Feedback Inhibition00:46

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Tactile and Chemical Senses

727
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Effects of feedback01:24

Effects of feedback

1.0K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Feedback control systems

691
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Area of Science:

  • Biomedical Engineering
  • Neurorehabilitation
  • Human-Computer Interaction

Background:

  • Post-stroke functional recovery necessitates effective rehabilitation and mobility training.
  • Traditional methods may not always be cost-effective or efficient for optimal patient outcomes.
  • Novel approaches are needed to enhance motor recovery and accessibility in stroke rehabilitation.

Purpose of the Study:

  • To design and develop an efficient rehabilitation training system for post-stroke users.
  • To investigate the efficacy of a bilateral training method with tactile feedback for motor recovery.
  • To assess the feasibility of a low-cost system for home-based stroke rehabilitation.

Main Methods:

  • A bilateral training system was developed using a low-cost Kinect sensor for motion tracking.
  • Tactile feedback (vibration) was implemented to guide and reinforce movements.
  • Training protocols included "contralateral arm matching" and "both arms moving together" for shoulder and elbow movements at specific angles.
  • Clinical assessments (Fugl-Meyer Assessment, Wolf Motor Function Test) and goniometer measurements were used to evaluate progress.

Main Results:

  • A single participant with hemiparesis showed improvements in several assessed tasks after six weeks of training.
  • The system successfully extracted body joint position data using the Kinect sensor.
  • Clinical assessments indicated positive effects of the training system on motor function and proprioception.

Conclusions:

  • The developed rehabilitation system is feasible for training post-stroke users.
  • The bilateral training method with tactile feedback shows promise for enhancing motor recovery.
  • The system's low cost and potential for self-training offer a valuable tool for stroke survivors' rehabilitation.
