Design and Real-World Evaluation of Eyes-Free Yoga: An Exergame for Blind and Low-Vision Exercise.

People who are blind or low vision may have a harder time participating in exercise due to inaccessibility or lack of encouragement. To address this, we developed Eyes-Free Yoga using the Microsoft Kinect that acts as a yoga instructor and has personalized auditory feedback based on skeletal tracking. We conducted two different studies on two different versions of Eyes-Free Yoga: (1) a controlled study with 16 people who are blind or low vision to evaluate the feasibility of a proof-of-concept and (2) an 8-week in-home deployment study with 4 people who are blind or low vision, with a fully functioning exergame containing four full workouts and motivational techniques.

Fluctuations in body satisfaction across situations.

Although the variable nature of body image was underscored by Schilder (The image and appearance of the human body. New York: International Universities Press, 1950), few investigators have addressed the stability of body image or its sensitivity to variation in environmental or situational conditions. Most researchers have assumed that body image is a stable characteristic.

The Lennox-Gastaut syndrome: electroencephalographic characteristics, clinical correlates, and follow-up studies.

Electroencephalographic and clinical findings are reported for 100 patients with the Lennox-Gastaut (LGS) triad of slow bilateral spike and wave (BSW), retardation and multiple seizures. Neurological and mental deficits were frequently observed, especially in patients who developed seizures before age 1 yr. More than half of the patients had focal epileptiform discharges that peaked in occurrence at age 4-6 yrs.

Acute hypertensive encephalopathy in minimal change nephrotic syndrome.

A 3-year-old child with minimal change nephrotic syndrome (MCNS) developed an acute hypertensive encephalopathy characterized by coma, focal seizures, right hemiparesis, global aphasia and cortical blindness. Episodic hypertension and seizures persisted for 24 h despite intervention with antihypertensive and anticonvulsant therapy. Clinical suspicion of cortical blindness was confirmed by visual-evoked potential studies.

Demography of handedness in two samples of randomly selected adults (N = 2083).

Handedness was examined in relation to sex, race, age, education, occupation, marital status, and religious preferences for two random samples of adults drawn from an urban population. There were statistically significant differences on each variable for the total of 2083 respondents as well as for many subgroups based on combinations of sex, race, and age. The results are compared to previous findings.

The measurement of performance in childhood cancer patients.

The performance status of the child with cancer is an important outcome consideration in pediatric oncology research and practice. However, no single measure for children has been available. This is a report of the development and standardization of such a scale.

Pitfalls in diagnosing brain death in infancy.

A 3-year-old child with phenotypic trisomy 18 syndrome survived 26 days after a cardiopulmonary arrest, secondary to an acute viral illness. The child was deeply comatose. No barbiturates, other sedatives, or aminoglycoside antibiotics had been recently administered.

Normal cerebral radionuclide angiogram in a child with electrocerebral silence.

Pediatric neurologists agree that the determination of brain death in children, and especially retarded children, is difficult and that the criteria used in adult brain death may not be sufficient in pediatric cases. An unusual case of sustained electrocerebral silence on electroencephalogram (EEG) in a three-year-old retarded comatosed child with preserved intracerebral perfusion documented by a series of cerebral radionuclide angiograms (CRAG) is presented. The EEG showing electrocerebral silence represents loss of cerebrum (cortex) function (Barlow 1976).

Toward the development of a play performance scale for children (PPSC).

Performance scales (i.e., Karnofsky), as they measure quality of life, have been used effectively as an integral part of repeated assessment of adult cancer patients for the last several years.

Some comments on Shettel-Neuber and O'Reilly's "handedness and career choice: another look at supposed left/right differences" (1983).

A property of attitudes, namely, the fact that attitudes select facts, is used to comment upon a paper on handedness and career choice.

Central nervous system prophylaxis. Studies showing impairment in verbal skills and academic achievement.

School attendance and school achievement were the parameters studied to assess the pediatric cancer patient's ability to learn and keep pace with their peers. Effects of CNS prophylaxis, as either intrathecal methotrexate (IT) alone or intrathecal methotrexate given in addition to cranial radiation (CRT), were studied in two groups. A third group of cancer patients who received no CNS prophylaxis, and two comparison groups, siblings and a matched sample of children, also participated in the study.

Figure reversals and creativity: a research note.

In a series of studies, Bergum and Bergum (1979a, 1979b) noted a positive relationship between college students' self-perceptions of creativity and their passive rates of ambiguous figure reversal. While these authors suggest that a relationship may also exist between figure-reversal rate and creativity, as assessed by external measures, their research does not support this claim. Indeed, other research has not substantiated a relationship between rate of figure reversal and objective tests of creativity (Bloomberg, 1971; Bergum & Flamm, 1975).

Application of three-dimensional computer reconstruction from computerized tomography to intracranial tumors in children.

A three-dimensional surface reconstruction algorithm was devised from contour information based upon anatomic structures identified by computed tomographic (CT) scanning. The triangular 'tiling' method from which the algorithm was derived accurately reconstructs the surfaces between contours of both supra- and infra-tentorial anatomic sites. Volume and surface area of the lateral ventricles and tumor site were calculated from the surface reconstruction algorithm in four children with intracranial mass lesions.

Hemiplegic migraine in childhood: diagnostic and therapeutic aspects.

Focal neurologic deficits, particularly hemiplegia, are occasionally observed in the pediatric migrainous population during the headache attack and are often mistaken for other neurologic or neurosurgical conditions. Clues to the correct diagnosis, illustrated by three patients in this report are: (1) rapid spontaneous recovery from the acute neurologic deficit, (2) striking electroencephalographic abnormalities, frequently consisting of focal slow waves during the acute stage, with rapid resolution, (3) significant past history of recurrent episodes, and (4) positive family history of migraine. Review of previously reported cases indicates that cerebral arteriography in the acute stage should be avoided if the clinical syndrome is typical.

Craniopharyngioma simulating bilateral internal ophthalmoplegia.

A 15-year-old girl had rapid onset of an apparent bilateral internal ophthalmoplegia. Subsequent evaluation revealed a large craniopharyngioma. It is uncommon for a mass to cause such eye findings and unique for a craniopharyngioma to manifest in this fashion.

Facial nerve schwannoma in a 16-year-old girl.

A 16-year-old girl with unilateral facial nerve schwannoma in the cerebellopontine angle is presented in this report. The characteristic computerized tomography (CT) findings described in schwannomas and the patient's clinical findings established the preoperative diagnosis of a rare but benign tumor in the pediatric age group. The value of early diagnosis of potentially resectable benign tumors is emphasized.

Left-handedness among architects: partial replication and some new data.

As predicted, over a 6-yr. period, more left-handed proportionately than right-handed architecture students successfully completed their 6-yr. program.

Kinetics of primidone metabolism and excretion in children.

The metabolism and excretion of orally administered primidone was studied in 12 children, aged 7 to 14 yr during long-term dosing. Plasma concentrations of primidone (Pr) peaked at 4 to 6 hr and declined exponentially from 6 to 24 hr, with half-life (t1/2) values ranging from 4.5 to 11 hr.

Hypothermic total body washout and intracranial pressure monitoring in Stage IV Reye syndrome.

The number of children in this report treated with either TBW or exchange transfusions is small. Case mortality rates among children with Reye syndrome in Stage IV coma tends to be exceedingly high, varying from 50 to 100%. Intracranial pressure monitoring with the subarachnoid screw may have been an additional factor in increasing our survival data in three patients in the TBW group, since it provided continuous monitoring of ICP and allowed judicious administration of mannitol intravenously.
