Source: Yetsa Tuakli-Wosornu1,2, Jaideep Talwalkar1; 1Yale School of Medicine, 2University of Pittsburgh In the United States, 25% of the general population suffers from one or another type of disability. Ambulatory disabilities, or mobility impairments, represent the most common subcategory, comprising 14% of the country's populace. Different mobility-assistive devices, ranging from canes to scooters, enable increased independence and improved quality of life for those suffering from mobility...

2023
Source: Yetsa Tuakli-Wosornu1,2, Jaideep Talwalkar1; 1Yale School of Medicine, 2University of Pittsburgh In addition to the regular checks of a physical exam, examinations for patients who use wheelchairs should be adapted to address their specific needs. This ensures that the patient's mobility, injury risk, and quality of life are not threatened by extended periods of sitting, potentially without proper weight shifts. Such examination needs healthcare providers that understand these...

Studying the Permeation of FITC and FITC-Ferritin through an In Vitro Blood-Brain Barrier Model
0 Views •
2025
This video demonstrates a method to study permeation through an in vitro blood-brain barrier (BBB) model using astrocytes and endothelial cells on a membrane insert, with free FITC and FITC-loaded ferritin. FITC-ferritin bound to receptors on endothelial cells and crossed the membrane barrier to the lower chamber while free FITC showed restricted permeation and remained in the upper chamber.

2016
A method to establish an in vitro model of blood-brain barrier based on a co-culture of rat brain microvascular endothelial cells and astrocytes is described and validated. This system proved to be a valid tool to study the effect of nanoformulation on the trans-barrier permeation of fluorescent molecules.
FAQs
Measurements translate the person’s body proportions into wheelchair settings. Hip width informs seating space, seat depth relates to body length, and lower-leg length guides the relationship between the seat and footrests. Matching these dimensions helps the user maintain a suitable position while supporting functional mobility and daily activities.
Pelvic and trunk alignment provide a foundation for evaluating support and stability. Clinicians observe whether the individual remains aligned in the chair and whether the configuration supports controlled posture during use. This matters because positioning is assessed together with propulsion, functional reach, and safety rather than as an isolated seating measurement.
Pressure distribution helps indicate whether the seating setup supports comfort and protects vulnerable areas during use. Clinicians consider these findings when assessing cushions and other seating components, alongside posture and stability. Appropriate adjustments may help reduce the risk of pain or skin injury while preserving the person’s ability to use the chair effectively.
A clinician begins by measuring relevant body dimensions, including hip width, seat depth, and lower-leg length. The person then uses the wheelchair while the clinician assesses posture, pelvic and trunk alignment, pressure distribution, stability, propulsion, and functional reach. Findings guide adjustments to supports and configuration, followed by observation of their effect.
The evaluation can guide changes to the seat, back support, cushion, footrests, and armrests. Each component is considered in relation to body dimensions, alignment, pressure distribution, and daily function. Adjusting these elements as a coordinated configuration can improve comfort, positioning, safety, and the person’s ability to move or reach from the chair.
Clinicians use this assessment when selecting or adjusting a wheelchair for a person’s mobility needs and daily activities. It is relevant in rehabilitation and assistive technology practice because the findings connect physical measurements with real use, including propulsion, stability, reach, and comfort. The process can also address changing physical needs over time.
Results show how the wheelchair configuration affects practical performance, including propulsion, functional reach, stability, and positioning. Clinicians can use that information to select targeted adjustments rather than relying only on measurements. A better-matched setup may support safer, more comfortable mobility and help accommodate changes in the individual’s physical needs.
