INTRODUCTION: The purpose of this study was to examine the effect of 6 week pre-operative home based exercise on muscle strength and proprioceptive functions after anterior cruciate ligament(ACL) reconstruction.
METHOD: Forth ACL reconstruction patients were randomly assigned into two groups; Pre-op Exercise Group (PEG, n=20) and Pre-op Non-Exercise Group (PNEG, n=20). PEG participated in 6weeks of home-based pre-op and 12 weeks of post-op exercise while PNEG participated only in the 12 weeks of post-op exercise. They were tested on muscle strength and proprioceptive functions 6 weeks before operations and 3 months after operations. Knee strength measurements at 60°/sec and 180°/sec on an isokinetic dynamometry were analyzed to compare their muscle strength. proprioceptive functions have been assessed using joint position sense and dynamic postural stability.
RESULT: The deficit of the knee extensor peak torque of uninvolved/involved at 60°/sec and 180°/sec were significant difference between PEG and PNEG. In PEG, deficit of the knee extensor peak torque of uninvolved/involved was reduced by 36.19% to 22.58% and 29.67% to 18.65%, respectively. In dynamic postural stability index test, PEG showed a significantly improved instability of 12.6% whereas PNEG resulted that of 23.3%(p=0.0231). However, no significant difference was found between PEG and PNEG in joint position sense test .
CONCLUSION: The 6 week home-based pre-op exercise may encourage many positive changes for ACLR patients by reducing the deficit between uninvolved and involved knees and improving proprioceptive functions.
