摘要

脊髓和球肌萎缩症(SBMA)是一种神经肌肉疾病,导致球和四肢肌肉进行性无力。功能性任务中的动态平衡尚未在SBMA患者中报道。目的:(1)评估安全完成前弓步(FL)、跨步快速转身(SQT)和上跨(SUO)的能力;(2)通过将表现与规范数据进行比较,确定动态平衡障碍的存在和严重程度;(3)研究下肢力量与完成各项任务能力之间的关系。设计:横断面分析。参与者。53名SBMA患者被纳入横断面分析。NeuroCom制造商提供的规范数据集和等长强度文献便于患者比较。结果的措施。基于力板的动态平衡测量包括FL(距离、冲击指数、接触时间和力脉冲)、SQT(转弯时间和转弯摆动)和SUO(上升指数、运动时间和冲击指数)。用固定式测力仪测量膝关节伸肌、踝关节背屈肌、足底屈肌和髋关节伸肌的最大等距收缩。结果:按完成率计算,最难的是SUO(52%),其次是FL(57%)和SQT(65%)。t检验显示,9个平衡变量中有8个存在显著异常(p < 0.05),且Cohen's D效应值≥0.8。受试者操作特征分析显示,膝关节伸肌(SUO 95%CI =0.78-1.00, SQT 95%CI =0.64-0.92)和踝关节足底屈肌力量(SUO 95%CI = 0.75-0.99, SQT 95%CI =0.64-0.92)显著区分了曲线下可接受到优秀区域的SUO和SQT测试的能力。结论:观察到相当多的动态平衡异常。下肢强度有助于解释较低的测试完成率。患者修改了任务运动模式,使任务表现安全。研究结果可以帮助指导SBMA患者的护理和未来的方案设计。

Dynamic Balance in Spinal and Bulbar Muscular Atrophy: Relationship between Strength and Performance of Forward Lunge, Step Up and Over, and Step Quick Turn.

Introduction: Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disorder that leads to progressive weakness of bulbar and extremity muscles. Dynamic balance during functional tasks has not been reported in people with SBMA.

Objectives: (1) To evaluate the ability to safely complete a forward lunge (FL), step quick turn (SQT), and step up and over (SUO), (2) to determine the presence and severity of dynamic balance impairments by comparing performance to normative data, and (3) to investigate the relationship between lower extremity strength and ability to complete each task.

Design: Cross-sectional analysis. Participants. Fifty-three people with SBMA were included in a cross-sectional analysis. Normative datasets provided by the NeuroCom manufacturer and isometric strength literature facilitated patient comparisons. Outcome Measures. Force plate-based dynamic balance measures included FL (distance, impact index, contact time, and force impulse), SQT (turn time and turn sway), and SUO (lift up index, movement time, and impact index). Maximal isometric contractions of knee extensors, ankle dorsiflexors, ankle plantar flexors, and hip extensors were measured with fixed frame dynamometry.

Results: The most difficult test, per completion rate, was SUO (52%), followed by FL (57%) and SQT (65%). t-tests revealed significant abnormalities in eight of nine balance variables (p < 0.05) accompanied by large Cohen's D effect sizes ≥ 0.8. Receiver operating characteristics analysis showed knee extensor (SUO 95% CI =0.78-1.00, SQT 95% CI =0.64-0.92) and ankle plantar flexor strength (SUO 95%CI = 0.75-0.99, SQT 95%CI = 0.64 - 0.92) significantly discriminated the ability to perform SUO and SQT tests with acceptable to excellent areas under the curve.

Conclusions: Considerable dynamic balance abnormalities were observed. Lower extremity strength helps explain low test completion rates. Patients modified task movement patterns, enabling safe task performance. Study results can help direct patient care and future protocol design for people with SBMA.
