ABSTRACT
INTRODUCTION: Enhancing lung function can significantly improve daily life functionality for children with cerebral palsy, leading to increased interest in respiratory physiotherapy training devices in clinical practice. This study aims to evaluate the efficacy of devices (inspiratory muscle training and feedback devices) for improving pulmonary function through various respiratory parameters. METHODS: A systematic review with meta-analysis of randomized clinical trials was conducted in seven databases up until May 2023. The included studies focused on training inspiratory muscle function using specific devices (inspiratory muscle training and feedback devices) in children with cerebral palsy. The main outcomes were maximum expiratory pressure and maximum inspiratory pressure. Secondary outcomes included forced vital capacity, forced expiratory volume in 1 s, peak expiratory flow, and the Tiffenau index. The effects of respiratory treatment were calculated through the estimation of the effect size and its 95% confidence intervals. The risk of bias in the included studies was assessed using the Cochrane Collaboration's tool for assessing the risk of bias (RoB2). RESULTS: Nine studies were included in the systematic review with meta-analysis, involving a total of 321 children aged between 6 and 18 years after secondary analyses were conducted. Feedback devices were found to be more effective in improving maximum expiratory pressure (effect size -0.604; confidence interval -1.368 to 0.161), peak expiratory flow, forced expiratory volume in 1 s, and forced vital capacity. Inspiratory muscle training devices yielded better effectiveness in improving maximum inspiratory pressure (effect size -0.500; confidence interval -1.259 to 0.259), the Tiffeneau index, and quality of life. CONCLUSION: Both devices showed potential in improving pulmonary function in children with cerebral palsy. Further high-quality clinical trials are needed to determine the optimal dosage and the most beneficial device type for each pulmonary function parameter.
ABSTRACT
Objective: The aim of this investigation was to compare the thickness of the deep local muscles in the neck region, as well as local and widespread sensitivity and functionality, between individuals with migraine, Tension-Type Headache (TTH), and healthy controls. To date, we know that the onset of migraine and TTH share similar pathophysiological pathways. Nevertheless, there may be some anatomical and functional differences which would explain why clinicians may obtain variable results when treating both pathological entities with similar or equal approaches. Methods: An observational study was conducted in accordance with STROBE guidelines. The flexor longus colli and multifidus, two neck-stabilizing muscles, were measured using B-mode ultrasound imaging. The upper trapezius, masseter, temporalis, tibialis anterior, and median nerve all underwent bilateral pressure-pain threshold (PPT) assessments. Results: Ninety participants were enrolled in the study. All subjects were equally divided into TTH, migraine and control groups. The PPT values exhibited lower thresholds in patients with TTH than both migraine and healthy participants. Specifically, in the temporal muscle on both sides, patients with TTH exhibited a significantly lower threshold (p < 0.001)than both migraine and healthy participants. Patients with TTH displayed significantly lower thresholds in both upper trapezius muscles (right: p < 0.001; left: p = 0.001). Similar results were obtained for the tibialis anterior PPTs from both sides (p = 0.001 in both). However, both clinical groups exhibited lower thresholds than the healthy subjects (p < 0.001). In multifidus muscle cross-sectional area (CSA), no statistically significant differences were found between migraine patients and healthy subjects, both in relaxation and contraction (right; p > 0.05 and p > 0.05; left: p > 0.05 and p > 0.05). However, patients with TTH exhibited a smaller CSA than both migraine patients and healthy controls in multifidus relaxed and contracted state (right: p < 0.001 in both relaxed and contracted multifidus; left: p = 0.001 and p < 0.001, respectively). Similar results were obtained for the left longus colli muscle in both relaxation and contraction for patients with TTH and migraine compared with healthy subjects (p = 0.001 and p < 0.001, respectively, for muscle relaxation and p < 0.001 for muscle contraction). However, no significant differences were observed between patients with TTH and migraine (p < 0.05 in both relaxation and contraction). In the right longus colli, TTH and migraine patients had a significantly smaller CSA during contraction than healthy subjects (p < 0.001 in both comparisons). In the craniocervical flexion test, both groups of patients with TTH and migraine showed significantly lower values than healthy subjects (p < 0.001 in both comparisons). However, no significant differences were found between patients with TTH and migraineurs (p > 0.05). Conclusion: The findings provide a significant message for clinicians since anatomical and functional impairments were shown in patients with TTH and migraine. This study corroborates a lack of strength and smaller CSA in both clinical groups compared to controls. Therefore, strengthening programs may be addressed successfully for people with these pathological entities. To be more accurate, according to PPTs and CSA lower values in patients with TTH compared to migraine and controls, manual therapy approaches to desensitize craniocervical soft tissues and exercise therapy to increase endurance of deep cervical muscles may become meaningful especially in subjects with TTH. Nevertheless, in order to distinguish precisely between patients with TTH and migraine, different diagnostic strategies may be used in the future to describe these populations in further detail, which will assist health professionals in a more accurate treatment selection.
ABSTRACT
The aim of this study was to assess the effectiveness of microcurrent therapy for healing pressure ulcers in aged people. A multicentric, randomized clinical trial was designed with a sham stimulation control. The experimental group received an intervention following a standardized protocol for curing ulcers combined with 10 h of microcurrent therapy daily for 25 days. The sham group received the same curing protocol plus a sham microcurrent stimulation. The studied healing-related variables were the Pressure Ulcer Scale for Healing (PUSH) and the surface, depth, grade, and number of ulcers that healed completely. Three evaluations were conducted: pre-intervention (T1), 14 days following the start of the intervention (T2), and 1 day after the intervention was completed (T3). In total, 30 participants met the inclusion criteria (n = 15 in each group). The improvement in the PUSH at T2 and T3 was 16.8% (CI95% 0.5-33.1) and 25.3% (CI95% 7.6-43.0) greater in the experimental group versus the sham control, respectively. The reduction in the wound area at T2 and T3 was 20.1% (CI95% 5.2-35.0) and 28.6% (CI95% 11.9-45.3) greater in the experimental group versus the control, respectively. Microcurrent therapy improves the healing of pressure ulcers in older adults, both quantitatively and qualitatively.
