Abstract
This paper introduces the Special Issue of Neuropsychological Rehabilitation on Single Case Experimental Design (SCED) methodology. SCED studies have a long history of use in evaluating behavioural and psychological interventions, but in recent years there has been a resurgence of interest in SCED methodology, driven in part by the development of standards for conducting and reporting SCED studies. Although there is consensus on some aspects of SCED methodology, the question of how SCED data should be analysed remains unresolved. This Special Issues includes two papers discussing aspects of conducting SCED studies, five papers illustrating use of SCED methodology in clinical practice, and nine papers that present different methods of SCED data analysis. A final Discussion paper summarises points of agreement, highlights areas where further clarity is needed, and ends with a set of resources that will assist researchers conduct and analyse SCED studies.

Abstract
Vocal challenging behavior (VCB) forms a common problem in individuals with autistic disorder. Since VCB is associated with negative outcomes for the individual and his or her environment, it is important to know how to manage this type of CB. To evaluate the effectiveness of several psychosocial interventions applied to decrease VCB in individuals with autistic disorder, we conducted a meta-analysis of single-case experiments (SCEs). Fifty-two SCEs, including 74 participants, were combined using a multilevel meta-analysis. The overall treatment effect was large and statistically significant. However, the effect varied significantly over the included studies and participants. Examining this variance, evidence was found for a moderator effect of VCB type and intervention type, with, on average, the largest effects for interventions used to reduce VCB including stereotypical VCB and for interventions containing both antecedent and consequence components. Age, gender, primary treatment setting, publication year, and study quality did not significantly moderate the intervention effect.

Abstract
OBJECTIVE To examine the "clinical utility" of a new virtual rehabilitation tool in order to treat upper-limb motor deficit in cerebral palsy (CP) patient. METHODS Single-case experimental designs. Virtual reality intervention was performed in two left unilateral spastic CP adolescent patients. The virtual reality intervention was given for 60 minutes per session, two sessions a day, and 5 days a week over 2 weeks. RESULTS For each patient and for both hands, the number of blocks transported within one minute (box and block test scores) is increased. The nonoverlap of all pairs indices for the paretic hand were calculated as 0.95 for subject 1 and 0.93 for subject 2, and the nonoverlap of all pairs indices for the nonparetic hand were calculated, respectively, as 0.92 and 1. CONCLUSION We provide empirical evidence in support of a new simple Virtual Rehabilitation system in CP patient to improve upper-limb motor function.

Abstract
Contrary to the expectations articulated in public policy, restrictive interventions are commonly used in support services for people with developmental disabilities. This systematic review and quantitative synthesis was undertaken to investigate whether the use of seclusion and restraints on people with developmental disabilities can be reduced. Searches of the Academic Search Complete, CINAHL, MEDLINE, and PsycINFO electronic databases returned 7226 records, of which 11 met the inclusion criteria for this review. A further 3 papers were obtained through scanning the reference lists of those articles included from the initial literature search. All 14 studies were single-subject designs focusing on initiatives to reduce physical or mechanical restraint. Between the baseline and intervention phases, there were mean reductions in the frequency and duration of restraint use of 79% (SD=21%, n=13 subjects from 7 studies) and 45% (SD=58%, n=10 subjects from 6 studies), respectively. For studies in which restraint use to manage agitation and aggression was targeted, there was a 79% (SD=21%, n=13 subjects from 7 studies) decrease in the frequency and a 28% (SD=67%, n=6 subjects from 3 studies) reduction in the duration of restraint. With respect to studies in which restraint use to prevent self-harm was targeted, there was a 71% (SD=34%, n=4 subjects from 3 studies) reduction in restraint use. Effect sizes were calculable, using non-overlap approaches, for 9 of the 14 studies. The magnitudes of the effect sizes suggest that, on average, the interventions were effective in reducing the use of restraints. The effects generated in studies where restraint use for self-harm was targeted were typically more pronounced than those in which restraint use for agitation and aggression was addressed. There were broad variations, however, in the percentage reductions in restraint use and in the magnitudes of the effect sizes. Although the findings of this review are encouraging, more research is needed, in which greater attention must be paid to rigorous research design, application, and analysis.

Abstract
On the basis of review of the published literature,limitations in current data do not support the use ofa gluten-free and casein-free diet (gfcf-d) asa primary autism spectrum disorder (ASD) treatment.(13)(25)(26)(36) On the basis of clinical opinion, given the popularity of parents seeking a gfcf-d for their children with ASD, clinicians should acknowledge family’s concerns and provide appropriate information about a gfcf-d toguide them and prevent possible harm.

Abstract
Twenty-three studies identified from a previous systematic review examining the effects of communication partner training on persons with aphasia and their communication partners were evaluated for methodological quality. Two reviewers rated the studies on defined methodological quality criteria relevant to each study design. There were 11 group studies, seven single-subject participant design studies, and five qualitative studies. Quality scores were derived for each study. The mean inter-rater reliability of scores for each study design ranged from 85-93%, with Cohen's Kappa indicating substantial agreement between raters. Methodological quality of research on communication partner training in aphasia was highly varied. Overall, group studies employed the least rigorous methodology as compared to single subject and qualitative research. Only two of 11 group studies complied with more than half of the quality criteria. No group studies reported therapist blinding and only one group study reported participant blinding. Across all types of studies, the criterion of treatment fidelity was most commonly omitted. Failure to explicitly report certain methodological quality criteria may account for low ratings. Using methodological rating scales specific to the type of study design may help improve the methodological quality of aphasia treatment studies, including those on communication partner training.

Abstract
Neuropsychological rehabilitation is concerned with the amelioration of cognitive, emotional, psychosocial, and behavioural deficits caused by an insult to the brain. Major changes in the field have occurred over the past decade or so. In 2011, Wilson published an article titled ‘Cutting edge developments in neuropsychological rehabilitation and possible future directions’, in which 10 of the most important changes in neuropsychological rehabilitation over the previous 5 years were described. This article is an update of those changes: some of the topics in the 2011 article have been omitted, others added, and the order of importance has been changed. For the most part, the developments described relate to the rehabilitation of adults with non-progressive brain injury, the exceptions being a development for people with dementia and another relates to children. Topics considered are new assessment procedures, new treatment strategies for cognitive and emotional problems, recognition of the need to find new ways to evaluate the efficacy of rehabilitation, and evidence for the effectiveness of comprehensive-holistic rehabilitation.

Abstract
BACKGROUND/AIM Providing a wheelchair or scooter is a complex therapy intervention aimed at enhancing the person's functioning. The research and experience has shown that a wheelchair which is poorly matched to the individual, adversely affects potential activities and participation, lifestyle goals, health status and can be costly. The development of an evidence-based clinical guideline will provide a synthesis of the evidence and recommendations for best practice. METHODS The guidelines were developed using a rigorous methodology of systematic search for primary studies, critical appraisal and synthesis of the evidence using an adaptation of the National Health and Medical Research Council recommendation grades in conjunction with a multidisciplinary working party. RESULTS Seventy-six recommendations were developed from 44 clinical questions related to goals, assessment and review, capacity and performance, upper limb capacity and injury risk, wheelchair features, propulsion, training, transport and maintenance. Resources were developed to support the use of the guidelines. Only examples of recommendations are provided here. The complete guidelines and technical report should be downloaded from http://www.lifetimecare.nsw.gov.au/Brain_Injury.aspx. CONCLUSION The guidelines provide appraisal and synthesis of the literature and recommendations for best practice on the prescription of a wheelchair or scooter for adults with spinal cord injury and/or traumatic brain injury. The guidelines are intended to reduce the potential for poor wheelchair prescription, inform and guide practice to enhance outcomes. Through judicious application of the available research, these guidelines provide best practice recommendations for prescribing the most appropriate wheelchair for a person with a traumatic brain injury/spinal cord injury.

Abstract
This paper examines the evidence for community and outpatient aphasia groups using the International Classification of Functioning, Disability and Health (ICF) framework. A systematic search of the literature using eight electronic databases was completed; 29 studies met inclusion and exclusion criteria. Level of evidence and methodological quality was assessed and effect sizes calculated where possible. Evidence favouring community and outpatient groups centred on four level ii and level iii-i studies that examined the efficacy of highly structured group activities for improving specific linguistic processes with five medium-large effect sizes calculated. Medium and large effect sizes were also calculated on a level iii-i study examining number of friendships and community access. No effect sizes were available for level ii or level iii studies examining communication activity and participation. Overall, the results indicate that community and outpatient group participation can improve specific linguistic processes. There is also some evidence that group participation can benefit social networks and community access. However, there is limited evidence demonstrating improvement in functional communication as a consequence of group participation. The current evidence is not comprehensive. Further well-designed studies, particularly examining activity and participation, and contextual factors are required to advance community and outpatient aphasia group practice and participation.

Abstract
The goal of this paper is to discuss experimental design options available for establishing the effects of treatment in studies that aim to examine the neural mechanisms associated with treatment-induced language recovery in aphasia, using functional magnetic resonance imaging (fMRI). We present both group and single-subject experimental or case-series design options for doing this and address advantages and disadvantages of each. We also discuss general components of and requirements for treatment research studies, including operational definitions of variables, criteria for defining behavioral change and treatment efficacy, and reliability of measurement. Important considerations that are unique to neuroimaging-based treatment research are addressed, pertaining to the relation between the selected treatment approach and anticipated changes in language processes/functions and how such changes are hypothesized to map onto the brain.

Abstract
OBJECTIVE The purpose of the current study was to evaluate the feasibility and the effectiveness of the use of a customized personal digital assistant (PDA) to support cognitive functioning in a person with Korsakoff syndrome. METHOD The PDA was compared with no external support and the use of a memory watch in a single case experimental design. Three main personal goal tasks were defined: "arrive at appointments on time", "execute a long-term task successfully", and "remember to ask for medication". RESULTS No significant differences were found between the use of the memory watch and the use of the customized PDA. PDA use was perceived as feasible and effective and was considered as a more comprehensive aid than the memory watch. CONCLUSION This study shows that a person with Korsakoff syndrome is able to use and benefit from a customized PDA. Replication of these findings in a larger effectiveness study is necessary.

Abstract
PURPOSE To determine if Goal Management Training (GMT) is effective for the rehabilitation of executive functions following brain injury when administered alone or in combination with other interventions. METHOD Systematic review, with quality appraisal specific to executive functions research and calculation of effect sizes. RESULTS Twelve studies were included. Four studies were "Proof-of-principle" studies, testing the potential effectiveness of GMT and eight were rehabilitation studies. Effectiveness was greater when GMT was combined with other interventions. The most effective interventions appeared to be those combing GMT with: Problem Solving Therapy; personal goal setting; external cueing or prompting apply GMT to the current task; personal homework to increase patients' commitment and training intensity; ecological and daily life training activities rather than paper-and-pencil, office-type tasks. Level of support for GMT was higher for studies measuring outcome in terms of increases in participation in everyday activities rather than on measures of executive impairment. CONCLUSION Comprehensive rehabilitation programs incorporating GMT, but integrating other approaches, are effective in executive function rehabilitation following brain injury in adults. There is insufficient evidence to support use of GMT as a stand-alone intervention.

Abstract
Technology-based interventions to promote health are expanding rapidly. Assessing the preliminary efficacy of these interventions can be achieved by employing single-case experiments (sometimes referred to as n-of-1 studies). Although single-case experiments are often misunderstood, they offer excellent solutions to address the challenges associated with testing new technology-based interventions. This paper provides an introduction to single-case techniques and highlights advances in developing and evaluating single-case experiments, which help ensure that treatment outcomes are reliable, replicable, and generalizable. These advances include quality control standards, heuristics to guide visual analysis of time-series data, effect size calculations, and statistical analyses. They also include experimental designs to isolate the active elements in a treatment package and to assess the mechanisms of behavior change. The paper concludes with a discussion of issues related to the generality of findings derived from single-case research and how generality can be established through replication and through analysis of behavioral mechanisms.

Aphasia rehabilitation: does generalisation from anomia therapy occur and is it predictable? A case series study. Cortex 2013; 49:2345-57. [PMID: 23608067 DOI: 10.1016/j.cortex.2013.01.005] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2012] [Revised: 10/31/2012] [Accepted: 12/03/2012] [Indexed: 11/23/2022]
Abstract
INTRODUCTION The majority of adults with acquired aphasia have anomia which can respond to rehabilitation with cues. However, the literature and clinical consensus suggest change is usually limited to treated items. We investigated the effect of an experimentally controlled intervention using progressive cues in the rehabilitation of noun retrieval/production in 16 participants with chronic aphasia. METHOD Participants were sub-divided relative to the group according to performance on semantic tasks (spoken/written word to picture matching) and phonological output processing (presence/absence of word length effect and proportion of phonological errors in picture naming) in order to investigate outcome in relation to language profile. Cueing therapy took place weekly for 8 weeks. RESULTS Intervention resulted in significant improvement on naming treated items for 15/16 participants, with stable performance on control tasks. Change occurred at the point of intervention and not during pre-therapy assessments. We predicted particular patterns of generalisation which were upheld. Only participants classified as having relatively less of a semantic difficulty and more of a phonological output deficit demonstrated generalisation to untreated items. Outcome did not relate to traditional aphasia classification. CONCLUSION A cueing hierarchy can improve word retrieval/production for adults with aphasia. In some cases generalisation to untreated items also occurs. The study demonstrates that the results of behavioural testing can be used to guide predictions of recovery with intervention.

Abstract
This article systematically reviews the research design and methodological characteristics of single-case experimental design (SCED) research published in peer-reviewed journals between 2000 and 2010. SCEDs provide researchers with a flexible and viable alternative to group designs with large sample sizes. However, methodological challenges have precluded widespread implementation and acceptance of the SCED as a viable complementary methodology to the predominant group design. This article includes a description of the research design, measurement, and analysis domains distinctive to the SCED; a discussion of the results within the framework of contemporary standards and guidelines in the field; and a presentation of updated benchmarks for key characteristics (e.g., baseline sampling, method of analysis), and overall, it provides researchers and reviewers with a resource for conducting and evaluating SCED research. The results of the systematic review of 409 studies suggest that recently published SCED research is largely in accordance with contemporary criteria for experimental quality. Analytic method emerged as an area of discord. Comparison of the findings of this review with historical estimates of the use of statistical analysis indicates an upward trend, but visual analysis remains the most common analytic method and also garners the most support among those entities providing SCED standards. Although consensus exists along key dimensions of single-case research design, and researchers appear to be practicing within these parameters, there remains a need for further evaluation of assessment and sampling techniques and data analytic methods.

Abstract
The growth of evidence-based medicine means that both researchers and clinicians must grasp the complex issues involved in implementing clinical trials, which are especially challenging for the behavioral (experience-based) treatments that predominate in rehabilitation. In this article we discuss selected issues germane to the design, implementation, and analysis of group-level clinical trials in rehabilitation. We review strengths, weaknesses, and best applications of 1-sample, between-subjects, and within-subjects study designs, including newer models such as practical clinical trials and point-of-care trials. We also discuss the selection of appropriate control conditions against which to test rehabilitation treatments, as well as issues related to trial blinding. In a section on treatment definition, we discuss the challenges of specifying the active ingredients in the complex interventions that are widely used in rehabilitation, and present an illustration of 1 approach to defining treatments via the learning mechanisms that underlie them. Issues related to treatment implementation are also discussed, including therapist allocation and training, and assessment of treatment fidelity. Finally we consider 2 statistical topics of particular importance to many rehabilitation trials: the use of multiple or composite outcomes, and factors that must be weighed in estimating sample size for clinical trials.

Abstract
Cognitive neuropsychology has championed the use of single-case research design. Recently, however, case series designs that employ multiple single cases have been increasingly utilized to address theoretical issues using data from neuropsychological populations. In this paper, we examine these methodologies, focusing on a number of points in particular. First we discuss the use of dissociations and associations, often thought of as a defining feature of cognitive neuropsychology, and argue that they are better viewed as part of a spectrum of methods that aim to explain and predict behaviour. We also raise issues regarding case series design in particular, arguing that selection of an appropriate sample, including controlling degree of homogeneity, is critical and constrains the theoretical claims that can be made on the basis of the data. We discuss the possible interpretation of “outliers” in a case series, suggesting that while they may reflect “noise” caused by variability in performance due to factors that are not of relevance to the theoretical claims, they may also reflect the presence of patterns that are critical to test, refine, and potentially falsify our theories. The role of case series in treatment research is also raised, in light of the fact that, despite their status as gold standard, randomized controlled trials cannot provide answers to many crucial theoretical and clinical questions. Finally, we stress the importance of converging evidence: We propose that it is conclusions informed by multiple sources of evidence that are likely to best inform theory and stand the test of time.

Abstract
PURPOSE Pain associated with hypermobility of wrist and hand joints can contribute to decreased handwriting output. This study examined the effectiveness of a neoprene wrist/hand splint in reducing pain and increasing handwriting speed and endurance for students with joint hypermobility syndrome. METHODS Multiple baseline, single system design (SSD) methodology was used. Four ninth grade students with handwriting difficulties because of joint hypermobility syndrome participated in this study. RESULTS Visual and statistical (two standard deviation band method) analyses indicated a significant decrease in handwriting speed when using the splint for three out of four participants. No significant change in pain or endurance was noted during intervention. There was a significant decrease in pain following withdrawal of the splint for three participants. CONCLUSION Evidence from this study does not support use of this particular splint for decreasing pain and increasing handwriting speed and endurance for ninth grade students with joint hypermobility syndrome.

Abstract
The purpose of this review was to synthesize the research underlying group contingency interventions to determine whether there is sufficient evidence to support their use for managing the classroom behavior of students with behavioral difficulties. An application of the What Works Clearinghouse (WWC) procedures for evaluating single-subject research revealed that the research investigating group contingencies demonstrated sufficient rigor, evidence, and replication to label the intervention as evidence-based. These findings were further supported across five quantitative indices of treatment effect. The results associated with the application of the WWC procedures and quantitative evaluations were supplemented with additional systematic coding of methodological features and study characteristics to evaluate the populations and conditions under which the effects of the group contingency best generalize. Findings associated with this coding revealed that the lack of detailed reporting across studies limited our ability to determine for whom and under what conditions group contingencies are best suited.

Abstract
Although cognitive-behavioural therapy (CBT) is the treatment of choice for anxiety, its delivery needs to be adapted for individuals with traumatic brain injury (TBI). It also requires clients' active engagement for maximum benefit. This study was a pilot randomised controlled trial involving an anxiety treatment programme adapted for people with TBI, based on CBT and motivational interviewing (MI). Twenty-seven participants with moderate/severe TBI (aged 21-73 years, 78% males) recruited from a brain injury rehabilitation hospital were randomly allocated to receive MI + CBT (n = 9), non-directive counselling (NDC) + CBT (n = 10) and treatment-as-usual (TAU) (n = 8). CBT and MI were manualised and delivered in 12 weekly individual sessions. Primary outcome was self-reported anxiety symptoms assessed at baseline, at the end of NDC/MI and immediately following CBT. Assessment was conducted by assessors blinded to group assignment. Intention-to-treat analyses showed that the two active treatment groups demonstrated significantly greater anxiety reduction than TAU. Participants receiving MI showed greater response to CBT, in terms of reduction in anxiety, stress and non-productive coping, compared to participants who received NDC. The results provided preliminary support for the adapted CBT programme, and the potential utility of MI as treatment prelude. Longer follow-up data are required to evaluate the maintenance of treatment effects.

Abstract
PURPOSE Untreated behavioural and cognitive changes after primary brain tumour (PBT) can result in challenging behaviours (CBs), with limited documentation on treatment approaches. This study explored the feasibility of employing a Behavioural Consultancy approach to manage CBs, targeting individuals with PBT, family and treating staff. METHODS Participants were patients and families of two hospitals and health professionals from cancer/neurological services. A single-case experimental design piloted skill-based training and environmental changes in managing socio-behavioural impairments in a person with a low grade astrocytoma. A half-day workshop to train family members (n = 7) in compensatory strategy use to manage CBs after PBT was piloted. Finally, a 1-day workshop was provided to 43 health professionals in managing CBs after PBT. For both workshops, a pre-post impact evaluation was conducted employing a purpose-designed Strategies Use Measure. RESULTS All three interventions demonstrated positive results. The single case showed a 71% decrease in the target behaviour (time spent talking) post-intervention. Some attrition to these gains was observed at two follow-up time points (3 and 5 months). Participants from both workshops demonstrated significant post-intervention increases in perceived knowledge of Strategy Use (family members z = 2.03, p < 0.05; health professionals z = 4.95, p < 0.00; Wilcoxon signed-rank test). CONCLUSIONS These initial studies highlight the potential of employing an integrated multi-tiered intervention based on a Behavioural Consultancy model to manage CBs after PBT.

Abstract
The effectiveness of different interventions for challenging behavior (CB) in persons with intellectual disabilities (ID) was reviewed by means of a two-phase study. First, a systematic review of 137 meta-analyses and reviews on group-study interventions for CB in persons with ID was conducted. Based on this review, hypotheses concerning the effectiveness of divergent interventions for CB and concerning the impact of variables moderating treatment effectiveness were systematically generated. Second, these hypotheses were tested by means of a multilevel meta-analysis of single-case and small-n research. Two hundred and eighty-five studies reporting on 598 individuals were examined. The average treatment effect was large and statistically significant. However, this effect varied significantly over the included studies and participants. Compared to the meta-analyses and reviews focusing on group-studies in this research domain, the results of the present multilevel meta-analysis of single-case and small-n intervention research provided more detailed knowledge on which specific CB and intervention components moderate the interventions' effectiveness.

Abstract
AbstractAcceptance and commitment therapy (ACT) is increasingly used in clinical practice to manage anxiety conditions. This psychotherapeutic approach focuses on the following: (1) acceptance of an individual's experience of the spectrum of psychological and emotional states, (2) choosing valued direction for the individual's life, and (3) commitment to action that leads the individual in the direction of those values. This article presents an empirical review of ACT for treatment of anxiety in two parts. In the first part we systematically review the literature for studies examining ACT for anxiety management in the general population with anxiety problems. In the second part, we discuss applicability of acceptance-based approaches for a health population in which these techniques may have applicability, that is, for people with acquired brain injury (ABI). Electronic searches for the review were conducted on PsycINFO and Medline. Inclusion criteria were as follows: (1) used an ACT intervention study, (2) the target of the intervention was an anxiety disorder or anxiety symptomatology, (3) the intervention used a randomised controlled trial (RCT) or single case experimental design (SCED) methodology, and (4) the paper was available in English. Studies were rated for methodological quality using standardised assessment procedures. Four RCTs provided support for ACT for obsessive compulsive disorder (OCD), maths anxiety, trichotillomania (TTM), and mixed anxiety and depression. Three SCED trials scoring in the high range on the scale of methodological quality revealed some support for ACT for managing TTM, skin picking, and OCD. Although no studies were identified that investigated ACT for managing anxiety in people with ABI, the review highlights issues for consideration when applying ACT in this population.

Abstract
AbstractThis article considers 10 of the most important developments in neuropsychological rehabilitation over the past 5 years. While several leaders in the field were contacted to discover what they considered to be the most important developments, the selection discussed here is the author's alone and is, therefore, a personal view. Included are: computational models; support for people with dementia; new assessment procedures; new treatment strategies for cognitive, emotional and psychosocial problems; new theoretical models to improve our understanding of the consequences of brain injury; and recognition of the need to find new ways to evaluate the efficacy of rehabilitation. The final section of the article considers possible future developments in rehabilitation, including stronger links with basic neuro-science; better use of imaging procedures; collaboration with pharmaceutical companies; better evaluation of our programs; and the need to educate researchers and practitioners as to the meaning of rehabilitation.

Abstract
AbstractIn this special article we describe a number of reporting guidelines endorsed by the CONSORT (Consolidated Standards of Reporting Trials) group for a range of research designs that commonly appear in scientific journals: systematic reviews, clinical trials with and without randomisation, observational studies, n-of-1 (or single-case experimental design) trials, and diagnostic studies. We also consider reporting guidelines for studies using qualitative methodology. In addition to reporting guidelines, we present method quality rating scales, which aim to measure risk of bias that threatens the internal validity of a study. Advantages of reporting guidelines and method quality rating scales for authors include the provision of a structure by which to improve the clarity and transparency of report writing; for reviewers and readers advantages include a method by which to critically appraise an article.Brain Impairmentendorses these reporting guidelines and applies them within the review process for submissions to the journal.

Abstract
The objective of this pilot study was to investigate how a memory training technique called "Spaced Retrieval" (SR) might be effectively applied in helping persons with Alzheimer's disease improve their recall of recent events. Capitalising on the interdependence among spared and impaired memory systems, it was hypothesised that SR training with support at encoding and retrieval would facilitate the retention and recall of meaningful recent events. Eight participants with a diagnosis of Alzheimer's disease or related disorder were recruited for this study. The study employed a quasi-experimental multiple baseline treatment design across participants, items, and behaviours. SR training was provided in three domains: Semantic, Prospective, and Episodic recent memory. The results show important training gains made by all participants across conditions at post-training follow-up. In the Episodic condition, participants were able to recall specific details about recent events following training. This study provides preliminary evidence that individuals with mild to severe cognitive impairment can learn and recall new episodic information through Spaced Retrieval training. If replicated, these findings would support the use of Spaced Retrieval as an intervention tool to help individuals maintain their functioning in the area of episodic recent memory.

Abstract
The relationship between assistive technology for cognition (ATC) and cognitive function was examined using a systematic review. A literature search identified 89 publications reporting 91 studies of an ATC intervention in a clinical population. The WHO International Classification of Functioning, Disability and Health (ICF) was used to categorize the cognitive domains being assisted and the tasks being performed. Results show that ATC have been used to effectively support cognitive functions relating to attention, calculation, emotion, experience of self, higher level cognitive functions (planning and time management) and memory. The review makes three contributions: (1) It reviews existing ATC in terms of cognitive function, thus providing a framework for ATC prescription on the basis of a profile of cognitive deficits, (2) it introduces a new classification of ATC based on cognitive function, and (3) it identifies areas for future ATC research and development.

Abstract
OBJECTIVE To investigate the use of a novel study design in analysis of bilateral elbow pain. DESIGN N of 1, two contemporary arm, open label, randomised controlled clinical trial. SETTING A clinical epidemiologist at a university hospital in Pavia, Italy. PARTICIPANTS Two elbows with epicondylitis. INTERVENTIONS Autologous platelet lysate versus "wait and see" strategy. MAIN OUTCOME MEASURES Visual analogue scale for pain on elbow extension and resisted wrist extension. RESULTS Over six months' follow-up, the patient experienced bilateral improvement in pain, but higher in the treated arm, with a drop in visual analogue scale for pain from 28 to 4 for right (control) arm (drop of 24 points) and from 67 to 10.5 for left (treated) arm (drop of 56.5 points). CONCLUSIONS Platelet lysate might (or might not) work. Competing interests and lack of blinding might be relevant issues in the interpretation of trial results. However, the new study design can be applied to a number of conditions such as bilateral sport or trauma injuries, bilateral otitis, or any condition affecting chiral organs or limbs.
