Foot rotation—A potential target to modify the knee adduction moment

Isolating the particular joints/limb segments associated with knee adductor moment variability may provide clinically important data that could help to identify strategies to reduce medial tibiofemoral joint load. The aim of this study was to examine whether or not foot and thigh rotation during human locomotion are significant determinants of knee adductor moment variability.Three-dimensional gait analyses were performed on 32 healthy adult women (mean age 54 ± 12 years, mean BMI 25 ± 4 kg m⁻²) with radiologically normal knees. The relationships between foot rotation, thigh rotation and the external knee adduction moment were examined during early and late-stance phases of the gait cycle.The degree of foot rotation correlated significantly with the magnitude of the peak knee adduction moment during late stance (r = 0.40, p = 0.024). No significant associations were apparent between thigh rotation and the peak knee adduction moment.The association between foot rotation and the knee adduction moment in this study suggests that women who walk with external rotation at the foot reduce their knee adduction moment during late stance. This result implies that changes in foot kinematics can modify the medial tibiofemoral load during gait, which may be important in the prevention and management of knee osteoarthritis.

Philosophy,technical principles,selection, and indication in body contouring surgery

The experiences of almost three decades of performing various types of body contouring surgery, in both pre- and postlipoplasty periods, using many different techniques are described. Contouring surgery for such body areas as the abdomen, flanks, inner and outer thighs, and buttocks is discussed in detail.     

A Simple Ultrasound Correlate of Visceral Fat

The roles of body fat and muscle masses for developing cardiometabolic disorders are opposed to each other. The aim of this study was to analyze whether abdominal visceral to thigh muscle thickness ratio (AVTMR) measured by ultrasonography can be a simple yet useful index assessing the disproportion between visceral fat and thigh muscle, and whether it is associated with carotid atherosclerosis. This was an observational study performed on 15 healthy men and 68 men with newly-diagnosed type 2 diabetes. Using ultrasonography, abdominal visceral thickness, mid-thigh muscle thickness and carotid artery intima-media thickness (CA-IMT) were determined. The visceral fat amount and lipid-rich muscle mass were increased and metabolic profile was poorer across AVTMR tertiles. The AVTMR was associated an increased CA-IMT independent of traditional risk factors. The AVTMR measure using ultrasonography might be a relevant index identifying individuals at an increased risk of cardiovascular disease.     

削薄股前外侧皮瓣游离移植修复舌癌术后缺损的临床疗效

目的:探讨削薄股前外侧皮瓣游离移植修复舌癌术后缺损的效果.方法:选择2007年1月-2011年10月我院口腔科舌鳞状细胞癌患者28例,采用舌癌根治术后联合削薄股前外侧皮瓣游离移植修复术后造成的舌缺损,并对治疗效果和舌功能恢复效果进行随访观察.结果:本组28例患者皮瓣均完全成活,再造舌体及舌根部形态恢复正常,供受区创口均一期愈合,下肢运动感觉功能无障碍.经术后随诊,所有患者修复后舌形态功能恢复良好.结论:对舌癌联合根治术造成的舌缺损,应用削薄股前外侧皮瓣游离移植的临床效果较好,重建后的舌功能恢复也较为理想.

超声测量胎儿股骨皮下组织厚度预测胎儿体重的临床应用

目的：探讨B超测定胎儿股骨皮下组织厚度预测胎儿出生体重的临床价值。方法：应用B型超声对196例正常孕妇在分娩前5d内测量胎儿双顶径（BPD）、头围（HC）、腹围（AC）、股骨长（FL）、股骨皮下组织厚度（TSTT），并与新生儿体重的关系进行分析。经单元线性回归得出预测胎儿体重的单元方程式。结果：股骨皮下组织厚度与新生儿体重相关性最好（γ=0．865）。依据股骨皮下组织厚度可以初步预测胎儿出生的体重范围。其符合率达80．1％。结论：应用B型超声测量胎儿股骨皮下组织厚度预测胎儿出生体重，方法简单、准确，有较好的临床应用价值。

Long-term transcutaneous neuromuscular electrical stimulation in patients with bipolar sensing implantable cardioverter defibrillators: a pilot safety study

Neuromuscular electrical stimulation (NMES) is an option for increasing thigh muscle strength and endurance capacity in patients with chronic heart failure. Electromagnetic interference (EMI) by the signals with sensing of implantable cardioverter defibrillators (ICDs) is possible. The aim of the present pilot safety study was to test the safety of a long-term NMES in patients with ICDs. Six patients with subpectoral ICDs were subjected to long-term NMES of thigh muscles. Four inpatients received NMES to increase muscle strength, and two outpatients performed NMES as a home treatment to increase endurance capacity. During long-term NMES, all patients together received 14 139 799 biphasic electrical pulses and 412 425 on-phases without adverse events. ICD function after the stimulation period revealed no abnormalities in any patient. These results indicate that long-term NMES of thigh muscles seems to be safe in patients with ICDs, providing that an individual risk is excluded before.
