RESUMO
BACKGROUND: This study measured strength of the trunk and hip, and compared Y Balance Test and Upper Quarter Y Balance Test in individuals without and with scapular dyskinesis. Strength and endurance of the scapulothoracic muscles were also assessed. METHODS: Forty-four individuals without shoulder pain were divided in 2 groups: without scapular dyskinesis (age 26.00, SD 4.10â¯years) and scapular dyskinesis (age 23.68, SD 4.20â¯years). Scapular dyskinesis was assessed by clinical observation of the scapular motion during arm elevation, and was classified as present or absent. A handheld dynamometer was used to measure the isometric strength of the trunk flexors and lateral flexors, hip extensors and abductors, lower trapezius, serratus anterior, and latissimus dorsi. Y and Upper Quarter Y Balance Tests were performed with the individual in single-limb and 3-point plank position, respectively. Endurance of the scapulothoracic muscles was assessed with the individuals in prone with the arm at 135° abduction. Independent t-test and Mann-Witney test were used for comparison between groups. A Pâ¯<â¯0.05 was considered significant. Effect sizes between groups were also calculated. FINDINGS: No differences (Pâ¯>â¯0.05) were demonstrated between groups for all variables. Moderate effect size (dâ¯~â¯0.40) was found for the trunk flexors and hip extensors, and endurance of the scapulothoracic muscles, whereas the scapular dyskinesis group showed less strength and endurance in relation to the group without dyskinesis. INTERPRETATION: Strength of the trunk flexors and hip extensors, and endurance of the scapulothoracic muscles seem to have influence in scapular dyskinesis in non-athletes without shoulder pain.

BACKGROUND: Affecting more women than men, fibromyalgia syndrome (FMS) is a rheumatic disorder characterized by chronic, diffuse and widespread musculoskeletal pain, and its pathogenesis is still unknown. Among the recommended treatments, acupuncture (for its analgesic effects) is an effective option for reducing the pain sensitivity and improving quality of life. Therefore, this study aimed to investigate whether acupuncture at tender points could effectively manage FMS. METHODS: Eight female patients, with a previous diagnosis of fibromyalgia, underwent an initial assessment involving pressure algometer measurements for pain tolerance and questionnaires [Fibromyalgia Impact Questionnaire (FIQ), Heath Assessment Questionnaire (HAQ), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI)], followed by treatment. Over a 2-month period, acupuncture was performed once per week at five tender points, located bilaterally at the occipital bone, trapezius, rhomboid, upper chest and lateral epicondyle. At the end of treatment, the participants underwent a reassessment for a final review of the applied methods. RESULTS: We observed a reduction in the pain threshold and sensitivity and improvement in the areas of anxiety and depression and quality of life, which were demonstrated using the FIQ, BDI and BAI but not the HAQ. CONCLUSION: The results demonstrated the effectiveness of tender-point acupuncture treatment on the patients' overall well-being, not only by improving quality of life, but also by reducing the pain sensitivity of FMS.
