Haardekoormus

Haardekoormus, commonly translated as grip strength, is the maximal force that the hand can exert when gripping. It is typically measured with a hand dynamometer, with the subject’s arm positioned at the side and the elbow bent around 90 degrees, the wrist in a neutral position, and several maximal squeezes recorded. The highest value among trials, often with rest between attempts, is used for analysis. Measurements may be taken for both hands, and the dominant hand is usually stronger.

Haardekoormus is considered a general indicator of upper-body muscle strength and functional status. In clinical and research settings it is used to assess baseline strength, monitor rehabilitation progress, and screen for frailty or disability. Lower grip strength has been associated with higher risk of adverse outcomes, including functional decline, hospitalization, and mortality, particularly in older adults. Values are influenced by age, sex, height, body composition, and health conditions such as arthritis, nerve injury, or recent trauma. Posture, testing protocol, and equipment can affect results, underscoring the need for standardized procedures.

Normative data for haardekoormus vary by population, age group, and sex, so interpretation should reference appropriate reference values. Applications span geriatrics, physical therapy, sports science, and occupational health, where grip strength helps evaluate hand function, monitor treatment effects, and inform rehabilitation or training plans.
