Low back pain (LBP) is a common symptom in classical ballet dancers, which can limit their daily activities and dance training routines. The purpose of the study was to verify the association and comparison of clinical-functional outcomes (spine flexibility and foot posture) between different levels of intensity low back pain in adolescents of classical ballet and the potential risk of chronicity using the STarT back tool.
Cross-sectional study.
78 adolescent girls who practice classical ballet were evaluated and divided into groups according to level of low back pain: mild (n = 21), moderate (n = 17), and high (n = 20), and a control group (n = 20).
Pain, flexibility of the spine (thoracic and lumbosacral), risk of chronicity for low back pain, and foot posture were assessed using the visual analogue scale, clinical tests, STarT back screening tool (SBST) questionnaire, and foot posture index (FPI), respectively.
Dancers with high-intensity low back pain showed a potential risk of chronicity by the SBST. The spine pain intensity was not different considering thoracic and lumbosacral flexibility in the sagittal plane, but was different with greater supine FPI when compared to control dancers. Mild low back pain was associated with greater supine FPI. The SBST score was associated with higher exposure time-frequency and time of dancing.
Adolescents of classical ballet with high-intensity low back pain showed a potential risk of chronicity by the SBST. The level of intensity low back pain did not influence the clinical-functional aspects of spine flexibility in the sagittal plane, but the level of intensity moderate pain promoted changes in foot posture (more supinated). The potential risk of chronicity using the SBST was also associated with higher exposure time-frequency and time of dancing, in adolescents of classical ballet.
下腰痛（LBP）是古典芭蕾舞舞者的常见症状，会限制他们的日常活动和舞蹈训练。本研究的目的是使用STarT背部工具验证古典芭蕾舞青少年不同强度下腰痛的临床功能结果（脊柱灵活性和足部姿势）之间的关联和比较以及慢性化的潜在风险。
横断面研究。
78名练习古典芭蕾舞的青少年女孩接受评估，并根据下腰痛程度分为轻度组（n = 21）、中度组（n = 17）和重度组（n = 20），以及一个对照组（n = 20）。
分别使用视觉模拟量表、临床测试、STarT背部筛查工具（SBST）问卷和足部姿势指数（FPI）评估疼痛、脊柱（胸椎和腰骶部）灵活性、下腰痛慢性化风险和足部姿势。
重度下腰痛的舞者通过SBST显示出慢性化的潜在风险。考虑矢状面胸椎和腰骶部灵活性时，脊柱疼痛强度无差异，但与对照组舞者相比，仰卧位FPI更大时存在差异。轻度下腰痛与更大的仰卧位FPI相关。SBST评分与更高的接触时间频率和舞蹈时间相关。
重度下腰痛的古典芭蕾舞青少年通过SBST显示出慢性化的潜在风险。下腰痛强度水平不影响矢状面脊柱灵活性的临床功能方面，但中度疼痛水平会促使足部姿势发生变化（更内翻）。在古典芭蕾舞青少年中，使用SBST的慢性化潜在风险也与更高的接触时间频率和舞蹈时间相关。
