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

Completed

• Conditions: Proprioceptive Disorders

• Registration Number: NCT04885725
• Lead Sponsor: University Hospital, Caen

Brief 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.

Primary Outcome Measures

Name	Time	Method
Strength	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.
Knee proprioception, JPS1	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.
Knee proprioception, JPS2	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.
Knee proprioception, TDPM	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.
Functional testing, Hop tests	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)
