Although these interventions may not be considered as the primary therapy for patients, the advantages of the ease of operation, lower costs, and lower risks render ES to be applied frequently in clinics. There have also been emerging ES tools for brain modulation in the past decade. ES interventions are not only considered analgesics but also as an important assistive therapy for motor improvement in orthopedic and neurological rehabilitation. In addition, during the coronavirus disease pandemic, lockdowns and self-quarantine policies have led to the discontinuation of orthopedic and neurological rehabilitation interventions. Therefore, the feasibility and effectiveness of home-based electrotherapy may provide opportunities for the prevention of deterioration or extension of the original therapy. The most common at-home applications in previous studies showed positive effects on pain relief, functional ES, muscle establishment, and motor training. Currently, there is a lack of certain products for at-home brain modulation; however, transcranial direct current stimulation has shown the potential of future home-based rehabilitation due to its relatively small and simple design. We have organized the features and applications of ES tools and expect the future potential of remote therapy during the viral pandemic.
