Purpose: Work participation of persons with spinal cord injury (SCI) is lower compared to the overall Dutch population, with determinants largely unknown.

Aim: To identify the determinants of sustainable work participation for persons with SCI.

Methods: A cross-sectional multicenter study was conducted in eight Dutch rehabilitation centers.

Objective: To assess the test-retest reliability and agreement of the work ability index-single item (WAS) in persons with a physical disability.

Design: Test-retest study, with a 2-4 week interval. Test-retest reliability was computed using the intraclass correlation coefficient (ICC).

In the field of soft robotics, knowledge of material science is becoming more and more important. However, many researchers have a background in only one of both domains. To aid the understanding of the other domain, this tutorial describes the complete process from polymer synthesis over fabrication to testing of a soft finger.

Humins waste valorization is considered to be an essential pathway to improve the economic viability of many biorefinery processes and further promote their circularity by avoiding waste formation. In this research, the incorporation of humins in a Diels-Alder (DA) polymer network based on furan-maleimide thermoreversible crosslinks was studied. A considerable enhancement of the healing efficiency was observed by just healing for 1 h at 60 °C at the expense of a reduction of the material mechanical properties, while the unfilled material showed no healing under the same conditions.

Study Design: Mixed methods.

Objectives: The aim of our study was to investigate the content validity of the Work Rehabilitation Questionnaire (WORQ) for use in persons with post-acute and chronic spinal cord injury (SCI).

Setting: A university-based Rehabilitation Center in The Netherlands.

Soft robots are, due to their softness, inherently safe and adapt well to unstructured environments. However, they are prone to various damage types. Self-healing polymers address this vulnerability.

Objective: Self-efficacy (SE) is an important determinant for the psychological adjustment of people with spinal cord injury (SCI). However, little is known about the course of SE during inpatient rehabilitation up to 1 year after discharge. The aim of this study was to determine latent trajectory classes of SE, depressive mood, and anxiety in people with SCI, as well as the interrelationships between these trajectories.

Purpose The Work Rehabilitation Questionnaire (WORQ) is a self-report vocational rehabilitation assessment. A comprehensive (WORQ-FULL) and a brief version (WORQ-BRIEF) are available. The purpose of this study was to investigate measurement properties of both versions in persons with physical disabilities.

Sensing pressure at the physical interface between the robot and the human has important implications for wearable robots. On the one hand, monitoring pressure distribution can give valuable benefits on the aspects of comfortability and safety of such devices. Additionally, on the other hand, they can be used as a rich sensory input to high level interaction controllers.

Objectives: To identify intra- and interpersonal sociodemographic, injury-related, and psychological variables measured at admission of inpatient rehabilitation that predict psychological distress among dyads of individuals with spinal cord injury (SCI) or acquired brain injury (ABI) and their significant others (ie, individuals close to the individual with a disability, mostly family members) 6 months after discharge. Differences in predictors were investigated for persons with SCI or ABI and their significant others and were compared between diagnoses.

Design: Prospective longitudinal study.

The field of self-healing soft robots was initiated a few years ago. A healing ability can be integrated in soft robots by manufacturing their soft membranes out of synthetic self-healing polymers, more specifically elastomeric Diels-Alder (DA) networks. As such they can recover completely from macroscopic damage, including scratches, cuts, and ruptures.

Employment rates among people with spinal cord injury or spinal cord disease (SCI/D) show considerable variation across countries. One factor to explain this variation is differences in vocational rehabilitation (VR) systems. International comparative studies on VR however are nonexistent.

In the Dutch International Spinal Cord Injury (SCI) Data Sets project, we translated all International SCI Data Sets available in 2012 and created a Dutch SCI Database (NDD). To describe the number of included patients and completeness of the NDD, and to use the NDD to provide a profile of people with traumatic SCI (T-SCI) and non-traumatic SCI (NT-SCI) in the Netherlands. The NDD includes patients admitted for their first inpatient rehabilitation after onset of SCI to 1 of the 8 rehabilitation centers with a specialty in SCI rehabilitation in the Netherlands.

Study Design: Multicentre, cross-sectional study.

Objectives: To describe the relationships between the presence of (different types of) pain and participation in paid work in people with long-standing spinal cord injury (SCI). Furthermore, the associations of pain-related work limitations, age, gender, relationship, education, lesion level, and time since injury (TSI) with work participation (WP) were investigated.
