Respiratory muscles's thermographic analysis in asthmatic youth with and without bronchospasm induced by eucapnic voluntary hyperpnea.

OBJECTIVE: To compare the thermographic pattern of regions of interest (ROI) of respiratory muscles in young asthmatics with and without bronchospasm induced by eucapnic voluntary hyperpnea (EVH). MATERIALS AND METHODS: Cross-sectional study carried out with 55 young (55% male and 45% females) aged 12.5 ± 3.3 years, divided in nine nonasthmatics, 22 asthmatics without exercise-induced bronchospasm compatible response (EIB-cr) and 24 asthmatics with EIB-cr. The diagnosis of EIB was given to subjects with a fall in forced expiratory volume in the first second (FEV1) ≥ 10% compared to baseline. Thermographic recordings of respiratory muscles were delimited in ROI of the sternocleidomastoid (SCM), pectoral, and rectus abdominis intention area. Thermal captures and FEV1 were taken before and 5, 10, 15 and 30 min after EVH. RESULTS: Twenty-four (52.1%) of asthmatics had EIB-cr. There was a decrease in temperature at 10 min after EVH test in the SCM, pectoral and rectus abdominis ROIs in all groups (both with p < 0.05). There was a decrease in temperature (% basal) in asthmatic with EIB-cr compared to nonasthmatics in the rectus abdominis area (p < 0.05). CONCLUSION: There was a decrease in temperature in the ROIs of different muscle groups, especially in asthmatics. The greater drop in FEV1 observed in individuals with EIB-cr was initially associated with a decrease in skin temperature, with a difference between the nonasthmatics in the abdominal muscle area. It is likely that this decrease in temperature occurred due to a temporary displacement of blood flow to the most used muscle groups, with a decrease in the region of the skin evaluated in the thermography.

Analysis of Spin in the Reporting of Studies on Electroanalgesia for Musculoskeletal Pain.

OBJECTIVE: The purpose of this study was to analyze the quality of reporting and presence of spin in abstracts of randomized clinical trials (RCTs) on the use of electroanalgesia for musculoskeletal pain. METHODS: The Physiotherapy Evidence Database (PEDro) was searched from 2010 to June 2021. Inclusion criteria were RCTs using electroanalgesia in individuals with musculoskeletal pain, written in any language, comparing 2 or more groups, and with pain as 1 of the outcomes. Two blinded, independent, and calibrated evaluators (Gwet's AC1 agreement analysis) performed eligibility and data extraction. General characteristics, report of outcomes, quality of reporting (Consolidated Standards of Reporting Trials for Abstracts [CONSORT-A]), and spin analysis (7-item spin checklist and spin analysis per section) were extracted from abstracts. RESULTS: Of 989 studies selected, 173 abstracts were analyzed after screening and eligibility criteria. Mean risk of bias on the PEDro scale was 6.02 ± 1.6 points. Most abstracts did not report significant differences for primary (51.4%) and secondary (63%) outcomes. Mean quality of reporting was 5.10 ± 2.4 points in the CONSORT-A, and spin was 2.97 ± 1.7. Abstracts had at least 1 type of spin (93%), and the conclusion presented the greatest number of spin types. More than 50% of abstracts recommended an intervention without significant differences between groups. CONCLUSION: This study found that the majority of RCT abstracts on electroanalgesia for musculoskeletal conditions in our sample had a moderate to high risk of bias, incomplete or missing information, and some type of spin. We recommend that health care providers who use electroanalgesia and the scientific community be aware of spin in published studies.

Immune Response Related With Skin Thermal Pattern in Judokas: A New Application for Infrared Thermography?

Brito, CJ, Moreira, DG, Ferreira, JJ, Díaz-de-Durana, AL, Miarka, B, Bouzas Marins, JC, and Sillero-Quintana, M. Immune response related with skin thermal pattern in judokas: A new application for infrared thermography? J Strength Cond Res 34(10): 2886-2894, 2020-This study investigated the association between body skin temperature (BST) and immune response after judo training, and compared the immune responses considering 2 post-training skin thermal pattern ("spots"-SPT and "localized"-LOC). For this, we evaluated 32 (25-male) black-belt judokas from the Spanish Junior National Team (18.0 ± 3.5 years, 72.4 ± 18.4 kg, and 17.1 ± 7.5% body fat). White blood cell and BST measurements were performed at pre-training, immediately, 1, and 24-hour post-training. Body skin temperature (° C) was estimated by skin temperature from 4 regions of interest (chest, upper arm, thigh, and calf). The main results indicated that 13 judokas were classified as SPT and 19 as LOC. In comparison with LOC, SPT had a significantly lower BST post-training (SPT = 33.0 ± 0.4 vs. LOC = 33.6 ± 0.8° C; p = 0.016), lower blood concentration of leukocytes (SPT = 7.9 ± 1.9 vs. LOC = 8.9 ± 1.9 cells × 10 per mm; p ≤ 0.001), and neutrophils (SPT = 5.5 ± 1.7 vs. LOC = 6.1 ± 2.2 cells × 10 per mm; p ≤ 0.001). In conclusion, the BST and immune response after judo training seem to be not associated. However, when the skin thermal pattern is considered, the SPT skin thermal pattern presented a lower post-training BST, blood leukocytes, and neutrophils in comparison with the LOC group. These results show a possible relationship between skin thermal pattern and immune responses for the first time; however, further studies are needed to confirm the evidence presented here.

Thermographic imaging in sports and exercise medicine: A Delphi study and consensus statement on the measurement of human skin temperature.

The importance of using infrared thermography (IRT) to assess skin temperature (tsk) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of tsk using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n = 24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%), from 13 different countries completed the Delphi process. An initial list of 16 points was proposed which was rated and commented on by panelists in three rounds of anonymous surveys following a standard Delphi procedure. The panel reached consensus on 15 items which encompassed the participants' demographic information, camera/room or environment setup and recording/analysis of tsk using IRT. The results of the Delphi produced the checklist entitled "Thermographic Imaging in Sports and Exercise Medicine (TISEM)" which is a proposal to standardize the collection and analysis of tsk data using IRT. It is intended that the TISEM can also be applied to evaluate bias in thermographic studies and to guide practitioners in the use of this technique.

Stroke Treatment Associated with Rehabilitation Therapy and Transcranial DC Stimulation (START-tDCS): a study protocol for a randomized controlled trial.

BACKGROUND: Traditional treatment for motor impairment after stroke includes medication and physical rehabilitation. The transcranial direct current stimulation associated with a standard physical therapy program may be an effective therapeutic alternative for these patients. METHODS: This study is a sham-controlled, double-blind, randomized clinical trial aiming to evaluate the efficacy of transcranial direct current stimulation in activities of daily living and motor function post subacute stroke. In total there will be 40 patients enrolled, diagnosed with subacute, ischemic, unilateral, non-recurring stroke. Participants will be randomized to two groups, one with active stimulation and the other with a placebo current. Patients and investigators will be blinded. Everyone will receive systematic physical therapy, based on constraint-induced movement therapy. The intervention will be applied for 10 consecutive days. Patients will undergo three functional assessments: at baseline, week 2, and week 4. Neuropsychological tests will be performed at baseline and week 4. Adverse effects will be computed at each session. On completion of the baseline measures, randomization will be conducted using random permuted blocks. The randomization will be concealed until group allocation. DISCUSSION: This study will investigate the combined effects of transcranial direct current stimulation and physical therapy on functional improvement after stroke. We tested whether the combination of these treatments is more effective than physical therapy alone when administered in the early stages after stroke. TRIAL REGISTRATION: NCT02156635---May 30, 2014. Randomization is ongoing (40 participants randomized as of the end of December 2015).

Mandible reconstruction: History, state of the art and persistent problems.

BACKGROUND: Mandibular reconstruction has been experiencing an amazing evolution. Several different approaches are used to reconstruct this bone and therefore have a fundamental role in the recovery of oral functions. OBJECTIVES: This review aims to highlight the persistent problems associated with the approaches identified, whether bone grafts or prosthetic devices are used. A brief summary of the historical evolution of the surgical procedures is presented, as well as an insight into possible future pathways. STUDY DESIGN: A literature review was conducted from September to December 2012 using the PubMed database. The keyword used was "mandible reconstruction." Articles published in the last three years were included as well as the relevant references from those articles and the "historical articles" were referred. This research resulted in a monograph that this article aims to summarize. RESULTS: Titanium plates, bone grafts, pediculate flaps, free osteomyocutaneous flaps, rapid prototyping, and tissue engineering strategies are some of the identified possibilities. The classical approaches present considerable associated morbidity donor-site-related problems. CONCLUSION: Research that results in the development of new prosthetics devices is needed. A new prosthetic approach could minimize the identified problems and offer the patients more predictable, affordable, and comfortable solutions. CLINICAL RELEVANCE: This review, while affirming the evolution and the good results found with the actual approaches, emphasizes the negative aspects that still subsist. Thus, it shows that mandible reconstruction is not a closed issue. On the contrary, it remains as a research field where new findings could have a direct positive impact on patients' life quality. The identification of the persistent problems reveals the characteristics to be considered in a new prosthetic device. This could overcome the current difficulties and result in more comfortable solutions. Medical teams have the responsibility to keep patients informed about the predictable problems related with each elected approach, even understanding that a perfect reconstruction is a secondary goal when compared with maintenance of life.

Exercise-associated thermographic changes in young and elderly subjects.

This study aimed at evaluating the thermographic changes associated with localized exercise in young and elderly subjects. An exercise protocol using 1 kg load was applied during 3 min to the knee flexors of 14 elderly (67 +/- 5 years) and 15 young (23 +/- 2 years) healthy subjects. The posterior thigh's skin temperature of the exercised limb and contralateral limb were measured by infrared thermography on pre-exercise, immediately post-exercise, and during the 10-min period post-exercise. Difference (p < 0.01) between elderly and young subjects was observed on pre-exercise temperature. Although differences were not observed between pre-exercise and immediately post-exercise temperature in the exercised limb, thermographic profile displayed heat concentration in exercised areas for both groups. Temperature reduction was only observed for the young group on the 10-min post-exercise (p < 0.05) in the exercised limb (30.7 +/- 1.7 to 30.3 +/- 1.5 degrees C). In contrast, there was a temperature reduction post-exercise (p < 0.01) in the contralateral limb for both groups. These results present new evidences that elderly and young subjects display similar capacity of heat production; however, the elderly subjects presented a lower resting temperature and slower heat dissipation. This work contributes to improve the understanding about temperature changes in elderly subjects and may present implications to the sports and rehabilitation programs.
