BACKGROUND
Based on Davis's law, greater tonus of the muscle belly in individuals with Parkinson's disease can create greater tension in the tendon, leading to structural adjustment and an increase in tendon stiffness. Our study aimed to separately assess passive stiffness in the muscle belly and tendon in medicated patients with Parkinson's disease, using myotonometry.
METHODS
We tested 12 patients with Parkinson's disease and 12 healthy matched controls. Passive stiffness of muscle belly and tendon was estimated by myotonometry, electromyography, and mechanomyography in relaxed biceps and triceps brachii muscles.
RESULTS
Compared with controls, patients with Parkinson's disease had higher stiffness in the muscle belly and tendon of the biceps brachii and in the tendon of the triceps brachii. In patients with Parkinson's disease, there was a positive correlation between muscle belly stiffness and parkinsonian rigidity in the biceps brachii.
CONCLUSION
Patients with Parkinson's disease have higher passive stiffness of the muscle belly and tendon than healthy matched controls.
背景
根据戴维斯定律，帕金森病患者的肌腹张力增加会导致肌腱张力增加，从而导致结构调整和肌腱僵硬增加。我们的研究旨在使用肌振仪分别评估帕金森病患者药物治疗后的肌腹和肌腱的被动僵硬。
方法
我们测试了 12 名帕金森病患者和 12 名健康匹配的对照者。通过肌振仪、肌电图和运动描记法测试放松的肱二头肌和肱三头肌的肌腹和肌腱的被动僵硬。
结果
与对照组相比，帕金森病患者的肱二头肌和肱三头肌的肌腹和肌腱以及肱三头肌的肌腱僵硬度更高。在帕金森病患者中，肱二头肌的肌腹僵硬度与帕金森氏僵硬呈正相关。
结论
与健康匹配的对照组相比，帕金森病患者的肌腹和肌腱的被动僵硬度更高。
