Respiratory complications are a leading cause of mortality post spinal cord injury (SCI). Along with breathing, respiratory muscles have a role in maintaining seated balance. Postinjury breathing influences respiratory muscle function. Preliminary evidence indicates a relation between respiratory muscle function and seated balance in people with chronic SCI dwelling in the community, but the relationship between balance and body habitus has not been explored.
To explore the relationships among inspiratory muscle function, functional seated balance (FSB), and body habitus in people with SCI.
A convenience sample of inpatients with SCI (C5-T12) aged 18 to 60 years who were using a wheelchair was recruited from November 2022 to March 2023. Those with additional neurological disorders or respiratory support were excluded. Respiratory muscle function measures included maximal inspiratory pressure (MIP), sustained MIP (SMIP), and Fatigue Index Test (FIT). FSB was scored using the Function in Sitting Test (FIST). Body habitus was assessed using the axillary: umbilical (A:U) ratio. Spearman correlations explored the relationships.
Thirty-eight of 42 screened participants were eligible and participated (male, 32). Levels of injury ranged from C5 to T12. The mean () age and duration of injury of the sample was 25.61 (6.68) years and 31.03 (28.69) months, respectively. SMIP and FIT correlated significantly with FSB ( = .441, = .01, and = .434, = .006, respectively). A significant correlation between SMIP and A:U ratio ( = -.330, = .043) was observed.
We observed a significant correlation between inspiratory pressure parameters and both functional seated balance and body habitus, adding to evidence on postural role of respiratory muscles.
呼吸并发症是脊髓损伤（SCI）后导致死亡的主要原因。除了呼吸，呼吸肌在维持坐姿平衡方面也发挥作用。损伤后的呼吸会影响呼吸肌的功能。初步证据表明，社区居住的慢性 SCI 患者的呼吸肌功能与坐姿平衡之间存在关联，但平衡与身体形态之间的关系尚未得到探索。
探讨 SCI 患者的吸气肌功能、功能性坐姿平衡（FSB）和身体形态之间的关系。
本研究采用便利抽样法，于 2022 年 11 月至 2023 年 3 月招募年龄在 18 至 60 岁、使用轮椅的 SCI（C5-T12）住院患者。排除有其他神经障碍或呼吸支持的患者。吸气肌功能测量包括最大吸气压力（MIP）、持续 MIP（SMIP）和疲劳指数测试（FIT）。FSB 使用坐姿功能测试（FIST）进行评分。身体形态使用腋窝：脐部（A:U）比值评估。采用 Spearman 相关分析探讨这些关系。
在筛选出的 42 名参与者中，有 38 名符合条件并参与了研究（男性 32 名）。损伤水平从 C5 到 T12 不等。样本的平均（）年龄和损伤持续时间分别为 25.61（6.68）岁和 31.03（28.69）个月。SMIP 和 FIT 与 FSB 显著相关（=.441，=.01，和=.434，=.006，分别）。SMIP 与 A:U 比值之间存在显著相关性（= -.330，=.043）。
我们观察到吸气压力参数与功能性坐姿平衡和身体形态之间存在显著相关性，这进一步证明了呼吸肌在姿势方面的作用。
