About this study

This study aims to evaluate the effect of isometric handgrip (IHG) training on functional capacity and autonomic function before and after sternotomy. Open-heart surgery causes significant physiological stress, functional decline, and autonomic dysfunction. Patients undergoing sternotomy will be assessed for 6-minute walk test (6MWT), heart rate recovery (HRR), hemodynamic stability, rate pressure product (RPP), handgrip strength, and anxiety level. The intervention group will perform IHG training at 30% of maximal voluntary contraction, 2 minutes contraction per hand followed by 1 minute rest, for 20 minutes daily, 2-3 days before surgery and 24 hours once the patient is stabilized after sternotomy, in addition to standard care sessions (breathing and mobilization exercises). This low-cost, safe intervention aims to improve early cardiac rehabilitation, reduce complications, and enhance functional recovery.

Being tested
Isometric Handgrip Training using analog hand dynamometer, Standard care including breathing and motor exercises

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Isometric Handgrip Training using analog hand dynamometerOther

    Isometric hand grip training performed using an analog hand dynamometer (baseline type) at 30% of maximal voluntary contraction. Protocol: 2 minutes contraction per hand followed by 1 minute rest, total duration 20 minutes per session, once daily for 2-3 days before sternotomy and starting 24 hours after surgery once the patient is hemodynamically stabilized. Performed in addition to standard physiotherapy.

  • Standard care including breathing and motor exercisesOther

    Standard care: performed twice daily (morning and afternoon) for control group and once daily (afternoon) for IHGT group, 20 min per session: 1) Respiratory exercises (10 min): passive manual expiratory therapy 2 sets x 10 reps, fractional inspiration in times 3 sets x 10 reps, diaphragmatic breathing 3 sets x 10 reps. 2) Motor exercises (10 min): active exercises for upper and lower limbs, stationary walking 2-3 min, overground ambulation 3 min, and gradual stair training 1-2 flights (5-10 steps) based on hemodynamic stability.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Six Minute Walk Test - Functional Capacity

    Functional exercise capacity assessed by total distance walked in meters during 6-Minute Walk Test performed in a 30-meter corridor at self-paced speed . Heart rate, blood pressure, oxygen saturation and perceived exertion recorded before and after test for safety.

    Measured: Baseline 2-3 days before surgery and at hospital discharge up to 7 days postoperatively

Secondary outcomes (6)
  1. Heart Rate Recovery

    Difference between peak heart rate after exercise and heart rate after 1 minute of recovery as indicator of autonomic function

    Measured: Baseline 2-3 days before surgery, day before surgery, 24-48 hours after surgery, and at discharge up to 7 days

  2. Hand Grip Strength

    Maximal hand grip strength measured by calibrated handheld dynamometer in standardized seated position with elbow flexed at 90 degrees, highest value of 3 maximal voluntary contractions recorded in kilograms

    Measured: Baseline 2-3 days before surgery, day before surgery, 24-48 hours after surgery, and at discharge up to 7 days

  3. Heart rate

    Heart rate measured at peak exercise and after one minute of recovery, measured by pulse oximetry, as raw Values for Hemodynamic Response, Recorded in bpm

    Measured: Baseline 2-3 days before surgery, day before surgery, 24-48 hours after surgery, and at discharge up to 7 days

  4. Resting and post-exercise Blood Pressure

    blood pressure measured by aneroid sphygmomanometer before and after exercise, Measured in mmHg

    Measured: Baseline 2-3 days before surgery and at hospital discharge up to 7 days postoperatively

  5. Rate Pressure Product

    Rate Pressure Product calculated as heart rate multiplied by systolic blood pressure as indicator of myocardial oxygen consumption, Recorded in mmHg.bpm

    Measured: Baseline 2-3 days before surgery and at hospital discharge up to 7 days postoperatively

  6. Anxiety

    Anxiety level assessed by Visual Analogue Scale for Anxiety VAS-A, 10 cm horizontal line from no anxiety to extreme anxiety

    Measured: Baseline 2-3 days before surgery, day before surgery, 24-48 hours after surgery, and at discharge up to 7 days

Questions about this trial

What is this clinical trial studying?

A study testing Isometric Handgrip Training using analog hand dynamometer in people with Sternotomy and Functional Capacity, run by Cairo University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Six Minute Walk Test - Functional Capacity (time frame: Baseline 2-3 days before surgery and at hospital discharge up to 7 days postoperatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
