研究目的:

本研究目的从分析骨骼肌组织结构改变出发,采用新型脂肪评估技术UDFF 测定骨骼肌脂肪含量,探讨通过 UDFF 联合骨骼肌弹性超声检测手段在肌少症诊断中的价值,并构建肌少症的超声诊断模型,探讨超声诊断模型与老年患者骨折、跌倒、全因死亡的关系,为老龄化社会背景下老年肌少症的诊断提供一种精准、无创、简便、高经济效益比、可推广的新的检测手段,并为后期精准的康复指导提供依据。  

Objectives of Study:

The purpose of this study is to start from analyzing the changes in the skeletal muscle tissue structure, use the new fat assessment technique UDFF to measure the skeletal muscle fat content, explore the value of the combined use of UDFF and skeletal muscle elastic ultrasound detection methods in the diagnosis of sarcopenia, and construct an ultrasound diagnostic model for sarcopenia. It also aims to explore the relationship between the ultrasound diagnostic model and fractures, falls, and all - cause mortality in elderly patients. This study intends to provide a new, accurate, non - invasive, simple, cost - effective, and popularizable detection method for the diagnosis of sarcopenia in the elderly under the background of an aging society, and offer a basis for precise rehabilitation guidance in the later stage.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

肌少症评估 根据老年人肌少症防控干预中国专家共识(2023)中肌少症的诊断标准,完善 BIA 检测、握力、6 米步行速度检测。 1. 骨骼肌质量指数:使用 BIA 测量患者 ASM,获得 ASMI,诊断界值:BIA:男性: <7.0 kg/m^2,女性: <5.7 kg/m^2。 2. 握力测试:握力器的显示屏向外,使食指近掌关节保持垂直状态,受试者使用优势手测定,握力器尽量不要触碰身体或衣服,测定时不要让握力器来回摆,分别测量三次,取最高值,诊断界值:男性<28kg,女性<18kg。 3. 6 米步行速度:选好做好标记长为 6m 的宽敞明亮的场地,指导受测者着平时穿的鞋子,站到出发线上,听到 “开始”命令后,开始计时,受测者以平时行走的步态沿着被标记好的场地走,记录受测者六米步行的时间,至少测量两次,取平均时间,诊断界值:平均步行速度<1.0m/s。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Sarcopenia assessment: According to the diagnostic criteria for sarcopenia in the Chinese Expert Consensus on the Prevention and Control of Sarcopenia in the Elderly (2023), improve the detection of BIA, handgrip strength, and 6-meter walking speed. 1. Skeletal muscle mass index: Use BIA to measure the appendicular skeletal muscle (ASM) of the patient to obtain the appendicular skeletal muscle mass index (ASMI). Diagnostic cut-off values: For BIA, for men: <7.0 kg/m^2, for women: <5.7 kg/m^2. 2. Handgrip strength test: Keep the display screen of the handgrip dynamometer facing outwards, and keep the proximal metacarpal joint of the index finger in a vertical state. The subject should use the dominant hand for the measurement. Try not to let the handgrip dynamometer touch the body or clothes, and do not let the handgrip dynamometer swing back and forth during the measurement. Measure three times respectively and take the highest value. Diagnostic cut-off values: For men <28 kg, for women <18 kg. 3. 6-meter walking speed: Select a well-lit and spacious venue with a marked length of 6 meters. Instruct the subject to wear their usual shoes and stand on the starting line. After hearing the "start" command, start the timer. The subject should walk along the marked venue at their usual walking gait. Record the time it takes for the subject to walk 6 meters. Measure at least twice and take the average time. Diagnostic cut-off value: The average walking speed <1.0 m/s.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

待评估诊断试验名称:骨骼肌超声检测 检测体位:分别在松弛态(中立位)和紧张态(收缩位),对腓肠肌、比目鱼肌(俯卧位)、股四头肌(坐位)进行检查,规范体位角度以保证检测一致性。 探头放置:腓肠肌、比目鱼肌置于跟骨粗隆上 25cm 处,股四头肌置于髌骨上方 15cm 处,均轻贴皮肤不加压。 超声检测:使用西门子超声诊断仪(线阵探头 4-15MHz,肌骨系统模式),行二维超声(测量横截面积、羽状角)和实时 SWE(测量 SWV 最大值、最小值、平均值及标准差)。 辅助测量:采用 DAX 探头(UDFF 模式),在松弛态对目标肌肉扫查测量 5 次取平均值;随机选取 34 名参与者行下肢 MRI-PDFF 检测。

Index test:

Name of the diagnostic test to be evaluated: Skeletal muscle ultrasound examination Examination positions: Examine the gastrocnemius, soleus (in the prone position), and quadriceps femoris (in the sitting position) in the relaxed state (neutral position) and the tense state (contracted position) respectively. Standardize the body position angles to ensure the consistency of the examination. Probe placement: Place the probe 25 cm above the calcaneal tuberosity for the gastrocnemius and soleus, and 15 cm above the patella for the quadriceps femoris. All probes should be gently placed on the skin without applying pressure. Ultrasound examination: Use a Siemens ultrasound diagnostic instrument (linear array probe, 4 - 15 MHz, musculoskeletal system mode) to perform two - dimensional ultrasound (measure the cross - sectional area and pennation angle) and real - time SWE (measure the maximum, minimum, average values and standard deviation of SWV). Auxiliary measurement: Use a DAX probe (UDFF mode) to scan and measure the target muscles 5 times in the relaxed state and take the average value. Randomly select 34 participants for lower - limb MRI - PDFF examination.
