Individuals with Rett syndrome (RTT) can have variable manifestations of stereotypies. In this nation-wide cross-sectional study, we recruited all individuals with RTT in Taiwan diagnosed as RTT by neurologists based on genetic findings and…

This study characterizes cardiorespiratory dysregulation in young girls with MECP2 mutation-confirmed Rett syndrome (RS). Respiratory inductance plethysmography of chest/abdomen and ECG was obtained during daytime wakefulness in 47 girls with MECP2…

This study was designed to specifically characterize the autonomic phenotype of cardiorespiratory dysregulation during the nighttime in young girls with MECP2 mutation-confirmed Rett Syndrome (RS), studied in their home environment. Computerized…

BACKGROUND: Rett syndrome is a neurodevelopmental disorder that almost exclusively affects females. In addition to neurodevelopmental regression and loss of hand skills, apraxia, deceleration of head growth, and increasing spasticity and scoliosis, a…

Stereotypies in Rett syndrome (RTT) are a diagnostic hallmark present in all stages of the disease, but descriptions of movement disorders in adults are very scant. Among 30 patients with RTT followed-up at San Paolo Hospital in Milan, we selected…

The purposes of this study were to replicate a recent report of the positive effects of hand splinting on the stereotypic hand movement of children with Rett syndrome and to evaluate the generality of these results to a different setting. Two…

Rett syndrome (RS) is one of the best human models to study movement disorders. Patients evolve from a hyperkinetic to a hypokinetic state, and a large series of abnormal movements may be observed along their lives Such as stereotypies, tremor,…

Background: Hand stereotypies are considered a hallmark of Rett syndrome (RTT) and are usually described as symmetric movements at the midline. However, related pathologies may show the same type of involuntary movement. Furthermore, patients with…

This study was aimed at extending the use of assistive technology (i.e., photocells, interface and personal computer) to support choice strategies by three girls with Rett syndrome and severe to profound developmental disabilities. A second purpose…

We assessed a microswitch-based program to improve self-determination to access to preferred stimuli and to foster locomotor behavior by two girls with Rett syndrome and multiple disabilities. To enhance the first behavior (access to preferred…

Background: The repertoire of measures of walking in Rett syndrome is limited. This study aimed to determine measurement properties of a modified two-minute walk test (2MWT) and a modified Rett syndrome-specific functional mobility scale (FMS-RS) in…

A single-subject rapidly alternating treatment design was used to compare the effectiveness of bilateral band splints and an elbow orthosis in decreasing stereotypic band behaviors and increasing toy play in 2 children with Rett syndrome. The…

Polygraphic recordings in the awake state and during sleep were performed in two girls with Rett syndrome, aged 9 y and 17 y, in order to characterize the clinically manifest breathing disorder of these patients. Primary hyperventilation was…

Rett syndrome causes severe autonomic dysregulation, probably due to brainstem dysfunction. Because the brainstem plays a decisive role in cardiorespiratory regulation during sleep, we investigated cardiorespiratory function in 12 girls with Rett…

Rett syndrome (RTT) considerably limits participation in daily activities but food and mealtimes are most often motivating activities for persons with RTT. The aim of this study was to investigate whether there is a difference in participation during…

Rett syndrome (RTT) is a neurodevelopmental disorder primarily affecting females. It is characterized by apparently normative development of motor and communicative abilities followed by deterioration in these domains. Stereotypic hand movements are…

Aberrant sleep patterns are commonly experienced by girls with the Rett syndrome. In this investigation, the problematic sleep of three girls with the Rett syndrome was regulated using a bedtime fading procedure with response cost. The treatment…

Previous studies on the characteristics of disturbed sleep/wake patterns in children with the Rett syndrome have yielded inconsistent findings. In the current study, momentary time sampling procedures were used to measure the sleep/wake patterns of…

Few studies have examined the extent to which functional hand-use may be taught to girls with Rett syndrome after those skills have been lost. In this investigation, five females with classic Rett syndrome taught to feed themselves using a method of…

Sleep disturbances in children with neurodevelopmental disabilities are common and frequently difficult to treat with conventional pharmacological and behavioural methods. Melatonin is a pineal hormone known to be important in the regulation of the…

The sleep patterns of a cohort of 83 Rett syndrome females were characterized using a sleep diary for 7 consecutive days and nights and compared with normative sleep data. The mean total sleep time of the cohort was 10.75 h, daytime sleep 0.77 h,…

The purpose of this multiple baseline study was to examine the effect of bilateral hand splints on the persistent stereotypic hand movements of three adolescent girls with Rett syndrome. Among the most characteristic features of Rett syndrome are…

BACKGROUND: Oropharyngeal dysphagia encompasses problems with the oral preparatory phase of swallowing (chewing and preparing the food), oral phase (moving the food or fluid posteriorly through the oral cavity with the tongue into the back of the…

Purpose: Early screening and intervention for dysphagia is crucial to offset potential outcomes such as compromised nutrition or reduced respiratory function. Current paediatric dysphagia screening tests are subjective with poor sensitivity and…

We studied the circadian rhythm of serum melatonin levels in two patients with classical Rett syndrome having severe sleep disorders; serum melatonin levels were measured before and during melatonin treatment using radioimmunoassay. Patient 1 had a…

Objectives: Rett syndrome (RS) is a neurodevelopmental disorder and the second major cause of mental retardation in females. The aim of this study was to evaluate swallowing problems of RS patients by endoscopic assessment and compile a list of…

Nine girls with Rett syndrome (mean age, 10.1 years) were monitored 24 hours a day over a period of 10 weeks using wrist actigraphy. Baseline sleep-wake patterns were assessed for 1 week. Subsequently, patients underwent a 4-week melatonin treatment…

We examined the psychometric properties of one part of the Sleep Questionnaire developed by Simonds and Parraga (SQ-SP; 1982), a questionnaire that is frequently used to explore sleep problems and behaviors related to sleep in individuals with…

INTRODUCTION: Rett syndrome (RTT) is a neurological disorder usually associated with a mutation in the MECP2 gene. Conductive Education (CE) is an educational approach that has not yet been explored with regard to children with RTT. OBJECTIVE:…

BACKGROUND: To investigate the feasibility of a physical exercise programme with treadmill for persons with Rett syndrome (RS) in order to promote fitness and health. METHODS: A daily training programme on a treadmill was designed for four females…

Aim-To investigate breathing rhythm and brain stem autonomic control in patients with Rett disorder. Setting-Two university teaching hospitals in the United Kingdom and the Rett Centre, Sweden. Patients-56 female patients with Rett disorder, aged…

Rett syndrome arises from a mutation on the X chromosome and occurs with prevalence in the general population in 1:10,000 women. Its major nutritional consequences require that health providers recognize early signs of eating difficulties and slowing…
