ABSTRACT
The purpose of this study was to review several kinds of checklists and statements of studies in human subjects, and to examine reporting methods in order to improve the quality of studies concerning hot springs.<br>For randomized controlled trials (RCTs), “the CONSORT Statement” (Moher et al. <i>JAMA</i> 2001) consisting of 22 terms is the most well known checklist. In addition, different versions and new checklists have been developed depending upon the content of the studies (such as intervention methods) or field of the studies. There is also “the QUOROM Statement” (Moher et al. <i>Lancet</i> 1999) for a systematic review (SR) of RCTs, “the TREND Statement” (Jarlais et al. <i>Am J Public Health</i> 2004) for nonrandomized controlled trials, “the STROBE Statement” (Elm et al. <i>Ann Inter Med</i> 2007) for observational studies, and “the MOOSE Checklist” (Stroup et al. <i>JAMA</i> 2000) as a SR of observational studies. With regard to studies on hot springs, however, terms in the checklists and the statements described above are insufficient or inappropriate because of difficulties in performing such studies in a blinded manner, and the diversity of intervention methods, such as the quellen charakter.<br>Improvement of the quality of reports is important for validation of evidence. In order to improve the quality of assessments and reports of studies on hot springs, it may be necessary to develop a unique checklist based on the above-described statements and checklists.
ABSTRACT
The purpose of this study was to clarify the relationship between frequency of bathing in a spa and at home and the characteristics of the body, blood, and lifestyle of white-collar and blue-collar male employees.<br>To recruit subjects, two baseline data for randomized controlled trials in two places in Shimane Prefecture and in Nagano Prefecture were used. In the two-month period between August and September 2006, 43 of 311 white-collar male employees aged between 30 and 57 years in the Unnan municipal office volunteered to participate in this study. Similarly, 44 blue-collar workers in Nagano Prefecture volunteered to be involved in this study as a result of an appeal for volunteers in local newspapers and public information journals published by large local enterprises from September through November 2006. A total of 87 men were subjects of this study. Items evaluated in this study with respect to physique included height, weight, body mass index, waist circumference, hip circumference, and percent of body fat. With respect to strength, they were grip strength, abdominal strength, back strength, and anteflexion. With respect to characteristics of the blood, they were serum glucose, hemoglobin A1c, fructosamine, lactic acid, total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, free fatty acid, GOT, GPT, γ-GTP, cholinesterase, natural killer cell activity, T cell, B cell, CD4+, CD8+, CD4/8 and uric acid. With respect to mood, Profile of Mood States was evaluated. With respect to lifestyle, the frequency of monthly bathing in a spa and at home was evaluated.<br>No significant correlation was revealed between frequency of monthly spa bathing and the health indices in the white and blue-collar male workers. The items that were significantly correlated (p<0.05) with frequency of monthly bathing at home were GOT (positive), CD8+ (positive), and mental stress (negative).<br>In this study, frequency of monthly spa bathing was found to have no significant correlation with the health indices.
ABSTRACT
The purpose of this study was to review randomized controlled trials of the effects of treatment in spas, thereby clarifying therapeutic effects of these treatments on individual diseases, and its healthpromoting effects.<br>A review of the PubMed database for articles that fulfilled the following eligible criteria identified the studies that were chosen for this review. Key words were “randomized controlled trial” and “spa” or “balneotherapy”. Articles were published after 1990, and written in English. No criteria were set up concerning the number of subjects, the observation period, or the kind of disease studied. The quality of individual articles was evaluated on a 13-point modified PEDro scale that was constructed by adding three terms, representing the number of subjects, the observation period, and quellencharakter to the 10-point PEDro scale.<br>A total of 18 articles were chosen. Since two of them were essentially identical in content, these two articles were counted as one. As a result, a total of 17 articles were reviewed. Seven studies were conducted in France, 3 in Germany, 3 in Israel, 2 in the Netherlands, and 1 each in Italy and in Japan. Diseases studied in these articles were mostly disorders of the locomotorium, with pain as a main symptom; rheumatism in 6 articles, osteoarthritis in 4, lumbago in 3, and Parkinson's disease, varicosis, psoriasis, and health-promotion in one each. The mean score on the 13-point modified PEDro scale was 7.5 (SD, 2.3), with a minimum score of 2 points and a maximum score of 12 points.<br>The method of intervention in the spa varied widely from study to study. In addition to balneotherapy, exercise therapy, mud pack treatment, and douche massage were employed in numerous studies. Besides the intensity of pain and the amount of anodynes consumed by patients, emotional effects, QOL, physical working capacity, and even decreases in medical expenses were monitored as indicators for evaluation of the effect of the treatments in some studies. Improvements in the indicators were always more marked in balneotherapy intervention groups than in control groups, irrespective of the diseases studied. The improvements persisted for relatively long periods. In particular, a review of the high quality articles that reported effects of balneotherapy on patients with rheumatism, osteoarthritis, or lumbago showed that effects of intervention provided only once could be expected to persist for six months. With regard to the effect of quellencharakter on diseases, no definitive conclusion was obtained. On the basis of these results, we devised a “3-layer model of evidence to be accumulated in balneotherapy”
ABSTRACT
This study attempted to clarify the effects of 3- and 6-month comprehensive health education programs based on hot spa bathing, lifestyle education and physical exercise on physique, psychological vigor, blood properties, pains in the knee and back, and mental and psychological aspects of women. We examined middle-aged and elderly women who were randomly divided into two groups and followed up until six months and one year later, respectively.<br>Spa programmers, an exercise instructor, and a dietician instructed subjects to one hour of life-style education and physical exercise (lecture on behavior modification, walking, rhythmic exercise, cooking practice, etc.) and one hour (including time for changing clothes and washing body) of a half bath (salt spring, temperature at 41.5) once a week. The program for the 3-month group (n=19) was repeated in the 6-month group (n=14).<br>The evaluation items were BMI, PWC75%HRmax (by a bicycle ergometer as aerobic capacity), blood properties (total cholesterol, HDL cholesterol, arteriolosclerotic index, uric acid, and HbAlc), profile of mood states, self-rating depression scale, subjective happiness, and pains in the knee and back.<br>Compared with pre-intervention data (26.3±3.6), the BMI decreased significantly (p<0.05) immediately after the intervention (25.7±3.5) and at the follow up six months later (25.7±3.3) in the group of 6-month intervention. In addition, the PWC75%HRmax, HbAlc, pains in the back, vigor, depression, and subjective happiness remained significantly improved (p<0.05), as measured at the 6-month follow-up. On the other hand, some of the items improved in the 3-month intervention group immediately after the intervention, but returned to nearly the same levels as those before intervention at the 1-year follow-up. Significant differences (p<0.05) were found in the PWC75%HRmax, HbAlc, and fatigue between the two groups, all of which were improved in the 6-month intervention group.<br>These results suggest that a low frequency, once-a-week intervention requires duration longer than three months to maintain the effects, and that the effects should be monitored over years for a correct assessment.
ABSTRACT
Videotape feedback reportedly improves communication skills in students learning to conduct medical interviews. We carried out a study of videotape feedback in the undergraduate training program of the department of neuropsychiatry. To evaluate the interviews, we used objective structured clinical examinations and feedback from interviewed patients. The students showed several shortcomings, such as passive investigation into symptoms, past history, family history and explanatory models; poorly expressed empathy; unclear summation; poor explanation about what interviewees should do after the interview; and infrequent use of specific probes and silence skills. Feedback from patients was more favorable than that from instructors. Because our program asking psychiatric patients to participate as interviewees seems to have both advantages and disadvantages, using simulated patients would be helpful for examining the validity of our program.
