Make sure you follow these guidelines when performing measurements. Failing to do so may lead to inaccurate results or cause the measurements to fail.
Please sit down and relax for 5 minutes before starting the measurements.
1. Sit upright with your back straight, your shoulders adducted, and your feet flat on the floor.
2. Bend your dominant arm at the elbow so the upper arm makes a straight angle (90 degrees) with the lower arm. Your forearm should be horizontal to the ground and unsupported as shown in the picture.
3. Close the fingers of your dominant hand around the bulb of the Eforto® Device so the thumb is on one side and the other fingers are on the opposite side.
4. Hold the Eforto® Device so that the wide end of the bulb is at the bottom and the enclosure is at the top.
5. Take the measurement in a calm and quiet area.
6. Stay still, and do not talk. Make sure to keep normal breathing while performing the measurements.
In some situations, this position will not be possible. In this case, a physician should advise you on the position you should adopt for your usage of the Eforto® Device.
Note: Grip strength measurements can be affected by the position of the Eforto® Device and your physiological and emotional condition.
