ABSTRACT

Objective To observe the effect of isokinetic training of knee flexors and extensors on walking ability in patients with knee osteoarthritis(KOA). Methods From December,2016 to June,2017,120 patients with KOA in our hospital were randomly divided into blank group(n=40),control group(n=40)and observation group(n=40).All the groups were injected with sodium hyal-uronate intraluminally,and received joint mobilization.The control group added conventional strength training, including isotonic and isometric static squat exercise of muscles around the knee. The observation group re-ceived knee isokinetic training additionally,the training mode was ordinary isokinetic/centripetal mode.Before and four weeks after treatment, the peak torque (PT), the Lysholm score and Visual Analogue Scale (VAS) for pain,ten-meter walking time and six-minute walking distance were tested. Results After treatment,the PT value of knee flexors and extensors,the scores of VAS and Lysholm,ten-meter walking time and six-minute walking distance significantly improved in all groups(P<0.05),among which the observa-tion group was the best(P<0.05). Conclusion Isokinetic muscle strength training of knee flexors and extensors can improve the walking ability of patients with KOA.

ABSTRACT

Objective To study the effects of different ranges of isokinetic quadriceps training for improving the func-tion of knee joint after total knee arthroplasty (TKA),and provide the theoretical and clinical experiences for the early reha-bilitation of TKA.Methods A total of 73 TKA cases were randomly allocated into 3 groups for isokinetic quadriceps train-ing with ranges of 0°-30° (n=25), 31°-60° (n=24) and 61°-90° (n=24). The isokinetic quadriceps training was for two months. The isokinetic muscle strength and the IKS scores were recorded before and after the training in three groups. Re-sults After training, the isokinetic muscle strength increased significantly in three groups (P<0.05). The IKS scores in-creased significantly only in 0°-30° training group after training (P<0.05). There was no significant difference in IKS score before and after training in 31°-60° group and 61°-90°group. The IKS score after training was positively correlated with the isokinetic muscle strength only in 0°-30° group (P<0.05). Conclusion After TKA, isokinetic quadriceps training with a 0°-30° range of motion can improve the strength of quadriceps and the knee function.

ABSTRACT

Objective To explore the effects of isokinetic training on muscle endurance and the ambulatory capacity of patients with incomplete lumbar spinal cord injury ( SCI ) . Methods Sixty patients were randomly divided into a control group and a treatment group, each of 30. Both groups were given conventional rehabilitation, while the treatment group was additionally provided with isokinetic muscle strength and muscle endurance training for 3 months. The endurance ratio ( RO) of the quadriceps and hamstrings, the mean power frequency of the rectus femo-ris (RF-MPF) and the biceps flexor cruris (BF-MPF), and distance covered in the 6-minute walk test (6MWT) were evaluated before and after the treatment. An index of functional community ambulation was also compared be-tween the 2 groups. Results After the treatment significant differences were observed in all of the measurements compared to before the treatment for both groups. The average RO improvement of the quadriceps and hamstrings, the BF-MPF, the RF-MPF and the 6MWT distance of the treatment group were all significantly higher compared with the control group. After the treatment, 25 patients of the treatment group could demonstrate functional community ambula-tion, significantly better than that of 20 of the control group. Conclusion Isokinetic training can improve muscle endurance and the walking capacity of persons with an incomplete lumbar spinal cord injury.

ABSTRACT

We investigated the effect of scapular stabilization exercise on shoulder joints mobilization and pain release in youth baseball players. Total 15 youth baseball players were voluntarily participated, and randomly divided into one of two experimental groups: either stabilization exercise group (EXE, n=7) or control group (NonE, n=8). Stabilization exercises (i.e., punching, scapular retraction, scapular fold, shrug, pull over, seated press, scaption with retraction, body blade, rotator cuff) were administered to EXE (8 weeks, 3 times.wk(-1), 60-100 min.session(-1)). Muscular power using Biodex system 3, full range of motion (ROM) with a goniometer, and the degree of pain with the Visual Analogue Scale was assessed at both baseline and the time point of completion of 8 weeks training program. Twoway ANOVA (group vs. time) was adopted to observe any interactive effects between factors. The statistical significance level was set at alpha=.05. There was an improvement in muscular power at both slow (i.e., 60degrees/sec) and medium (i.e., 180degrees/sec) speed setting in isokinetic instrument during internal and external rotation on dominant shoulder, and internal rotation only (not with external rotation) on non-dominant shoulder. There was no change in ROM in NonE, but total ROM was significantly expanded in EXE, revealing only degree of internal rotation increased. VAS significantly decreased in EXE. In conclusion, scapular stabilization exercise exerted positive effect on muscular power output, full range of motion and pain release on shoulder joint in youth baseball players. This indicates that scapular stabilization exercise possibly exert meaningful effect in injury prevention and sport performance.

ABSTRACT

Objective To analyze the data of concentric (c) and eccentric (e) peak torque of hamstring (H) and quadricep (Q) in differ-ent gender and angle after 4-week concentric and eccentric isokinetic exercise training on knee, in order to provide suggestions for the knee extensor and flexor in rehabilitation exercise prescription. Methods 28 healthy college students from May to June 2014 in our college partic-ipated in maximum concentric (n=14) or eccentric (n=14) resistance training of the right knee extensors and flexors 3 times per week for 4 weeks. The concentric strength was measured with BIODEX isokinetic dynamometer assessment system 4 at 30 °/s, 60 °/s, 90 °/s, and ec-centric strength was measured at 60 °/s, 120 °/s, 180 °/s. PT, H/Q (He/Qc, Hc/Qc) ratio and H/H (He/Hc) or Q/Q(Qe/Qc) ratio were ana-lyzed. Results Concentric isokinetic training could improve the Hc and He at 60 °/s and 90 °/s (P0.05). After concentric isokinet-ic training, the He/Qc ratio decreased at 90 °/s (P0.05). The Qc/Qe ratio increased at 60 °/s and 90 °/s (P0.05). There were significant differences in Hc, He, Qc, Qe and He/Qc ratio between different genders (P<0.05). Conclusion Concentric training and ec-centric training have different influences on the muscle strength after 4 weeks training. Eccentric training only can reduce the knee stability. Hc/He ratio and Qc/Qe ratio can be used to evaluate the knee muscle function. Gender should be considered into training.

ABSTRACT

Objective To evaluate the effects of isokinetic quadriceps training with different ranges of motion for improving mal-patellar tracking after total knee replacement (TKR). Methods Isokinetic quadriceps training was administered to 52 TKR cases, involving 66 knee joints with poor patellar tracking. The subjects were randomly allocated into 3 groups for isokinetic training with ranges of 0-30°, 30-60° or 60-90°, with 22 knee joints in each group. The angular velocity was set at 30°/second. X-rays with loading and with 45° knee flexion were taken before and after the training. The lateral patello-femoral angle,the patella index and the patello-femoral index were recorded along with the maximum torque ( MT), the total work ( TW ), and the average work(AW) in the three different ranges of motion. Hospital for Special Surgery (HSS) scores were also recorded. Results After 3 months of training, the average lateral patello-femoral angle, patella index, and patello-femoral index in the 0-30° training group were all significantly better than before the training. However, there was no significant difference in these measures for the 30-60° and 60-90° groups. After training average MT, TW and AW increased significantly in all groups, but the improvements were significantly correlated with the differences in lateral patello-femoral angles, patella indices and patello-femoral indices only for the 0-30°group. When compared with the baseline values, a statistically significant difference in HSS score after training was observed only in the 0-30° training group. Conclusions Isokinetic quadriceps training with a 0-30° range of motion can best realign patellar tracking after TKR, and best improve knee function.
