Unlocking the Secrets of Handshake Strength and Health Indicators
Written on
Chapter 1: Understanding Hand-Grip Strength
When evaluating your overall health, medical professionals often start by checking vital signs like temperature, blood pressure, pulse, and respiratory rate. But what about hand-grip strength?
Hand-grip strength (HGS) is not yet recognized as a standard vital sign measured during medical assessments, but many experts advocate for its inclusion as an essential fifth vital sign.
Section 1.1: What is Hand-Grip Strength?
In simple terms, "hand-grip strength" refers to the amount of force one can exert with their hand. While a handshake can provide a basic sense of someone's grip strength, a more precise measurement can be taken using a dynamometer. This device resembles a video game joystick equipped with a pressure gauge, which patients squeeze as hard as they can. The resulting force is displayed on a dial.
To ensure accuracy, it is advisable for clinicians to test both hands—taking care to note which is dominant—three times and then average the results. This non-invasive test can be completed quickly and offers valuable insights.
Section 1.2: The Insights Gained from Grip Strength
Experts suggest that hand-grip strength can not only reflect your current health status but also predict potential health issues and longevity. This simple measurement is particularly important for the elderly, serving as a biomarker for overall strength, vitality, and the risk of conditions like fractures, nutritional deficiencies, and chronic illnesses.
Interestingly, there is a growing consensus among researchers that hand-grip strength should be monitored in individuals of all ages as it may indicate lifelong health outcomes.

The Weird Thing Everyone Does After A Handshake explores the social dynamics of handshakes and what they reveal about us.
In a long-term study conducted in Sweden, over a million adolescents underwent grip strength assessments along with other basic health checks. After 24 years, researchers found that stronger grip strength during adolescence correlated with a 20-35% lower risk of premature death from any cause, including cardiovascular diseases, regardless of body mass index or blood pressure.
Grip strength testing is also useful for individuals of all ages to gauge their aging process. Regular assessments can alert both patients and healthcare providers to declining muscle function, which often foreshadows broader health issues.

Section 2.1: Advancements in Grip Strength Testing
Researchers are enthusiastic not only about the wealth of insights obtainable from basic grip strength tests but also about the potential for more sophisticated assessments. These advanced tests could evaluate factors like the rate of force development and the asymmetry of grip strength between hands. Recent studies indicate that significant discrepancies in strength may signal impending health challenges and functional disabilities.
Furthermore, grip strength testing has emerged as a valuable tool for identifying new or poorly understood health conditions. For instance, it plays a crucial role in recognizing long Covid, where diminished hand strength can indicate ongoing recovery challenges.
Section 2.2: Cost-Effectiveness and Future Considerations
Whether utilizing a simple dynamometer or more advanced methods, grip strength testing is a low-cost yet invaluable addition to routine health assessments. Although it has not yet been officially recognized as a fifth vital sign, patients are encouraged to inquire about this test during their next medical check-up. Understanding your hand-grip strength could provide vital insights into your overall health.
