Abstract

Background

Poor postural control has been reported in people with Parkinson's disease, which could be explained by the changes in muscular activation patterns related to antigravitational muscles. This study aims to measure the muscle activation of antigravitational muscles during balance tasks in individuals, with and without Parkinson's.

Methods

Sixteen (16) participants (9 with Parkinson's), aged ≥65 yrs., performed 2 × 30-s trials of 4 balance tasks (bipodal and semi-tandem opened eyes and closed eyes) on a force platform (center of pressure measurement); while surface electromyography measurements were obtained bilaterally on the multifidus at L5, biceps femoris and medialis gastrocnemius. Electromyography amplitude analysis was processed by the Root Mean Square (250 ms window epochs) and normalized by the peak of activation during the balance task, to determine each muscle's activity level.

Findings

The Parkinson's group reported lower muscle activation than control across tasks (in mean for multifidus = 8%, biceps femoris = 16%, gastrocnemius = 7%), although not statistically significant. Parkinson's reported significantly poorer postural control than control, mainly for the center of pressure sway ellipse area (p = 0.016) from challenge balance tasks such as semi-tandem.

Interpretation

Poor postural control was confirmed in the Parkinson's group, but not significantly associated by the changes from muscle activation of trunk and lower limbs, during balance performance.

四项平衡任务中躯干和下肢肌肉激活与年龄和帕金森病相关的差异：病例对照试验研究

背景：据报道，帕金森病患者的姿势控制能力较差，这可能与反重力肌肉激活模式的变化有关。本研究旨在测量帕金森病患者和非帕金森病患者在完成平衡任务时反重力肌的肌肉激活情况：16名年龄≥65岁的参与者（9名患有帕金森症）在测力平台上进行了2×30秒的4项平衡任务试验（睁眼和闭眼的双足和半双足）（压力中心测量）；同时对双侧L5多裂肌、股二头肌和腓肠肌内侧进行了表面肌电图测量。肌电图振幅分析采用均方根（250 毫秒窗口历时）处理，并根据平衡任务中的激活峰值进行归一化处理，以确定每块肌肉的活动水平：帕金森氏症组报告的肌肉激活水平低于对照组（平均多裂肌=8%，股二头肌=16%，腓肠肌=7%），但无统计学意义。帕金森病患者的姿势控制能力明显低于对照组，主要是在挑战平衡任务（如半串联）中的压力中心摇摆椭圆区域（p = 0.016）：帕金森病组的姿势控制能力较差得到证实，但与平衡表现过程中躯干和下肢肌肉激活的变化无明显关联。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
