Development and refinement of outcome measures and users' satisfaction in physical medicine and rehabilitation
No full textIn recent years, the interest in outcome measures has grown in the effort to improve quality of care and customer satisfaction. This thesis provides an overview of topics related to development and refinement of outcome measures and users' satisfaction measurement in Physical and Rehabilitation Medicine. The eight chapters - represented by original articles - are examples of the application of contemporary measurement approaches to some instruments commonly used in rehabilitation. These studies illustrate advances in measurement theory and methods that allow outcome indicators to be measured more accurately, including Rasch analysis. Their utility for researchers and clinicians are discussed.
Chapter I focuses on the interpretation of the change scores of two common outcome measures for the upper limb: the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and its short version (QuickDASH). In this work the minimal clinically important difference (MCID) was calculated by a triangulation of distribution and anchor-based approaches for these two questionnaires. The MCID thresholds represents the smallest improvement considered worthwhile by a patient, and thus increase the interpretability of score changes at individual level observed in the clinical setting. Assessing patient progress is an integral part of clinical practice, and meaningful threshold change values of outcome tools are essential for decision making regarding a patient‟s status and to facilitate the communication of results in a concise and comprehensible fashion.
Among the different tools used for the assessment of musculoskeletal disorders of the lower limb, the Foot and Ankle Ability Measure (FAAM) showed good psychometrics properties. However, it has not yet been made a translation into Italian. Chapter II shows how to conduct a translation and cross-cultural adaptation of a questionnaire according to the international guidelines for the forward/backward translation. The activities od daily living (ADL) module of the Italian FAAM (FAAM-I/ADL) was translated and then validated with the classical test theory, taking into consideration internal consistency, reproducibility, sensitivity to change and validity.
Chapter III presents an example of the test-retest reliability analysis and normative data collection of the the Functional Dexterity Test (FDT). Among the available tests for fine finger dexterity, it has been indicated as a valid instrument to measure outcome in different conditions. FDT scores were collected on a large sample of subjects (N=698) stratified by sex and
age. These data could be used, for example, to improve the diagnostic capacity of this test.
Chapters IV, V and VI report the complex process of validation through the Rasch analysis. In particular, the aim of Chapter IV and V was to perform the translation and cross-cultural adaptation into Italian and Arabic of the recently revised version of the Client Satisfaction with Device (CSD) module of the Orthotics and Prosthetics Users' Survey (OPUS), and then analyze its psychometric properties using factor and Rasch analyses. The need for validated versions of this instrument into Italian and Arabic is documented by the fact that information on patient satisfaction with orthosis (PSwO) is crucial for verifying and enhancing orthotic quality, for clinical decision making, and for improving patient's quality of life. The aim of the study included in Chapter VI was to perform a comprehensive analysis of the psychometric properties and dimensionality of the Italian version of the Upper Limb Functional Index (ULFI) using both Classical Test Theory and Rasch analysis.
The last two chapters - VII and VIII - are systematic reviews of the literature. Chapter VII reports a literature search aimed at identifying which validated questionnaires are used to investigate PSwO in limb orthotics, and analyse their main fields of clinical application, the orthosis-related features analysed by the questionnaires, and the strength of their psychometric properties. Chapter VIII covers the topic of post-surgical scar assessment in rehabilitation. The study is a systematic review that provides a critical appraisal of the most used and clinimetrically sound outcome measures currently available for this topic

Clinimetric properties and clinical utility in rehabilitation of postsurgical scar rating scales: a systematic review
No full textThe aim of this study was to review and critically assess the most used and clinimetrically sound outcome measures currently available for postsurgical scar assessment in rehabilitation. We performed a systematic review of the Medline and Embase databases to June 2015. All published peer-reviewed studies referring to the development, validation, or clinical use of scales or questionnaires in patients with linear scars were screened. Of 922 articles initially identified in the literature search, 48 full-text articles were retrieved for assessment. Of these, 16 fulfilled the inclusion criteria for data collection. Data were collected pertaining to instrument item domains, validity, reliability, and Rasch analysis. The eight outcome measures identified were as follows: Vancouver Scar Scale, Dermatology Life Quality Index, Manchester Scar Scale, Patient and Observer Scar Assessment Scale, Bock Quality of Life (Bock QoL) questionnaire, Stony Brook Scar Evaluation Scale, Patient-Reported Impact of Scars Measure, and Patient Scar Assessment Questionnaire. Scales were examined for their clinimetric properties, and recommendations for their clinical or research use and selection were made. There is currently no absolute gold standard to be used in rehabilitation for the assessment of postsurgical scars, although the Patient and Observer Scar Assessment Scale and the Patient-Reported Impact of Scars Measure emerged as the most robust scales
Preliminary validation of a new questionnaire to assess user satisfaction with orthotic devices
No full textRasch analysis of the Italian Lower Extremity Functional Scale: insights on dimensionality and suggestions for an improved 15-item version
No full textObjective: To investigate dimensionality and the measurement properties of the Italian Lower Extremity Functional Scale using both classical test theory and Rasch analysis methods, and to provide insights for an improved version of the questionnaire. Design: Rasch analysis of individual patient data. Setting: Rehabilitation centre. Participants: A total of 135 patients with musculoskeletal diseases of the lower limb. Results: Patients were assessed with the Lower Extremity Functional Scale before and after the rehabilitation. Rasch analysis showed some problems related to rating scale category functioning, items fit, and items redundancy. After an iterative process, which resulted in the reduction of rating scale categories from 5 to 4, and in the deletion of 5 items, the psychometric properties of the Italian Lower Extremity Functional Scale improved. The retained 15 items with a 4-level response format fitted the Rasch model (internal construct validity), and demonstrated unidimensionality and good reliability indices (person-separation reliability 0.92; Cronbach’s alpha 0.94). Then, the analysis showed differential item functioning for six of the retained items. The sensitivity to change of the Italian 15-item Lower Extremity Functional Scale was nearly equal to the one of the original version (effect size: 0.93 and 0.98; standardized response mean: 1.20 and 1.28, respectively for the 15-item and 20-item versions). Conclusion: The Italian Lower Extremity Functional Scale had unsatisfactory measurement properties. However, removing five items and simplifying the scoring from 5 to 4 levels resulted in a more valid measure with good reliability and sensitivity to change
The EdUReP approach plus manual therapy for the management of insertional Achilles tendinopathy
No full textInsertional Achilles tendinopathy (IAT) is a challenging overuse disorder. The aim of this case report was to study the feasibility of a comprehensive rehabilitative approach according to the Education, Unloading, Reloading, and Prevention (EdUReP) framework combined with Instrument-Augmented Soft Tissue Mobilization (I-ASTM). An active 51-year-old man patient with chronic IAT was studied. Clinical assessment battery was composed by visual analogue scale for pain during the Achilles tendon palpation test, passive straight leg raise test, single leg hop test, Patient-Specific Functional Scale, and Foot and Ankle Ability Measure. The patient was treated over a 8 weeks period using the EdUReP guidelines plus 8 sessions of I-ASTM, applied with a solid instrument to the Achilles tendon and to the muscle fibrotic areas previously identified during evaluation. Clinically significant improvements were observed in all outcome measures, and a resume of patient's usual sports activities without pain or limitations was possible after treatment. Results lasted over a 6-month follow-up. To the best of our knowledge, this is the first study applying a comprehensive approach based on accurate physical assessment, and using the EdUReP theoretical model. The combination of the EdUReP model and manual therapy was effective in resolving the patient's symptoms and restore his usual sport activities. While these results cannot be generalized, the present findings could provide a valuable foundation for future researches
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A systematic review of questionnaires to assess patient satisfaction with limb orthoses
No full textBackground: Assessment of patient satisfaction with orthosis is a key point for clinical practice and research, requiring questionnaires with robust psychometric properties. Objectives: To identify which validated questionnaires are used to investigate patient satisfaction with orthosis in limb orthotics and to analyse (1) their main fields of clinical application, (2) the orthosis-related features analysed by the questionnaires and (3) the strength of their psychometric properties. Study design: Systematic review. Methods: A literature search using MEDLINE (PubMed), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus databases for original articles published within the last 20 years was performed. Results: A total of 106 papers pertaining to various clinical fields were selected. The main features of patient satisfaction with orthosis analysed were as follows: aesthetic, ease in donning and doffing the device, time of orthotic use and comfort. Conclusion: Of the questionnaires used to investigate patient satisfaction with orthosis, only four are adequately validated for this purpose: two for generic orthotic use (Quebec User Evaluation of Satisfaction with assistive Technology 2.0 and Client Satisfaction with Device of Orthotics and Prosthetic Users' Survey) and two for specific application with orthopaedic shoes (Questionnaire for the Usability Evaluation of orthopaedic shoes and Monitor Orthopaedic Shoes). Further development, refinement and validation of outcome measures in this field are warranted. Clinical relevance Given the importance of analysing patient satisfaction with orthosis (PSwO), appropriate instruments to assess outcome are needed. This article reviews the currently available instruments and reflects on how future studies could be focused on the development, refinement and validation of outcome measures in this field
