Recently, ultrasound tissue characterization (UTC) was introduced as a reliable method for quantification of tendon structure. Despite increasing publications on the use of UTC, it is striking that there is a lack of normative data in active adolescents. Therefore, the aim of this study was to provide normative values of the Achilles tendon as quantified by UTC. Seventy physiotherapy students (26 male and 44 female students) with no history of Achilles tendon injuries were recruited. The Achilles tendons were scanned with UTC to characterize tendon structure. This study demonstrated that Achilles tendons of active, healthy adolescents contained 54.6% echo type I, 42.8% echo type II, 2.2% echo type III, and 0.3% echo type IV at midportion. The comparison between insertion and midportion of the tendon showed more echo type II at insertion (P < 0.001). Furthermore, female tendons contained significantly more echo type II, in both insertion and midportion compared with male tendons (P = 0.004 and P = 0.003, respectively). The results of this study, with respect to the MDC (minimum detectable change), highlight differences in the UTC echopattern in the normal population (sex and regional location), which are important considerations for future studies.
最近，超声组织特征分析（UTC）被引入作为一种可靠的肌腱结构量化方法。尽管关于UTC应用的出版物不断增加，但令人惊讶的是，活跃青少年中缺乏规范性数据。因此，本研究的目的是提供通过UTC量化的跟腱规范性值。招募了70名无跟腱损伤史的物理治疗专业学生（26名男生和44名女生）。用UTC扫描跟腱以表征肌腱结构。本研究表明，活跃、健康青少年的跟腱在中部含有54.6%的I型回声、42.8%的II型回声、2.2%的III型回声和0.3%的IV型回声。肌腱附着点与中部的比较显示，附着点处II型回声更多（P < 0.001）。此外，与男性肌腱相比，女性肌腱在附着点和中部均含有显著更多的II型回声（分别为P = 0.004和P = 0.003）。本研究关于最小可检测变化（MDC）的结果突出了正常人群中UTC回声模式的差异（性别和区域位置），这是未来研究的重要考虑因素。
