Impact of elbow position on grip strength of elderly men.

Grip strength is frequently measured in rehabilitation settings in order to monitor patient progress. Many factors influence grip strength measurements, including body segment positions and particularly elbow position. The objective of this study was to compare grip strength measurements obtained with two different elbow positions: full extension and 90 degrees of flexion. Forty-nine healthy right-handed men aged 60 to 84 years were tested with a Jamar dynamometer. Results indicated that left grip strength was significantly higher when the elbow was flexed to 90 degrees compared with when it was fully extended. No statistical difference between the two elbow positions was found for the dominant hand.
