Research has shown that grip strength can be related to and predictive of other health conditions though not causative. Let me break down some of the health conditions grip strength can be positively related to: bone mineral density or osteoporosis, increased mortality from cardiovascular disease and from cancer in men, frailty and disability later in life.

Looking at that list, measuring grip strength is pretty darn important. The purpose of using a hand dynamometer is to measure the maximum isometric strength of the hand and forearm muscles. The hand dynamometer can be adjusted for hand size and must be calibrated regularly for consistent results.

Also, having clear protocols regarding technique in the administration of the test will also ensure reliability. Using the hand dynamometer is easy enough.

The patient holds the dynamometer in the hand being tested, with the arm at right angles with the elbow by the side of the body. Adjust the handle of the dynamometer as necessary, making sure that the base rests on the first metacarpal heel of the palmwhile the handle rests on the middle of the four fingers.

The patient then squeezes the hand dynamometer with maximum isometric effort for at least 5 seconds. The patient is required to not move any other part of the body and is encouraged to use maximum effort. Depending on the position of the arm and hand, different results can be achieved.

The various positions include: the instructions per above, the arm hanging by the side and the extended arm swung above the head then out to the side during the squeezing motion. A patient will do several trials of the test, resting for 15 seconds between each test. The best result of each trial is the one that is recorded. Below is a guide of expected results for adults. The values shown are an average of best scores for each hand.

And sure, there are other tests which can be used to test the strength of other muscles groups. But what the hand dynamometer does is give a reliable and simple measurement which can be used as a predictor of future health concerns.

Its simplicity, cost-effectiveness and time efficiency make the hand dynamometer a useful tool in any physical therapy clinic. And remember, you can tell the character of a person by the quality of their handshake, but you can also use it to help predict the quality of their future. How to use a Hand Dynamometer The purpose of using a hand dynamometer is to measure the maximum isometric strength of the hand and forearm muscles.

Handgrip strength is important for any sport in which the hands are used for catching, throwing or lifting.

Also, as a general rule people with strong hands tend to be strong elsewhere, so this test is often used as a general test of strength. See also the finger pinch strength test.

Prepare forms and record basic information such as age, height, body weight, gender, hand dominance. Calibrate dynamometer, adjust to suit the subject.

See more details of pre-test procedures. The handle of the dynamometer is adjusted if required - the base should rest on the first metacarpal heel of palmwhile the handle should rest on middle of the four fingers.

When ready the subject squeezes the dynamometer with maximum isometric effort, which is maintained for about 5 seconds. No other body movement is allowed. The subject should be strongly encouraged to give a maximum effort. See videos of the Handgrip Strength Test. Various positions include the elbow being held at right angles as per the above procedure, the arm hanging by the side, and the extended arm being swung from above the head to by the side during the squeezing motion.

The Eurofit Test Manual recommends squeezing for 3 seconds. The procedure for the Groningen Elderly Tests has the subject hang their hand by their side, one practice trial, best of three attempts with 30 seconds rest between. The values listed below in kg and lbs give a guide to expected scores for adults. These values are the average of the best scores of each hand. See more Hand Grip Strength Norms. Other protocols will just use the score from the dominant hand, or compare the left and right hand results.

See also examples of some actual athlete results. If you wish to measure the strength of a particular muscle group, there are other specific tests that can be performed. Having consistent technique and adequate rest is required to ensure reliability.

For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed rpm. A dynamometer can also be used to determine the torque and power required to operate a driven machine such as a pump. In that case, a motoring or driving dynamometer is used.

A dynamometer that is designed to be driven is called an absorption or passive dynamometer.

A dynamometer that can either drive or absorb is called a universal or active dynamometer. In addition to being used to determine the torque or power characteristics of a machine under test MUTdynamometers are employed in a number of other roles.

In standard emissions testing cycles such as those defined by the US Environmental Protection Agency US EPAdynamometers are used to provide simulated road loading of either the engine using an engine dynamometer or full powertrain using a chassis dynamometer. In fact, beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities such as the calibration of engine management controllersdetailed investigations into combustion behavior and tribology.

In an engine dynamometer, water flow, proportional to the desired applied load, creates resistance to the engine. A controlled water flow through the inlet manifold is directed at the center of the rotor in each absorption section.

This water is then expelled to the outer dynamometer body by centrifugal force. As it is directed outward, the water is accelerated into pockets on the stationary stator plates where it is decelerated. The continual acceleration and deceleration causes the dynamometer to absorb the power produced by the engine. Through this transfer of energy the water is heated and discharged.

An integral component of a dynamometer is its data acquisition system. The system is typically comprised of two units, a Commander and Workstation, connected by an Ethernet cable. The Commander, a desktop computer operated by Windows-based software, issues commands to the Workstation, a touch-screen operated unit housed in a rugged industrial enclosure.

The Workstation operates the precision load and throttle control systems, collects the data, and sends it to the Commander to be processed, stored and analyzed. The Workstation's success, and therefore the data acquisition system's accuracy, depends on its ability to correctly measure data in the dynamometer tests.

Central to these measurements is the precision of its pressure transducerswhich measure airflow in the intake manifold, oil pressure and other fluid pressures. The operator is interested in different pressures of fluids so having the capability of bringing in different pressures while running the engine is very important.

A high performance pressure transducer such as the AccuSense Model ASM is required because of its ability to measure accurately in rugged conditions. It can withstand mechanical shock and vibration, thermal shock, corrosion, and other extremes found in harsh testing environments of dynamometers. Another advantage is its flexibility. Versatility is typically required in the pressure ranges that customers are sensing.

Setra can customize the Model ASM to meet key specifications because the engine tester often requires uncommon ranges. The AccuSense Model ASM pressure transducer has a large number of standard pressure ranges and can also customize ranges to accommodate any unique pressures a customer may have.

The capacitive design of the AccuSense Model ASM allows for simple modifications to meet customer specifications with fast delivery time. Setra Systems, Inc. All Rights Reserved.
