Abstract
OBJECTIVE To identify the effect of exercise interventions on physical frailty in community-dwelling older adults. METHODS Relevant articles were searched in MEDLINE, LILACS, Scielo, Embase, and PEDro in November 2022, based on a protocol registered in PROSPERO and according to items prescribed in Report for Systematic Reviews and Meta-Analyses, using Health Sciences Descriptors (DeCS) and free terms for search strategy, with no language restrictions. The studies were considered if they had been published between January 2010 and November 2022, and were randomized clinical trials in which pre-frail and frail older community-dwelling adults had undergone exercise-based physical therapy. RESULTS The systematic review found 5360 citations; after screening, abstract, and full-text screening for eligibility, seven studies were included, involving 1304 participants overall. The exercise modalities differed substantially between studies. The meta-analysis identified a statistically significant difference in frailty between older adults who exercised compared with those who exercised with no or minimal intervention. No heterogeneity between articles was observed, and the risk of bias was considered low according to funnel plot visual inspection. CONCLUSIONS The results of this review suggest that physical therapy programs are effective in decreasing levels of physical frailty in community-dwelling older adults.

Abstract
OBJECTIVE Accurate assessment of burn depth and burn wound healing potential is essential to determine early treatments. Infrared thermography (IRT) is a non-invasive and objective tool to do this. This systematic review evaluated the accuracy of IRT to determine burn wound healing potential. METHOD This systematic review and meta-analysis used MEDLINE, EMBASE, CINAHL, PEDro, DiTA and CENTRAL databases. IRT data were extracted from primary studies and categorised into four cells (i.e., true positives, false positives, true negatives and false negatives). Subgroup analysis was performed according to methods used to capture thermal images. RESULTS The search strategy identified 2727 publications; however, 15 articles were selected for review and 11 for meta-analysis. In our meta-analysis, the accuracy of IRT was 84.8% (63% sensitivity and 81.9% specificity). CONCLUSION IRT is a moderately accurate tool to identify burn depth and healing potential. Thus, IRT should be used carefully for evaluating burn wounds.

Abstract
The aim of this study is to assess the effect of photobiomodulation therapy (PBMT) on functional performance concerning strength, fatigue, and functional capacity in healthy individuals. This systematic review with meta-analysis involved searches on data platforms and active searches of randomized clinical trials, focusing on PBMT as the sole intervention. Primary outcomes assessed included strength, fatigue, and functional capacity. Three reviewers screened studies by title and abstract using Rayyan, and data were extracted using a specific form. Bias risk was assessed using RoB2, and confidence in the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The RevMan was used for meta-analysis. Sixteen studies were included, totaling 340 individuals (183 males and 157 women). Most articles presented a low risk of bias. Variability was observed in device types and application domains, including wavelengths (655-905 nm), power (10-200 nW), energy (0.6-30 J per point), and time (30-100 s per point). PBMT improved fatigue recovery (mean difference: 5.87; 95% CI 3.83, 7.91). There was no enhancement in strength (peak torque: mean difference 12.40; 95% CI -5.55, 30.55; one-repetition maximum test: mean difference 39.97, 95% CI -2.44, 82.38; isometric and isokinetic strength: mean difference 2.77, 95% CI -14.90, 20.44) nor improvement in short-term (mean difference 0.67, 95% CI -0.58, 1.91) and long-term (mean difference 18.44, 95% CI -55.65, 92.54) functional capacity. PBMT may aid in favoring fatigue recovery in healthy individuals; however, there's no evidence to support PBMT enhancing strength or improving functional capacity.

Abstract
INTRODUCTION The different phases of a woman's life, such as the reproductive phase and menopause, are points of great hormonal oscillation, especially estrogen and progesterone, which can interfere with skin temperature. OBJECTIVE To describe and compare skin temperatures of women during their physiological menstrual cycle, the use of exogenous hormones and menopause over a period of 28 days. METHOD This is a prospective observational study using a quantitative approach. A total of 45 volunteers participated and were equally allocated into three groups: Exogenous Hormone Group (EHG), Physiological Menstrual Cycle Group (PMCG) and Menopause Group (MG). All were submitted once a week to body composition measurements over a period of 28 days using an InBody 120 bioimpedance scale, and skin temperature using a FLIR model T-360 thermographic camera. RESULTS No significant differences were found between the mean skin temperature of women with a physiological cycle using exogenous hormones and menopause in relation to the evaluation time or between groups. However, younger women had higher temperatures in specific skin regions, such as in the breast, lower abdomen and thigh (P < 0.05) compared to menopausal women. In addition, negative correlations were observed between body fat and skin temperature of the breasts, trunk, abdomen, upper limbs and right lower limb (P < 0.05). CONCLUSION It was observed that the general skin temperature of women is not altered due to exogenous hormones, menstrual cycle phase or menopause, and that skin temperature tends to be lower in regions with an accumulation of adipose tissue.

Abstract
Introduction: Breast engorgement (BE) is a problem that affects many women, especially in the first days of breastfeeding, producing inflammatory symptoms. Nonpharmacological therapies are inexpensive, safe, and can produce symptom relief. Objective: This study aims to analyze the safety of therapeutic ultrasound regarding possible risks of overheating and the effects of its use alone and associated with lymphatic drainage (LD) in women. Material and Methods: Effectiveness is measured through thermography, visual analog scale, and six-point scale of BE. This is a nonrandomized clinical trial with a sample of 34 in the ultrasound group (G1), 28 in the ultrasound and LD group (G2), and 37 in the control group (G3). Results: The mean reduction for engorgement was 1.3 ± 0.8 to G1, 1.4 ± 1.0 to G2, and 1.2 ± 0.9 to G3 according to the six-point scale. The mean reduction for pain level was 3.6 ± 2.1 to G1, 4.0 ± 3.1 to G2, and 4.0 ± 2.2 to G3 according to the visual analogue scale. Conclusion: It was observed that all therapies were effective in reducing the level of engorgement, according to the six-point scale. However, combined ultrasound and LD therapy has been shown to be more effective in reducing the level of pain. Brazilian Registry of Clinical Trials (RBR-6btb6zz).

Abstract
Background Burns are a global public health problem and cause approximately 180,000 deaths annually, mainly in low- and middle-income countries. Topical antibiotics and occlusive dressing are standard treatments for burns not requiring a skin graft. However, physiotherapy has low-cost phototherapeutic and electrophysical resources (e.g., light-emitting diode [LED]) that may accelerate burn healing. This study aims to compare the re-epithelialization rate of second-degree burns, pain, pruritus, skin temperature, quality of wound healing, and scar quality and mobility among individuals undergoing treatment with red LED, infrared LED, and simulated photobiomodulation. Methods This is a double-blinded, three-arm parallel-group, randomized controlled superiority trial. Individuals of both sexes, aged over 18 years, and with second-degree burns will be included. The sample will be divided into three groups of 13 individuals: two will receive LED therapy (red or infrared) and one placebo. Pain, pruritus, skin temperature, and wound size will be assessed daily. Interventions will take place until complete healing, when scar mobility and quality will be evaluated. Data will be presented as mean and 95% confidence interval and analyzed using mixed linear models. Discussion This randomized controlled trial has minimal risk of bias and intends to identify the ideal type, procedures, and doses of photobiomodulation to heal burns, which are not standardized in clinical practice. Positive results will allow the implementation of the technique in burn and wound guidelines. Trial registration Brazilian Clinical Trials Registry (ReBEC) RBR-8bfznx6. Registered on October 13, 2021

Abstract
BACKGROUND: Parkinson’s disease (PD) is a progressive neurodegenerative disorder, characterized by cardinal motor symptoms in addition to cognitive impairment. New insights concerning multisite non-invasive brain stimulation effects have been gained, which can now be used to develop innovative treatment approaches. OBJECTIVE: Map the researchs involving multisite non-invasive brain stimulation in PD, synthesize the available evidence and discuss future directions. METHODS: The databases PubMed, PsycINFO, CINAHL, LILACS and The Cochrane Library were searched from inception until April 2020, without restrictions on the date of publication or the language in which it was published. The reviewers worked in pairs and sequentially evaluated the titles, abstracts and then the full text of all publications identified as potentially relevant. RESULTS: Twelve articles met the inclusion criteria. The target brain regions included mainly the combination of a motor and a frontal area, such as stimulation of the primary motor córtex associated with the dorsolateral prefrontal cortex. Most of the trials showed that this modality was only more effective for the motor component, or for the cognitive and/or non-motor, separately. CONCLUSIONS: Despite the results being encouraging for the use of the multisite aproach, the indication for PD management should be carried out with caution and deserves scientific deepening.

Abstract
OBJECTIVES To compare acute effects of isometric abdominal exercises performed with or without vibration on the electromyographic activity and cutaneous temperature in the abdominal region of physically active individuals. METHODS A randomized controlled crossover clinical trial was undertaken in thirty volunteers who completed one unique session of two different protocols of interventions apart from a week from each other, in a two-week study protocol. The subjects were randomly divided in to two groups of 15 volunteers; both were assigned to perform board exercise (30 s on the front, right and left lateral boards, with a rest interval of 2 min). The first group performed it on a vibrating platform at a frequency of 30 Hz for the first week, while the remaining participants executed the same exercise without stimulates vibration. In the second week the protocol was inverted. The outcome were surface electromyography (EMG) data for the rectus abdominis muscle (RAM) and cutaneous temperature (CT) of the abdominal region. Normality was accepted, and Student's t-tests were used to compare the measurements for dependents variables (P < 0.05). RESULTS There were no differences in RAM activation and CT between protocols with or without vibration (P > 0.05). CT increased (P = 0.001) after both the exercises with and without vibration. CONCLUSION The results suggest that there were no effects in cutaneous temperature or muscle activation through the use of vibration associated with isometric abdominal exercises.

Abstract
The purpose of this study was to analyze skin temperature (Tsk) responses after a short-term maximum effort test in middle-distance runners. A quasi-experimental study was conducted with ten men (age 23.5±5.10 years) who trained 5 days per week, 2 to 3 hours per day, and were submitted to thermographic evaluation before and after Cooper's 12-minute run test (CRT). The mean temperature of the anterior-superior, posterior-superior, anterior-inferior, and posterior-inferior regions was compared between the sides (i.e., left and right) before and after CRT. The paired t-test showed a significant decrease in Tsk after CRT in the following regions: right pectoralis major (-3.4%), left pectoralis major (-3.4%), and abdomen (-5%) in the anterior-superior view (p<0.01); and in the upper right trunk (-1.9%), upper left trunk (-1.9%) and lower back (-2.9%) in the posterior-superior view (p<0.05). In the lower limbs, a significant increase in temperature of the left knee (1.6%), and right (3.6%) and left ankles (2.9%) in the anterior view (p<0.05), as well as in the right (4.3%) and left ankles (3.7%) in the posterior view (p<0.05) were observed. There was no difference in temperature between the right and left sides. In conclusion, the Tsk change of middle-distance runners was symmetrical between sides, decreasing in upper limbs and trunk and increasing in lower limbs after a short-term maximum effort test.

Abstract
This study aimed to investigate the acute effects of stretching exercise on skin temperature, flexibility, passive muscle stiffness, and pain during hamstring stretching in healthy young subjects. Thirty-one participants (n=31) were randomly divided into 2 groups: an experimental group (EG, n=15), which was submitted to hamstring stretching exercise for 180 sec, and the control group (n=16), which was not exercised. Skin temperature (TsK) was collected in subjects' posterior thigh using a thermographic camera at 7 time points with intervals of 30 sec each: T0 (rest), T30, T60, T90, T120, T150, and T180. In addition, the knee range of motion, passive stiffness and muscle soreness (visual analogue scale) were recorded during the stretching procedure at the same times. The EG presented a small but progressive increase in TsK (30.8°C±0.6°C to 31.1°C±0.6°C, P<0.01), with an increased range of motion (P<0.01) and muscle soreness levels (P<0.01) during the gradual hamstring stretching protocol. Additionally, there was an increment of passive stiffness (P<0.01) that was partially reversed toward the end of the stretching period. This research presents evidence that constant, passive and progressive stretching of the hamstrings progressively increased the local TsK by about 0.3°C after 180 sec of stretching. These findings may help to understand the effects of repeated stress on the muscle-tendon unit and the role of muscle stretching in warm-up protocols and rehabilitation.

Abstract
AbstractThe purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players. Seventeen female volleyball players (18.94±2.49 years; 65.45±9.49 kg; 1.71±0.05 m; BMI=22.0±2.67 kg/m²) took part in this study. The dynamic balance was assessed through the Star Excursion Balance Test (SEBT). Comparisons between stabilization (no stabilizer/NS, orthosis/ORT and functional bandaging/FB) modes and the SEBT grid lines and inter-limb were carried out. The SEBT assessment showed a significant difference between the groups NS x ORT and NS x FB (p < .01), and between the lines (p< .01). Significant line/limb interaction in DL and NDL (p< .01) was detected. The external supports tested herein showed similar effects on balance, restricting lower limb's reach in the SEBT execution in some of tested directions.

Abstract
The aim of the study was to compare static postural balance of healthy individuals of three age groups in different conditions of support and vision. Seventy one individuals, divided into 3 groups, were analyzed: young group (YG: 22.2 ± 2.1 years), middle aged group (MAG: 50.7 ± 5.7 years) and older individuals group (EG: 66.8 ± 5.4 years). Their balance was tested on a force platform, under 3 support and 3 visual conditions. Measures included: total (TD), anterior-posterior (APD) and mediolateral displacement (MLD) of the center of pressure (CoP). ANOVA revealed significant differences for interactions between group X support conditions and group X visual conditions for the 3 variables (p<0.01), with greater displacements for the MAG and EG groups during single-leg stance with partial and occluded vision (p<0.05). Static postural balance decreased over time in healthy individuals, and conditions of support and visual negatively affected balance with the increment of age.
