Primary dysmenorrhea (PD), a prevalent menstrual condition characterized by pelvic pain during the menstrual cycle, significantly impacts the quality of life of women and produces increased pain sensitivity that can persist throughout the menstrual cycle. However, scientific literature has not studied whether there are implications for alterations in muscle function and endurance in the abdominopelvic region during the non-painful phases of the menstrual cycle. The aim of this study was to compare muscle function and endurance capacity in the abdominopelvic region in women with PD versus women without this condition. An observational, cross-sectional study was designed to analyze muscle activation and endurance capacity using electromyography (EMG) during McGill exercises. Forty-four women were included, 22 with PD and 22 without dysmenorrhea. The results did not indicate significant differences in muscle activation and endurance of the abdominopelvic musculature between the two groups (p > 0.05). However, the analysis suggests that women with primary dysmenorrhea might develop compensatory strategies that allow them to maintain physical function despite their condition. These results suggest that the approach to PD could focus more on pain management rather than physical functionality, and more studies are needed from a comprehensive approach to more accurately evaluate the relationship between PD and muscle function., Competing Interests: Declarations.

Introduction: The objective of this review is to know the existing scientific evidence about the effects of mechanical ventilation (MV) on neurological development in low-birth-weight premature pediatric patients after 12 months of life, taking as background the direct impact that ventilation has on the central nervous system in the newborn during the first days of life., Methods: A systematic search was carried out between 2003 and 2024 in the data bases of: PUBMED, Cochrane Library Plus, PEDro, CINAHL, and SciELO, and two investigators scored the articles according to the Newcastle-Ottawa Assessment scale., Results: Were found 129 non-replicated articles, and 10 cohort and cross-sectional studies were selected that performed an assessment of neurodevelopment in the three spheres after 12 months of life in corrected age of premature infants exposed to ventilator support and related the two variables independently., Conclusions: Mechanical ventilation is an independent neurodevelopmental risk factor in low-birth-weight preterm infants. The time of exposure and the type of ventilation were the variables with the most scientific evidence., Systematic Review Registration: https://www.crd.york.ac.uk/, Identifier CRD42023446797., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Vargas Caicedo, de La Plaza San Frutos, Sosa Reina, Garcia Arrabe, Salniccia, Reina Aguilar and Estrada Barranco.)

Background : This cross-sectional observational study aimed to investigate differences in abdominal musculature thickness, pelvic tilt, and trunk mobility between women with primary dysmenorrhea (PD) and a control group (CG). Methods : Participants included 44 women (22 with PD and 22 controls) aged over 18, nulliparous, and of reproductive age. Ultrasound imaging was used to measure the thickness of the transverse abdominis (TrA), internal oblique (IO), external oblique (EO), and rectus abdominis (RA) muscles at rest and during contraction. Additionally, anterior pelvic tilt was assessed using the Palpation Meter (PALM), and trunk flexion and extension were measured using an accelerometer (activForce2). Results : Significant differences ( p < 0.05) were found in RA and EO muscle thickness, with lower values in the PD group compared to CG. However, there were no significant differences ( p > 0.05) in TrA and IO muscle thickness, anterior pelvic tilt, or trunk mobility between groups. Conclusions : These findings contribute to understanding the musculoskeletal factors potentially involved in dysmenorrhea. Further research is needed to explore associations between PD and structural and alignment parameters.

Introduction: Fatigue, postural control impairments, and reduced respiratory capacities are common symptoms in persons diagnosed with Multiple Sclerosis (MS). However, there is a paucity of evidence establishing correlations among these factors. The aim of this study is to analyze respiratory function in persons with MS compared to the control group as well as to analyze the relationship between fatigue, respiratory function and postural control in persons with MS., Materials and Methods: A total of 17 persons with MS and 17 healthy individuals were enrolled for this cross-sectional study. The evaluated parameters included fatigue assessed using the Visual Analog Scale-fatigue (VAS-F) and the Borg Dyspnea Scale, postural control assessed through the Mini Balance Evaluation System Test (Mini-BESTest), Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and Trunk Impairment Scale (TIS); and respiratory capacities measured by Maximum Inspiratory Pressure (MIP), Maximum Expiratory Pressure (MEP), Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), FEV1/FVC ratio, Diaphragmatic excursion and diaphragmatic thickness., Results: A very high correlation was observed between the Borg Dyspnoea Scale and the BBS ( r  = -0.768), TUG (0.867), and Mini-BESTest ( r  = -0.775). The VAS-F exhibited an almost perfect correlation solely with the TUG (0.927). However, none of the variables related to fatigue exhibited any correlation with the respiratory variables under study. Balance-related variables such as BBS and Mini-BESTest demonstrated a very high and high correlation. Respectively, with respiratory function variables MEP ( r  = 0.783; r  = 0.686), FVC ( r  = 0.709; r  = 0.596), FEV1 ( r  = 0.615; r  = 0.518). BBS exhibited a high correlation with diaphragmatic excursion ( r  = 0.591). Statistically significant differences were noted between the persons with MS group and the control group in all respiratory and ultrasound parameters except for diaphragmatic thickness., Conclusion: The findings suggest that decreased postural control and balance are associated with both respiratory capacity impairments and the presence of fatigue in persons with MS. However, it is important to note that the alterations in respiratory capacities and fatigue are not mutually related, as indicated by the data obtained in this study. Discrepancies were identified in abdominal wall thickness, diaphragmatic excursion, and respiratory capacities between persons with MS and their healthy counterparts., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Sanchez-Ruiz, de la Plaza San Frutos, Sosa-Reina, Sanz-Esteban, García-Arrabé and Estrada-Barranco.)

The Natural Semantic Networks (NSN) model is highly useful in analyzing the words that define a concept in terms of the value, strength, weight, or density that a specific population assigns to the construction of a learned concept. The main objective of this study was to describe the conceptualization of the concept of neurorehabilitation by Spanish physiotherapists specializing in this field using NSN. A phenomenological study is presented. The participants were physiotherapy professionals who graduated from three Spanish universities and were working in the field of neurorehabilitation. A questionnaire was administered via Google Forms, which was constructed using the NSN technique. A total of 191 physiotherapists participated in this study. The Spanish physiotherapists interviewed used a total of 1247 defining words for the concept of neurorehabilitation. The semantic core of the concept was mainly formed by the words 'treatment', 'recovery', 'functionality', 'neuroplasticity', and 'learning', which carried significant weight. Results were also presented taking into account the academic level and years of professional experience of the sample. The semantic network observed in this study allows us to elucidate the polysemy of the concept of neurorehabilitation, which is composed not only of certain associated words but also the meanings they imply.

The study aimed to investigate the effects of footwear on the electromyographic (EMG) activity of pelvic floor muscles (PFMs) and internal oblique (IO) muscles during running at different speeds. The study also aimed to explore the correlation between EMG activity of PFMs and IO muscles and participants' morphological characteristics. Ten nulliparous female runners were included in the study. The participants ran for 90 s at speeds of 9, 11, and 13 km/h wearing both traditional and minimalist shoes. EMG outcomes were presented as a percentage of maximum voluntary contraction (%MVC). Comparative analysis was conducted using the Wilcoxon rank test. Correlational analysis was performed using the Rho-Spearman correlation coefficient. The %MVC for the IO muscles was significantly lower when using minimalist shoes compared to traditional shoes ( p = 0.04). No statistically significant differences were found for the PFMs ( p > 0.05). The study also observed large correlations between age and %MVC of the PFMs and IO muscles (rho = -0.64; p = 0.04). Minimalist shoes decreased the activity of IO muscles in female runners. However, no significant differences in EMG activity of PFMs were found when comparing traditional and minimalist footwear. The long-term effects of minimalist footwear on EMG activity of PFMs and IO muscles, as well as their relationship to morphological characteristics, require further investigation.

The Trunk Control Measurement Scale (TCMS) is a valid and reliable tool to assess static and dynamic trunk control in cerebral palsy. However, there is no evidence informing about differences between novice and expert raters. A cross-sectional study was conducted with participants between the ages of 6 and 18 years with a CP diagnosis. The TCMS Spanish version (TCMS-S) was administered in-person by an expert rater, and video recordings were taken for later scoring by the expert and three other raters with varying levels of clinical experience. The intraclass correlation coefficient (ICC) was used to evaluate reliability between raters for the total and subscales of the TCMS-S scores. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) were also calculated. There was a high level of agreement between expert raters (ICC ≥ 0.93), while novice raters demonstrated good agreement (ICC > 0.72). Additionally, it was observed that novice raters had a slightly higher SEM and MDC than expert raters. The Selective Movement Control subscale exhibited slightly higher SEM and MDC values compared to the TCMS-S total and other subscales, irrespective of the rater's level of expertise. Overall, the study showed that the TCMS-S is a reliable tool for evaluating trunk control in the Spanish pediatric population with cerebral palsy, regardless of the rater's experience level.

Cognitive impairment is frequent in elderly subjects. It is associated with motor impairment, a limitation in quality of life and frequently, institutionalization. The aim of this work is to test the efficacy of a therapeutic group program based on action-observation learning., Methods: a non-randomized controlled trial study was conducted. We included 40 patients with cognitive impairment from a nursing home who were categorized into mild and moderate cognitive impairment and divided separately into a control and experimental group. Experimental group performed a 4-week group work, in which each patient with mild cognitive impairment was paired with a patient with moderate cognitive impairment. Thus, patients with mild cognitive impairment observed a series of functional exercises performed by their peers and replicated them. Simultaneously, the patients with moderate cognitive impairment replicated the movement after observing it performed by a patient with mild cognitive impairment. The control group continued to receive their usual care at the center. The upper limb function, cognitive level and function in basic activities of human daily life were measured before and after the intervention and compared with the control group., Results: statistically significant differences were found in the functionality of basic activities of daily living, in the functionality of the upper limb and in the cognitive level in all patients in the experimental group regardless of the initial cognitive level. No statistically significant differences were found in the control group., Conclusions: the implementation of a group, peer-based, action-observation learning therapeutic program is effective in improving the basic activities of human daily life, cognitive level and upper limb functionality in patients with mild and moderate dementia.

The aim of this study was to develop a Spanish Version of the Trunk Measurement Scale (TCMS-S) to analyze its validity and reliability and determine the Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) in children with Cerebral Palsy (CP). Participants were assessed twice 7-15 days apart with the TCMS-S and once with the Gross Motor Function Measurement-88 (GMFM-88), Pediatric Disability Inventory-Computer Adaptive Test (PEDI-CAT), Cerebral Palsy Quality of Life (CPQoL), and Gross Motor Classification System (GMFCS). Internal consistency was evaluated using Cronbach's alpha, and the intraclass correlation (ICC) and kappa coefficients were used to investigate the agreement between the assessments. Finally, 96 participants with CP were included. The TCMS-S showed excellent internal consistency (Cronbach's alpha = 0.95 [0.93 to 0.96]); was highly correlated with the GMFM-88 (rho = 0.816) and the "mobility" subscale of the PEDI-CAT (rho = 0.760); showed a moderate correlation with the "feeling about functioning" CPQoL subscale (rho = 0.576); and differentiated between the GMFCS levels. Excellent test-retest agreement was found for the total and subscale scores (ICC ≥ 0.94 [0.89 to 0.97). For the total TCMS-S score, an SEM of 1.86 and an MDC of 5.15 were found. The TCMS-S is a valid and reliable tool for assessing trunk control in children with CP.

Background: Fibromyalgia (FM) is defined as a chronic syndrome characterized by diffuse musculoskeletal pain, associated with characteristic signs and symptoms such as fatigue and/or sleep and mood disorders, and whose etiology, pathogenesis and prognosis may or may not be known. There is growing evidence of manual therapy as a treatment for pain in the short and medium term, also in patients affected by FM. However, the heterogeneity of the manual therapy treatments administered are a very common clinical practice, as they are based more on the judgment or tendency of the physiotherapist, rather than on clear scientific evidence. Therefore, the aim of the present study protocol will be to determine which manual therapy approach is more effective in addressing health status by improving symptoms (sensory, cognitive, emotional and social) in patients with FM., Methods: a randomized controlled clinical trial with a 3-month follow-up will be carried out with 52 female patients affected by rheumatologist-diagnosed FM will be recruited and evaluated at the Asociación de Fibromialgia y Síndrome de Fatiga Crónica (AFINSYFACRO) in Móstoles, Madrid, Spain. For more details on the protocol, a pilot study was carried out using a non-probability method of judgmental or purposive sampling. Thirteen patients were also evaluated, treated and reevaluated; eight patients were assigned to the myofascial techniques approach (MTA) group and five to the Maitland's mobilization approach (MMA) group., Results: the preliminary results presented here are intended to show how the planned randomized controlled clinical trial will develop. Patients who received MTA had significantly improved pain and health status outcomes after treatment and at 1-month follow-up, with no significant change in those who received MMA., Conclusions: the exact details of the study protocol on which the manual therapy approach is more effective in addressing health status by improving symptoms (sensory, cognitive, emotional, and social) in patients with FM are presented. Preliminary results show that manual therapy is effective in improving pain and health status in patients with fibromyalgia at short and medium term, with significant results in those who received MTA.

Introduction: COVID-19 pandemic has challenged healthcare systems worldwide. The aim of this study was to assess the results of a Respiratory Telerehabilitation Program implemented to patients post-COVID-19 in postacute phase of mild to critical course of COVID-19 who had persistent respiratory symptoms and had not received any vaccination. The intervention was performed during confinement., Methods: A quasi-experimental nonrandomized study was conducted in Spain during confinement. Respiratory Telerehabilitation Program was guided by a specialized physical therapist through a web platform (Zoom by Zoom Video Communications, San Jose, CA, USA). Participants were recruited through social webs. Outcome measures included respiratory rate, heart rate, percutaneous oxygen saturation, Mahler's Dyspnea Index, anxiety status, and quality of life [EuroQol 5 Dimension 5 (EQ-5D)]., Results: A total number of 148 participants were recruited, with a final number of 100 participants completing the protocol (50 experimental group (EG)/50 control group (CG)). A total of 500 telerehabilitation sessions were performed for this study. In the EG, pre-post intervention comparative analysis showed significative changes in Mahler's functional dyspnea ( p  < 0.001), the State-Trait Anxiety Inventory ( p  < 0.001), oxygen saturation ( p  < 0.001), heart rate ( p  < 0.001), quality-of-life questionnaire ( p  < 0.001), and respiratory rate ( p  < 0.001). Participants in the CG showed an improvement in all the variables, but the differences were not statistically significant except in Mahler's functional dyspnea ( p  = 0.001) and in the quality-of-life questionnaire ( p  = 0.043). Percentage changes in pre-post intervention were calculated and compared between EG and CG. There were statistically significative differences in all the outcomes in favor of the EG., Conclusion: The implementation of a pulmonary telerehabilitation program for COVID-19 not vaccinated survivors in postacute phase with mild to critical course of COVID-19 with respiratory sequelae has proven its benefits in cardiorespiratory variables and dyspnea-related anxiety.

The analysis of the predictive validity of a scale allows us to establish objectives in rehabilitation and to make decisions in the clinical setting. The objective of this study was to determine the validity of the Postural Assessment Scale for Stroke (PASS) to predict functionality at each stage of recovery in stroke patients. Methods: A retrospective study was carried out collecting data from patients admitted to a neurorehabilitation hospital. All patients having suffered a stroke less than two months before hospital admission were included in the study. The balance was measured with the PASS scale and the functionality with the Functional Independence Measure (FIM) scale. Simple linear regressions were performed to model the relationship between the PASS and FIM scores in the acute, subacute and chronic stages (6 and 12 months), as well as between the PASS scores at admission and the FIM values in the chronic stage. Results: The PASS scale showed a good predictive validity (R2 values from 0.54 to 0.87; β values from 1.99 to 2.62; p < 0.001) for FIM scores at acute, subacute and chronic stages, with lower goodness-of-fit for PASS scores at admission and FIM scores at 12 months (R2 = 0.383; β = 1.61 (0.96−2.26); p < 0.001). Cut-off points in the PASS scale to predict high functional level were 17.5 for the acute stage and 16.5 for the subacute and chronic stages. A score of 8.5 on the PASS scale measured in the acute phase predicted a high functional level at 12 months. Conclusion: The PASS scale is a useful tool to classify the functionality of stroke patients in the acute, subacute and chronic phases. The PASS score upon admission into the hospital can predict the functionality of the stroke patients after 12 months. However, future studies should be carried out to corroborate our findings with larger sample sizes.

Introduction: the Wisconsin Gait Scale (WGS) has been shown to be a valid and quick tool for analyzing gait in post-stroke people in the clinical setting. Its widespread use has led to versions of the scale in other languages, but so far there has been no version in Spanish., Objective: to conduct a cross-cultural adaptation of the WGS for use in the Spanish-speaking population and to analyze the content validity., Materials and Methods: the Spanish version was obtained using the double translation method and back translation method, followed by a review by an expert committee. This expert committee evaluated the content validity index (CVI) for each item on the version obtained and for the entire scale (scale content validity index (S-CVI)). The item content validity index (I-CIV) was calculated as the number of experts whose score had been 3 or 4 divided by the total number of experts. To obtain the S-CVI, the middle of the I-CVI was calculated for all the items on the scale., Results: the Spanish version of the WGS was obtained after the expert committee evaluation. The CVI was excellent for its general assessment (0.91), excellent for 85.7% of its items (≥0.78), and good for 14.3% of the CVI (≥0.72)., Conclusions: the Spanish version of the WGS was developed through a process of cross-cultural adaptation from its original English version, and, according to an expert committee, it had an excellent content validity.

(1) Background: Observational scales are the most common methodology used to assess postural control and balance in people with stroke. The aim of this paper was to analyse the construct validity of the Postural Assessment Scale for Stroke Patients (PASS) scale in post-stroke patients in the acute, subacute, and chronic stroke phases. (2) Methods: Sixty-one post-stroke participants were enrolled. To analyze the construct validity of the PASS, the following scales were used: the Functional Ambulatory Category (FAC), the Wisconsin Gait Scale (WGS), the Barthel Index (BI) and the Functional Independence Measure (FIM). (3) Results: The construct validity of the PASS scale in patients with stroke at acute phase was moderate with the FAC ( r = -0.791), WGS ( r = -0.646) and FIM ( r = -0.678) and excellent with the BI ( r = 0.801). At subacute stage, the construct validity of the PASS scale was excellent with the FAC ( r = 0.897), WGS ( r = -0.847), FIM ( r = -0.810) and BI ( r = -0.888). At 6 and 12 months, the construct validity of the PASS with the FAC, WGS, FIM and BI was also excellent. (4) Conclusions: The PASS scale is a valid instrument to assess balance in post-stroke individuals especially, in the subacute and chronic phases (at 6 and 12 months).

Background: Brain's is stimulated by Vojta Therapy through selected body areas activating stored innate motor programs which are exported as coordinate movement and muscle contractions to trunk and limbs. The aim of this pilot study is to know the responses at cortical level to a specific tactile input, assessed by electroencephalography (EEG), compared to a sham stimulation, in healthy subjects., Methods: A randomized-controlled trial was conducted. Participants were randomly distributed into two groups: a non-specific tactile input-group (non-STI-group) (n = 20) and a Vojta specific tactile input-group (V-STI-group) (n = 20). The non-STI-group was stimulated in a non specific area (quadriceps distal area) and V-STI-group was stimulated in a specific area (intercostal space, at the mammillary line between the 7th and 8th ribs) according to the Vojta therapy. Recording was performed with EEG for 10 min considering a first minute of rest, 8 min during the stimulus and 1 min after the stimulus. EEG activity was recorded from 32 positions with active Ag/AgCl scalp electrodes following the 10-20 system. The continuous EEG signal was split into consecutive segments of one minute., Results: The V-STI-group showed statistically significant differences in the theta, low alpha and high alpha bands, bilaterally in the supplementary motor (SMA) and premotor (PMA) areas (BA6 and BA8), superior parietal cortex (BA5, BA7) and the posterior cingulate cortex (BA23, BA31). For the V-STI-group, all frequency bands presented an initial bilateral activation of the superior and medial SMA (BA6) during the first minute. This activation was maintained until the fourth minute. During the fourth minute, the activation decreased in the three frequency bands. From the fifth minute, the activation in the superior and medial SMA rose again in the three frequency bands CONCLUSIONS: Our findings highlight that the specific stimulation area at intercostal space, on the mammillary line between 7 and 8th ribs according to Vojta therapy differentially increased bilateral activation in SMA (BA6) and Pre-SMA (BA8), BA5, BA7, BA23 and BA31 in the theta, low and high alpha bands in healthy subjects. These results could indicate the activation of innate locomotor circuits during stimulation of the pectoral area according to the Vojta therapy. Trial registration Retrospectively registered. This randomized controlled trial has been registered at ClinicalTrials.gov Identifier: NCT04317950 (March 23, 2020).

Objective: Vojta therapy describes stereotypic widespread motor responses as a pattern of tonic muscle contractions during a peripherical pressure stimulation. The present work proposes to characterize the responses at muscles level to a specific tactile input based on Vojta therapy, assessed by sEMG, compared to a sham stimulation in healthy subjects., Methods: Surface electromyography (sEMG) signal was acquired with dipolar electrodes placed at wrist extensors of both forearms, right tibialis anterior, and top part of rectus abdominus, ground channel placed over the right olecranon. It was amplified and digitized by a 4-channel hub Biosignalsplux device (Plux Wireless Biosignals S.A., Lisboa, Portugal), sampled at 1000 Hz with 16-bit per channel. A continuous 10-minute record of the sEMG signal from the four electrodes were registered. Resting EEG during the first minute before the stimulation period was recorded by 64 active electrodes., Results: Statistically significant differences were showed between sham and experimental group. Experimental group participants were subjected to cluster analysis based on their muscle activation patterns, generating three different models of activation. Differences in the previous resting cortical activity in left superior frontal area were found between clusters that activated limb muscles and the cluster that did not., Conclusions: Vojta specific stimulation area activates innate muscle responses assessed by sEMG in healthy subjects, compared to a sham stimulation., Significance: This characterization might be helpful to the prescription and application of Vojta therapy in an individual-basis for non-neurophysiologically damaged adult subjects.
