Abstract

Background and purpose: Pelvic floor muscle activity (PFMA) in adolescents with idiopathic scoliosis (AIS) has not yet been thoroughly investigated. The objective of this study was to evaluate PFMA in patients with AIS without urinary incontinence (UI) and to compare these findings with those of age- and sex-matched healthy controls.

Methods: This cross-sectional study evaluated 15 adolescents diagnosed with AIS who did not present with UI, along with 9 healthy controls. Both groups underwent assessments that included quality of life (QoL) assessment using the Paediatric Quality of Life Inventory, and the objective measurement of Cobb angles via anteroposterior and lateral radiographs, axial trunk rotation (ATR) via a scoliometer, and PFMA via surface electromyography. Comparisons of QoL scores and objective measurement results between the patient and control groups were conducted using the Mann-Whitney U test, while correlations among these parameters were analysed using Spearman's correlation coefficient.

Results: Lower physical health (p = 0.017) and total QoL scores (p = 0.037) were observed in the patient group compared with controls. The PFMA scores during the work phase were lower in patients compared with controls (work mean, p = 0.002; maximum voluntary contraction [%MVC], p = 0.005). The work mean score of PFMA negatively correlated with thoracic Cobb angle (r = -0.558, p = 0.020) and ATR (r = -0.569, p = 0.004), and the %MVC score of PFMA negatively correlated with ATR (r = -0.437, p = 0.033). There was no significant correlation between sagittal plane curvatures and PFMA or QoL.

Discussion: PFMA was reduced in adolescents with AIS compared with healthy controls. Exploratory analyses suggested negative associations between PFMA and scoliosis severity, particularly thoracic Cobb angle and ATR. These findings suggest a potential relationship between scoliosis-related spinal deformity, trunk asymmetry, and PFMA. Therefore, PFM function may be considered in the comprehensive evaluation and rehabilitation of adolescents with AIS, although confirmation in larger studies is warranted.

青少年特发性脊柱侧凸的盆底肌活动。

背景和目的：骨盆底肌活动（PFMA）在青少年特发性脊柱侧凸（AIS）尚未被彻底调查。本研究的目的是评估无尿失禁（UI）的AIS患者的PFMA，并将这些结果与年龄和性别匹配的健康对照进行比较。方法：本横断面研究评估了15名被诊断为AIS但未出现UI的青少年，以及9名健康对照。两组均接受了评估，包括使用儿科生活质量量表评估生活质量（QoL），通过正位和侧位x线片客观测量Cobb角，通过脊柱侧弯计测量轴向躯干旋转（ATR），通过表面肌电图测量PFMA。采用Mann-Whitney U检验比较患者与对照组的生活质量评分和客观测量结果，采用Spearman相关系数分析各参数之间的相关性。结果：与对照组相比，患者组身体健康状况（p = 0.017）和总生活质量评分（p = 0.037）较低。与对照组相比，患者在工作阶段的PFMA评分较低（工作平均值，p = 0.002；最大自愿收缩[%MVC]， p = 0.005）。PFMA工作平均评分与胸Cobb角（r = -0.558, p = 0.020）、ATR （r = -0.569, p = 0.004）呈负相关，PFMA %MVC评分与ATR呈负相关（r = -0.437, p = 0.033）。矢状面曲率与PFMA、QoL无显著相关性。讨论：与健康对照相比，青少年AIS患者的PFMA降低。探索性分析表明PFMA与脊柱侧凸严重程度呈负相关，特别是胸椎Cobb角和ATR。这些发现提示脊柱侧凸相关脊柱畸形、躯干不对称和PFMA之间的潜在关系。因此，在青少年AIS患者的综合评估和康复中可以考虑PFM功能，尽管需要更大规模的研究来证实。

期刊介绍： Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
