Acute outcomes of acupuncture and dry needling over peripheral acute fatigue in untrained healthy volunteers: A randomized controlled clinical trial.

Peripheral acute fatigue (PAF) is defined as when the skeletal muscle is incapable of generating power. We aimed to investigate the acute effects of traditional Chinese acupuncture (TCA) and dry needling (DN) over PAF induced on the biceps brachii of untrained healthy volunteers. We conducted a randomized, single-blind controlled clinical trial. All volunteers (n = 45) underwent fatigue induction protocols repeated before and after treatment with TCA (TCA group; TCAg; n = 15), DN (DN group; DNg; n = 15), and rest (control group; Cg; n = 15). Assessments of PAF, skin temperature, and exercise time occur before and after each event: 1st fatigue induction (FI), treatment, and 2nd FI. We used repeated measures ANOVA adjusted with Bonferroni post hoc test to determine any change in tested variables (PAF-VAS, PAF-EMG, and skin temperature) at different time points compared to the baseline. Paired Samples t-test was used for the variable exercise times. All statistical tests considered' the significance level at p ≤ 0,05. There was no difference between groups in acute fatigue recovery (p = 0.19). All intragroup analyses were significant (p ≤ 0.05) and all volunteers show a reduction in fatigue perception after treatment (p ≤ 0,05), however, exercise time did not ameliorate after TCA or DN (p > 0.77). A single session of TCA and, DN can equally reduce fatigue, temperature, and exercise time over PAF induced on biceps brachii of untrained healthy volunteers.

Do Higher Transcranial Direct Current Stimulation Doses Lead to Greater Gains in Upper Limb Motor Function in Post-Stroke Patients?

Objective: To investigate whether a higher number of transcranial direct current stimulation (tDCS) sessions results in a greater improvement in upper limb function in chronic post-stroke patients. Materials and methods: A randomized, sham-controlled, double-blind clinical trial was conducted in 57 chronic post-stroke patients (≥ 3 months after their injuries). The patients were allocated to receive sessions of tDCS combined with physiotherapy and divided into three groups (anodal, cathodal, and sham). The Fugl-Meyer Assessment of Upper Extremity (FMA-UE) was used to assess the sensorimotor impairment of the patients' upper limbs before (baseline) and after five and ten sessions. The percentage of patients who achieved a clinically significant improvement (> five points on the FMA-UE) was also analyzed. Results: The FMA-UE score increased after five and ten sessions in both the anodal and cathodal tDCS groups, respectively, compared to the baseline. However, in the sham group, the FMA-UE score increased only after ten sessions. When compared to the sham group, the mean difference from the baseline after five sessions was higher in the anodal tDCS group. The percentage of individuals who achieved greater clinical improvement was higher in the stimulation groups than in the sham group and after ten sessions when compared to five sessions. Conclusions: Our results suggest that five tDCS sessions are sufficient to augment the effect of standard physiotherapy on upper limb function recovery in chronic post-stroke patients, and ten sessions resulted in greater gains.

Effectiveness of Whole-Body Vibration Combined with Multicomponent Training on the Risk of Falls and Quality of Life in Elderly Women with Osteoporosis: Study Protocol for a Randomized Controlled Clinical Trial.

Osteoporosis and the risk of falls increase the risk of fractures and events of falls. Prescriptions and programs for different forms of exercise have different impacts on the risk of falls, and exercises from multiple categories of whole-body vibration can be effective. This study aims to evaluate the effectiveness of whole-body vibration (WBV) protocol combined with multicomponent training (MCT) in elderly women with osteoporosis and their history of falls. Our proposal is a protocol for a randomized clinical trial, divided into two stages: First, development of a protocol for WVB combined with MCT for elderly women with osteoporosis and a history of falls, under the Guidelines of the American College of Sports Medicine, and following the recommendations of the Standard Protocol Items Recommendations for Interventional Trials (SPIRIT), and second, a randomized controlled clinical trial following the Consolidated Standards of Reporting Trials (CONSORT). This trial will have implications for the effectiveness of a vibration protocol combined with multicomponent exercise on the risk of falls and quality of life for older women with osteoporosis. We expect that adding full-body vibration to an exercise protocol will decrease the risk of falls and improve participants' quality of life, as well as their strength, balance, and functional capacity.

Acupuncture and Dry Needling in the Reduction of Peripheral Acute Fatigue Induced in the Biceps Braquii: Protocol for a Single-blinded Randomized Controlled Clinical Trial.

The present study aims to propose a protocol to verify the efficacy and acute effects of traditional Chinese acupuncture, dry needling, and the rest in peripheral acute fatigue (PAF) induced by intermittent isometric contractions of the nondominant biceps brachii (BB) of nonphysically active men in a randomized, single-blind clinical trial assessed with surface electromyography, contraction time in seconds, infrared thermal imaging, and visual analog scale applied to the PAF. These instruments will evaluate the median frequency, endurance time, temperature (°C), and perceived fatigue in BB of the volunteers. The measurements will be collected in four moments (Test 0, 01, 02, and 03) divided between the beginning and the end of two sets of exercises (Exercises 01 and 02) of intermittent isometric contractions. TRIAL IDENTIFIER: NCT03448120 in www.clinicaltrials.gov.

Global Postural Re-education in non-specific neck and low back pain treatment: A pilot study.

BACKGROUND: Spinal pain is an important public health issue that brings biopsychosocial problems. Global Postural Re-education (GPR) is one of its treatments. OBJECTIVE: Evaluate the effects of GPR on pain, flexibility, and posture of individuals with non-specific low back pain and/or neck pain for more than six weeks. METHODS: The study enrolled 18 individuals, which were randomized into two groups: GPR group (GPRG; n= 09), submitted to 10 sessions of GPR and control group (CG; n= 09), not submitted to any technique. The evaluations were done before and after the GPRG sessions, for pain perception (Visual Analogue Scale - VAS), flexibility (finger-floor test) and posture (SAPO). The re-evaluation was done in the GPRG after the end of 10 treatment sessions and, in the GC, after the time equivalent to 10 sessions. The level of significance was set at p< 0.05. RESULTS: This pilot study has no homogeneity between groups. GPRG presented improvement in pain and flexibility, but showed no changes in posture. In the CG, there was no difference in the variables evaluated in this study. CONCLUSION: GPR had positive effects on pain and flexibility, but did not present a significant effect on posture.
