Abstract

Background and purpose: While patients with musculoskeletal disorders reported postural balance impairments, it is unknown whether patients with piriformis muscle syndrome (PMS) may exhibit postural balance disorders compared to controls. The aim was to compare postural balance in patients with PMS to controls in static and dynamic conditions.

Material and methods: Twelve patients with PMS and twelve controls were enrolled. Static postural balance was assessed by calculating the symmetry index (SI) in the unipedal posture. To measure vision contribution, the Romberg index (RI) was computed. Dynamic postural balance was evaluated with the Timed up and go test (TUGT). Besides, inter-limb strength asymmetry (SA), pain and the short form-36 (SF-36) were assessed.

Results: The PMS group (PMSG) exhibited significant (p < 0.001) higher SI in eyes opened (EO) and eyes closed (EC) conditions compared to the control group (CG). Besides, PMSG had significant higher RI (p < 0.05), TUGT scores (p < 0.001), SA values (p < 0.05), pain intensity (p < 0.001), and worse SF-36 scores on all physical health (p < 0.05) and psychological health (only in vitality and mental health [p < 0.05]), compared to CG.

Conclusion: Our data revealed impaired static and dynamic postural balance, and reduced quality of life in PMSG compared to CG. Postural balance impairments could explain the poor quality of life, which are likely due to the higher SA and higher pain intensity. Clinicians and physiotherapists should consider postural balance disorders while designing rehabilitation programs in these patients.

梨状肌综合征会损害姿势平衡吗?病例对照研究。

背景和目的:虽然肌肉骨骼疾病患者有体位平衡障碍的报告，但与对照组相比，梨状肌综合征(PMS)患者是否会表现出体位平衡障碍尚不清楚。目的是比较经前症候群患者在静态和动态条件下的姿势平衡。材料与方法:纳入12例经前综合征患者和12例对照组。通过计算单足姿势的对称指数(SI)来评估静态姿势平衡。为了衡量视力贡献，计算Romberg指数(RI)。动态体位平衡评估与时间up和go测试(TUGT)。此外，还评估了肢间力量不对称(SA)、疼痛和短表-36 (SF-36)。结果:PMSG组(PMSG)表现出显著的(p p p p p p p p p p p p p结论:我们的数据显示，与CG相比，PMSG组的静态和动态姿势平衡受损，生活质量下降。体位平衡障碍可以解释生活质量差，这可能是由于较高的SA和较高的疼痛强度。临床医生和物理治疗师在设计这些患者的康复方案时应考虑到姿势平衡障碍。

期刊介绍： Somatosensory & Motor Research publishes original, high-quality papers that encompass the entire range of investigations related to the neural bases for somatic sensation, somatic motor function, somatic motor integration, and modeling thereof. Comprising anatomical, physiological, biochemical, pharmacological, behavioural, and psychophysical studies, Somatosensory & Motor Research covers all facets of the peripheral and central processes underlying cutaneous sensation, and includes studies relating to afferent and efferent mechanisms of deep structures (e.g., viscera, muscle). Studies of motor systems at all levels of the neuraxis are covered, but reports restricted to non-neural aspects of muscle generally would belong in other journals.
