Study summary

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.

What researchers measure

Primary outcomes

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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
