Is more always better? Effectiveness of constraint-induced movement therapy in children with high-risk or unilateral cerebral palsy (0-6 years): Systematic review and meta-analysis

BACKGROUND

While constraint-induced movement therapy is strongly recommended as an intervention for infants with unilateral cerebral palsy, the optimal dosage remains undefined. This systematic review aims to identify the most effective level of intensity of constraint-induced movement therapy to enhance manual function in infants at high risk of asymmetric brain lesions or unilateral cerebral palsy diagnosis.

METHODS

This systematic review with meta-analysis encompassed a comprehensive search across four electronic databases to identify articles that met the following criteria: randomised controlled trials, children aged 0-6 with at high risk or with unilateral cerebral palsy, and treatment involving constraint-induced movement therapy for upper limb function. Studies with similar outcomes were pooled by calculating the standardised mean difference score for each subgroup, and subgroups were stratified every 30 h of total intervention dosage (30-60, 61-90, >90 h). Risk of bias was assessed with Cochrane Collaboration's tool.

RESULTS

Seventeen studies were included. Meta-analyses revealed significant differences among subgroups. The 30-60 h subgroup showed a weak effect for spontaneous use of the affected upper limb during bimanual performance, grasp function, and parents' perception of how often children use their affected upper limb. Additionally, this subgroup demonstrated a moderate effect for the parents' perception of how effectively children use their affected upper limb.

CONCLUSIONS

Using a dosage ranging from 30 to 60 h when applying a constraint-induced movement therapy protocol holds promise as the most age-appropriate and cost-effectiveness approach for improving upper limb functional outcomes and parent's perception.

Modifications in family centered developmental care and in neonatal intensive care during the COVID-19 pandemic in a hospital in Spain: A qualitative study

INTRODUCTION

Family centered developmental care (FCDC) are a philosophy of care in the neonatal care units (NICU), based on the control of sensory stimulation the adequate position and of newborn and the family involvement of cares. Nursing staff are the main providers of this care. Sanitary measure to control of the COVID-19, such as the use of masks, isolation of positive cases and capacity limit, conditioned the implementation of FCDC.

OBJECTIVES

To understand the meaning of the experience of the nursing staff of a neonatal intensive care unit (NICU) on the implementation of the FCDC, under the sanitary measures imposed for the containment of COVID-19.

METHODS

A qualitative study was conducted from the descriptive phenomenological paradigm in which NICU nurses were recruited. The qualitative data collection was carried out through open-ended and semi-structured interviews. These were analyzed respectively through a preliminary narrative analysis and a thematic analysis of the informant nurses' narratives and discourses.

RESULTS

Three open-ended and 7 semi-structured interviews were conducted from which three main topics emerged: 1) changes in the FCDC derived from the sanitary restrictions implemented for the containment of COVID-19; 2) changes in interpersonal relationships in the context of a pandemic, and 3) transition to normality.

CONCLUSIONS

The nurses of NICU perceived changes in the implementation of the FCDC due to the containment of COVID-19, that modified the relationship with the parents of NB, accelerating their training as caregivers, and involved the implementation of new measures such as video calls.

Relationship between Female Sexual Dysfunction and Trunk Stability Post-Stroke: A Cross-Sectional Study

Background and Objectives: Stroke can lead to a variety of consequences, the severity and nature of which are contingent upon the affected brain region or lesion type. These consequences manifest with distinct clinical presentations and recovery trajectories. This study aims to investigate the potential correlation between feminine sexual dysfunction and trunk stability among stroke survivors. Materials and Methods: Thirty-eight women (stroke group n = 19 and control group n = 19) were recruited. A cross-sectional observational study was designed. Outcome measures were recorded using the Feminine Sexual Function Index, the National Institute of Health Stroke Score, the Newcastle Stroke-specific Quality of Life Measure Beck Depression Index, the Barthel Index, the Urge-urinary Distress Inventory, and the Trunk Impairment Scale. Spearman's correlation was tested between different factors influencing feminine sexual dysfunction and trunk stability. Results: Statistically significant differences were found in sexual function between the stroke group versus the control group (Z = 88; p = 0.007; rb = 0.51). The correlation showed a relationship between feminine sexual dysfunction and trunk stability (p < 0.05). A relationship between quality of life and sexual dysfunction was also found (p < 0.05). There were no statistically significant results for the association between dependency, severity of stroke, time after stroke type of stroke, and sexual dysfunction (p = 0.378). Conclusions: The results of this study support the existence of a correlation between feminine sexual dysfunction and trunk stability, probably due to trunk and pelvic floor muscle synergy. Multidisciplinary teams assessing sexual dysfunction after stroke should include a physical therapist to assess the physical components that may interfere with feminine sexual health post-stroke.

Effectiveness of motor imagery in complex regional pain syndrome: A systematic review with meta-analysis

OBJECTIVE

The purpose of this study was to determine the effects of motor imagery (MI) on pain intensity and disability in individuals with complex regional pain syndrome (CRPS).

METHODS

A systematic search was conducted in various electronic databases to identify all relevant studies: PubMed, CINAHL, WOS, PEDro, CENTRAL, and Scopus. Randomized controlled trials assessing the effects of MI in individuals with CRPS were included. The risk of bias was assessed with the Cochrane Risk of Bias tool, the methodological quality was evaluated using PEDro scale, and the level of evidence was reported according to the GRADE. Between-groups standardized mean differences (SMD) were calculated.

RESULTS

Six studies were included. The meta-analysis found moderate-quality evidence that MI improves pain intensity and related disability as immediate (pain: SMD -1.07, 95% CI: -1.53 to -0.60; disability: SMD 1.05, 95% CI: 0.59 to 1.51), short-term (pain: SMD -1.28, 95% CI: -2.14 to -0.42; disability: SMD 1.37; 95% CI: 0.16 to 2.58), and long-term effects (pain: SMD -1.18; 95% CI: -1.89 to -0.46; disability: SMD 1.18; 95% CI: 0.46 to 1.89), as compared with a comparison group. The risk of bias of the trials was relatively low, but the imprecision of the results downgraded the level of evidence.

CONCLUSIONS

Moderate-quality evidence suggests a positive effect of MI for improving pain intensity and disability immediately after and at short-term in individuals with CRPS.

Spanish adaptation and validation of the child- and parent-report cystic fibrosis questionnaire-revised (CFQ-R)

OBJECTIVE

To evaluate the psychometric properties of the Spanish versions of the child- and parent-report cystic fibrosis questionnaire-revised (CFQ-R).

METHODS

A Spanish adaptation of the CFQ-R was performed; 68 children with CF (6-13 years) and their parents completed the child- and parent-report CFQ-R, respectively, and the Revidierter KINDer Lebensqualitätsfragebogen (KINDL) questionnaire. The CFQ-R was completed twice, 7-10 days apart, and its psychometric properties were analyzed.

RESULTS

The internal consistency of both CFQ-R versions was adequate (child-report version, Cronbach's α >.60 for all domains except "Treatment Burden" [α = .42] and "Social Functioning" [α = .57]; parent-report version, α > .60 for all domains except "Social Functioning" [α = .58]). For the child-report version, the lowest measurement error was for "Emotional Functioning" (standard error of measurement [SEM]: 8.3%; minimal detectable change [MDC90 ]: 19.3%), and the highest was for "Body Image" (SEM: 15%; MDC90 : 35%). For the parent-report version, the lowest measurement error was for "Physical Functioning" (SEM: 7.1%; MDC90 : 16.5%), and the highest was for "Weight" (SEM: 17.2%; MDC90 ; 40.1%). The correlation between the versions showed higher agreement for the domains related to observable signs ("Physical Functioning") and lower agreement for "Emotional Functioning." There was a significant correlation between the CFQ-R and KINDL.

CONCLUSION

Both the child- and parent-report versions of the Spanish CFQ-R have adequate reliability and validity for clinical and research purposes. These versions can be administered before and after starting modulator therapy to assess its effect on daily functioning. The MDC90 can help identify, with a high probability, whether real changes have occurred in the quality-of-life subscales in children with CF.

Natural Semantic Networks of the Neurorehabilitation Concept by Spanish Physiotherapists-A Qualitative Phenomenological Representational Study

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.

Validation of the Spanish version of the Pain Catastrophizing Scale for Children (PCS-C)

INTRODUCTION

Pain catastrophizing is a powerful factor that can affect health care outcomes as well as emotional and physical well-being. The Pain Catastrophizing Scale for Children (PCS-C) is widely used, but it is not validated in Spanish. The aim of the study was to translate the PCS-C to Spanish and assess the validity and reliability of the translated version.

PATIENTS AND METHODS

This study was carried out in two phases: (a) instrument translation (via a translation-back-translation process) and (b) psychometric analysis (construct validity: exploratory and confirmatory factor analysis, internal consistency, floor and ceiling effects and convergent validity). It had a cross-sectional design and was conducted on a sample of children aged 8-18 years was selected by convenience in a paediatric hospital. The study followed the STARD checklist.

RESULTS

The sample included 150 children and adolescents (mean age, 12.45 years; 63.8% male) and their parents. The exploratory and the confirmatory analysis showed a good adjustment of the model to the original 3-model structure with 13 items. The internal consistency of the scale was excellent (Cronbach α, 0.904), and no floor or ceiling effects were detected. In the convergent validity analysis, the Spanish version of the PCS-C showed a moderate correlation with pain interference (r=0.400) and with health-related quality of life (r=0.217-0.303).

CONCLUSIONS

These results show that the Spanish version of the PCS-C is a valid and reliable scale to assess pain catastrophizing in children and adolescents.

Psychometric Properties and Clinical Usefulness of the Spanish Version of the Toe Walking Tool

BACKGROUND

The Toe Walking Tool (TWT) was developed in Australia as a valid and reliable screening tool for children who toe-walk. However, psychometric properties of the Spanish version of the TWT have not been studied. The aim of this study was to assess psychometric properties and clinical usefulness of the Spanish version of the TWT.

METHODS

A cross-sectional study was conducted. Twelve children were assessed with the TWT. Intrarater and interrater reliability and agreement were calculated using the intraclass correlation coefficient (ICC) and the Fleiss kappa method for multiple raters. Internal consistency and construct validity were assessed with the Kuder-Richardson formula 20 coefficient and known-group methods, respectively. Sensitivity and specificity were analyzed using the receiver operating characteristic curve. The Content Validity Index was calculated to determine clinical usefulness.

RESULTS

An excellent intrarater (ICC = 1) and interrater reliability (ICC = 0.8), moderate interrater agreement (Fleiss kappa, 0.6), strong internal consistency (Kuder-Richardson formula 20 coefficient, 0.86), and very good construct validity were found. Sensitivity and specificity results were appropriate (area under the curve, 0.845). The Content Validity Index was 0.906, suggesting high usefulness.

CONCLUSIONS

The Spanish version of the TWT was found to be a valid, reliable and useful screening tool for children who toe-walk, providing evidence for its recommendation.

Spanish adaptation and validation of the empowerment of parents in the intensive care-neonatology (EMPATHIC-N) questionnaire

INTRODUCTION

Parental satisfaction is rarely measured in the neonatal intensive care unit due to a lack of specific assessment tools. The Empowerment of Parents in The Intensive Care-Neonatology (EMPATHIC-N) questionnaire is an instrument to assess satisfaction in relation to family-centred care that has been validated in several countries, but not Spain.

OBJECTIVES

To perform the translation and cultural adaptation of the EMPATHIC-N to Spanish followed by its validation for the purpose of assessing satisfaction in parents with children admitted to the neonatal intensive care unit.

MATERIAL AND METHODS

The questionnaire first underwent forward and backward translation and transcultural adaptation by a panel of experts through a standardized process based on the Delphi method, followed by a pilot study in 8 parents and then a cross-sectional study in the neonatal intensive care unit of a tertiary care hospital to assess the reliability and converging validity of the Spanish version.

RESULTS

The study proved the comprehensibility, validity, feasibility, applicability and usefulness of the Spanish version of the EMPATHIC-N in the field of paediatric health after being evaluated by 19 professionals and 60 parents. The content validity was found to be excellent (0.93). The reliability and convergent validity of the Spanish version of the EMPHATIC-N was analysed in a sample of 65 completed questionnaires. The Cronbach α for each domain was greater than 0.7, indicating a high internal consistency. We assessed validity by analysing the correlation of the 5 domains with the with the 4 general satisfaction items. The validity was found to be adequate (rs, 0.4-0.76; P < .01).

CONCLUSIONS

The Spanish version of the EMPATHIC-N questionnaire is a comprehensible, useful, valid and reliable instrument to measure satisfaction in the parents of children admitted to neonatal care units.

Cross-cultural adaptation and psychometric properties of Spanish Child Pain Anxiety Symptoms Scale

INTRODUCTION

Pain anxiety is a psychological component that can regulate and modulate the experience of pain in children and adolescents. It can also have an impact on the outcomes of surgical procedures, chronic pain management and psychological interventions. The aim of our study was to translate the Child Pain Anxiety Symptoms Scale (CPASS) into Spanish and assess the psychometric properties of the Spanish version.

PATIENTS AND METHODS

First, the CPASS was translated according to international guidelines. Secondly, to assess the psychometric properties of the translated version, we conducted an analysis in a paediatric sample. A total of 160 children, 49.37% female, with a mean age of 14.5 years (SD, 2.3; range, 8-18 years) completed pain catastrophising, health-related quality of life, pain interference and pain intensity scales. We assessed the following psychometric properties: construct validity (exploratory and confirmatory factor analysis), internal consistency, floor and ceiling effects and convergent validity (correlation of CPASS to the other completed questionnaires completed and with objective aspects of the health history).

RESULTS

In the exploratory factor analysis, the final 18-item version (having excluded items 18 and 19) of the CPASS was the best fit, with all items included in the hypothetical construct and exhibiting optimal factor loadings. The confirmatory factor analysis showed that the final 18-item, 4-factor model was adequate for the scale structure. We did not detect any floor or ceiling effects in the final version. Lastly, the results confirmed that the Spanish version has good internal consistency (Cronbach  α, 0.88) and an adequate convergent validity.

CONCLUSION

The Spanish CPASS exhibits good psychometric proprieties and it can be used to assess pain anxiety in the paediatric population.

Differences between Novice and Expert Raters Assessing Trunk Control Using the Trunk Control Measurement Scale Spanish Version (TCMS-S) in Children with Cerebral Palsy

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.

Mobile Applications for Resting Tremor Assessment in Parkinson’s Disease: A Systematic Review

(1) Background: Resting tremor is a motor manifestation present in most Parkinson’s disease (PD) patients. For its assessment, several scales have been created, but mobile applications could help in objectively assessing resting tremor in PD patients in person and/or remotely in a more ecological scenario. (2) Methods: a systematic review following the PRISMA recommendations was conducted in scientific databases (PubMed, Medline, Science Direct, Academic Search Premier, and Web of Science) and in the main mobile application markets (Google Play, iOS App Store, and Windows Store) to determine the applications available for the assessment of resting tremor in patients with PD using only the measurement components of the phone itself (accelerometers and gyroscopes). (3) Results: 14 articles that used mobile apps to assess resting tremor in PD were included, and 13 apps were identified in the mobile application markets for the same purpose. The risk of bias and of applicability concerns of the articles analyzed was low. Mobile applications found in the app markets met an average of 85.09% of the recommendations for the development of medical mobile applications. (4) Conclusions: the use of mobile applications for the evaluation of resting tremor in PD patients has great potential, but validation studies for this purpose are scarce.

Trunk Control Measurement Scale (TCMS): Psychometric Properties of Cross-Cultural Adaptation and Validation of the Spanish Version

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.

Imagined Timed Up and Go test (iTUG) in people with Parkinson's Disease: test-retest reliability and validity

PURPOSE

To determine the test-retest reliability and validity of the Imagined Timed Up and Go Test (iTUG) as a Motor Imagery measure of temporal accuracy in people with Parkinson's Disease (PD).

MATERIALS AND METHODS

A descriptive study was conducted following the GRRAS recommendations. Thirty-two people with idiopathic, mild to moderate PD (Hoehn and Yahr I-III), without cognitive impairment (MMSE ≥ 24), were assessed twice (7-15 days apart) with the iTUG. The absolute unadjusted difference in seconds, and the absolute adjusted difference as percentage of estimation error, between real and imagined TUG times, were calculated as outcome measures. Test-retest reliability was assessed using a two-way mixed-effects model of the ICC. Construct validity was tested with the Imagined Box and Blocks Test (iBBT) and convergent validity with clinical characteristics of PD, using the Spearman's rank correlation coefficient.

RESULTS

The ICC for the unadjusted and adjusted measures of the iTUG was ICC = 0.61 and ICC = 0.55, respectively. Correlations between iTUG and iBBT were not statistically significant. The iTUG was partially correlated to clinical characteristics of PD.

CONCLUSIONS

Test-retest reliability of the iTUG was moderate. Construct validity between iTUG and iBBT was poor, so caution should be taken when using them concurrently to assess imagery's temporal accuracy.

Systematic review on the effectiveness of cognitive multisensory rehabilitation

Cognitive multisensory rehabilitation (CMR) -a therapeutic approach to help recover movement using neurocognitive exercises- activates patient's perceptive and cognitive processes, key for motor learning. The aim of this systematic review was to assess the effectiveness of CMR on motor function and quality of life and compare the findings with other rehabilitation approaches or no-intervention in neurological and trauma adult and pediatric patients. We carried out a systematic review of randomized controlled clinical trials, pilot studies, and case series in PubMed, PEDro, Cochrane Library, and the CINHAL Complete database published between 2012 and 2021. Ten studies met the eligibility criteria. CMR provides similar or superior benefits compared to other types of approaches for the restoration of upper limb function, gait, balance, and quality of life in neurological and trauma patients. Further research with larger samples and higher methodological quality need to be developed to de-termine its long-term effectiveness.

Development of the Web-Based Spanish Version of the Barthel Index in Patients with Multiple Sclerosis

BACKGROUND

The aims of this study were to develop a web-based Spanish form of the Barthel index (BI), to evaluate its psychometric properties and stability over time (test-retest), and to determine minimal detectable change (MDC) in patients with multiple sclerosis (MS).

METHODS

Participants answered the BI on two forms (web-based and face-to-face interview), 7-10 days apart. The internal consistency was evaluated using Cronbach's alpha, and intraclass correlation (ICC) and kappa (κ) coefficients were used to investigate the agreement between both forms.

RESULTS

143 participants were included. The Spanish web-based form of the BI showed excellent agreement between both forms for each item (κ = 0.86 (0.79 to 0.92), and for total score (κ = 0.87 (0.81 to 0.93); ICC = 0.99 (0.98 to 0.99). The internal consistency was good-excellent (Cronbach's alpha = 0.89 (0.86-0.91)). The stability over time was adequate, the agreement of each item was κ = 0.63 (0.52-0.74)), and for total score (ICC = 0.97), determining a MDC₉₅ of 12.09 points.

CONCLUSIONS

The Spanish web-based form of the BI is a valid and reliable tool to assess functionality and can be applied in both formats in patients with MS. A total score difference of more than 12 points was found to indicate a deterioration or improvement in the patient's functionality.

Validity and reliability of Spanish PROMIS pediatric pain interference short form

BACKGROUND

The goal of this study was to analyze psychometric properties of the Spanish PROMIS Pediatric Pain Interference short form (PROMIS-PPI) in a sample of Spanish children and adolescents.

METHODS

In a hospital pediatric sample it was studied the structure scale (exploratory and confirmatory analysis), construct validity, convergent validity, and reliability (internal consistency).

FINDINGS

163 children and adolescents (mean age 13.3 years; SD 2.01; 39.26% female) with and without chronic pain completed measures pertaining to their pain experience. Psychometric analysis showed the PROMIS-PPI Spanish version maintains the original one-factor model of the scale, excellent internal consistency (Cronbach's α coefficient 0.90 (95% CI 0.88-0.92)), and convergent validity (showed a positive, significant, and moderate magnitude correlation [r from 0.330 to 0.604] with pediatric quality of life, child and parent pain intensity, and showed a low correlation with the number of medical consultations in the last year).

DISCUSSION

The Spanish PROMIS-PPI scale is a valid and reliable tool. It is recommended for research and clinical care in pediatric populations.

APPLICATION TO PRACTICE

The results provide evidence that the Spanish version of PROMIS-PPI is valid and reliable tool. Health professionals who work with children in risk to develop persistent pain, will have access to short tool with highest evidence, for assess pain interference.

Effectiveness of mirror therapy and action observation therapy in infantile cerebral palsy: a systematic review

The aim of this review was to assess the effectiveness of mirror therapy (MT) and action observation therapy (AOT) on upper limb-related body structures, body functions, activity, and involvement in patients with infantile cerebral palsy (ICP). We carried out a systematic review of randomized controlled trials published over the past 10 years, in which MT or AOT was compared to other ICP-directed interventions. Nine studies met the inclusion criteria and we measured their methodological quality using the PEDro scale. MT or AOT seem to significantly improve upper limb-related body structures, body function, activity, and participation in comparison to other interventions for ICP. Both seem to improve overall quality of life, reduce their disability, and promote its functioning. Further studies with higher methodological quality need to be developed to confirm the long-term effectiveness of MT and AOT.

Negative Psychological Factors' Influence on Delayed Onset Muscle Soreness Intensity, Reduced Cervical Function and Daily Activities in Healthy Participants

We examined the influence of negative psychological factors (catastrophizing, distress and kinesiophobia) on delayed onset muscle soreness (DOMS) intensity, cervical function (strength and range of motion) and on daily activities (ADL), and the suitability of an exercise protocol designed to induce DOMS within the cervical region. Psychological factors and cervical function were assessed in 86 healthy participants at baseline before applying a DOMS provocation protocol in the cervical flexor muscles. After 24hour, cervical function was reassessed. In addition, at 24hour and 48hour, the intensity of DOMS and its impact on ADL were assessed using the visual analog scale (VAS). The protocol was effective given that it generated low-moderate intensity DOMS (VAS≈30 -40mm) and a statistically significant reduction in cervical strength and range of motion. Psychological distress (anxiety and depression), but not kinesiophobia and catastrophism, predicted a loss of cervical strength (explained 43% of the variance) and range of motion (explained 22% of the variance) after induction of DOMS. In addition, participants' anxiety level predicted DOMS intensity at 24hour (explained 19% of the variance). PERSPECTIVE: The present findings highlight the relevance of evaluating psychological distress as a preventive/therapeutic measure, given that high levels of distress could lead to more intense and disabling pain in acute injuries, and all these aspects are considered risk factors for the chronification of symptoms.

Physical Function in Amateur Athletes with Lumbar Disc Herniation and Chronic Low Back Pain: A Case-Control Study

This study aimed to analyze if chronic low back pain (LBP) and lumbar disc herniation induce biomechanics, flexibility, body balance, physical activity, and muscular function alterations compared to a similar asymptomatic cohort. Fifty male volunteers (n = 25 with chronic LBP and lumbar disc herniation and n = 25 pain-free subjects) were enrolled. Range of motion (internal and external hip rotation, ankle dorsiflexion, and active straight leg raise, ASLR), trunk flexibility (finger−floor distance), body balance (Y-balance test) and muscle function (Biering−Sorensen test, prone and lateral bridges) outcomes were assessed. Comparative analyses between sides and group were conducted. Results: Patients showed greater weight and BMI compared with controls (p < 0.05). None of the outcomes bilaterally assessed showed side-to-side differences for pain-free participants (all, p > 0.05) or LBP patients (all, p > 0.05). Regarding the differences between groups, LBP patients showed limited internal hip rotation (p < 0.001), finger−floor distance (p < 0.001), body balance (p < 0.001), and muscle endurance (planks p < 0.001; Biering−Sorensen test p < 0.05). External hip rotation, ASLR, and ankle dorsiflexion range of movement were comparable in both groups (p > 0.05). The sample of pain-free amateur athletes showed greater range of movement for internal hip rotation, lower finger−floor distance, better body balance, and muscle function. However, the external hip rotation, ankle dorsiflexion, and ASLR tests showed no difference between cases and controls.

Citation Network Study on the Use of New Technologies in Neurorehabilitation

New technologies in neurorehabilitation is a wide concept that intends to find solutions for individual and collective needs through technical systems. Analysis through citation networks is used to search scientific literature related to a specific topic. On the one hand, the main countries, institutions, and authors researching this topic have been identified, as well as their evolution over time. On the other hand, the links between the authors, the countries, and the topics under research have been analyzed. The publications analysis was performed through the Web of Science database using the search terms "new technolog*," "neurorehabilitation," "physical therapy*," and "occupational therapy*." The selected interval of publication was from 1992 to December 2020. The results were analyzed using CitNetExplorer software. After a Web of Science search, a total of 454 publications and 135 citation networks were found, 1992 being the first year of publication. An exponential increase was detected from the year 2009. The largest number was detected in 2020. The main areas are rehabilitation and neurosciences and neurology. The most cited article was from Perry et al. in 2007, with a citation index of 460. The analysis of the top 20 most cited articles shows that most approach the use of robotic devices and brain-computer interface systems. In conclusion, the main theme was found to be the use of robotic devices to address neuromuscular rehabilitation goals and brain-computer interfaces and their applications in neurorehabilitation.

[Postural control and gait changes in subacute stroke patients after receiving interdisciplinary rehabilitation and related factors: a retrospective study]

INTRODUCTION

Although early post-stroke rehabilitation is essential to optimize recovery, its effects and prognostic factors are yet under discussion.

OBJECTIVE

To assess postural control and gait changes in post-stroke patients who underwent interdisciplinary rehabilitation in subacute phase and evaluate potential associated factors.

PATIENTS AND METHODS

An observational retrospective study that analyzed sociodemographic and clinical data, including Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS), Functional Ambulatory Categories (FAC) and Tinetti scale, at admission and two months after rehabilitation.

RESULTS

Data were collected from 63 patients with stroke in subacute phase. Interdisciplinary rehabilitation had a moderate and relevant clinical impact (p < 0,01; d mayor de 0,5) in postural control and gait. Ambulatory rehabilitation, psychotropic medication absence and dislipemia absence were moderate associated factors (p < 0,05; d mayor de 0,5) with a greater evolution in postural control measured with TIS and PASS. TIS at admission showed significant association with all scales' results at two months after rehabilitation, except with PASS changing posture subscale.

CONCLUSIONS

Interdisciplinary rehabilitation promotes moderate and clinically relevant changes in postural control and gait recovery in subacute stroke patients, after two-month rehabilitation period. Ambulatory rehabilitation, dyslipidemia absence and psychotropic medication absence were associated with patients' evolution, but further research is required to confirm their actual influence in larger samples.

[Effectiveness of respiratory physiotherapy combined with postural education in children with chronic neurological diseases]

BACKGROUND

Children with chronic neurological diseases present motor disability and increased respiratory morbidity and mortality. The aim of this study was to assess whether children with chronic neurological impairment benefit from respiratory physiotherapy and postural hygiene.

METHODS

Quasi-experimental study in which six fortnightly respiratory physiotherapy sessions and workshops on postural hygiene were carried out on children aged 0 to 6 years with chronic neurological disease and respiratory impairment. A PedsQL questionnaire assessed respiratory clinical variables, expectorated secretions, respiratory exacerbations and quality of life. Assessments were performed at baseline, post-intervention, and at a 3-month follow-up.

RESULTS

After physiotherapy sessions, all participants (n=30) experienced a significant (p<0.001) improvement in average oxygen saturation (94.37 to 98.3%), heart rate (126.03 to 103.6 beats/minute) and respiratory rate (42.13 to 34.27 breaths/minute), as well as a decrease in secretions (from 45.33 to 28.17 mL). This improvement was maintained after a 3-month follow-up. The average respiratory exacerbations decreased (p<0.001) compared to the previous six months: hospitalizations (from 1.6 to 0.5), visits to the emergency department (from 2.59 to 1.53) and to primary care Pediatric consultations (from 7 to 5.03). The mean score on the PedsQL questionnaire demonstrated a significant increase (p<0.001) in the quality of life after the intervention for physical (27%, to 73.4) and mental health (12%, to 70.09%).

CONCLUSION

Respiratory physiotherapy combined with postural hygiene is effective for the clinical status and quality of life in children with chronic neurological diseases, and therefore could be introduced in habitual clinical practice.

Spanish translation and validation of the Scale for Contraversive Pushing to measure pusher behaviour

INTRODUCTION

The aim of this study was to develop and validate a Spanish-language version of the Scale for Contraversive Pushing, used to diagnose and measure pusher behaviour in stroke patients.

METHODS

Translation-back translation was used to create the Spanish-language Scale for Contraversive Pushing; we subsequently evaluated its validity and reliability by administering it to a sample of patients. We also analysed its sensitivity to change in patients identified as pushers who received neurological physiotherapy.

RESULTS

Experts indicated that the content of the scale was valid. Internal consistency was very good (Cronbach's alpha of 0.94). The intraclass correlation coefficient showed high intra- and interobserver reliability (0.999 and 0.994, respectively). The Kappa and weighted Kappa coefficients were used to measure the reliability of each item; the majority obtained values above 0.9. Lastly, the differences between baseline and final evaluations of pushers were significant (paired sample t test), showing that the scale is sensitive to changes obtained through physical therapy.

CONCLUSIONS

The Spanish-language version of the Scale for Contraversive Pushing is valid and reliable for measuring pusher behaviour in stroke patients. In addition, it is able to evaluate the ongoing changes in patients who have received physical therapy.

Quality of life and exercise tolerance tools in children/adolescents with cystic fibrosis: Systematic review

INTRODUCTION

This systematic review aims to analyze the validity and reliability of available tools to assess health-related quality of life (HRQoL) and exercise tolerance in children and adolescents with cystic fibrosis (CF).

MATERIALS AND METHODS

A review of observational studies studying the validity and reliability of the tools was conducted. The COSMIN (COnsesus-based Standards for the selection of health Measurements INstruments) guide was followed to analyze the quality of these tools.

RESULTS

A total of 18 studies were selected. Of the eight HRQoL tools, five generic and three specific, analyzed in 14 studies, the Cystic Fibrosis Questionnaire-Revised (CFQ-R) presents the best properties. Of the four tools analyzed to assess exercise tolerance, cycle ergometry and the modified shuttle test are the most valid and reliable.

CONCLUSIONS

The CFQ-R, cycloergometry and the modified shuttle test have the best properties for the assessment of children with CF, but more studies are needed.

Dry Needling versus Trigger Point Injection for Neck Pain Symptoms Associated with Myofascial Trigger Points: A Systematic Review and Meta-analysis

OBJECTIVE

To examine the effects of dry needling against trigger point (TrP) injections (wet needling) applied to TrPs associated with neck pain.

METHODS

Electronic databases were searched for randomized clinical trials where dry needling was compared to TrP injections (wet needling) applied to neck muscles and collected outcomes on pain or related-disability. Secondary outcomes consisted of pressure pain thresholds, cervical mobility, and psychological factors. The Cochrane risk of bias (RoB) tool, the Physiotherapy Evidence Database (PEDro) score, and GRADE approach were used.

RESULTS

Six trials were included. TrP injection reduced pain intensity (MD -2.13, 95%CI -3.22 to -1.03) with a large effect size (SMD -1.46, 95%CI -2.27 to -0.65) as compared to dry needling. No differences between TrP injection and dry needling were found for pain-related disability (MD 0.9, 95%CI -3.09 to 4.89), pressure pain thresholds (MD 25.78kPa, 95%CI -6.43 to 57.99kPa), cervical lateral-flexion (MD 2.02° 95%CI -0.19° to 4.24°) or depression (SMD -0.22, 95%CI -0.85 to 0.41). The RoB was low, but the heterogenicity and imprecision of results downgraded the evidence level.

CONCLUSION

Low evidence suggests a superior effect of TrP injection (wet needling) for decreasing pain of cervical muscle TrPs at short-term as compared to dry needling. No significant effects on other outcomes (very low-quality evidence) were observed.

LEVEL OF EVIDENCE

Therapy, level 1a.

[Effectiveness of motor imagery in patients with multiple sclerosis: a systematic review]

INTRODUCTION

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. Motor imagery (MI) has been proposed as a treatment to improve gait, fatigue and quality of life in these dysfunctions.

AIM

To assess the effectiveness of MI, action observation therapy or mirror therapy approaches compared to other rehabilitation modality or no intervention, in MS.

DEVELOPMENT

A systematic review of randomized controlled trials was conducted. Studies published in the last ten years investigating MI versus other interventions or no intervention in patients with MS were included. PEDro scale was used to assess methodological quality of included studies. Eight studies met the eligibility criteria. For fatigue, the MI and its combination with relaxation seem to be superior compared with other types of interventions or no intervention. The MI combined with music also showed significant improvements in gait and quality of life (QoL).

CONCLUSIONS

MI and its combination with relaxation exercises have been shown to be effective in the treatment of fatigue, gait, balance, depression and QoL in patients with MS. The action observation therapy is useful in upper limb rehabilitation and improvement in attention, executive control and activation of sensorimotor networks. Further research with high methodological quality is needed to support these findings and to evaluate their effectiveness in long term.

Translation and Validation of the Spanish Movement Imagery Questionnaire Revised Second Version (MIQ-RS)

BACKGROUND

Motor imagery, which emphasizes mental rehearsal of motor skills to improve function, is frequently used in clinical practice. Because of its increasing use, reliable and valid tools are necessary to evaluate motor imagery abilities. However, there are few questionnaires translated and validated into Spanish language.

OBJECTIVE

To translate, transculturally adapt, and validate the Spanish version of the Movement Imagery Questionnaire-Revised Second Version (MIQ-RS).

DESIGN

A single-center observational study.

SETTING

University community.

PARTICIPANTS

One hundred fifty-five healthy participants were recruited.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Spanish translation of the MIQ-RS and psychometric performances of the questionnaire were tested using concurrent-criterion and content validity, construct validity, internal consistency, and test-rest reliability. Internal consistency, concurrent-criterion validity, construct validity, and test-rest reliability were assessed with Cronbach´s alpha, Spearman´s correlation coefficient, confirmatory factor analysis, and intraclass correlation coefficient (ICC), respectively.

RESULTS

Results showed satisfactory internal consistency (Cronbach α = 0.90), test-rest reliability (ICC for visual items = 0.844 and for kinesthetic items = 0.70) and content and criterion-concurrent validity (Spearman´s correlation coefficient for visual items, 0.60 and for kinesthetic items, 0.81) of the MIQ-RS Spanish version. The two-factor structure was supported by confirmatory factor analysis. Statistically significant gender differences were observed in mean kinesthetic motor imagery scores and in mean visual motor imagery scores according to sports practice. No significant differences for gender, age, and sports, musical, and dance practice were reported.

CONCLUSIONS

The Spanish version of the MIQ-RS is a valid and reliable tool to assess motor imagery abilities in healthy young people.

Effects of Adding Motor Imagery to Early Physical Therapy in Patients with Knee Osteoarthritis who Had Received Total Knee Arthroplasty: A Randomized Clinical Trial

OBJECTIVE

To investigate the effects of the inclusion of motor imagery (MI) principles into early physical therapy on pain, disability, pressure pain thresholds (PPTs), and range of motion in the early postsurgical phase after total knee arthroplasty (TKA).

METHODS

A randomized clinical trial including patients with knee osteoarthritis who have received TKA was conducted. Participants were randomized to receive five treatment sessions of either physical therapy with or without MI principles in an early postsurgical phase after a TKA (five days after surgery). Pain intensity (visual analog scale [VAS], 0-100), pain-related disability (short-form Western Ontario McMaster Universities Osteoarthritis Index [WOMAC], 0-32), pressure pain thresholds (PPTs), and knee range of motion were assessed before and after five daily treatment sessions by an assessor blinded to the subject's condition.

RESULTS

Twenty-four participants completed data collection and treatment. The adjusted analysis revealed significant group*time interactions for WOMAC (F = 17.29, P = 0.001, η2 = 0.48) and VAS (F = 14.56, P < 0.001, η2 = 0.45); patients receiving physiotherapy and MI principles experienced greater improvements in pain (Δ -28.0, 95% confidence interval [CI] = -43.0 to -13.0) and pain-related disability (Δ -6.0, 95% CI = -8.3 to -3.7) than those receiving physiotherapy alone. No significant group*time interactions for knee range of motion and PPTs were observed (all, P  > 0.30).

CONCLUSIONS

The application of MI to early physiotherapy was effective for improving pain and disability, but not range of motion or pressure pain sensitivity, in the early postsurgical phase after TKA in people with knee osteoarthritis.

Construct validity and test-retest reliability of a free mobile application for spatio-temporal gait analysis in Parkinson's disease patients

BACKGROUND

Mobile applications may be used to assess gait pattern deviation through mobile smartphones in people with Parkinson's disease (PD). However, few studies have investigated their psychometrics properties.

RESEARCH QUESTION

To study the construct validity and test-retest reliability of the RUNZI® free mobile application in people with mild to moderate PD.

METHODS

Thirty individuals were evaluated with the RUNZI® app and with the 10-meter walking test (10 MW), simultaneously. In addition, the Timed Up & Go test (TUG), Tinetti scale, and the Berg Balance Scale (BBS) were used to study the construct validity. Also, test-retest reliability of the mobile for spatio-temporal gait parameters was explored.

RESULTS

The correlation indices of the 10 MW test with the RUNZI® app at fast speeds was moderate to excellent (r = .588-.957). At a comfortable speed, the correlation was excellent for walking speed (r = 0.944), moderate for steps (r = 0.780) and stride length (r = 0.760), and poor for cadence (r = .424). Results showed significant correlations between TUG and spatio-temporal gait parameters at fast and comfortable speeds. There were no significant correlations or consistent associations between Tinetti and BBS and RUNZI®. The test-retest reliability was good to excellent for parameters measured with the RUNZI®.

SIGNIFICANCE

Our findings highlight specific opportunities for a free smartphone-based spatio-temporal gait analysis to serve as a complement to conventional gait analysis methods in clinical practice with a moderate to excellent construct validity with the 10 MW test and good to excellent test-retest reliability in PD patients.

Active Muscle Trigger Points Are Associated with Pain and Related Disability in Patients with Plantar Heel Pain: A Case-Control Study

OBJECTIVE

Pain experienced by patients with plantar heel pain has been associated with fascia thickness. It is possible that referred muscle pain may also be related to symptoms experienced by these patients. Our aim was to systematically investigate if the referred pain elicited by trigger points in the leg and foot musculature reproduces the symptoms in individuals with plantar heel pain and to determine the association of trigger points (TrPs) with pain and related disability.

METHODS

A case-control study was conducted. Thirty-five individuals with unilateral chronic plantar heel pain and 35 matched comparable healthy controls participated. An assessor blinded to the subject's condition explored TrPs in the flexor hallucis brevis, adductor hallucis, quadratus plantae, and internal gastrocnemius. Pain and related disability were assessed with a numerical pain rating scale (0-10), the Foot Function Index, and the Foot Health Status Questionnaire.

RESULTS

The number of TrPs for each patient with plantar heel pain was 4 ± 3 (2.5 ± 2 active TrPs, 1.5 ± 1.8 latent TrPs). Healthy controls only had latent TrPs (mean = 1 ± 1). Active TrPs in the quadratus plantae (N = 20, 62.5%), and flexor hallucis brevis (N = 19, 59%) were the most prevalent in patients with plantar heel pain. A greater number of active, but not latent, TrPs was associated with higher foot pain variables (0.413 < rs < 0.561, P < 0.01), higher impact of foot pain (0.350 < rs < 0.473, P < 0.05) and worse related disability (-0.447 < rs < -0.35456, P < 0.05).

CONCLUSIONS

The referred pain elicited by active TrPs in the foot muscles reproduced the symptoms in patients with plantar heel pain. A greater number of active TrPs was associated with higher pain and related disability in patients with plantar heel pain.

Effects of Cervico-Mandibular Manual Therapy in Patients with Temporomandibular Pain Disorders and Associated Somatic Tinnitus: A Randomized Clinical Trial

Objective

This randomized clinical trial investigated the effects of adding cervico-mandibular manual therapies into an exercise and educational program on clinical outcomes in individuals with tinnitus associated with temporomandibular disorders (TMDs).

Methods

Sixty-one patients with tinnitus attributed to TMD were randomized into the physiotherapy and manual therapy group or physiotherapy alone group. All patients received six sessions of physiotherapy treatment including cranio-cervical and temporomandibular joint (TMJ) exercises, self-massage, and patient education for a period of one month. Patients allocated to the manual therapy group also received cervico-mandibular manual therapies targeting the TMJ and cervical and masticatory muscles. Primary outcomes included TMD pain intensity and tinnitus severity. Secondary outcomes included tinnitus-related handicap (Tinnitus Handicap Inventory [THI]), TMD-related disability (Craniofacial Pain and Disability Inventory [CF-PDI]), self-rated quality of life (12-item Short Form Health Survey [SF-12]), depressive symptoms (Beck Depression Inventory [BDI-II]), pressure pain thresholds (PPTs), and mandibular range of motion. Patients were assessed at baseline, one week, three months, and six months after intervention by a blinded assessor.

Results

The adjusted analyses showed better outcomes (all, P &lt; 0.001) in the exercise/education plus manual therapy group (large effect sizes) for TMD pain (η 2 P = 0.153), tinnitus severity (η 2 P = 0.233), THI (η 2 P = 0.501), CF-PDI (η 2 P = 0.395), BDI-II (η 2 P = 0.194), PPTs (0.363 &lt; η 2 P &lt; 0.415), and range of motion (η 2 P = 0.350), but similar changes for the SF-12 (P = 0.622, η 2 P = 0.01) as the exercise/education alone group.

Conclusions

This clinical trial found that application of cervico-mandibular manual therapies in combination with exercise and education resulted in better outcomes than application of exercise/education alone in individuals with tinnitus attributed to TMD.

Impact of social and occupational factors over job control

Background:

Psychosocial risk factors, among which job control has proved to be a key dimension, can have a negative impact on the health of workers. Various research projects have found a relationship between low levels of free time at work and stress and job satisfaction indicators.

Objectives:

to assess to what extent certain social and employment variables influence “job control”.

Methods:

A descriptive study was carried out on a sample of workers to analyse the influence of certain socio-demographic and work-related variables on job control, by means of an assessment survey on psychosocial risk and the general state of workers’ health. The tools used in this study were the COPSOQ-ISTAS 21 version 1.5 psychosocial risk assessment questionnaire and a specific survey on the perceived state of health.

Results:

Three hundred fourteen workers were asked to participate in the study. One hundred and ninety workers completed the questionnaire and were finally included. For the “job control” variable, 47.4% of workers described their situation as good. The results show that workers with a higher educational level (+78%), who have seniority in the job, have a good understanding of their situation at work (+15%), and are employed as white collars (34%), are more likely to show high job control and, therefore, could be less at risk from psychosocial factors.

Conclusions:

There are two parameters influencing “job control”: social factors concerning educational level, and work situation factors, including seniority and being a white collar worker.

The Dynamic Baropodometric Profile of Children with Idiopathic Toe-Walking A Cross-Sectional Study

BACKGROUND

Idiopathic toe-walking (ITW) gait may present in children older than 3 years and in the absence of a medical condition known to cause or be associated with toe-walking gait. It is unknown how this gait type changes pressure distribution in the growing foot. We sought to determine whether children with ITW gait exhibit different plantar pressures and temporal gait features than typically developing children.

METHODS

Children aged 3 to 6 years were recruited who had either a typical heel-toe gait pattern or a diagnosis of ITW. The ITW diagnosis was reported by the parent/caregiver and confirmed through history and physical examination. Temporal gait measures, peak pressures, and impulse percentages were measured. A minimum of ten unshod footprints were collected. Data were compared with unpaired t tests.

RESULTS

The study included 40 children with typical gait and 56 with ITW gait. The ITW group displayed lower peak pressures at the hallux, midfoot, and hindfoot ( P < .05) and higher and lower pressure impulse percentages at the forefoot ( P < .001) and hindfoot ( P < .001), respectively. The ITW group spent a higher percentage of contact time at all areas of the forefoot and less at the midfoot and rearfoot ( P < .05). There were no significant differences in total step duration and foot progression angle between groups ( P > .05).

CONCLUSIONS

There were differences in pressure distributions between groups. Understanding these differences may help us better understand the compensations or potential long-term impact that ITW gait may have on a young child's foot. Podiatric physicians may also consider the use of this equipment in the clinical setting to measure outcomes after treatment for ITW.

Widespread Pressure Pain Hypersensitivity in Musculoskeletal and Nerve Trunk Areas as a Sign of Altered Nociceptive Processing in Unilateral Plantar Heel Pain

Our aim was to investigate the differences in pressure sensitivity over musculoskeletal and nerve symptomatic and distant areas between individuals with plantar heel pain and healthy subjects and to determine the relationship between sensitivity to pressure pain, foot pain, and fascia thickness. Thirty-five patients with unilateral chronic plantar heel pain and 35 matched healthy controls participated. Pressure pain thresholds (PPTs) were assessed bilaterally over several nerve trunks (median, radial, ulnar, common peroneal, tibial, and sural nerve trunks) and musculoskeletal structures (calcaneus, medial gastrocnemius, tibialis anterior, and second metacarpal) by an assessor blinded to the subject's condition. Pain was assessed with a numerical pain rating scale (0-10), impact of foot pain was assessed with the Foot Function Index, and plantar fascia thickness was measured via ultrasound imaging. Analysis of covariance revealed lower widespread and bilateral PPTs over both nerve trunks and musculoskeletal structures in individuals with plantar heel pain (P < .001). Female patients showed lower PPT than male patients in almost all points (P < .001). PPT over the peripheral nerve trunks of the lower extremity were significantly associated with the intensity of pain at first step in the morning and with the foot function disability scale of the Foot Function Index (P < .05). This study found widespread pressure pain hypersensitivity over both nerve trunks and musculoskeletal structures in individuals with unilateral chronic plantar heel pain, suggesting the presence of a central altered central nociceptive pain processing. Pressure hypersensitivity over nerve trunks on the lower extremity was associated with higher pain intensity and related disability. PERSPECTIVES: This study found widespread pressure hypersensitivity over both nerve trunks and musculoskeletal structures in individuals with unilateral chronic plantar heel pain, as a manifestation of a centrally altered central nociceptive pain processing.

Spanish translation and validation of the Scale for Contraversive Pushing to measure pusher behaviour

INTRODUCTION

The aim of this study was to develop and validate a Spanish-language version of the Scale for Contraversive Pushing, used to diagnose and measure pusher behaviour in stroke patients.

METHODS

Translation-back translation was used to create the Spanish-language Scale for Contraversive Pushing; we subsequently evaluated its validity and reliability by administering it to a sample of patients. We also analysed its sensitivity to change in patients identified as pushers who received neurological physiotherapy.

RESULTS

Experts indicated that the content of the scale was valid. Internal consistency was very good (Cronbach's alpha of 0.94). The intraclass correlation coefficient showed high intra- and interobserver reliability (0.999 and 0.994, respectively). The Kappa and weighted Kappa coefficients were used to measure the reliability of each item; the majority obtained values above 0.9. Lastly, the differences between baseline and final evaluations of pushers were significant (paired sample t test), showing that the scale is sensitive to changes obtained through physical therapy.

CONCLUSIONS

The Spanish-language version of the Scale for Contraversive Pushing is valid and reliable for measuring pusher behaviour in stroke patients. In addition, it is able to evaluate the ongoing changes in patients who have received physical therapy.

Ultrasound Evaluation of the Abdominal Wall and Lumbar Multifidus Muscles in Participants Who Practice Pilates: A 1-year Follow-up Case Series

OBJECTIVE

The purpose of this study was to describe ultrasound (US) changes in muscle thickness produced during automatic activation of the transversus abdominis (TrAb), internal oblique (IO), external oblique (EO), and rectus abdominis (RA), as well as the cross-sectional area (CSA) of the lumbar multifidus (LM), after 1 year of Pilates practice.

METHODS

A 1-year follow-up case series study with a convenience sample of 17 participants was performed. Indeed, TrAb, IO, EO, and RA thickness, as well as LM CSA changes during automatic tests were measured by US scanning before and after 1 year of Pilates practice twice per week. Furthermore, quality of life changes using the 36-Item Short Form Health Survey and US measurement comparisons of participants who practiced exercises other than Pilates were described.

RESULTS

Statistically significant changes were observed for the RA muscle thickness reduction during the active straight leg raise test (P = .007). Participants who practiced other exercises presented a larger LM CSA and IO thickness, which was statistically significant (P < .05). Statistically significant changes were not observed for the domains of the analyzed 36-Item Short Form Health Survey (P > .05). A direct moderate correlation was observed (r = 0.562, P = .019) between the TrAb thickness before and after a 1-year follow-up.

CONCLUSIONS

Long-term Pilates practice may reduce the RA thickness automatic activation during active straight leg raise. Furthermore, LM CSA and IO thickness increases were observed in participants who practice other exercise types in conjunction with Pilates. Despite a moderate positive correlation observed for TrAb thickness, the quality of life did not seem to be modified after long-term Pilates practice.

Six weeks of multistation program on the knee proprioception and performance of futsal players

BACKGROUND

Proprioception and vertical jump are important parameters in the performance and prevention of injuries in futsal. However, very few studies have analyzed the role of multistation exercises to improve these variables. The purpose of this study was to assess the effects of a six-week multistation exercise program on knee joint position sense (JPS) and countermovement jump (CMJ) of futsal players.

METHODS

Thirty-four male futsal players randomly classified into experimental (N.=17) or control group (N.=17). The experimental group included a multistation exercise protocol to their training routines (2 times/week - 6 weeks); the control group continued their training routines. All the players completed similar training routines outside of the multistation exercises. Before (baseline), just after the intervention (Post6Wk) and four weeks later (Post10Wk), CMJ and knee JPS (absolute, relative and variable angular error: AAE, RAE and VAE, respectively) were evaluated.

RESULTS

ANOVA showed that the experimental group significantly decreased VAE at Post10Wk compared to baseline, suggestive of greater proprioceptive precision, while the control group significantly increased AAE, RAE and VAE at Post10Wk compared to baseline. The experimental group exhibited lower and thus, better AAE and VAE than the control group at Post10Wk, although no significant differences were found at Post6Wk. No significant differences was found in the CMJ.

CONCLUSIONS

A six weeks of multistation program may help improve proprioceptive precision of futsal players, even one month after finishing the 6-wk multistation training program. However, this is not long enough to improve proprioceptive acuity and maximum vertical jump. Therefore, the meaningful of these results in term of performance are unclear.

Role of upper cervical spine in temporomandibular disorders

BACKGROUND

Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial.

OBJECTIVE

To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD.

METHODS

Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms. Two X-ray examinations were performed in all the women: a lateral one and a frontal one with mouth open to assess the C1-C0 distance and the craniocervical angle.

RESULTS

ANOVA showed that the TMD and control women had similar C1-C0 distances and craniocervical angles (p> 0.05). Pearson correlation did not indicate any relationship between the craniocervical position and the symptomatology of TMD (r=- 0.070).

CONCLUSIONS

TMD symptomatology is unrelated to alterations in craniocervical position (C0-C1 distance and craniocervical angle). Women with and without TMD showed a similar prevalence of alteration in the craniocervical position.

A neurocognitive approach for recovering upper extremity movement following subacute stroke: a randomized controlled pilot study

[Purpose] This study aims to describe a protocol based on neurocognitive therapeutic exercises and determine its feasibility and usefulness for upper extremity functionality when compared with a conventional protocol. [Subjects and Methods] Eight subacute stroke patients were randomly assigned to a conventional (control group) or neurocognitive (experimental group) treatment protocol. Both lasted 30 minutes, 3 times a week for 10 weeks and assessments were blinded. Outcome measures included: Motor Evaluation Scale for Upper Extremity in Stroke Patients, Motricity Index, Revised Nottingham Sensory Assessment and Kinesthetic and Visual Imagery Questionnaire. Descriptive measures and nonparametric statistical tests were used for analysis. [Results] The results indicate a more favorable clinical progression in the neurocognitive group regarding upper extremity functional capacity with achievement of the minimal detectable change. The functionality results are related with improvements on muscle strength and sensory discrimination (tactile and kinesthetic). [Conclusion] Despite not showing significant group differences between pre and post-treatment, the neurocognitive approach could be a safe and useful strategy for recovering upper extremity movement following stroke, especially regarding affected hands, with better and longer lasting results. Although this work shows this protocol's feasibility with the panel of scales proposed, larger studies are required to demonstrate its effectiveness.

Reliability and minimal detectable change of three functional tests: forward-lunge, step-up-over and sit-to-stand

[Purpose] To examine the intrasession and intersession reliability and the absolute reliability of three functional dynamic tests—forward-lunge, step-up-over and sit-to-stand tests—using computerized dynamic posturography. [Subjects and Methods] An intra-test and test-retest, repeated measure study was designed. Forty-five healthy subjects twice carried out the forward-lunge test, step-up-over test, and sit-to-stand test on two days, one week apart. The intrasession and intersession reliabilities as judged by the intraclass correlation coefficient (ICC) and the minimal detectable change of the three functional tests were calculated. [Results] Excellent to very good intrasession reliability of the forward-lunge test (ICC range of 0.9–0.8) was found. Very good to good intrasession reliability of the step-up-over test (ICC range of 0.9–0.5) was found and very good intrasession reliability of the sit-to-stand test (ICC range of 0.8–0.7) was found. The minimal detectable change at the 95% confidence level of most of the measures was lower than 30%. [Conclusion] The forward-lunge, step-up-over and sit-to-stand tests are reliable measurement tools.

Neurodevelopment in preschool idiopathic toe-walkers

INTRODUCTION

Idiopathic toe walking, a differential diagnosis for neurological and orthopaedic disorders, has been associated with neurodevelopmental alterations. Neurodevelopmental assessment at early ages using specific tests may improve management and follow-up of these patients. The aim of our study is to analyse the neurodevelopmental characteristics of preschool idiopathic toe-walkers (ITW) by comparing them to a control group.

METHOD

Our descriptive cross-sectional study compared possible risk factors, neurodevelopmental characteristics, and scores on the Child Neuropsychological Maturity Questionnaire (CUMANIN) between a group of 56 ITWs aged 3 to 6 and a control group including 40 children.

RESULTS

The proportion of males was significantly higher in the ITW group (P=.008). The percentage of patients with a family history (P=.000) and biological risk factors during the perinatal period (P=.032) was also higher in this group. According to the parents' reports, motor coordination in ITWs was significantly poorer (59%; P=.009). ITWs scored significantly lower on CUMANIN subscales of psychomotricity (=0,001) and memory (P=.001), as well as in verbal development (P=.000), non-verbal development (P=.026), and overall development (P=.004). Foot preference was less marked in the ITW group (P=.047).

CONCLUSIONS

The neurodevelopmental characteristics of our sample suggest that idiopathic toe walking is a marker of neurodevelopmental impairment. However, further studies are necessary to confirm these findings.

Smoking Among Spanish Workers After Smoking Regulation

The aim of this study was to determine the prevalence of smoking among Spanish workers after a new smoking regulation became law. The researchers conducted a retrospective study with a worker sample. Information was collected via health examinations of 185 adults with a mean age of 35.93 ± 9.13 for men and 36.16 ± 9.52 for women who agreed to participate in the study in 2010, 2011, and 2012. The percentages of occasional smokers, light smokers, moderate smokers, and heavy smokers were compared by year for men and women. In 2010, 18% of women smokers were occasional, 45% light, 27% moderate, and 10% heavy smokers. Twenty-two percent of male smokers were occasional, 16% light, 28% moderate, and 34% heavy smokers. In 2011, 12% of ex-smokers were women and 14% were men. In 2012, 30% of ex-smokers were women and 22% were men. In conclusion, the percentage of ex-smokers has increased in this sample after the anti-smoking law was enacted.
