Effects of therapeutic ultrasound and paraffin with or without vacuum massage on biomechanical properties of grafted skin after burn: a randomized controlled trial.

OBJECTIVE: This study aimed to compare the effects of therapeutic ultrasound and paraffin with or without vacuum massage on the biomechanical properties of grafted skin after a burn. METHODS: A total of 44 patients with deep second- and third-degree burns, with a mean age of 35.89 (±11.53) years, who visited the Hospital Burn Unity, were included in the study. The therapeutic interventions were randomly defined by drawing lots, with a crossover design (crossover), and a minimum interval of 7 days (washout) between interventions. Skin biomechanical parameters such as distensibility (R0) and viscoelasticity (R6) were noninvasively evaluated by Cutometer before and after 0, 10, 20, and 30 min of intervention with therapeutic ultrasound and paraffin alone, as well as associated with negative pressure therapy of the skin (vacuum therapy). In this study, all groups showed increased distensibility (R0) in the period immediately after the application of the resources and a progressive reduction in the effects in the consecutive tests. Participants with skin grafts showed a decrease in viscoelasticity (R6) in all groups, except therapeutic paraffin and therapeutic ultrasound and vacuum massage. CONCLUSION: The biomechanical properties of grafted skin after a burn are altered after therapeutic intervention with ultrasound alone or associated with vacuum massage, such as intervention with paraffin associated with vacuum massage, for both parameters evaluated, skin distensibility (R0) and skin viscoelasticity (R6). However, the same did not occur for the intervention with isolated paraffin. There was no significant difference between the interventions therapeutic ultrasound and therapeutic paraffin.

Correlation between the range of motion of the tibiotarsal joint and blood circulation in the lower limbs in diabetic individuals.

OBJECTIVE: The aim of this study was to evaluate the relationship between the range of motion and lower-limb hemodynamic indices in the tibiotarsal joint of individuals with diabetic neuropathy. METHODS: Twenty volunteers of both sexes, with a mean age of 61.45±7.05 years, were diagnosed with type 2 diabetes mellitus and diabetic peripheral neuropathy. Arterial blood flow was assessed using Doppler ultrasound, and the variables such as average velocity, pulsatility index, and resistivity index were also evaluated. A range of dorsiflexion and plantar flexion joint movements were assessed using digital goniometry before and after exercise. Data distribution was assessed using the Shapiro-Wilk test, followed by Pearson's correlation for normal data and Spearman's correlation for non-normal data, in order to verify the association between variables. RESULTS: A moderate correlation was found between dorsiflexion and pulse rate on two occasions before (rs=0.497) and after initial evaluation (rs=0.511). A low correlation was found between plantar flexion and mean velocity (rs=-0.357), pulsatility index (rs=0.439), and resistivity index (rs=0.328); dorsiflexion and mean velocity (rs=0.374), pulse rate (rs=0.332), and resistance index (rs=0.327) before evaluation, and peak (rs=0.346) was observed after the evaluation of blood circulation. CONCLUSION: There is a correlation between the range of motion of the tibiotarsal joint and the blood circulation of diabetics, ranging from moderate to poor for the different variables evaluated.

Intra- and inter-examiner reliability of digital images of skin donor areas in burns.

OBJECTIVE: The main objective of this study was to evaluate intra- and inter-rater reliability in the analysis of digital images of donor areas for skin in burn patients using the CaPAS plugin in the ImageJ®. METHODS: Donor sites were reviewed by two independent reviewers in duplicate. The capture of images was standardized on the same device and distance (with a millimeter ruler), without a flash. The evaluators were trained to capture the images and use the plugin. RESULTS: We selected 70 images from donor areas, from men and women between 18 and 60 years old. In the analysis of intra-examiner reliability, eight of the nine variables exhibited excellent reliability (0.985-0.998) and one (entropy) exhibited good reliability (0.525). The same was true for the inter-examiner analysis: excellent reliability for eight variables (0.824-0.993) and good reliability for entropy (0.501). CONCLUSIONS: The CaPAS plugin has proven to be a reliable tool for use in research in skin donor areas in burns, as demonstrated by its excellent intra- and inter-examiner reliability values. This is a pioneering study in the quantitative assessment of skin donor areas in burn patients using the CaPAS plugin.

Psychometric properties of the Brazilian short-version of the Northwick Park Neck Pain Questionnaire.

OBJECTIVE: To translate, cross-culturally adapt and assess measurement properties of the translated version of the Northwick Park Neck Pain Questionnaire into Brazilian Portuguese. DESIGN: Cross-sectional study. SETTINGS: University healthcare facility and online. PARTICIPANTS: People with chronic neck pain (n = 178). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants answered the translated version of Northwick Park Neck Pain Questionnaire, the Neck Disability Index, the Numerical Rating Scale for pain, the Tampa Scale for Kinesiophobia and the Pain Catastrophizing Scale. Seven to ten days after that, a subset of 84 participants answered the Northwick Park Neck Pain Questionnaire again. The structural (exploratory and confirmatory factor analyses) and construct validities, internal consistency, reliability and concordance were assessed. Level of significance was set at 5%. RESULTS: Participants' (35.6 ± 13.5 years old) with symptoms duration of 54.4 ± 60.4 months scored 25.5 ± 14.0 on the Brazilian Northwick Park Neck Pain Questionnaire and 11.9 ± 5.8 on the Neck Disability Index. The structural analysis showed that the short version of the Northwick Park Neck Pain Questionnaire has an adequate structure to measure disability due to neck pain. Correlations with other questionnaires were between 0.268 and 0.678, Cronbach's alfa was 0.76, intraclass correlation coefficient was 0.96, standard error of measurement was 2.74 and minimal detectable change was 7.60. CONCLUSION: The short version of the Northwick Park Neck Pain Questionnaire is valid and reliable to be used in patients with chronic neck pain, as it presented adequate measurement properties of structural and construct validity, reliability and concordance.

Effects of Complex Physical Therapy and Multimodal Approaches on Lymphedema Secondary to Breast Cancer: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: What are the immediate, short-term, and long-term effects of complex physical therapy and multimodal approaches on lymphedema secondary to breast cancer? DATA SOURCES: Four electronic databases (MEDLINE, Embase, Cochrane Library, Physiotherapy Evidence Database) were searched from inception up to August 2020. STUDY SELECTION: Randomized controlled trials comparing complex physical therapy and multimodal approaches to the conservative treatment of lymphedema secondary to breast cancer. DATA EXTRACTION: Two independent researchers performed data extraction and assessed the risk of bias, respectively, using the predefined form and Cochrane Collaboration of Risk of Bias. The determination of evidence quality was carried out using the Grading of Recommendations Assessment, Development, and Evaluation tools. DATA SYNTHESIS: Fourteen studies were identified for the systematic review and 11 studies for the meta-analysis with standardized mean difference (SMD), 95% CI, and random-effect model. The common outcomes involved total volume, pain, and physical function of the upper limb. Complex physical therapy has shown a favorable tendency to control outcomes in the short- and long-term. The meta-analysis indicated a small effect for volume reduction (SMD, -0.18; 95% confidence interval [CI], -0.35 to 0.00) and a moderate effect for short-term pain reduction (SMD, -0.61; 95% CI, -1.19 to -0.02). CONCLUSIONS: High-quality evidence suggests a more significant effect of complex physical therapy on multimodal approaches to the control of the upper limb total volume, substantiating the absence of changes in the current clinical practice in the management of lymphedema secondary to breast cancer. Future research should aim to identify concrete effect of therapeutic modalities in the immediate-, short-, and long-term.

However, the same did not occur for the intervention with isolated paraffin. There was no significant difference between the interventions therapeutic ultrasound and therapeutic paraffin.

Influence of age and lymphedema on the postural balance of women undergoing breast cancer treatment.

INTRODUCTION: Breast cancer affects women of different ages, and comorbidities resulting from treatment can affect postural stability. The study aimed to evaluate the influence of age and lymphedema on the postural balance of women undergoing breast cancer treatment. METHODS: The study included 77 women undergoing breast cancer treatment, divided into different groups: 37 young adult women divided into 17 with lymphedema (GYL) and 20 young adults without lymphedema (GY); 40 elderly women, 20 elderly women with lymphedema (GEL) and 20 elderly women without lymphedema (GE). Mini Balance Evaluation Systems Test (Mini BESTest) and Falls Efficacy Scale - International (FES-I) were used. RESULTS: Mini BESTest and FES-I between the groups showed that GE and GEL had a significant difference to GY. Mini BESTest Total and Time Up and Go TUG-Double Task showed that GE has a significant difference to GYL, with GE and GEL having lower scores. Moderate negative correlation in the GEL between FES-I and Mini BESTest. In the age correlation between the Mini BESTest, FES-I, TUG, and double task TUG, a moderate positive correlation was observed for TUG. GEL showed a moderate positive correlation for FES-I and double-task TUG, strong for TUG, and moderate negative correlation with Mini BESTest. Correlation of the volume difference between the limb affected and not affected by lymphedema and the FES-I, Mini BESTest, TUG, and TUG double task, GYL showed moderate negative correlation for TUG. CONCLUSION: Age and lymphedema influenced the dynamic postural balance of women undergoing breast cancer treatment.

Body postural realignment in the first 2 months after orthognathic surgery.

INTRODUCTION: This study aimed to assess the static posture in patients with Angle Class II and III malocclusions in the first 2 months after orthognathic surgery. METHODS: This was a longitudinal observational study. Eligible participants were adult patients who had an indication of orthognathic surgery (bilateral sagittal split osteotomy of the maxilla and/or mandible, can be associated or not with genioplasty). Thirty-five patients were evaluated from the orthognathic surgery group (OSG) and control group (CG). Measurements in OSG were performed at 3 time points: preoperative orthognathic surgery (P0), first postoperative month (P1), and second postoperative month (P2). Static posture was evaluated using the PostureScreen Mobile (PostureCo Inc, Trinity, Fla) application in 4 views. RESULTS: Patients with Angle Class II malocclusion in the OSG evidenced a tendency to a left hip translation at P1 with a significant difference at P2 in the anterior view (P = 0.052). In the right lateral view, patients with Angle Class II malocclusion in the OSG at P1 presented an accentuated anterior shoulder translation when compared with CG (P <0.001). At P1, patients with Angle Class II malocclusion in the OSG showed a significant anterior knee translation compared with the CG and OSG at P0 and P2 (P <0.001 for all). Patients in the OSG with Angle Class III malocclusion presented an average posterior head translation in the right lateral view at P1 when compared with those in the CG and OSG at P0, who presented an anterior translation (P = 0.0008). CONCLUSIONS: These findings suggest a realignment of static posture in the first 2 months after orthognathic surgery.

Immediate Effect of Manual Therapy on Tibiotarsal Joint Mobility and Static Balance in Individuals With Diabetes.

Objectives: The objective of this study was to evaluate the immediate effect of manual therapy on ankle joint mobility and static balance in patients with diabetes. Methods: Forty patients, at a mean age of 59.35 ± 7.85, with type 2 diabetes mellitus and neurologic symptoms according to a Neuropathy Symptom Score protocol with amplitude, were included. The patients were divided into 2 groups: sham group and intervention group, which underwent manual manipulation intervention and 7-day follow-up. Joint range-of-motion analysis was performed using digital goniometry and static discharge of weights assessed by computerized baropodometry with open and closed eyes. The Shapiro-Wilk normality test was used to analyze the distribution. The data showed normal distribution, so the analysis of variance tests followed by Tukey's tests were used. SAS statistical software was used and the significance level was 5%. Results: The results of the intervention group showed an increase in the variable ankle goniometry over time compared to the sham group. The dorsiflexion movement on the right side obtained major gains over time; in addition, plantar flexion increased. Conclusion: Based on the participants evaluated in this study, manual therapy increased the ankle joint amplitude and improved the static balance in individuals with diabetes.

Proprioceptive neuromuscular facilitation in the functionality and lymphatic circulation of the upper limb of women undergoing breast cancer treatment.

BACKGROUND: With the increase in survival of women treated for breast cancer, it is necessary to evaluate the effect of therapeutic resources on co-morbidities resulting from the surgical treatment of the disease. The aim of this study was to evaluate the effects of proprioceptive neuromuscular facilitation on the functionality and lymphatic circulation of the upper limb involved in the treatment of breast cancer. METHODS: The study was conducted according to randomized clinical trial design. Thirty-two women at a mean age of 52.20 (±8.32) years, submitted to breast cancer treatment, divided into two groups, control - women submitted to standard breast cancer treatment, and treated group, composed of women who underwent breast cancer treatment and rehabilitation with the proprioceptive neuromuscular facilitation technique. Palmar grip strength with dynamometer and shoulder range of motion with goniometer were evaluated. Lymphatic circulation analysis was performed in a computerized scintillation chamber, before and after therapeutic intervention. FINDINGS: In the results obtained, a significant increase (p < 0.05) of palmar grip strength was observed, a significant increase in range of motion of flexion (p < 0.001), extension (p < 0.0012), abduction (p < 0.0001), external rotation (p < 0.0001), internal rotation (p < 0.0001), and not significant for lymphatic flow (p > 0.05). INTERPRETATION: The results obtained in this study allow us to conclude that proprioceptive neuromuscular facilitation favors an increase in muscle strength, range of motion, but not in lymphatic flow, in women undergoing surgical treatment for breast cancer.

Analysis of low-level laser transmission at wavelengths 660, 830 and 904 nm in biological tissue samples.

BACKGROUND: In recent decades, low-level laser therapy (LLLT) has occupied a prominent position and has been studied in various fields of knowledge, and your effects have been widely observed in studies about numerous tissues, such as tendons, peripheral nerves, cutaneous tissue, bone, and muscle, in different fields of knowledge. PURPOSE: To analyze the power transmitted by low-level laser therapy (LLLT) to different tissue samples by using distinct wavelengths. METHODS: Skin samples of rat (n = 7, 1.17-1.63 mm) and pig (n = 10; 1.20-2.30 mm); pig fat (n = 10; 2.71-14.01 mm) and pig muscle (n = 10; 1.91-8.91 mm) were analyzed and interposed between the emitter and the power analyzer sensor. All the samples were irradiated sequentially three times, at five equidistant points and average power levels of 35.34(±1.03), 32.40(±0.70), and 42.32(±0.82) mW, for the wavelengths 660, 830, and 904 nm, respectively. Transmitted radiation was measured with a power analyzer connected to a laser emitter. Statistical analysis was performed with a Shapiro-Wilk test followed by ANOVA with Tukey's post hoc test, with a significance level of 5%. RESULTS: The transmitted power of LLLT on skin, fat, and muscle of tissues decreases with the increase of thicknesses, presenting minor attenuation on rat skin, pig fat, and pig muscle for 904 nm. The pig skin has the slight attenuation for 830 nm. CONCLUSION: The LLLT should be applied after considering the transmission loss taking place in different anatomical structures, following the Beer-Lambert law and attenuation coefficient presented for more practical application in many fields.

Quality of life in obese women with symptoms of urinary incontinence / Qualidade de vida em mulheres obesas com sintomas de incontinência urinária / Calidad de vida en mujeres obesas con síntomas de incontinencia urinaria

Abstract Introduction: Obesity is a contributing factor to the development of urinary incontinence (UI). Objective: The objective of this study was to evaluate the prevalence of UI symptoms in women with morbid obesity and their impacts on quality of life (QOL), correlating the influence of age and body mass index (BMI) with the presence of UI. Method: Sixty-five women undergoing preoperative bariatric surgery, aged 35.8 ± 9.97 years, with an average BMI of 45.04 ± 6.79 kg/m2 were asked about the presence of UI symptoms; when they answered positively, the King's Health Questionnaire (validated into Portuguese) was applied. The questionnaire was self-administered and all answers were assigned numerical scores. These scores were distributed according to quartiles and correlated with age and BMI. The level of hypothesis rejection was 5%, and analyses were performed using BioEstat software version 5.3. Results: Among 65 interviewees, 19 (29.23%) had symptoms of UI and went on to answer the questionnaire. The highest-scoring areas were "incontinence impact" (36.8) and "general health perception" (32.9). There was no significant correlation between questionnaire scores and BMI. In the association with age, the "incontinence impact" domain showed a significant, positive and moderate correlation (r = 0.52; p = 0.02). Conclusion: The prevalence of UI symptoms in the sample had a slight negative effect on QOL; however, UI associated with older ages significantly affected the QOL of the studied volunteers.

Resumo Introdução: A obesidade é considerada um fator contribuinte para o desenvolvimento da incontinência urinária (IU). Objetivo: O objetivo deste estudo foi avaliar a prevalência dos sintomas da IU em mulheres obesas mórbidas, seu impacto sobre a qualidade de vida (QV) e correlacionar a influência da idade e do índice de massa corporal (IMC) sobre a presença de IU. Método: Foram avaliadas, 65 mulheres, em pré-operatório de cirurgia bariátrica, com idade de 35,8±9,97 anos e IMC de 45,04±6,79 kg/m 2 sendo questionadas sobre sintomas de IU e, se confirmados, responderam ao King's Health Questionnaire, validado para o português. O questionário foi auto administrado e foram atribuídos valores numéricos às respostas, esses escores foram avaliados em quartis e correlacionados com a idade e o IMC. O nível de rejeição da hipótese foi 5% e as análises foram realizadas com o software BioEstat, versão 5.3. Resultados: Das 65 mulheres que foram entrevistadas, dezenove delas (29,23%) apresentaram os sintomas da IU e responderam ao questionário. Os domínios que apresentaram maior pontuação foram "impacto da IU" (36,8) e "percepção geral da saúde" (32,9). Não foi encontrada correlação significativa entre os escores do questionário e o IMC. Já na associação com a idade, o domínio "impacto da IU" apresentou correlação positiva, significativa e moderada (r = 0,52; p = 0,02). Conclusão: Diante dos achados, com a prevalência de sintomas de IU na amostra estudada, pode-se inferir que a IU compromete pouco a QV, entretanto o aumento da idade quando associada à IU pode afetar significativamente a QV de mulheres obesas classe II e III.

Effect of Breast Cancer Treatment on the Stomatognathic System.

Breast cancer is the most common cancer affecting women in the world and provides functional changes in the human body. Evaluate women submitted to unilateral mastectomy, through electromyographic activity (mandibular rest, right and left laterality, protrusion, maximum voluntary contraction with and without Parafilm, habitual and non-habitual mastication) and thickness (rest and maximum voluntary contraction) of the right temporal muscle (RT), left temporal (LT), right masseter (RM) and left masseter (LM), also the molar bite force (right and left) and compare the data with healthy women. Material and Methods: 32 women were divided into two groups: unilateral mastectomy group (MG), average ± standard deviation 56.50±14.50 years (n=16) and without the disease group (CG), average ± standard deviation 56.56±14.15 years (n=16). The normalized electromyographic data, muscle thickness and maximal molar bite force were tabulated and submitted to statistical analysis (SPSS 21.0; student t test, p≤0.05). Significant statistical differences between MG and CG were found in right laterality, for RM (p=0.02); left laterality, for LT (p=0.01); chewing with peanuts, for RM (p=0.04); chewing with raisins, for LM (p=0.04) and right molar bite force (p=0.03). There was no statistically significant difference between MG and CG for muscle thickness. The results of this study suggest that women undergoing unilateral mastectomy may present functional changes, with emphasis on muscular hyperactivity, lower masticatory efficiency and lower maxillary bite force.

Lower limb auriculotherapy points improves balance in young healthy subjects-assessed by computerized baropodometry.

OBJECTIVE: To analyze the effects of Lower Limb (LL) auricular stimulation points on the static equilibrium of healthy subjects, assessed by computerized baropodometry. METHODS AND MATERIALS: Forty volunteers were assigned to one of two groups: Auriculotherapy (AT) who received unilateral needle stimulation of the coxofemoral, knee, and ankle points. Control (C) who did not receive any stimulation. We analyzed the contact area (CA) and the peak pressure (PP) for both feet at baseline, 20 and 25 min after the baseline was recorded. Three-Way ANOVA (P < 0.05) was used for data analysis. RESULTS: AT showed an increase in CA (F:6.49) and a decrease in PP (F:3.11) at 20 and 25 min, when compared to C. The PP decreased was only for the right LL at 20 and 25 min (F:6.45). CONCLUSION: The auriculotherapy points were able to modify the ipsilateral weight discharge on the same side of the stimulated auricular pavilion.

Ischemic compression and kinesiotherapy on chronic myofascial pain in breast cancer survivors.

OBJECTIVE: assess the effects of ischemic compression and kinesiotherapy on the rehabilitation of breast cancer survivors with chronic myofascial pain. METHODS: A randomized, controlled, blinded clinical trial was performed with 20 breast cancer survivors with myofascial trigger point in the upper trapezius muscle. Patients were randomly allocated to ischemic compression + kinesiotherapy (G1, n = 10) and kinesiotherapy (G2, n = 10). Both groups were submitted to 10 sessions of treatment. The variables evaluated were: Numeric Rating Scale, Pain Related Self-Statement Scale, pressure pain threshold, Functional Assessment of Cancer Therapy-Breast and Infrared thermography. RESULTS: A significant reduction (p < 0.05) was observed in pain intensity after 10 sessions in Groups 1 and 2, a significant increase (p < 0.05) in pressure pain threshold in both the operated and non-operated side after 10 sessions for Group 1. CONCLUSION: Ischemic compression associated with kinesiotherapy increases the pressure pain threshold on the myofascial trigger point in the upper trapezius muscle and reduces the intensity of pain in breast cancer survivors with myofascial pain.

Intra- and Inter-Rater Reliability of Bioimpedance in the Evaluation of Lymphedema Secondary to Treatment of Breast Cancer.

The objective of the study was to evaluate the intra- and inter-rater reliability of bioimpedance in determining upper limb volume in women with lymphedema resulting from breast cancer treatment, as well as its correlation with the upper limb volume calculated by circumferential measurement. A blind cross-sectional study was performed in which 27 women (62.59 ± 10.50 years) were evaluated with upper limb lymphedema secondary to breast cancer treatment. Two examiners performed assessments in the same volunteers independently and twice, with an interval of 1 week between assessments. The collections were performed by the direct tetrapolar multifrequency segmental bioimpedance and by the circumference of the upper limb homolateral to the breast cancer. The results of the circumference showed that the homolateral limb had lymphedema. The intra- and inter-rater analysis showed excellent reliability with intraclass correlation coefficient (ICC) values ranging from 0.954 to 0.999 for the amount of liquid and excellent reliability with ICC values ranging from 0.852 to 0.999 for the electrical impedance of the upper limb with lymphedema. The correlation was strong and negative (p < 0.05) between intracellular, extracellular, and total water when associated with electrical impedance and moderate and positive (p < 0.05) when associated with upper limb volume for all frequencies. The correlations between upper limb volume and water quantities were moderate and positive (p < 0.05). The results indicate that bioimpedance is a reliable method for the evaluation of lymphedema, and the volume of the homolateral upper limb is associated with the amount of water in women with lymphedema secondary to the treatment of breast cancer.

Application of shortwave diathermy to lower limb increases arterial blood flow velocity and skin temperature in women: a randomized controlled trial.

BACKGROUND: Shortwave diathermy (SWD) and microwave diathermy (MWD) are frequently used by physical therapists to treat musculoskeletal conditions. The therapeutic benefits are usually associated with an increase in tissue temperature; however, there is no consensus on the changes in blood flow. OBJECTIVES: 1) To evaluate the behavior of temperature and arterial blood flow after the application of SWD and MWD to the lower limb of healthy women aged 18-30 and 2) to assess whether changes in limb positioning can influence SWD response. METHOD: Among the subjects analyzed, 40 women were eligible to participate in the trial and were randomly allocated to the SWD group or the MWD group. Each group received 20min of diathermy. After receiving the interventions, all patients crossed over to the other group, but the devices were detuned (sham). SWD was applied to the posterior compartment of the thigh and leg, with the knee in 0° and 90° of flexion, and the MWD applied to the posterior thigh. Skin temperature evaluation (digital infrared thermography) and assessment of blood flow velocity (Doppler ultrasound) were performed immediately before and 10 and 20min after the application. RESULTS: Arterial blood flow increased after SWD diathermy (vs. Sham), but not after MWD diathermy. SWD promoted skin heating at the end of therapy in all areas analyzed, remaining above baseline even 20min after the end of the application. MWD diathermy promoted skin heating in the posterior thigh, reflecting a rise in the temperature of the popliteal fossa area that remained for 10min after the end of the application. CONCLUSION: The increase in arterial blood flow velocity depends on the size of the heating area, since it was only observed in the application of the SWD. However, after 20min of application, the position of the lower leg did not affect the heating.
