title: Association between peak oxygen consumption and six-minute walk test in patients after cardiac surgery

description: ABSTRACT Patients undergoing coronary artery bypass grafting (CABG) have reduced cardiorespiratory capacity after the procedure. An adequate assessment in the patients’ postoperative period is essential, aiming at a better prescription for cardiopulmonary rehabilitation phase II and return to daily life activities. Our study sought to evaluate the correlation between peak oxygen consumption (peak VO2), from cardiopulmonary exercise test (CPET) with the distance covered in the six-minute walk test (6MWT) in patients after 40 days of CABG. This is a cross-sectional study with sample consisting of patients submitted to CABG. Patients included were assessed 40 days after the surgery in a hospital environment through cardiopulmonary exercise test in a treadmill protocol and the 6MWT according to the American Thoracic Society. We used the Pearson’s correlation test to analyze the outcomes. Thirty-nine patients participated in the study, of which 28 (71.8%) were men, with a mean age of 58±years. It was possible to observe a sedentary lifestyle (74.4%), tobacco use (74.4%) and high prevalence of systemic arterial hypertension (82.1%). The mean distance walked on the 6MWT was 494m±70m and the mean peak VO2 was 19.5±3.6 mL/kg/min and the correlation between them was r=0.48; p=0.02. There was a moderate and statistically significant correlation between the distance walked in the 6MWT and the peak VO2 in patients after 40 days of CABG.

title: Psychometric properties of WHODAS for use in patients with chikungunya in Brazil

description: ABSTRACT The aim of this study is to validate an assessment tool for functioning and health according to the conceptual proposal of the International Classification of Functioning, Disability and Health (ICF), for its use in post-chikungunya patients. This is a validation study with individuals &gt;17 years old of both sexes. Data collection was performed through interviews, gathering information on functioning (WHODAS), quality of life (WHOQOL-bref) and socio-demographic data. Statistical analysis used the Cronbach alpha coefficient (internal consistency) and Spearman correlation coefficient (convergent validation), means and standard deviations, with significance level of 5%. The sample consisted of 68 individuals. The mean values of scores were: 45.4 (±16.38) for WHODAS and 12.1 (±2.10) for WHOQOL-bref. The Cronbach’s alpha of the total value was α=0.93; all WHODAS domains presented values ≥0.75. The total value of WHODAS 2.0 had strong correlation with the physical domain (r=−0.74) and moderate correlation with the psychological (r=−0.68) and social (r=−0.42) domains of the WHOQOL-bref. The results indicate that WHODAS 2.0 is a valid instrument for the measurement of self-perceived functioning alteration in patients affected by chikungunya.

title: Development and evaluation of physical properties of a low-cost handheld device for airway clearance therapy

description: ABSTRACT Several respiratory diseases are characterized by hypersecretion, requiring airway clearance therapy (ACT). Oral high-frequency oscillation (OHFO) devices are effective to enable daily ACT; however, they are still too expensive to become available for low-income patients. We sought to develop a low-cost device (OHFO-LC) and compare its physical properties with those OHFO commercially available (Shaker and Flutter). The OHFO-LC was developed from polyvinyl chloride material and one stainless steel sphere. Pressures and frequencies were measured at flows of 4, 6, 8, 10 and 15L/min. Pressures at the mouthpieces were measured by a transducer connected to a microcomputer. The oscillation frequencies were obtained from the graph of the pressure. The frequencies and pressures were compared among groups using one-way Anova and Tukey’s post hoc tests, p≤0.05. There were no differences among the frequencies of the three devices in all tested flows. The OHFO-LC device showed a higher positive expiratory pressure compared with the Shaker at all tested flows (4 L/min: 4.7±1.2 vs. 1.0±0.2 cmH2O; 6 L/min: 8.6±1.5 vs. 3.5±0.5 cmH2O; 8 L/min: 10.8±1.6 vs. 5.4±0.2 cmH2O; 10 L/min: 13.5±1.2 vs. 7.7±0.4 cmH2O; 15 L/min: 14.3±1.1 vs. 7.8±0.2 cmH2O; OHFO-LC vs. Shaker; p≤0.05) and at 10 and 15 L/min compared with Flutter (10 L/min: 13.5±1.2 vs. 7.5±1.2 cmH2O; 15 L/min: 14.3±1.1 vs. 8.2±1.2 cmH2O; OHFO-LC vs. Flutter, p≤0.05). The cost of the OHFO-LC device was much lower than both the Shaker and the Flutter. Our results showed that the OHFO-LC had physical properties with similar frequencies but higher pressures than other OHFO devices that are commercially available. Future studies are necessary to evaluate its clinical efficacy.

title: Comparison of perceived disability and functional independence in individuals with spinal cord injury athletes and non-athletes

description: ABSTRACT Functional impairment in individuals with spinal cord injury (SCI) generate secondary complications, with preponderant physical deconditioning and an exacerbation of injury complications. The objective was to evaluate the perceived disability and functional independence in athletes and non-athletes with SCI. The WHODAS 2.0 and SCIM III questionnaires were applied to 37 volunteers with SCI and their sociodemographic data were collected. The total scores of WHODAS 2.0 and SCIM III of individuals with thoracic SCI and cervical SCI were compared using the Mann-Whitney test. Regarding the perceived disability, a significant difference was found in WHODAS 2.0 among athletes and non-athletes with thoracic SCI. As to functional independence, no significant differences were found between groups in SCIM III. Although the sports practice promotes health benefits, no significant differences were found in the group of individuals with cervical SCI, which can be explained by these individual’s higher degree of motor impairment.

title: Identification of risk factors for falls in people with multiple sclerosis: a systematic review of prospective studies

description: ABSTRACT The objective of this study was to identify demographic, clinical, and instrumental variables associated with falls in people with multiple sclerosis (MS), via systematic review, based on prospective data. The search was conducted in these databases: Medline, Web of Science, Bireme e CINAHL via a search strategy that combined the descriptors “multiple sclerosis”, “falls”, “accidental falls”, “fall risk”, “postural control” and “balance”, followed by manual search. Eligibility criteria were prospective cohort studies with a minimum 3-month follow-up of falls that assessed the association of a demographic, clinical or instrumental variable in relation to a higher fall risk in people with MS. The modified Newcastle-Ottawa Quality Assessment Scale was used for study quality assessment. A total of 357 studies were identified, of which 12 were included in the systematic review and 1,270 patients were included. In this study, 740 (58.26%) patients were classified as fallers, 396 (31.18%) patients had recurrent falls (2≥falls within the stipulated period) and 530 patients (41.74%) were classified as non-fallers. Except for spasticity and dual task cost in gait speed, all investigated variables showed conflicting results regarding their association with a higher fall risk. More studies with clinical homogeneity phenotypes of MS individuals and using validated assessment instruments are necessary to establish a robust association of other clinical, instrumental, and demographic variables with a higher fall risk.

title: Analysis of static postural balance and of intensity of musculoskeletal pains after the use of proprioceptive insoles by ostensive service militaries

description: ABSTRACT To maintain the balance, the body uses visual, vestibular and proprioceptive systems, which send information to the central nervous system about the body’s conditions in order to stabilize it. This study evaluated the effect of proprioceptive insoles on static postural balance and musculoskeletal pains after two months of use, through a longitudinal analytical study with 15 healthy male soldiers with a mean age of 34±7.5 years. They were subjected to balance evaluation through the Medicapteurs® platform and by CNT protocol. There was no statistical difference for the deviations of the body and speed of the center of pressure. Plantar pressure had a statistically significant change for the left and the right feet, corresponding to p=0.0001 and p=0.0007, respectively. There was a reduction in the mean values of the pains in the knees, feet and heels and a significant decrease in lumbar spine pain, with p=0.0180. The static balance was not significantly altered with the use of proprioceptive insoles by the militaries; however, these insoles provided a better redistribution of plantar pressures and seem to attenuate the musculoskeletal pains of the lower extremities. Therefore, insoles can be considered as a prevention therapy against injuries for this group related to their work activity.

title: Mean values for the 6-minute walk test in healthy children of Coari (AM), Brazil

description: ABSTRACT The objective of this research was to establish mean values covered for the six-minute walk test in healthy children in Northern Brazil. This was an experimental, randomized, blind and cross-sectional study that evaluated 63 healthy male and female children, aged 10 to 12 years, who after having their anthropometric data recorded were trained and instructed to perform the test as recommended by the American Thoracic Society, after standard assessment. The test was carried out on a straight track of 30 meters, with markings every 3 meters and cones indicating where the return should be made for the test continuity. At the end, the pre-test evaluation was redone. Very low body mass index was observed in 11-year-old boys, and normal in other age groups. The post-test immediate heart rate was significantly elevated in all groups (p&lt;0.001), while all other cardiovascular data collected did not change. The distances covered were significantly lower than those predicted by the standard equation for all groups and sexes (p&lt;0.0001). The average value found in girls was 436.30±56.74m and 460.80±63.90m in boys, while the general average was 445.70±54.10m, below the expected values for the sample. The result obtained by the studied group, less than the expected average, can be credited to the regional phenotype, but the Development Index much lower than the Brazilian average should have its influence better studied. The findings are expected to contribute to the establishment of reference values for the test in children from northern Brazil.

title: The influence of medium longitudinal arch on plant distribution and posterior pliability

description: ABSTRACT Objective: To evaluate whether the formation of the longitudinal arch of the foot interferes with the distribution of plantar pressure and the pliability of the posterior thigh muscles. Methodology: a cross-sectional study and the footprints were obtained using the footprinting mat and analyzed according to the Viladot method. Plantar distribution and pliability were assessed by baropodometry and Wells’ bank, respectively. Results: It was observed that children with cavus feet present greater pliability when compared to those with normal feet (p=0.02). Also, the cavus feet exhibit higher pressure, that is, a greater heel overload compared to those with normal plantar arch (p=0.02 lower right limb and p=0.03 lower left limb). Conclusions: The evaluation of the medial longitudinal arch shows that children with cavus feet have greater pliability of the lower limb posterior muscles. The cavus feet are also associated with higher pressure in the calcaneal region.

title: Musculoskeletal disorders, stress perception and physical activity in police officers

description: ABSTRACT The purpose of this study is to analyze association between stress perception and physical activity with the prevalence of symptoms of musculoskeletal disorders (SMSD) in police officers. The police officers (n=142) answered the Perceived Stress Scale-10 (PSS-10) and the Nordic Musculoskeletal Questionnaire. Pearson’s linear correlation coefficient was used to measure strength and direction of relationship between PSS-10 and prevalence of SMSD and showed a positive correlation between variables in the last 7 days (r=0.34, p=0.00001) and in the last 12 months (r=0.40, p=0.00001). The mean prevalence of SMSD in the last 12 months was lower among police officers practicing physical activity (W=1888.5, p=0.04). Multiple logistic regression analysis showed that the practice of physical activities as well as efforts to reduce stress perception both decrease the odds of musculoskeletal disorders. This study indicated that stress level and physical activity practice influenced in prevalence of SMSD. Multidisciplinary interventions with actions to reduce stress level and encourage physical activity practice are needed to control SMSD prevalence.
