The Effectiveness of Ischemic Compression Technique on Pain and Function in Individuals With Shoulder Pain: A Systematic Review.

OBJECTIVE: To systematically review current literature to determine the effectiveness of the ischemic compression (IC) technique on pain and function in individuals with shoulder pain. METHODS: This review was conducted according to recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Collaboration for Systematic Reviews; a search was performed in the electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, Physiotherapy Evidence Database, and Web of Science. Randomized clinical trials and quasi-randomized clinical trials were included, and the methodological quality was evaluated through the Physiotherapy Evidence Database scale. RESULTS: The search found 572 studies; of these, 71 were selected by title and, subsequently, 29 were selected through abstract analyses. After critical analyses, 5 studies were included. The methodological quality ranged from 4 (reasonable) to 9 (excellent) points. Pain was assessed by all studies using the visual analog scale, Global Perceived Effect scale, Numerical Rating Scale, pressure pain threshold, or Perceived Amelioration Numerical Scale. Function was evaluated by 3 studies through the Shoulder Pain and Disability Index; Neck Disability Index; American Shoulder and Elbow Surgeons Standardized Shoulder Assessment; and Disabilities of the Arm, Shoulder, and Hand questionnaires. The studies showed that the IC technique produces immediate and short-term positive effects for pain, and positive short-term effects for shoulder function in individuals with shoulder pain. CONCLUSION: The IC technique seems to be beneficial for pain and shoulder function. However, caution is needed when considering this evidence owing to the limited quality of some studies, the few articles found, and the lack of standardization of the application parameters of the technique to facilitate its reproducibility.

Influence of a periodized circuit training protocol on intermuscular adipose tissue of patients with knee osteoarthritis: protocol for a randomized controlled trial.

BACKGROUND: The objective of this study is to analyze the influence of a 14-week periodized circuit training protocol on patients with knee osteoarthritis (OA), in randomized intervention groups, on thigh intermuscular adipose tissue (interMAT), body composition, systemic inflammation, cartilage degradation, and its repercussion on pain, functional performance and quality of life. METHODS: This study presents a protocol for a randomized controlled trial. Sixty selected participants diagnosed with knee OA grades II and III, 40-65 years old and BMI < 30 kg/m2, will be randomly divided into three groups:periodized circuit training, strength training, and educational protocol. The circuit training and strength training protocols consist of 14-week training protocols conducted 3 times a week. The circuit training group will perform selected exercises previously stratified as light, moderate, and intense, arranged progressively in a circuit model, the strength group will perform regular strength exercises, and the educational protocol group will participate in a 14-week protocol with lectures twice a month about healthy lifestyles. Baseline and follow-up evaluations will be conducted for thigh interMAT (computed tomography), body composition (DXA), inflammation (IL-1ß, IL-6, IL-10, TNF-α, leptin, and adiponectin), and joint degradation biomarkers (uCTX-II and sCOMP), performance-based tests (30s Chair Stand Test, 40 m Fast-paced Walk Test and Stair Climb Test), quadriceps and hamstring maximal isometric voluntary contraction (MIVC), and questionnaires (WOMAC and pain catastrophizing scale). Repeated measures ANOVA will be used to compare differences between groups (circuit training X strength training X educational protocol) at the different times of assessment (baseline x follow-up or baseline x during protocol x follow-up) for each of the dependent variables. When significant main effects were found, the pots hoc Bonferroni test will be used to identify statistical differences. A significance level of 5% (p < 0.05) will be adopted. DISCUSSION: This will be the first randomized controlled trial to assess the effects of a circuit training protocol on patients with knee OA on thigh intermuscular adipose tissue (interMAT). Given the prevalence and impact of OA and the widespread availability of this intervention, assessing the efficacy of a low-cost, non-pharmacological, and non-invasive treatment for knee OA patients has the potential for immediate and high clinical impact.

Activity limitations in leprosy and their association to cognition and neuropsychiatric symptoms.

OBJECTIVES: to analyze activity limitations in patients with leprosy and their association to cognition and neuropsychiatric symptoms. METHODS: this cross-sectional design study included sixty patients with multibacillary leprosy assisted at a reference center. Participants were divided according to their physical disability and submitted to instruments assessing daily activities (basic and instrumental), cognitive functions, and neuropsychiatric symptoms. The order of the instruments was random to avoid any interference of test sequence on the results. RESULTS: fifty-five percent of the participants presented physical disabilities. All patients were independent in performing basic activities but sixty-six percent presented difficulties in performing instrumental activities. Cognitive decline and neuropsychiatric symptoms were seen in advanced stages of the disease, but they were more associated to patient age than to leprosy. CONCLUSIONS: leprosy patients presented physical disabilities and difficulties in performing instrumental daily activities. Cognitive decline and neuropsychiatric symptoms were more associated to aging than to leprosy itself.

Reductions of cardiovascular and metabolic risk factors after a 14-week periodized training model in patients with knee osteoarthritis: a randomized controlled trial.

INTRODUCTION/OBJECTIVE: To evaluate the effects of a periodized circuit training (CT) compared with a conventional strength training (ST) and an educational protocol (EP) on body composition, metabolic parameters, muscle strength, pain, and physical performance in patients with knee osteoarthritis (KOA). METHOD: This study followed a randomized controlled trial design. A sample of sixty-one patients with KOA, 40-65 years old and BMI < 30 kg/m2, were randomly divided into three 14-week protocols: CT, ST, or EP. The CT performed whole body exercises organized in circuit, 3 times a week. The ST performed conventional resistance exercises also 3 times a week, and the EP joined in educational meetings twice a month. Body composition (dual-energy X-ray absorptiometry (DXA)); metabolic parameters (abdominal obesity, triglyceride, HDL, blood pressure and fasting glucose), knee maximal isometric voluntary contraction (MIVC) extension and flexion, performance-based tests (40-m walk test, 30-s chair test, and stair climb test), self-reported pain, stiffness, and physical function (WOMAC) and pain catastrophism were evaluated at baseline and follow-up. Repeated measures ANOVA were used to compare differences between groups (CTxSTxEP) at the different times of assessment (baseline × follow-up). When group-time interaction was found, a one-way ANOVA, followed by a Bonferroni post hoc test, was used to compare groups in each time point; while a paired t test was used to verify the time effect in each group. Additionally, the training effect was analyzed in terms of the percent change (Δ%). Effect size was calculated for post intervention (week 14) between groups. For all analyses a significance level of 5% was adopted (p < 0.05). RESULTS: The CT was the only protocol that presented significant lower body mass (p = 0.018; Δ% = - 1.4), fat mass (p = 0.017; Δ% = - 10.3), %fat mass (p < 0.001; Δ% = - 13.9), adipose indices (%fat trunk/%fat legs p = 0.031; Δ% = 7.8; fat mass/height2 p = 0.011; Δ% = - 15.1; trunk/limb fat mass p = 0.012; Δ% = - 8.2; visceral adipose tissue (VAT) volume (cm3) p = 0.039; Δ% = - 11.6; VAT area (cm2) p = 0.044; Δ% = - 12.2), blood pressure levels (SBP p = 0.042; Δ% = - 3.4 and DBP p = 0.001; Δ% = - 4.9), higher lean mass and HDL (p < 0.001; Δ% = 5.9) compared to baseline. CT and ST presented lower WOMAC pain, stiffness and physical function (p < 0.001; Δ% = - 64.0 for CT and p < 0.001; Δ% = 0.001; Δ% = - 46.4 for ST in WOMAC total score, pain catastrophizing (p < 0.001; Δ% = - 66.7 for CT and p < 0.001; Δ% = - 61.5 for ST) a higher functional performance (30 s chair test: p < 0.001; Δ% = 45.7 for CT and p < 0.001; Δ% = 26.9 for ST; 40 m walk test: p < 0.001; Δ% = 26.7 for CT and p < 0.001; Δ% = 12.5 for ST; stair climb test: p = 0.002; Δ% = - 33.9 for CT and p < 0.001; Δ% = - 18.8 for ST) and knee extension MIVC (p < 0.001; Δ% = 21.92 for CT and p < 0.001; Δ% = 30.25 for ST). CONCLUSION: A periodized CT model reduces visceral adipose tissue, SBP and DBP, and improves HDL, important cardiovascular and metabolic risk factors, in patients with KOA. Both trained groups (CT and ST) improve self-reported clinical symptoms, muscle strength, and physical performance in this sample. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov , NCT02761590 (registered on May 4, 2016). KEY POINTS: • A 14-week periodized circuit training reduces visceral adipose tissue, systolic and diastolic blood pressure, and improves HDL blood levels in patients with knee osteoarthritis. • Both periodized circuit training and conventional strength training improve clinical symptoms, functional performance and muscle strength in this sample.

Effects of aquatic physical exercise on neuropsychological factors in older people: A systematic review.

BACKGROUND: . There is a lack of standardized protocols and clinical trials for older adults involving neuropsychological factors in the literature. Furthermore, no systematic review has been published investigating this theme. PURPOSE: . The purpose of this systematic review was to analyze the effects of aquatic physical exercise on neuropsychological factors in older adults. METHODS: . A systematic review (CRD42020176899) was conducted, using articles from Pubmed, Web of Science, Scopus, Cochrane Library, Science Direct and Medline published until March 2020 (without limit of previous year). Eligibility criteria for selecting studies were: clinical trials; samples with a mean age of 65 years old and over; articles involving aquatic physical exercise; and presenting neuropsychological outcomes (behavior, cognition, psychological, mental health). RESULTS AND DISCUSSION: . The search yielded 801 records and 16 studies were included, totaling: 1707 older adults, with a mean age of 71.3 years old (range of mean ages in the studies: 65.3 to 88.4 years old) and a predominance of women. Aquatic physical exercise showed positive results in the mental component of quality of life, fear of falling, mood, anxiety and internal health locus of control in healthy sedentary older adults. Only one study out of 5 carried out with older adults with osteoarthritis showed improvements in psychological well-being after aquatic intervention. Older women with osteopenia or osteoporosis showed improvements in the mental component of quality of life. Studies on dementia showed a significant improvement in behavioral and psychological symptoms after aquatic intervention and no effect on depressive symptoms. CONCLUSION: . Based on the results of this systematic review, aquatic physical exercise has positive effects on quality of life, fear of falling, cognitive functions, mood, anxiety and internal health locus of control in sedentary community-dwelling older people. It can be a great resource for carrying out physical activities in this population.

The relationship between urinary C-Telopeptide fragments of type II collagen, knee joint load, pain, and physical function in individuals with medial knee osteoarthritis.

OBJECTIVE: Considering the osteoarthritis (OA) model that integrates the biological, mechanical, and structural components of the disease, the present study aimed to investigate the association between urinary C-Telopeptide fragments of type II collagen (uCTX-II), knee joint moments, pain, and physical function in individuals with medial knee OA. METHODS: Twenty-five subjects radiographically diagnosed with knee OA were recruited. Participants were evaluated through three-dimensional gait analysis, uCTX-II level, the WOMAC pain and physical function scores, and the 40m walk test. The association between these variables was investigated using Pearson's product-moment correlation, followed by a hierarchical linear regression, controlled by OA severity and body mass index (BMI). RESULTS: No relationship was found between uCTX-II level and knee moments. A significant correlation between uCTX-II level and pain, physical function, and the 40m walk test was found. The hierarchical linear regression controlling for OA severity and BMI showed that uCTX-II level explained 9% of the WOMAC pain score, 27% of the WOMAC physical function score, and 7% of the 40m walk test. CONCLUSION: Greater uCTX-II level is associated with higher pain and reduced physical function and 40m walk test performance in individuals with medial knee OA.

A periodized training attenuates thigh intermuscular fat and improves muscle quality in patients with knee osteoarthritis: results from a randomized controlled trial.

OBJECTIVE: To analyze the influence of a 14-week periodized circuit training (CT) protocol on thigh intermuscular fat and muscle quality (force per unit area of lean tissue) in patients with knee osteoarthritis (KOA). DESIGN: Randomized controlled trial METHODS: Sixty-one selected participants with KOA grades 2 and 3, 40-65 years old, and BMI < 30 kg/m2 were randomized into three groups: CT, conventional strength training (ST), and educational protocol (EP). The CT and ST protocols consisted of 14-week training protocols conducted 3 times a week. The CT group performed exercises stratified as light, moderate, and intense, arranged progressively in a circuit model. The ST group performed conventional strength exercises, and the EP group participated in lectures twice a month about healthy lifestyles. Baseline and follow-up (week 0 and week 14) evaluations were conducted for thigh intermuscular fat (computed tomography), knee extension maximal isometric voluntary contraction (MIVC), and muscle quality (knee extension MIVC/muscle mass cross-sectional area). RESULTS: Only the CT group presented significant reductions in thigh intermuscular fat (p = 0.003) and significantly lower values in week 14 compared with the EP (p = 0.032). Both trained groups presented significant increases in muscle mass area (p=0.002 for CT and p=0.008 for ST) and increments in knee extension MIVC (p=0,033 for CT nd p=0.019 for ST) in week 14 compared with the EP and increases in muscle quality (p = 0.004 and 0.042). CONCLUSION: It can be concluded that a 14-week periodized CT protocol attenuates thigh intermuscular fat and improves muscle quality in patients with KOA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02761590; https://clinicaltrials.gov/ct2/show/NCT02761590Key Points•Fourteen weeks of periodized circuit training attenuates thigh intermuscular fat in patients with knee osteoarthritis.•Circuit training is as effective as strength training for improving muscle mass, strength, and quality.

The role of hip abductor strength on the frontal plane of gait in subjects with medial knee osteoarthritis.

OBJECTIVE: This study aimed to investigate the relationship of hip abductor strength with external hip and knee adduction moments, pain and physical function, and trunk, pelvis, and hip kinematics in the frontal plane during walking in subjects with medial knee osteoarthritis. METHODS: Twenty-five subjects with medial knee osteoarthritis were evaluated through an isokinetic strength test for hip abductor, three-dimensional gait analysis (kinetics and kinematics), and pain and physical function scores. Regression models were used to control the influence of other parameters such as pain, age, gender, severity, walking speed, mass, and height. RESULTS: No relationship was found of hip abductor strength with peak of external knee adduction moment and knee adduction angular impulse. Hip abductor strength explained 17% of contralateral pelvic drop and 21% of hip adduction angle. In addition, hip abductor strength explained 4% and 1% of the variance in the WOMAC physical function score and 40-m fast paced walk test, respectively. CONCLUSION: Considering the relationship of hip abductor strength with contralateral pelvic drop and hip adduction angle, specific exercises might improve physical function and lower limb dynamic alignment during gait.

Individual joint contributions to the total support moment during the sit-to-stand task differentiate mild and moderate knee osteoarthritis.

BACKGROUND: Knee osteoarthritis tends to modify the kinematics and kinetics of the sit-to-stand task. However, it is not clear whether the different degrees of knee osteoarthritis differentiate regarding these aspects. The objective was to identify if the trunk flexion, lower limb kinetics, total support moment, and individual joint contributions to the total support moment during the sit-to-stand task are different between patients with mild and moderate knee osteoarthritis. METHODS: Sixty-two participants were grouped as follows: moderate knee osteoarthritis (n = 16), mild knee osteoarthritis (n = 25), and controls (n = 21). The participants performed a sit-to-stand task, which was analyzed using a 3D-motion system and a force plate. FINDINGS: The three phases of the sit-to-stand task were analyzed. During Phase1, the moderate osteoarthritis group decreased the total support moment (P = 0.012). During Phase2, the moderate osteoarthritis group showed higher trunk flexion (P = 0.023) and lower internal hip and knee extension moments (P ≤ 0.001 and P ≤ 0.040, respectively) when compared to controls. Also in Phase2, both the mild and moderate groups used lower total support moment (P = 0.019, and P ≤ 0.001, respectively). When compared to the controls and mild osteoarthritis group, those with moderate osteoarthritis presented higher hip joint contribution to the total support moment (P ≤ 0.001 and P = 0.006, respectively) as well as lower knee joint contribution (P ≤ 0.003 and P = 0,013, respectively). INTERPRETATION: Those with moderate osteoarthritis showed modified sit-to-stand movement pattern. While in Phase3 a higher contribution of the hip joint to the total support moment was observed, during previous phases the individuals were able to decrease the load on the knee without influencing the lower limb load distribution.

Kinematic alterations of the lower limbs and pelvis during an ascending stairs task are associated with the degree of knee osteoarthritis severity.

BACKGROUND: Individuals with knee osteoarthritis (OA) generally demonstrate great difficulty in ascending stairs. The strategies and compensations used by these individuals in stair activities have not been fully established. The purpose of this study was to investigate the joint kinematics of the pelvis, hip, knee and ankle throughout the gait cycle, in the sagittal and frontal planes, in individuals with mild and moderate knee OA, during an ascending stairs task. METHODS: Thirty-one individuals with knee OA and 19 controls were subjected to clinical and radiographic analysis, divided into three groups: control, mild knee OA, and moderate knee OA. Participants answered a self-reported questionnaire, carried out performance-based tests, and their kinematic data were recorded during an ascending stairs task using an eight-camera Qualisys 3D-Motion analysis system. RESULTS: The individuals with moderate degrees of knee OA demonstrated kinematic alterations in the pelvis, hip, knee, and ankle in the sagittal plane. The individuals with mild degrees of knee OA demonstrated kinematic alterations of the hip in the frontal plane, and kinematic alterations of the ankle in the sagittal plane. CONCLUSIONS: The ascending stairs task allowed verification of meaningful information regarding gait strategies used by individuals with mild and moderate knee OA. The strategies of these two groups of individuals are different for this task, although more pronounced in individuals with moderate knee OA. The findings should be taken into account in the development of rehabilitation programs.

The relationship between external knee moments and muscle co-activation in subjects with medial knee osteoarthritis.

PURPOSE: External knee moments are reliable to measure knee load but it does not take into account muscle activity. Considering that muscle co-activation increases compressive forces at the knee joint, identifying relationships between muscle co-activations and knee joint load would complement the investigation of the knee loading in subjects with knee osteoarthritis. The purpose of this study was to identify relationships between muscle co-activation and external knee moments during walking in subjects with medial knee osteoarthritis. METHODS: 19 controls (11 males, aged 56.6±5, and BMI 25.2±3.3) and 25 subjects with medial knee osteoarthritis (12 males, aged 57.3±5.3, and BMI 28.2±4) were included in this study. Knee adduction and flexion moments, and co-activation (ratios and sums of quadriceps, hamstring, and gastrocnemius) were assessed during walking and compared between groups. The relationship between knee moments and co-activation was investigated in both groups. FINDINGS: Subjects with knee osteoarthritis presented a moderate and strong correlation between co-activation (ratios and sums) and knee moments. INTERPRETATION: Muscle co-activation should be used to measure the contribution of quadriceps, hamstring, and gastrocnemius on knee loading. This information would cooperate to develop a more comprehensive approach of knee loading in this population.

Ankle strength impairments associated with knee osteoarthritis.

BACKGROUND: Knee Osteoarthritis seems to negatively impact ankle biomechanics. However, the effect of knee osteoarthritis on ankle muscle strength has not been clearly established. This study aimed to evaluate the ankle strength of the plantar flexors and dorsiflexors of patients with knee osteoarthritis in different degrees of severity. METHODS: Thirty-seven patients with knee osteoarthritis and 15 controls, subjected to clinical and radiographic analysis, were divided into three groups: control, mild, and moderate knee osteoarthritis. Participants answered a self-reported questionnaire and accomplished a muscle torque assessment of the ankle using the Biodex dynamometer in isometric, concentric and eccentric modes. FINDINGS: The mild osteoarthritis group (peak torque=26.85(SD 3.58)) was significantly weaker than the control (peak torque=41.75(SD 4.42)) in concentric plantar flexion (P<0.05). The control and mild osteoarthritis groups were not significantly different from the moderate osteoarthritis group (peak torque=36.12(SD 4.61)) in concentric plantar flexion. There were no significant differences for dorsiflexion among the groups; however the control and moderate osteoarthritis groups presented large and medium standardized mean differences. The mild osteoarthritis group was significantly lower than the control and moderate osteoarthritis groups in the concentric plantar flexion by concentric dorsiflexion torque ratio. INTERPRETATION: Ankle function exhibited impairments in patients with knee osteoarthritis, especially in the plantar flexion torque, in which the mild osteoarthritis group was weaker than the control. Interestingly, patients with moderate knee osteoarthritis showed results similar to the control group in plantar flexion torque. The results raise the possibility of a compensatory mechanism of the plantar flexors developed by patients in more advanced degrees to balance other muscle failures.

Telefonemas mensais e calendários como registro para a taxa de quedas de idosos da comunidade inseridos em um ensaio clínico randomizado / Llamadas telefónicas mensuales y calendarios como registro de tasa de caída de ancianos de una comunidad en un ensayo clínico aleatorizado / Monthly phone calls and calendars to record falls rate in community-dwelling older adults included in a randomized clinical trial

RESUMO Os objetivos deste estudo de caráter longitudinal prospectivo foram analisar telefonemas mensais e calendários como registro da taxa de quedas de idosos da comunidade ao longo de 22 semanas e verificar os fatores relacionados à adesão ao calendário de quedas. Os participantes passaram por avaliações de anamnese, nível de atividade física, medidas neuropsicológicas e mobilidade. Receberam também um calendário de quedas que deveria ser preenchido, ao longo das 22 semanas, no(s) dia(s) em que o evento ocorresse. Ademais, os idosos foram contatados mensalmente por telefone para o questionamento da ocorrência de quedas naquele período. Para análise dos dados, foi adotado nível de significância de α=0,05, e para execução dos testes estatísticos foi utilizado o software SPSS 20.0. Os dois instrumentos foram comparados quanto à "sensibilidade" e à "especificidade". Foram incluídos 52 idosos no estudo, com média de idade de 70,5 anos. A adesão ao método do calendário foi de 63,4% em comparação à estratégia dos telefonemas. Dos nove participantes que relataram quedas pelos telefonemas, três as notificaram no calendário, resultando em uma sensibilidade de 33%. Dos 43 idosos que não relataram quedas por telefonemas, 31 entregaram o calendário sem registro, o que resultou em uma especificidade do calendário de 72%. Anos de escolaridade, pontuação no Miniexame de Estado Mental e desempenho no exame cognitivo de Addenbrooke (versão revisada) influenciaram significativamente na adesão ao calendário de quedas. Concluiu-se que houve maior notificação de quedas pelo método do telefonema mensal em comparação ao do calendário em idosos da comunidade.

RESUMEN Los objetivos de este estudio longitudinal prospectivo fueron evaluar llamadas telefónicas mensuales y calendarios como registro de la tasa de caída de ancianos en la comunidad durante 22 semanas, así como identificar los factores relacionados con la adherencia al calendario de caídas. Los participantes se sometieron a evaluaciones de anamnesis, nivel de actividad física, medidas neuropsicológicas y movilidad. También recibieron un calendario de caídas que debían llenar, durante las 22 semanas, en el/los día/s de ocurrencia del evento. Además, los ancianos recibían llamadas telefónicas mensuales para informar la ocurrencia de caídas en ese periodo. Para el análisis de datos, se adoptó un nivel de significancia de α=0,05, y se utilizó el software SPSS 20.0 para realizar las pruebas estadísticas. Los dos instrumentos se compararon con relación a la "sensibilidad" y "especificidad". Participaron 52 ancianos en el estudio, con una edad media de 70,5 años. La adherencia al método del calendario fue del 63,4% en comparación con la estrategia de llamada telefónica. De los nueve participantes que informaron por llamadas telefónicas la ocurrencia de caídas, tres las relataron en el calendario, lo que da como resultado una sensibilidad del 33%. De los 43 ancianos que no informaron caídas, 31 entregaron el calendario sin registro, lo que resultó en una especificidad de calendario del 72%. El nivel educativo, las puntuaciones del Miniexamen del Estado Mental y el desempeño en el Examen Cognitivo de Addenbrooke (versión revisada) influyeron significativamente en la adherencia al calendario de caídas. Se concluyó que hubo mayor notificación de caídas con el método de llamada telefónica mensual en comparación con el método de calendario entre los ancianos de la comunidad.

ABSTRACT This longitudinal study aimed to analyze monthly phone calls and calendars as a mean to record falls rate in community-dwelling older adults over 22 weeks, and to verify factors related to adherence to the falls calendar. Participants underwent an assessment composed by anamnesis, level of physical activity, neuropsychological measures, and mobility. They also received a schedule of falls that should be completed over 22 weeks, on the day(s) a fall occurred. Moreover, the volunteers received monthly phone calls to inquire about occurrence of falls over time. For data analysis, a α=0.05 significance level was adopted and the SPSS software (20.0) was used to perform statistical tests. The two tools were compared regarding "sensitivity" and "specificity." In total, 52 older adults composed the final sample, with a mean age of 70.5 years old. The adherence to the calendar was 63.4% compared to phone calls. Of nine participants who reported falls by phone calls, three notified them in the calendar, resulting in a 33% sensitivity. Out of the 43 people who did not report falls by phone calls, 31 delivered the calendar without registration. Thus, the specificity of the calendar was 72%. Schooling level, Mini Mental State Exam score and the Addenbrooke's Cognitive Examination (revised version) score significantly influenced adherence to the calendar. In conclusion, there was a greater registration of falls by the monthly phone call compared to the calendar tool in community-dwelling older adults.

Operative strategies of HLB's scouts of a citrus property within the State of Sao Paulo, Brazil.

This research aimed to study the activity of the HLB's scouts, workers whose function is to identify symptomatic plants, in order to understand the physical constraints, cognitive and organizational involved in accomplishing the task, characterizing the operative approach used to identify diseased plants, and to elucidate what aspects hinder the identification of symptoms. The method adopted for the research was the Ergonomic Analysis of Work--EAW [6]. The results, after validation with the operators and management, allowed understanding the complex relationships between the physical, cognitive and organizational aspects present on activity. Major difficulties were observed mainly in relation to the disposal of the scouts on the platforms and in relation to working hours, at the beginning and end of the journey. Important findings have highlighted strategies, unknown by the organization, used by scouts to locate candidates' trees to the fine analysis of investigation of symptoms. In conclusion, the analysis enable to understand the constraints and find technical and organizational solutions to the survey work on citrus groves as well as it showed signs and symptoms not investigated yet or rarely considered by researchers involved on searches aimed at increasing the ability to diagnose the disease in the field.

Conclui-se que o treino específico da musculatura da mão durante o vôo, aespecificidade e o período de treinamento interferem na força muscular isométricada mão.

Pilots from Brazilian Air Force Academy (AFA) perform strentgth- andaccuracy-demanding hand movements, which may modify muscle strength. Theaim of this study was to analyse hand isometric strength of grip and pulp-to-pulp,tripode and lateral pinch in three groups of male AFA pilots: ADS (Air DemonstrationSquadron), n=15; IP (instructor pilots), n=16; and TP (training pilots), n=6. Pilotsbody positioning during tests followed the standards of the American Society ofHand Therapists; the sequence of assessed movements was predefined in order toprevent muscle fatigue. The maximum isometric muscle force was collected in acontraction kept for 6 seconds. As to grip, results show significant differences withinall groups, favouring dominant hands; also, mean ADS grip values were significantlyhigher than the other groups’. Tripode pinch ADS mean values were significantlyhigher than training pilots’; and dominant hands significantly overtopped nondominantones in ADS and IP groups. It may thus be said that specific hand muscletraining during flight, as well as training specialization and duration influence handisometric muscle strength.

Estudo comparativo da força muscular da mão entre cadetes homens e mulheres da Força Aérea Brasileira / Grip and pinch strength in Brazilian Air Force cadet pilots: a comparative study between men and women

O objetivo do estudo foi quantificar a força muscular da mão, nos movimentos de preensão palmar e três tipos de pinça, comparando os cadetes homens e mulheres. Foram avaliados 31 cadetes da Academia da Força Aérea Basileira, sendo 17 homens e 14 mulheres, com os dinamômetros Jamar e Preston Pinch Gauge. A média de preensão das mulheres foi de 31,4 kgf no lado dominante e 29,3 kgf no lado não-dominante; nos homens, foi 43,6 e 41,2 kgf, respectivamente (p<0,01). Na pinça lateral, a média feminina foi de 7,4 kgf e masculina, 10,2 kgf, no lado dominante (p<0,01); na pinça trípode, a média das mulheres foi de 7,2 kgf no lado dominante e 7,1 kgf do lado não-dominante; nos homens, foi respectivamente de 9,8 kgf e 9,5 kgf (p<0,01); na pinça polpa-a-polpa, as médias femininas foram de 4,9 e 4,6 kgf nos lados dominante e não-dominante; dos homens, foram de 6,5 e 5,7 kgf nos lados dominante e não-dominante, respectivamente (p<0,01). A força de preensão palmar, pinça lateral, pinça trípode e pinça polpa-a-polpa foi significantemente maior nos cadetes masculinos do que nas mulheres. Ambos os sexos mostraram mais força do lado dominante do que no não-dominante, exceto na pinça trípode. Quando diferença dos valores obtidos nos cadetes, tanto em relação ao sexo quanto à dominância. Esses achados podem ser relevantes na avaliação fisioterapêutica e para o desempenho desses pilotos...

The aim of this study was to quantify the hand muscle strength during gripand pinch movements, and to compare results between men and women. Thirtyone cadet pilots (17 men and 14 women) from the Brazilian Air Force Academy were assessed by means of Jamar dynamometer (grip) and Preston Pinch Gauge (pinch). Female cadets mean grip was 31.4 kgf at dominant hand and 29.3 kgf at non-dominant hand; in male subjects, corresponding values were 43.6 kgf and 41.2 kgf. Mean female lateral pinch at the dominant hand was 7.4 kgf and men’s, 10.2 kgf (p<0.01); tripod pinch values were 7.2 kgf at dominant side and 7.1 kgf at non-dominant for women, and 9.8 kgf and 9.50 kgf for men, respectively (p<0.01); women pinch values were 4.9 kgf and 4.6 at dominant and non-dominant hands, and men's, 6.5 kgf and 5.7 kgf respectively (p<0.01). Grip, pinch, lateral pinch and tripod pinch were all significantly higher (p<0.01) in men than in women. Both sexes showed higher strength at the dominant side, except of the tripod pinch. When compared to the population in general, there are little differences among cadets, both as to sex and dominance. These findings may be of relevance both for pilots performance and physical therapy assessment...
