“…The beat frequency sweep varied in pediatric studies from 80-120 Hz to 80-150 Hz. 9,33,35 To date, no serious adverse effects have been described. The only reported side effect is diarrhea, which was the trigger for investigating its application in constipation in the first place.…”

“…As a result, studies with larger groups of children, randomized to a longer, more frequent placebo or real stimulation (such as an hour a day daily for 3 to 6 months) were conducted. 35,36 Outcome measures over these different studies included soiling, defaecation frequency, urge to defaecate, quality of life and objective transit studies. Again there was a significant improvement in varying degrees to all, though quality of life indicators showed a modest, but statistically significant improvement as reported by the children, but not by their respective parents.…”

The concept of therapeutic percutaneous neuromodulation has, until recently, been limited by the ability to penetrate deeply enough to stimulate internal organs. By utilizing 2 medium frequency, slightly out of phase electrical currents passing diagonally through the abdomen, a third, low frequency current is created at the point of bisection. This interferential current appears to stimulate nerve fibers in the target organs and may have a therapeutic action. The aim of the study is to review the use of transcutaneous interferential electrical stimulation with a focus on its application in gastroenterology, particularly in motility disorders. Studies involving use of interferential current therapy were searched from Medline, PubMed, and Scopus databases, and articles pertaining to history, its application and all those treating abdominal and gastrointestinal disorders were retrieved. Seventeen studies were identified, 13 involved children only. Eleven of these were randomised controlled trials (3 in adults). Four trials were from the one center, where each paper reported on different outcomes such as soiling, defecation frequency, quality of life, and colon transit studies from the one pool of children. All studies found statistically significant improvement in symptom reduction. However, weaknesses in study design were apparent in some. In particular, finding an adequate placebo to interferential current therapy has been difficult. Interferential current therapy shows potential as a novel, non-pharmacological and economical means of treating gastrointestinal dysfunction such as constipation. More studies are needed particularly in the adult population. However, the design of a suitable placebo is challenging. Search MethodA search of Medline, PubMed, and Scopus databases for information on electrical interferential current and its application using search words such as "electrical interferential current," "transcutaneous," "therapeutics or uses," "mechanisms of action," and "gastrointestinal" was performed. Articles that were available in English were included. This review focuses on the use of transcutaneous interferential current therapy in the treatment of gastrointestinal symptoms. The Nature of Interferential Current TherapyInterferential current therapy has been used in a variety of settings including low back pain 11 and neurological disorders such as carpal tunnel syndrome. 12 More recently, interferential current therapy has been found to be effective in small studies in managing conditions such as fecal incontinence and constipation. It has the benefit of being completely non-invasive, cost effective and convenient, as it can be self-administered at home. 13Despite increased convenience to the patient, doctor and payer, the use of transcutaneously-delivered current can be problematic. To stimulate the nerve of interest, the current has to pass through the skin and surrounding muscle to reach its target. This causes resistance to flow, requiring the use of a higher current to achieve the desired resu...

AIMS: To assess accommodation phenomena characteristics (threshold, time and amplitude/intensity) during stimulation with interferential current, comparing male and female healthy adults. METHODS: A non randomized clinical trial with intentional sampling by gender included 30 healthy adult volunteers aged between 18 and 25 years, who were divided in two groups (15 in the Female Group and 15 in the Male Group) and received a tetrapolar interferential current for 20 minutes, close to L1 and L5 vertebrae. The subjects were instructed to refer an intense but comfortable paresthesia sensation and to report the moment it diminished (accommodation), requiring increasing of the current intensity. The first three events of accommodation (AV1, AV2 and AV3), including time and amplitude threshold, were analyzed. The differences from AV1 to AV2 (D1) and AV2 to AV3 (D2) were also considered. The number of accommodations for each subject during the 20 minutes experiment was identified. ANOVA and Student's t-test were used for analysis and the significance level was set at 5%. RESULTS: In the Male Group the mean time for accommodation was higher in AV3 compared to AV1 and AV2. In the Female Group the accommodation mean time was higher in AV3 in relation to AV2, and in AV2 in relation to AV1. No differences were found in the Male Group for D1 and D2, but in the Female Group, D2 was superior to D1. Women were accommodated more quickly than men in all three assessments, but the differences between one evaluation and another were constant considering both groups. Both groups showed similar current intensity behavior comparing the three evaluations within the same group. In the comparison between groups, women had lower mean values of intensity in the three evaluations. The Female Group had 7.5±1.5 accommodations, and the Male Group had 5.9±2.0 accommodations (p=0.0367) during the 20 minutes of the experiment. CONCLUSIONS: In this sample of healthy young adults, men required higher interferential current amplitude to obtain a comfortable paresthesia and took more time to have accommodations, while women had more accommodation episodes.KEY WORDS: electrical stimulation therapy; physical therapy modalities; sex characteristics; gender. RESUMOOBJETIVOS: Avaliar características dos fenômenos de acomodação (limiar, tempo e amplitude/intensidade) durante estimulação com corrente interferencial, comparando adultos saudáveis do gênero masculino e feminino. MÉTODOS: Um ensaio clínico não randomizado com amostragem intencional por gênero incluiu 30 voluntários adultos saudáveis com idade entre 18 e 25 anos, que foram divididos em dois grupos (15 no Grupo Feminino e 15 no Grupo Masculino) e receberam uma corrente interferencial tetrapolar por 20 minutos, na altura das vértebras L1 e L5. Os sujeitos foram instruídos a referir uma sensação de parestesia intensa mas confortável e relatar o momento em que ela diminuiu (acomodação), requerendo aumento da intensidade da corrente. Foram analisados os três primeiros fenômenos de acomodação (A...

“…Jorge et al 12 evidence that despite its short duration effect, the IFC is able to reduce the inflammatory pain. Tugay et al 13 mention that the IFC is efficient in the primary dysmenorrhea and studies prove the beneficial effects of IFC in the intestinal function of children with chronic constipation [14][15][16] . The study on interferential current is extremely important since despite being a technique widely used by physiotherapists, it does not present optimum parameters for stimulation; therefore, its therapeutic use is empiric, even to avoid accommodation.…”

Aims: To evaluate in how much time the interferential current (IFC) accommodation occurs, and how many times this accommodation happens in 10 minutes using different patterns of variations in the frequency of stimulation: ∆F null = 0; ∆F low = 30% and ∆F high = 70%. Materials and methods: crossover trial, with 15 volunteers, with mean age of 22.53 ± 0.91 years, of both genders. The patients were submitted to IFC for 10 minutes as bipolar with the electrodes longitudinally arranged on the vertebrae L1 and S1. The equipment parameters were: base frequency of 4000Hz, AMF 100 Hz, delivery ramp of ΔF 1:1, ΔF depending on the day and the subgroup, for 10 minutes. The accommodation threshold as well as how many times the current accommodated in the total time of stimulation were evaluated. Results: The time of the first accommodation and the number of accommodation evidenced no significant difference (p > 0.05). Conclusion: It was observed that there was no effect with the variation of the different ∆F analyzed.
