横断面临床测量研究。测量手内在肌肉力量有助于评估手功能或治疗效果。然而，在13至20岁的青少年和年轻人中没有确定的标准值。通过使用鹿特丹手内在肌测试仪测量手内在肌力量，并确定可能影响青少年和年轻人手内在肌力量的相关因素。共131名13 ~ 20岁的受试者（男：63;女：68）完成了拇短展肌、第一骨间背侧肌（FDI）、FDI深头和第二趾蚓状肌、拇短屈肌（FPB）和小指展肌的力量测量。对每种肌肉的两次测量取平均值进行分析。自我报告的人口统计学数据被用来检查年龄，性别和身体质量指数（BMI）的手内在肌肉力量的影响。按年龄组（13岁、14岁、15-16岁、17-18岁、19-20奥尔兹）列出了每个性别类别（男性、女性）的手内在肌力的标准值。一个主要的影响性别，但不是年龄，对所有的肌肉都占主导地位，（FPB：P = .02，其他：P < .001）和非显性BMI对优势拇短展肌（P =.009）和非优势拇短展肌（P =.002）有显著影响。此外，FDI（P = 0.005）和FPB（P = 0.002）在优势侧比非优势侧更强。内在手部肌肉力量可能受到不同因素的影响，包括性别，BMI和手部优势。需要更大的样本来严格调查年龄对男女青少年和年轻人内在力量的影响。这些结果提供了参考值，并建议在临床和研究环境中评估手功能和治疗结果时应考虑的因素。建议进一步研究。六.
A cross-sectional clinical measurement study. Measuring intrinsic hand muscle strength helps evaluate hand function or therapeutic outcomes. However, there are no established normative values in adolescents and young adults between 13 and 20 years of age. To measure hand intrinsic muscle strength and identify associated factors that may influence such in adolescents and young adults through use of the Rotterdam intrinsic hand myometer. A total of 131 participants (male: 63; female: 68) between 13 and 20 years of age completed the strength measurements of abductor pollicis brevis, first dorsal interosseus (FDI), deep head of FDI and lumbrical of second digit, flexor pollicis brevis (FPB), and abductor digiti minimi. Two trials of the measurements of each muscle were averaged for analyses. Self-reported demographic data were used to examine the influences of age, sex, and body mass index (BMI) on intrinsic hand muscle strength. Normative values of intrinsic hand muscle strength were presented by age groups (13, 14, 15–16, 17–18, 19–20 year olds) for each sex category (male, female). A main effect of sex, but not age, on all the muscles on both the dominant (FPB: P = .02, others: P < .001) and non-dominant (FDI: P = .005, FPB: P = .01, others: P < .001) sides was found. A significant effect of BMI was found on dominant (P = .009) and non-dominant abductor pollicis brevis (P = .002). In addition, FDI (P = .005) and FPB (P = .002) were stronger on the dominant side than the non-dominant side. Intrinsic hand muscle strength may be influenced by different factors including sex, BMI, and hand dominance. A larger sample is needed to rigorously investigate the influence of age on intrinsic strength in male and female adolescents and young adults. The results provide reference values and suggest factors to be considered when evaluating hand function and therapeutic outcomes in both clinical and research settings. Further study is recommended.
