The aim of this study was to develop and assess an isometric hand tester to
measure multiple strength parameters of the muscles of the hand. Nineteen men and
22 women took part in a first study and 17 men were tested in a second one. Five
different tests were developed: wrist flexion, wrist extension,
metacarpophalangeal joint flexion, thumb adduction and proximal and distal
interphalangeal joint flexion. Reliability was tested with an intraclass
correlation coefficient for single measures. When the results from men and women
were analysed separately,
all tests except metacarpophalangeal joint flexion and
thumb adduction produced intraclass correlation coefficients greater than 0.7.
Combining the genders gave intraclass correlation coefficients greater than 0.9
except for metacarpophalangeal joint flexion and thumb adduction. After adjustments, intraclass correlation coefficients for metacarpophalangeal joint
flexion and thumb adduction were between 0.70 and 0.83 in the second study. The
new isometric hand tests improve the measurement of intrinsic and extrinsic hand muscle strength.
