Normal jamar dynamometer grip strength what are the normal jamar dynamometer grip strength results for 35 year old for both dominant/nondominant upper extremity

Hand : Hand size, occupation, general health and a variety of issues play a role. A good gauge is the strenght of the opposite unaffected hand. The domnant hand is typically 10-15% stronger than the non-dominant hand however the median value is 105 pounds in one study...See study below remember this is one study in report.

There : There is no such thing as "normal" for this test. The results are widely variable based on hand size, occupation, hobbies, previous injuries, and effort. The point is not to compare you to others, but to compare you to yourself. Your non-dominant hand should have about 80% of the dominant side. While going through a therapy program, the numbers should be increasing. The measurements are also used to see how consistently effort is being applied. The readings can be distorted by using the wrong setting on the device for your hand size, so make sure it is done with the same setting for consistent results. Some therapists will test a range of settings. They should always record which position was used. Also, the device needs to be calibrated regularly. Try 2 different devices and see what the variation is. If they are widely different, then at least one of them needs to be calibrated.

I : I would add to the discussion that there is a voluntary element to grip strength. If you are in pain, you may not feel secure about giving a good effort.

The : The rapid alternating test is very good identifying malingerers. The sustained grip test done in a computerized system gives you some great curves with objective evidence of a maximum effort test as compared to a malingerer.
