Hand Grip Training for High Blood Pressure
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if squeezing an inflatable ball (isometric hand grip training) can lower blood pressure in individuals undergoing cardiac rehab. Participants will be divided into two groups: one will engage in both cardiac rehab and the ball-squeezing exercise, while the other will participate only in cardiac rehab. Individuals with coronary artery disease, who have experienced a heart attack or undergone certain heart procedures, and can use a phone and email, may be suitable candidates. Participants will monitor their own blood pressure at home and share the results with researchers. The trial also evaluates the ease and mental health benefits of the ball-squeezing exercise. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could enhance cardiac rehab outcomes.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that isometric hand grip training is safe for lowering blood pressure?
A previous study found that isometric handgrip training (IHG) significantly lowered blood pressure in people with hypertension. Research shows that IHG can reduce blood pressure by more than 6/4 mm Hg, lowering both the systolic and diastolic numbers.
Regarding safety, some experts have concerns, but many studies highlight its effectiveness and consider it generally safe. Although no specific reports of serious side effects exist, caution is advised, especially for those with other health issues. Always consult a doctor if there are any uncertainties or concerns.12345Why are researchers excited about this trial?
Researchers are excited about isometric hand grip training for high blood pressure because it offers a non-drug approach to managing hypertension. Unlike standard treatments that typically involve medications like ACE inhibitors or beta-blockers, this method focuses on improving cardiovascular health through simple, hand-held exercises. This training is unique because it can be easily incorporated into daily routines without the side effects associated with medications. Additionally, it has the potential to enhance the effectiveness of existing cardiac rehabilitation programs by providing an accessible, low-cost way to help lower blood pressure.
What evidence suggests that isometric hand grip training is effective for lowering blood pressure?
Research shows that isometric hand grip (IHG) training can effectively lower blood pressure. Studies have found that IHG training significantly reduces blood pressure in people with hypertension, which is high blood pressure. This method excels at lowering both systolic blood pressure (when the heart beats) and diastolic blood pressure (when the heart rests). In this trial, one group will receive Cardiac Rehabilitation (usual care) plus Isometric Hand Grip training, while another group will receive Cardiac Rehabilitation only. Isometric exercises, like IHG, rank among the best types of exercise for lowering blood pressure. These findings suggest that adding IHG training to heart health programs could further reduce resting blood pressure.16789

Are You a Good Fit for This Trial?
This trial is for individuals participating in cardiac rehabilitation who also have high blood pressure. To join, participants must be able to perform isometric handgrip (IHG) training and willing to self-report their blood pressure. Details on specific inclusion or exclusion criteria are not provided.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants engage in cardiac rehabilitation with or without isometric handgrip training for 12 weeks
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Isometric Hand Grip Training
Trial Overview
The study tests if adding IHG training with an inflatable ball three times a week to regular cardiac rehab can lower resting blood pressure more effectively than just cardiac rehab alone. Participants will either do both IHG and CR or only CR, assigned randomly.
How Is the Trial Designed?
Cardiac Rehabilitation (usual care) PLUS Isometric Hand grip training
Cardiac Rehabilitation (usual care) Only
