Foot Orthosis

Background: Comfort of an orthosis is an important characteristic that is likely to dictate use of and satisfaction with a device. However, instruments to assess only orthosis user comfort do not exist. The Prosthetic Socket Fit Comfort Score, developed previously for prosthesis users, may be adapted to serve this purpose. Objectives: This study’s purpose was to assess the validity and reliability of the Orthosis Comfort Score, a self-report instrument adapted from the Prosthetic Socket Fit Comfort Score. Study design: This is a prospective, observational study designed to establish initial evidence of validity and reliability for an outcome measure that assesses comfort. Methods: Ankle foot orthosis users completed the Orthosis Comfort Score and two validated patient satisfaction questionnaires. An orthotist documented an assessment of fit. Post-visit Orthosis Comfort Scores were documented after the appointment and 2–4 weeks later. Orthosis Comfort Scores were compared to the patient satisfaction questionnaires, assessment of fit and orthosis use (hours per week). Results: There were 46 study participants. Orthosis Comfort Scores had a moderate positive correlation with their orthotist’s assessment of fit, very strong positive correlations with patient satisfaction questionnaires and fair positive correlation with orthosis use (all correlations p < 0.05). Conclusion: This study demonstrates initial evidence for the validity and reliability of the Orthosis Comfort Score in ankle foot orthosis users. Clinical relevance The Orthosis Comfort Score is a simple patient-reported outcome measure that can be readily incorporated into clinical practice or research study to obtain a rapid assessment of comfort. It can be used to facilitate communication about device fit, evaluate comfort over time and/or assess changes in comfort with a new device.

Foot Orthosis

Shape memory alloys (SMAs) provide compact and effective actuation for a variety of mechanical systems. In this work, the distinguished superelastic behavior of these materials is utilized to develop a passive ankle foot orthosis to address the drop foot disability. Design, modeling, and experimental evaluation of an SMA orthosis employed in an ankle foot orthosis (AFO) are presented in this paper. To evaluate the improvements achieved with this new device, a prototype is fabricated and motion analysis is performed on a drop foot patient. Results are presented to demonstrate the performance of the proposed orthosis.

This study investigated aspects of the validity and reliability of the 30-item Disabilities of the Arm, Shoulder and Hand patient-reported outcome measure (DASH) and its relationship with the shorter 11-item QuickDASH in patients with Dupuytren’s disease. Seven hundred and fifty-nine DASH questionnaires were studied, covering pre- and postoperative patients undergoing different treatments for Dupuytren’s disease. Items related to pain rose early after treatment before returning to baseline, suggesting that studying pain is relevant during postoperative recovery. Across all 759 sets of responses, the QuickDASH agreed closely with the DASH. In exploratory factor analysis, the DASH was not unidimensional, questioning the validity of the DASH summary score in Dupuytren’s disease. Further validation of existing PROMs for use in Dupuytren’s disease is needed. These data suggest that pain is a relevant symptom to study during postoperative recovery following treatment for Dupuytren’s disease. Level of evidence: III.

Foot Orthosis

Background: Excessive first ray mobility has been implicated as the cause of many forefoot abnormalities. The association between hypermobility and forefoot pathology is controversial, and this is largely related to the difficulty in quantifying first ray motion. Manual examinations have been shown to be unreliable. Klaue et al. developed a device consisting of a modified ankle-foot orthosis with an attached micrometer to objectively measure first ray mobility. The purpose of this study was to evaluate the validity and reliability of this device. Methods: Sixteen fresh-frozen, below-knee amputation specimens with hallux valgus were used for the study. The study was divided into two parts. Part I was an analysis of the validity of the Klaue device; first ray dorsal displacement was measured on lateral radiographs following manual manipulation, and values were statistically compared to the Klaue device measurements. Part II of the study was an evaluation of intraobserver and interobserver agreement. Two clinicians used the Klaue device on each of the cadaver limbs, and values of first ray sagittal mobility were recorded and compared. Results: The mean value of first ray mobility measured with the Klaue device was 7.5 mm and the average displacement measured from the lateral radiographs was 7.4 mm. Paired t-testing showed no significant difference between the Klaue and radiographic measurements ( p = 0.83). The mean first ray mobility by examiners 1 and 2 with the Klaue device were identical (10.5 mm), and statistical analysis showed no significant interobserver or intraobserver differences. Conclusions: The results confirm the validity of the Klaue device and limited variability of measurements between experienced users.

Objectives: Katakori is a Japanese term for non-specific symptoms including discomfort or dull pain caused by muscle stiffness around the neck through the shoulders and is one of the most frequently reported symptoms in Japan. However, there has been no standardized patient-reported outcome measure to evaluate Katakori severity. This study aimed to investigate the reporting level on validity and reliability of patient-reported outcome measures of Katakori severity. Method: A systematic search in ICHUSHI, MEDLINE, EMBASE and PubMed was undertaken from inception to April 2017 without language limitations. Two authors independently undertook screening by inspecting the title and abstract. Inclusion criteria were as follows: (1) participants with Katakori symptoms, (2) reporting reliability or validity of questionnaire evaluating Katakori severity and (3) published journal articles. Studies that either of the authors retained through the screening process were inspected with full text by the two authors independently to examine eligibility of the study. Any disagreement on eligibility after full-text inspection was resolved by discussion between them. Methodological quality was rated with the COnsensus-based Standards for the selection of health Measurement INstruments checklist. Subsequently, the evidence level of each measurement property was assessed for each questionnaire. The two authors extracted data independently. Any disagreement was resolved by discussion between them. Results: Five questionnaires were identified in five studies. The Shoulder Pain and Disability Index and Scale for Measuring Felt Shoulder Stiffness had the highest level of methodological quality. However, excellent measurement properties were found in only two out of nine criteria. Furthermore, in particular, content validity was not investigated in any measure. Conclusion: There is preliminary evidence for the reliability and validity of the Shoulder Pain and Disability Index and Scale for Measuring Felt Shoulder Stiffness; however, much further research is required. Identifying or developing a patient-reported outcome measure with content validity would be a future research agenda.

Objective To compare the energy efficiency of gait with knee-ankle-foot orthosis (KAFO) and robot-assisted gait and to develop a usability questionnaire to evaluate the satisfaction of walking devices in paraplegic patients with spinal cord injuries.Methods Thirteen patients with complete paraplegia participated and 10 completed the evaluation. They were trained to walk with KAFO (KAFO-gait) or a ReWalk robot (ReWalk-gait) for 4 weeks (20 sessions). After a 2-week wash-out period, they switched walking devices and underwent 4 additional weeks of training. Two evaluations were performed (after 2 and 4 weeks) following the training periods for each walking device, using the 6-minute walking test (6MWT) and 30-minute walking test (30MWT). The spatiotemporal variables (walking distance, velocity, and cadence) and energy expenditure (heart rate, maximal heart rate, the physiologic cost index, oxygen consumption, metabolic equivalents, and energy efficiency) were evaluated duringthe 6MWT and 30MWT. A usability evaluation questionnaire for walking devices was developed based on the International Organization for Standardization/International Electrotechnical Commission guidelines through expert consultation.Results The ReWalk-gait presented significant advantages in energy efficiency compared to KAFO-gait in the 6MWT and 30MWT; however, there were no differences in walking distance or speed in the 30MWT between ReWalk-gait and KAFOgait. The usability test demonstrated that ReWalk-gait was not superior to KAFO-gait in terms of safety, efficacy, efficiency, or patient satisfaction.Conclusion The robot (ReWalk) enabled patients with paraplegia to walk with lower energy consumption compared to KAFO, but the ReWalk-gait was not superior to KAFO-gaitin terms of patient satisfaction.

This study evaluated the psychometric properties of a self-report scale for assessing perceived driver competence, labeled the Self-Efficacy Scale for Driver Competence (SSDC), using item response theory analyses. Two samples of Swedish driving-license examinees (n = 795; n = 714) completed two versions of the SSDC that were parallel in content. Prior work, using classical test theory analyses, has provided support for the validity and reliability of scores from the SSDC. This study investigated the measurement precision, item hierarchy, and differential functioning for males and females of the items in the SSDC as well as how the rating scale functions. The results confirmed the previous findings; that the SSDC demonstrates sound psychometric properties. In addition, the findings showed that measurement precision could be increased by adding items that tap higher self-efficacy levels. Moreover, the rating scale can be improved by reducing the number of categories or by providing each category with a label.
