About this trial
The purpose of this study is to assess the impact of an isokinetic strength training of knee flexor and extensor muscles on walking performance in hemiparetic patients with knee extension thrust.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Hemiparetic patient (hemorragic or ischemic stroke)
Subacute stage (< 6 Months) ou chronic stage of stroke (> 6 months) (6 patients in each group)
Age between 18 and 75 years
Able to walk 10 meters independently without any assistive devices
Disqualifiers
Major comprehension deficit that not allow to give informed consent and participate to isokinetic strength training (assessed with comprehension subscore of Langague screening Test)
non stable (unstable cardiovascular condition)
musculoskeletal disorders with knee pain that not allowed isokinetic strength training
Botulinum toxin injection less than 3 months or repeated injection in lower limb,
Trial design
Factorial
Treatments tested in this trial
isokinetic strength training of knee extensor and flexor muscles
BehavioralPatients underwent an isokinetic strength training program with 3 sessions per week during five weeks. Program consists of excentric contraction of knee flexor and extensor muscles (4 x 7 Contractions at 30°/s) and concentric contractions at maximal speed where patients can perform 40% of his maximal isometric torque for knee flexor and extensor muscles (2x10 for knee flexors and 2x10 for knee extensors)
Treatment groups
Trial outcomes
Primary outcomes
spontaneous walking speed

Extensor thrust at spontaneous and maximal walking speed and during dual task recorded with 3D gait analysis
Walking speed
assessment of walking speed in two conditions (maximal speed and dual task)
Stairs test
time to ascend and descend stairs (maximal speed)
Inclined plan
time to walk in an inclined plan (maximal speed)
