RESUMO

Objective: To compare the segmental and extrasegmental hypoalgesic effects of TENS, IFC and Aussie current on pressure pain threshold (PPT) during and after stimulation in healthy subjects. The second objective was to compare the sensory comfort related to electrical stimulation. Material and Methods: 120 healthy subjects were randomized in TENS, IFC, Aussie current or placebo groups. The electrical stimulation was administered on the forearm. The PPT was measured on the forearm (segmental measure) and on the lower leg (extrasegmental measure) by an algometer at baseline, during and after stimulation of the forearm, and the sensory comfort in relation to electrical stimulation was measured with a visual analogue scale. Statistical analysis was performed using linear mixed models for PPT analysis and one-way ANOVA for sensory comfort analysis. Results: The TENS, IFC and Aussie current increased the segmental and extrasegmental PPTs during application of current compared to the placebo. The PPTs measures and sensory comfort were not significantly different between the TENS, IFC and Aussie current groups. Conclusions: Segmental and extrasegmental hypoalgesic effects may be produced using TENS, IFC or Aussie currents in healthy subjects. Furthermore, all of them presented a similar sensory comfort.

RESUMO

The aim of the present study was to evaluate the in vivo response of different wavelengths (red and near-infrared) of light-emitting diode (LED) on full-thickness skin grafts (FTSG) in rats. Thirty rats were randomly allocated into three experimental groups: control group (C); red LED treated group (R); and near-infrared LED group (NIR). Skin grafts were irradiated daily for ten consecutive days, starting immediately after the surgery using a red (630 nm) or near-infrared (850 nm) LED. The results showed that the red wavelength LED significantly enhanced the skin graft score in relation to the NIR group and increased transforming growth factor beta (TGF-ß) protein expression and density of collagen fibers compared with the other experimental groups. These results suggest that the red wavelength LED was efficient to improve the dermo-epidermal junction and modulate the expression proteins related to tissue repair.

RESUMO

Electrical stimulation is widely used for pelvic floor muscle dysfunctions (PFMDs), but studies are not always clear about the parameters used, jeopardizing their reproduction. As such, this study aimed to be a reference for researchers and clinicians when using electrical stimulation for PFMD. This report was designed by experts on electrophysical agents and PFMD who determined all basic parameters that should be described. The terms were selected from the Medical Subject Headings database of controlled vocabulary. An extensive process of systematic searching of databases was performed, after which experts met and discussed on the main findings, and a consensus was achieved. Electrical stimulation parameters were described, including the physiological meaning and clinical relevance of each parameter. Also, a description of patient and electrode positioning was added. A consensus-based guideline on how to report electrical stimulation parameters for PFMD treatment was developed to help both clinicians and researchers.

RESUMO

AIM: Transcutaneous electrical nerve stimulation (TENS) and cervical joint manipulation (CJM) are often used for pain treatment. METHODS: A total of 144 healthy subjects will be randomly allocated into four groups: active TENS and CJM, placebos TENS and CJM, placebo TENS and active CJM, active TENS and placebo CJM. TENS will be applied for 20 min followed by CJM. All subjects will be assessed before, during and after interventions, using a digital pressure algometer. DISCUSSION: This is the first study to assess the combined effects of TENS and CJM on pressure pain threshold in healthy individuals. It is possible that both methods combined can enhance the hypoalgesic effect because they activate different analgesic pathways. STUDY REGISTRATION:  NCT03531541 (ClinicalTrials.gov).

RESUMO

Objective: Technological advances have provided new alternatives to the analysis of skin flap viability in animal models; however, the interrater validity and reliability of these techniques have yet to be analyzed. The present study aimed to evaluate the interrater validity and reliability of three different methods: weight of paper template (WPT), paper template area (PTA), and photographic analysis. Approach: Sixteen male Wistar rats had their cranially based dorsal skin flap elevated. On the seventh postoperative day, the viable tissue area and the necrotic area of the skin flap were recorded using the paper template method and photo image. The evaluation of the percentage of viable tissue was performed using three methods, simultaneously and independently by two raters. The analysis of interrater reliability and viability was performed using the intraclass correlation coefficient and Bland Altman Plot Analysis was used to visualize the presence or absence of systematic bias in the evaluations of data validity. Results: The results showed that interrater reliability for WPT, measurement of PTA, and photographic analysis were 0.995, 0.990, and 0.982, respectively. For data validity, a correlation >0.90 was observed for all comparisons made between the three methods. In addition, Bland Altman Plot Analysis showed agreement between the comparisons of the methods and the presence of systematic bias was not observed. Innovation: Digital methods are an excellent choice for assessing skin flap viability; moreover, they make data use and storage easier. Conclusion: Independently from the method used, the interrater reliability and validity proved to be excellent for the analysis of skin flaps' viability.

RESUMO

Marjolin's ulcers (MU) are skin malignancies that form over burn injuries. These very aggressive ulcers can result in functional and wound healing impairment, and require a well thought out treatment plan. Physiotherapy offers resources to help promote recovery of these patients, as described in this case report, in which the patient with a history of burn in the lower limbs evolved to malignancy 32 years later. This patient underwent tumor resection of the left foot, with recurrence and lymphadenectomy. Physical therapy included the application of high-frequency generator (HFG) for wound healing and exercises for functional recovery. The treatment lasted for many months and resulted in the improvement of the surgical wound areas, pain, swelling, sensitivity, strength muscle, and gait. It was observed that the use of HFG can be a tool in the tissue repair of surgical wound after the resection of MU; however, further studies need to be carried out to suit parameters and ensure safety of cancer patients.

RESUMO

Background and objectives: Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. Subjects and methods: Twenty healthy women aged 20-40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. Results: Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group (P<0.05) and in the buttocks (P<0.05) and the posterior thigh areas (P<0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 (P<0.05) and G2 (P<0.05), and in posterior thigh areas, G1 (P<0.05) and G2 (P<0.05). Optimal improvement of skin firmness (G1, P<0.0001; G2, P=0.0034) in the treated areas was observed in both groups. Conclusion: We conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results.

RESUMO

BACKGROUND: Transcutaneous electrical nerve stimulation and interferential current have been widely used in clinical practice. However, a systematic review comparing their effects on pain relief has not yet been performed. OBJECTIVES: To investigate the effects of transcutaneous electrical nerve stimulation and interferential current on acute and chronic pain. METHODS: We use Pubmed, Embase, LILACS, PEDro and Cochrane Central Register of Controlled Trials as data sources. Two independent reviewers that selected studies according to inclusion criteria, extracted information of interest and verified the methodological quality of the studies made study selection. The studies were selected if transcutaneous electrical nerve stimulation and interferential current were used as treatment and they had pain as the main outcome, as evaluated by a visual analog scale. Secondary outcomes were the Western Ontario Macmaster and Rolland Morris Disability questionnaires, which were added after data extraction. RESULTS: Eight studies with a pooled sample of 825 patients were included. The methodological quality of the selected studies was moderate, with an average of six on a 0-10 scale (PEDro). In general, both transcutaneous electrical nerve stimulation and interferential current improved pain and functional outcomes without a statistical difference between them. CONCLUSION: Transcutaneous electrical nerve stimulation and interferential current have similar effects on pain outcome The low number of studies included in this meta-analysis indicates that new clinical trials are needed.

RESUMO

Abstract Introduction: Transcutaneous electrical nerve stimulation (TENS) can alter the local temperature, increase skin blood flow and induce the release of vasodilator neuropeptides and growth factors. These changes may be related to the effects of TENS on the tissue repair process. Objective: To assess the effect of high- and low-frequency TENS on angiogenesis and the contraction of acute excisional wounds in rat skin. Methods: Fifty-four young adult male EPM1-Wistar rats were used in the study. An excisional wound was performed on the back of each animal using an 8mm punch. The animals were randomly assigned to three groups: the High-frequency Group (HG: 80 Hz), Low-frequency Group (LG: 5 Hz), and Sham Group (SG: TENS turned off). TENS was delivered on three days consecutives. Pulse duration and current intensity were 200 µs and 15 mA. The length of each TENS session was 60 minutes. Microscopic and macroscopic assessments were performed on 3, 7 and 14 postoperative (PO) days. Hematoxylin-eosin staining was utilized to quantify the neoformed blood vessels. Photographs were taken to determine the percentage of wound contraction. After assessment, the animals were painlessly sacrificed. Results: There were increases in angiogenesis in the HG on the 3 PO day, and in the LG on the 14 PO day. No significant differences in wound contraction were found between the groups on the different PO days. Conclusion: High frequency TENS improved angiogenesis, and neither frequency of TENS had any influence on the contraction of acute excisional wounds in rat skin.


Resumo Introdução: A TENS pode promover alteração da temperatura local, aumento do fluxo sanguíneo cutâneo, liberação de neuropeptídeos vasodilatadores e de fatores de crescimento. Tais eventos podem estar relacionados aos efeitos da TENS no processo de reparo tecidual. Objetivo: Avaliar o efeito da TENS de alta e de baixa frequências na angiogênese e na contração da ferida excisional aguda em pele de ratos. Materiais e Métodos: Foram utilizados 54 ratos (Wistar-EPM1), machos e adultos jovens. Realizou-se uma ferida excisional na região dorsal do animal com um punch medindo 8 milímetros. Os animais foram randomizados em três grupos: Grupo Alta frequência (HG:80 Hz), Grupo Baixa frequência (LG:5 Hz) e Grupo Simulado (SG, TENS desligada). A TENS foi aplicada por 3 dias consecutivos. A duração do pulso e intensidade da corrente foram 200 µs e 15 mA. O tempo de cada aplicação foi de 60 minutos. As análises microscópicas e macroscópicas foram feitas nos POI, 3, 7 e 14 dias de pós-operatório (PO). Utilizou-se a hematoxilina-eosina para quantificação dos vasos neoformados. Foram feitas imagens fotográficas para determinação da porcentagem de contração da ferida. Após as avaliações, os animais foram sacrificados. Resultados: Observou-se aumento na quantidade de vasos sanguíneos no HG, aos 3 dias de PO; e no LG, aos 14 dias de PO. Não houve alterações na contração da ferida entre os grupos. Conclusão: A TENS de alta frequência estimulou a angiogênese e ambas as frequências não influenciaram na contração da ferida excisional aguda em pele de ratos.

RESUMO

OBJECTIVE: To determine whether interferential current (IFC) before Pilates exercises is more effective than placebo in patients with chronic nonspecific low back pain. DESIGN: Two-arm randomized controlled trial, with a blinded assessor, and 6 months follow-up. SETTING: Clinic of a school of physical therapy. PARTICIPANTS: The random sample consisted of patients (N=148) of both sexes, with age between 18 and 80 years and chronic nonspecific low back pain. In addition, participants were recruited by disclosure of the treatment in the media. INTERVENTIONS: Patients were allocated into 2 groups: active IFC + Pilates or placebo IFC + Pilates. In the first 2 weeks, patients were treated for 30 minutes with active or placebo IFC. In the following 4 weeks, 40 minutes of Pilates exercises were added after the application of the active or placebo IFC. A total of 18 sessions were offered during 6 weeks. MAIN OUTCOME MEASURES: The primary outcome measures were pain intensity, pressure pain threshold, and disability measured at 6 weeks after randomization. RESULTS: No significant differences were found between the groups for pain (0.1 points; 95% confidence interval, -0.9 to 1.0 points), pressure pain threshold (25.3kPa; 95% confidence interval, -4.4 to 55.0kPa), and disability (0.4 points; 95% confidence interval, -1.3 to 2.2). However, there was a significant difference between baseline and 6-week and 6-month follow-ups in the intragroup analysis for all outcomes (P<.05), except pressure pain threshold in the placebo IFC + Pilates group. CONCLUSIONS: These findings suggest that active IFC before Pilates exercise is not more effective than placebo IFC with respect to the outcomes assessed in patients with chronic nonspecific low back pain.

RESUMO

Quantitative sensory testing is widely used in human research to investigate the state of the peripheral and central nervous system contributions in pain processing. It is a valuable tool to help identify central sensitization and may be important in the treatment of low back pain. The aim of this study was to evaluate changes in local and segmental hypersensitivity and endogenous pain inhibition in people with chronic nonspecific low back pain. Thirty patients with chronic low back pain and thirty healthy subjects were studied. Pressure pain thresholds (PPTs) were measured from the lumbar region and over the tibialis anterior muscle (TA). A cold pressor test was used to assess the activation of conditioned pain modulation (CPM), and PPTs in the lumbar region were recorded 30 s after immersion of participant's foot in a bucket with cold water. People with chronic low back pain have significantly lower PPT than controls at both the lumbar region [89.5 kPa (mean difference) 95 % CI 40.9-131.1 kPa] and TA [59.45 kPa (mean difference) 95 % CI 13.49-105.42 kPa]. During CPM, people with chronic low back pain have significantly lower PPT than controls in lumbar region [118.6 kPa (mean difference) 95 % CI 77.9-159.2 kPa]. Women had significantly lower PPTs than men in both lumbar region [101.7 kPa (mean difference) 95 % CI 37.9-165.7 kPa] and over the TA [189.7 kPa (mean difference) 95 % CI 14.2-145.2 kPa]. There was no significant difference in PPTs in men between healthy controls and those with low back pain, suggesting the significant differences are mediated primarily by difference between women.

RESUMO

BACKGROUND: Liposuction is a common cosmetic surgical procedure, which requires analgesia for postoperative pain. Transcutaneous electrical nerve stimulation (TENS) has been used for postoperative pain relief; however, there is no evidence of its effectiveness in liposuction patients and this is the focus of this paper. METHODS: A prospective, randomized, double-blind, controlled trial was conducted with 42 adult patients who underwent liposuction. Patients were randomly allocated to either the TENS group (active TENS) or control group (sham TENS). All patients received morphine (0.1 mg/kg) and dipyrone 1 g immediately after surgery; TENS was delivered 2 h later. The primary outcome was pain intensity. Secondary outcomes were analgesic requirement, number and types of adverse effects of TENS, quality of pain, treatment success, and patient satisfaction. Postoperative pain was measured using a visual analog scale (VAS) and the Brazilian version of the McGill Pain Questionnaire (Br-MPQ). RESULTS: Patients in the TENS group reported significantly lower pain intensity (P < 0.001, effect size = 0.92) compared with those in the control group. TENS significantly decreased the consumption of analgesics in the postoperative period (P < 0.001). No withdrawals or adverse effects were observed in the TENS group, but 33.3% of patients in the control group reported drowsiness and nausea. About 95 and 38% of patients in the TENS and control groups, respectively, were satisfied with the analgesic treatment. CONCLUSION: The results indicate that TENS is effective as an adjunct to analgesics for pain relief after liposuction.

RESUMO

BACKGROUND: Chronic low back pain is one of the four most common diseases in the world with great socioeconomic impact. Supervised exercise therapy is one of the treatments suggested for this condition; however, the recommendation on the best type of exercise is still unclear. The Pilates method of exercise is effective in reducing pain and disability in these patients, as well as the analgesia promoted by interferential current. Currently, the literature lacks information on the efficacy of the association of these two techniques in the short- and medium-term than performing one of the techniques isolated. The objective of this study will be to evaluate the efficacy of adding interferential current to the Pilates method exercises for the treatment of patients with chronic nonspecific low back pain in the short- and medium-term. METHODS/DESIGN: This study will be a randomized controlled trial with two arms and blinded evaluator, conducted at an outpatient Physical Therapy Department in Brazil. Patients with nonspecific chronic low back pain and pain equal to or greater than 3 in the Pain Numerical Rating Scale (0/10) will be randomly assigned to one of two groups: Group with active interferential current + Pilates (n = 74) will be submitted to the active interferential current associated to the modified Pilates exercises, and Group with sham interferential current + Pilates (n = 74) will be submitted to the sham interferential current associated with the modified Pilates exercises during 18 sessions. The outcomes pain intensity, pressure pain threshold, general and specific disability, global perceived effect and kinesiophobia will be evaluated by a blinded assessor at baseline, six weeks and six months after randomization. DISCUSSION: Because of the study design, blinding of the participants and the therapists involved in the study will not be possible. The results of this study could contribute to the process of clinical decision- making for the improvement of pain and disability in participants with nonspecific chronic low back pain. TRIAL REGISTRATION: ClinicalTrials.gov NCT01919268.

RESUMO

Significance: Angiogenesis is an important phenomenon involved in the healing of chronic wounds, and it is mainly mediated by the release of vascular endothelial growth factor (VEGF) from endothelial cells. Electrical stimulation (ES) is a well-documented treatment used to assist the healing of chronic wounds. Due to the importance of VEGF in the healing process, and the need to know the mechanisms of action of ES involved in the process, this report aimed to determine by a literature review whether the VEGF release occurs following ES in human subjects. Recent Advances: The findings of this literature review suggest that ES releases VEGF, and this effect may be responsible for promoting angiogenesis after ES. Critical Issues: Despite the findings of this literature review on the release of VEGF by ES on wound healing are promising, a large number of studies are needed to confirm such effects. Future Directions: Further studies should be conducted to identify the best parameters and treatment schedule of ES to be used for the VEGF release.

RESUMO

OBJECTIVE: To compare the immediate effects of electroacupuncture and manual acupuncture on pain, mobility and muscle strength in patients with knee osteoarthritis. METHODS: Sixty patients with knee osteoarthritis, with a pain intensity of ≥2 on the pain Numerical Rating Scale, were included. The patients were randomised into two groups: manual acupuncture and electroacupuncture. Pain intensity, degree of dysfunction (Timed Up and Go (TUG) test), maximal voluntary isometric contraction and pressure pain threshold were assessed before and after a single session of manual acupuncture or electroacupuncture treatments. RESULTS: Both groups showed a significant reduction in pain intensity (p<0.001) and time to run the TUG test after the acupuncture treatment (p=0.005 for the manual acupuncture group and p=0.002 for the electroacupuncture group). There were no differences between the groups regarding pain intensity (p=0.25), TUG test (p=0.70), maximum voluntary isometric contraction (p=0.43) or pressure pain threshold (p=0.27). CONCLUSIONS: This study found no difference between the immediate effects of a single session of manual acupuncture and electroacupuncture on pain, muscle strength and mobility in patients with knee osteoarthritis.

RESUMO

STUDY DESIGN: Repeated-measures, within-subject crossover trial. OBJECTIVES: The primary objective was to assess the effect of the burst-duty-cycle parameters of medium-frequency alternating current on the maximum electrically induced torque of the quadriceps femoris. The secondary objectives were to evaluate the amount of discomfort tolerated and the maximum current amplitude delivered for each electrical-stimulation condition. BACKGROUND: Neuromuscular electrical stimulation used for muscle strengthening can improve functional performance. However, the electrical-stimulation parameters to achieve optimal outcomes are still unknown. Previous studies have demonstrated that the characteristics of the burst duty cycle of medium-frequency alternating current influence torque-generation levels and perception of sensory discomfort. METHODS: The maximum electrically induced torque was assessed with a medium-frequency alternating current, with a carrier frequency of 2500 Hz and a modulated frequency of 50 Hz. The current amplitude was gradually increased to the point of the participant's maximum tolerance level. The testing sequence for the 3 burst duty cycles (20%, 35%, and 50%) was performed in a randomized order. RESULTS: Electrical stimulation using a 20% burst duty cycle produced an electrically induced torque greater than the 35% (P = .01) and 50% (P<.01) burst duty cycles, with no difference between the 35% and 50% burst duty cycles (P = .46). There was no difference in the amount of sensory discomfort produced by the 3 durations of burst duty cycles (P = .34). There was also no difference between the 3 conditions for the maximum current amplitude tolerated (P = .62). CONCLUSION: The burst duty cycle of 20% of medium-frequency alternating current, compared to burst duty cycles of 35% and 50%, produced higher peak torque of the quadriceps femoris in professional soccer players. There was no difference in discomfort produced and current amplitude tolerated between the different burst-duty-cycle conditions.
