Stepping up Aerobic Exercise to Improve Health Outcomes After Stroke "STROKE-TRIC"

Phase N/A Results N/A

Trial Description

Stroke is a leading cause of chronic disability here in Nova Scotia and globally. Aerobic exercise is known to improve health by increasing energy levels, physical mobility, balance, bone health, cardiovascular risk reduction, mental well-being, cognition, sleep, and quality of life. Nonetheless, people remain woefully inactive after stroke, regardless if they are in hospital or at home. The current investigative team and others have shown that even during physiotherapy, exercise intensity is not adequate to increase physical fitness. Consequently, patients are often deprived of a treatment that could improve their recovery. Why does this gap between evidence and clinical practice persist? Through a national survey the current team found that an important contributing factor is lack of appropriate screening (especially stress tests) to ensure that patients are safe to engage in aerobic exercise. This project is designed to close this evidence-practice gap by establishing a state-of-the-art aerobic exercise screening and prescription clinic at the Nova Scotia Rehabilitation Centre (NSRC). The intent is to compare outcomes of stroke rehabilitation participants before and after the clinic is underway and determine if the clinic has a positive effect on the confidence of NSRC physiotherapists to use aerobic exercise safely and effectively in stroke rehabilitation.

Detailed Description

Research question: To what extent does an on-site aerobic exercise screening and prescription clinic effect uptake of aerobic exercise and patient outcomes in in-patient stroke rehabilitation?
Design: Pre-post cohort design to explore real-world application and feasibility
Aim 1. Establish an aerobic exercise screening and prescription clinic (herein 'Aerobics Clinic') at the NSRC.
Aim 2. Assess the potential impact of the Aerobics Clinic on the self-efficacy of physiotherapists at NSRC regarding clinical utilization of aerobic exercise in in-patient stroke rehabilitation.
Method: An assessment of the physiotherapy participants' self-efficacy regarding the clinical utilization of aerobic exercise post-stroke will be conducted prior to, and after, implementation of the Clinic.
Aim 3: Assess the potential impact of the Aerobics Clinic on prescription and treatment practices regarding aerobic exercise among patients in stroke rehabilitation at the NSRC.
Method: Prior to, and after, implementation of the Clinic the actual utilization of aerobic exercise in the practices of the physiotherapy participants will be assessed using heart rate monitoring, activity monitoring, and health record review.
Aim 4: Evaluate the potential impact of the Aerobics Clinic on performance measures and patient-reported outcomes between admission and discharge from in-patient stroke rehabilitation.
Method: Outcome measures related to aerobic fitness and patient-reported outcomes will be administered for each patient at admission and discharge by a trained, independent evaluator.

Conditions

Interventions

  • Aerobic Exercise Screening and Prescription Clinic Behavioral
    Intervention Desc: Patients will be referred to the Clinic by their physiotherapist to be assessed regarding their safety and readiness to participate in aerobic training. If they are deemed to be safe and ready, an aerobic exercise prescription will be written to guide the implementation of a safe and effective training protocol. Patients deemed to be at moderate to high risk will need to be cleared for testing by a physician on the stroke service. A cardiologist will be consulted about specific concerns re cardiac status.
    ARM 1: Kind: Experimental
    Label: Pre-Clinic Stroke Group
    Description: In- or out-patients with diagnosis of ischemic or hemorrhagic stroke who have been referred to the NSRC prior to the establishment of the Clinic and are willing/able to provide written informed consent and have no contraindications to exercise testing. Utilization of aerobic exercise will be monitored during their physiotherapy sessions (Aim 3), and aerobic fitness and related patient-reported outcomes will be assessed at admission and discharge (Aim 4).
    ARM 2: Kind: Experimental
    Label: Post-Clinic Stroke Group
    Description: In- or out-patients with diagnosis of ischemic or hemorrhagic stroke who have been referred to the NSRC after the establishment of the Clinic and are willing/able to provide written informed consent and have no contraindications to exercise testing. Each patient will undergo an assessment in the Aerobics Clinic and will receive a prescription for aerobic training based on the assessment findings. Utilization of aerobic exercise will be monitored during their physiotherapy sessions (Aim 3), and aerobic fitness and related patient-reported outcomes will be assessed at admission and discharge (Aim 4).
