Developing a common metric using current scales for assessing functioning in patients with knee osteoarthritis.

Objectives: Various scales exist to assess different domains of functioning in knee osteoarthritis (OA). This study aimed to explore whether it is possible to develop a common metric (CM) from the frequently used scales to assess functioning in knee OA. Patients and methods: The methodological study evaluated 411 patients (81 males, 330 females; mean age: 61.8±10.5 years; range, 41 to 88 years) with knee OA. Data from the Health Assessment Questionnaire, Oxford Knee Score, Medical Outcomes Study Short Form 36, Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Arthritis Index, and the Nottingham Health Profile were used, and the items focusing on self-care, mobility, and domestic activity domains based on the activities and participation component of the International Classification of Functioning, Disability, and Health were included. Concurrent calibration was performed to combine the items of the scales. The CM parameters were estimated using the Rasch measurement model. Reliability was assessed using the person separation index. The CM was utilized to generate a transformation table to convert the scale scores to each other based on the reference metric score. Results: Each scale fitted the Rasch model. Item invariance was achieved for the CM (p=0.775). The CM had a person separation index of 0.827. Age, sex, and disease duration did not cause difference in item functions. The CM satisfied the assumptions of unidimensionality and local independence. Conclusion: A reliable CM was created from the commonly used scales to measure functioning in individuals with knee OA. Thus, clinicians and researchers can refer to the transformation table to directly compare scores of those scales and use them interchangeably.

Application of the Rasch measurement model in rehabilitation research and practice: early developments, current practice, and future challenges.

The application of the Rasch measurement model in rehabilitation is now well established. Both its dichotomous and polytomous forms provide for transforming ordinal scales into interval-level measures, consistent with the requirements of fundamental measurement. The growth of applying the model in rehabilitation spans 30 years, during which both the protocol has steadily developed and several software packages have emerged that provide for analysis, together with the "R" language that has an increasing set of codes for applying the model. This article reviews that development and highlights current practice requirements, including those for providing the relevant information for the methods, and what is expected of the analysis. In addition, this provides a worked example and looks at the remaining issues and current developments of its application.

Rehabilitation interventions in osteoarthritis.

The goals of the management of osteoarthritis (OA) are to relieve joint pain and stiffness, maintain or increase joint mobility and stability, improve activities and participation, and enhance quality of life. The first step in the management is to make a comprehensive holistic assessment to understand the impact of the disease on the individual. Then, an individualized management plan can be set via a shared-decision making process between the patient and the clinician taking into account all components of functioning affected by the disease. Rehabilitation interventions serve as the basis of OA management whereas pharmacological modalities are usually administered for additional symptom control. This study aimed to overview the rehabilitation interventions used for people with OA with an update of the recent evidence. First, core management approaches that include patient education, physical activity and exercises, and weight loss were addressed; then adjunctive treatments including biomechanical interventions (e.g. orthoses, assistive devices) and physical modalities were overviewed.

Validation of the Pediatric Quality of Life Inventory 3.0 Cerebral Palsy Module (Parent Form) for use in Türkiye.

Objectives: This study was planned to test the reliability and validity of the Turkish version of the Pediatric Quality of Life Inventory (PedsQL) 3.0 cerebral palsy (CP) module (parent form) in children with CP. Patients and methods: In the validation study conducted between June 2007 and June 2009, 511 children (299 normal children, 212 children with CP) were assessed by the seven scales of PedsQL [daily activities (DA), school activities (SA), movement and balance (MB), pain and hurt (PH), fatigue (F), eating activities (EA), and speech and communication (SC)]. Reliability was tested by internal consistency and person separation index (PSI); internal construct validity by Rasch analysis and external construct validity by correlation with the Gross Motor Function Classification System (GMFCS) and Functional Independence Measure for Children (WeeFIM). Results: Only 13 children with CP completed the inventory by themselves and thus were excluded. Consequently, 199 children with CP (113 males, 86 females; mean age: 7.3±4.2 years; range, 2 to 18 years) and 299 normal children (169 males, 130 females; mean age: 9.4±4.0 years; range, 2 to 17 years) were included in the final analysis. Reliabilities of the seven scales of the PedsQL 3.0 CP module were adequate, with Cronbach's alphas between 0.66 and 0.96 and the PSI between 0.672 and 0.943 for the CP group. In Rasch analysis, for each scale, items showing disordered thresholds were rescored; then testlets were created to overcome local dependency. Internal construct validity of the unidimensional seven scales was good with the mean item fit of -0.107±1.149, 0.119±0.818, 0.232±1.069, -0.442±0.672, 0.221±0.554, -0.091±0.606, and -0.333±1.476 for DA, SA, MB, PH, F, EA, and SC, respectively. There was no differential item functioning. External construct validity of the instrument was confirmed by expected moderate to high correlations with WeeFIM and GMFCS (Spearman's r=0.35-0.89). Conclusion: Turkish version of the PedsQL 3.0 CP module is reliable, valid, and available for use in clinical setting to evaluate health-related quality of life of children with CP.

Development of simple descriptions of the ICF Generic-30 Set in different languages: laying the foundation for an ICF-based clinical tool for Europe.

BACKGROUND: Functioning is considered a third indicator of health and a key outcome in rehabilitation. A universal practical tool for collecting functioning information is essential. This tool would be ideally based on the International Classification of Functioning, Disability and Health. AIM: To report the results of the development of country/language-specific versions of an ICF-based clinical tool in six European countries. DESIGN: Consensus process. SETTING: Expert conferences. POPULATION: Multi-professional group of rehabilitation professionals in six European countries. METHODS: 1) Developed an initial proposal by translating the published English-language version of the simple descriptions into the targeted language; 2) conducted a multi-stage consensus conference to finalize the descriptions; 3) employed a three-stage multi-professional expert panel translation back to English. The consensus conference model was modified for geographically large countries. RESULTS: Croatian, Flemish/Dutch, Greek, Polish, and Turkish versions were produced. CONCLUSIONS: The creation of the country/language-specific simple descriptions is a significant part of the "system-wide implementation of the ICF" initiative that will pave the way for the implementation of the ICF in national health systems. CLINICAL REHABILITATION IMPACT: The practical ICF-based clinical tool with country/language specific versions for standardized reporting of functioning will serve as a means of integrating functioning information in national health systems and additionally for monitoring the effects of rehabilitation interventions.

Overview of Cochrane Systematic Reviews of rehabilitation interventions for persons with rheumatoid arthritis: a mapping synthesis.

The aim of this paper was to provide an overview of Cochrane Systematic Reviews (CSRs), which synthesizes the quality and quantity of available evidence on the effectiveness of rehabilitation interventions in rheumatoid arthritis (RA). The World Health Organization (WHO) requested Cochrane Rehabilitation the CSRs search to develop the Package of Interventions in Rehabilitation (PIR). We searched the Cochrane Library using the terms "rheumatoid arthritis" and "rehabilitation." We screened the CSRs according to the search strategy based on the methodology developed for the WHO PIR. The search period for the data provided to WHO was between 1 September 2009 and 2019. We updated the search to 1 September 2022 for this paper. We summarized the CSRs identified after the screening process using an evidence map, grouping outcomes, and comparisons of included CSRs indicating the effect and the quality of evidence to provide a comprehensive view of current knowledge. We identified 10 CSRs, including 92 primary studies with 10,801 participants and 23 comparisons. They explored the effectiveness and/or safety of either non-pharmacological or pharmacological (for symptom control only) interventions. Outcomes were pain, muscle strength, grip/pinch strength, tender joints, swollen joints, fatigue, disease activity, radiological damage, physical function, hand function, participant adherence, clinical improvement, withdrawals, and adverse events. Our mapping synthesis indicates that physical activity and exercises in RA are effective non-pharmacological interventions for some outcomes, such as hand function, muscle strength and fatigue, without any deterioration of pain, disease activity and radiological involvement. Psychosocial interventions show a small beneficial effect on fatigue. Regarding pharmacological agents, celecoxib presents similar analgesic effects with traditional NSAIDs but fewer gastric adverse events. Current evidence supports physical activity and exercise programs for individuals with RA. However, well-designed studies will help document the exact effects of these programs on different outcomes and physiological mechanisms in RA. There were inconclusive results for some of the interventions due to low and very-low quality of evidence. Furthermore, due to the lack of CSRs on therapeutic patient education, orthoses, physical modalities and assistive devices in the search period, it was impossible to synthesise the evidence on those interventions.

Effectiveness of pulsed electromagnetic field therapy in the management of complex regional pain syndrome type 1: A randomized-controlled trial.

Objectives: This study aims to investigate whether pulsed electromagnetic field (PEMF) therapy in addition to a conventional rehabilitation program is effective on pain and functioning in patients with type 1 complex regional pain syndrome (CRPS-1) of the hand. Patients and methods: Between March 2013 and January 2015, a total of 32 patients (16 males, 16 females; mean age: 50.1±13.1 years; range, 25 to 75 years) were included. The patients were randomly allocated into two groups. The control group (n=16) received a conventional rehabilitation program consisting of physical modalities, exercises, and occupational therapy, whereas the PEMF group (n=16) received additional PEMF (8 Hz, 3.2 mT) to the affected hand. The primary outcome measure was pain intensity using the Numeric Rating Scale (NRS). Secondary outcome measures were grip and pinch strength, hand edema, hand dexterity, and hand activities. All patients received 20 therapy sessions (five sessions/week, four weeks in total) and were evaluated before and after the therapy and at the first-month follow-up. Results: Both groups showed significant improvements in primary and secondary outcomes (p<0.05) after the therapy and at follow-up. When the groups were compared in terms of improvements in assessment parameters, no statistically significant difference was found between the two groups in any of the outcomes (p>0.05). Conclusion: The PEMF in addition to conventional rehabilitation program did not provide additional benefit for pain and hand functions in CRPS-1. Future studies using different application parameters such as frequency, intensity, duration, and route may provide a better understanding of the role of PEMF in CRPS-1 treatment.

Scale Banking for Patient-Reported Outcome Measures That Measure Functioning in Rheumatoid Arthritis: A Daily Activities Metric.

OBJECTIVE: Functioning is an important outcome for the management of rheumatoid arthritis (RA). Heterogeneity of respective patient-reported outcome measures (PROMs) challenges direct comparisons between their results. This study aimed to standardize reporting of such PROMs measuring functioning in RA to facilitate comparability. METHODS: Common-item nonequivalent group design with the Health Assessment Questionnaire (HAQ) as a common scale across data sets from various countries (including the UK, Turkey, and Germany) to establish a common metric was used. Other PROMs included are the physical function items of the Multidimensional HAQ (MDHAQ), the Disabilities of the Arm, Shoulder, and Hand questionnaire, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the World Health Organization Disability Assessment Schedule II (WHODAS II), the Medical Outcomes Study Short Form 36 (SF-36) health survey, and 4 short forms (20, 10, 6, and 4 physical function items) from the Patient-Reported Outcomes Measurement Information System. As the HAQ includes mobility, self-care, and domestic life items, this study focuses on these 3 domains. PROMs were described using standard error of measurement (SEM) and smallest detectable difference (SDD). A Rasch measurement model was used to create the common metric. RESULTS: The range of the SEM was 0.2 (MDHAQ) to 7.4 (SF-36 health survey physical functioning domain). The SDD revealed a range from 9.7% (WOMAC rating scale) to 33.5% (WHODAS physical functioning domain). PROMs co-calibration revealed fit to the Rasch measurement model. A transformation table was developed to allow exchange between PROM scores. CONCLUSION: Scores between the daily activity PROMs commonly used in RA can now be compared. Factors such as SEM and SDD help to determine the choice of a PROM in clinical practice and research.

Is it possible to develop a new measurement tool to assess the functional status in patients with rheumatoid arthritis?

OBJECTIVES: This study aims to develop measurement tools for assessing patients' functional status with rheumatoid arthritis (RA) in terms of upper and lower extremity function and to evaluate the tools' construct validities with classical and modern psychometric approaches. PATIENTS AND METHODS: Between April 2010 and April 2012, a total of 300 patients with RA (77 males, 223 females; mean age: 52.3±11.5 years; range, 18 to 82 years) who answered items from a range of widely used instruments were included. After examining initial dimensionality with exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Rasch analysis were used to evaluate the tools' construct validities. The data-model fit was evaluated with goodness-of-fit (GoF) statistics in CFA, while the tools were examined in terms of item and person fit, unidimensionality and differential item functioning (DIF) from the perspective of Rasch analysis. RESULTS: According to EFA, two dimensions were identified and named as "self-care-mobility-household activities related to lower extremity" and "self-care-mobility-household activities related to upper extremity" taking into account the factor loadings and the clinical classifications. While the clinical classification was tested with CFA, all items were loaded on their pre-defined dimensions with the factor loadings of ≥0.40 and GoF statistics were within the acceptable ranges. When the "self-care-mobility-household activities related to upper extremity" and "self-care-mobility-household activities related to lower extremity" tools were evaluated via the Rasch analysis, both tools were found to fit the Rasch model expectations, with a mean item fit statistics of -0.528 logit (standard deviation [SD]: 1.365) and -0.213 (SD: 1.168; mean person fit statistics of -0.412 logit (SD: 1.160) and -0.303 logit (SD: 0.859), respectively. CONCLUSION: For the evaluation of a scale's construct validity, it is recommended to use the Rasch analysis in tandem with factor analytic methods, as the Rasch analysis explores a scale's construct validity in terms of item and person fit, DIF and unidimensionality which is the only aspect of the factor analysis.

Use and detailed metric properties of patient-reported outcome measures for rheumatoid arthritis: a systematic review covering two decades.

INTRODUCTION: The importance of patient-reported outcome measures (PROMs) for rheumatoid arthritis (RA) clinical studies has been recognised for many years. The current study aims to describe the RA PROMs used over the past 20 years, and their performance metrics, to underpin appropriate tool selection. METHODS: The study included a systematic search for PROMs that have been in use over the period 2000-2019, with detailed documentation of their psychometric properties, and a user-friendly presentation of the extensive evidence base. RESULTS: 125 PROMs were identified with psychometric evidence available. The domains of pain, fatigue, emotional functions, mobility, physical functioning and work dominated, with self-efficacy and coping as personal factors. Domains such as stiffness and sleep were poorly served. The most frequently used PROMs included the Health Assessment Questionnaire Disability Index (HAQ), the Short Form 36 (SF-36), the EuroQoL and the Modified HAQ which, between them, appeared in more than 3500 papers. Strong psychometric evidence was found for the HAQ, and the SF-36 Physical Functioning and Vitality (fatigue) domains. Otherwise, all domains except stiffness, sleep, education and health utility, had at least one PROM with moderate level of psychometric evidence. CONCLUSION: There is a broad range of PROMs for measuring RA outcomes, but the quality of psychometric evidence varies widely. This work identifies gaps in key RA domains according to the biopsychosocial model.

Does extracorporeal shock wave therapy decrease spasticity of ankle plantar flexor muscles in patients with stroke: A randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of radial extracorporeal shock wave therapy on ankle flexor spasticity in stroke survivors and to reveal changes in the fibroelastic components of muscle. DESIGN: Randomized controlled trial. SETTING: Inpatient neuro-rehabilitation clinic of a university hospital. PARTICIPANTS: Stroke patients with ankle flexor spasticity. INTERVENTIONS: Patients were randomized to three groups; radial extracorporeal shock wave therapy, sham, or control. Active and sham therapy were administered two sessions/week for two weeks. All patients received conventional rehabilitation. MAIN MEASURES: The primary outcome was Modified Ashworth Scale. Secondary outcomes were the Tardieu Scale and elastic properties of plantar flexor muscles assessed by elastography (strain index). All assessments were performed before, immediately after the treatment, and four weeks later at follow-up. RESULTS: Fifty-one participants were enrolled (active therapy n = 17, sham n = 17, control n = 17). Modified Ashworth scores showed a significant decrease in the active therapy group (from 2.47 ± 0.72 to 1.41 ± 0.62) compared to sham (from 2.19 ± 1.05 to 2.06 ± 1.12) and control (from 2.06 ± 0.85 to 2.00 ± 0.73) groups immediately after the treatment (P < 0.001). Tardieu results were also in concordance (P < 0.001), however this effect was not preserved at follow-up. Elastic properties of the ankle flexors were improved in all groups at both assessments after the therapy showing significant decreases in strain index (P < 0.001). However, there was no difference among the groups in terms of improvement in elastography. CONCLUSION: Radial extracorporeal shock wave therapy has short-term anti-spastic effects on ankle flexor muscles when used as an adjunct to conventional rehabilitation.

Current rehabilitation definitions do not allow correct classification of Cochrane systematic reviews: an overview of Cochrane reviews.

BACKGROUND: During the first three years of its work, Cochrane Rehabilitation was faced with the challenge of defining the inclusion and exclusion criteria of what is rehabilitation on four different occasions: when we worked on classifying all Cochrane systematic reviews (CSRs) for relevance to rehabilitation, when we checked for newly published CSRs, when we started the process to set up the reporting guidelines for the Randomized Controlled Trials Rehabilitation Checklist (RCTRACK) project, and during our collaboration with the World Health Organization for the Package of Rehabilitation Interventions. The aim of this paper was to check how the word "rehabilitation" gets used by researchers in the health field. METHODS: This overview of reviews included all CSRs that used the term "rehabilitation" in the title. They were compared with the authors' judgement (AJ) and with the contents of two main sources: CSRs identified by Cochrane Rehabilitation as relevant to rehabilitation (CRDB), and PubMed MeSH term "rehabilitation." We also performed a content analysis classifying all CSRs by field and type of intervention and checked the internal coherence of the two databases in order to verify whether all CSRs on interventions in a specific rehabilitation field were included in the databases or not. RESULTS: Out of 14,816 PubMed entries, we analyzed 89 CSRs. We found four reviews that were judged by all classifications as not rehabilitation: they were related to mouth, nutritional, penile and schizophrenia rehabilitation. While CRDB and AJ included 94% and 91% of CSRs respectively, PubMed included only 50%. One CSR about cardiac rehabilitation was excluded only by CRDB and four by AJ. In the 50% CSRs excluded by PubMed, we found that all CSRs on cancer and vestibular rehabilitation, and those on cognitive and neuropsychological interventions, were always omitted, even if all other CSRs on neurological rehabilitation were included. CONCLUSIONS: Our results clearly highlight the need for a comprehensive rehabilitation definition that is able to point out what should be included and excluded from rehabilitation interventions. This will consequently inform all of Cochrane Rehabilitation's work and will serve the wider community of research and rehabilitation.

Cross-diagnostic scale-banking using rasch analysis: Developing a common reference metric for generic and health condition-specific scales in people with rheumatoid arthritis and stroke.

OBJECTIVES: To develop a common reference metric of functioning, incorporating generic and health condition-specific disability instruments, and to test whether this reference metric is invariant across 2 health conditions. DESIGN: Psychometric study using secondary data analysis. Firstly, the International Classification of Functioning, Disability and Health (ICF) Linking Rules were used to examine the concept equivalence between the World Health Organization Disability Assessment Schedule (WHODAS 2.0), Health Assessment Questionnaire (HAQ) and Functional Independence Measure (FIMTM). Secondly, a scale-bank was developed using a reference metric approach to test-equating, based on the Rasch measurement model. PARTICIPANTS: Secondary analysis was performed on data from 487 people; 61.4% with rheumatoid arthritis and 38.6% with stroke. RESULTS: Three sub-domains of the WHODAS 2.0 and all items of the HAQ and FIMTM motor mapped on to the ICF chapters d4 Mobility, d5 Self-care and d6 Domestic life. Test-equating of these scales resulted in good model fit, indicating that a scale bank and associated reference metric across these 3 instruments could be created. CONCLUSION: This study provides a transformation table to enable direct comparisons among instruments measuring physical functioning commonly used in rheumatoid arthritis (HAQ) and stroke (FIMTM motor scale), as well as in people with disability in general (WHODAS 2.0).

Is there a relationship between venous insufficiency and knee osteoarthritis?

OBJECTIVES: This study aims to evaluate whether there is a relationship between venous insufficiency (VI) and knee osteoarthritis (OA). PATIENTS AND METHODS: Between February 2012 and May 2013, a total of 206 knees of 103 participants (14 males, 89 females; mean age 48.6±8.6 years; range, 30 to 69 years) were enrolled. The study group included 59 patients who were diagnosed with knee OA and the control group included 44 healthy volunteers without any complaint in their knee joints. Demographic and clinical characteristics of all participants were recorded. Venous system of the lower extremities was evaluated by Doppler ultrasonography. All knees were evaluated using conventional radiography based on the Kellgren-Lawrence (K&L) grading system and ultrasonography. Pain severity was evaluated using Likert pain scale and functioning was evaluated using Western Ontorio and McMaster Universities Osteoarthritis Index (WOMAC). RESULTS: Venous insufficiency was detected in 40.6% of the OA group and 15.9% of the control group (p=0.007). There was no statistically significant difference in the cartilage thicknesses and K&L grading regarding the presence of VI (p>0.05); however, the percentage of the radiographic medial tibial sclerosis was higher in patients with VI (60%) in the OA group (p>0.05). The WOMAC total scores were similar in both groups, while the WOMAC pain scores were higher in the patients with deep VI (p>0.05). CONCLUSION: Increased radiographic medial tibial sclerosis and higher WOMAC pain scores in patients with venous involvement in OA may lead to the hypothesis that venous system pathologies can affect the intraosseous microenvironment of the bone, resulting in pain and early subchondral bone involvement, consequently presenting as subchondral sclerosis.

Nonpharmacological treatment in established rheumatoid arthritis.

The goals in the management of established rheumatoid arthritis (RA) are to control pain and disease activity, prevent further joint damage, and enhance functioning and quality of life. Despite the fact that aggressive and the early use of biological and nonbiological disease-modifying antirheumatic drugs have been associated with substantial gains in clinical, radiological, and disability outcomes, a considerable proportion of patients still report significant problems of physical, emotional and social functioning, and unmet needs in established RA. Therefore, nonpharmacological treatments are also administered for patients with RA. The aim of this article is to overview the nonpharmacological, therapeutical, and rehabilitative interventions, to minimize the consequences of the disease in patients with established RA. First, the principles of functional assessment in RA will be addressed. Then nonpharmacological interventions including therapeutic patient education, exercise therapy, physical modalities, orthoses, assistive devices, dietary interventions, and balneotherapy will be reviewed in the light of evidence-based literature data.

Evidence-based position paper on Physical and Rehabilitation Medicine professional practice for persons with stroke. The European PRM position (UEMS PRM Section).

BACKGROUND: Stroke is a major cause of disability worldwide, with an expected rise of global burden in the next twenty years throughout Europe. This EBPP represents the official position of the European Union through the UEMS Physical and Rehabilitation Medicine (PRM) Section and designates the professional role of PRM physicians for people with stroke. The aim of this study is to improve PRM physicians' professional practice for persons with stroke in order to promote their functioning and enhance quality of life. METHODS: A systematic review of the literature including a ten-year period and a consensus procedure by means of a Delphi process has been performed involving the delegates of all European countries represented in the UEMS PRM Section. RESULTS: The systematic literature review is reported together with 78 recommendations resulting from the Delphi procedure. CONCLUSIONS: The professional role of PRM physicians for persons with stroke is to improve specialized rehabilitation services worldwide in different settings and to organize and manage the comprehensive rehabilitation programme for stroke survivors considering all impairments, comorbidities and complications, activity limitations and participation restrictions as well as personal and environmental factors.

Is physical rehabilitation effective for Wernicke-Korsakoff syndrome? A case report.

Wernicke-Korsakoff syndrome is a type of brain disorder caused by the lack of thiamine, most commonly because of chronic alcohol misuse. It consists of two separate conditions including Wernicke's encephalopathy and Korsakoff syndrome. Various levels of cognitive impairments are associated with the severity of the syndrome. Although the effectiveness of thiamine replacement in the early phases of the syndrome is proven, the efficacy of subsequent treatments, which mainly include rehabilitation protocols after the development of Korsakoff syndrome, is not clear. This is the first report showing the positive effects of physical rehabilitation in a 48-year-old male patient with Wernicke-Korsakoff syndrome.

The role of Interdisciplinary Teams in Physical and Rehabilitation Medicine.

The increasing complexity of healthcare provision and medical interventions requires collaboration between large numbers of health professionals. The nature of the interactions between team members determines whether the pattern of working is described as multi-, inter- or trans-disciplinary. Such team-working is an important part of the specialty of Physical and Rehabilitation Medicine. Grounded in group behaviour theory, team-working demonstrates that joint aims, trust and willingness to share knowledge, can improve patient outcomes, including mortality. The synthesis of individual skills and knowledge and working to common patient goals, has shown benefit in many conditions. This evidence base is perhaps best in stroke, but has been demonstrated in many other conditions, including acquired brain injury, back pain, mental health, cardiopulmonary conditions, chronic pain and hip fracture. There are also considerable benefits to staff and health organizations in terms of outcome and staff morale. This review paper examines the evidence for the benefit of such team-working and for the recommendations of team-working in rehabilitation services.

Kinaesthetic ability training improves unilateral neglect and functional outcome in patients with stroke: A randomized control trial.

OBJECTIVE: To investigate the effects of kinaesthetic ability training with the Kinesthetic Ability Trainer (KAT) on unilateral neglect and functional outcomes in stroke patients. STUDY DESIGN: An assessor-blinded, randomized controlled, clinical trial. METHODS: A total of 64 stroke patients with unilateral neglect (mean age 61 (standard deviation (SD) 12) years, 60.4% male, mean time since stroke 6.4 (SD 10.4) months, left hemiplegia 92.5%) were randomly assigned to a conventional rehabilitation programme (control group, n = 32) or KAT plus a conventional rehabilitation programme (KAT group, n = 32) for 4 weeks. Patients were assessed with the Behavioral Inattention Test (BIT) and Functional Independence Measure (FIM) before and after therapy. RESULTS: Both groups showed significant improvements in all subscales of the BIT (conventional and behavioural) (p < 0.001) and the FIM motor scale (p < 0.001) after therapy. Recovery from neglect was assessed, based on the BIT cut-off scores. The recovery rate for behavioural BIT was 40% in the KAT group and 17.9% in the control group (p = 0.07), whereas recovery rates according to the conventional BIT were 16% and 10.7% in the KAT and control groups, respectively. CONCLUSION: Kinaesthetic ability training provides clinically meaningful improvement in stroke patients with unilateral neglect. It may be useful as an adjunctive therapy for rehabilitation in these patients.
