Squeezing a hand device at home lowered systolic pressure
In Thailand, 30 older adults with hypertension were randomized. After eight weeks, systolic pressure fell more with grip exercises than with no-resistance gripping.
The key idea
After eight weeks of at-home grip exercises, systolic pressure fell more than in the comparison group. Grip strength improved in both.
The study, in plain language
The idea fits at home: squeeze a grip device without moving the wrist or arm. In Thailand, a trial randomized 30 people over 60 with hypertension, 15 per group. One group did these exercises for eight weeks, while the other did gripping without resistance.
In the exercise group, systolic and diastolic pressure fell, and the systolic decrease was larger than in the comparison group. Grip strength improved in both groups, so the contrast favoring training was in systolic pressure. There are limitations: a small sample, office blood-pressure measurements on the same arm used for exercise, and no long-term follow-up.
What they found
- The program used a commercial hand-grip device for home practice.
- Systolic pressure fell more with training than in the comparison group.
- Grip strength improved in both groups, so the favorable contrast appeared in systolic pressure.
Something to think about
When an exercise is said to change blood pressure, ask how many people tested it and for how long. Here, it was 30 people over eight weeks.
How they studied it
Researchers randomized 30 adults over 60 with hypertension in Thailand to practice hand-grip exercises at home or grip without resistance, 15 per group. The intervention lasted eight weeks. Blood pressure was measured in the office and grip strength was also assessed.
What the study cannot show
- Small sample; office blood-pressure measurements on the same arm used for exercise; last-observation-carried-forward imputation; and no long-term follow-up.
- The study does not establish long-term effects or effects in the general population or patients with different characteristics. It does not show that exercise replaces medication or other clinical measures; any treatment change should be discussed with a health professional.
