Objectives: To compare the effectiveness of two different interventions that promote physical activity in individuals with traumatic spinal cord injury (SCI) and determine the effect of relapse prevention.

Methods: A sequential, multiple assignment, randomized trial was conducted at a universally designed community-based exercise facility. Participants were individuals with traumatic SCI, >3 months post injury, levels C5 to T12, age ≥18 years ( = 79).

Objective: Exploratory application of the Rasch Measurement (RM) Model for evidence for reproducibility, conceptual/content validity, and structural validity of the Moorong Self-Efficacy Scale (MSES).

Study Design: Secondary RM analysis of data collected in a randomized controlled trial comparing two exercise interventions for persons living with spinal cord injury (SCI).

Setting: Community-dwelling persons living with SCI enrolled in an exercise study.

The presence of di-/multi-meric forms of soluble target in biological samples can interfere in anti-drug antibody (ADA) assays, leading to increased background values and potentially false positivity. The authors investigated the use of the high ionic strength dissociation assay (HISDA) to reduce target interference in two different ADA assays. Interference caused by homodimeric FAP was successfully eliminated to enable cut point determination after applying HISDA.

Objective: To demonstrate feasibility of generating predictive short-term individual trajectory recovery models after acute stroke by extracting clinical data from an electronic medical record (EMR) system.

Design: Single-group retrospective patient cohort design.

Setting: Stroke rehabilitation unit at an independent inpatient rehabilitation facility (IRF).
