Lower Limb Function

The need to measure and evaluate orthotics and prosthetics (O&P) practice has received growing recognition in the past several years. Reliable and valid self-report instruments are needed that can help facilities evaluate patient outcomes. The objective of this project was to develop a set of self-report instruments that assess functional status, quality of life, and satisfaction with devices and services that can be used in an orthotics and prosthetics clinic. Selecting items from a variety of existing instruments, the authors developed and revised four instruments that differentiate patients with varying levels of lower limb function, quality of life, and satisfaction with devices and services. Evidence of construct validity is provided by hierarchies of item difficulty that are consistent with clinical experience. For example, with the lower limb function instrument, running one block was much more difficult than walking indoors. The instruments demonstrate adequate internal consistency (0.88 for lower limb function, 0.88 for quality of life, 0.74 for service satisfaction, 0.78 for device satisfaction). The next steps in their research programme are to evaluate sensitivity and construct validity. The Orthotics and Prosthetics Users’ Survey (OPUS) is a promising self-report instrument which may, with further development, allow orthotic and prosthetic practitioners to evaluate the quality and effectiveness of their services as required by accreditation standards such as those of the American Board for Certification in Orthotics and Prosthetics that mandate quality assessment.

Introduction: We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer. Methods: This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach’s alpha and item-total correlation. Ceiling and floor effects were also investigated. Results: EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC- 26’s five domains met the acceptable reliability threshold based on Cronbach’s alpha. Ceiling effects were observed in four out of five domains. Conclusions: The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument’s five domains were not well-defined by their respective items. The original EPIC’s conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

Lower Limb Amputees

Background: In Turkey there is no amputee-specific instrument to measure health-related quality of life in lower limb amputees. Objectives: To evaluate the validity and reliability of a Turkish version of the Trinity Amputation and Prosthesis Experience Scales (TAPES). Study design: Outcome study to determine test–retest reliability and construct validity of the adapted Turkish version of the TAPES. Methods: After translation/retranslation of the TAPES, the Turkish version of the TAPES was applied to 47 amputees. A quality of life evaluation (Nottingham Health Profile), a satisfaction evaluation (Satisfaction with Prosthesis), and a functional assessment tool (Amputee Mobility Predictor) were also performed and analysed. Results: On the basis of retesting, the Turkish version of the TAPES was observed to be reliable. The first domain of the Turkish version, which includes psychosocial adjustment, activity restriction and satisfaction with the prosthesis, was found to be valid. However, the validity of the second domain could not be analysed. Conclusions: The Turkish version of the multidimensional TAPES survey is valid and reliable in Turkish unilateral lower limb amputees and may be used in clinical situations to assess the needs of amputees. Clinical relevance The Turkish version of the TAPES quality-of-life measurement tool for amputees is a valid instrument for assessing the effectiveness of rehabilitation and clinical applications.

Lower Limb Amputees

Background:Most amputees live with their prostheses for a long time. Therefore, quality of life is an important outcome for lower limb amputees.Objective:To translate the Prosthesis Evaluation Questionnaire (PEQ) and evaluate psychometric properties.Study Design:Methodological research.Methods:Lower limb amputees responded to electronic versions of the PEQ and SF-36v2 at baseline (n=64), after two weeks (n=51), and after 12 weeks (n=50). Reliability was assessed using Cronbach’s alpha and intraclass correlation coefficient (ICC) analyses of the baseline and two weeks test-retest data. Estimates for standard error of measurement (SEM) were calculated based on reliability estimates. Construct validity was evaluated by testing using hypotheses testing.Results:Reliability estimates (ICC/Cronbach’s alpha) for the nine subscales were: Social Burden (0.85/0.76), Appearance (0.85/0.72), Residual Limb Health (0.80/0.69), Well-Being (0.78/0.90), Utility (0.76/0.89), Frustration (0.74/0.90), Perceived Response (0.62/0.80), Ambulation (0.61/0.94), Sounds (0.51/0.65). Construct validity was supported in three out of four subscales evaluated.Conclusions:The subscales Social Burden, Appearance, Well-Being, Utility and Frustration had consistent high reliability, supporting their use in assessing the prosthesis related quality of life in lower limb amputees. Results were mixed on three other scales (Residual Limb Health, Perceived Response, and Ambulation), while one scale, Sounds, had consistent low reliability.Clinical relevanceFor the first time a patient reported disease specific quality of life measure for lower limb amputees is available in Danish. Health care providers can now identify patients with reduced quality of life and measure treatment and rehabilitation effects over time.

Validity And Reliability

Multiple sclerosis (MS) has important effects on quality of life but it is unknown how cognitive impairment affects the ability to assess or report this. O ur objective was to determine whether cognitive impairment negatively affects the construct validity and the reliability of the Multiple Sclerosis Q uality of Life Inventory (MSQLI). A neuropsychological test batter y and the Multiple Sclerosis Functional C omposite (MSFC) were administered to a sample of 136 patients referred for cognitive testing by their neurologists. A ge, sex, educatio n and ethnicity-adjusted T scores were calculated for each cognitive variable. C ognitive impairment was defined as any T score less than the fifth percentile. The MSQ LI was administered prior to neuropsychological testing and readministered one to four weeks later. C orrelations between the MSFC and the SF-36 were determined and compared between the cognitively impaired and unimpaired groups as the main test of construct validity. Test -retest and internal consistency reliability of each of the scales were compared for the impaired and unimpaired groups. Seventy-six (56%) patients were cognitively impaired. C onstruct validity and internal consistency reliability did not differ between the cognitively impaired and unimpaired groups. Test -retest reliability was lower for the bladder and vision scales in the impaired group, but remained acceptable for the bladder scale (r >0.7). C ognitive impairment, a common MS manifestation, does not appear to reduce the reliability or validity of the MSQ LI as a patient self-report measure of health status and quality of life.

Background The Lymphoedema Quality-of-Life Questionnaire is a validated disease-specific instrument to measure the impact of lymphoedema on patients’ lives. In this study, we tested its psychometric properties and validated the use of the questionnaire in its Dutch translation. Methods We obtained the answers to a standardised questionnaire, including Lymphoedema Quality-of-Life Questionnaire and Short-Form (36) Health Survey, twice at an interval of 2 weeks in 60 patients with lower limb lymphoedema. Feasibility was tested on the basis of missing responses and response distribution. Structure was studied using factor analysis. The reliability of the Lymphoedema Quality-of-Life Questionnaire was assessed using Crohnbach’s α and test-retest reliability. Construct validity was tested by correlating Lymphoedema Quality-of-Life Questionnaire scores with the Short-Form (36) Health Survey scores. Results The response rate was 88.2%. One of the 22 items missed >10% of responses; another showed a borderline ceiling effect. Internal consistency was good and test-retest reliability was excellent. The Lymphoedema Quality-of-Life Questionnaire correlated well with the physical component of the Short-Form (36) Health Survey and moderately with the mental component, suggesting that its construct validity was good. Conclusion The Dutch Lymphoedema Quality-of-Life Questionnaire can be used for health-related quality-of-life research in lower limb lymphoedema patients.

Abstract Purpose The evaluation of measurement properties such as reliability, measurement error, construct validity, and responsiveness provides information on the quality of the scale as a whole, rather than on an item level. We aimed to synthesize the measurement properties referring to reliability, measurement error, construct validity, and responsiveness of the Victorian Institute of Sport Assessment questionnaires (Achilles tendon—VISA-A, greater trochanteric pain syndrome—VISA-G, proximal hamstring tendinopathy—VISA-H, patellar tendon—VISA-P). Methods A systematic review was conducted according to Consensus-based Standards for the Selection of Health Measurement Instruments methodology (COSMIN). PubMed, Cochrane, CINAHL, EMBASE, Web of Science, SportsDiscus, grey literature, and reference lists were searched. Studies assessing the measurement properties concerning reliability, validity, and responsiveness of the VISA questionnaires in patients with lower limb tendinopathies were included. Two reviewers assessed the methodological quality of studies assessing reliability, validity, and responsiveness using the COSMIN guidelines and the evidence for these measurement properties. A modified Grading of Recommendations Assessment Development and Evaluation (GRADE) approach was applied to the evidence synthesis. Results There is moderate-quality evidence for sufficient VISA-A, VISA-G, and VISA-P reliability. There is moderate-quality evidence for sufficient VISA-G and VISA-P measurement error, and high-quality evidence for sufficient construct validity for all the VISA questionnaires. Furthermore, high-quality evidence exists with regard to VISA-A for sufficient responsiveness in patients with insertional Achilles tendinopathy following conservative interventions. Conclusions Sufficient reliability, measurement error, construct validity and responsiveness were found for the VISA questionnaires with variable quality of evidence except for VISA-A which displayed insufficient measurement error. Level of evidence IV. Registration details Prospero (CRD42018107671); PROSPERO reference—CRD42019126595.
