Title: Transmissão de força miofascial entre grande dorsal e glúteo máximo contralateral entre indivíduos com e sem lombalgia crônica
Abstract: The thoracolumbar fascia (TLF) plays an important role in lumbar stabilization and is considered a path of transmitting myofascial force. The superficial layer of this fascia connects to the latissimus dorsi (LD) and gluteus maximus (GM) muscles, enabling the transmission of oblique force between the trunk and lower limbs. Chronic low back pain can modify the mechanical properties of the TLF, which can reduce the efficiency of the myofascial force transmission. The objective of this study was to investigate whether there is a difference in the myofascial force transmission between LD and contralateral GM between individuals with and without chronic low back pain. Forty-eight individuals divided into a low back pain group and a control group participated in the study. Lumbar stiffness variables were evaluated, using a non-invasive digital myotonometer, and passive hip properties (resting position, torque and hip stiffness) were evaluated using an isokinetic dynamometer in two test conditions: relaxed LD and contracted LD. Mixed analysis of variance was used to evaluate the main and interaction effects for the variables of interest. In the presence of an interaction effect, pre-planned contrasts were used to investigate the direction of the interactions. LD contraction increased lumbar stiffness in both groups (p < 0.001), but there was a change in the resting position towards a more lateral rotation of the hip and an increase in passive torque only in the control group (p < 0.001). Furthermore, LD contraction increased passive hip stiffness in both groups, with the hip in the chronic low back pain group already showing greater stiffness than the control group, even in the relaxed LD condition. The present study identified that the myofascial force transmission between LD and contralateral GM via FTL is reduced in individuals with chronic low back pain.

Title: Queixas de sono de indivíduos com distúrbios musculoesqueléticos em tratamento fisioterapêutico: um estudo observacional transversal
Abstract: OBJECTIVE: The objectives of this study were to 1) identify the frequency of occurrence of sleep complaints in individuals undergoing physiotherapeutic care due to musculoskeletal disorders; and 2) investigate which complaints are most prevalent in this population. METHODS: This was a cross-sectional observational study that included individuals aged 18 years or older, with musculoskeletal disorders, undergoing physiotherapeutic treatment, who were recruited from physiotherapy clinics in the city of Belo Horizonte that were invited and agreed to participate in this study. Sociodemographic variables were collected using a pre-structured form and sleep complaints were collected using the Sleep Complaints Questionnaire. The data collection was carried out online using the Google Forms platform. For data analysis, a descriptive analysis was carried out in which measures of central tendency and variability of the variables were presented to characterize the sample. RESULTS: A total of 85 individuals, with a mean age of 51.4 years (± 16.9 years), and majority of females (56.5%) participated in the study. We found that 92.9% of the sample had at least one sleep complaint. The predominant sleep complaints were waking up during the night (70.6%), feeling of insufficient sleep or waking up tired (49.4%) and nighttime awakenings (45.3%). CONCLUSION: Our findings showed a high prevalence of sleep complaints in individuals with musculoskeletal disorders who are undergoing physiotherapeutic treatment and that the most prevalent sleep complaints reported were: waking up during the night, feeling of insufficient sleep or waking up tired and nighttime awakenings.

Title: Tradução e avaliação das propriedades de medida da versão brasileira do Quality FM para crianças e adolescentes com paralisia cerebral
Abstract: Improvement in the quality of movement in children and adolescents with cerebral palsy (CP) can be an important basis for the acquisition of new gross motor skills and needs to be investigated and measured in a quantitative and standardized way. The objective of this dissertation study was to translate into Brazilian Portuguese and to assess the properties of measurement of face validity, reliability and discriminant validity of the Quality FM (QFM) for children and adolescents with cerebral palsy (CP) at the Gross Motor Function Classification System levels. (GMFCS) I, II and III. The translation of the QFM was conducted in four stages: translation, synthesis of translation, back-translation and review of the translation by a committee of experts. Face validity was assessed with 19 physiotherapists who judged the relevance and comprehensiveness of the test items. Test-retest reliability was tested with 30 children and adolescents with CP over an interval of 7 to 30 days. Inter-rater reliability was tested with 50 children and adolescents with CP, by two examiners. Discriminant validity was tested with 86 children and adolescents with CP. Test-retest reliability showed good to excellent rates (0.86 to 0.98). Inter-rater reliability presented excellent rates (0.96 to 0.99). All QFM attributes were able to discriminate participants by GMFCS level (p<0.0001). The results of this study indicate that the translated version of the QFM has acceptable measurement properties and is a tool for Brazilian professionals to assess the quality of movement in children and adolescents with CP.

Title: Comparação da transmissão de força miofascial entre os músculos grande dorsal e glúteo máximo em corredores e sedentários: um estudo transversal
Abstract: Myofascial force transmission (MFT) has already been demonstrated in cadavers and in vivo in different regions of the musculoskeletal system, such as between the latissimus dorsi (LD) and gluteus maximus (GM) muscles. The efficiency of MFT appears to be influenced by tissue passive characteristics. It is known that the mechanical stimulus induced by regular physical activity can induce changes in the stiffness of biological tissues and it is possible that specific physical and sporting activities, such as running, may require greater use of the force transmission pathway between LD and GM. The sports gesture of running involves a coupled movement of shoulder extension on one side and contralateral hip extension, a moment in which the action of the LD and GM muscles can generate an increase in tension in the thoracolumbar fascia, stimulating MFT between the muscles. Considering this movement pattern and the fact that runners have greater tissue stiffness, it is possible that runners have greater MFT between LD and GM when compared to sedentary people. The objectives of the present study were to investigate whether (1) the contraction of the LD during shoulder extension modifies the stiffness of the lumbar region, and the passive properties of the contralateral hip in runners and sedentary people, which would indicate the occurrence of MFT and (2) to verify whether this MFT is higher in runners than in sedentary people. 54 individuals participated in this study, 27 in each group. Assessments of lumbar stiffness were carried out with a myothonometer and of the passive properties of the hip (hip resting position, passive hip torque, and passive hip stiffness) with the isokinetic dynamometer in two test conditions: LD relaxed and LD contracted. Mixed analysis of variance was used to evaluate the main and interaction effects for the variables lumbar stiffness, hip resting position, passive hip torque, and stiffness. In the presence of an interaction effect, pre-planned contrasts were used to investigate the direction of the interactions. Runners had a more pronounced increase in lumbar stiffness during LD contraction (p = 0.017). Furthermore, LD contraction led to a change in the resting position of the hip towards external rotation and an increase in torque and passive hip stiffness in both groups. Thus, the results of the study demonstrated that MFT occurred in both groups. The analyzes also demonstrated that, although the magnitude of the change in lumbar stiffness was greater in runners, the MFT was not greater in this group when compared to the sedentary group. As far as we know, this was the first study to carry out this analysis, therefore, it is necessary to develop research that carries out this investigation through, for example, elastography, and that analyzes other factors, such as the effect of GM tension in lumbar stiffness and MFT in the direction of GM contraction for the contralateral LD in runners and sedentary people.
