The handgrip maneuver is performed by clenching one's fist forcefully for a sustained time until fatigued. Variations include squeezing an item such as a rolled up washcloth.

Physiological Response[edit]

The handgrip maneuver increases afterload by squeezing the arterioles and increasing total peripheral resistance.[1]

Cardiology[edit]

Since increasing afterload will prevent blood from flowing in a normal forward path, it will increase any murmurs that are due to backwards flowing blood.[2] This includes aortic regurgitation (AR), mitral regurgitation (MR), and a ventricular septal defect (VSD).

Mitral valve prolapse: The click and the murmur of mitral valve prolapse are delayed because of the increased left ventricular volume.[3]

Murmurs that are due to forward flowing of blood such as aortic stenosis, and hypertrophic cardiomyopathy decrease in intensity.

Mitral stenosis: The diastolic murmur of mitral stenosis increases because of an increased heart rate, blood pressure and cardiac output.[4][5]

The effect of reducing the intensity in forward flowing murmurs is much more evident in aortic stenosis rather than mitral stenosis. The reason for this is that there is a larger pressure gradient across the aortic valve.[6] A complementary maneuver for differentiating disorders is the Valsalva maneuver, which decreases preload.
