肌少症患者的静态平衡功能及稳定极限能力分析

Static balance and limits of stability in patients with sarcopenia

目的探讨肌少症患者平衡功能的临床特征,为今后康复治疗工作提供指导。方法选取肌少症患者123例作为肌少症组,同时选取门诊收治的同年龄段健康老年人群130例作为对照组。对两组受试者进行摆动有效面积、摆动路径长度、平均摆动速度及稳定极限范围(LOS)值测试。结果 (1)无论睁眼还是闭眼,两组受试者摆动有效面积、摆动路径长度、平均摆动速度比较差异均有统计学意义(均P<0.05);与睁眼时比较,闭眼时两组受试者的上述指标均明显增大(均P<0.05)。(2)与对照组比较,肌少症组前、后、左、右方及总LOS值均明显为小(均P<0.05)。组内比较,后方LOS值较其他方向的LOS值均明显为小(均P<0.05);而前方LOS值较其他方向的LOS值均明显为大(均P<0.05)。结论肌少症患者保持平衡的能力下降,视觉训练可有助于平衡的维持;且肌少症患者LOS值减小,不利于平衡的维持。

Objective To analyze the static balance and limits of stability in patients with sarcopenia, and to provide guidance for future rehabilitation treatment. Methods One hundred and twenty three patients with sarcopenia in the community were enrolled in the study, and 130 healthy subjects of the same age were selected as the control group. The static balance and the limits of stability of all the participants were evaluated by a force platform. Results There was significant difference in static balance of the two groups in either the eyes-open or eyes-closed situation(P<0.05). In addition, when eyes were closed, these indicators were significantly increased in both groups, and there were significant difference within the group. Compared with the control group, the limit of stability was significantly lower in patients with sarcopenia(P<0.05). Conclusion The postural stability decreases in patients with sarcopenia. Visual training is needed to keep postural stability. The limit of stability is significantly lower in patients with sarcopenia, which is not conducive to the maintenance of balance.
