title: Functional exercise capacity evaluation in an aquatic environment

description: ABSTRACT The aim of this study was to investigate the correlation between distance achieved and compare the average speed while walking in the six-minute walk test (6MWT) performed on solid ground and in the three-minute walk test in water (3MWT-W) with healthy young individuals, as well as compare physiological (heart rate, oxygen saturation and blood pressure) and symptomatic variables between tests. It is a cross-sectional study, with a sample of 20 healthy young subjects. All patients underwent spirometry, answered a questionnaire on health and physical activity, in addition to performing the 6MWT and 3MWT-W. Statistical analysis used the Shapiro-Wilk test to evaluate normality of the data, the paired Student's t-test and Wilcoxon in the comparisons between the variables and the Pearson correlation coefficient to verify associations. Statistical significance of p &lt; 0.05 was adopted. The mean age was 22 (±2) years, the mean BMI was 23 (±3) kg/m2 and all subjects had normal pulmonary function. The average distance achieved in the 6MWT was of 657 (±43) meters and in the 3MWT-W of 135 (±13) meters. A weak correlation between the 3MWT-W and 6MWT (r=0.35) was found. The speed during the tests showed a statistically significant difference (3MWT-W 0.75±0.07 versus 6MWT 1.85±9.1, p&lt;0.0001). There was no difference in the initial and the final physiological variables between 3MWT-W and 6MWT. The 3MWT-W may be a good tool for evaluation and exercise prescription in the aquatic environment, but showed a weak correlation with the 6MWT and similar physiological strain, though further studies are suggested to confirm this finding.

title: Time performance and CoP displacement of hemiplegic subjects in a virtual reality game task: short and long-term effects of a training protocol

description: ABSTRACT Video games with virtual interaction have been successfully used in physical therapy programs, although there is a lack of knowledge regarding evidence involving clinical results. This study aimed to evaluate learning and some parameters of the center of pressure (COP) displacement of a Nintendo Wii Fit task in hemiplegic and healthy subjects immediately after a rehabilitation training program and after a 3-month washout period. Twenty subjects being 10 hemiplegic and 10 healthy performed three assessments over different periods; Pre, Post and 3-months after rehabilitation training. Participants were positioned on the Wii Balance Board(r). The game task performed (Ski Slalom(r) game) involved mediolateral movements. During the task's execution, the Wii Balance Board(r) was placed on a force plate (AMTI OR-6, USA). As such, COP data displacement could be collected during the game. After the training, the hemiplegic subjects showed no change in COP sway pattern and this condition persisted after three months. However, both groups improved their time performance to finish the task after training and maintained the improvement in performance after 3-months. COP displacement of hemiplegic subjects did not change after training, healthy subjects were able to reduce their mediolateral and anteroposterior COP displacement.

title: Comparison of postural balance among groups of women with different age ranges

description: ABSTRACT Aging impairs the ability of the central nervous system (CNS) to perform the processing of signals from the sensory systems, which are responsible for maintaining the body balance, reducing the capacity of modifying adaptive reflexes. This study aimed to compare the postural balance among women of different age ranges. A total of 60 women participated in the study: 20 from the young group (YG), 20 from the adult group (AG) and 20 from the elderly group (EG). Center of pressure (COP) data were collected using a force plate AMTI OR6-6. The variables analyzed were the range of anteroposterior (COPap) and medial-lateral (COPml) displacement of COP. Three tries with eyes open (EO) and three tries with eyes closed (EC), lasting 30 seconds for each one, were performed. The results show statistically significant differences in COPml with EO between YG and EG (p=0.10). No statistically significant differences were found in the COPap variable. We conclude that there is an increased postural sway in the elderly in this study compared to young women.

title: Reliability and validity of a load cell device for hand grip strength assessment

description: ABSTRACT The grip strength is a complex measure influenced by factors such as gender, age, motivation, muscle training, handedness, height, weight, socioeconomic variables, and participation in specific sports or professions. It can be measured by dynamometers or by tension meters such as load cells (strain gauges). Reliability and validity are important psychometric properties, which analyze consistency and applicability of an instruments' measurement. Thus, the aim of this study was to evaluate the test-retest reliability and construct validity of a load cell device in isometric grip force measurements using a sample of asymptomatic subjects and patients with wrist and hand dysfunctions. Standardized methods of the upper limb positioning and randomization of the sample order were used. Statistical analysis of reliability was conducted by the ICC (Intraclass Correlation Coefficient) and the construct validity by Pearson correlation coefficient (r), with p&lt;0.05, 95% CI, using SPSS version 20(r). The sample consisted of 24 healthy volunteers with an average age of 22.25 years old, all college students, and 21 volunteers with upper extremity and hand disorders, from both genders. The test-retest reliability for the asymptomatic group was ICC 0.90 (0.78-0.95) and for the group of patients was 0.94 (0.87-0.97), both considered excellent. The Bland and Altman graphics showed that although the reliability has displayed excellent levels and low standard error values of measurement, some discrepant data were found. Pearson correlation coefficients were high, both for the asymptomatic group (r=0.85), and for the patients group (r=0.83). Conclusion: based on these findings, it is suggested that this load cell is a reliable and valid device for isometric grip strength measurement and its use is suitable for future clinical trials and practice.

title: Effect of eight-point binding in static balance and distribution of plantar pressure after stroke

description: ABSTRACT The equinovarus foot is a common sequela after a cerebrovascular accident (CVA), the biomechanical changes of hemiparetic ankle interfere in balance and body asymmetry after a stroke. Several resources are used to minimize these changes, among them stands out the eight-point binding, which aims to provide proprioceptive information and promote the biomechanical alignment of the ankle, thus acting against the mechanisms leading to equinovarus foot. However, there is still no evidence of the effect of eight-point binding in static balance and plantar pressure distribution of the hemiparetic ankle. Thus, the aim of this study was to evaluate the immediate effect of eight-point binding on static balance and plantar pressure distribution in patients with hemiparesis due to stroke. To this end, we evaluated 30 subjects with chronic hemiparesis who were evaluated at three different times: without bandaging, with bandaging, and after five minutes of use of bandaging. The subjects were positioned on a force platform to assess balance and plantar pressure. For data analysis we used ANOVA for repeated measures, assuming α≤0.05 risk. There was no statistically significant difference in static balance and plantar pressure distribution after the use of eight-point binding in any of the evaluated moments in this study. It follows that a single application of the eight-point binding is not able to generate clinical changes in static balance and plantar distribution. It is suggested that further studies need to be conducted to examine the effect of prolonged use of eight-point binding.

title: Laser therapy, used in a specific dose, modulates pulmonary inflammatory processes in an experimental model of sepsis in rats

description: ABSTRACT This study aimed to determine the effectiveness of LLLT in decreasing the lung inflammatory process in septic rats. A total of 32 male Wistar rats were divided into four groups (n=8): control group (CG), sepsis 24h (S24), sepsis and LLLT with 30 J/cm² (S24L30); sepsis and LLLT with 65 J/cm² (S24L65). The irradiation was performed immediately after surgery in the anterior region of the trachea and ventral regions of the chest, bilaterally, just below the ribs. Histological analysis of lung tissue was performed and the number of inflammatory cells was quantified. The S24 group showed an increase of inflammatory cells compared to the CG (p &lt;0.01); S24L30 increased the number of inflammatory cells, while S24L65 decreased this number compared to S24 (both p&lt;0.05); S24L65 had a lower number of inflammatory cells compared to S24L30 (p&lt;0.01). In conclusion, LLLT at a specific energy dose (30J / cm²) was capable of decreasing the number of inflammatory cells in acute lung tissue inflammation due to sepsis.

title: Coactivation and peak torque of extensors and flexors knee muscle in chronic hemiparetics in sitting and supine positions

description: ABSTRACT Disorders in co-activation and decreased muscle strength are often described in hemiparetic subjects. Changes in muscle length resulting from postural change may result in different responses of co-activation and strength of these individuals. The objective of this study was to evaluate the influence of sitting and supine positions in Co-activation Index (CI) and peak torque (PT) of chronic hemiparetic subjects after stroke. The participants were twenty individuals with mean age of 54±12.14 years; mean body mass index of 26.93±3.34 kg/m²; average stroke time of 55.85±49.4 months; Mini-Mental State Examination score between 27-30; and Fugl-Meyer of lower limb between 15-30. The electromyographic record was obtained while the volunteers performed five isokinetic contractions (60º/s) of knee extension and flexion in the sitting and supine positions. The semitendinosus muscle of paretic limb exhibited lower CI in the supine position compared to sitting: 0.36±0.33; 0.44±0.33 (p=0.048). There was no difference in CI of the rectus femoris between positions: 0.28±0.25 sitting and 0.23±0.21 supine. The PT of extensor and flexor muscles of the paretic limb did not vary between positions (PT extensor: sitting = 56.48±37.62 Nm, supine = 52.29±32.37 Nm; PT flexor: sitting = 12±11.1 Nm, supine = 10.95±6.4 Nm). The supine position showed lower CI in the semitendinosus muscle of paretic limb. The change of position did not influence the CI of rectus femoris muscle neither the PT of both muscle groups of the paretic limb. Thus, the supine position appears to be indicated during movement and strength training of these muscles in chronic hemiparetic patients after stroke.

title: Effects of upper cervical manipulation on the electromyographic activity of the masticatory muscles and the opening range of motion of the mouth in women with temporomandibular disorder: randomized and blind clinical trial

description: ABSTRACT We evaluated the effects of upper cervical manipulation on the surface electromyographic activity (sEMG) of masticatory muscles and range of motion of the opening movement of the mouth in women with temporomandibular disorders (TMD). We evaluated 10 women with myogenic a TMD diagnosis, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and divided randomly into an experimental group (EG) n=5, which received upper cervical manipulation, and a placebo group (PG) n=5, which received maneuvers without therapeutic effects. Five interventions were performed in both groups, once a week, with performance of pre-intervention assessments, post-immediate assessments (after 1st intervention) and post-delayed assessments (48 hours after the 5th intervention). The sEMG activity was processed using the root mean square and normalized by the peak value (RMS EMGn). We used for comparison the Student's t-test and ANOVA two-way repeated measures, adopting as significance the amount of 5%, and the Cohen d for treatment effect size. We found a significant interaction of group vs time (p&lt;0.05) in the RMS EMGn of the left and right temporal muscles at rest, as well as for all masticatory muscles during maximal isometric contraction during jaw-elevation and jaw-depression. Treatment effect size, high to moderate, was observed in the EG, especially in the post-delayed assessment. We also observed a significant increase (p&lt;0.05) and a high treatment effect during mouth opening in the EG. The upper cervical manipulation demonstrated a balance of the RMS EMGn of the masticatory muscles and increase the opening range of motion of the mouth in women with myogenic TMD.

title: Sensory evaluation tools stroke described in Portuguese: a systematic review

description: ABSTRACT Most survivors of stroke present, among other consequences, a sensory deficit. To assess the impact of this deficit on the activity and the effect of sensory reeducation protocols, it is important to use objective instruments. The objective of this systematic review was to analyze which sensory evaluation tools for post-stroke patients are available in Brazilian Portuguese and describe its features and/or properties. A search was conducted in the electronic databases SCIELO, LILACS, PUBMED, CINAHL, MEDLINE via OVDI, and EMBASE. The relevant studies were analyzed as to accessibility, objectivity of the score and measurement properties, adding articles through manual search when necessary. The search resulted in 96 studies, reduced to five eligible ones. A study was added through the list of references and the manual search was used for complementation. Among the seven reviewed articles, only three sensory evaluation tools are available in Portuguese: moving touch pressure (MTP), sensitivity domain of Fugl-Meyer Scale (FMS), and Nottingham Sensory Assessment (NSA). In addition, although the reliability of the FMS and of the NSA may be considered appropriate, the other properties of measurement need to be evaluated in future studies.
