Simultaneous and successive processes in achievement for learning disabled children.

The relationship between simultaneous and successive dimensions of the Wechsler Intelligence Scale for Children-Revised and achievement areas of the Wide Range Achievement Test were examined by means of separate multiple correlations. The results of these analyses showed that each WRAT subtest produced a significant relationship with both processing modes. Although the magnitude of the relationship was similar for simultaneous and successive dimensions, a more consistent WRAT contribution was found for successive processing. A canonical correlation was utilized to consider the relationship between simultaneous and successive processing and achievement subtests in a single analysis. One significant correlation emerged from this procedure, Rc = 0.45. Further analysis indicated that some 8% of the variance in processing dimensions was redundant with 44% of the variance in achievement. Unlike prior findings with mentally retarded children, the present results indicated that simultaneous-successive dimensions accounted for little variance in classroom achievement.

Current practices in evaluating motor behavior of disabled children.

Current practices in evaluating motor behavior were studied in a sample of facilities providing services to children in the United States and Canada. Two hundred and fifty-six supposedly different published and unpublished tests were reported in use by a variety of disciplines. Respondents reported dissatisfaction with many of the tests and also indicated a general pattern of misusing the tests in relation to the disability groups and age ranges for whom the tests were developed. Results are discussed in relation to the need for an interdisciplinary approach to knowledge development and personnel preparation in the area of motor evaluation.

Teaching prereading skills to disabled children.

A Swedish survey suggests that less than 10% of children with Down's syndrome between 7 and 10 years of age are able to read a simple text. Children with Down's syndrome in a programme for early language intervention show clear progress in reading ability. The programme focuses on general language development, auditory and visual perception, and fine-motor ability. Prereading skills are stimulated in a systematic way such as identifying and discriminating sound-patterns at the level of the word, the syllable and the segments, and children are helped to categorize forms, to discriminate and understand pictures, to recognize the direction of reading, and to realize the grapheme-phoneme correspondence.

The development of precursors to literacy in mentally disabled children.

This study aimed to investigate metalinguistic precursors to literacy in mentally handicapped children, with a view to improve literacy training in this population. Language proficiency and environmental literacy factors were explored, and an analysis was made of proficiency in several metalinguistic tasks (i.e., higher level language awareness skills). Six children who are educable mentally retarted, with mental ages between five and seven years (chronological ages between six and sixteen years) were assessed. Results showed that environmental factors of literacy socialisation and print awareness were adequate, with reasonable exposure to literacy artifacts and events. Language abilities were also adequately developed. Isolated metalinguistic skills (e.g., phonemic segmentation) had developed in those children who had received reading instruction, however, most metalinguistic precursors were not adequately developed for their mental ages and were below a five year level.

Sequelae of antireflux surgery in profoundly disabled children.

Between 1976 and 1989 an antireflux operation (193 Nissen; 5 Thal) was performed in 198 children with profound neurological impairment (NI). Etiology of the NI was a syndrome in 24%, congenital in 30%, and acquired in 46%. The most frequent symptoms of gastroesophageal reflux (GER), vomiting and pneumonia, were significantly reduced (P less than .05) after the antireflux operation. Postoperatively, 141 children (71%) developed return of one or more symptoms that had been preoperatively associated with GER, whereas 57 patients (29%) remained asymptomatic. Of the children with symptoms, 86 (61%) underwent diagnostic testing to exclude recurrent GER and 55 (39%) had no diagnostic evaluation. Recurrent GER was documented in 31 patients and a mechanical problem with the fundoplication in 18 children, an operative failure rate of 25%. The symptom-free interval following the antireflux operation averaged 11 months postoperatively; return of symptoms showed no statistical relationship to the etiology of NI, presence of seizures, or degree of muscle tone. The majority of children required multiple outpatient or emergency department visits for evaluation of these symptoms or assessment of gastrostomy tube problems. Survival of all children was 71% at an average postoperative follow-up of 3.5 years.

Teaching developmentally disabled children with chronic illness to swallow prescribed capsules.

Child noncompliance with prescribed medical regimens, including nonacceptance of oral medication, frequently impedes medical treatment and achievement of clinical aims. During this study, we used a single-subject experimental design to evaluate the effectiveness of a capsule-swallowing training curriculum specifically developed to promote acceptance of oral medication by multihandicapped children. Four such children participated, each diagnosed with a chronic pediatric illness requiring daily intake of oral medication. Training consisted of verbal instruction, demonstration, reinforcement for swallowing candies/capsules progressively larger in size, ignoring mild inappropriate behavior, and gradually providing less guidance and structure. In each case, the curriculum produced routine independent swallowing of prescribed capsules/tablets. Follow-up assessments, coupled with parent satisfaction ratings, suggest that skill acquisition was both enduring and clinically significant. This study validates a brief, readily exportable, and effective approach to teaching handicapped children to swallow capsules.

Seroepidemiological study of toxoplasmosis in intellectual disability children in rehabilitation centers of northern Iran.

Serological studies revealed that toxoplasmosis has world wide distribution. Although the infection by Toxoplasma gondii is widely prevalent in humans and animals, the disease is uncommon and most of the acquired infections are asymptomatic. The important aspect of this parasitic infection is the probable danger of congenital transmission and its severe effects on the fetus. There have been many reports about the prevalence of anti-T. gondii antibody among different groups of people in Iran; however the epidemiological data in intellectual disability (ID) persons are rare. This study was performed to evaluate the seroprevalence of toxoplasmosis among the inhabitants of rehabilitation centers of northern Iran. A total of 336 serum samples (161 males, 175 females) were examined for the IgG antibodies by indirect immunofluorescense technique. First of all, 1:50 titer dilution was tested, in the cases of positive result, further dilutions (1:100, 1:200, 1:400, 1:800, 1:1600, and 1:3200) were prepared and the last dilution was recorded. Among 336 sera, 77.4% showed seropositivity by IFAT. The positive rates of males and females were 77.6% (125/161) and 80% (140/175), respectively. However, there were no significant differences between sexes. Comparing the age groups, the highest seropositive rate showed in 19 or higher, and their rates had a tendency to increase with age. Prevalence of the infection in 10 rehabilitation centers was not significant either. Nevertheless, our data (77.4%) in rehabilitation centers in northern Iran suggest that infection is the same as in many other reports in normal population in this area, therefore toxoplasmosis is not a major problem in rehabilitation centers of this geographical area.

The grief-relief process: coping with the life and death of physically and mentally disabled children.

Many parents of children with severe physical and mental deficits appear to be in conflict between two ambivalent emotions, wanting to live with their child and needing to be relieved from their child's constant suffering. This internal struggle may become a life-long "grief-relief process" for the parents that is manageable but unresolved. The emotional conflict may result in a subconscious or conscious death wish for the child. The conflict reaches its peak when etiology, surgery, and prognosis are discussed and when the child dies. It has been noted that with the death of the child there may be a rapid movement from grief to a sense of relief. This has been referred to as the "grief-relief phenomenon." Though relief appears soon, the period of bereavement may be long and painful. Consequently, the importance of long-term follow-up has been emphasized. Practical suggestions have been offered to allied health professionals working with these parents on a daily basis. This article has concerned itself primarily with the emotional adjustment of parents to children with severe deficits. The grief-relief phenomenon may also be applicable in relation to other populations, such as elderly or terminally ill patients who are constantly in pain and suffering.

Chronic sorrow in mothers of chronically ill and disabled children.

A qualitative study is presented following the hybrid model of concept development to examine the emotions present in mothers who care for their chronically ill children at home. In particular the study attempts to examine the presence or nonpresence of chronic sorrow in three mothers through the use of observation and intensive interview techniques and by following the Schatzman and Strauss (1973) method of field research. The population for this study varied in diagnosis, sex, age, prognosis, and family structure. The commonalities included an uncertain future, a significantly changed life-style as a result of the child's illness, and the presence of nursing care in the home. The emotion called chronic sorrow, introduced in 1962 by Olshansky, has had limited exposure in the literature. The concept was originally intended for examinations of parents of severely mentally retarded children. Recently it has been examined in varied populations. Although many different reactions have been presented in the literature regarding the emotions of parents of chronically ill children, chronic sorrow has not been one of them. The examination of this emotion has been disease specific. The presence of this emotion in this population has implications for nurses working in all care settings.

[Long-term results with dental treatment concepts for disabled children].

More than 10 years ago 400 mentally and physically handicapped children aged 3 to 18 years were included in a dental care program to improve their oral health status. Besides dental treatment a comprehensive preventive program (tooth brushing, application of fluorides, dietetic recommendations) was carried out. The results prove a significant caries reduction and an increase in caries free children. A reduction of dental plaque and marginal inflammations were also observed. To prevent the carious destruction of the dentition of the handicapped, these patients should receive regular prevention-oriented dental care from the age of 3 years.

A new method for toilet training developmentally disabled children.

20 profoundly retarded children (4 to 12 yr.) were trained, using a variety of relaxation and tension activities designed to help them differentiate and gain control of the toileting musculature. Operant techniques were used to reinforce appropriate urination. The post-training scores of the experimental and control groups differed significantly for both accidental and appropriate urination.

A rear support walking frame for severely disabled children with cerebral palsy: initial development.

Ambulation for patients with total body involved cerebral palsy poses greater problems than those encountered in providing reciprocal walking for thoracic lesion paraplegic subjects. Experience with a prototype system showed that an orthosis which controls the movement of the lower limbs, in combination with a walking frame giving anterior support, enables such patients to walk. Despite shortcomings which restricted the use of the system to an indoor environment it provided a sound basis on which to examine walking frames to address the problems which had been identified. A review of these devices showed that the most effective means of achieving this aim is the use of a wheeled walking frame which provides vertical support and truncal alignment via a sprung pantograph mounted to the rear of the patient (rear support walking frames). Trials were conducted with two existing rear support walking frames. These indicated their potential for severely disabled patients, but also identified the need for higher stiffness in the structure and more sensitive control of vertical support to be achieved if effective ambulation in a wider range of environments was to be made possible for the target group. Prototypes based on an existing frame, which took account of the specification requirements, were produced for four new total body involved cerebral palsy patients with the same degree of walking dysfunction. Three of the patients were able to walk in a much wider variety of environments than any patient in the original system. A number of other issues related to transfer and steering were identified as requiring further development.

Sensory extinction: a procedure form eliminating self-stimulatory behavior in developmentally disabled children.

This study was designed to investigate the role of sensory reinforcement in the motivation of self-stimulation. If self-stimulatory behavior is maintained by its sensory consequences, such as the proprioceptive, auditory, or visual stimulation it produces, then such behavior should extinguish when those sensory consequences are not permitted. The present study introduces a new procedure, Sensory Extinction, in which certain sensory consequences are masked or removed, to examine whether self-stimulation is operant behavior maintained by sensory reinforcement. The effectiveness of Sensory Extinction was assessed by a reversal design for each of three autistic children, and the results showed the following. First, self-stimulation reliably extinguished when a certain sensory consequence was removed, then increased when that consequence was permitted. This was replicable within and across children. Second, different Sensory Extinction procedures were required for different self-stimulatory behaviors, since the sensory reinforcers supporting them were idiosyncratic across children. Finally, regarding clinical gains, the data suggest that Sensory Extinction may be a relatively convenient and rapid alternative for the treatment of self-stimulation. The present findings extend the efficacy of extinction as a behavior-modification technique to instances in which the reinforcer is purely sensory. The implications of these results for the treatment of other forms of deviant behavior are discussed.

Intelligence as a predictor of nonverbal learning with learning-disabled children.

Although the notion that the WISC-R measures children's learning proficiency is widespread, there are few data to support this hypothesis. The present study concerned the prediction of learning proficiency on the basis of scores on the WISC-R with 60 children referred because of classroom learning difficulties. The single best predictor, WISC-R Coding, accounted for over 50% of the variance in a controlled nonverbal paired associate learning measure. The multiple correlations for the dependent measures of trials to criteria and number of correct responses were in the 90s. In each case, the Coding and Similarities subtests, with Vocabulary in opposition, proved to be the most potent predictors of nonverbal learning.

Sensory process instruction with learning disabled children.

To determine whether the use of a teaching method geared to an individual learner's dominant perceptual modality would increase level of learning and the efficiency with which that level was achieved on a selected learning task 60 children (8 to 12 yr. old) were divided into three groups of 20 each based upon performance on two perceptual screening procedures. In the instructional phase the subject was given information to be mastered under the following three sensory modalities, Auditory-Vocal-Motor, a Visual-Vocal-Motor, and Combination channel. A two-way analysis of variance yielded significant main effects for training in the visual and combined conditions only.

Delivery of wheelchairs to disabled children.

In a follow-up study from a children's wheelchair clinic the delivery times for 120 wheelchairs ordered during 1973--7 were analysed. Delivery delays were considerable: only 22 of the 120 chairs were delivered within one month and 69 within three months, while 21 took over six months to arrive. Factors such as the type of chair ordered, the need for modifications, and the centre handling the transaction did not influence delivery time. Administrative delays may be an important contributory factor.

Development of cooperative and competitive play responses in developmentally disabled children.

A behavior management procedure for training cooperative and competitive social play was investigated. Subjects were 5 EMR children who had marked behavior and communication disorders. Baseline data indicated that the subjects exhibited no competitive responses and low levels of cooperative play. Upon instituting a token-praise-feedback procedure, the experimenters observed increases in cooperative play as well as small increases in competitive play. Reinstating the token-feedback procedure after reversal resulted in high levels of competitive play with no change in cooperative play. Several explanations were offered to account for these results.

Construct validity of the In-Hand Manipulation Test: a discriminant analysis with children without disability and children with spastic diplegia.

OBJECTIVE: This study examined the construct validity of the In-Hand Manipulation Test (IMT) by assessing the test's ability to discriminate between samples of children with and without known fine motor problems. METHOD: The IMT was administered to 55 children without known fine motor problems and 24 children with spastic diplegia who had mild to moderate fine motor problems. Construct validity was estimated by evaluating how accurately the IMT classified the children as having or not having fine motor problems on the basis of total score. RESULTS: A discriminant analysis indicated that IMT total score correctly classified 83.33% of the participants as having or not having fine motor problems. CONCLUSION: The IMT has adequate construct validity to classify the participants of this study and for continued use as a research instrument to assess children's in-hand manipulation skills. Additional validity studies of the IMT are needed with other samples of children before its use for clinical purposes.
