Abstract

Background: Post-stroke shoulder pain is one of the most common complications.

Aim: We aimed to investigate the shoulder pain-related myotonometric changes of the biceps brachii (BB) and triceps brachii (TB) muscles and emphasize the differences in viscoelastic parameters according to pain severity in subacute stroke patients.

Methods: In this cross-sectional study, 45 subacute stroke patients were allocated into the painless group (CG, n = 15), mild shoulder pain group (MiPG, n =16), and moderate shoulder pain group (MoPG, n = 14) using the Visual Analog Scale. The muscle tone, stiffness, and elasticity of BB and TB muscles were evaluated with the MyotonPro® (Myoton AS, Estonia).

Results: Tone was similar on both sides in all groups (p > 0.05), except for the triceps in the painless group. The tone of TB muscle was higher on the affected side in the CG (p = 0.041). BB and TB tones were lower in the pain groups compared to CG (p < 0.05). BB stiffness was higher on the unaffected side in MiPG and CG (p = 0.016 and p = 0.041). BB stiffness was also higher in the CG compared to patients with shoulder pain on both sides (p = 0.001, p = 0.044). TB stiffness was similar across all groups (p > 0.05). TB elasticity was higher on the unaffected side in MiPG and CG (p = 0.023, p = 0.010), while BB and TB elasticity did not differ significantly between groups (p > 0.05).

Conclusions: The differences between affected and unaffected extremities in stroke patients may result from adaptations in the non-paretic limb or abnormal scapular rhythm. In contrast to common knowledge, in this study, tone and stiffness decreased as pain increased. Additionally, changes in muscle elasticity may not have occurred in stroke patients during subacute phase. CTN: NCT05920837.

卒中相关疼痛中肩近端肌肉的改变:一项肌测学研究。
背景:脑卒中后肩部疼痛是最常见的并发症之一。目的:研究亚急性脑卒中患者肩关节疼痛相关的肱二头肌(BB)和肱三头肌(TB)肌肉的肌肉测量变化,并强调其粘弹性参数在疼痛严重程度上的差异。方法:采用视觉模拟量表将45例亚急性脑卒中患者分为无痛组(CG, n = 15)、轻度肩痛组(MiPG, n =16)和中度肩痛组(MoPG, n = 14)。使用MyotonPro®(Myoton AS,爱沙尼亚)评估BB和TB肌肉的肌肉张力、僵硬度和弹性。结果:除无痛组肱三头肌外,各组双侧张力差异无统计学意义(p < 0.05)。CG患侧TB肌张力增高(p = 0.041)。与CG组相比,疼痛组BB和TB音调较低(p 0.05)。MiPG组和CG组未受影响侧TB弹性较高(p = 0.023, p = 0.010),而BB和TB弹性组间差异无统计学意义(p < 0.05)。结论:脑卒中患者患肢与未患肢之间的差异可能是由于非麻痹肢体的适应或肩胛骨节律异常所致。与常识相反,在这项研究中,张力和僵硬度随着疼痛的增加而下降。此外,肌肉弹性的改变可能不会发生在中风患者的亚急性期。卡通:NCT05920837。

期刊介绍: The Irish Journal of Medical Science is the official organ of the Royal Academy of Medicine in Ireland. Established in 1832, this quarterly journal is a contribution to medical science and an ideal forum for the younger medical/scientific professional to enter world literature and an ideal launching platform now, as in the past, for many a young research worker. The primary role of both the Academy and IJMS is that of providing a forum for the exchange of scientific information and to promote academic discussion, so essential to scientific progress.
