Telerehabilitation With Aims to Improve Lower Extremity Recovery Post-Stroke (TRAIL-RCT) (TRAIL-RCT)

Telerehabilitation With Aims to Improve Lower Extremity Recovery Post-Stroke (TRAIL-RCT): A Randomized Controlled Trial

The purpose of this study is to compare the effectiveness of a 4-week lower extremity telerehabilitation protocol with aims to improve lower extremity function to a 4-week attention-controlled education program on lower extremity clinical outcomes, quality of life, and healthcare resources utilization among community dwelling adults with stroke across Canada.

Detailed Description

With an aging population, and survival rates now at 83% in Canada, the number of stroke survivors is expected to reach 720,000 by 2038. While 90% of individuals with stroke return to independent community living, 80% report residual motor impairment, such as loss or limitation in motor control, or mobility limitation. These limitations have profound effects on the ability to perform everyday activities and are associated with substantial economic strain on the healthcare system. Thus, a primary focus of stroke rehabilitation is on the recovery of motor function, walking and balance, using exercise via physical therapy.

The rapid growth in Internet use and personal mobile devices has opened an array of possibilities for stroke survivors to remotely access specialized rehabilitation from their homes and communities (i.e., telerehabilitation). Telerehabilitation interventions have been used effectively for check-in sessions, education, and counselling after stroke, but knowledge of the effectiveness of using telerehabilitation for the delivery of exercise interventions for lower extremity recovery is limited.

The investigators developed the TeleRehabilitation with Aims to Improve Lower Extremity Recovery Post-Stroke (TRAIL) to address the unmet needs for lower extremity rehabilitation after stroke, and the need for accessible rehabilitation in the face of the COVID-19 pandemic. TRAIL is an exercise program designed to promote lower extremity recovery using technology with real-time therapist instruction and guidance. The investigators recently conducted a proof-of-concept, single-group feasibility study of TRAIL (TRAIL-PROOF). From TRAIL-PROOF, there were have no reports of serious adverse events and 100% retention of participants. Preliminary analysis of 32 individuals completed also suggest improvements in the clinical outcomes, including increased lower extremity strength, functional balance, and balance self-efficacy. Thus, from TRAIL-PROOF, it is evident that the TRAIL protocol has potential to improve lower extremity function among community-dwelling adults with stroke experiencing lower extremity impairment. The investigators now propose a full-scaled randomized controlled trial to further study the TRAIL program (TRAIL-RCT).

The objectives for TRAIL-RCT are as follows:

1. The primary objective is to compare functional mobility (Timed Up and Go, primary clinical outcome) after 4 weeks of TRAIL to a 4-week attention-controlled education program (EDUCATION) in individuals ≤12 months post-stroke;

2. The secondary objective is to compare the 4-week TRAIL and EDUCATION programs on secondary outcomes of:

   1. Lower extremity strength (30-Second Sit-to Stand test);
   2. Functional balance (Tandem Stand and Functional Reach);
   3. Motor impairment (Virtual Fugl-Meyer Assessment);
   4. Balance self-efficacy (Activities-specific Balance Confidence Scale);

3. The tertiary objective is to compare the 4-week TRAIL and EDUCATION programs on health economic outcomes:

   1. Health-related quality of life (Stroke Impact Scale, EuroQol-5D-5 Level); and
   2. Health resources and costs (Health Resource Utilization Questionnaire)
4. The quaternary objective is to evaluate the feasibility of a subsequent larger multisite implementation stepped wedge randomized trial of TRAIL using pre-specified criteria related to process, resources, management, and scientific indicators.

It is hypothesized that:

The primary hypothesis is that the 4-week TRAIL program will lead to greater improvement in functional mobility, as measured by the Timed Up and Go, compared to the 4-week EDUCATION program in individuals ≤12 months post-stroke (Objective 1, primary clinical outcome).

The investigators also anticipate that greater improvements will be observed in the secondary clinical outcomes, in the areas of lower extremity muscle strength, motor impairment, functional balance, and balance self-efficacy, following TRAIL compared to EDUCATION (Objective 2).

The tertiary hypothesis is that the TRAIL intervention will demonstrate superior health economic outcomes compared to the EDUCATION group (Objective 3).

The quaternary hypothesis is that the protocol will demonstrate sufficient feasibility (e.g., rates of recruitment/retention, treatment fidelity and adherence, safety, treatment effects) to support a subsequent larger multi-site implementation stepped wedge randomized controlled trial (Objective 4).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: TRAIL; TRAIL is a 4-week progressive exercise and self-management intervention for lower extremity recovery delivered by a trained registered physical therapist, in a 2:1 participant-to-therapist ratio. Each participant grouping will receive two telerehabilitation sessions (60-90 minutes) each week for 4 weeks (total 8-12 hours).	Other: TRAIL; Each week has a specific focus for lower extremity rehabilitation: Week 1) Building a base: 8 exercises, 10-15 repetitions x 2-3 sets Week 2) Increasing repetitions: 8 exercises, 15-20 repetitions x 3 sets Week 3) Building exercise tolerance:10 exercises, 15-20 repetitions x 3 sets Week 4) Maximizing repetitions: 10 exercises, 30 seconds as many reps as possible x 2 sets At the end of the second exercise session each week, the therapist and participants work collaboratively to develop an independent exercise action plan to be completed before the first session of the next week. The self-managed plans includes exercises selected from TRAIL, agreed upon by the participant and therapist, that are safe to perform without therapist oversight. The aims of the exercise action plan are to: i) Add exercise volume without using program resources (e.g., therapist time); and ii) Build capacity for self-management for long-term health and well-being after TRAIL has ended.
Active Comparator: EDUCATION; The EDUCATION control arm is a 4-week education program focusing on stroke knowledge and risk factors. It will be delivered by health professionals who have experience working with individuals with stroke, knowledge of chronic disease self-management (e.g. physical or occupational therapists, nurses, kinesiologists), and who have completed study-specific training on the EDUCATION program Participants will receive video conferencing sessions with the same schedule and 2:1 participant-to-coach ratio as TRAIL. Each participant grouping will receive two educational telerehabilitation sessions (60-90 minutes) each week for 4 weeks (total 8-12 hours).	Other: EDUCATION; EDUCATION has a specific focus on: Week 1) What is stroke (e.g., gaining an understanding of the function of the brain, types of stroke and how stroke affects physical function) and introduction to self-management; Week 2) What is self-management; Week 3) Self-management for post-stroke complications (e.g., activities of daily living); Week 4) Self-management for secondary prevention (e.g., blood pressure, diet, medication, stress management). Education therapists will be provided with lesson plans and manuals to be circulated with the participants, and will facilitate the educational session through interactive Powerpoint presentations. In addition, participants will be asked to complete 30-60 minutes of educational homework, which will be discussed at the commencement of the following session.
