[Effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training for postoperative rehabilitation of meniscectomy under arthroscopy].

OBJECTIVE: To observe the effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training on the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy. METHODS: A total of 70 patients after meniscectomy under arthroscopy were randomized into an observation group (35 cases, 2 cases were eliminated， 2 cases dropped off) and a control group (35 cases, 2 cases were eliminated, 1 case dropped off). Acupuncture was applied at Chize (LU 5), Neixiyan (EX-LE 4), Dubi (ST 35),Yanglingquan (GB 34), etc. on the affective side in the two groups. After 30 min, the needles of the knee joint area were withdrew, while the needle at elbow was continuously retained, the observation group was given acupuncture exercise therapy synchronizing isokinetic muscle strength training, and the control group was given conventional acupuncture exercise therapy. The treatment was given once a day, 7-day treatment was taken as one course, and totally 4 courses were required in the two groups. Before and after treatment, the knee joint Lysholm score, the knee joint isokinetic muscle strength flexion/extension ratio (H/Q), joint position sense measurement (JPS) and Hamilton anxiety scale (HAMA) score were compared in the two groups. RESULTS: After treatment, the knee joint Lysholm scores and H/Q were increased compared with those before treatment in the two groups (P<0.001), and the knee joint Lysholm score and H/Q in the observation group were higher than those in the control group (P<0.001); the JPS and HAMA scores were decreased compared with those before treatment in the two groups (P<0.001), the JPS and HAMA score in the observation group were lower than those in the control group (P<0.05). CONCLUSION: Acupuncture exercise therapy synchronizing isokinetic muscle strength training can effectively improve the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy.

Effects of Isokinetic Flexion and Extension Training at Different Angular Velocities on Core Muscles of Patients with Low Back Pain / 中国康复理论与实践

Objective:To explore the effect of isokinetic muscle strength training at different angular velocities on the core muscles of patients with low back pain, and to find out the better angular velocity. Methods:From January, 2016 to June, 2018, 60 patients with chronic low back pain were randomly divided into three groups, with 20 cases in each group. Group A (control group) only received routine rehabilitation therapy. Additionally, groups B and C received isokinetic muscle strength training at 30°/s and 90°/s, respectively, three times a week for four weeks. They were measured peak torque and average power before and after training. Results:After training, the peak torques and powers of both flexor and extensor were higher in groups B and C than in group A (P < 0.05), the peak torques of both flexor and extensor were lower in group C than in group B (P < 0.05), however, no significant difference was found in powers of both flexor and extensor between groups B and C (P > 0.05). After training, the score of VAS decreased in groups B and C (t > 4.098, P < 0.01), and was lower in groups B and C than in group A (P < 0.05), however, no significant difference was found between groups B and C (P > 0.05). Conclusion:Isokinetic muscle strength training could increase the peak torque and power of trunk flexor and extensor in patients with low back pain, in which lower angular velocity (30°/s) has a better effect.

Study on the control of variable resistance for isokinetic muscle training system.

BACKGROUND: Isokinetic muscle strength training is presently the most advanced method of muscle strength training. However, the existing control schemes of the training equipment are usually limited to the structure of the brake. OBJECTIVE: In order to solve this problem, this paper presents a solution to an isokinetic system based on the force control of a DC servomotor. METHODS: A new fuzzy impedance nonlinear controller is designed by analyzing the relevant requirements of isokinetic motion. A series of force tracking comparison experiments between a fuzzy PI controller and a classical PI controller are studied. In addition, some strength training experiments employing different driving forces and target speeds are also conducted. RESULTS: The results demonstrate the effectiveness of this fuzzy impedance force tracking control strategy. CONCLUSION: Using the aforementioned methods, a comprehensive motion algorithm was designed.

Clinical Study of Electroacupuncture on Acupoints Located Along Anterior and Posterior Thigh Muscles Plus Isokinetic Muscle Strength Training in Treating Poststroke Lower Limb Dysfunction / 广州中医药大学学报

Objective To observe the therapeutic effect of electroacupuncture (EA) on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training for poststroke lower limb dysfunction. Methods Fifty-two qualified mild hemiplegia cases were randomized into control group A ( N=17) , control group B (N=17), and observation group (N=18 ). Control group A was given conventional rehabilitation training, control group B was given conventional rehabilitation training and task-targeting knee strength-coordination isokinetic muscle strength training based on visual feedback, and observation group was given EA on acupoints located along anterior and posterior thigh muscles plus the treatment for control group B. The treatment for the three groups was performed once a day, five days a week, lasting 3 weeks. Before and after treatment, the lower limb motor function, peak torque ( PT) of knee flexion and extension muscles, and gait speed and gait symmetry were monitored. Results After treatment for 3 weeks, the lower limb motor function, PT and gait symmetry were much improved in the three groups (P0.05) , the improvement of observation indexes of control group B was superior to that of control group A, and the improvement of observation indexes of observation group was more obvious than that of the two control groups ( P<0.05) . Conclusion EA on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training is more effective for improving lower limb motor function of poststroke lower limb dysfunction patients than conventional isokinetic training.
