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.

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.

Inter-hand transfer of the effects of unilateral isometric resistance training for wrist flexion and extension / 中华物理医学与康复杂志

Objective To investigate the effects on one hand of training the other with isometric wrist extension and flexion training and its underlying mechanism.Methods Twenty healthy young girls were recruited and randomized into a training group and a control group with 10 subjects in each,using a random number table.The subjects in the training group were accepted isometric training of the wrist extensors and flexors on the right side once every other day,4 days a week for 6 weeks according to a pre-programmed protocol,while those in the control group had no intervention.Peak torque and surface electromyography (sEMG) were recorded and assessed before and after 6 weeks of training.Results In the training group,the average peak torque of right wrist flexion and extension were both significantly higher than before training (within-group comparison) and higher than in the control group (between-group comparison) after 6 weeks of training.The average peak torques of the left wrist in the training group in flexion and extension were (12.9±2.0) Nm and (6.4 ± 1.3) Nm after training,both significantly higher than before the training and stronger than the control group.In the sEMG traces during wrist extension,after training the ascend velocity of the right extensor carpi ulnaris and the integrated area of the left extensor carpi ulnaris in the training group were significantly smaller than before training and in the control group.Conclusion Unilateral isometric resistance training of the wrist muscles can transfer to the contralateral side,probably by altering muscle recruitment.

Effect of Muscle Strength Training on Urinary Incontinence and Physical Function: A Randomized Controlled Trial in Long-term Care Facilities

PURPOSE: This study was done to determine whether muscle strength training programs have an impact on improving symptoms of urinary incontinence (UI) and physical function among elderly women with UI who reside in long-term care facilities. METHODS: A randomized controlled trial was conducted. Participants had to be over 65 years, score over 15 score on the mini-mental state examination, and be able to walk alone or with an assistant. Seventy residents were randomly allocated to either the training group (n=35) or control group (n=35). The program consisted of 50 minutes, twice a week for 8 weeks, and included Kegel's exercise, Thera-band training and indoor walking. Main outcomes were UI symptoms, peak vaginal pressure and physical functions measured with timed up and go test (TUG), one leg standing test (OLST), activities of daily living (ADL) and grip strength. Changes in outcome measurements were calculated from baseline to 4 weeks and to 8 weeks using repeated measures ANOVA. RESULTS: There were significant differences in peak vaginal pressure (p<.001), TUG (p<.001), OLST (p=.012) and grip strength (p<.001) in the interaction between groups and time. CONCLUSION: Future studies are suggested to confirm the effect of muscle strength training in long-term care facilities where elderly women with UI reside.
