Official title
Effects of Isokinetic Strength Training of Knee Flexor and Extensor Muscles on Walking in Hemiparetic Patients With Knee Extension Thrust
Overview
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.
Detailed description
The study will be interventional single case experimental design (SCED) with multiple baseline design. SCED are experimental designs aiming at testing the effect of an intervention using a small number of patients using repeated measurements, sequential and randomized introduction of an intervention and method-specific data analysis, including visual analysis and specific statistics.
During baseline, patients will have a rehabilitation program in day hospital (4 days per week) with physiotherapy and physical activity and if necessary occupational and speech therapy. Isokinetic strength training will be added to this conventionnal rehabilitation program and will begin after 3, 4 or 5 weeks of baseline according to randomization
12 patients will be included in this study (6 patients in subacute stage and 6 in chronic stage ).
Interventions
- Behavioral isokinetic strength training of knee extensor and flexor muscles
Patients 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)
Primary outcome measures
- spontaneous walking speed [Time frame: 25 weeks]
Secondary outcome measures (10)
- Extensor thrust analysis [Time frame: 25 weeks]
- Walking speed [Time frame: 25 weeks]
- Stairs test [Time frame: 25 weeks]
- Inclined plan [Time frame: 25 weeks]
- 6-minute walk test [Time frame: 25 weeks]
- Sit to stand test [Time frame: 25 weeks]
- Extensor thrust during locomotor tasks [Time frame: 25 weeks]
- Fatigue [Time frame: 25 weeks]
- Likert Scale [Time frame: 25 weeks]
- Strength [Time frame: 25 weeks]
