Post-ACL reconstruction surgery rehabilitation dataset using isokinetic dynamometer and wearable IMUs

Rehabilitation post-ACL reconstruction surgery is a lengthy process that involves a variety of exercises, with the goal of achieving leg symmetry. Testing for leg symmetry generally involves a series of tests, which may include walking gait analysis, isokinetic dynamometry, and single leg hop, if able. Isokinetic dynamometry readings have proven useful in understanding leg symmetry by providing a reading of muscle torque during a specific motion. However, the use of surface electromyography (sEMG) may provide further insight into the rehabilitation state of a patient's leg when placed on the mid thigh, by measuring the electrical muscle activity during an exercise. In a cohort of 22 participants (10 healthy, 12 patients), we collected sEMG data during isokinetic dynamometry leg extensions at 90 and 180 degrees. One sEMG sensor was placed on each vastus lateralis, in line with the muscle fiber orientation at the distal 1/3 of the measured distance from the greater trochanter to the super...
