Effects of Different Telerehabilitation Methods In Patients With Hypertension (TELE-HT)

This study aims to compare two different ways of providing exercise therapy to people with high blood pressure (hypertension) through digital technology. Participants are divided into two groups: one group performs exercises at home while being watched and guided by a physiotherapist in real-time through video calls (synchronous). The other group performs the same exercises by watching pre-recorded videos on their own (asynchronous). The study measures how these two methods affect the patients' exercise capacity, daily blood pressure levels, heart functions, and their ability to manage their own health over an 8-week period.

About this study

In this randomized, controlled, single-blinded study, 35 hypertensive individuals are assigned to either a synchronous telerehabilitation (STR) or an asynchronous telerehabilitation (ATR) group. Both groups perform an 8-week aerobic-based calisthenics program consisting of 24 sessions (3 sessions per week, 45 minutes each). The STR group exercises under the live supervision of a physiotherapist via videoconferencing. The ATR group uses pre-recorded video content and maintains an exercise diary. During all sessions, heart rate is monitored in real-time using wearable smartbands to maintain a submaximal intensity (70-85% of age-predicted maximum heart rate). Assessments performed at baseline and at the 8th week include ambulatory blood pressure monitoring (ABPM), transthoracic echocardiography (TTE), maximal stress tests, self-care inventories, physical activity and body composition.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Diagnosis of systemic hypertension.
  • Age between 18 and 65 years.
  • Access to the internet.
  • Ownership of a mobile device suitable for telerehabilitation participation.

Exclusion criteria

  • Presence of comorbid cardiovascular and/or pulmonary diseases.

Treatment and study plan

Synchronous Cardiac Telerehabilitation

Behavioral

An 8-week aerobic-based calisthenics program consisting of 24 sessions (3 sessions/week, 45 minutes each).

Exercises are performed in real-time under the live supervision of a physiotherapist via videoconferencing (WhatsApp).

Intensity is maintained at 70-85% of age-predicted maximum heart rate, monitored in real-time using a wearable smartband.

Exercises include high knees, knee-to-elbow, side jacks, and other calisthenics.

Other names: Home-based Exercise Training, aerobic exercise training

Asynchronous Cardiac Telerehabilitation

Behavioral

The same 8-week aerobic-based calisthenics program (24 sessions, 3 sessions/week) as the STR group.

Exercises are performed independently by participants using pre-recorded video content.

Participants maintain an exercise diary to record heart rate and blood pressure levels, which are reviewed weekly by a physiotherapist.

Exercise intensity is adjusted weekly based on data from the participant's wearable smartband.

Other names: Home-based Exercise Training, aerobic exercise training

Primary outcomes

  1. Exercise Capacity

    Time frame: Before and after the training (0 and 8th Week)

    Change in Functional Exercise Capacity (6-Minute Stepper Test); The number of steps completed within six minutes using a stepper device. Higher step counts indicate better functional capacity.

  2. Exercise Capacity

    Time frame: Before and after the training (0 and 8th weeks)

    Predicted maximal oxygen uptake; Calculated from the duration of the maximal stress test (Bruce protocol) using validated formulas for men and women. It represents maximal aerobic capacity in mL/kg/min.

Secondary outcomes

  1. Blood Pressure Levels

    Time frame: Before and after the training (0 and 8th weeks)

    Ambulatory Blood Pressure Monitoring (ABPM) Parameters; Mean 24-hour, daytime, and nighttime systolic (SBP) and diastolic blood pressure (DBP) levels measured in mmHg.

  2. Cardiac Functions

    Time frame: Before and after the training (0 and 8th weeks)

    Systolic functions assessed with echocardiography expressed by ejection fraction (EF, %) and diastolic functions E and A waves measured via transthoracic echocardiography (TTE). E wave represents early diastolic velocity, and A wave represents late diastolic velocity.

  3. Self-Care Levels

    Time frame: Before and after the training (0 and 8th weeks)

    Self-Care of Hypertension Inventory (SC-HI V3.0) Score; A 23-item Likert-type scale with maintenance, monitoring, and management subscales. Each subscale is scored from 0 to 100, where higher scores indicate better self-care.

  4. Postural Stability and Upper Extremity Function

    Time frame: Before and after the training (0 and 8th weeks)

    Plank test duration (in seconds)

  5. Lower Extremity Muscle Function

    Time frame: Before and after the trainining (0 and 8th weeks)

    Numbers of Squat

  6. Objective Physical Activity Level

    Time frame: Before and after the training (0 and 8th weeks)

    Average daily and weekly total step counts and weekly exercise duration were recorded using a wearable smart wristband

  7. Subjective Physical Activity Levels

    Time frame: Before and after the training (0 and 8th weeks)

    Self-reported PA levels according to the International Physical Activity Questionnaire (IPAQ) score. IPAQ includes vigorous, moderate and walking activities during the last seven days and higher scores reflect higher physical activity levels.

  8. Body Mass Index

    Time frame: Before and after the training (0 and 8th weeks)

    Body weight/ (height*height) (kg/m2)

  9. Body Composition-Anthropometric Measure

    Time frame: Before and after the training (0 and 8th weeks)

    Weight to height ratio (kg/cm)

  10. Body Fat Percantage

    Time frame: Before and after the training (0 and 8th weeks)

    body fat percentage (%) assessed by bioelectrical impedance analysis

  11. Fat Free Mass

    Time frame: Before and after the training (0 and 8th weeks)

    Fat Free Mass assessed by bioelectrical impedance analysis

  12. Lipid Profile

    Time frame: Before and after the training (0 and 8th weeks)

    Measured via blood samples including low-density lipoprotein (LDL) and high-density lipoprotein (HDL) levels in mg/dL.

  13. Cardiovascular Disease (CVD) Risk Profile

    Time frame: Before and after the training (0 and 8the weeks)

    Cardiovascular Disease (CVD) Risk Profile; Estimated using the SCORE-TR risk chart, which calculates the 10-year risk of fatal cardiovascular disease based on age, gender, smoking status, systolic blood pressure, and total cholesterol.

  14. Waist Circumference

    Time frame: Before and after the training (0 and 8th weeks)

    Waist Circumference in cm
