Abstract：
(1) Background: This study investigated the relationship between weather conditions, diurnal patterns, and total knee range of motion (ROM), as well as the severity of symptoms (pain and stiffness) in older adults with knee osteoarthritis. (2) Methods: An exploratory longitudinal study was conducted on 28 older adults with knee osteoarthritis (mean age 71.86 ± 4.49 years; 46.4% men, 53.6% women). We used as assessment tools the Visual Analog Scales (VAS) for self-reported local knee pain and stiffness, and goniometry for ROM. Measurements were taken twice, six months apart, in winter and summer, in the morning and evening of each selected day. Recorded weather factors comprised temperature, relative humidity, barometric pressure, and maximum wind speed. (3) Results: The study revealed significant effects of season and time of day on pain and stiffness, respectively (p < 0.001). Additionally, a significant interaction between season and time influenced total knee ROM (p < 0.001). Moreover, there was a statistically significant relationship between time and total knee ROM (p < 0.001). (4) Conclusions: This research underscores the complex link between seasonal fluctuations and daily variations in some symptomatic and functional aspects of knee osteoarthritis in older adults.
摘要：
(1)背景：本研究调查了天气状况之间的关系，昼夜模式，和膝关节总运动范围(ROM)，以及症状的严重程度（疼痛和僵硬）在老年人膝骨关节炎。（2）方法：对28名患有膝骨关节炎的老年人进行了探索性纵向研究（平均年龄71.86±4.49岁；男性占46.4％，53.6%妇女)。我们使用视觉模拟量表（VAS）作为评估工具，用于自我报告的局部膝关节疼痛和僵硬，和ROM的测角法。测量了两次，相隔六个月,在冬天和夏天，在每个选定的日子的早晨和晚上。记录的天气因素包括温度，相对湿度,大气压力,和最大风速。（3）结果：研究显示季节和时间对疼痛和僵硬有显著影响，分别(p<0.001)。此外,季节和时间之间的显着相互作用影响了膝关节总ROM（p<0.001）。此外，时间与膝关节总ROM之间存在统计学上显著的关系(p<0.001)。（4）结论：这项研究强调了老年人膝骨关节炎的某些症状和功能方面的季节性波动和日常变化之间的复杂联系。
