Meta-Analysis Review
BACKGROUND
Fear of falling (FOF) and increased gait variability are both independent markers of gait instability. There is a complex interplay between both entities. The purposes of this study were (1) to perform a qualitative analysis of all published studies on FOF-related changes in gait variability through a systematic review, and (2) to quantitatively synthesize FOF-related changes in gait variability.
METHODS
A systematic Medline literature search was conducted in May 2014 using the Medical Subject Heading (MeSH) terms "Fear" OR "fear of falling" combined with "Accidental Falls" AND "Gait" OR "Gait Apraxia" OR "Gait Ataxia" OR "Gait disorders, Neurologic" OR "Gait assessment" OR "Functional gait assessment" AND "Self efficacy" OR "Self confidence" AND "Aged" OR "Aged, 80 and over." Systematic review and fixed-effects meta-analysis using an inverse-variance method were performed.
RESULTS
Of the 2184 selected studies, 10 observational studies (including 5 cross-sectional studies, 4 prospective cohort studies, and 1 case-control study) met the selection criteria. All were of good quality. The number of participants ranged from 52 to 1307 older community-dwellers (26.2%-85.0% women). The meta-analysis was performed on 10 studies with a total of 999 cases and 4502 controls. In one study, the higher limits of the effect size's confidence interval (CI) were lower than zero. In the remaining studies, the higher limits of the CI were positive. The summary random effect size of 0.29 (95% CI 0.13-0.45) was significant albeit of small magnitude, and indicated that gait variability was overall 0.29 SD higher in FOF cases compared with controls.
CONCLUSIONS
Our findings show that FOF is associated with a statistically significant, albeit of small magnitude, increase in gait variability.

UNLABELLED
Dysphagia is described as a highly relevant comorbidity of Alzheimer's disease (AD). However, there is a scarcity of studies aiming at the characteristics and progression of dysphagia.
OBJECTIVE
The objective of this study was to identify the specific characteristics, progression, and prevalence of dysphagia in AD.
METHODS
Publications were searched in the PubMed (MEDLINE), EBSCO, ScienceDirect, and BASE databases. Critical appraisal and evidence-level analysis were conducted using the Joanna Briggs Institute and Effective Public Health Practice Project's (EPHPP) tools.
RESULTS
A total of 26 studies were reviewed. Symptoms begin in the early stage of AD, as oral phase impairments, and progress to pharyngeal symptoms and swallowing apraxia in the later stages of AD. Dysphagia progresses, as AD, along a , with severity depending on individual variability. There were no studies found on prevalence.
CONCLUSIONS
Dysphagia is a complex and important comorbidity in AD that impacts the quality of life. No recent publications on prevalence may imply that is not being coded as a potential cause for pneumonia deaths in AD.

Review
The objective was to assess effectiveness of apraxia treatments using a systematic review. In contrast to previous reviews, each study was rated as to its applicability to occupational therapy practice and its focus on occupational performance using the FAME rating system (defined by four categories: Feasibility, Appropriateness, Meaningfulness, Effectiveness). This systematic review included eight studies: four randomized controlled trials (level 1 evidence) and four pre-post designs (level 3 evidence). Three treatment approaches were reported: errorless learning with training of details; gesture training; and strategy training. FAME scores ranged from A to C. All studies reported significant treatment effects, but only one demonstrated an impact on observed occupational performance that transferred from clinic to home.

Review
A systematic review on production and comprehension of linguistic prosody in people with acquired language and communication disorders resulting from unilateral brain lesions.
BACKGROUND
Prosody serves central functions in language processing including linguistic functions (linguistic prosody), like structuring the speech signal. Impairments in production and comprehension of linguistic prosody have been described for persons with unilateral right (RHDP) or left hemisphere damage (LHDP). However, reported results differ with respect to the characteristics and severities of these impairments AIMS: We conducted a systematic literature review focusing on production and comprehension of linguistic prosody at the prosody-syntax interface (i.e., phrase or sentence level) in LHDP and RHDP.
METHODS & PROCEDURES
In a systematic literature search we included: (i) empirical studies with (ii) adult RHDP and/or LHDP (iii) investigating production and/or comprehension of linguistic prosody at the (iv) phrase or sentence level (v) reporting quantitative data on prosodic measures. We excluded overview papers; studies involving participants with dysarthria, apraxia of speech, foreign accent syndrome, psychiatric diseases, and/or neurodegenerative diseases; studies focusing primarily on emotional prosody; and on lexical stress / word level; studies of which no full text was available and/or that were published in a language other than English. We searched the databases BIOSIS, MEDLINE, EMBASE, PubMed, Web of Science, CINAHL, Cochrane Library, PSYNDEX, PsycINFO and speechBITE, last searched on January 13 2022.We found 2,631 studies without duplicates. We identified 43 studies which were included into our systematic review. For data extraction and synthesis of results, we grouped studies by (i) modality (production vs. comprehension), (ii) function (syntactic structure vs. information structure), and (iii) by experiment task. For production studies, outcome measures were defined as the productive use of the different prosodic cues (lengthening, pause, f0, amplitude). For comprehension studies, performance measures (accuracy and reaction times) were defined as outcome measures. In accordance with the PRISMA 2020 statement (Page et al., 2021), we conducted a quality check to assess study risk of bias. Our review was pre-registered with PROSPERO (CRD42019120308).
OUTCOMES & RESULTS
Of the 43 studies reviewed, 30 studies involved RHDP (n = 309), assessing production in 15 studies and focusing on comprehension of prosody in 16 studies (one study investigated production and comprehension). LHDP (n = 438) were included in 35 studies of which 15 studied production and 21 evaluated comprehension of prosody (one study investigated production and comprehension). Despite the heterogeneity of results in the studies reviewed, our synthesis of results suggests that both LHDP and RHDP show limitations, but no complete impairment, in their production and/or comprehension of linguistic prosody. Prosodic limitations are evident in different areas of processing linguistic prosody, like syntactic disambiguation or the distinction between sentence types. There is a tendency towards more severe limitations in LHDP as compared to RHDP.
CONCLUSIONS
We only included published studies into our review and did not perform an assessment of risk of reporting bias as well as systematic certainty assessments of the outcomes. Despite these limitations, we conclude that both groups show deficits in production and comprehension of linguistic prosody, but neither LHDP nor RHDP are completely impaired in their prosodic processing. This suggests that prosody is a relevant communicative resource for LHDP and RHDP worth being addressed in speech-language-therapy.

Meta-Analysis Review
BACKGROUND
Poor gait performance predicts risk of developing dementia. No structured critical evaluation has been conducted to study this association yet. The aim of this meta-analysis was to systematically examine the association of poor gait performance with incidence of dementia.
METHODS
An English and French Medline search was conducted in June 2015, with no limit of date, using the medical subject headings terms "Gait" OR "Gait Disorders, Neurologic" OR "Gait Apraxia" OR "Gait Ataxia" AND "Dementia" OR "Frontotemporal Dementia" OR "Dementia, Multi-Infarct" OR "Dementia, Vascular" OR "Alzheimer Disease" OR "Lewy Body Disease" OR "Frontotemporal Dementia With Motor Neuron Disease" (Supplementary Concept). Poor gait performance was defined by standardized tests of walking, and dementia was diagnosed according to international consensus criteria. Four etiologies of dementia were identified: any dementia, Alzheimer disease (AD), vascular dementia (VaD), and non-AD (ie, pooling VaD, mixed dementias, and other dementias). Fixed effects meta-analyses were performed on the estimates in order to generate summary values.
RESULTS
Of the 796 identified abstracts, 12 (1.5%) were included in this systematic review and meta-analysis. Poor gait performance predicted dementia [pooled hazard ratio (HR) combined with relative risk and odds ratio = 1.53 with P < .001 for any dementia, pooled HR = 1.79 with P < .001 for VaD, HR = 1.89 with P value < .001 for non-AD]. Findings were weaker for predicting AD (HR = 1.03 with P value = .004).
CONCLUSIONS
This meta-analysis provides evidence that poor gait performance predicts dementia. This association depends on the type of dementia; poor gait performance is a stronger predictor of non-AD dementias than AD.

Review
Non-invasive brain stimulation (NIBS) techniques are widely used in research settings to investigate brain mechanisms and increasingly being used for treatment purposes. The aim of this study was to systematically identify and review the current literature on NIBS studies of limb praxis and apraxia in healthy subjects and stroke patients with a scoping review using PRISMA-ScR guidelines. MEDLINE-PubMed, EMBASE and PsycINFO were searched. Inclusion criteria were English peer-reviewed studies focusing on the investigation of limb praxis/apraxia using repetitive transcranial magnetic stimulation (rTMS), or transcranial direct current stimulation (tDCS). Fourteen out of 139 records met the inclusion criteria, including thirteen studies with healthy subjects and one with stroke patients. The results of our systematic review suggest that in healthy subjects NIBS over left inferior parietal lobe (IPL) mainly interfered with gesture processing, by either affecting reaction times in judgment tasks or real gesturing. First promising results suggest that inhibitory continuous theta burst stimulation (cTBS) over right IPL may enhance gesturing in healthy subjects, explained by transcallosal facilitation of left IPL. In stroke patients, excitatory anodal tDCS over left IPL may improve limb apraxia. However, larger well powered and sham-controlled clinical trials are needed to expand on these proof-of-concept results, before NIBS could be a treatment option to improve limb apraxia in stroke patients.

American Journal of Speech-language... May 2023This systematic review aims to summarize and evaluate the available literature on speech and language therapy interventions for acquired apraxia of speech since 2012.
PURPOSE
This systematic review aims to summarize and evaluate the available literature on speech and language therapy interventions for acquired apraxia of speech since 2012.
METHOD
A systematic search in six electronic databases was performed from 2013 to 2020. The following primary outcomes were summarized: (a) improvement in targeted behaviors, (b) generalization, and (c) maintenance of outcomes. Moreover, studies were evaluated for the level of evidence and the clinical phase.
RESULTS
Of the 3,070 records identified, 27 studies were included in this review. The majority of the studies ( = 22) used articulatory kinematic approaches followed by intersystemic facilitation/reorganization treatments ( = 4) and other approaches ( = 1). According to the classes defined in (Gronseth et al., 2017), one was Class II, 10 were Class III, 10 were Class III-b (fulfill Class III criteria except for independence of assessors' criterion), and five were Class IV. In terms of clinical phase, one study classified as Phase III, 10 as Phase II, and 15 as Phase I.
CONCLUSIONS
Among the interventions for apraxia of speech, articulatory kinematic treatments have become prominent over the last 8 years. Focusing on self-administrated therapies, use of technology for therapy administration and development of treatments that focus on apraxia of speech and aphasia simultaneously were identified as new advancements in the apraxia of speech literature. The methodological quality, clinical phase, and level of evidence of the studies have improved within the past 8 years. Large-scale randomized controlled trials for articulatory kinematic approaches and future studies on other treatment approaches are warranted.

Apraxia is widely used to describe one of the more disabling deficits following left strokes. The role of rehabilitation in treating apraxic stroke patients remains unclear. This systematic review was conducted to study the impacts of various rehabilitation interventions on the limb apraxia post-stroke. PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, and Web of Science were searched for the experimental studies that investigated the effects of the rehabilitation interventions on apraxia in patients with stroke. The methodological quality was rated using the Physiotherapy Evidence Database scale (PEDro). Six studies met our inclusion criteria in this systematic review. Four were randomized controlled trials, pilot ( = 1), and case study ( = 1). The scores on the PEDro scale ranged from two to eight, with a median of seven. The results showed some evidence for the effects of strategy training and gesture training interventions on the cognitive functions, motor activities, and activities of daily livings outcomes poststroke. The preliminary findings showed that the effects of the strategy training and the gesture training on apraxia in patients with stroke are promising. Further randomized controlled trials with long-term follow-ups are strongly needed.

Review
Apraxia is a cognitive-motor planning disorder that expresses itself as an inability to perform purposeful and skilled movements in the absence of sensory or motor loss and hampers patients' ability to perform activities of daily living (ADL). ADL is a set of everyday tasks required for personal care and independent living, executed through a complex interaction between sensorimotor integration and motor learning. We have designed a 'Strategy training' program for apraxia patients by reviewing the existing clinical trial literature on the above-said topic per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Strategy training is an evidence-based standardized occupational therapy program to improve ADL in apractic patients by teaching them a variety of compensatory strategies to combat impairment and improve activity performance. Three basic steps of strategy training include: 1) initiation-development of an action plan, 2) execution-performance of the plan, and 3) control-assessment and result of action performed. The patient group suggested for strategy training comprises post-stroke (past 20 weeks) apraxia patients aged 40-90 years of both genders, highly motivated and fit to perform ADL. After preliminary assessment, 'strategy training' will be specifically executed through an exclusively visual feedback approach in which apraxia patients learn eight ADLs in 8 weeks (three sessions of 30 minutes/week for 8 weeks). They practice two ADLs for 15 minutes each in every session, thus a total of six sessions will be allocated to learn two ADLs simultaneously followed by the next set of ADLs. Strategy training for brushing teeth is described in detail to show how each step of this training program is implemented for a specific ADL. As this strategy training program is based on individual care, attention, and augmenting motivational aspects, it is expected to teach patients compensatory strategies to learn and perform ADL more smoothly, swiftly, and most importantly independently. The program is not aimed at treating clinical motor symptoms of apraxia per se but to help patients function more independently post apractic motor impairment.

Review
When working with individuals with little or no functional speech, clinicians often recommend that communication partners use the client's augmentative and alternative communication (AAC) device when speaking to the client. This is broadly known as "augmented input" and is thought to enhance the client's learning of language form and content. The purpose of this systematic review was to determine the effects of augmented input on communication outcomes in persons with developmental disabilities and persons with childhood apraxia of speech who use aided AAC. Nineteen studies met the inclusion criteria. Each included study was reviewed in terms of participant characteristics, terminology used, symbol format, augmented input characteristics, outcomes measured, effectiveness, and study quality. Results indicate that augmented input can improve single-word vocabulary skills and expression of multi-symbol utterances; however, comprehension beyond the single word level has not been explored. Additionally, it is difficult to form conclusions about the effect of augmented input on specific diagnostic populations. Directions for future research are posited.
