Association Between Knee Isokinetic Testing and Lower Limb Functional Performance and Limb Symmetry

Strength

Measurement of knee extensors and flexors peak strength (in newton.meter, Nm) on isokinetic dynamometer.

Time frame: one evaluation at a single point in time through study completion, an average of 4 months

Knee proprioception, JPS1

Measurement of knee proprioception by the passive repositioning technique (JPS, in degrees) on isokinetic dynamometer.

Time frame: one evaluation at a single point in time through study completion, an average of 4 months

Knee proprioception, JPS2

Measurement of knee proprioception by the active repositioning technique (JPS, in degrees) on isokinetic dynamometer.

Time frame: one evaluation at a single point in time through study completion, an average of 4 months

Knee proprioception, TDPM

Measurement of knee proprioception by the Threshold to Detection of Passive Motion (TDPM in degrees) on isokinetic dynamometer.

Time frame: one evaluation at a single point in time through study completion, an average of 4 months

Functional testing, Hop tests

Hop test. Single hop: Patients are instructed to stand on one leg and perform 1 jump as far as possible, landing on the same leg. The total distance is recorded (in cm) .Triple hop: Patients are instructed to stand on one leg and perform 3 hops as far as possible, landing on the same leg. The total distance for 3 consecutive hops is recorded (in cm). Cross-over hop test : The patient hops forward 3 times while alternately crossing over a marking The patient is instructed to position themselves such that the first of the 3 hops was lateral with respect to the direction of crossover The total distance hopped forward is recorded (in cm)

Time frame: one evaluation at a single point in time through study completion, an average of 4 months
