Telehealth Intervention Involving HEARTS Technical Package and Activity Monitor to Promote Physical Activity Post-stroke
- Conditions
- Stroke
- Registration Number
- NCT06068036
- Lead Sponsor
- Federal University of Minas Gerais
- Brief Summary
Objectives: The aim of this feasibility randomized controlled trial (RCT) study is to investigate whether the theoretically informed telehealth intervention involving the HEARTS Technical Package and the use of an activity monitor to increase physical activity level post-stroke is feasible and to estimate the parameters for conducting a fully powered RCT.
Design: A Phase 1 feasibility RCT study with blinded assessment will assign eligible participants to experimental or control group. Participants in both groups will undergo a theoretically informed telehealth intervention based on the HEARTS technical package (a face-to-face session and telephone call follow-up). The experimental group will have additional use of the Mi Band 7® Smartwatch activity monitor. For both groups, the intervention will last for 12 weeks. The feasibility outcomes will be identified considering the different phases of conducting the study. A trained researcher, blinded to the group allocation, will collect the sociodemographic, anthropometric, and clinical outcomes, in a university laboratory setting.
Study Outcomes: Feasibility of recruitment, intervention, and measurement, and clinical outcomes.
Conclusions: Results from this feasibility RCT study will inform on the design and sample required for a fully powered RCT with a similar aim.
- Detailed Description
Standard Operating Procedures: A non-probabilistic sample will be recruited from the community. Recruitment strategies include: referrals (e.g, phone numbers obtained from other research projects and university extension programs) and advertisements (e.g. physical folders distributed in public places, and electronic pamphlets published on social media). All subjects will be informed about the study procedures and will provide written consent. The feasibility outcomes will be identified considering the different phases of conducting the study. A trained researcher, blinded to the group allocation, will collect the sociodemographic, anthropometric, and clinical outcomes, in a university laboratory setting. Two independent examiners, blinded to the group allocation, will enter the data into a statistical software package, verify any missing or apparently wrong values. Original paper forms will be kept in a secure place. Electronic files will be available only to the research team. Analysis will be carried-out by a researcher, blinded to the group allocation. All individuals will receive an identification code to ensure anonymity.
Statistical analyzes: All analyzes will be performed using SPSS (SPSS Inc., Chicago, IL, USA). Descriptive statistics will be calculated for all outcomes. The effect sizes will be calculated to determine the magnitude of within-groups and between-groups comparisons. The level of significance will be set at 5% and adjusted for multiple comparisons.

- Primary Outcome Measures
Name Time Method Feasibility of intervention (perceived effectiveness) At post-intervention (week-12). It will be determined by the following question: "Comparing how it was before you carried out the intervention and now, do you think that your ability to perform routine physical activity is: much worse, moderately worse, a little worse, the same, a little better, moderately better, or very better?".
Feasibility of intervention (retention) At allocation and post-intervention (week-12). It will be determined by the ratio between the total number of individuals who completed the proposed intervention program and the total number of individuals who started the proposed intervention program.
Feasibility of intervention (follow-up of individuals) At allocation, post-intervention (week-12), and one month after the end of the intervention (week-16). It will be determined the ratio between the total number of individuals who remained in the same group to which they were initially allocated until follow-up and the total number of individuals who were allocated.
Feasibility of intervention (safety) During the intervention (12 weeks) and follow-up (4 weeks). It will be determined by the number and reasons of adverse events (e.g. pain, falls, hospitalization, and death) identified during the period of intervention and follow-up of the individual.
Feasibility of intervention (attendance) At allocation and post-intervention (week-12). It will be determined by the ratio between the total number of sessions performed and the total number of sessions offered.
Feasibility of measurement At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). It will be determined by the percentage of clinical outcomes measured (ratio between the number of clinical outcomes measured and the number of clinical outcomes proposed to be measured), and the percentage of participants who filled-out the diary (ratio between the number of individuals who filled-out the diary and the number of individuals who started the proposed intervention program).
Feasibility of recruitment At enrolment and allocation. It will be determined by the ratio between the total number of eligible individuals (EI) and the total number of screened individuals (SI) (measure=EI/IS), and by the ratio between the total number of eligible individuals (EI) and the total number of recruited individuals (RI) (measure=EI/RI).
- Secondary Outcome Measures
Name Time Method Physical activity level At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Human Activity Profile (HAP). One of the outcomes provided by the instrument is the Maximum Activity Score (MAS). From the MAS, the Adjusted Activity Score (AAS) can be found by subtracting from the MAS the number of activities that the individual provided as the answer "I stopped doing". Higher scores indicate better outcome.
Self-efficacy for physical activity At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Self-efficacy for Physical Activity Scale. The scale has 10 items and has two response options: "Yes" is computed as 1 and "No" is computed as 0. The total score is defined by the sum of the scores for each item. The minimum total score is 0 and the maximum total score is 10. The higher the total score, the higher the self-efficacy for physical activity.
Health-related quality of life At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Stroke Specific Quality of Life Scale (SS-QOL). The scale has 49 items across 12 domains (items are rated on a 5-point Likert scale) and has three different sets of responses (indicated on the scale). The total score is defined by the sum of the scores for each item. The minimum total score is 49 and the maximum total score is 245. The higher the total score, the better the health-related quality of life.
Number of post-stroke individuals who became physically active At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Human Activity Profile (HAP). One of the measures provided by the questionnaire is the "Activity Rating", which provides an overall rating of the respondent's activity level into "Inactive", "Moderately active" and "Active".
Systolic and diastolic blood pressure At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Tycos® aneroid sphygmomanometer (WelchAllyn Inc., NY, USA, Model DS44) and stethoscope (Litmann Classic II SE 3M®, USA).
Lifestyle-related energy consumption At baseline, post-intervention (week-12), and one month after the end of the intervention (week-16). Human Activity Profile (HAP). One of the measures provided by the questionnaire is the "Lifestyle-related energy consumption", which provides a measure of actual oxygen consumption estimated from the "Activity Adjusted Score" (AAS). This measure is operationalized in ml.kg-1.min-1. Higher scores indicate better outcome.
