Effectiveness of aides in a perceptual motor training program for children with learning disabilities.

A program for children with learning disabilities associated with perceptual deficits was designed that included elements of gross and fine motor coordination, visual and somatosensory perceptual training, dance, art, music and language. The effectiveness of nonprofessional "perceptual-aides," who were trained in this program, was evaluated. Twenty-eight children with learning disabilities associated with perceptual deficits were treated by occupational, physical, recreational and language therapists; and 27 similarly involved children were treated by two aides, under supervision, after training by therapists. Treatment in both groups was for four hours weekly over a four to seven month period. There was significant improvement in motor skills, visual and somatosensory perception, language and educational skills in the two programs. Although there was no significant difference between the two groups, there was a slight advantage to the aide program. The cost of the aide program was 10 percent higher than the therapist program during the first year, but 22 percent lower than the therapist program during the second year.

[Selected indices of nutritional status and food habits among young ballet dancers].

The work has been aimed at assessment of nutritional status on the base of some selected anthropometric factors and at evaluation of food habits among schoolchildren of the ballet dance school at Gdańsk. The 58 boys and girls were examined. The height, body mass and body fat were measured, and the Body Mass Index values calculated. The results were compared to those obtained among children at Poznań and Kielce. The survey of food habits was made with the especially prepared questionnaire. The substantial deficiency of body fat and relatively low body mass were observed. The BMI value below 18 was found for 35% of subjects, and between 20 and 25 only for 23% of subjects. The wrong food habits were found, especially low number of meals and their irregular consumption.

[Eurhytmy by Steiner].

According to Rudolph Steiner the aim of medical anthroposophy must be to revalue the soul-body intercourse as a function of recovery. To this purpose, along with mineral, organic and vegetable medicinal principles, of a particular importance is eurhythmy: a series of static postures and dancing shapes which encourage the course of selfeuring innate with man.

Joint laxity and the benign joint hypermobility syndrome in student and professional ballet dancers.

OBJECTIVE: To ascertain the prevalence of hypermobility and the benign joint hypermobility syndrome (BJHS) in male and female student and professional ballet dancers, and explore whether BJHS has any effect on a dance career. METHODS: Students from the Royal Ballet School and professional dancers from the Royal Ballet Company, London, were compared with a control group of teenagers and adults from a local secondary school and The Royal Opera House, respectively. The data, examined by variance analysis, included anthropometric variables, the Beighton score, and clinical features constituting BJHS. Odds ratios for hypermobility and BJHS in dancers were calculated, and the prevalence and distribution of BJHS was examined. RESULTS: Hypermobility and BJHS were common in male and female dancers compared with controls. An OR of 11.0 (95% CI 3.3-31.8) was found for hypermobility in dancers for both the ballet school and the professional company. The prevalence of BJHS was found to decline both from student to professional and within the ballet company from corps de ballet to Principal. Odds ratios for BJHS in student dancers were significant, OR = 3.9 (95% CI 1.3-11.3), but not so in professional dancers: OR = 1.7 (95% CI 0.6-4.7). Arthralgia was common in dancers and was reported more often in males than females. In females, pain was reported most by dancers with other features of BJHS, in particular stretchy skin. CONCLUSION: Hypermobility and BJHS are common in both male and female student and professional ballet dancers. The fall in prevalence, and the greater reporting of arthralgia with other features of BJHS in young female dancers, suggests that BJHS may have an important negative influence, and this may have implications for training. The same pattern was not observed in males, suggesting that their pain-reporting and injury are related to factors other than BJHS.

[A study of psychiatric patients perceived effect and expectancy of activity therapy].

The intent of this descriptive study is to investigate the patients perceived effect and expectance of activity therapy. The subjects for this study were 56 patients from the psychiatric ward in Severance Hospital. The data were collected during the period from June 1, 1991 to January 18, 1992. The effect and expectance of the activity therapy was measured using a questionnaire developed by this study's investigators. The date were analyzed by descriptive statistics, t-test and one-way ANOVA, using the SPSS program. The results of this study can be summarized as following; 1. For motivation for the activity therapy, the response range was from 64.3% to 89.3%, that is, it showed a relatively positive response. 2. For the degree of improvement according to the nurse's method in the activity therapy, it was shown that the nurses need professional skill and meeting after activity therapy. 3. For the relevance of the nurse in the activity therapy, 90% of the subjects had a positive answer for all of the activity therapy except the painting therapy. 4. For the perceived effect of the activity therapy, the following results were obtained. 1) 92% of the subjects had a positive response to the dance therapy, that is-I am vigorous physically. 2) 90% of the subjects had a positive response to the reading therapy, that is-I acquire good ideas and instruction. 3) 98.1% of the subjects had a positive response to the recreation therapy, that is-I am joyful. 4) 88.9% of the subjects had a positive response to the writing therapy, that is-I am interested and become acquainted with other patients. 5) 86.8% of the subjects had a positive response to the occupation therapy, that is-I am happy when I work. 6) 92.6% of the subjects had a positive response to the painting therapy, that is-I can express myself in painting. 7) 87.3% of the subjects had a positive response to the music therapy, that is-I am comforted. 5. For the expectance related to the activity therapy, 97.1% of the subjects had the most positive response to the music therapy which is a pleasant comfortable time. From the above-mentioned findings, it is suggested that psychiatric nurses need to development systematic and professional group activity therapy, and know the patient premorbid hobbies, interests and occupations.

Sudden death associated with food and exercise.

Exercised-induced anaphylaxis occurs in conjunction with significant physical exertion. Anaphylaxis occurring when an individual exercise within a few hours of ingesting a particular food is an unusual variant. Cardiovascular symptoms can be the sole manifestation of exercise-induced food allergies, in which case death may mimic sudden cardiac death during physical exertion due to other pathologic causes. We report the sudden and unexpected death of an individual following the ingestion of hazelnuts and almonds, to which the individual was not previously known to be allergic. The decedent collapsed during vigorous dancing. The death was not associated with cutaneous or laryngeal manifestations of anaphylaxis. Awareness of the variable manifestations of food-precipitated anaphylaxis is necessary to correctly establish the diagnosis. An elevated serum tryptase level may be indicative of an allergic reaction, and allergen-specific IgE levels may be used to confirm the particular antigen.

Body composition in ballet dancers measured by total body electrical conductivity.

The purpose of this study was to describe the body composition of adolescent and young adult ballet dancers using total body electrical conductivity (TOBEC). We studied 112 female and 33 male dancers. The mean ages were 15.0 +/- 2.0 and 18.7 +/- 3.1 yr for females and males, respectively. The mean percent body fat (PBF) values were 20.1 +/- 3.6% for the females and 14.5 +/- 4.2% for the males. Age and pubertal development were not significantly related to PBF in the females. Age and pubertal status were significantly inversely related to PBF in the males. There was no difference in dance history, percent body fat, and abdominal/hip or waist/hip ratios in eumenorrheic vs amenorrheic dancers. Estimated calorie intake indicated that dancers with menstrual abnormalities had lower calorie intake than those with normal menses. This is the largest group of ballet dancers whose body composition has been studied. Our PBF measurements are higher than in previous reports using hydrodensitometry, which may have underestimated body fat by not accounting for the increased bone density in the lower extremities of dancers. Our data suggest that previous measurements of PBF in dancers are underestimates; these new data challenge our concept of PBF values in dancers.

Effect of ballet on immunity in young people.

The peripheral blood samples obtained from 32 ballet students with a mean age of 17.5 years and 32 age-matched non- dancers who comprised a control group were analysed using the microdeterminations of lymphocyte blast transformation and mixture rosette forming cells. The percentage of lymphocyte blast transformation of ballet students was normal, but their percentage of E-rosette forming cells was lower than that of controls at rest. A significant increase in the percentage of zymosan-complement rosette forming cells was seen during dancing. The study suggests that a saving effect on expenditure of cellular immunofunction is exhibited in ballet students at rest and that intensive ballet-exercise induces an immediate humoral immune response change. However, the effect needs to be dynamically observed and the clinical implication of the response change remains to be proved.

Anthropometric measurements of adolescent and professional classical ballet dancers.

This study examined anthropometric measures of 83 female adolescent students attending the Boston Ballet summer program and 15 professional dancers from the Boston Ballet Company. Thirty-one were in the least advanced level (group A), 38 were in the moderately advanced level (group B) and 14 were in the most advanced level (group C). The adolescent dancers devoted between 17 and 23 hours per week in dance training, while professional dancers spent 39.2 hours per week in class and rehearsals. Compared to normative data, the dancers tended to be tall and slim. The skinfold, diameter, and circumference measurements were found to be very similar among groups A, B and C, and between group C and the company members. The somatograms demonstrated that the ballet dancers had relatively smaller upper arms and larger calves and ankles compared with the reference female. The data from this study suggest that the body type characteristics associated with professional classical ballet dancers are already apparent in the pre-professional adolescent dancers.

Occupational biomechanics of athletes and dancers: a comparative approach.

Muscle strains represent more than a third of all injuries in both dancers and athletes. Although often overlooked, anatomic variations play an important role in the etiology of these injuries, as does strength imbalance between agonists and antagonists. The incidence of spondylolysis is unusually high in ballet dancers and certain athletic groups, such as gymnasts, javelin throwers, and weight-lifters. Mechanical factors play a major role and can be exacerbated by congenital abnormalities. Various permanent adaptive musculoskeletal changes have been described both in dancers and athletes, especially those that start at a very young age. Task-related adaptive changes can also be seen in isokinetic strength measurements of various muscle groups, such as the spine muscles of Flamenco dancers. Shoes and floor surfaces can be directly responsible in part or in whole for many sports and dance injuries. "Vibration-pressure" diagrams are suggested as an objective way to document their effect on biomechanical behavior.

Relationship between nutrient intake, body mass index, menstrual function, and ballet injury.

The effects of inadequate nutrition, menstrual dysfunction, and low body weight on the injury rate of ballerinas were studied. Forty-nine female ballet dancers, mean age 18.7 years, completed food frequency and injury questionnaires. Subjects were placed in one of two groups: those with an intake less than 70% of the Recommended Dietary Allowances (RDA) for key nutrients and those with an intake greater than 70% of the RDA for key nutrients. Sixty-nine percent of the dancers had intakes less than 70% of the RDA and were randomly assigned to either a vitamin/mineral supplement or to placebo for 6 months. The remaining dancers with diets adequate (greater than 70% RDA) in key nutrients received no treatment. All groups were questioned monthly about the incidence, severity, and nature of ballet injuries. Information regarding menses and height and weight was obtained. There were no significant differences in the severity or type of injuries among the dancers in the supplement, placebo, or no treatment groups. Dancers with abnormal menses had more bone injuries (mean = 15.00) than normally menstruating dancers (mean = 4.97) (p less than .05). Dancers with a Body Mass Index less than 19.0 spent more days with a low-grade injury (mean = 24.05) than dancers with a greater BMI (mean = 11.63) (p less than .05). There appears to be a relationship between dance injuries and both BMI and menstrual function.

The role of selectivity in the pathogenesis of eating problems in ballet dancers.

Forty-nine dancers from four national ballet companies in America (N = 32) and the People's Republic of China (N = 17) were surveyed (mean age, 24.6 +/- 4.18) from highly and moderately selective dance companies. The less selected American dancers reported significantly more eating problems (46% vs 11%; P less than 0.05), anorectic behaviors (2.77 vs 1.11; P less than 0.05), and familial obesity (42% vs 5%; P less than 0.05) than the Americans chosen from a company school. Differences were not found on these variables between the highly selected American and Chinese dancers. All of the groups reported a delay in menarche and weighed approximately 14% below their ideal weight for height. These data suggest that dancers who have survived a stringent process of early selection may be more naturally suited to the thin body image demanded by ballet and so less at risk for the development of eating problems. In addition, delayed menarche is typical of the majority of national dancers and probably is reflective of genetic and environmental factors.

Dietary intake and symptoms of anorexia nervosa in female university dancers.

This study was designed to measure and evaluate the dietary intake and symptoms of anorexia nervosa in female university dancers (no. = 21) and a control group of female university non-dancers (no. = 29). Three-day food records were analyzed for calories, protein, vitamin A, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, and iron. Symptoms of anorexia nervosa were determined through the use of an objective questionnaire, the Eating Attitudes Test (EAT). The percent of subjects who consumed less than two-thirds of the Recommended Dietary Allowance (RDA) for energy was significantly higher in the dance group (28.6% vs. 10.3%, p less than .005). Seventy percent of the total study population consumed less than two-thirds of the RDA for at least one nutrient, and 24% consumed less than two-thirds of the RDA for three or more nutrients. Thirty-three percent of the dancers and 13.8% of the controls scored in the range symptomatic of anorexia nervosa on the EAT, a difference that was statistically significant (p less than .005). The results indicate that both female university dancers and female university students may be at risk for nutrient deficiency and anorexia nervosa.
