OA is a multifactorial condition, which predisposes elderly individuals to disabilities. Therefore, aging, especially in women, is considered to be a risk factor for the development and progression of this disease. The aging process and the presence of degenerative diseases lead to losses of strength and proprioceptive acuity. However, studies have reported conflicting results regarding the relationships between these variables. Moreover, it is unclear whether age remains an aggravating factor of these variables in individuals with knee OA.
To analyze the relationships between measures of muscular performance, proprioceptive acuity, and age in community-dwelling elderly women with knee OA.
This cross-sectional study involved 35 elderly women aged 65 years and over, who had a clinical diagnosis of unilateral or bilateral knee OA and were able to walk independently. The volunteers were tested for proprioceptive acuity (joint position sense and kinesthesia) and isokinetic muscular performance of the quadriceps and hamstrings on the isokinetic dynamometer Biodex System 3 Pro®. Descriptive statistics were carried out for all outcome variables and correlation coefficients were calculated with a significance level of α < 0.05.
No significant correlations were found between the measures of muscular performance and proprioceptive acuity. Furthermore, no significant correlations were found between age and measures of strength and proprioception.
The results suggested no significant relationships between measures of proprioceptive acuity and muscular performance of the quadriceps and hamstring muscles and, especially, no influences of age on these variables in elderly women with knee OA.
骨关节炎是一种多因素疾病，易使老年人致残。因此，衰老，尤其是女性的衰老，被认为是这种疾病发展和恶化的一个危险因素。衰老过程和退行性疾病的存在导致力量和本体感觉敏锐度的丧失。然而，关于这些变量之间的关系，研究报告的结果存在矛盾。此外，在膝关节骨关节炎患者中，年龄是否仍然是这些变量的加重因素尚不清楚。
分析社区居住的膝关节骨关节炎老年女性的肌肉表现、本体感觉敏锐度和年龄之间的关系。
这是一项横断面研究，共纳入 35 名年龄在 65 岁及以上、有单侧或双侧膝关节骨关节炎临床诊断、能够独立行走的老年女性志愿者。志愿者接受本体感觉敏锐度（关节位置感和运动觉）和等速肌肉性能测试，使用 Biodex System 3 Pro®等速测力计进行股四头肌和腘绳肌的测试。对所有结果变量进行描述性统计，计算相关性系数，显著性水平为 α < 0.05。
肌肉性能和本体感觉敏锐度的测量之间没有显著相关性。此外，年龄与力量和本体感觉的测量之间也没有显著相关性。
结果表明，膝关节骨关节炎老年女性的股四头肌和腘绳肌的本体感觉敏锐度和肌肉性能之间没有显著关系，尤其是年龄对这些变量没有影响。
