Decreased physical performance has been associated with an increased risk of falls and fragility hip fractures. The purpose of our study was to compare physical performance measures and fall risk factors in middle-aged and elderly patients with recent distal radial fractures relative to age-matched control patients.
We prospectively recruited forty postmenopausal women over fifty years of age who sustained a distal radial fracture due to a fall and forty age-matched controls without a recent history of falls. We excluded those patients with cognitive impairment, neuromuscular diseases, or other chronic conditions affecting muscle function. We compared the two groups for the level of physical performance and other risk factors of a fall. Other known risk factors assessed were low body mass index; osteoarthritis; arrhythmia; depression; visual disturbance; hypotension; use of antihypertensive drugs, sedatives, hypnotics, or antidepressants; and use of four or more medications.
There was no significant difference in the Short Physical Performance Battery summary score between the two groups. However, when patients with distal radial fracture were compared with control patients, significantly lower scores were observed for chair stand (p = 0.034) and grip strength (adjusted for hand dominance) (p = 0.038).
This study suggests that overall physical performance level is not different between women with a distal radial fracture and those without a distal radial fracture. Differences in chair stand test scores and grip strength may imply an early subtle decrease in physical performance level in patients with distal radial fracture.
身体机能下降与跌倒风险增加和髋部脆性骨折风险增加相关。我们的研究目的是比较中年和老年新发桡骨远端骨折患者与年龄匹配的无近期跌倒史患者的身体机能测量值和跌倒风险因素。
我们前瞻性招募了 40 名 50 岁以上因跌倒而发生桡骨远端骨折的绝经后女性患者和 40 名年龄匹配的无近期跌倒史的对照患者。我们排除了有认知障碍、神经肌肉疾病或其他影响肌肉功能的慢性疾病的患者。我们比较了两组患者的身体机能水平和其他跌倒风险因素。评估的其他已知风险因素包括低体重指数、骨关节炎、心律失常、抑郁、视力障碍、低血压、使用抗高血压药物、镇静剂、催眠药或抗抑郁药以及使用 4 种或更多种药物。
两组间短体功能力量测试综合评分无显著差异。然而，与对照组相比，桡骨远端骨折患者的椅上站立（p = 0.034）和握力（根据手优势调整）（p = 0.038）评分显著较低。
本研究表明，桡骨远端骨折患者与无桡骨远端骨折患者的整体身体机能水平无差异。椅上站立测试评分和握力的差异可能意味着桡骨远端骨折患者的身体机能水平早期出现轻微下降。
