Abstract

Abstract: Reliability of muscle thickness assessed in B-mode ultrasound has been confirmed in adults but remains a less direct assessment of muscle mass than muscle volume (MV). The aim of this prospective monocentric study was to assess the interday reliability of MV determined by the 2D-panoramic ultrasound in older hospitalized patients.Ten participants hospitalized in geriatric ward (mean age = 84) underwent 2 sessions of panoramic ultrasound scanning 1 week apart for MV assessment and DXA for leg lean mass (LLM) assessment when it was possible. The interday reliability of MV assessed using the intraclass correlation coefficient (ICC) was excellent, whatever was the muscle analyzed: ICC = 0.99 for tibialis anterior; ICC = 0.99 for vastus lateralis; ICC = 1 for rectus femoris. The pilot analysis of its association with leg lean mass revealed a good association between the vastus lateralis MV and LLM, but this needs to be confirmed on a larger number of participants (Pearson correlation coefficient = 0.91, P = 0.03).The 2D-panoramic ultrasound system for the determination of MV was reliable in older hospitalized patients with measurements performed on the patient's bed. MV seemed to be more correlated to LLM than muscle thickness. Future research will need to reduce the data processing time maybe with automation of data measurement.

二维全景超声系统测定老年住院患者肌肉体积的可靠性

摘要：B型超声波评估肌肉厚度的可靠性已在成人中得到证实，但与肌肉体积（MV）相比，B型超声波仍无法直接评估肌肉质量。这项前瞻性单中心研究的目的是评估老年住院患者通过二维全景超声波测定的肌肉体积的日间可靠性。使用类内相关系数（ICC）评估的肌肉重量的日间可靠性非常好，无论分析的是哪块肌肉：胫骨前肌的 ICC = 0.99；股外侧肌的 ICC = 0.99；股直肌的 ICC = 1。对其与腿部瘦体重的关联性进行的试验分析表明，阔肌MV与LLM之间存在良好的关联性，但这还需要在更多的参与者身上得到证实（皮尔逊相关系数=0.91，P=0.03）。与肌肉厚度相比，MV 与 LLM 的相关性似乎更高。未来的研究将需要缩短数据处理时间，或许可以实现数据测量的自动化。
