Background: Stroke is one of the leading causes of death and the main cause of long-term disability in the United States. The significant risk factors of stroke among Hispanics are well-documented. The majority of stroke survivors return home following a stroke and are cared for by family caregivers. Due to the abrupt nature of strokes, caregivers experience unexpected changes and demands that oftentimes lead to caregiver burden and depression. Given the significant risk factors for stroke in Hispanics and the influence of culture in family norms and family management, we developed a telephone and online problem-solving intervention for Spanish-speaking stroke caregivers. This study tests the impact of a telephone and online problem-solving intervention for Spanish-speaking stroke caregivers on caregiver outcomes. Methods: The design is a two-arm parallel randomized clinical trial with repeated measures. We will enroll 290 caregivers from 3 Veterans Affairs (VA) medical centers. Participants randomized into the intervention arm receive a problem-solving intervention that uses telephone and online education and care management tools on the previously developed and nationally available RESCUE en Español Caregiver website. In the usual care group, participants receive the information and/or support caregivers of veterans with stroke normally receive through existing VA resources (e.g., stroke-related information and support). The primary outcome is change in caregiver's depressive symptoms at 1- and 12-weeks post-intervention. Secondary outcomes include changes in stroke caregivers' burden, self-efficacy, problem-solving, and health-related quality of life (HRQOL) and veterans' functional abilities. We will also determine the budgetary impact, the acceptability of the intervention and participation barriers and facilitators for Spanish-speaking stroke caregivers. Discussion: This is an ongoing study. It is the first known randomized controlled trial testing the effect of a telephone and online problem-solving intervention in Spanish for caregivers of veterans post-stroke. If successful, findings will support an evidence-based model that can be transported into clinical practice to improve the quality of caregiving post-stroke.

Objective: To assess changes in walking function and walking-related prefrontal cortical activity following two post-stroke rehabilitation interventions: an accurate adaptability (ACC) walking intervention and a steady state (SS) walking intervention. Design: Randomized, single blind, parallel group clinical trial. Setting: Hospital research setting. Subjects: Adults with chronic post-stroke hemiparesis and walking deficits. Interventions: ACC emphasized stepping accuracy and walking adaptability, while SS emphasized steady state, symmetrical stepping. Both included 36 sessions led by a licensed physical therapist. ACC walking tasks recruit cortical regions that increase corticospinal tract activation, while SS walking activates the corticospinal tract less intensely. Main measures: The primary functional outcome measure was preferred steady state walking speed. Prefrontal brain activity during walking was measured with functional near infrared spectroscopy to assess executive control demands. Assessments were conducted at baseline, post-intervention (three months), and follow-up (six months). Results: Thirty-eight participants were randomized to the study interventions (mean age 59.6 ± 9.1 years; mean months post-stroke 18.0 ± 10.5). Preferred walking speed increased from baseline to post-intervention by 0.13 ± 0.11 m/s in the ACC group and by 0.14 ± 0.13 m/s in the SS group. The Time × Group interaction was not statistically significant (P = 0.86). Prefrontal fNIRS during walking decreased from baseline to post-intervention, with a marginally larger effect in the ACC group (P = 0.05). Conclusions: The ACC and SS interventions produced similar changes in walking function. fNIRS suggested a potential benefit of ACC training for reducing demand on prefrontal (executive) resources during walking.
