Results of a 12-Month Randomized Controlled Trial Testing the Efficacy of the Diabetes Prevention Program Group Lifestyle Balance (DPP-GLB) for People Post Stroke (GLB-CVA)
Background: Experience of stroke is associated with an increased risk for diabetes and metabolic syndrome, yet few interventions exist that have been tailored to the population’s unique needs. Purpose: To examine adherence and efficacy of the Diabetes Prevention Program Group Lifestyle Balance program (DPP-GLB) modified for individuals post stroke (GLB-CVA) using a randomized controlled trial. Methods: Adults (18–85 years of age), >12 months post stroke, and body mass index ≥25 kg/m2 were included in this study. Sixty-five individuals were assigned to either the GLB-CVA intervention or a 6-month wait-list control. Participants completed the 12-month GLB-CVA intervention, with attendance and assessment of weight, anthropometric, biomarker, functional, and patient reported outcome data collected at baseline, 3, 6, and 12 months. Results: High attendance (90%) and dietary and activity tracking (71%) suggest high adherence to the 12-month GLB-CVA. Six-month randomized controlled trial data indicate significant weight loss (p = .005) in the GLB-CVA group (7.4 ± 13.6 lbs, 3.65%) compared with the wait-list control (0.1 ± 10.1 lbs, 0%), and improvements in arm circumference (p = .04), high-density lipoprotein (HDL) cholesterol (p = .028), 8-year diabetes risk (p = .011), and pain interference (p < .001). Combined 12-month data showed participants lost 10.1 ± 16.8 lbs (4.88%) and improved waist circumference (p = .001), HbA1c (3.6%), diastolic blood pressure (p < .001), pain (p = .001), social participation (p = .025), and eating practices (p = .01) and habits (p < .001). Conclusions: Engagement in the GLB-CVA can result in weight loss and improved health for individuals who are overweight or obese following stroke. Future efforts should examine effectiveness in real-world settings and focus on knowledge translation efforts.

Utilization of overground exoskeleton gait training during inpatient rehabilitation: a descriptive analysis
Background: Overground exoskeleton gait training (OEGT) after neurological injury is safe, feasible, and may yield positive outcomes. However, no recommendations exist for initiation, progression, or termination of OEGT. This retrospective study highlights the clinical use and decision-making of OEGT within the physical therapy plan of care for patients after neurological injury during inpatient rehabilitation. Methods: The records of patients admitted to inpatient rehabilitation after stroke, spinal cord injury, or traumatic brain injury who participated in at least one OEGT session were retrospectively reviewed. Session details were analyzed to illustrate progress and included: “up” time, “walk” time, step count, device assistance required for limb swing, and therapist-determined settings. Surveys were completed by therapists responsible for OEGT sessions to illuminate clinical decision-making. Results: On average, patients demonstrated progressive tolerance for OEGT over successive sessions as shown by increasing time upright and walking, step count, and decreased assistance required by the exoskeleton. Therapists place preference on using OEGT with patients with more functional dependency and assess feedback from the patient and device to determine when to change settings. OEGT is terminated when other gait methods yield higher step repetitions or intensities, or to prepare for discharge. Conclusion: Our descriptive retrospective data suggests that patients after neurological injury may benefit from OEGT during inpatient rehabilitation. As no guidelines exist, therapists’ clinical decisions are currently based on a combination of knowledge of motor recovery and experience. Future efforts should aim to develop evidence-based recommendations to facilitate functional recovery after neurological injury by leveraging OEGT.

Effectiveness and feasibility of the workout on wheels internet intervention (WOWii) for individuals with spinal cord injury: a randomized controlled trial
Study design Randomized-controlled trial (RCT) with immediate intervention (IMM) and wait-list control (WLC) groups; WLC participants received the intervention during delivery to subsequent cohorts. Objectives Investigate the effectiveness and feasibility of a virtually-delivered exercise intervention. Setting Home and community. Methods A total of 168 middle-aged (49.6 [12.3] years old) men (57%) and women (43%) who lived an average 15.5 (12.3) years with spinal cord injury (SCI) participated. The 16-week program provides users (a) website access with exercise information, resources, and 16 skill-building modules; (b) virtual 60-minute, group-based weekly meetings; and (c) a starter package of exercise equipment. Primary outcomes included subjective physical activity (IPAQ) and objective exercise (Polar A300 wrist-based activity monitor and H7 heart rate strap). Secondary outcomes included fitness indices during a maximal arm crank test, plus self-reported exercise barriers, exercise self-efficacy, and goal-directed thinking. Results RCT results indicate significant between group differences in participants’ self-reported weekly time spent in vigorous-intensity PA and goal directed thinking but not for fitness changes. Data combined for IMM and WLC participants from Polar monitoring show participants performed 150 min per week of aerobic exercise plus reported significantly greater time spent in moderate-PA, vigorous-PA, self-efficacy for exercise and nutrition, goal directed thinking, and exercise barriers. Oxygen uptake (V̇O2 peak) and power output (watts max) were the only physiologic measures to demonstrate significant change, with a moderate effect size. Conclusion This virtually-delivered program offers a promising approach to increase exercise among those with SCI and may help participants perceive fewer motivational barriers and greater self-efficacy.

Feasibility of an Internet-Based Intervention to Promote Exercise for People With Spinal Cord Injury: Observational Pilot Study
Background: People with spinal cord injury (SCI) are less likely to be physically active and have higher chronic disease risk than those in the general population due to physical and metabolic changes that occur postinjury. Few studies have investigated approaches to promote increased physical activity (PA) for people with SCI despite evidence that they face unique barriers, including lack of accessible transportation and exercise equipment. To address these obstacles, we adapted an evidence-based phone-delivered intervention that promoted increased PA among people with SCI into a web-based platform, titled the Workout on Wheels internet intervention (WOWii). The adapted program provides participants with weekly skill-building information and activities, basic exercise equipment, and ongoing support through weekly group videoconferencing. Objective: This pilot study was conducted to assess the feasibility of using a web-based and virtual format to deliver the WOWii program in a randomized controlled trial. Methods: We assessed the feasibility of the web-based program by delivering an abbreviated, 4-week version to 10 participants with SCI. Rates of weekly videoconference attendance, activity completion, and exercise activity as tracked by an arm-based activity monitor were recorded for all participants. Results: Participants averaged 3.3 of 4 (83%) weekly group videoconferences attended, 3.4 of 4 (85%) web-based module activities completed, and 2.3 of 4 (58%) weeks of using the arm-based activity monitor. The majority of the sample (9/10, 90%) synced their arm-based PA monitor at least once, and overall engagement as an average of each component across the 4 weeks was 75%. Conclusions: The intervention had sufficiently high levels of engagement to be used in a full randomized controlled trial to test its effectiveness in improving levels of PA among people with SCI. The knowledge we gained from this pilot study informed improvements that were made in the full randomized controlled trial.

Electronic patient portal utilization by neurology patients and association with outcomes
Existing literature on electronic patient portals demonstrates mixed findings for portal user demographic patterns and relationships between portal usage and clinical outcomes. This study sought to determine characteristics of portal users specific to a neurology patient population and examine whether usage predicted decreased clinic visits and risk of hospitalization. A cross-sectional analysis on 13,483 patients seen at a tertiary neurology outpatient clinic over a 1-year period found significant associations between demographics, and interactions between age, sex, and race. Black and Hispanic patients were less likely to be portal users. While females had higher odds of portal usage overall, their probability decreased with increasing age. Portal users had higher rates of clinic utilization but no difference in hospitalization risk. These results highlight demographics that may need strategic targeting to increase portal uptake and the need for other interventions for populations more likely to experience health events resulting in hospitalization.
