Knee Joint01:23

Knee Joint

3.2K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Control System Problem01:21

Control System Problem

434
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Combinatorial Gene Control02:33

Combinatorial Gene Control

9.7K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

471
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Control Systems01:10

Control Systems

1.9K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.
At the heart...

Controller Configurations01:22

Controller Configurations

380
Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation.
Control-system compensation involves various configurations, most commonly series or cascade compensation, in which the controller...

    Area of Science:

    • Rehabilitation Engineering
    • Biomedical Devices
    • Assistive Technology

    Background:

    • Knee rehabilitation often requires intensive supervision, increasing costs and limiting accessibility.
    • Existing exoskeleton devices may lack adaptive support and patient progress monitoring.
    • The need for autonomous and cost-effective rehabilitation solutions is growing, especially for home-based settings.

    Purpose of the Study:

    • To design and implement an assist-as-needed controller for a knee rehabilitation exoskeleton.
    • To integrate a patient recovery tracking system into the exoskeleton.
    • To enhance user autonomy and reduce the need for constant supervision during rehabilitation.

    Main Methods:

    • Utilized force sensing resistors (FSR) to measure exoskeleton support levels and control actuator torque.
    • Employed surface electromyography (sEMG) signals from upper leg muscles to detect user intent (start, stop, directional movement).
    • Developed a visual display for real-time recovery status and historical data tracking.

    Main Results:

    • The system successfully provided users with visual feedback on recovery progress and history.
    • Users maintained full autonomy in controlling the exoskeleton device.
    • Preliminary results indicate the potential for reduced supervision, time, and cost in rehabilitation.

    Conclusions:

    • The developed assist-as-needed controller and recovery tracking system enhance exoskeleton-based knee rehabilitation.
    • The system promotes user autonomy and offers a viable solution for home-based or telerehabilitation.
    • Implementation can lead to significant cost and time savings in the rehabilitation process.
