A method of measuring finger force with the Kin-Com dynamometer.
The purpose of this study was to determine whether the force of a finger could be measured with a new system based on an attachment to the Kin-Com dynamometer, and to define the reproducibility of the finger force measurement. Eleven male subjects (age, 27.6 +/- 6.12 years) took part. All were free of orthopedic problems in the tested hand. Mean forces of the index and little finger for concentric and eccentric motion were measured using the new system. Overall coefficients of variation (OCVs) were calculated as an index of reproducibility. The reproducibility of force curves was considered good when an OCV was less than 20%. The OCVs for mean force of the index finger and for eccentric motion of the little finger were less than the 20% standard, at 10.7 and 14.0, respectively. The OCV for concentric motion of the little finger was greater than 20%. The findings suggest that measurement of finger force is feasible with the new Kin-Com attachment.
