- ObjectivesWe developed clinical guidelines for the management of bone health in Rett syndrome through evidence review and the consensus of an expert panel of clinicians.MethodsAn initial guidelines draft was created which included statements based upon literature review and 11 open-ended questions where literature was lacking. The international expert panel reviewed the draft online using a 2-stage Delphi process to reach consensus agreement. Items describe the clinical assessment of bone health, bone mineral density assessment and technique, and pharmacological and non-pharmacological interventions.ResultsAgreement was reached on 39 statements which were formulated from 41 statements and 11 questions. When assessing bone health in Rett syndrome a comprehensive assessment of fracture history, mutation type, prescribed medication, pubertal development, mobility level, dietary intake and biochemical bone markers is recommended. A baseline densitometry assessment should be performed with accommodations made for size, with the frequency of surveillance determined according to individual risk. Lateral spine x-rays are also suggested. Increasing physical activity and initiating calcium and vitamin D supplementation when low are the first approaches to optimizing bone health in Rett syndrome. If individuals with Rett syndrome meet the ISCD criterion for osteoporosis in children, the use of bisphosphonates is recommended.ConclusionA clinically significant history of fracture in combination with low bone densitometry findings is necessary for a diagnosis of osteoporosis. These evidence and consensus-based guidelines have the potential to improve bone health in those with Rett syndrome, reduce the frequency of fractures, and stimulate further research that aims to ameliorate the impacts of this serious comorbidity.

- 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 Rett syndrome. Methods: Forty-two girls and women with Rett syndrome (median 18.4 years, range 2.4–60.9 years) were assessed for clinical severity, gross motor skills, and mobility. To measure walking capacity, 27 of this group completed a 2MWT twice on two different assessment days. To assess walking performance, the FMS-RS was administered to the total sample of parents (n = 42) on two occasions approximately one week apart. Results: There were negative correlations between clinical severity and 2MWT (r = −0.48) and FMS-RS (r = −0.60–0.66). There were positive correlations between gross motor skills and mobility and 2MWT (r = 0.51, 0.43) and FMS-RS (r = 0.71–0.93, 0.74–0.94), respectively. Test–retest reliability for the 2MWT was good with high intraday and interday correlations (ICC = 0.86–0.98). For the 2MWT, the standard error of measurement was 13.8 m and we would be 95% confident that changes greater than 38 m would be greater than within subject error. There was good test–retest reliability for all three distances on the FMS-RS (ICC = 0.94–0.99). Conclusions: Walking capacity as measured by the 2MWT showed expected but limited relationships with measures of different constructs, providing some support for concurrent validity. Walking performance as measured with the FMS-RS was more strongly consistent with other clinical measures supporting its concurrent validity. Test–retest reliability was good for both the FMS-RS and the 2MWT. Therefore, these measures have the potential to be used in clinical practice and research. Implications for RehabilitationWalking is one of the commonest daily physical activities in ambulant girls and women with RTT. Comprehensive knowledge about the walking abilities in this population is limited.Evidence of validity and test–retest reliability have been demonstrated for the modified two-minute walk test (2MWT) and the Rett syndrome-specific functional mobility scale (FMS-RS).The 2MWT and FMS-RS offer detailed information of the capacity and performance of walking, respectively, in girls and women with RTT

- Rett syndrome (RTT) is a rare neurodevelopmental disorder usually affecting females. It is associated with intellectual and multiple disabilities leading to a high level of dependency in all aspects of daily living including participation in physical activities. This study explored facilitators and barriers to “uptime” (non-sedentary) activities in Danish girls and women with RTT as perceived by parents and professionals using focus groups. Through thematic analysis, one central theme emerged: a constant balance to do the best thing for the girl or woman. Within the central theme, five subthemes of facilitators and barriers were identified relating to the individual and the physical, organizational, social, and attitudinal environments. Environmental barriers can be reduced through policy and management-level changes in health promotion and strong advocacy of physical activity by health professionals. Targeting both facilitators and barriers of “uptime” activities enables the planning and implementing of health-promoting interventions in individuals with RTT.

- Background: Rett syndrome (RTT) is a rare neurodevelopmental disorder leading to multiple disabilities and high dependency on caregivers. This study aimed to: (1) describe the patterns of sedentary time and daily steps and (2) identify the association of individual and environmental characteristics with sedentary time. Methods: All Danish females with RTT older than 5 years of age and with a MECP2 mutation were invited to participate. The activPAL and StepWatch Activity Monitor (SAM) were worn by participants for at least four days. Sedentary time and step counts were plotted by time to examine daily activity patterns. Associations between sedentary time and individual and environmental covariates were assessed with linear regression models. Results: The median (interquartile range) age of participants was 22.0 (14.3–36.5) years. On average 83.3% (standard deviation 13.9%) of waking hours were spent in sedentary behaviours (n = 48) and the median (interquartile range) daily step count was 5128 (2829–7704) (n = 28). Females older than 33.5 years, and those unable to walk independently were more sedentary. Conclusions: This study demonstrated high levels of sedentary time and low daily step counts in a Danish population of females with RTT. Advancing age and lower walking skills were associated with higher levels of sedentary time.Implications for RehabilitationSedentary lifestyles in individuals with disabilities have a negative impact on health and quality of life.High levels of sedentary time and low daily step counts were demonstrated in a Danish population of females with Rett syndrome.Advancing age and inability to walk independently were strongly associated with higher levels of sedentary time in females with Rett syndrome.Understanding patterns of sedentary behaviour and physical activity can aid health care professionals in developing health-promoting physical activity interventions.
