Abstract: Both isokinetic testing and functional tests are commonly used to
evaluate patients following reconstruction of the anterior cruciate ligament
(ACLR). To determine the relationship of scores on an isokinetic test to scores
on a variety of lower extremity functional tests ten healthy subjects and
eleven ACLR patients at least six months after surgery performed knee
isokinetic test at 60 and 180 deg/sec and three functional tests: leg vertical
jump, single hop, and triple cross-over hop for distance. Correlation
coefficients of isokinetic peak torque to body weight and functional testing
were not significant at the P<0.05 level in patients or control subjects,
whi1e ratio of involved to uninvolved knee quadriceps isokinetics peak torque
and Limb Symmetry Index (LSI) of functional test were significant at the
P<0.05 level (r=0.54 to 0.97). These results indicate a significant
relationship between the LSI of various functional tests and side-to-side ratio
of isokinetic testing just in ACLR patients.
