SIH typically results from a spontaneous dural tear, often linked to connective tissue disorders, minor trauma, or repetitive spinal stress. Among dancers, especially in professional ballet, the risk of SIH may be increased by repetitive spinal hyperextension and strenuous movements. Ballet movements, such as the cambré, place significant stress on the spine, potentially leading to CSF leaks. Recognizing the signs of SIH, which often presents with orthostatic headaches and lumbar pain, is critical for timely intervention and recovery, especially in athletes like dancers where functional recovery is paramount. <b>Methods:</b> We report the case of a professional female ballet dancer who presented with severe orthostatic headache and lumbar pain after a hyperextension injury during a ballet performance. Brain magnetic resonance imaging revealed pachymeningeal enhancement and a CSF fistula at the T11 level, confirming a diagnosis of SIH. Conservative treatment, including bed rest, high fluid intake, and caffeine failed to relieve symptoms. Multiple blind blood patches and a fluoroscopically targeted patch were also unsuccessful. <b>Results:</b> Definitive management was achieved via epidural patching with fibrin glue, which corrected the dural defect. A specialized physical therapy regimen focusing on spinal stabilization, core strengthening, and gradual reintroduction of dance-specific movements was essential for her recovery. This approach aimed to reduce the risk of recurrence and safely transition the patient back to dance. <b>Conclusion:</b> SIH can result from hyperextension injuries in dancers, underscoring the importance of early diagnosis and multidisciplinary management. While conservative measures may fail in some cases, surgical correction, followed by a targeted rehabilitation program, plays a crucial role in full functional recovery. A rehabilitation program tailored to the demands of professional dancing is essential to minimize long-term complications and support a safe return to performance.</p>","PeriodicalId":46421,"journal":{"name":"Journal of Dance Medicine & Science","volume":" ","pages":"1089313X251332726"},"PeriodicalIF":1.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143990921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten-sao, a fundamental practice movement in Khon masked dance, involves symmetrical continuous movements where dancers perform strong stomping actions. <b>Objectives:</b> to compare ground reaction forces (GRFs) and calculate the absolute symmetry index (ASI) between dominant and non-dominant legs during Ten-sao in Khon masked dancers. <b>Methods:</b> Fifteen healthy male Khon masked dancers with at least 5 years of experience participated in the study. Each dancer performed Ten-sao continuously for 10 cycles. The GRFs of each leg were assessed using two force plates, capturing in the vertical, antero-posterior, and medio-lateral directions during different phases of the Ten-sao dance. The ASI was calculated to assess symmetry in GRF distribution. <b>Results:</b> A significant difference in vertical GRF was found during the single-leg stance phase, with the dominant leg exhibiting greater force than the non-dominant leg (<i>P</i> = .023). The median and interquartile range (IQR) for the dominant leg was 90.005 N/kg (IQR 9.73), while the non-dominant leg exhibited a median of 57.494 N/kg (IQR 8.401). These findings highlight the asymmetry in force production between the dominant and non-dominant legs. The ASI showed asymmetries in the antero-posterior direction during double-leg support (DLS), and in the antero-posterior and medio-lateral directions during peak GRF (pGRF). Further asymmetries were observed in the antero-posterior, medio-lateral, and vertical directions during single-leg standing (SLS). <b>Conclusion:</b> The study reveals significant leg asymmetry in vertical GRF between the two legs among Khon dancers performing Ten-sao. The dominant leg demonstrates higher vertical force during SLS, and various asymmetries are presented in both DLS and SLS phases. Addressing these asymmetries in training programs is crucial for enhancing performance and reducing injury risk for Khon masked dancers.</p>","PeriodicalId":46421,"journal":{"name":"Journal of Dance Medicine & Science","volume":" ","pages":"1089313X251332329"},"PeriodicalIF":1.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The foot pressures in a pointe shoe were measured with pressure-sensitive film for 4 ballet dancers, and each dancer was measured twice.

Robust surveillance systems are required to understand and mitigate this injury risk. Current systems exhibit limitations and lack uniformity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A Delphi panel of 35 stage 1 experts were recruited through snowball sampling from online professional networks, professional dance associations, organizations, and academies. Inclusion criteria were ≥18 years of age, fluent in English, and worked as dance academics or researchers, clinicians, instructors, managers, or competitive or professional dancers. These stage 1 experts were provided with a preliminary outline of a dance injury surveillance system that covered 6 domains: dancer demographics and screening, exposure monitoring, injury identification and classification, injury management, dancer recovery and system access. Stage 1 experts then voted on the importance of and provided feedback on different design elements within each domain across 2 Delphi survey rounds to determine a consensus system design outline. A pilot system was then developed and evaluated by stage 2 experts, who were end-users and included dance instructors and administrators from various dance academies/institutions recruited through direct invitations.

Whilst data is available as to the sensitivity of strength tests for detecting changes in athlete populations, between-session reliability for adolescent ballet dancers is yet to be determined. This study aimed to determine the between-session reliability of physical performance tests in elite adolescent ballet dancers. <b>Methods:</b> Depending on the test, a cohort of 25 to 54 pre-professional ballet dancers (9 -30 males, 14-29 females) participated in a series of 6 physical tests across 12 sessions. Each testing session involved performing 1 strength test, with retesting administered 7 days later. The testing protocol included single-leg isometric squat, single-leg isometric plantarflexion, countermovement jump, standing single-leg countermovement jump, drop jump from 30 cm, and for males, seated overhead press to voluntary failure using 30 kg.
