Summary:Allogeneic bone marrow transplantation (BMT) has been successfully used for the treatment of several hematological malignancies; however, it is associated with transplant-related toxicities such as functional impairment and muscle weakness. In order to analyze how an exercise program may influence muscle strength in patients undergoing BMT, we carried out a prospective study assessing patients from the pre-BMT phase to 16 weeks post-BMT. In all, 18 patients underwent three trials: (1) pre-BMT, (2) after marrow engraftment, and (3) 6 weeks after trial 2. After trial 2, the patients were randomized in a control group (CG) or treatment group (TG), which received a 6-week exercise program with active exercise, muscle stretching and treadmill walking. The results obtained in trial 1 showed similar values for CG and TG, as both groups had muscle strength lower than normal patterns based on data concerning age, sex and weight. In trial 2, CG and TG showed similarly decreased values. In trial 3, TG showed values higher than CG for all muscle groups tested. These results suggest that the exercise program was efficient in promoting an increase of muscle strength after allogeneic BMT.

IntroductionEarly mobilization can be performed in critically ill patients and improves outcomes. A daily cycling exercise started from day 5 after ICU admission is feasible and can enhance functional capacity after hospital discharge. In the present study we verified the physiological changes and safety of an earlier cycling intervention (< 72 hrs of mechanical ventilation) in critical ill patients.MethodsNineteen hemodynamically stable and deeply sedated patients within the first 72 hrs of mechanical ventilation were enrolled in a single 20 minute passive leg cycling exercise using an electric cycle ergometer. A minute-by-minute evaluation of hemodynamic, respiratory and metabolic variables was undertaken before, during and after the exercise. Analyzed variables included the following: cardiac output, systemic vascular resistance, central venous blood oxygen saturation, respiratory rate and tidal volume, oxygen consumption, carbon dioxide production and blood lactate levels.ResultsWe enrolled 19 patients (42% male, age 55±17 years, SOFA = 6 ± 3, SAPS3 score = 58 ± 13, PaO2/FIO2 = 223±75). The median time of mechanical ventilation was 1 day (02), and 68% (n=13) of our patients required norepinephrine (maximum concentration = 0.47 µg.kg -1.min-1). There were no clinically relevant changes in any of the analyzed variables during the exercise, and two minor adverse events unrelated to hemodynamic instability were observed.ConclusionsIn our study, this very early passive cycling exercise in sedated, critically ill, mechanically ventilated patients was considered safe and was not associated with significant alterations in hemodynamic, respiratory or metabolic variables even in those requiring vasoactive agents.

Objective:  This study assessed the effects of an aquatic respiratory exercise‐based program in patients with fibromyalgia (FMS). Methods:  Forty women, aged between 20 and 60 years, were randomly assigned into two groups of 20 patients: the aquatic respiratory exercise‐based program (ARG) and the control group (CTL). The ARG group performed the exercise program for 1 h, four times a week, for 4 weeks which included: (i) warming‐up; (ii) respiratory exercises, consisting of five different breathing patterns, along with upper, lower limbs and trunk movements (45 min); and (iii) relaxation exercises. Both groups were included in supervised recreational activities of 1 h, once a week, for 4 weeks. Questionnaires were applied before and after intervention to assess quality of life and functional capacity (SF‐36, Fibromyalgia Impact Questionnaire [FIQ]), anxiety (Hamilton Anxiety Scale [HAS]), and quality of sleep (Pittsburg Sleep Quality Index [PSQI]). Number of tender points and pain (Visual Analogue Scale [VAS]) were also evaluated. Results:  At baseline there was no difference between the two groups, including number of tender points and questionnaire responses. After intervention, the ARG group, compared with the CTL group, showed improvement in SF‐36 scores (physical functioning P = 0.001, bodily pain P = 0.001, vitality P = 0.009, social functioning P = 0.001, emotional role P = 0.001), in FIQ (total score P = 0.049, work missed P = 0.036, fatigue P = 0.013, morning tiredness P = 0.007) plus in VAS‐pain (P = 0.029), VAS‐dyspnea (P = 0.04), anxiety (HAS P = 0.005) and quality of sleep (PSQI P = 0.004). Conclusions:  The short‐term aquatic respiratory exercise‐based program improved pain, quality of life, functional capacity, anxiety and quality of sleep in patients with FMS and may be a relevant addition to the treatment of these patients.

Transcranial Direct Current Stimulation (tDCS) is a non-invasive technique used to modulate neural tissue. Neuromodulation apparently improves cognitive functions in several neurologic diseases treatment and sports performance. In this study, we present a comprehensive, integrative review of tDCS for motor rehabilitation and motor learning in healthy individuals, athletes and multiple neurologic and neuropsychiatric conditions. We also report on neuromodulation mechanisms, main applications, current knowledge including areas such as language, embodied cognition, functional and social aspects, and future directions. We present the use and perspectives of new developments in tDCS technology, namely high-definition tDCS (HD-tDCS) which promises to overcome one of the main tDCS limitation (i.e., low focality) and its application for neurological disease, pain relief, and motor learning/rehabilitation. Finally, we provided information regarding the Transcutaneous Spinal Direct Current Stimulation (tsDCS) in clinical applications, Cerebellar tDCS (ctDCS) and its influence on motor learning, and TMS combined with electroencephalography (EEG) as a tool to evaluate tDCS effects on brain function.

Brazilian version of the foot health status questionnaire (FHSQ-BR): cross-cultural adaptation and evaluation of measurement properties. Clinics. 2008;63(5):595-600. OBJECTIVE:To conduct a cross-cultural adaptation of the Foot Health Status Questionnaire into Brazilian-Portuguese and to assess its measurement properties. INTRODUCTION:This instrument is an outcome measure with �0 domains with scores ranging from 0-�00, worst to �est, rehis instrument is an outcome measure with �0 domains with scores ranging from 0-�00, worst to �est, respectively. The translated instrument will improve the examinations and foot care of rheumatoid arthritis patients. METHODS: The questions were translated, �ack-translated, evaluated �y a multidisciplinary committee and pre-tested (n = 40 rheumatoid arthritis su�jects). The new version was su�mitted to a field test (n = 65) to evaluate measurement properties such as test-retest relia�ility, internal consistency and construct validity. The Health Assessment Questionnaire, Numeric Rating Scale for foot pain and Sharp/van der Heijde scores for foot X-rays were used to test the construct validity. RESULTS: The cross-cultural adaptation was completed with minor wording adaptations from the original instrument. The evaluation of measurement properties showed high relia�ility with low variation coefficients �etween interviews. The α-Cron�ach coefficients varied from 0.468 to 0.855, while correlation to the Health Assessment Questionnaire and Numeric Rating Scale was statistically significant for five out of eight domains. DISCUSSION: Intra-and inter-o�server correlations showed high relia�ility. Internal consistency coefficients were high for all domains, revealing higher values for less su�jective domains. As for construct validity, each domain revealed correlations with a specific group of parameters according to what the domains intended to measure. CONCLUSION: The FHSQ was cross-culturally adapted, generating a relia�le, consistent, and valid instrument that is useful for evaluating foot health in patients with rheumatoid arthritis.

Background: Novel coronavirus disease (COVID-19) morbidity is not restricted to the respiratory system, but also affects the nervous system. Non-invasive neuromodulation may be useful in the treatment of the disorders associated with COVID-19.Objective: To describe the rationale and empirical basis of the use of non-invasive neuromodulation in the management of patients with COVID-10 and related disorders.Methods: We summarize COVID-19 pathophysiology with emphasis of direct neuroinvasiveness, neuroimmune response and inflammation, autonomic balance and neurological, musculoskeletal and neuropsychiatric sequela. This supports the development of a framework for advancing applications of non-invasive neuromodulation in the management COVID-19 and related disorders.Results: Non-invasive neuromodulation may manage disorders associated with COVID-19 through four pathways: (1) Direct infection mitigation through the stimulation of regions involved in the regulation of systemic anti-inflammatory responses and/or autonomic responses and prevention of neuroinflammation and recovery of respiration; (2) Amelioration of COVID-19 symptoms of musculoskeletal pain and systemic fatigue; (3) Augmenting cognitive and physical rehabilitation following critical illness; and (4) Treating outbreak-related mental distress including neurological and psychiatric disorders exacerbated by surrounding psychosocial stressors related to COVID-19. The selection of the appropriate techniques will depend on the identified target treatment pathway.Conclusion: COVID-19 infection results in a myriad of acute and chronic symptoms, both directly associated with respiratory distress (e.g., rehabilitation) or of yet-to-be-determined etiology (e.g., fatigue). Non-invasive neuromodulation is a toolbox of techniques that based on targeted pathways and empirical evidence (largely in non-COVID-19 patients) can be investigated in the management of patients with COVID-19.

[Purpose] The aim of this study was to verify the decline in functionality of elderly people. [Subjects and Methods] The study subjects comprised 152 individuals (96 women; 56 men) divided into 3 groups: G1 (60 to 69 years, n=53); G2 (70 to 79 years, n=65); and G3 (80 years or older, n=34). Physical performance, balance, mobility, and muscle strength were assessed using Short Physical Performance Battery (SPPB), Berg Balance Scale (BERG), Timed Up and Go (TUG) test, and leg press test, respectively. Comparison among age-stratified groups (G1, G2 and G3) and between genders were examined using analysis of variance with Tukey’s test as a post hoc test or the Kruskal-Wallis test with Bonferroni correction. [Results] SPPB and BERG scores decreased significantly in comparison between G1 and G3, and between G2 and G3 in women. TUG and leg press scores decreased significantly in comparison between G1 and G3 and between G2 and G3. [Conclusion] People in their 60s and 70s have similar functional characteristics (physical performance, balance, mobility and muscle strength for both genders), and functionality starts to decline when people are in their 80s.
