Efficacy and safety of hemodialysis strategies for pregnant women with chronic kidney disease: Systematic review.

Pregnancy in chronic kidney disease (CKD) women is relatively rare, and the less risky choice of hemodialysis is unknown. The objective of this systematic review was to identify, systematically evaluate and summarize the available evidence on the efficacy and safety of hemodialysis strategies for pregnant CKD women. Sensitive search strategies were applied to six databases without data or language restrictions. Comparative (randomized and non-randomized) studies were prioritized. Two reviewers independently selected, extracted, and critically evaluated data from studies. The risk of bias assessment was performed using the ROBINS-I tool, considering the study design (non-randomized comparative observational studies). The certainty of the evidence was assessed using the GRADE approach. From 7210 references identified, six retrospective cohort studies were included (576 women). The effects of intensive hemodialysis (over 20 h/week) are uncertain for maternal and neonatal mortality (Peto odds ratio [OR] 0.85; 95% confidence interval [95% CI] 0.26-2.80), miscarriage (Peto OR 0, 38; 95% CI 0.12-1.23), stillbirths (Peto OR 0, 56; 95% CI 0.13-2.31), preterm birth (Peto OR 0.87; 95% CI 0.33-2.28), low birth weight (Peto OR 0.71; 95% CI 0.20-2.50) and congenital anomalies rates. The certainty of the evidence was very low due to studies methodological limitations and effect estimates imprecision. The uncertainty about intensive versus conventional hemodialysis effects for pregnant women with CKD and the imprecision in the estimated effects precludes any recommendation. The strategy choice must consider treatment availability, costs, and maternal social aspects until future studies provide more reliable evidence. PROSPERO CRD42021259237.

Sticky Mittens Training to Improve Reaching Skills and Manual Exploration of Full-Term and At-Risk Infants: A Systematic Review.

AIM: To systematically review evidence of the effectiveness of sticky mittens training to improve reaching skills and manual exploration of full-term and at-risk infants and optimal training dosage. METHODS: The Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided this systematic review. The electronic search was performed from September 2017 to August 2021 on PubMed, Scopus, Science Direct, and Cochrane databases. Eligibility criteria followed PICO terms: clinical trials investigating the effects of sticky mittens training on reaching skills and manual exploration of full-term and at-risk infants. PEDro scale and GRADE assessed methodological quality and quality of evidence, respectively. RESULTS: Eight studies (313 children) were included. Five studies found statistically significant differences between experimental and control groups (62.6%). One study presented high methodological quality. Evidence synthesis showed very low and low evidence of the beneficial effects of sticky mittens training in full-term and at-risk infants, respectively. CONCLUSIONS: Findings suggest that sticky mittens training facilitates reaching skills and manual exploration. However, results should interpretation with caution because studies targeted full-term infants. Future research should focus on infants at risk or with motor impairments since sticky mittens training seems to show positive effects and is easy to apply.

Instruments to assess upper-limb function in children and adolescents with neuromuscular diseases: a systematic review.

AIM: To synthesize clinical and scientific evidence regarding the instruments available to assess upper-limb function in paediatric patients with neuromuscular disease (NMD). METHOD: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines (Prospective Registry of Systematic Reviews no. CRD42020140343). Two independent reviewers searched the PubMed/MEDLINE, LILACS, Embase, and Scopus databases. Inclusion criteria were cross-sectional or longitudinal studies or randomized controlled trials that used scales or questionnaires to assess upper-limb function in paediatric patients with NMDs. The COSMIN Risk of Bias checklist and criteria for good measurement properties were applied to assess the methodological quality of the instruments. RESULTS: In total, 34 articles and 12 instruments were included. The Brooke Upper Extremity (n=16) and Performance of Upper Limb (PUL) (n=12) instruments were the most used tools. The PUL and Duchenne muscular dystrophy (DMD) Upper Limb patient-reported outcome measures (PROMs) tested more measurement properties and provided higher methodological quality scores for patients with DMD. Likewise, the Revised Upper Limb Module (RULM) was the most suitable instrument for patients with spinal muscular atrophy. No instrument has been devised to assess upper-limb function in patients with Charcot-Marie-Tooth disease and no other disease-specific instruments were found. INTERPRETATION: The PUL, DMD Upper Limb PROM, and RULM are the most suitable instruments to assess upper-limb function in the two most prevalent paediatric NMDs. The identified gaps and methodological flaws of the available instruments indicate a need to develop high-quality instruments to assess other types of paediatric NMDs. What this paper adds The most suitable observer-rater instrument to assess upper-limb function in Duchenne muscular dystrophy (DMD) is the Performance of Upper Limb. The most suitable observer-rater instrument to assess upper-limb function in spinal muscular atrophy is the Revised Upper Limb Module. The DMD Upper Limb patient-reported outcome measure is recommended to assess the upper-limb performance of patients with DMD. Literature gaps and methodological flaws indicate the need to develop high-quality instruments to assess other types of paediatric neuromuscular disease.

Is physical capacity associated with the occurrence of musculoskeletal symptoms among office workers? A cross-sectional study.

PURPOSE: Low physical capacity is hypothesized to be associated with the presence of musculoskeletal symptoms. Therefore, our aim was to investigate whether physical capacity is associated with the presence of musculoskeletal symptoms in the neck, shoulders, and thoracic and lumbar spine among office workers. METHODS: Sixty-seven office workers, recruited at the university, were evaluated regarding the presence of musculoskeletal symptoms through the Nordic Musculoskeletal Questionnaire (NMQ). Measurements of muscle strength and endurance of shoulder abduction, endurance of trunk flexion and extension, and back and leg flexibility were obtained. Data were analysed through a binomial logistic regression model, considering physical capacity as the independent variable and symptoms as the dependent variable. An adjusted model was also applied that controlled for individual and occupational covariates. RESULTS: The basic model showed a significant association between reduced shoulder abduction strength and neck (OR: 0.87; 95% CI 0.78-0.98) and shoulder symptoms (OR: 0.88; 95% CI 0.78-0.99), and between reduced back and leg flexibility and thoracic spine symptoms (OR: 0.92; 95% CI 0.85-0.99). The adjusted model, after controlling for the covariates, demonstrated that reduced shoulder abduction strength (OR: 0.70; 95% CI 0.52-0.94) and reduced back and leg flexibility (OR: 0.81; 95% CI 0.66-0.99) were associated, instead, with the occurrence of neck and low back symptoms, respectively, in the last 12 months. CONCLUSIONS: Physical capacity is associated with the presence of neck and low back symptoms in office workers. Furthermore, individual and occupational characteristics affect the relationship between physical capacity and musculoskeletal symptoms and should be considered for understanding and managing musculoskeletal symptoms among office workers.

The effects of cryotherapy on pain and function in individuals with knee osteoarthritis: a systematic review of randomized controlled trials.

OBJECTIVE: To investigate the effectiveness of cryotherapy on pain and physical function in knee osteoarthritis. DATA SOURCES: An electronic search was performed up to February 2019 on PubMed/MEDLINE, EMBASE, CINAHL, Lilacs, Cochrane, Web of Science, Ibecs, and Scielo databases with keywords knee osteoarthritis and cryotherapy. METHODS: Two authors independently performed the study selection. All languages and publication dates were considered. The PEDro scale was used to assess the methodological quality of the studies, and the body of evidence was analyzed and synthesized using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The clinical relevance of the included studies was evaluated using the criteria proposed in the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Of the five studies, 202 subjects were included. All studies included participants with established knee osteoarthritis. The mean PEDro score was 4.20/10, and meta-analysis was not possible due to heterogeneity among the studies. The mean clinical relevance was 3/5. Only two studies were considered for analysis based on the GRADE approach, and low level of evidence was synthesized regarding the effectiveness of cryotherapy for pain management, knee stiffness, knee range of motion, and physical function. Application techniques, frequency, and duration did not affect outcomes. CONCLUSIONS: There were insufficient primary studies to draw any conclusions about the effectiveness of cryotherapy on pain and physical function on individuals with knee osteoarthritis.

Effect of physical therapy interventions in individuals with primary thumb carpometacarpal osteoarthritis: a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis aimed to investigate the effect of physiotherapeutic interventions in individuals with thumb primary CMC OA on the outcomes of pain, hand function, grip or pinch strength. METHODS: RCTs that used some type of physiotherapeutic intervention compared to a passive or active control group were included. The quality of the evidence was assessed using the GRADE approach and, for the calculation of the meta-analysis, the standardized difference of means (SMD) was used. RESULTS: Nineteen studies (n = 1477) were included and eight studies (n = 568) underwent meta-analysis. Orthosis intervention was superior to passive control group for pain improvement (SMD = -1.02, p = 0.03, very low evidence), grip strength (SMD = 0.45, p = 0.02, very low evidence) and pinch strength (SMD = 1.78, p = 0.01, very low evidence), but there was no improvement in hand function (p = 0.54). The use of a neoprene orthosis was similar to the use of a thermoplastic orthosis in improving pain (p = 0.38), hand function (p = 0.50), grip strength (p = 0.42) and pinch strength (p = 0.14). The use of short thermoplastic orthosis was also similar to long thermoplastic orthosis in improving pain (p = 0.88) and hand function (p = 0.58). CONCLUSION: The use of orthoses is superior to no intervention in all outcomes, exception hand function.IMPLICATIONS FOR REHABILITATIONThe use of orthosis is recommended for the treatment of patients with rhizoarthrosisUse of orthosis is better than no intervention in improving pain, grip and pinch strength.The type of orthosis (neoprene or thermoplastic, short or long thermoplastic) does not affect the clinical improvement of the individual to the outcomes of pain, hand physical function, grip and pinch strength.

Efficacy and safety of home-based intravenous antibiotic therapy among adults: a systematic review.

The aim of this study was to identify, systematically assess and summarise the available evidence about the efficacy and safety of intravenous home antibiotic therapy. In this systematic review, we considered studies of adults with any kind of infection and recommended intravenous antibiotic therapy. We included studies comparing therapy given at the patient's home versus any other setting (other levels of healthcare services or sites). We performed wide and sensitive literature searches with strategies adjusted for each of the electronic databases, including CINAHL, ClinicalTrials.gov, Cochrane Library, Embase, Epistemonikos, Health System Evidence, LILACS, MEDLINE and grey literature (OpenGrey). We used the Cochrane risk-of-bias and GRADE tools to evaluate the risk of bias and the certainty of evidence. At least two reviewers, working independently, selected the studies, extracted data and critically evaluated the evidence. We performed random-effects meta-analyses where possible. From 20 099 references initially identified, we included 6 randomised controlled trials (RCTs) with 616 participants. We considered the certainty of the body of evidence as low to very low regarding infection resolution after 6 weeks, risk of adverse events, mortality and clinical status. Based on six RCTs with considerable risk of bias, this systematic review found low or very low evidence about the advantages of intravenous antibiotic therapy at home. The imprecision of the results does not allow us to recommend or contraindicate the use of this strategy in clinical practice. [PROSPERO register: this review protocol was prospectively submitted at the PROSPERO register base at 31 January 2021 (submission no. 42021234454)].

Respiratory Disorders in Parkinson's Disease.

BACKGROUND: Parkinson's disease (PD) non motor symptoms may present early in the disease course and worsen with advancing disease. Respiratory changes can affect individuals to remain physically active, contributing to a reduction of functionality and quality of life. OBJECTIVE: The aim of this systematic review is to synthesize evidence of respiratory disorders in patients with PD. METHODS: An electronic search was performed up to November 2020 on PubMed-MEDLINE, Embase, Web of Science, Lilacs, Cinahl, and Cochrane using the following keyword combination: [("Parkinson disease") AND ("respiratory function tests" OR "evaluation") AND ("respiratory system" OR "respiration disorders" OR "respiratory muscles")]. RESULTS: The electronic search resulted in 601 references in English or Portuguese. The selection process and data extraction were made by two independent reviewers. We selected 19 studies including cross-sectional studies that investigated the respiratory disorders in patients with PD through pulmonary function, respiratory muscle strength, or physical capacity evaluation. We excluded studies that considered patients with other diseases. Eighteen studies evaluated the pulmonary function in patients with PD, eleven studies verified the influence of PD on respiratory muscle strength, and three studies assessed the physical capacity through functional tests. CONCLUSION: The evidence showed that PD patients have higher chances to present a pulmonary dysfunction, either obstructive or restrictive, when compared to healthy subjects. In addition, these patients present lower respiratory muscle strength and a consequent decrease in physical capacity in endurance exercises. The respiratory impairment in PD seems to be directly related to the progression of the disease.

Does sEMG normalization change results on sex differences in the activation of the shoulder girdle muscles during a simulated work task?

The aim was to investigate if the method of normalizing surface electromyography (sEMG) can change results on sex differences in the muscular activation of the shoulder girdle muscles during a simulated work task. sEMG was recorded in 36 asymptomatic participants (17 females, 19 males) from four parts of trapezius and from serratus anterior muscles during a simulated work task. Four normalization methods, one involving maximal voluntary contractions (MVCs) and three involving submaximal voluntary contractions were applied. Sex differences in absolute and normalized amplitude of sEMG were analyzed. The normalization method had a significant influence on the observed sex differences. Females only showed higher sEMG amplitude than males when the sEMGs were normalized to MVC and to a submaximal contraction based on 20% of MVC for the upper trapezius (acromial fibers). Researchers and practitioners should be aware of the impact of the sEMG normalization method in sex differences investigation.

Adding Handles to Optimize Manual Box Handling.

The risk factors for developing musculoskeletal disorders in material handling tasks are well known. Among strategies for controlling risks, modifying boxes by adding handles is suggested. However, there are no clear recommendations regarding box modification as an approach to improve musculoskeletal health. In this study, we investigated the main literature databases to identify effects of box modification on reducing physical load. Electronic and manual searches were performed to identify studies that evaluated effects of boxes handles on physical exposure during handling tasks. The included studies were very heterogeneous (methods of assessment, types of handles used, and methodological quality), jeopardizing synthesis of evidence. Despite the mentioned limitations, we could suggest some features that could improve manual handling in practical settings, like the use of cylindrical handles forms with intermediate diameters (between 31 and 51 mm) and 30° inclination. Those characteristics demonstrated positive results on physical exposure. Regular cut-outs were indicated as a beneficial approach when boxes are handled in high surfaces. When handling occurs in medium heights or in the floor level, handles positioned on the top of the box might bring better results. Efforts to standardize methods are important to support both objective and subjective assessment of box handle design, as well to improve the internal validity of studies.

Comparison of muscle activity from upper trapezius and wrist extensors between dominant and non-dominant upper limbs during computer-based tasks.

BACKGROUND: Sustained low-level muscle activity occurring during computer-based tasks is associated with the development of WMSDs (work-related musculoskeletal disorders) and this biomechanical exposure may be different between limbs. OBJECTIVE: To compare muscle activity from dominant and non-dominant upper trapezius (UT) and wrist extensors (WE) during computer-based tasks in real work settings. METHODS: Forty-five workers were monitored during two hours while performing their usual administrative tasks. Surface electromyography (sEMG) was recorded from UT and WE muscles in both sides. Rest and general exposure variables were calculated. RESULTS: The 50th percentile demonstrated little muscle activity demand, for both dominant and non-dominant UT and no difference between sides was observed. The dominant WE muscles had lower measures of rest and higher muscle activity when compared with the non-dominant side. CONCLUSIONS: Differences in sEMG between upper limbs were only found in WE muscles, probably due to the use of the mouse. The overall low-level muscle activity suggests a constant activation of the same motor units for the entire data-collection period, which can be considered harmful for musculoskeletal health.

Effects of active pause pattern of surface electromyographic activity among subjects performing monotonous tasks: A systematic review.

Active pauses have shown potentially beneficial effects to increase the variability of the electrical activation pattern of muscles. However, there is a lack of consensus as to how to design and implement those pauses and the processing methods of surface electromyography (EMG) data when evaluating low-level monotonous tasks. The aim of this systematic review was to synthesize the evidences regarding the way which active pauses have been applied, and the methods used to investigate the related EMG changes. PubMed-MEDLINE, Embase, Web of Science, Lilacs, Ebsco, and Scopus databases were searched. Two authors independently extracted data from the primary studies. The methodological quality was assessed using a list from van der Windt et al. (2000), and the level of evidence was synthesized through GRADE. The ISEK guideline for reporting EMG data was also applied as a checklist. Fifteen studies were included - 14 with high methodological quality. In general, active pauses were able to change the level of EMG activity in monotonous tasks. The level of evidence through GRADE was very low for all EMG processing methods, except RMS which was low. A vast heterogeneity concerning the methods applied to analyze EMG data contributed to decrease the quality of evidence synthesis, and the findings need to be carefully considered. The GRADE approach and the ISEK guideline contributed to identify important flaws in the literature. Future studies investigating active pauses in longitudinal studies and following the standard for recording and reporting EMG data care are warranted.

Effects of a muscular stretching and strengthening school-based exercise program on posture, trunk mobility, and musculoskeletal pain among elementary schoolchildren - a randomized controlled trial / Efeitos de um programa escolar de exercícios de alongamento e fortalecimento muscular sobre a postura, mobilidade do tronco e dor musculoesquelética em escolares do ensino fundamental - ensaio clínico randomizado controlado / Efectos de un programa escolar de ejercicios de estiramiento y fortalecimiento muscular sobre la postura, movilidad del tronco y dolor musculoesquelético en escolares de la enseñanza fundamental - ensayo clínico randomizado controlado

Abstract Introduction: The exercise benefits for the most prevalent postural changes require proper investigation, with large samples, control group, and concealed allocation. Objective: To assess the effects of a muscular stretching and strengthening school-based exercise program on posture, trunk mobility, and musculoskeletal pain among elementary schoolchildren. Method: Three hundred students from three schools in Brazil were evaluated. Stretching and strengthening exercises, twice a week, for eight weeks in group sessions were provided by one physiotherapist. The control group did not undergo any intervention. Head, back and shoulder posture were qualitatively evaluated. Head and trunk alignment were evaluated using the Posture Assessment Software. Cervical, thoracic, low back and upper limb pain were assessed for the last seven days. The trunk mobility was recorded through the flexibility of the posterior chain. Posture, pain and trunk mobility were recorded at baseline and after the intervention. Groups were compared using χ2 test, two-way MANOVA, and two-way ANOVA, with α set at 5%. Results: Shoulder posture showed significant results (P = 0.04), the intervention group showed the lower worsening rate. In the quantitative evaluation, a statistically significant difference was observed between assessments (P < 0.01 for head and trunk; ES = 0.53) but not between groups. The intervention group had a higher percentage of improvement in the overall musculoskeletal pain (P = 0.04; ES = 0.54). Mobility decreased an average of 1.8° in the control group and increased 5.0° in the intervention group, without statistical significance. Conclusion: The program was effective in reducing pain level and shoulder misalignment at the intervention group.

Prevalence of postural deviations and associated factors in children and adolescents: a cross-sectional study / Prevalência de variações posturais e fatores associados em crianças e adolescentes: um estudo transversal

Abstract Introduction: Postural deviations are frequent in childhood and may cause pain and functional impairment. Previously, only a few studies have examined the association between body posture and intrinsic and extrinsic factors. Objective: To assess the prevalence of postural changes in school children, and to determine, using multiple logistic regression analysis, whether factors such as age, gender, BMI, handedness and physical activity might explain these deviations. Methods: The posture of 288 students was assessed by observation. Subjects were aged between 6 and 15 years, 59.4% (n = 171) of which were female. The mean age was 10.6 (± 2.4) years. Mean body weight was 38.6 (± 12.7) kg and mean height was 1.5 (± 0.1) m. A digital scale, a tapeline, a plumb line and standardized forms were used to collect data. The data were analyzed descriptively using the chi-square test and logistic regression analysis (significance level of 5%). Results: We found the following deviations to be prevalent among schoolchildren: forward head posture, 53.5%, shoulder elevation, 74.3%, asymmetry of the iliac crests, 51.7%, valgus knees, 43.1%, thoracic hyperkyphosis, 30.2%, lumbar hyperlordosis, 37.2% and winged shoulder blades, 66.3%. The associated factors were age, gender, BMI and physical activity. Discussion: There was a high prevalence of postural deviations and the intrinsic and extrinsic factors partially explain the postural deviations. Conclusion: These findings contribute to the understanding of how and why these deviations develop, and to the implementation of preventive and rehabilitation programs, given that some of the associated factors are modifiable.

Resumo Introdução: Variações posturais são frequentes na infância e podem causar dor e prejuízo funcional. Embora a prevalência de variações posturais em crianças já tenha sido avaliada, poucos autores investigaram a associação entre a postura e fatores intrínsecos e extrínsecos. Objetivo: Avaliar a prevalência de variações posturais em crianças e adolescentes e identificar fatores explicativos para estas variações, dentre eles: idade, gênero, dominância manual, índice de massa corporal (IMC) e atividade física, por meio da análise de regressão logística múltipla. Métodos: A postura de 288 estudantes foi avaliada de forma observacional. Os sujeitos tinham idades entre 6 a 15 anos, sendo 171 (59,4%) do sexo feminino. A idade média foi de 10,6 (2,4) anos, massa corporal de 38,6 (12,7) kg e altura de 1,5 (0,1) m. Utilizou-se balança digital, fita métrica, fio de prumo e formulários padronizados. Os dados foram analisados descritivamente, com o teste de Qui-quadrado e regressão logística (nível de significância - 5%). Resultados: A prevalência de anteriorização da cabeça foi de 53,5%; elevação do ombro 74,3%; assimetria entre as cristas ilíacas 51,7%; joelhos valgos 43,1%; hipercifose torácica 30,2%; hiperlordose lombar 37,2% e 66,3% de escápulas aladas. Os fatores associados foram idade, sexo, IMC e não realização de atividade física. Discussão: A prevalência de variações posturais foi alta. Os fatores escolhidos explicam parcialmente as variações posturais. Conclusão: Esses achados contribuem para a compreensão do desenvolvimento destas variações e para a proposição de programas preventivos e de reabilitação, considerando que entre os fatores analisados, alguns são modificáveis.

A biomecânica e a produção do conhecimento em fisioterapia: levantamento baseado nos anais do congresso brasileiro de biomecânica / The biomechanics and the production of knowledge in physiotherapy: survey based on the proceedings of Brazilian congress of biomechanics

O aumento gradual da participação da comunidade acadêmica da Fisioterapia nas edições do Congresso Brasileiro de Biomecânica (CBB) é notório. Os Anais do CBB passaram a ser importantes veículos para a divulgação científica em Fisioterapia no Brasil; porém, a caracterização dessa produção ainda não foi feita. O objetivo do presente estudo foi realizar um levantamento bibliográfico dos estudos em Fisioterapia publicados nas edições dos Anais do CBB, desde a primeira edição em 1992 (Anais do IV CBB) até a edição publicada em 2009 (Anais do XIII CBB), a fim de identificar quais especialidades da Fisioterapia têm aplicado o conhecimento em Biomecânica no contexto clínico e/ou científico, além de caracterizar o tipo de pesquisa que se tem desenvolvido. Seis revisores independentes levantaram os estudos pertencentes à área da Fisioterapia e coletaram informações de maneira padronizada através de questionários. Os resultados evidenciaram um grande crescimento da participação das diferentes áreas da Fisioterapia ao longo das dez edições do CBB. Embora os dados sejam positivos em relação à ampliação das pesquisas em Biomecânica, verificou-se uma carência da utilização dos recursos biomecânicos para avaliar efeitos de intervenções em pacientes. Dessa forma, recomenda-se que mais estudos sejam conduzidos em contextos clínicos e com acompanhamento longitudinal, de modo a ampliar a aplicação prática das ferramentas biomecânicas no campo da intervenção, bem como aperfeiçoar a avaliação em Fisioterapia.

The increasing presence of the Physical Therapy (PT) community in the Brazilian Congress of Biomechanics (CBB) is well known. The Proceedings of the CBB Congresses have turned to important vehicles to scientific publications in Physical Therapy, but the characteristics of these studies have not been focus of analysis. Thus, the purpose of this study was to identify the contribution of PT to the studies published in the Proceedings of the CBB Congresses, from the first edition in 1992 (Proceedings of the IV CBB) to the 2009 edition (Proceedings of the XIII CBB), in order to verify which subareas of expertise in PT are applying the biomechanical knowledge on clinical and/or scientific context and the kind of research being developed. Six independent reviewers collected data related to the PT production according to standardized questionnaires. The results evidenced that the area of PT has increased its publications along the ten CBB Proceedings. Despite positive findings, we noticed a lack of biomechanical studies aimed at investigating interventions in patients. Thus, we can suggest that clinical studies with a longitudinal design could be developed in order to improve the application of biomechanical tools in therapeutic settings and to contribute to evaluation procedures in PT.
