ABSTRACT
RESUMO Objetivo: Avaliar a presença de retroversão umeral e discinesia escapular em praticantes de tiro de laço. Métodos: Estudo transversal com 129 sujeitos. Foram avaliados a presença de discinesia, a força muscular, a amplitude de movimento, o nível de funcionalidade e a dor no ombro. Resultados: A rotação externa foi maior (p = 0,005) e a rotação interna menor no ombro dominante (p = 0,0001). O movimento rotacional total do ombro dominante foi menor, em comparação com o não dominante (p = 0,0001). A presença de discinesia escapular foi de 32,6%, predominou a discinesia do tipo II (50%). A pontuação do Spadi foi significativamente maior nos praticantes com sintomas de dor (p < 0,05). Conclusão: Os praticantes de tiro de laço demonstraram retroversão umeral no ombro dominante e prevalência alta de discinesia escapular.
ABSTRACT Objective: The objective of the present study was to evaluate the presence of humeral retroversion and scapular dyskinesis in these practitioners. Methods: This cross-sectional study enrolled 129 subjects. The state of dyskinesis, muscle strength, range of motion, level of functionality and shoulder pain were evaluated. Results: The external rotation was higher (p = 0,005) and minor internal rotation on the dominant shoulder (p = 0,0001). The total movement of the dominant shoulder was lower, compared to the non-dominant (p = 0.0001). The presence of Scapular dyskinesis was 32,6%, predominantly type II dyskinesis (50%). The Spadi score was significantly higher in those with pain symptoms (p <0.05). Conclusion: People who practice tie-down roping showed humeral retroversion on the dominant shoulder and higher prevalence of scapular dyskinesis.
RESUMEN Objetivo: el objetivo del estudio fue evaluar la existencia de retroversión humeral y discinesia escapular en las personas que practican esta actividad. Métodos: estudio transversal con 129 individuos. Se evaluaron la existencia de discinesia, la fuerza muscular, la amplitud de movimiento, el nivel de funcionalidad y el dolor en el hombro. Resultados: la rotación externa fue mayor (p = 0,005) y la rotación interna, menor en el hombro dominante (p = 0,0001). El movimiento total del hombro dominante fue menor en comparación con el no dominante (p = 0,0001). La existencia de discinesia escapular fue del 32,6%, sobre todo la discinesia de tipo II (50%). La puntuación del SPADI fue considerablemente mayor en los practicantes con síntomas de dolor (p < 0,05). Conclusión: los practicantes de tiro de lazo mostraron retroversión humeral en el hombro dominante y una elevada prevalencia de discinesia escapular.
ABSTRACT
Changes involving temporomandibular joint, masticatory musculature, and associated structures characterize temporomandibular dysfunction (TMD). The analgesic and anti-inflammatory effect produced by photobiomodulation has contributed to pain relief and functional improvement. However, the parameters to be used have not yet been well established. The aim of this study is to compare the efficacy of three different photobiomodulation dosimetries in the treatment of patients with TMD. A randomized, double-blind, placebo-controlled clinical trial with 44 subjects divided into the groups 8 J/cm2 (n = 11), 60 J/cm2 (n = 11), 105 J/cm2 (n = 11), and control (n = 11). Pain, symptom severity, and joint mobility were evaluated before and after a ten-session protocol of photobiomodulation with AlGaAs laser (830 nm), at a power density of 30 mW/cm2. The mouth opening increased in the 8-J/cm2 group from 10.49 ± 4.68 to 15.40 ± 6.43 degrees, and in the right protrusion from 9.80 ± 4.2 to 12.56 ± 5.40 degrees after the intervention protocol (p < 0.05). All groups significantly decreased pain (p < 0.05). 830-nm laser photobiomodulation was effective in reducing TMD pain and symptoms at all doses tested. Only the doses of 8 J/cm2 were effective regarding maximal opening and protrusion of the mandible.
