The effect of a forearm strap on wrist - extensor strength*.

Abstract

Thirty subjects with no pathology of the right elbow were tested using an isokinetic dynamometer to measure wrist extensor strength. Subjects were tested under control and experimental conditions with and without a forearm strap. Tests were conducted at 30 and 120 degrees /sec. Results were plotted on separate graphs using a sequential trials method. No difference in strength was noted at the slower speed. A statistically significant increase in strength with the strap was found at 120 degrees /sec. It was concluded that, in these subjects, the forearm strap made no difference in strength at the slower speed, but significantly increased strength at the faster speed. Facilitation due to sensory stimulation of the skin and pressure on the muscle belly was offered as an explanation. Further research is needed in this area.
