This is a clinical trial which aims to evaluate the efficiency of massage in the reduction of occupational low back pain, and its influence on the performance of work and life activities for the nursing team. The sample consisted of 18 employees who received seven to eight sessions after their work period. From the Numerical Pain Rating Scale, significant improvements were found between the 3rd and 1st evaluations (p=0.000) and between the 3rd and 2nd (p=0.004), using the Wilcoxon test. Regarding the Oswestry Disability Index, the paired t test showed a statistical difference (p=0.02) between the baseline, with a mean of 21.33% and the second evaluation (18.78%), which was also seen between the second and third evaluation (16.67%). The score for the Handling and Transfer Risk Evaluation Scale was 18 points (medium risk). It is concluded that massage was effective in reducing occupational low back pain, and provided improvement in activities of work and life. Clinical Trials Identifier: NCT01315197.

Full title: Effect of oriental medicine music therapy on patients with Hwa-byung: a study protocol for a randomized controlled trial.

Hwa-byung, a Korean culture-bound syndrome with both psychological and somatic symptoms, is also known as 'anger syndrome'. It includes various physical symptoms including anxiety, a feeling of overheating, a sensation of pressure on the chest, heart palpitations, respiratory stuffiness, insomnia, and anxiety.Methods/designThe proposed study is a single-center, double-blind, randomized, controlled trial with two parallel arms: an oriental medicine music therapy (OMMT) group and a control music therapy (CMT) group. In total, 18 patients will be enrolled into the trial. The first visit will be the screening visit. At baseline (visit 2), all participants fulfilling both the inclusion and the exclusion criteria will be split and randomly divided into two equal groups: the OMMT and the CMT (n = 24 each). Each group will receive treatment sessions over the course of 4 weeks, twice per week, for eight sessions in total. The primary outcome is the State-Trait Anxiety Inventory (STAI), and the secondary outcomes are the Hwa-byung scale (H-scale), the Center for Epidemiologic Studies Depression Scale (CES-D), the Hwa-byung visual analogue scale (H-VAS) for primary symptoms, the World Health Organization Quality of Life scale, brief version (WHOQOL-BREF), and levels of salivary cortisol. Patients will be asked to complete questionnaires at the baseline visit (visit 2), after the last treatment session (visit 9), and at 4 weeks after the end of all trial sessions (visit 10). From the baseline (visit 2) through the follow-up (visit 10), the entire process will take a total of 53 days. DISCUSSION: This proposed study targets patients with Hwa-byung, especially those who have exhibited symptoms of anxiety. Therefore, the primary outcome is set to measure the level of anxiety. OMMT is music therapy combined with traditional Korean medicinal theories. Unlike previously reported music therapies, for which patients simply listen to music passively, in OMMT, patients actively move their bodies and play the music. Because Hwa-byung is caused by an accumulation of blocked emotions and anger inside the body, OMMT, because of its active component, is expected to be more efficacious than pre-existing music therapies.Trial registrationCurrent Controlled Trials ISRCTN11939282.
