Article Synopsis
- * Nine stroke patients participated by performing ankle and knee movements, with an algorithm determining the level of assistance needed for each repetition.
- * Results showed that patients needed support for a significant percentage of ankle movements (44%) but much less for knee movements (5%), and the fatigue experienced was mild to moderate. The study suggests this method is feasible and encourages future clinical application research.
Increasing the independence of individuals with tetraplegia is a challenging task. One potential solution is to allow for use of an assistive robotic manipulator (ARM), when solving tasks in personal and remote space. There is a lack in available control interfaces that are suitable for severely disabled individuals.

To create a system for early rehabilitation of lower extremities in these patients, we combined the robotic manipulator ROBERT® with electromyography (EMG)-triggered functional electrical stimulation (FES) and developed a novel user-driven Assist-As-Needed (AAN) control. The method is based on a state machine able to detect user movement capability, assessed by the presence of an EMG-trigger and the movement velocity, and provide different levels of assistance as required by the patient (no support, FES only, and simultaneous FES and mechanical assistance).

Cancer Epidemiol Biomarkers Prev

Background: Effective screening for oropharyngeal cancer is lacking. Four oncogenic HPV clearance definitions were explored to understand long-term natural history for persistent oncogenic oral HPV (oncHPV), the precursor of oropharyngeal cancer.
Methods: Prospective multicenter cohort of participants living with/at-risk for HIV, with oral rinse and gargle samples collected every 6 to 12 months for up to 10 years and tested for oncHPV.
Background: Human papillomavirus (HPV)-related oropharyngeal cancer screening is being explored in research studies, but strategies to identify an appropriate population are not established. The authors evaluated whether a screening population could be enriched for participants with oncogenic HPV biomarkers using risk factors for oral HPV.
Methods: Participants were enrolled at Johns Hopkins Hospitals and Mount Sinai Icahn School of Medicine.
