【摘要】：目的:檢測老年女性軀干穩(wěn)定性相關特征,探討其對于老年女性防跌倒的意義。方法:分別對17名有跌倒史和17名對照組老年女性,采用Pro-kin System平衡訓練儀測量軀干平衡能力和骨盆控制能力,采用DEXA測量軀干肌肉含量,采用Torso Check測量軀干肌肉力量,同時記錄腰椎活動度和進行動態(tài)平衡能力測試。運用t檢驗和pearson相關分析對實驗數據進行分析。結果:(1)跌倒組老年女性在閉眼不穩(wěn)狀態(tài)下軀干左右搖晃速度和晃動軌跡增加,兩組存在顯著性差異,骨盆控制測試用時更長;(2)軀干肌肉含量和肌力無顯著性差異,但是所有受試者均存在軀干前后、左右肌力明顯不對稱;(3)軀干肌肉含量、軀干伸肌力量、不穩(wěn)狀態(tài)下晃動軌跡面積與起立~行走測試具有低相關性。結論:(1)老年女性軀干晃動增加,尤其是左右晃動增加,骨盆控制能力下降,可能增加跌倒風險;(2)老年女性軀干肌肉含量和軀干力量改善對降低跌倒風險作用不明顯;(3)采用坐位不穩(wěn)狀態(tài)下測試可以較好地評價老年人群軀干控制能力。
[Abstract]:Objective: to investigate the characteristics of trunk stability in elderly women and its significance in preventing falls. Methods: the balance ability of trunk and pelvic control were measured by Prokin system balance training instrument, the muscle content of trunk was measured by DEXA, and the muscle strength of trunk was measured by Torso check. At the same time, the lumbar motion and dynamic balance ability were recorded. T test and pearson correlation analysis were used to analyze the experimental data. Results (1) in the fall group, the shaking velocity and trajectory of the left and right torso increased under the condition of eye closure instability, and there was a significant difference between the two groups, and there was no significant difference in the muscle content and muscle strength of the trunk between the two groups, and the pelvic control test time was longer than that in the control test (2) the muscle content and muscle strength of the trunk were not significantly different between the two groups. But all the subjects had significant asymmetry of left and right muscle strength before and after torso. The muscle content of trunk, the strength of trunk extensor muscle and the area of wobble track in unstable state had low correlation with standing up and walking test. Conclusion 1) the torso sloshing increased, especially the left and right sloshing increased, and the pelvic control ability decreased. It is possible to increase the risk of falling. 2) the improvement of trunk muscle content and trunk strength in elderly women has no obvious effect on reducing the risk of falling. 3) the ability of trunk control in elderly population can be better evaluated by using the test under the condition of unstable sitting position.
