Comparison of 7.0-T T₂*-magnetic resonance imaging of cerebral bleeds in post-mortem brain sections of Alzheimer patients with their neuropathological correlates

BACKGROUND

In view of the increasing recognition of cerebral microbleeds (MCBs) with MRI, there is a need to validate their detection in post-mortem brains in patients with cerebrovascular diseases and dementia.

MATERIALS AND METHODS

Out of 20 post-mortem brains of patients with Alzheimer dementia and with different cerebrovascular lesions, 45 large sections of the cerebral hemispheres, brainstem and cerebellum were submitted to a 7.0-T T₂*-weighted MRI, and afterwards compared to the histological detection of haematomas, MCBs and mini-bleeds (MNBs).

RESULTS

The sensitivity, specificity, predictive positive value and predictive negative value of the T₂* imaging to detect MCBs and MNBs were excellent for those in the cortico-subcortical regions. There was a significant overestimation of MNBs in the striatum due to iron deposits unrelated to old haemorrhages. Also in the deep white matter, 42% of MNBs were not detected, while 31% of T₂* hyposignals were not due to MNBs but to vessels filled with post-mortem thrombi.

CONCLUSIONS

When evaluating the 'bleeding load' with 7.0-T T₂*-weighted MRI in post-mortem brain sections of patients with dementia and vascular risk factors, only quantification of small cerebral bleeds in the cortico-subcortical regions is reliable.

Iron deposits in post-mortem brains of patients with neurodegenerative and cerebrovascular diseases: a semi-quantitative 7.0 T magnetic resonance imaging study

BACKGROUND AND PURPOSE

Accumulation of iron (Fe) is often detected in brains of people suffering from neurodegenerative diseases. However, no studies have compared the Fe load between these disease entities. The present study investigates by T2*-weighted gradient-echo 7.0 T magnetic resonance imaging (MRI) the Fe content in post-mortem brains with different neurodegenerative and cerebrovascular diseases.

METHODS

One hundred and fifty-two post-mortem brains, composed of 46 with Alzheimer's disease (AD), 37 with frontotemporal lobar degeneration (FTLD), 11 with amyotrophic lateral sclerosis, 13 with Lewy body disease, 14 with progressive supranuclear palsy, 16 with vascular dementia (VaD) and 15 controls without a brain disease, were examined. The Fe load was determined semi-quantitatively on T2*-weighted MRI serial brain sections in the claustrum, caudate nucleus, putamen, globus pallidus, thalamus, subthalamic nucleus, hippocampus, mamillary body, lateral geniculate body, red nucleus, substantia nigra and dentate nucleus. The disease diagnosis was made on subsequent neuropathological examination.

RESULTS

The Fe load was significantly increased in the claustrum, caudate nucleus and putamen of FTLD brains and to a lesser degree in the globus pallidus, thalamus and subthalamic nucleus. In the other neurodegenerative diseases no Fe accumulation was observed, except for a mild increase in the caudate nucleus of AD brains. In VaD brains no Fe increase was detected.

CONCLUSIONS

Only FTLD displays a significant Fe load, suggesting that impaired Fe homeostasis plays an important role in the pathogenesis of this heterogeneous disease entity.

"Patient participation" and related concepts: A scoping review on their dimensional composition

OBJECTIVES

Several concepts on collaboration between patients and healthcare systems have emerged in the literature but there is little consensus on their meanings and differences. In this study, "patient participation" and related concepts were studied by focusing on the dimensions that compose them. This review follows two objectives: (1) to produce a detailed and comprehensive overview of the "patient participation" dimensions; (2) to identify differences and similarities between the related concepts.

METHODS

A scoping review was performed to synthesize knowledge into a conceptual framework. An electronic protocol driven search was conducted in two bibliographic databases and a thematic analysis was used to analyse the data.

RESULTS

The search process returned 39 articles after exclusion for full data extraction and analysis. Through the thematic analysis, the dimensions, influencing factors and expected outcomes of "patient participation" were determined. Finally, differences between the included concepts were identified.

CONCLUSION

This global vision of "patient participation" allows us to go beyond the distinctions between the existing concepts and reveals their common goal to include the patient in the healthcare system.

PRACTICE IMPLICATIONS

This scoping review provides useful information to propose a conceptual model of "patient participation", which could impact clinical practice and medical training programs.

Librarians in Evidence-Based Medicine Curricula: A Qualitative Study of Librarian Roles, Training, and Desires for Future Development

This study aims to describe librarians' roles in evidence-based medicine (EBM) from the librarian perspective, identify how librarians are trained to teach, and highlight preferences for professional development. A multiinstitution qualitative study was conducted. Nine medical librarians identified by their faculty as integrated into EBM training were interviewed. Participants' descriptions indicated that they were active in curriculum development, deployment (including teaching activities), and assessment to support EBM. Participants identified direct experience and workshop participation as primary methods of learning to teach. Participants desired continuing development as teachers and requested opportunities for in-person workshops, shadowing physicians, and online training.

Topography of Cortical Microbleeds in Alzheimer's Disease with and without Cerebral Amyloid Angiopathy: A Post-Mortem 7.0-Tesla MRI Study

Cortical microbleeds (CMBs) detected on T2*-weighted gradient-echo (GRE) magnetic resonance imaging (MRI) are considered as a possible hallmark of cerebral amyloid angiopathy (CAA). The present post-mortem 7.0-tesla MRI study investigates whether topographic differences exist in Alzheimer's brains without (AD) and with CAA (AD-CAA). The distribution of CMBs in thirty-two post-mortem brains, consisting of 12 AD, 8 AD-CAA and 12 controls, was mutually compared on T2*-GRE MRI of six coronal sections of a cerebral hemisphere. The mean numbers of CMBs were determined in twenty-two different gyri. As a whole there was a trend of more CMBs on GRE MRI in the prefrontal section of the AD, the AD-CAA as well as of the control brains. Compared to controls AD brains had significantly more CMBs in the superior frontal, the inferior temporal, the rectus and the cinguli gyrus, and in the insular cortex. In AD-CAA brains CMBs were increased in all gyri with exception of the medial parietal gyrus and the hippocampus. AD-CAA brains showed a highly significant increase of CMBs in the inferior parietal gyrus (p value: 0.001) and a significant increase in the precuneus and the cuneus (p value: 0.01) compared to the AD brains. The differences in topographic distribution of CMBs between AD and AD-CAA brains should be further investigated on MRI in clinically suspected patients.

Effects of Noise and a Speaker's Impaired Voice Quality on Spoken Language Processing in School-Aged Children: A Systematic Review and Meta-Analysis

PURPOSE

Background noise and voice problems among teachers can degrade listening conditions in classrooms. The aim of this literature review is to understand how these acoustic degradations affect spoken language processing in 6- to 18-year-old children.

METHOD

In a narrative report and meta-analysis, we systematically review studies that examined the effects of noise and/or impaired voice on children's response accuracy and response time (RT) in listening tasks. We propose the Speech Processing under Acoustic DEgradations (SPADE) framework to classify relevant findings according to three processing dimensions-speech perception, listening comprehension, and auditory working memory-and highlight potential moderators.

RESULTS

Thirty-one studies are included in this systematic review. Our meta-analysis shows that noise can impede children's accuracy in listening tasks across all processing dimensions (Cohen's d between -0.67 and -2.65, depending on signal-to-noise ratio) and that impaired voice lowers children's accuracy in listening comprehension tasks (d = -0.35). A handful of studies assessed RT, but results are inconclusive. The impact of noise and impaired voice can be moderated by listener, task, environmental, and exposure factors. The interaction between noise and impaired voice remains underinvestigated.

CONCLUSIONS

Overall, this review suggests that children have more trouble perceiving speech, processing verbal messages, and recalling verbal information when listening to speech in noise or to a speaker with dysphonia. Impoverished speech input could impede pupils' motivation and academic performance at school.

Current and future directions in Belgian medical and health sciences librarianship: a user-tailored approach

This article is part of a new series in this regular feature. The series intend to serve as a road map by sharing expertise and drawing together trends that are relevant to both health science librarians and health informatics professionals. The present article is a collaboration of six medical and health sciences libraries in Belgium and the Flemish library and archive association (VVBAD, n.d., https://www.vvbad.be/). It aims to elucidate the extended, user-tailored approach provided by medical and health sciences libraries in Belgium motivated by the recent changes in user expectations and behaviour.

Information behaviour of French-speaking speech-language therapists in Belgium: results of a questionnaire survey

BACKGROUND

Speech-language therapists (SLTs) are encouraged to implement evidence-based practice (EBP). Nevertheless, EBP use by practitioners can be questioned.

OBJECTIVES

The objective of this study was to explore Belgian French-speaking SLTs' information behaviour and their awareness of EBP. The collected data allow one to determine how far they have embraced this approach.

METHODS

The two Belgian French-speaking SLT professional associations promoted an online questionnaire survey by email. Additionally, clinical supervisors of students were asked to participate. In March 2012, 2068 emails were sent.

RESULTS

The participation rate was at least 20% (n = 415). The reported information needs mainly concerned treatment or diagnosis. Most of the time, to attempt to fulfil their information needs, SLTs relied on their own resources (personal experience and libraries) and on colleagues in the workplace. When they searched on the Internet, they preferred to use a general search engine rather than a specialised bibliographic database. Barriers to obtaining scientific information are highlighted. Only 12% of the respondents had already heard about EBP.

CONCLUSION

This study provides the first overview of the information behaviour of SLTs working in the French community of Belgium. Several recommendations are suggested for SLTs and librarians.

Empathy in patient-clinician interactions when using telecommunication: A rapid review of the evidence

Objectives

The COVID-19 pandemic accelerated the replacement of many face-to-face healthcare consultations with telephone consultations. Little is known about the extent to which empathy can be expressed in telephone consultations. Our objective is to review evidence related to empathy in telephone consultations including clinical outcomes, and patient/practitioner experiences.

Methods

Searches of Medline/Ovid and PsycINFO/Ovid were undertaken. Titles and abstract screening, data extraction, and risk of bias were undertaken by two reviewers. Discrepancies were resolved in discussion with additional reviewers. Included studies were specific to tele-communications with empirical data on empathy related to patient outcomes/views, published (in English), 2010–2021. Studies that did not mention empathy explicitly were excluded.

Results

Our search yielded 740 individual records and 8 studies (527 patients, 20 practitioners) met inclusion criteria: Some barriers to expression of empathy were noted, but no major obstacles were reported. However, data was sparse and most studies had a high risk of bias.

Conclusion

Empathy in telephone consultations is possible, (though the loss of non-verbal cues and touch can present barriers) however the research does not yet identify how.

Innovation

It is possible to establish and display empathy in telephone consultations, but future research needs to identify how this can be optimized.

Exercise therapy including the cervical extensor muscles in individuals with neck pain: A systematic review

OBJECTIVE

To review the use (dosage parameters and combination with other therapeutic interventions) of cervical extensor muscle exercises and their effect on pain, disability (primary outcomes), range of motion, endurance and strength (secondary outcomes) in people with neck pain.

DATA SOURCES

An extensive literature search was conducted through MEDLINE (Ovid), Scopus (Elsevier) and Physiotherapy Evidence Database (PEDro) up to May 2023. The reference lists of all included studies and relevant reviews were screened for additional studies.

REVIEW METHODS

Randomised controlled trials reporting the use of cervical extensor muscle exercises (alone or combined) applied to adults with idiopathic or traumatic neck pain were included. Study selection, data extraction and critical appraisal (PEDro assessment scale) were performed by two blinded reviewers. Data extraction included dosage parameters, other modalities combined with these exercises and outcomes.

RESULTS

Thirty-five randomised controlled trails (eight of which were complementary analyses) with 2409 participants fulfilled the inclusion criteria. Twenty-six were of moderate to high quality. In most studies, cervical extensor muscle exercises were combined with various other therapeutic modalities and applied at different dosages. Only two studies (one high and one low quality) specifically assessed their effectiveness. The high-quality study showed significant improvements in neck pain and disability, pressure point threshold and neck mobility after both low load and high load training for 6 weeks.

CONCLUSION

The results suggest cervical extensor muscle exercises may reduce neck pain and disability; however firm conclusions cannot be drawn because of the few studies that addressed this question and the heterogeneity of the dosage parameters.

Clinical Value and Reliability of Quantitative Assessments of Lumbosacral Nerve Root Using Diffusion Tensor and Diffusion Weighted MR Imaging: A Systematic Review

BACKGROUND

Lumbosacral radicular pain diagnosis remains challenging. Diffusion tensor imaging (DTI) and diffusion weighted imaging (DWI) have potential to quantitatively evaluate symptomatic nerve root, which may facilitate diagnosis.

PURPOSE

To determine the ability of DTI and DWI metrics, namely fractional anisotropy (FA) and apparent diffusion coefficient (ADC), to discriminate between healthy and symptomatic lumbosacral nerve roots, to evaluate the association between FA and ADC values and patient symptoms, and to determine FA and ADC reliability.

STUDY TYPE

Systematic review.

SUBJECTS

Eight hundred twelve patients with radicular pain with or without radiculopathy caused by musculoskeletal-related compression or inflammation of a single, unilateral lumbosacral nerve root and 244 healthy controls from 29 studies.

FIELD STRENGTH/SEQUENCE

Diffusion weighted echo planar imaging sequence at 1.5 T or 3 T.

ASSESSMENT

An extensive systematic review of the literature was conducted in Embase, Scopus, and Medline databases. FA and ADC values in symptomatic and contralateral lumbosacral nerve roots were extracted and summarized, together with intra- and inter-rater agreements. Where available, associations between DWI or DTI parameters and patient symptoms or symptom duration were extracted.

STATISTICAL TESTS

The main results of the included studies are summarized. No additional statistical analyses were performed.

RESULTS

The DTI studies systematically found significant differences in FA values between the symptomatic and contralateral lumbosacral nerve root of patients suffering from radicular pain with or without radiculopathy. In contrast, identification of the symptomatic nerve root with ADC values was inconsistent for both DTI and DWI studies. FA values were moderately to strongly correlated with several symptoms (eg, disability, nerve dysfunction, and symptom duration). The inter- and intra-rater reliability of DTI parameters were moderate to excellent. The methodological quality of included studies was very heterogeneous.

DATA CONCLUSION

This systematic review showed that DTI was a reliable and discriminative imaging technique for the assessment of symptomatic lumbosacral nerve root, which more consistently identified the symptomatic nerve root than DWI. Further studies of high quality are needed to confirm these results.

Cervical extensor muscle activity during neck tasks in individuals with and without neck pain: A systematic review

BACKGROUND

In the context of neck pain, neck muscle activity adapts through diverse regional coordination modifications during tasks. Although patterns of cervical flexor muscle impairment are well-documented, patterns in the cervical extensor muscles are less clear, hindering assessment and treatment. Despite studies revealing adaptations in the cervical extensor muscles, outcome measure heterogeneity complicates interpretation, particularly between superficial and deep muscles. To address this, we conducted a systematic review comparing neck extensor muscle activity between symptomatic and asymptomatic groups during tasks, aiming to inform clinical practice.

OBJECTIVES

To compare the cervical extensor muscle activity during neck tasks between symptomatic and asymptomatic groups, using complementary examination tools.

METHODS

Up to January 2024, experimental studies assessing cervical extensor muscle activity during neck tasks in adults with idiopathic or traumatic neck pain, or cervicogenic headache compared to healthy controls were included. Study selection involved 2 blinded reviewers. Electronic databases (Medline, Scopus, and Embase), reference lists, and relevant reviews were screened. Data extraction focused on the results of the between-group motor activity comparisons. Critical appraisal used the JBI appraisal checklist for analytical cross-sectional studies.

RESULTS

Twenty-three studies met the inclusion criteria, involving 932 participants and reporting 170 comparative assessments of 8 muscle groups, encompassing 4 main motor activity outcomes: recruitment, timing, fatigue, and directional activation. Significant differences were noted for motor recruitment in 51 % of comparisons, for timing in 35 %, and fatigue in 33 %, with consistent differences in directional activation. Impaired activity in individuals with neck pain compared to those without was found in 47 % of comparisons for superficial muscles and 65 % for deep muscles.

CONCLUSIONS

Motor activity adaptations during neck tasks appear to be unpredictable in individuals with neck pain, with a tendency for change in the deep cervical extensor muscles. Further high-quality studies are needed to confirm these findings, considering various contraction parameters, multiple muscle analyses, and several motor activity outcomes.

Interventions That Target or Affect Voice or Speech Production During Public Speaking: A Scoping Review

OBJECTIVES

Public speaking (PS) is frequently necessary in many professional, educational, and personal settings. Mastering this communication skill is particularly important in today's society. Training techniques for PS have been described in the literature. Given that PS anxiety affects performance, especially voice characteristics and speech fluency, the purpose of this scoping review is to examine, map, and narratively summarize the available evidence on PS interventions that target or affect voice or speech.

METHODS

An extensive literature search was conducted in three bibliographic databases: Medline ALL/Ovid, PsycINFO/Ovid, and Eric/Ovid. Of the 850 studies identified, 22 met the eligibility criteria, and one was added from the reference lists of the included studies.

RESULTS

A total of 23 studies were included. The interventions identified aim to improve speaking skills either by explicitly targeting the voice or speech (direct intervention, n = 15) or by targeting the cognitive, behavioral, psychological, or physical environment impacting the speaker's production (indirect intervention, n = 8).

CONCLUSIONS

This scoping review provides the first published methodological summary of the characteristics of existing PS interventions that target or affect voice and speech. Heterogeneous characteristics were observed. Further studies are needed to determine which interventions are most effective.

Patients' perceptions of the mechanisms underlying alcohol use problems after bariatric surgery: A qualitative systematic review

Alcohol-related problems increase after bariatric surgery. The objective of this review was to synthesize findings of qualitative studies on patients' perceptions of the mechanisms leading to problematic alcohol consumption after bariatric surgery. This review followed the Joanna Briggs Institute methodology for systematic review of qualitative evidence. A comprehensive search strategy was performed in MEDLINE, PsycInfo, Scopus and Google Scholar. Study selection, data extraction and critical appraisal of included studies were undertaken by two independent reviewers. Confidence in review findings was assessed using the ConQual approach. Four studies were included in this review and led to the development of four synthesized results: (1) persistence or reappearance of psychological problems after bariatric surgery; (2) using alcohol as a coping strategy, sometimes as a replacement for food; (3) changes in the physiological response to alcohol; and (4) importance of increased information about alcohol-related risks and long-term counselling. Confidence in the synthesized results ranged from moderate to low. The results indicated postoperative problematic alcohol consumption is a complex issue, involving psychological and physiological mechanisms. Several recommendations are formulated based on the results obtained. More qualitative and quantitative studies are needed to better understand this phenomenon given the few existing qualitative studies on this topic and some divergent results found between qualitative and previous quantitative research.

Implementations of sign- and goal-tracking behavior in humans: A scoping review

Animal research has identified two major phenotypes in the tendency to attribute incentive salience to a reward-associated cue. Individuals called "sign-trackers" (STs) preferentially approach the cue, assigning both predictive and incentive values to it. In contrast, individuals called "goal-trackers" (GTs) preferentially approach the location of the upcoming reward, assigning only a predictive value to the cue. The ST/GT model has been shown to be relevant to understanding addiction vulnerability and other pathological behaviors in animals. Therefore, recent studies tried to implement this animal model in the human population. This scoping review aimed to identify and map evidence of human sign- and goal-tracking. Studies that explicitly measured human sign- and goal-tracking or related phenomena (e.g., attentional bias induced by reward-related cues), using paradigms in line with the animal model, were eligible for this review. We searched for published, unpublished, and gray literature (PhD theses, posters, conference papers) through the following databases: MEDLINE, Scopus, PsycINFO, Embase, OSF, and Google Scholar. The JBI scoping review methodology was adopted. Screening and extraction were carried out by three reviewers, in pairs. A total of 48 studies were identified. These studies used various experimental paradigms and used the term "sign-tracking" inconsistently, sometimes implicitly or not at all. We conclude that the literature on human sign-tracking is very heterogeneous on many levels. Overall, evidence supports the existence of sign- and goal-tracking behaviors in humans, although further validated research is crucially needed.

Effet longitudinal d’une administration aiguë d’éthanol sur le GABA et le glutamate : une étude en spectroscopie par résonance magnétique in vivo chez le rat

Introduction

Les effets cliniques de l’intoxication alcoolique aiguë seraient liés à une modulation des systèmes de neurotransmission du GABA et du glutamate. Les caractéristiques longitudinales de cette modulation et l’impact de la dose d’éthanol absorbée restent mal connus. Nous avons voulu étudier in vivo les effets aigus de l’éthanol sur les niveaux de GABA et de glutamate du cortex préfrontal en spectroscopie par résonance magnétique (SRM).

Matériel et méthodes

Après une première acquisition de SRM (zone préfrontale), trois groupes de rats Wistar mâles (363 ± 27 g) ont reçu par voie intrapéritonéale (IP) :

– éthanol 1 g/kg (n = 6) ;

– éthanol 2 g/kg (n = 8) ;

– sérum physiologique (n = 5).

Des acquisitions répétées de SRM ont été réalisées jusque 300 minutes post-injection. Une cinétique de l’éthanolémie a également été réalisée dans des groupes similaires de rats Wistar. Après alcoolisation par voie IP, des prélèvements sanguins successifs ont été réalisés jusque 180 minutes pour le groupe 1 g/kg (n = 6) et 300 minutes pour le groupe 2 g/kg (n = 14). Pour la SRM, des analyses statistiques inter- et intragroupes ont été effectuées à l’aide d’un modèle linéaire mixte visant à étudier la variation des taux de GABA et glutamate.

Résultats

La cinétique de l’éthanolémie était superposable à celle de la cinétique cérébrale. En SRM, une diminution significative du GABA, de 11,4 % ± 3,8 % (p < 0,0059) dans le groupe 1 g/kg et du glutamate de 13,8 % ± 2,6 % dans le groupe 2 g/kg (p < 0,0001) ont été observées, sans modification significative dans les autres groupes. La variation du ratio GABA/glutamate s’est montrée différente entre les deux groupes éthanol avec une augmentation dans le groupe 2 g/kg et une diminution dans le groupe 1 g/kg (p < 0,01).

Conclusion

La dose d’éthanol détermine les variations des niveaux de GABA et de glutamate du cortex préfrontal, pouvant expliquer les différents effets cliniques induits par l’alcool selon la dose.

[OCEBM levels of evidence system]

The hierarchy of evidence from medical research is a key concept in evidence-based medicine (EBM). In 1998, the Oxford Centre for Evidence-Based Medicine published a levels table based on study designs. An updated and more user-friendly version, published in 2011, focuses on the issues of prevalence, diagnosis, prognosis, treatment and screening. This paper presents and discusses this approach.

Effects of nutritional counseling on physical performance and muscle strength in older adults: a systematic review protocol

OBJECTIVE

The objective of this review is to synthesize the effects of nutritional counseling compared with no intervention (maintaining lifestyle habits) or nutritional counseling in combination with other interventions (eg, nutritional supplementation, physical activity) on physical performance and muscle strength in older adults.

INTRODUCTION

Nutritional counseling, which is considered the first line of nutrition therapy, could play an important role in geriatric care programs by helping older adults understand the importance of nutrition and by promoting healthy, sustainable eating habits. However, the effects of nutritional counseling on physical function and muscle strength among older adults are not clear.

INCLUSION CRITERIA

This review will consider randomized controlled trials and non-randomized controlled trials. Participants aged 65 years or older, who have received nutritional counseling alone or in combination with another intervention (eg, nutritional supplementation, physical exercise) will be considered for inclusion. Comparators will include another intervention or no intervention, but physical performance (ie, gait, endurance, balance) or muscle strength must be measured.

METHODS

This systematic review will be conducted in accordance with the JBI methodology for systematic reviews of effectiveness. The databases to be searched will include MEDLINE (Ovid), Embase, CENTRAL (Ovid), CINAHL (EBSCOhost), and Scopus. Sources of unpublished studies and gray literature will include Google Scholar and protocol registers. Two independent reviewers will select relevant studies, critically appraise the studies, and extract data. Studies will be pooled in a statistical meta-analysis or presented in narrative format. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach will be used to grade the certainty of the evidence.

Effectiveness of manual techniques, exercise therapy, or combined treatments in the management of ankle sprains or chronic ankle instability in adult athletes: a systematic review protocol

OBJECTIVE

The objective of this review will be to synthesize the evidence on the effectiveness of manual techniques, exercise therapy, or combined treatments in the management of ankle sprains and chronic ankle instability in adult athletes.

INTRODUCTION

Acute ankle sprains and chronic ankle instability are common in athletes. These conditions can result in varying degrees of disability, including reduced athletic performance and time out of competition, which may have adverse psychological effects.

INCLUSION CRITERIA

The review will consider randomized controlled trials evaluating the effectiveness of manual techniques and/or exercise therapy for ankle sprain or chronic ankle instability in adult athletes. The comparators will include sham treatment, no treatment, and other conservative interventions. The outcomes of interest will be pain intensity, functional disability, ankle joint range of motion, ankle muscle strength, postural control, and subjective stability.

METHODS

The review will follow the JBI methodology for systematic reviews of effectiveness. Searches will be conducted to locate published and unpublished studies in the following sources: MEDLINE (Ovid), CENTRAL (Ovid), Embase, SPORTDiscus (EBSCOhost), Physiotherapy Evidence Database (PEDro), Google Scholar, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP). Two independent reviewers will select the study, critically appraise it, and extract data. Then, a narrative synthesis and, if appropriate, a meta-analysis will be performed. The certainty of findings will be determined using the GRADE approach.
