Fibromyalgia syndrome (FMS) has multifactorial etiology characterized by various clinical manifestations and low ability to perform physical activities which contributes to low aerobic functional capacity, and consequently worsens pain sensitivity and quality of life. In addition, studies have shown that autonomic dysfunction plays an important role in FMS. Thus, the present thesis consisted of three studies in order to elucidate unknown aspects regarding the aforementioned dysfunctions. The Study I, entitled Reliability of heart period and systolic arterial pressure variabilities in women with fibromyalgia syndrome", aimed to define absolute and relative reliability of spectral indices of cardiovascular autonomic control in the supine position in women with FMS. The results presented good relative reliability, indicating that the indices can be useful as parameters to quantify if a variation was consistent and accurate in the retest besides adding crucial information for clinical research and clinical evaluation of FMS patients. The Study II, entitled "Cardiovascular autonomic control and baroreflex sensitivity after aquatic physical training in women with fibromyalgia: a randomized controlled clinical trial", aimed to evaluate the effect of aquatic physical training (APT) on cardiovascular autonomic control and baroreflex sensitivity (BRS) in women with FMS. After the APT, in supine position, training group (TG) showed a cardiovascular autonomic profile characterized by higher values of HFRR (nu) (p=0.01) and lower values of LFRR/HFRR (p=0.03) and LFSAP (p=0.04) compared to control group (CG). In addition, the indexes of BRS resulted increased in TG compared to CG both in supine (p=0.05) and during standing (p=0.03). The Study III, entitled " Oxygen uptake and body composition after aquatic physical training in women with fibromyalgia: a randomized controlled trial", aimed to investigate whether APT can help improve body composition and increase the aerobic functional capacity in women with FMS, and whether oxygen uptake (VO2) related to lower body mass (LBM) can better quantify the functional capacity of this population. APT with standardized intensities did not cause significant changes in body composition, but was effective in promoting increased VO2 at peak CPET in women with FMS. However, VO2 related to LBM more accurately reflected changes in aerobic functional capacity at ventilatory anaerobic threshold (VAT) level after to APT. The Study IV, entitled “Effects of aquatic training and detraining on women with fibromyalgia: controlled randomized clinical trial” aimed to evaluate variables VO2 relative to LBM and clinical symptomatology in women with FMS submitted to APT and after 16 weeks of detraining period, and to evaluate the association between the magnitude of VO2 improvement relative to LBM and clinical symptomatology. After APT, TG presented an increase in VO2 relative to LBM (p <0.05), in addition to an increase in pressure pain threshold (PPT) and visual analogue scale (VAS) well-being and lower VAS pain and Fibromyalgia Impact Questionnaire score (FIQ) (p <0.05). However, these improvements were not maintained after the 16-week detraining period (p> 0.05). In addition, no significant correlations were observed between improvement of clinical manifestations and increased VO2 relative to LBM after APT (p> 0.05).

Introduction: Stroke has been described as the third leading cause of death and the leading cause of disability in the adult population worldwide. Deficits in lower limb functions often persist in the vast majority of cases, affecting gait and functional mobility. In this context, several interventions are applied in the clinical practice to optimize functional performance. Cryotherapy is among the techniques used in order to temporarily reduce spasticity, allowing the performance of functional training, such as walking. However, its effects on muscle tone, muscle performance and gait pattern of individuals with chronic hemiparesis have not yet been elucidated. Objectives: To investigate the immediate effects of cryotherapy (ice pack) on muscle tone, isometric and isokinetic torque of the dorsiflexor and plantar flexor muscles, and angular and spatiotemporal gait parameters in chronic spastic hemiparetic individuals. Methods: Experimental design: randomized crossover controlled study. Participants: Sixteen chronic hemiparetic subjects. Intervention: Cryotherapy (ice pack) or Control Intervention (sand pack at room temperature) applied on the plantar flexor muscles of the paretic limb. Assessments (pre / post intervention): 1) Muscle tone, according to the Modified Ashworth Scale (MAS); 2) Spatiotemporal parameters and angular kinematics of the hip, knee and ankle (flexion / extension) during gait obtained through a three-dimensional motion analysis system (Qualisys); 3) Isometric, concentric and eccentric torque of dorsiflexion and flexorplantar, evaluated in isokinetic dynamometer. Statistical analysis: Two-way repeated measures ANOVA test was used to analyze all kinematic and torque variables. Non-parametric Wilcoxon and Mann-Whitney tests were used for comparisons of the score in the MAS, since it is considered a categorical variable. Significance level of 0.05 was considered for all statistical analysis. Results: Cryotherapy reduced the tone of the plantar flexors, but did not alter the capacity of torque generation or spatiotemporal and angular parameters (sagittal plane) during gait compared to the control intervention. Conclusion: The findings of this study suggest that cryotherapy (ice pack) applied on the plantar flexor muscles of individuals with chronic hemiparesis appears to be an effective technique to reduce muscle tone clinically measured but does not affect muscle performance and gait pattern of these individuals.
