基于LabVIEW的肌力测评系统

肌肉功能检查和评估是康复医学上评定康复治疗程度的重要指标,不仅为医生对病人的康复提供了正确的指导依据,而且在教练对运动员的训练中也发挥极其重要的作用,因此在康复医学的临床实践和科学研究中有广泛的应用前景。该文利用LabVIEW虚拟仪器开发平台,结合可编程自动化控制器(PAC)和各类传感器,基于串口通信协议,构建了综合肌力测评系统。同时利用LabSQL实现了对患者基本信息和测试信息的存储,便于比较训练期间患者康复的情况。文中重点介绍了测评系统的结构和各软件功能模块实现的关键技术。实验表明,该系统运行稳定,界面友好,易于操作。

产后盆底肌肌力测评方法及影响因素研究进展

女性骨盆底是封闭骨盆出口的软组织，由多层肌肉和筋膜组成。其中盆底肌肉是盆底组织的重要组成部分，其功能也是育龄妇女生殖健康的重要指标。妊娠和分娩会对盆底肌肉和神经造成损伤，使产后尿失禁、大便失禁、盆腔脏器脱垂的发生率升高。

老年人力量测评研究进展——基于“健康老龄化”背景下的功能发挥视角

“健康老龄化”是从健康和医疗角度应对人口老龄化的有效路径。在“健康老龄化”概念框架下,维持老年人的功能发挥应该是老年人健康促进的最终目标,因而,老年人的健康评估也应基于功能发挥视角展开。本研究基于世界卫生组织提出的“健康老龄化”概念框架下的功能发挥视角,对肌肉力量与老年人功能发挥、老年人主要功能评估工具的研究进展进行了概述,并对基于功能视角开发的,在老年人力量测评中被广泛使用的握力、手臂弯举和坐站测试3项测试指标的测试意义、测试方法,以及和健康的关系等研究进行了综述和展望。

Validity and reliability of three methods of stiffness assessment

Background：Stiffness is commonly assessed in relation to injury and athletic performance.The purpose of this research was to compare the validity and reliability of 3 in vivo methods of stiffness assessment using 1 cohort of participants.Methods：To determine inter-day reliability,15 female netballers were assessed for stiffness twice within 1 week using unilateral hopping（vertical stiffness）,free oscillations of the calf,and myometry of various muscles of the triceps surae.To establish convergent construct validity,stiffness was compared to static and dynamic strength measurements.Results：Test–retest stiffness results revealed that vertical stiffness produced moderate to high reliability results and myometry presented moderate to very high reliability.In contrast,the free oscillation technique displayed low to moderate reliability.Vertical stiffness demonstrated a significa t correlation with rate of force development during a squat jump,whilst myometer stiffness measurements from 3 sites in the lower limb revealed significan correlations with isometric rate of force development.Further,significan negative correlations were evident between the eccentric utilisation ratio and various myometer stiffness results.No relationships were established between the free oscillation technique and any of the performance measurements.Conclusion：These results suggest that vertical stiffness and myometry are valid and reliable methods for assessing stiffness.

Using nutritional assessment to predict gender-specific risks of sarcopenia among the elderly receiving health check-up in Taipei

Quality of life for the elderly in an ageing society is receiving more attention than ever. After age 40, muscle mass loses at the rate of 3% to 8% every 10 years. More- over, the decline intensifies after 60 years old. Although many people do not experience changes in total body weight, their muscle mass is slowly replaced by body fat. Decreased muscle mass means lower muscle strength, which affects physical functioning. As a result, daily activities become con- strained, risks of fall and bone fracture elevated,

Effects of rolling manipulation with different durations on erector spinae muscle tonus and low back pain in patients with lumbar muscle strain

Objective:To observe the effects of rolling manipulation with different durations on erector spinae muscle tonus and low back pain in patients with lumbar muscle strain and to explore the best duration for rolling manipulation in treating lumbar muscle strain.Methods:A total of 75 patients who met the inclusion criteria were randomized into a 5-minute rolling manipulation group,a 10-minute rolling manipulation group,and a 15-minute rolling manipulation group using the random number table method,with 25 cases in each group.All three groups were treated with the same rolling manipulation,while the treatment time was 5 min,10 min,and 15 min,respectively.The treatment was performed 3 times a week for 2 consecutive weeks.The muscle tonus of bilateral erector spinae and visual analog scale(VAS)score for low back pain were compared among the three groups before and after treatment.Results:A total of 63 patients completed the study.Before treatment and after the last treatment,there were no statistical differences in the muscle tonus of the left erector spinae and right erector spinae among the three groups(P>0.05).After the last treatment,bilateral erector spinae muscle tonus dropped compared with the baseline in all three groups(P<0.01).Before treatment and after the last treatment,there were no significant differences in comparing the low back pain VAS score among the three groups(P>0.05).After the last treatment,the VAS score for low back pain in all three groups decreased(P<0.01).Conclusion:Under the condition that the forward swing force is 50-70 N,the backward swing force is 20-40 N,and the frequency is 138 times/min,the 5-minute rolling manipulation can significantly reduce the muscle tonus of erector spinae and relieve low back pain.

Clinical study on warm needling moxibustion plus isokinetic muscle strength training in treating knee osteoarthritis

Objective:To observe the clinical efficacy of warm needling moxibustion plus isokinetic muscle strength training for knee osteoarthritis(KOA).Methods:A total of 135 patients with KOA due to Yang deficiency and coagulated cold were randomized into a warm needling moxibustion group,an isokinetic muscle strength training group,and a combined group by the random number table method,with 45 cases in each group.The warm needling moxibustion group was treated with warm needling moxibustion.The isokinetic muscle strength training group was treated with isokinetic muscle strength training.The combined group was treated with warm needling moxibustion plus isokinetic muscle strength training.The Western Ontario and McMaster Universities osteoarthritis index(WOMAC)and visual analog scale(VAS)were scored before and after treatment,and isokinetic indicators of peak torque(PT),total work(TW)and average power(AP)were evaluated.Results:The total effective rate of the combined group was 92.5%,which was significantly higher than 83.3%in the warm needling moxibustion group(P<0.05)and 72.5%in the isokinetic muscle strength training group(P<0.05).After treatment,the scores of WOMAC(total,pain,stiffness,and function)and VAS,and isokinetic indicators(PT,TW,and AP)were all improved compared with those before treatment(P<0.05)in all three groups.The differences among the three groups were statistically significant(P<0.05).The WOMAC total score and score of stiffness in the combined group were lower than those in the warm needling moxibustion group and the isokinetic muscle strength training group(P<0.05),and the scores in the warm needling moxibustion group were lower than those in the isokinetic muscle strength training group(P<0.05).The WOMAC score of pain and VAS score in the warm needling moxibustion group and the combined group were lower than those in the isokinetic muscle strength training group(P<0.05).The differences between the warm needling moxibustion group and the combined group were not statistically significant(P>0.05).The WOMAC function score in the combined group was lower than that in the warm needling moxibustion group and the isokinetic muscle strength training group(P<0.05),while there was no statistical difference between the warm needling moxibustion group and the isokinetic muscle strength training group(P>0.05).PT,TW,and AP in the combined group were higher than those in the warm needling moxibustion group and the isokinetic muscle strength training group(P<0.05),and they were higher in the isokinetic muscle strength training group than in the warm needling moxibustion group(P<0.05).Conclusion:Warm needling moxibustion plus isokinetic muscle strength training has a better effect in the treatment of KOA due to Yang deficiency and coagulated cold than either warm needling moxibustion or isokinetic muscle strength training alone.
