This study aimed to evaluate the association between the isokinetic knee strength and/or proprioception performance with the functional performance on the functional Hop-tests and Y-balance test.
This study included 20 healthy individuals who performed an isokinetic assessment of knee proprioception (joint position sense, JPS and threshold to detection of passive motion, TDPM) and flexors/extensors strength. At the same time, they performed a functional testing consisting of three Hop-tests (single, triple and cross-over) and the Lower Quarter Y-Balance Test (YBT-LQ). We tested the correlation between the isokinetic and functional performances, and limb symmetry indexes.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| All group | Device | All the participants performed the isokinetic proprioception and strength tests and the functional tests, on the same visit. |
| Measure | Description | Time Frame |
|---|---|---|
| Strength | Measurement of knee extensors and flexors peak strength (in newton.meter, Nm) on isokinetic dynamometer. | 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. | 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. | 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. | 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) | one evaluation at a single point in time through study completion, an average of 4 months |
