RESUMEN
Objective: In the domain of competitive events, Latin dance athletes have always suffered competitive anxiety, which is a prevalent and prevailing psychological facet, in pre-, intra-, and post-competitive engagements. Usually, the implementation of systematic desensitization training is an efficacious approach to reduce competitive anxiety levels in routine sports to fortify psychological resilience of athletes (like swimming, volleyball, and basketball). This study focuses on the effect of systematic desensitization training on competition anxiety in the training of Latin dancers to establish good mental ability and promote the competitive ability of athletes. Methodology: The "Sports Competition Anxiety Test Questionnaire" was used to evaluate and classify the competitive anxiety levels of 150 Latin dance athletes. Then, the top 48 participants were selected (24 in the intervention cohort and 24 in the non-intervention cohort) as the study participants after stratifying anxiety score levels from the highest to the lowest. The intervention group was treated with an 8-week psychological intervention by employing systematic desensitization training techniques (encompassing imagery desensitization and in vivo desensitization). The anxiety levels of the subjects were quantified by employing the "Sport Competition Trait Anxiety Inventory" (CCTAI-C) and the "Competitive State Anxiety Inventory" (CSAI-2) to scrutinize the efficacy of systematic desensitization training in regulating competitive anxiety levels among Latin dance athletes. Results: After applying systematic desensitization training, the intervention group displayed a notable reduction in sport cognitive trait anxiety. Specifically, there was a decrease of 29.37% in social evaluation anxiety, 20.31% in competition preparation anxiety, 16.98% in performance anxiety, 25.16% in failure anxiety, 34.47% in opponent's ability anxiety, and 25.16% in injury anxiety. Moreover, for competitive state anxiety, cognitive state anxiety and somatic state anxiety decreased by 39.19 and 21.43%. The state self-confidence increased by 14.42%. Conclusion: The result indicated that systematic desensitization training not only mitigates anxiety but also positively intervenes in sports-related anxiety. Moreover, systematic desensitization training can significantly diminish competitive anxiety among Latin dance athletes to bolster confidence during competitions. Integrating desensitization training into the regular regimen of Latin dance practice has the potential to fortify dancers' psychological resilience against anxiety.
RESUMEN
OBJECTIVE: To assess the effectiveness of oral Chinese herbal medicine (CHM) in relieving pain secondary to bone metastases in patients. METHODS: The searched electronic literature databases included both English and Chinese articles published in the MEDLINE, EMBASE, Wanfang database and China National Knowledge Infrastructure (up to December 2012). The studies included randomized controlled trials (RCTs) comparing CHM plus conventional treatment with conventional treatment alone for patients with pain secondary to bone metastases. The outcomes were the odds ratio (OR) with 95% confidence intervals (CI) for the pain-relief rate and adverse events. RESULTS: A total of 16 RCTs involving 1,008 patients were identified and analyzed. All of the included RCTs were associated with a moderate to high risk of bias. In the metaanalysis, CHM plus conventional treatment increased the pain-relief rate compared with the conventional treatment alone (OR, 2.59; 95% CI 1.95 to 3.45). In subgroup analysis, the pooled OR of the pain-relief rate of CHM plus conventional treatment compared with conventional treatment was 3.11 (95% CI 2.01 to 4.79) for CHM plus bisphosphonates, 2.24 (95% CI 1.33 to 3.78) for CHM plus analgesics, 2.28 (95% CI 1.09 to 4.79) for CHM plus radiotherapy, and 2.22 (95% CI 0.95 to 5.15) for CHM plus analgesics and bisphosphonates. The adverse events included nausea, vomiting, dizziness, fever, and constipation. No serious adverse events were reported in any of the included studies. CONCLUSIONS: CHM interventions appear to have beneficial effects on pain secondary to bone metastases in patients. However, published efficacy trials are small in size to draw any firm conclusions.
RESUMEN
OBJECTIVES: Stimulation of acupuncture points (acupoints) located on meridians has been proven to activate specific areas of the human brain, as evidenced by functional imaging studies. To date, the specificity of acupoints located on different meridians has been investigated with functional magnetic resonance image (fMRI). The present fMRI study explored the effects of stimulating 4 acupoints on 2 different meridians for the purpose of researching the characteristic response of acupoints on the same meridian. MATERIALS AND METHODS: The acupoints studied were LR3 (Taichong) and LR6 (Zhongdu), which belong to the Liver meridian of Foot-Jueyin; ST36 (Zusanli) and ST43 (Xiangu), which belong to the Stomach meridian of Foot-Yangming; and 2 nearby sham acupoints. Fifty-three (53) healthy right-handed subjects were divided randomly into 6 groups. Each group only received acupuncture at one acupoint. All the acupoints in this study were stimulated only on the right side of the subject's body. Through analysis of fMRI data from all subjects, we obtained the activation patterns in the central nervous system (CNS) evoked by acupuncture. RESULTS: In contrast to the CNS activation by sham acupoint, the results showed that all 4 real acupoints under consideration had the common effect of activating 2 specific areas of the brain: the bilateral primary somatosensory area and the ipsilateral cerebellum. Acupuncture stimulation of both acupoints LR3 and LR6 evoked activation at the ipsilateral superior parietal lobe (BA7). Acupuncture stimulation of both acupoints ST36 and ST43 evoked activation at the ipsilateral middle frontal gyrus (BA10). CONCLUSIONS: These results suggest that different acupoints on the same meridian may activate certain similar areas of the brain. In addition, acupoints that are commonly used in clinical practice might modulate a greater extent of cortical areas than uncommonly used acupoints.
