Loss of hand function is a core feature of Rett syndrome. This article describes longitudinal hand function at 3 time points for 72 subjects participating in the Australian Rett Syndrome Database. Approximately 40% of subjects with some grasping…

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,…

Objectives - It has been assumed that the sterotyped hand movements in Rett syndrome are symmetrical, midline and that they prevent purposeful use of the hands. Their relationship with respiration has not been previously explored. Material and…

PURPOSE: Rett syndrome is a severe neurodevelopmental disorder mainly affecting females and usually linked to mutations in the methyl-CpG-binding protein 2 gene, with an estimated prevalence of 1 in 10,000 live female births. Clinical features which…

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…

Previous studies demonstrated the efficacy and safety of prolonged-release melatonin in children and adolescents with neurodevelopmental and behavioral disorders. The long-term effectiveness and safety of prolonged-release melatonin treatment were…

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…

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…

Aim: To quantify, in individuals with Rett syndrome with the capacity to walk, walking-based activity and sedentary time, and to analyse the influences of age, walking ability, scoliosis, and the severity of epilepsy. Method: Sixty-four participants…

Rett syndrome is characterized by loss of motor and social functions, development of stereotypic hand movements, seizures, and breathing disturbances. This study evaluates the presence of overnight respiratory disturbances. Polysomnography in…

Rett syndrome, a progressive neurodegenerative disorder described only in female subjects, is manifested by a wide spectrum of behavioral and motor abnormalities. We studied 32 patients with this disorder, ages 30 months to 28 years old, and…

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…

Background: Rett syndrome is a pervasive neurological disorder with impaired gait as one criterion. This study investigated the capacity of three accelerometer-type devices to measure walking activity in Rett syndrome. Methods: Twenty-six…

Rett's syndrome is a progressive disorder that occurs in females and is characterized by autistic behavior, dementia, ataxia, loss of purposeful use of the hands, and seizures. Patients with Rett's syndrome have been observed to have stereotyped hand…

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…

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…

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,…

Rett syndrome (RTT), a rare but severe neurological disorder is associated with a mutation in the methyl CpG binding protein 2 (MECP2) gene on the X chromosome occurring in 1:9000 live female births. Apparently normal development is followed by a…

Stereotypic hand movements are a feature of Rett Syndrome but few studies have observed their nature systematically. Video data in familiar settings were obtained on subjects (n = 144) identified from an Australian population-based database. I-land…

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…

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…

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…

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…

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:…

The purpose of this study was to examine the effect of hand splints and one elbow restraint on persistent stereotypic hand movements of four girls with Rett's syndrome. Among the most characteristic features of Rett's syndrome are stereotypic hand…

Rett Syndrome (RS) is a neuro-developmental disorder, predominantly affecting females, resulting in severe mental retardation and neuro-behavioral disability. Some RS theoreticians hypothesize that behaviors that are neurologically driven are not…

Incessant hand to mouth movements are often noted as part of the movement disorder of the hands in the Rett syndrome (RS). Elbow splints were designed to inhibit this behavior and prevent further injury to the hands. A study of eight RS patients was…

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…

© 2016 Downs et al. Rett syndrome is a pervasive neurodevelopmental disorder associated with a pathogenic mutation on the MECP2 gene. Impaired movement is a fundamental component and the Rett Syndrome Gross Motor Scale was developed to measure gross…

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…
