About

Monitoring heart rate during exercise can provide feedback to the patient and provider that the patient is exercising in the appropriate, individualized and safe range for them. This is particularly important in a group setting when multiple individuals are supervised by one provider. This study is interested in assessing the difference in intensity of care delivered when visual feedback of heart rate is provided compared to no visual feedback of heart rate in rehabilitation. Visual feedback of heart rate will be provided through Heart Zones, a platform which synthesizes multiple signals from externally worn heart rate monitors. This study is interested in better understanding the acceptability, feasibility and appropriateness of this technology when used in rehabilitation.

Full description

OBJECTIVES:

The purpose of this investigation is to determine if knowledge of heart rate (HR) and target HR zones (HRzone), with visual feedback vs no feedback of HR or HRzone improves patient exercise intensity during rehabilitation. The central hypothesis for this study is with visual feedback of HR and target HR zones with instruction about exercise intensity and targets will increase patient HR intensity during sessions within a safe range set by their medical team. For purposes of this study, patients will be monitored in inpatient sessions and is inclusive of all individuals with chronic health conditions. Physical activity and exercise guidelines recommend everyone, including those with chronic health conditions, strive for 150 minutes of moderate intensity aerobic exercise per week. This study will contribute to the knowledge of how patients achieve recommended individual HR and moderate-high intensity zones during exercise.

Aim 1: Measure the extent to which monitoring and education regarding intensity is provided (1) when providers know HR monitoring is occurring but without visual feedback for the group, and (2) with visual feedback of HR monitoring in a group setting.

The investigators hypothesize providers will modify their behavior in the number of times they ask about intensity, adjust session intensity or provide education regarding intensity when visual feedback is provided compared to no feedback.

Aim 2: Determine the safety of using Heart Zones technology in rehabilitation settings for increasing participant exercise intensity.

The investigators hypothesize the technology will be safe without an increase in number of adverse events throughout their rehabilitation stay.

Aim 3: Assess patient acceptability, exercise self-efficacy and confidence following use of Heart Zones technology in group settings.

The investigators hypothesize use of Heart Zones technology in rehabilitation with feedback will increase participant self-efficacy and confidence in reaching higher exercise intensities, and will be well accepted.

18 participants in 1 patient group

Observational HR monitoring

Experimental group

Description:

Participants will receive 2 intervention conditions: HR monitoring with visual feedback, and HR monitoring without visual feedback. Observed condition will alternate by session. The investigators will monitor overall HR response, mean time HR and time in target zone, Rate of perceived exertion (RPE), and provider behavior to HR monitoring prior to HR monitoring, with visual feedback and without visual feedback. Visual Feedback of Multiple Participant Heart Rates: Visual feedback of HR is provided through a television (TV) monitor. Multiple heart rates can be displayed and recorded simultaneously allowing for group encouragement, continuous monitoring and adjustment of all participants to ensure reaching appropriate target intensity.
