PURPOSE: This pilot study assesses the feasibility of using PedBotHome to promote adherenceto a home exercise program, the ability of the device to withstand frequent use, and changes in participant ankle mobility. PedBotHome is a robotic ankle device with integrated video game software designed to improve ankle mobility in children with cerebral palsy. METHODS: 8 participants enrolled in a 28-day trial of PedBotHome. Ankle strength, range of motion, and plantarflexor spasticity were measured pre- and post-trial. Performance was monitored remotely, and game settings were modified weekly by physical therapists. RESULTS: Four participants met the study goal of 20 days of use. There were statistically significant improvements in ankle strength, spasticity, and range of motion. CONCLUSIONS: PedBotHome is a feasible device to engage children with static neurological injuries in ankle home exercise. This pilot study expands the paradigm for future innovative home-based robotic rehabilitation.

We apply the event-chain Monte Carlo algorithm to classical continuum spin models on a lattice and clarify the condition for its validity. In the two-dimensional XY model, it outperforms the local Monte Carlo algorithm by two orders of magnitude, although it remains slower than the Wolff cluster algorithm. In the three-dimensional XY spin glass at low temperature, the event-chain algorithm is far superior to the other algorithms., Comment: 6 pages, 7 figures

Chronic conditions carry with them strong emotions and often lead to charged relationships between patients and their health providers and, by extension, patients and health researchers. Persons are both autonomous and relational and a purely cognitive model of autonomy neglects the social and relational basis of chronic illness. Ensuring genuine informed consent in research requires a thorough understanding of how participants perceive a study and their reasons for participation. Surveys may not capture the complexities of reasoning that underlies study participation. Contradictory reasons for participation, for instance an initial claim of altruism as rationale and a subsequent claim of personal benefit (therapeutic misconception), affect the quality of informed consent. Individuals apply principles through the filter of personal values and lived experience. Authentic autonomy, and hence authentic consent to research, occurs within the context of patients- unique life narratives and illness experiences.
