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

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.

Inclusion criteria

  • individuals under 45 years of age who performed at least 4 hours of physical activity per week.

Exclusion criteria

  • individuals unable to perform isokinetic muscle tests
  • individuals with a current or recent lower limb injury with time loss from sport participation within the previous month
  • individuals with previous severe knee injury (eg. Severe ligament tear, knee fracture)

Treatment and study plan

All group

Device

All the participants performed the isokinetic proprioception and strength tests and the functional tests, on the same visit.

Primary outcomes

  1. Strength

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

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

  2. Knee proprioception, JPS1

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

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

  3. Knee proprioception, JPS2

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

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

  4. Knee proprioception, TDPM

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

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

  5. Functional testing, Hop tests

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

    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)
