Dynamic balance devices are costly and uncommon, requiring dedicated space for use. Thus, studies often utilize smartphones to measure dynamic balance by attaching them to body parts, as they are inexpensive, small, and readily available. However, little consideration has been given to determine which body part would yield the most reliable measurements.
ː A total of 25 healthy college students consented to stand on a balance pad on their dominant leg for 30 s. The test and retests were performed at a one-week interval.
ː Agreement between the test and retest values was moderate for those obtained from the sternum and waist (0.50 ≤ ICC ≤ 0.74) and was good for those obtained from the shin (0.75 ≤ ICC ≤ 0.89). There were significant moderate positive correlations between the test and retest results for all the attachment sites (0.40 < r < 0.69, p < 0.05).
Based on a review of related literature and the experiment's results, this study determined the pros and cons of using a smartphone as a measuring tool and the various measurement locations in the body. Despite the smartphone being a low-cost measuring tool, greater care must be taken to ensure the validity of the interpreted data.
ː Although quantifying balance is necessary for evidence-based medicine, clinics seldom use existing modern devices due to their costliness. This study's results suggest that a smartphone, which is a cheaper alternative, produces the most reliable results when attached to the shin.
动态平衡设备价格昂贵且不常见，需要专门的空间使用。因此，研究通常使用智能手机通过将其附着在身体部位上来测量动态平衡，因为它们价格低廉、体积小且易于获得。然而，很少有人考虑确定哪个身体部位会产生最可靠的测量结果。
共有 25 名健康的大学生同意用他们的优势腿在平衡垫上站立 30 秒。测试和复测在一周的间隔内进行。
胸骨和腰部（0.50≤ICC≤0.74）获得的测试值与复测值之间的一致性为中度，胫骨（0.75≤ICC≤0.89）获得的测试值与复测值之间的一致性良好。所有附着部位的测试值与复测值之间均存在显著中度正相关（0.40<r<0.69，p<0.05）。
根据对相关文献的回顾和实验结果，本研究确定了使用智能手机作为测量工具和身体各个测量部位的优缺点。尽管智能手机是一种低成本的测量工具，但必须更加小心，以确保解释数据的有效性。
虽然基于证据的医学需要量化平衡，但由于成本高昂，诊所很少使用现有的现代设备。本研究的结果表明，智能手机是一种更便宜的替代方案，当附着在胫骨上时，它会产生最可靠的结果。
