Isokinetic Training On Knee Osteoarthritis Rehabilitative Application Study

Objective: The aim of this investigate was to explore under the laws of the state of passive movement active isokinetic concentric knee isokinetic eccentric strength training combined with traditional isotonic isometric strength training combined to compare, from the clinical perspective in patients with osteoarthritis of the knee Isokinetic training in rehabilitation for the treatment of short-term clinical efficacy. Osteoarthritis of the knee rehabilitation provide a comprehensive, effective and reasonable exercise treatment. Combination of isokinetic concentric isokinetic eccentric strength training in reducing pain, increased knee, improve activities of daily living knee knee symptoms and improve the therapeutic effect. In the isokinetic strength training, the use of isokinetic concentric and eccentric isokinetic strength training model combining motion, so that patients with knee extensor and flexor strength training contraction, respectively, in the whole process of strength training Play isokinetic concentric and eccentric isokinetic strength training role.Methods: Binzhou Medical College Hospital with pain in knee OA rehabilitation of 42 patients, the diagnostic criteria are in line with knee OA, willing to accept the rehabilitation treatment, were randomly divided into the principle of eccentric isokinetic concentric isokinetic strength training group combined treatment group (A group ), isometric strength training combined with isotonic control group (B group). 22 cases were male and 20 female. The average age of 60.5 years (37 to 74 years) the average weight of 58.3kg (46 ~ 80kg). Treatment group: use of isokinetic training BIODEXSYSTEM-4 instrument on the third group of knee isokinetic strength speed training for four weeks, followed by isokinetic eccentric strength training four weeks. Set the speed and order: fast 120% / s, the speed of 90% / s, slow 60% / s, each training session divided into three groups, each practice 20min. Training 3 times a week, a total of 8 weeks to practice. Knee extension and flexion range from 15°flexion to flexion 90°. Control group: isometric training for four weeks, followed by isotonic training for four weeks, eight weeks. Isometric training: straight leg raising method used by the light of Sun Qiliang (straight leg raising exercise, SLR). Beginning of the training before the maximum load test, the patients with straight leg raising 10°~ 15°, and can maintain a maximum load of 5 s, whichever is 1 / 3 as the daily training load. To 20 times as a group, twice daily group. Isotonic training: use of isotonic quadriceps training device, the Dolorme progressive load training (progressive resistance exercise, PRE). After the treatment, pain points, respectively, knee joint, knee range of points, knee daily activities (ADL) ability points and total score of 4 clinical index score, analyzed statistically, comparing two rehabilitation interventions for knee Clinical efficacy of bone and joint disease.Conclusion:KOA strength in the course of the change is important. Knee flexor, extensor strength declined a direct impact on the stability of the knee; with knee Zhou tendons, ligaments and other soft tissues of the strength decreased, making the joint stability and further decline. Knee instability and can lead to tibiofemoral joint, patellofemoral joint surface stress anomaly. Promote the deterioration of KOA. Enhance muscle strength, improve the stability of the knee is one of the key recovery KOA. Therefore, whether to break the muscle from atrophy, joint instability, pain and the vicious circle between the three to consider, or departure from the ability to improve sexual function, muscle strength exercises are indispensable. Isokinetic concentric isokinetic eccentric training with regular training in continuous passive motion of the state to enhance and improve muscle strength and performance of resistance training methods, which can effectively play their respective role on the advantages of the muscle can play a complementary role in the same time. Isokinetic strength training of the model is effective and safe is good.
